Secant pile wall is a type of retaining wall which is constructed adjacent to each other. Secant pile wall consists of closely spaced bored cast-in-place piles. This piling works like close interlocking piles. A secant pile wall is created by constructing intersecting reinforced concrete piles. This can be constructed by drilling into the ground through soft ground and rock when there is an increase in groundwater level, a secant pile wall can be used as a dewatering system even before construction work begins on the site.
Secant pile walls are formed by constructing intersecting reinforced concrete piles. Secant pile walls are reinforced with either steel rebar or with steel beams and are constructed by drilling under mud. Primary secant piles are installed first with secondary reinforced secant piles constructed in between primary piles once the latter gains sufficient strength. Pile overlap is typically in the order of 3 inches (8 cm). In a tangent pile wall, there is no pile overlap as the piles are constructed flush with each other.
A secant pile wall consists of overlapping (secant) piles to form structural or cutoff walls and achieve the required water tightness. The design can incorporate steel bars or beams for reinforcement and anchors can provide additional lateral support, if needed.
Secant pile walls are created by drilling or augering a series of overlapping concrete piles reinforced with steel beams or rebar to form a wall. After the initial piles are installed and gain sufficient strength, the secondary piles are installed in between the initial piles to create a continuous and impervious wall.
A Secant Piled Wall is a retaining wall constructed for ground retention prior to excavation. The wall is formed by constructing alternating primary (female) and secondary (male) piles where the secondary piles are partially cut into either side of the primary piles in order to form a continuous impervious structure.
The overlapping concrete piles that form a secant pile wall create a water-resistant barrier which can eliminate issues of scouring caused by tides, wave action, and weather. Secant pile walls can function as temporary or permanent retaining walls and may even be designed to support vertical loads.
Secant pile walls are constructed by drilling holes into the ground and driving steel or concrete “secant” piles into the earth. These secants are then connected to form a wall. In comparison to monolithic walls, secant pile walls are typically less expensive and more flexible in terms of design. They do not require a base layer or a cap layer, which can save money on labor and materials.
Secant pile walls are commonly used for retaining walls, but they can also be used to create underground foundations or as a backfill around existing structures. Secants can be installed close together (two feet apart) or further apart (four feet). The spacing depends on how much weight is expected to be placed on each secant as well as what kind of soil conditions exist where they are being installed.
The most common type of secant pile wall is constructed using threaded rods that connect multiple segments together at each connection point (known as “threaded rod connections”). This allows for easy installation and replacement if necessary, which makes this type of wall ideal for applications that may require frequent maintenance over time (such as retaining walls).
The secant pile wall is a reinforced concrete wall that is used in construction to support the ground. It consists of a single row of vertical reinforcing bars, which are connected to the ground by steel rods driven into the soil. Secant pile walls are commonly used to support the ground in areas where there is the excessive water pressure and soil erosion. They may also be used for retaining structures such as dams and retaining walls.
A secant pile wall consists of a single row of vertical reinforcing bars, which are connected to the ground by steel rods driven into the soil. The reinforcement bars are placed at an angle, known as the “slope,” which varies from 0° to 90°. The slope determines how much stress will be put on each bar in order to hold up against lateral forces such as wind or water pressure. If there were no sloping reinforcement bars, there would be no lateral support provided by them; therefore they would not be able to withstand any pressure put on them by outside forces such as wind or water flow within a dam structure.
What is Secant Pile Wall
Secant pile wall is a type of retaining wall which is constructed adjacent to each other. This retaining wall consists of closely spaced bored cast-in-place piles. This piling works like close interlocking piles. The end of each pile gets fixed with the adjacent pile and forms an interlocked structure, thereby providing stability to the entire structure.

What is Secant Pile Wall used for?
Secant pile walls are used for many purposes. They can be used as a dewatering system, foundation wall, and retaining wall. They can also be used to support structures like buildings or bridges.
Enable and support excavations
Support wing walls
Water cut off for drainage channels
The advantages of using secant pile walls include:
- It is less expensive than other methods of retaining soil or rock (such as earth dams).
- It has fewer environmental impacts than other methods of retaining soil or rock (such as earth dams).
Reasons for using Secant Pile Wall
Secant pile walls are used in several ways and can be easily erected. They are ideal for retaining structures and dewatering systems, as well as dams and retaining structures in mines or tunnels.

Secant pile walls are used for retaining soil or rock. The wall is made from reinforced concrete, which can be waterproofed to eliminate seepage through it.
Secant pile walls are typically constructed using the ‘staggered’ arrangement of the piles, so that they do not intersect with each other at any point, providing greater rigidity and strength to the structure.

A secant pile wall is created by constructing intersecting reinforced concrete piles. The piles are drilled into the ground at an angle, and they meet in the middle to form a solid wall. This type of construction is ideal for retaining walls and foundations, especially when you have a large area to cover or uneven ground.
Secant pile walls are constructed by drilling into the ground through soft ground and rock. This is done to create a secant pile wall.

The secant pile wall is a retaining wall that is used to retain soil or rock. They can be constructed adjacent to each other to form a continuous barrier against landslides, unstable slopes, and erosion.
When there is an increase in groundwater level, a secant pile wall can be used as a dewatering system even before construction work begins on the site. The piles are usually made of steel pipe or wood. They are driven into the ground with specialized equipment until they reach their full depth and length so they can support the weight of whatever material you need to hold back from covering your house or property.
The secant pile retains soil or rock, which extends from the bottom of the excavation to the surface of the ground or foundation level.
It is used to support the ground and foundation at the top of an excavation, usually during underground construction activities such as mining operations.
The secant pile consists of closely spaced bored cast-in-place piles that are connected together with a reinforced concrete wall. The wall consists of intersecting piles that are arranged alternately in groups with each group sloped forward toward its endpoint.
Steps involved in constructing Secant Pile Wall
Site preparation is the first step in building your new home. It involves removing any existing structures and trees that stand on the property, as well as preparing the site itself.
In order to ensure the safety of both you and your workers, it’s important to remove any obstructions from your property before construction begins. The more thorough you are about this process, the smoother your build will go.
Excavation and foundation
Excavation is the process of digging, removing, and transporting material from a hole in the ground. Excavation is done to create space for buildings, roads, canals, tunnels, and other facilities. Boring machines such as tunnel boring machines are sometimes used when rock is too hard to break with other methods such as blasting or fire-setting.
Excavators require different types of digging equipment at their disposal depending on the type of soil or rock that is to be removed. Trenchers can be used for deep excavations in soft earth where large quantities of sand need not be moved but must be removed quickly. Dump trucks are typically used for moving soil about on construction sites or transporting it away from the site when it has been excavated by another method; however, they are also useful for moving rocks around because they have strong lifting capacity and do not require many people to operate them – only one person can operate most dump trucks (and two can operate very large ones) so they do not need lots of workers like an auger would do.
Framing is the process of constructing a secant pile wall, which is constructed by drilling into the ground and filling the holes with concrete. The steel bars used to hold this concrete in place are called reinforcement. The reinforcement must be inserted at regular intervals throughout the construction process so that it does not come loose during or after pouring, causing structural damage.
Advantages of using Secant Pile Wall
Secant pile walls are an economical, time-efficient, and effective alternative to other types of retaining structures. Most importantly, they can be constructed quickly. Secant piles can be driven in a matter of hours, whereas conventional cast-in-place concrete walls may require weeks or even months to complete. As such, secant pile walls are also easier to maintain than other types of retaining structures. Should you need to make structural adjustments later on down the road (say if you didn’t build your wall tall enough), it will require less effort than if you had built with another kind of retaining wall system.
The ability to work in the soft ground makes secant pile walls unique as well; they don’t depend upon solid soil conditions like gravity walls do (that’s why gravity walls tend only to work on flat ground). In addition, since these types of barriers can withstand high pressures due to their design configuration (the diagonal lines give them strength), they’re able to be used in rocky areas that would normally require more expensive equipment or specialized labor because there aren’t any large rocks present at all during the construction time frame.

Disadvantages of using Secant Pile Wall
Secant pile walls are not cheap to build. The cost of materials and labor is high, making them an expensive option when compared to other types of retaining walls. Additionally, constructing a secant pile wall requires specialized equipment that most contractors do not have access to. This makes it difficult to find contractors who can build this type of retaining wall at an affordable price point.
Another disadvantage of using secant pile walls is their long construction time. Secants can take weeks or months longer than other types of retaining walls, depending on the size and complexity of your project’s design specifications.
Cost of Secant Pile Wall
The cost of a secant pile wall depends on several factors: the type of soil, the size of the wall, how many piles are used, and what material you choose for it.
For example, if you want to build a small sectional retaining wall in sandy soil, you can use a pneumatic excavator and dig trenches from both sides. Then place steel H-piles into those trenches so that they are perpendicular to each other at 90-degree angles. After placing all four piles into their designated spots (two on each side), you’ll attach cross braces between them to create an X-shaped pattern that holds each individual pile together as well as helps keep your entire structure stable during earthquakes or heavy rains. You’ll then cover these steel H-piles with stone or concrete blocks until they’re completely filled up with dirt; this process will take several hours depending on how big your project is going to be overall.
The material cost of Secant Pile Wall
- The material cost of a secant pile wall is higher than the cost of any other retaining wall.
- The material cost of a secant pile wall is also higher than the cost of constructing a gravity wall.
The reason behind this is that the materials used in constructing such walls are comparatively expensive and it demands high installation costs as well.
The labor cost of Secant Pile Wall
Secant pile wall is an effective way of creating a solid foundation for a building or structure. However, the labor cost of a secant pile wall depends on various factors. For example, if you are constructing this type of foundation using steel pipes and will be paying high prices for it, then the labor cost is going to be higher than if you use cheaper materials like concrete or timber. Similarly, the size and location of your project will also factor into determining what your total labor cost will be. If a large area needs to be dug up in order to create space for an underground storage tank (UST) then more workers will have to be hired over time because they need more time and effort to complete their tasks correctly. Finally, experience and expertise matter when it comes down to calculating how much money should go towards hiring laborers who know exactly what needs to be done during each step of the construction process so that everything ends up being done correctly without issue later on down the road when someone tries using facility/building that hasn’t been fully finished yet because there was some sort mistake made earlier on when digging beneath ground level during initial stages where there wasn’t enough information available yet about what kind material needed digging beforehand so there weren’t any surprises later down the road after excavation work had already begun
Materials needed for Secant Pile Wall
To build a secant pile wall, you’ll need:
- Concrete – the primary material that makes up the majority of the secant pile wall.
- Steel reinforcement – used to reinforce concrete to make it stronger and more durable.
- Cement – is used in conjunction with water to create concrete.
- Sand – helps to fill gaps between rocks or other pieces in order to give them weight and stability when buried underground.
Benefits of Secant Pile Wall
The Secant Pile Wall is a cost-effective solution for retaining walls, embankments, and dewatering systems. Its flexibility allows the design to be customized to your needs, enabling it to be used for a wide range of applications. It can be used for retaining structures like bridges, tunnels, or any other large structure that requires extensive support but only over a short length of time. For example: In order for engineers to build a bridge across two hillsides they will need to excavate on one side and fill on another simultaneously so as not to create too much strain on either side of their structure. This technique is known as the “secant pile wall”.
Maintenance tips for Secant Pile Wall
- Maintain a clean structure.
- Seal the walls to prevent water from seeping through them and causing problems with your structure.
- Keep debris off of the wall surface, as it can cause damage or become lodged in an opening, which will cause an issue with drainage and other factors of the wall’s integrity.
- Maintain the slope of the ground around the structure so that water flows away from it easily and doesn’t pool up against its base
Secant Pile Wall is a bored cast-in-place reinforced concrete type of retaining structure that can be made waterproof to eliminate seepage through it.
Secant Pile Wall is a type of retaining wall which is constructed adjacent to each other. The main advantage of this type of retaining wall is the low cost compared to other types, such as gravity walls and cantilever walls. The main disadvantage is that due to their construction method, secant pile walls require more time for construction work than other types.
As mentioned earlier, Secant Pile Walls are made up of a large number of small-sized circular piles arranged at regular intervals along the length (or width) of a slope or embankment across which it must be built. These piles are installed diagonally into the ground with their upper end being anchored either by friction against the top surface (if soil conditions allow) or by means like tie bars fixed at the top surface which connect them together forming an interconnected network that resists earth pressures acting on these structures in a vertical direction (vertical stresses).
