The role of steel sheet pile pillars:
Steel sheet pile pillars are usually used in projects such as earthwork support, foundation reinforcement and river embankment reinforcement. In terms of earthwork support, steel sheet pile pillars can effectively control the lateral displacement and deformation of the earthwork and ensure the stability and safety of the earthwork. In terms of foundation reinforcement, steel sheet pile pillars can increase the bearing capacity of the foundation, avoid foundation settlement and damage, and thus ensure the safety of the building. In terms of river embankment reinforcement, steel sheet pile pillars can enhance the stability of the river bank and protect the river embankment from water erosion.
Advantages of steel sheet pile pillars:
Steel sheet pile pillars have the following advantages:
1. Easy installation: Steel sheet pile pillars are simple and convenient to install and can be completed in a shorter time.
2. Cost saving: The cost of steel sheet pile pillars is relatively low, which can save engineering costs.
3. Easy maintenance: Steel sheet pile pillars are not easy to rust or corrode, have a long service life, and are easy to maintain.
4. Environmental protection and energy saving: Steel sheet pile pillars can be recycled and reused, which is in line with the concept of environmental protection and energy saving.
What are the dangers of steel sheet pile support tilting?
Steel sheet pile support tilting exceeding plus or minus 2% is dangerous. The reasons include deformation of steel sheet piles, ground collapse, and fracture risk.
1. Steel sheet pile deformation: When the inclination of the steel sheet pile support system exceeds plus or minus 2%, it will cause deformation of the steel sheet piles, resulting in a decrease in the bearing capacity of the steel sheet piles, thereby affecting the stability of the support system
2. Ground collapse: When the support inclination exceeds plus or minus 2%, the ground will sink or collapse, further destroying the stability of the support system and even causing accidents.
3. Fracture risk: When the inclination of the steel sheet pile support system exceeds plus or minus 2%, the risk of fracture of the steel sheet piles will increase due to the bending and shear forces on the steel sheet piles, further affecting the safety and stability of the entire support system.
How to deal with the crooked pillars of steel sheet piles?
The reasons for the crooked pillars of steel sheet piles may include softening of the soil layer, excessive vibration, and damage to the pile body. In response to this situation, the following treatment methods can be adopted:
1. Re-pile: If the skewness is not serious, you can choose to fine-tune it, re-tamp the pile head, straighten the steel sheet pile, etc., to ensure that it meets the design requirements. If the skewness is serious, you need to re-pile and choose a suitable method to reinstall it.
2. Reinforcement: For slightly skewed steel sheet piles, reinforcement methods can be used to increase their stability. This can be done by drilling drilling glue into the side for sealing, or adding drainage pipes around the pile foundation to improve the drainage of the soil.
3. Lengthen: If the skewness is serious, you can extend or continue by adding a connecting plate to the upper end of the steel sheet pile, and use steel plates for reinforcement to ensure its stability.
In addition, for the steel sheet piles used for the second time, damage or deformation may occur. Here are some correction methods:
Correct the distortion of the steel sheet pile: fix the steel sheet pile on the support point, and use a jack to push the convex part of the steel sheet pile for cold bending correction. Lateral bending correction is usually carried out on a special correction platform.
Repair the surface defects of the steel sheet pile: first clean the rust and oil stains near the defect, then use welding repair method to fill it, and then use a grinding wheel to grind it.
Correct the deformation of the lock of the steel sheet pile: use the standard steel sheet pile as the lock shaping mold, use a slow winch to pull and adjust it, or use oxyacetylene hot baking and a sledgehammer to knock the mold to push it for straightening.
Correct the end plane of the steel sheet pile: use oxyacetylene to cut part of the pile end so that the end plane is perpendicular to the axis, and then use a grinding wheel to grind and trim the cut surface.
Correct the local deformation of the steel sheet pile: use oxyacetylene hot baking combined with jack top pressure and sledgehammer knocking to correct the local deformation.
Scope of application of steel sheet pile pillars:
Steel sheet pile pillars are suitable for the following projects:
1. Earthwork support: Steel sheet pile pillars can be used in retaining walls, foundation pit support, slope reinforcement and other projects.
2. Foundation reinforcement: Steel sheet pile pillars can be used in projects such as foundation reinforcement, pile foundation reinforcement and bridge foundation reinforcement.
3. River embankment reinforcement: Steel sheet pile pillars can be used in projects such as river embankment reinforcement, dam reinforcement and flood control projects.
