To ensure that there is no slurry leakage during the construction of bored piles in karst development areas, or that there is no slurry leakage

Common problem one: soil (gray soil) piles are not dense and broken Phenomenon: The backfilling of the pile holes is uneven, the ramming is not

Building pile foundation projects have many construction procedures and high process requirements. Many factors affect the quality of pile foundations. Generally, they include insufficient detailed

Building Foundation Design Specification 1. The center distance of friction piles should not be less than 3 times the diameter of the pile body; the

Insufficient Torque of Power Head of Rotary Drilling Rig Fault phenomenon: The power head torque of the rotary drilling rig is insufficient during drilling construction,

After the bored piles are poured into piles, occasionally the pile length is shorter than the designed length. How do you deal with this situation?

The function of the pile is to transfer the load of the upper building to the deep soil (rock) layer with a strong bearing capacity

Steel sheet pile cofferdams are suitable for basic projects such as sandy soil, gravel soil, semi-dry clay, weathered rock formations, etc. with water depths above

Pile Foundation Classification and Construction Principles 1. Classification According to Load-Bearing Piles ① Friction type pile: Friction pile: Under the limited state of bearing capacity,

Soil nail support is a new type of retaining structure developed in recent years for soil excavation and slope stabilization. It has been rapidly popularized

The four major construction technologies are dry hole forming technology, slurry static pressure technology, casing technology, and concrete wall-making technology. The rotary drilling rig is

    Bored cast-in-place piles have the advantages of low construction noise, and low vibration, pile length and diameter can be freely changed according to
