Pile foundation testing is divided into pre-construction and post-construction testing of pile foundations: before construction, test pile testing provides a basis for design, mainly to
As a foundation pit enclosure structure, the underground diaphragm wall is designed and calculated mainly based on three major aspects: strength, deformation, and stability. Strength
There are many types of pile foundations with large differences in construction techniques. In addition, the ground changes are complex. During the construction process, the
Bored Bite Pile Construction Method Bored interlocking piles are drilled into piles by rotary drilling. The piles are arranged to interlock with each other. The
The steel casing wall protection is used during the hole-forming process of the cast-in-place piles drilled by the full-casing and full-rotation drilling rig. It has
The safety and stability of the water-stop curtain have a significant impact on surrounding safety. In actual construction, loopholes may occur due to various factors
Earthworks 1. The excavation slope is too steep 1.1. Phenomenon: During earthwork excavation, the slope of the foundation pit and trench after excavation is often
During the construction of pile foundations, due to geographical environment, mechanical equipment, and human factors, it is inevitable that some defective piles will appear during
A rotary drilling rig is a construction machine suitable for hole-forming operations in construction foundation projects. It is widely used in foundation construction projects such
Rock Name (Origin) Different rock names represent their origin. The origin of rocks includes (magmatic rock (intrusive rock, volcanic rock), sedimentary rock, and metamorphic rock).
How to Prevent and Control Bored Piles from Deflecting? 1. Quality problems and phenomena 1) The hole is not vertical after being formed, and the
Due to the complex construction technology of bored pile engineering, various visible or invisible factors may interfere with the final pile quality during construction. To
