Overview Piles are cylindrical members that penetrate deep into the soil or rock layer. The anti-slide pile in the slope treatment project transfers the slope thrust from the upper part…

[Abstract] Rotary drill is a pile foundation construction machine with a high degree of mechanization and intelligence, flexible walking and movement, and simple installation and alignment. With different drill bits…

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 determine the ultimate bearing capacity…

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 mainly refers to the horizontal…

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 pile body may have defects…

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 pile diameter is 120cm and…

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 characteristics of good pile…

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 such as scheme design, geological…

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 steeper than the slope designed…

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 the construction process. Once defective…

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 as municipal construction, highways and…

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). Compared with magmatic rock and…
