During pipe jacking construction, in addition to overcoming the resistance at the front, there is also the need to overcome significant frictional resistance. Grouting technology is commonly used in engineering to reduce the frictional resistance exe...
In the installation of pre-bored grouted planted (PGP) piles and other composite pile foundations, cement is commonly used in the grouting stage. However, the cement-production process generates significant CO2 emissions, which are not favorable for...
Grouting reinforcement plays an important role in repairing fractures and improving the strength of the surrounding rock. To address practical engineering challenges such as caving and chip off-falling of surrounding rock in deep roadways, normal spl...
To investigate the bearing characteristics of super-long and large-diameter cast-in-place piles with combined pile-end and pile-side post-grouting, double-load-box self-balanced static-load tests were conducted on two such piles of the Yellow River B...
To enhance the uplift resistance of micropiles used in soil slope reinforcement and ensure the stability and safety of slope structures, a novel micropile incorporating a small-scale pneumatic device and anchorage components was developed, and its up...
This paper presents a novel design for uplift piles incorporating a composite-anchor system. The composite-anchor system consists of steel strands, a non-expansion grouting body, and a high-strength steel pile. The aim of this design is to enhance th...
Reinforced composite prestressed concrete hollow square (RCPHS) piles, installed through pre-drilling, grouting, and static jacking, integrate the large lateral contact area of cement–soil casings with the high strength and stiffness of prestre...
