抗拔抗压灌注桩分层环形密集孔后注浆施工方法
By setting grouting pipes at the pile bottom and pile side on the reinforcing cage, and combining them with layered annular dense hole grouting through annular grouting pipes, the problems of cumbersome construction and uneven grouting in the existing technology are solved, thereby improving the bearing capacity and construction efficiency of the pull-out and compressive cast-in-place piles.

AI Technical Summary
In existing technologies, post-pile grouting is a complicated construction process with uneven grouting effect, which affects the bearing capacity of pull-out and compressive cast-in-place piles.
Grouting pipes at the bottom and sides of the pile are installed on the reinforcing cage. The bottom of the grouting pipes on the sides of the pile is connected to a ring-shaped grouting pipe. After the concrete is poured, layered ring-shaped dense hole grouting is carried out through these grouting pipes to improve the permeability, filling, compaction and consolidation of the bearing layer, sediment layer and soil on the side of the pile.
It improves the bearing capacity of a single pile, facilitates and speeds up construction, ensures uniform grout distribution, and enhances construction efficiency.
