Drilling cast-in-place pile reinforcement mesh fixing structure and method
The invention discloses a drilling cast-in-place pile reinforcing mesh fixing structure and method. The structure comprises a plurality of transverse compression bars, a plurality of longitudinal compression bars, reinforcing mesh sheets, J-shaped anchor bars and fine aggregate concrete. The two ends of the transverse compression bars are implanted into slope protection piles, the plurality of longitudinal compression bars and the transverse compression bars are mutually crossed, welded and fixed, and the reinforcing mesh sheets are internally attached to the sides, facing inter-pile soil, onthe inner sides of the transverse compression bars and the longitudinal compression bars; long straight sections of the J-shaped anchor bars are implanted into the inter-pile soil, bent sections of the J-shaped anchor bars penetrate through the reinforcing mesh sheets and hook the transverse compression bars and the longitudinal compression bars, and implanting holes, where the J-shaped anchor bars are implanted, in the inter-pile soil are filled with mortar fixedly; and the fine aggregate concrete is sprayed to the sides, facing the interior of a foundation pit, on the outer sides of the transverse compression bars, the longitudinal compression bars and the reinforcing mesh sheets. The inter-pile support detailed node treatment can greatly improve the stability and safety of a pile foundation retaining wall, the inter-pile soil can be effectively fixed, and safety of foundation pit support and the overall stability of the foundation pit are ensured.
本发明公开了一种钻孔灌注桩钢筋网固定结构及固定方法，结构包括：多道横压筋，两端分别植入护坡桩；多道纵压筋，与横压筋相互交叉焊接固定；钢筋网片，内附于多道横压筋与多道纵压筋的内侧、面向桩间土体的一侧；J型锚筋，长直段植入桩间土体中，弯折段穿过钢筋网片并勾住横压筋与纵压筋，桩间土体中植入J型锚筋的植入孔内用砂浆填充固定；细石混凝土，喷注于横压筋、纵压筋和钢筋网片的外侧、面向基坑内的一侧。该桩间支护细部节点处理能够大大提升桩基护壁的稳定性与安全性，能够有效的固定桩间土，保证了基坑支护的安全及基坑的整体稳定性。
