Retaining wall steel bar of underground pipe gallery foundation pit slope protection project and construction method thereof
The invention relates to the field of pipe gallery foundation pit slope protection engineering construction, in particular to a retaining wall steel bar of underground pipe gallery foundation pit slope protection engineering and a construction method thereof. The retaining wall steel bar comprises at least two transverse positioning steel bars, at least two longitudinal positioning steel bars anda reinforcing mesh, wherein the axes of the transverse positioning steel bars are horizontal to the inter-pile soil and are fixedly arranged on the inter-pile soil at equal intervals along the axial direction through fastening joint bars, the axes of the longitudinal positioning steel bars are horizontal to the inter-pile soil, the longitudinal positioning steel bars and the transverse positioningsteel bars are perpendicular to each other and are fixedly arranged on the inter-pile soil at equal intervals in the axial direction through the fastening joint bars, cross joints of the transverse positioning steel bars and the longitudinal positioning steel bars are fixedly connected with the inter-pile soil through the fastening joint bars, the reinforcing mesh comprises longitudinal horizontal reinforcing steel bars and transverse horizontal reinforcing steel bars, the longitudinal horizontal reinforcing steel bars and the transverse horizontal reinforcing steel bars are arranged on the outer sides of the longitudinal positioning steel bars in a criss-cross mode, and cross points of the longitudinal horizontal reinforcing steel bars and the transverse horizontal reinforcing steel barsare bound and fixedly arranged on the inter-pile soil through the fastening joint bars. The retaining wall steel bar can prevent the reinforcing mesh from protruding or hollowing.
本发明涉及管廊基坑护坡工程施工领域，具体是涉及一种地下管廊基坑护坡工程的护壁钢筋及其施工方法，包括有：至少两根横向定位刚筋，横向定位刚筋轴线与桩间土水平通过紧固插筋沿轴向等间距固定设置在桩间土上；至少两根纵向定位刚筋，纵向定位刚筋轴线与桩间土水平且与横向定位刚筋垂直通过紧固插筋沿轴向等间距固定设置在桩间土上，横向定位刚筋和纵向定位刚筋交叉节由紧固插筋与桩间土固定连接；钢筋网片，包括有纵向水平钢筋和横向水平钢筋，纵向水平钢筋和横向水平钢筋纵横交错设置在纵向定位刚筋外侧，纵向水平钢筋和横向水平钢筋交叉点进行绑扎，钢筋网片交叉点通过紧固插筋固定设置在桩间土上，该护壁钢筋能够避免钢筋网片凸起或者空鼓。
