Prefabricated concrete foundation pit slope protection construction method
A precast concrete foundation pit slope protection construction method comprises the steps that a plurality of rectangular concrete precast slabs are poured in advance, a reinforcing mesh is arranged in each precast slab, four hanging rings are arranged at the four corresponding corners of the top face of each precast slab, and a plurality of anchor rod through holes perpendicular to the slab face of each precast slab are formed in each precast slab; the precast slabs are laid upwards row by row from the bottom of the foundation pit side slope, after laying of each row of precast slabs is completed, waterproof rubber strips are laid along the top edge of one row of precast slabs, then the next row of precast slabs are laid upwards, and after the precast slabs on one side slope are laid fully, anchor rods are driven into side slope soil in anchor rod through holes in each precast slab; and finally, waterproof rubber strips are embedded into vertical joints of the left and right adjacent prefabricated slabs, and foundation pit slope protection construction is completed. The slope protection construction speed is high, the prefabricated plates can be repeatedly used, and material waste is reduced.
一种预制混凝土基坑护坡施工方法，预先浇筑多个矩形的混凝土预制板，每块预制板内设钢筋网片，每块预制板顶面对应4个角设有4个吊环，每块预制板上设多个与预制板的板面垂直的锚杆通孔；从基坑边坡底部向上逐排铺设预制板，每排预制板铺设完成后，沿一排预制板的顶边铺设防水橡胶条，然后向上铺设下一排预制板，一面边坡上的预制板铺满后，在每块预制板上的锚杆通孔中向边坡土体中打入锚杆，最后在左右相邻的预制板竖向接缝中嵌入防水橡胶条，完成基坑护坡施工。本发明护坡施工速度快，预制板可重复使用，减少材料浪费。
