Embodiment Construction
[0019] The height of each section of the anti-slide pile retaining wall is 1.5m, and the excavation depth is controlled at about 1.7m. figure 2 Among them, a bottomless formwork construction method for anti-slide pile concrete retaining wall, comprising the following steps:
[0020] 1. Welding and bundling steel bars under the poured retaining wall 1; figure 2 The reinforcing bars described in include vertical reinforcing bars 4 and transverse reinforcing bars, wherein the vertical reinforcing bars 4 protrude from the bottom of the pouring bin by a welding length. The vertical steel bars 4 protrude from the bottom 9-11d of the pouring bin, the optimal one is 10d, and the d is the diameter of the steel bar.
[0021] 2. Standing formwork, formwork 3 adopts P3015 formwork, the gaps of the formwork must be tightly connected, and rubber strips are added to the joints to stop water. A feed opening is left on the upper end of the template 3 for filling river sand and pouring conc...
