Slope protection soil consolidation construction process
The invention discloses a slope protection soil body consolidation construction process, which belongs to the field of slope support construction, and comprises the following steps: during foundation pit construction, excavating in sections and layers from top to bottom to form a working surface, manually finishing a slope surface, and then carrying out soil nailing, grouting, drainage hole, surface layer net hanging and tying, surface layer concrete spraying and other processes twice to carry out effective combined construction. It is ensured that soil in the foundation pit slope is effectively consolidated, and meanwhile the soil and the slope excavation face form a whole. According to the method, sinking and collapsing of soil bodies in the side slope caused by infiltration and scouring of surface water can be effectively avoided, the shielding effect of a waterproof curtain is achieved, and therefore the construction safety of a foundation pit is guaranteed.
本发明公开了一种护坡土体固结施工工艺，属于边坡支护施工领域，包括基坑施工时，自上而下分段、分层开挖形成工作面，人工修整坡面，然后分两次进行土钉、注浆、泄水孔、面层挂网拉结、面层混凝土喷射等工艺进行有效的结合施工，确保基坑边坡内的土体有效固结的同时，与边坡开挖面形成一个整体。本发明可以有效避免地表水的下渗冲刷，而造成边坡内土体的下陷坍塌，并起到止水帷幕的屏障作用，从而保证基坑的施工安全。
