Slope foundation pit supporting method
The invention discloses a slope foundation pit supporting method. The slope foundation pit supporting method comprises the following steps that S1, the depth of a foundation pit and the position of a slope are determined, holes are drilled in a road surface for many times, the depth of the holes is larger than that of the foundation pit, a reinforcement cage is arranged in each hole, concrete is poured into a concrete pile, and the part, higher than the ground, of the concrete pile is built with the concrete and steel bars; and S2, a foundation pit side slope is excavated through an excavator, soil nails are used for drilling holes in the side slope, the drilled soil nails are connected with spray irrigation concrete through steel bar sheets, and a soil nail wall is manufactured. The problems that an existing slope protection structure is a protection net, but the protection net is large in weight, wide in coverage area and large in gravel cleaning difficulty, falling stones cannot be cleaned out in time, a crown beam or the protection net is in a continuous stress state, large construction accidents are prone to being caused when the protection net is damaged, and therefore, a relatively large safety risk exists when a worker carries out construction at the bottom of the foundation pit are solved.
本发明公开了一种边坡基坑支护方法，包括如下步骤：S1、确定基坑深度及边坡位置，在路面上进行多次钻孔，孔的深度大于基坑深度，在每个孔内下钢筋笼并用混凝土浇筑成混凝土桩，所述混凝土桩高于地面的部分用混凝土及钢筋修筑；S2、使用挖掘机挖出基坑边坡，并在所述边坡上用土钉钻孔，将钻孔后的土钉用钢筋片连接喷灌混凝土并制成土钉墙。解决了现有的边坡防护结构都为防护网，但防护网重量较大、覆盖面积较广，同时碎石清理难度较大，导致不能将掉落的石块及时清理出去，这样导致冠梁或防护网处于持续受力的状态，当防护网一旦出现破损，容易造成较大的施工事故，导致工作人员在基坑底部进行施工时，存在着较大的安全风险的问题。
