Construction method for shallow foundation pit slope toe support in narrow area
The invention discloses a construction method for a shallow foundation pit slope toe support in a narrow area, and belongs to the field of foundation pit support engineering construction. Comprising the following steps: before foundation pit excavation construction, measuring and setting out a foundation pit excavation range; a foundation pit is excavated, specifically, the foundation pit is excavated downwards according to the designed required slope making coefficient till the designed elevation is excavated; the range of the minimum working face of the pit bottom is measured, lime is scattered, the slope toe within the range of the minimum working face is cut and dug by 3-5 m, timber piles with the length larger than 2 m are rapidly driven into the cut and dug slope toe edge by 3-5 m, and the interval between every two adjacent timber piles is 1 m; the transverse ridges are nailed on the baffles in advance and then inserted into the baffles, and after the timber piles and the baffles are installed on the periphery of the foundation pit, waterproof cloth is laid on the side slope; sandbags are pressed between the slope toe and the baffle, the stability of the side slope is further improved, follow-up construction needs to be rapidly carried out after the supporting work is completed, early backfilling is won, and safety is ensured. According to the construction method, the problem that the slope making coefficient cannot meet the requirement is solved, and the slope toe is reinforced and supported.
本发明公开了一种狭窄地区浅基坑坡脚支护的施工方法，属于基坑支护工程施工领域。包括以下步骤：在基坑开挖施工前，测量放线出基坑开挖范围；开挖基坑，按照设计的要求放坡系数向下开挖基坑，直至开挖的设计标高为止；测量出坑底最小工作面的范围，撒上白灰，将最小工作面范围内的坡脚切挖3‑5m长，迅速在切挖的3‑5m的坡脚边打入长2m以上的木桩，木桩间距1m/根；提前将横楞钉在挡板上，后插入挡板，基坑一周全部安装完成木桩及挡板后，在边坡上铺上雨布；在坡脚与挡板之间压上沙袋，进一步增加边坡的稳定性，上述支护工作完成后应当迅速开展后续施工，争取早日回填，确保安全。本发明解决了因放坡系数无法满足要求，所设计对坡脚增强支护的施工方法。
