Construction method for supporting foundation pit adjacent to building and mountainous region
The invention discloses a construction method for supporting a foundation pit adjacent to a building and a mountainous region. The construction method comprises the following steps of: 1) carrying out earth excavation by utilizing an excavator, and trimming a side slope according to a ratio of 1 to 1; 2) drilling a hole in a foundation pit protection slope by adopting a rivet drilling machine, finishing the hole and inspecting the hole; and 3) arranging soil nails and prestressed anchor cables, grouting, mounting a reinforcing mesh, and spraying slurry to form a composite soil nail wall. According to the construction method, the composite soil nail wall with multiple soil nails and three prestressed anchor cables is adopted for supporting, so that the construction efficiency is high, and the safety coefficient is high; and meanwhile, the supporting scheme further considers the drainage problem, a drainage ditch and a water collecting pit are arranged, so that rainwater is prevented from flowing into the foundation pit, meanwhile, the seeping water is discharged, and the stability of the surrounding soil body is guaranteed.
本发明公布了一种建筑物与山地相临的基坑支护施工方法，步骤为：1)利用挖机进行土方开挖，按1:1修整边坡；2)采用锚钉钻机在基坑护坡钻孔、终孔并验孔；3)设置土钉、预应力锚索，注浆、安装钢筋网、喷浆成复合土钉墙。本发明通过采用多道土钉加三道预应力锚索的复合土钉墙进行支护，施工效率高，安全系数高，同时本发明的支护方案还考虑了排水问题，通过设置排水沟以及集水坑，来避免雨水流入基坑，同时将渗出的水排出，保证了周围土体的稳定性。
