Construction method of deep foundation pit under high slope condition
The invention discloses a construction method of a deep foundation pit under a high slope condition. The construction method comprises the following steps: (1) constructing a construction road; (2) steel pipe piles are constructed at the high slope; (3) earth excavation is conducted in the foundation pit from top to bottom in a segmented mode, the first segment of earth is directly excavated, and excavation of the other segments of earth needs to be completed through supporting construction of the previous segment and is qualified through detection; (4) after the earthwork of the section is excavated, concrete is sprayed on the surface of the soil body for surface protection; (5) performing soil nail construction in the soil layer; (6) constructing a hanging net and spraying concrete on the surface of the concrete pavement; (7) steel bars are bound on the inner side of the hanging net sprayed concrete; (8) erecting a template; (9) concrete is poured, and supporting construction of the section is completed; (10) repeating the steps (3)-(9) until the bottom of the foundation pit is constructed; and (11) bottom plate reinforcing steel bar binding and bottom plate concrete pouring are conducted. The supporting structure is reasonable in design, simple in construction step, large in supporting depth and good in using effect, and belongs to the technical field of foundation pit construction.
一种高边坡条件下深基坑的施工方法，(1)施工便道的施工；(2)在高边坡处，进行钢管桩的施工；(3)在基坑内从上往下分节进行土方开挖，第一节土方直接开挖，其余节土方的开挖需上一节的支护施工完成并经检测合格；(4)开挖本节土方后，土体表面喷射混凝土护面；(5)向土层内进行土钉施工；(6)在混凝土护面表面施工挂网喷射混凝土；(7)在挂网喷射混凝土的内侧绑扎钢筋；(8)模板搭设；(9)混凝土浇筑，完成本节的支护施工；(10)重复步骤(3)‑(9)，直至施工到基坑底；(11)底板钢筋绑扎和底板混凝土浇筑。本发明支护结构设计合理、施工步骤简单、支护深度大、使用效果好，属于基坑施工技术领域。
