Lake-adjacent sandy soil foundation pit slope construction method
The invention discloses a lake-adjacent sandy soil foundation pit slope construction method, and belongs to the field of foundation pit construction. The construction method comprises the steps that S1, basement foundation pit sandy soil earthwork is excavated to reach the lake water plane elevation; S2, a row of 18 # I-shaped steel is arranged on the periphery of a basement foundation pit at the interval of 300 mm, and the I-shaped steel extends into the bottom of the basement foundation pit by 2 m; S3, a sandy soil side slope above the lake water plane is made into a gradient of 1: 1, C25 fine aggregate concrete is sprayed with the thickness of 60 mm, and meshes with diameter phi 6.5 reinforcing steel bars and the interval of 250 are arranged inside the concrete for cooperation; and S4, remaining earthwork of the basement foundation pit is excavated, M5 cement mortar with the thickness of 40 mm is sprayed between the I-shaped steel, and meshes with diameter phi 4 reinforcing steel bars and the interval of 100 are arranged inside the mortar for cooperation. The safety hidden danger of sandy soil foundation pit slope collapse can be eliminated at a time, safety accidents caused by foundation pit slope collapse are completely eradicated, the safety of building constructors in a foundation pit is guaranteed, and therefore the purpose that the whole building system engineering is safe and free of accidents is achieved, the purpose of deep foundation pit engineering construction safety of lake surrounding buildings is achieved, and good safety production atmosphere and social reputation are obtained.
本发明公开一种临湖砂性土基坑边坡施工方法，属基坑施工领域。包括：步骤一：将地下室基坑砂性土土方开挖至临湖水平面高程；步骤二：沿地下室基坑周边打一排18号工字钢间距300㎜，伸入地下室基坑底2m；步骤三：将临湖水平面以上的砂性土边坡做成1:1的坡度，并喷射60㎜厚C25细石混凝土，内配φ6.5钢筋@250网片；步骤四：开挖地下室基坑余下土方，并在工字钢之间喷射40㎜厚M5水泥砂浆，内配φ4钢筋@100网片。能一次性消除砂性土基坑边坡坍塌的安全隐患，杜绝因基坑边坡坍塌而造成安全事故的发生，保证了基坑内建筑施工人员的安全性，从而实现整个建筑系统工程安全无事故目标、达到环湖建筑深基坑工程施工安全目的，取得了良好的安全生产氛围和社会信誉。
