Deep foundation pit soil and stone excavation and slope support construction method
The invention discloses a deep foundation pit earth-rock excavation and slope support construction method, which relates to the technical field of deep foundation pit excavation, and comprises the following steps: step 1, preparation before construction: making a measurement scheme, and determining a deep foundation pit excavation sideline, a foundation pit grading sideline and a soil layer excavation elevation; 2, excavation of earth and stone of the foundation pit, wherein the foundation pit is excavated in a layered mode from top to bottom by adopting a multi-layer transverse full-width and strip channel longitudinal matched excavation mode; thirdly, foundation pit drainage is conducted, and in the foundation pit excavation process and the bottom plate construction process, open trench drainage and concentrated water pumping modes are adopted; and fourthly, foundation pit slope protection construction is conducted, specifically, rock slopes with the elevation below 100 m are subjected to direct shotcrete anchor protection, and temporary soil slopes are subjected to hanging net shotcrete anchor protection. According to the construction method, the excavation area of the foundation pit is partitioned, construction can be conducted in multiple areas at the same time, the construction progress can be improved, the use stage of each construction mechanical device can be planned reasonably, and the construction period is shortened.
本发明公开了深基坑土石开挖及边坡支护施工方法，涉及深基坑开挖技术领域，包括步骤一、施工前准备：制定测量方案，确定深基坑开挖边线、基坑分级边线和土层开挖标高；步骤二、基坑土石方开挖：基坑采用多层横向全宽和分条带通道纵向配合开挖方式由上至下分层开挖；步骤三、基坑排水：在基坑开挖及底板施工时采用明沟排水和集中抽水的方式；步骤四、基坑边坡防护施工：高程100m以下的岩质边坡直接喷锚防护，土质临时边坡采用挂网喷锚防护。本发明将基坑开挖的区域进行分区，能够多区域同时进行施工，有利于提高施工进程，并且有利于合理规划各个施工机械设备的使用阶段，缩短工期。
