Construction method of foundation pit slope excavation and supporting structure
The invention relates to the field of foundation pit side slopes, in particular to a construction method of a foundation pit side slope excavation and supporting structure. A construction method of a foundation pit slope excavation and supporting structure comprises the following steps that firstly, foundation pit excavation is conducted for the first time in a specified area, and excavation is conducted to the specified depth; (2) a walking plate for passing is arranged along the slope surface, and the walking plate is fixed in a slope soil body through a fixing assembly; (3) a flexible slope protection net is arranged between every two adjacent walking plates; (4) a line needing piling and supporting is arranged in the first foundation pit; (5) the support piles are driven according to the well-placed lines; (6) the manufactured reinforcement cage is placed in the pile core of the support pile, and grouting is conducted in the pile core; and (7) earth in the foundation pit is excavated and transported away, and then multiple times of longitudinal deep excavation are conducted till the earth is excavated to the designated depth. The device has the effect that construction workers can conveniently move from the interior of a foundation pit to the ground.
本申请涉及基坑边坡领域，更具体地说，它涉及一种基坑边坡开挖及支护结构的施工方法。一种基坑边坡开挖及支护结构的施工方法，包括以下步骤：步骤1)：在规定区域内进行第一次基坑开挖，开挖至指定深度；步骤2)：沿着坡面设置供通行的行走板，行走板通过固定组件固定在边坡土体内；步骤3)：在相邻的行走板间设置柔性边坡防护网；步骤4)：在第一次基坑内设置需要打桩支护的线；步骤5)：根据放好的线打入支护桩；步骤6)：把制作好的钢筋笼放入支护桩的桩芯内，往桩芯内注浆；步骤7)：将基坑内的土方开挖、运走，然后进行多次纵深开挖，直至开挖到指定深度。本申请具有便于施工工人在基坑内到地面之间移动的效果。
