Construction method of retaining structure of support pile-basement exterior wall co-structure
The invention discloses a construction method of a retaining structure of a support pile-basement exterior wall co-structure. The construction method comprises the following steps: step 1, sequentially carrying out foundation pit excavation, pile-anchor support system construction, foundation pit bottom cushion layer construction, foundation raft plate and basement exterior wall pouring construction and bottom layer waterproof coiled material construction according to a conventional construction mode; 2, backfilling a bottom-layer fertilizer groove to a position below the bottom elevation of a bottom-layer top plate of the basement; thirdly, a first plain concrete layer is poured, a waterproof roll is laid to the position above the top elevation of a first top plate, then a first fat groove is backfilled to the position below the bottom elevation of the first top plate, the thickness and the elevation of the poured plain concrete layer are determined, and then the plain concrete layer corresponding to the first top plate is poured above backfilled soil; and the like. According to the method, the wall thickness can be reduced, the horizontal supporting component is free of formwork erecting and steel bar binding, construction is convenient and fast, the period is short, cost is low, and waterproof reliability is achieved.
本发明公开了一种支护桩—地下室外墙共构的挡土结构施工方法，步骤一：按常规施工方式依次进行基坑开挖、桩锚支护体系施工、基坑底部垫层施工、基础筏板和地下室外墙浇筑施工和底层防水卷材施工；步骤二：底层肥槽回填至地下室底层顶板底标高下方位置；步骤三：第一层素混凝土层浇筑，将防水卷材铺设至第一层顶板顶标高上方位置，再将第一层肥槽回填至第一层顶板底标高下方位置，确定浇筑素混凝土层的厚度和标高，然后在回填土上方浇筑与第一层顶板对应的素混凝土层；等。该方法可减小墙厚，对水平支撑构件免支模和免绑扎钢筋，施工便捷，周期短，成本低，防水可靠。
