Construction method of piled raft basement tower crane foundation structure
The invention relates to a construction method of a piled raft basement tower crane foundation structure, which comprises the following steps: step 1, measuring and calculating the position of a tower crane, and delineating the arrangement position; step 2, excavating earthwork of a raft, a tower crane foundation and a pile cap; thirdly, an upper bearing platform column is installed on the bottom face of the pile bearing platform; fourthly, a raft plate is poured, and then a foundation cushion layer of the pile cap is poured; fifthly, waterproof coiled materials are laid on the foundation cushion layer; sixthly, a raft plate top face is arranged on the upper portion of the raft plate, raft plate reinforcing steel bars extending out of the raft plate top face are arranged on the raft plate, and the raft plate reinforcing steel bars are in butt joint with the pile cap reinforcing steel bars; seventhly, a water stop steel plate is welded to one side of the raft, and a plurality of tower crane embedded bolts are embedded in the tower crane foundation; and 8, the whole device is subjected to concrete pouring, so that the whole device is formed. According to the method, independent foundation dismantling work is avoided, the working coverage range of the tower crane is widened, and the characteristics of structural pile bearing platforms, raft stress and the like are effectively utilized.
本发明涉及一种桩筏地下室塔吊基础结构的施工方法，包括以下步骤：步骤一：对塔吊位置进行测量计算，并圈定布置位置：步骤二：对筏板、塔吊基础和桩承台的土方进行挖掘；步骤三：在桩承台底面上安装上承台柱；步骤四：浇筑筏板，完成后浇筑桩承台的基础垫层；步骤五：在基础垫层上铺设防水卷材；步骤六：将筏板上部设置有筏板顶面，筏板上设置有伸出筏板顶面的筏板钢筋，筏板钢筋与桩承台钢筋进行对接；步骤七：将止水钢板焊接在筏板的一侧上，在塔吊基础上埋入若干个塔吊预埋螺栓；步骤八：对整个装置进行混凝土浇筑，使得整体成型。本发明避免了独立基础拆除工作，提高了塔吊工作覆盖范围，有效利用结构桩承台、筏板受力等特点。
