Early backfilling method for foundation pit fat groove
The invention relates to the technical field of foundation pit construction, in particular to an advanced backfilling method for a foundation pit fat groove. Comprising the steps of designing profile steel and head plates according to a force transmission value of a horizontal load of the post-cast strip; the profile steel and the end sealing plate are processed and manufactured according to corresponding specifications and sizes; constructing a main body structure on one side of the post-cast strip; the profile steel is installed and constructed at the post-cast strip; constructing a main body structure on the other side of the post-cast strip; waterproof construction of the basement exterior wall; backfilling a foundation pit fat groove; the two ends of the profile steel are not fixedly connected with the two sides of the rear adhesive tape, end sealing plate contact faces are arranged on the sections of the two sides of the post-cast strip, and the two ends of the profile steel abut against the sections of the two sides of the post-cast strip through end sealing plates respectively. The two ends of the added profile steel are not fixedly connected with the post-cast strip structure, and compared with a traditional method that the two ends of the profile steel are embedded into structures on the two sides of the post-cast strip, the profile steel fracture or post-cast strip damage caused by the height difference caused by sedimentation is avoided. In this way, compared with traditional foundation pit fat groove backfilling, the profile steel arrangement method is more suitable for deep foundation pit fat grooves.
本发明涉及基坑施工技术领域，是一种基坑肥槽的提前回填方法；包括根据后浇带水平荷载的传力值设计型钢和封头板；型钢、封头板照相应规格尺寸加工制作；后浇带一侧主体结构施工；型钢在后浇带处安装施工；后浇带另一侧主体结构施工；地下室外墙防水施工；基坑肥槽回填；型钢的两端与后胶带两侧均不固定连接，在后浇带的两侧断面处设置封头板接触面，型钢的两端通过封头板而分别抵住后浇带两侧断面。本发明所增设的型钢，两端与后浇带结构并不固定连接，与相对传统型钢将两端部埋入后浇带两侧结构中的做法相比，避免了沉降导致的高差引起的型钢断裂或后浇带破损。如此相比于传统基坑肥槽回填，本发明提出的型钢设置方法更适用于深基坑肥槽。
