Support changing construction method of basement structure
The invention relates to a support changing construction method for a basement structure. The method comprises the following steps that S1, a basement outer wall and a structural floor plate are constructed; s2, the structural floor plate extends to the supporting pile, and the extending part forms a force transmission belt which is longitudinally and continuously long along the supporting pile; s3, when the force transmission belt is constructed, a plurality of reserved holes are formed in the force transmission belt; and S4, after the force transmission belt and the structural floor plate are maintained to reach the supporting strength, an upper inner support can be removed for support replacement operation, and the working procedures of formwork removal and cleaning, waterproof and waterproof protection layer backfilling, compactness detection and the like of the basement outer wall below the force transmission belt can be conducted through the reserved hole. After the force transmission belt and the structural floor plate are maintained to reach the supporting strength, support changing operation can be conducted by bypassing construction procedures such as basement outer wall maintenance, formwork removal, outer wall waterproofing, waterproof protection and earthwork backfilling, the construction time and the technical intermittent time are shortened to a great extent, and the construction progress of the deep foundation pit is effectively accelerated.
本发明涉及一种地下室结构的换撑施工方法，包括以下步骤：S1:施工地下室外墙和结构楼层板；S2:将结构楼层板延伸至支护桩，延伸部分形成一条沿支护桩纵向通长的传力带；S3:施工传力带时，传力带上设置若干预留洞口；S4:待传力带和结构楼层板养护达到支撑强度后，即可拆除上部内支撑进行换撑作业，并可以通过预留洞口下去进行传力带以下的地下室外墙的模板拆除清理、防水及防水保护层、土方回填及密实度检测等工序。本发明传力带和结构楼层板养护达到支撑强度后，可以先绕过地下室外墙的养护、拆除模板、外墙防水、防水保护及土方回填等施工工序进行换撑作业，很大程度缩短了施工时间和技术间歇时间，有效地加快了深基坑的施工进度。
