Prefabricated length-adjustable inner support structure of foundation pit and construction method thereof
The invention belongs to the technical field of underground foundation pit engineering, and particularly relates to a prefabricated length-adjustable inner support structure of a foundation pit and aconstruction method thereof. The prefabricated length-adjustable inner support structure comprises an enclosure structure and prefabricated supports, wherein a top beam is arranged on the top of the enclosure structure, a waist beam is arranged on the inner side of the enclosure structure, and the prefabricated supports are respectively supported between two opposite sides of the top beam as wellas between two opposite sides of the waist beam; embedded parts are embedded in the top beam or the waist beam, one end of each prefabricated support is connected with the embedded part on one side ofthe prefabricated support, and the other end of the prefabricated support is connected with the embedded part on one side of the prefabricated support through a telescopic structure; and a jack is further supported between the other end of the prefabricated support and the embedded part on one side of the prefabricated support, and the jack is electrically connected with a control system. According to the prefabricated length-adjustable inner support structure, the length of an end connector can be adjusted through the telescopic structure, so that the construction error is adjusted; and additionally, the requirements of loss of prestress and repeated loading caused by support relaxation can be met.
本发明属于地下基坑工程技术领域，具体涉及一种装配式基坑可调节长度内支撑结构及其施工方法，包括包括围护结构和装配式支撑；所述围护结构的顶部设有冠梁，所述围护结构的内侧设有腰梁，所述冠梁相对的两侧之间以及所述腰梁相对的两侧之间均支撑有所述装配式支撑；所述冠梁或所述腰梁内均预埋有预埋件，所述装配式支撑的一端与其一侧的预埋件连接，所述装配式支撑的另一端与其一侧的预埋件通过可伸缩结构连接；且所述装配式支撑的另一端与其一侧的预埋件之间还支撑有千斤顶，所述千斤顶与控制系统电连接。本发明不仅可以通过可伸缩结构调节端部接头长度，从而调整施工误差；同时还可以满足预应力损失以及支撑松弛需要重复加载的需求。
