Construction method of prefabricated spliced crown beam for foundation pit
The invention relates to the technical field of underground building construction, in particular to a construction method of a prefabricated spliced crown beam for a foundation pit. Comprising the following steps that S1, fender posts are driven, slope excavation is conducted on the outer sides of the fender posts, and the upper portions of the fender posts are exposed out of the ground; s2, prefabricated splicing top beams are installed on the tops of the fender posts; outer steel plates are arranged on the outer sides of the tops of the fender posts, inner steel plates are arranged on the inner sides of the tops of the fender posts, the outer steel plates and the inner steel plates are connected through pull rods, and the pull rods are located in gaps between every two adjacent fender posts; and S3, the top beam foundation pit is backfilled, and gaps between the fender posts are filled. The construction process is simple, the construction efficiency of the crown beam is improved, and the truss stress system realized at the crown beam can meet the functional requirements of the crown beam.
本发明涉及地下建筑施工技术领域，特别是一种基坑用预制拼接冠梁的施工方法。包括以下步骤：S1、打设围护桩，在围护桩的外侧进行放坡开挖，使围护桩的上部露出地面；S2、在围护桩的顶部进行预制拼接冠梁的安装；在围护桩的顶部外侧设置外侧钢板，围护桩的顶部内侧设置内侧钢板，外侧钢板和内侧钢板之间通过拉杆连接，拉杆位于相邻两围护桩的空隙内；S3、回填冠梁基坑，填充围护桩之间的空隙。施工工序简单，提高了冠梁的施工效率，其在冠梁处实现的桁架受力体系能够满足冠梁的功能需求。
