Continuous foundation pit waist beam and construction method thereof
The invention relates to a continuous foundation pit waist beam and a construction method thereof, and belongs to the field of foundation pit side wall support. The continuous foundation pit waist beam comprises multiple sections of steel waist beams, concrete pouring bodies and connecting pieces, wherein the multiple sections of steel waist beams are anchored on the side wall of a foundation pitand are arranged in sequence in the length direction of the side wall of the foundation pit; the concrete pouring bodies are prefabricated on the side wall of the foundation pit and are arranged between every two adjacent sections of steel waist beams; and two groups of connecting pieces are detachably arranged between the concrete pouring bodies and the steel waist beams respectively, so that theconnection of every two adjacent sections of steel waist beams is realized. The concrete pouring bodies are arranged between every two adjacent steel waist beams, and the connecting pieces are detachably connected between the concrete pouring bodies and the steel waist beams, so that the integrity between the steel waist beams is increased, and the support effect of the waist beam is increased; and additionally, the steel waist beams can be conveniently removed in the later period, the temporary support effect of the foundation pit is achieved, and the purpose of increasing the support effectof the waist beam on the side wall of the foundation pit on the premise that the waist beam is completely recycled when the waist beam is removed is achieved.
本申请为一种连续性基坑腰梁及其施工方法,属于基坑侧壁支护领域，包括锚固于基坑侧壁上的多段钢腰梁，多段钢腰梁沿基坑侧壁长度方向依次设置；混凝土浇筑体，混凝土浇筑体预制于基坑侧壁，且混凝土浇筑体设置于相邻两段钢腰梁之间；连接件，连接件设置两组，两组连接件分别可拆卸设置于混凝土浇筑体与钢腰梁之间，以实现相邻两段钢腰梁的连接；通过在相邻的两个钢腰梁之间设置混凝土浇筑体，并通过连接件可拆卸连接在混凝土浇筑体与钢腰梁之间，提高钢腰梁之间的整体性，提高腰梁的支护效果；同时方便后期拆除钢腰梁，实现基坑临时支护的效果，实现在拆除腰梁时保证腰梁的完整回收的前提下提高腰梁对基坑侧壁的支护效果的目的。
