Foundation pit top prefabricated retaining wall structure and construction method thereof
The invention belongs to the technical field of foundation pit engineering, and particularly relates to a foundation pit top prefabricated retaining wall structure and a construction method thereof. The foundation pit top prefabricated retaining wall structure comprises a crown beam and a prefabricated retaining wall arranged on the crown beam, and a pouring hole penetrating through in the vertical direction is reserved in the prefabricated retaining wall; a reserved steel bar is reserved at the top of the crown beam, the reserved steel bar partially extends out of the crown beam, and the part, extending out of the crown beam, of the reserved steel bar is inserted into the pouring hole; a nut is installed at the top end of the part, extending into the pouring hole, of the reserved steel bar; and fine stone micro-expansion concrete is poured in the pouring hole. The retaining wall is spliced on site in a prefabricated mode, the construction is convenient and fast, economical and environmental-friendly, and the construction efficiency can be improved; and the reserved steel bar is reserved at the top of the crown beam and the pouring hole is reserved in the prefabricated retaining wall in the early stage, the reserved steel bar is inserted into the pouring hole during assembly, the pouring hole is poured with the fine stone micro-expansion concrete in the later stage, then the retaining wall and the crown beam are connected into a whole, and the integrity and the connecting joint strength of the prefabricated retaining wall structure are improved.
本发明属于基坑工程技术领域，具体涉及一种基坑顶预制装配式挡土墙结构及其施工方法，包括冠梁以及设置于冠梁上的预制挡土墙，预制挡土墙上预留有沿竖向贯穿的灌注孔；冠梁的顶部预留有预留钢筋，预留钢筋部分伸至冠梁外，且预留钢筋伸至冠梁外的部分插入至灌注孔中；预留钢筋伸至灌注孔中的部分的顶端安装有螺帽；灌注孔内浇筑有细石微膨胀混凝土。本发明的挡土墙采用预制方式现场拼接，施工便捷、经济环保，还能提高施工效率；且通过前期在冠梁的顶部预留预留钢筋和在预制挡土墙上预留灌注孔，装配时将预留钢筋插入灌注孔内，后期用细石微膨胀混凝土灌注灌注孔后使挡土墙与冠梁连成整体，提高装配式挡土墙结构的整体性及连接节点强度。
