Foundation pit support structure and construction method thereof
The invention discloses a foundation pit support structure and a construction method thereof, and belongs to the field of building foundation structure design and construction. The foundation pit support structure is used for supporting, retaining, reinforcing and protecting a building foundation pit and comprises cast-in-place piles and top beams, the multiple cast-in-place piles are arranged on the side walls of the periphery of the building foundation pit respectively, the top beams are arranged on the tops of the cast-in-place piles, and the foundation pit support structure further comprises water stop plates and anchor cables; a water stop plate is arranged between every two cast-in-place piles, the connecting positions of the water stop plates and the cast-in-place piles are sealed, and all the water stop plates and the cast-in-place piles define a water stop curtain surrounding the building foundation pit. The anchor cables obliquely and downwards penetrate through the top beam from the upper side of the top beam and penetrate into the ground surface on the outer side of the building foundation pit, the included angle between each anchor cable and the corresponding cast-in-place pile is not smaller than 15 degrees, and the multiple anchor cables are arranged around the building foundation pit. The foundation pit support structure provided by the invention has the advantages of relatively few construction procedures, simple process, relatively shortened building construction period, quicker construction progress and low cost, and is not easy to cause quality problems.
本发明公开了一种基坑围护结构及其施工方法，属于建筑基础结构设计和施工领域；该基坑围护结构用于建筑基坑的支挡、加固与保护，包括灌注桩和冠梁，所述建筑基坑的四周侧壁分别排布多根灌注桩，所述灌注桩的顶部设置冠梁，其还包括止水板和锚索；所述灌注桩两两之间设置止水板，且止水板与灌注桩连接处密封，所有止水板与灌注桩围成包围建筑基坑的止水帷幕；所述锚索由冠梁上侧倾斜向下穿过冠梁并深入建筑基坑外侧的地表，锚索与灌注桩之间夹角不小于15°，围绕建筑基坑设置若干锚索；本发明提供的基坑围护结构施工工序相对较少，工艺简单，建筑施工周期相对缩短，施工进度更快，造价也能得到一定降低，也不容易引发质量问题。
