Drainage flow rate control system of foundation pit support structure and drainage method of drainage flow rate control system
The invention discloses a drainage flow speed control system of a foundation pit support structure and a drainage method of the drainage flow speed control system, and the drainage flow speed control system comprises at least one drainage pipe which is close to a bottom plate of a building in a pit, is inserted into a gap between the foundation pit support structure and the building in the pit, and is positioned on the foundation pit support structure; the drainage tube comprises a flow speed control tube section and linear conversion tube sections communicated with the two ends of the flow speed control tube section, the flow speed control tube section is formed by connecting a plurality of sections of sleeves in a sleeved mode, and the plurality of sections of sleeves comprise a plurality of sections of b-shaped sleeves and a plurality of sections of d-shaped sleeves which are connected in a sleeved mode. The adjacent b-shaped casing pipes and d-shaped casing pipes are alternately distributed in a positive and negative inclination angle mode and are communicated, the flow velocity is a first flow velocity when the drainage pipes are inserted into the foundation pit support structure in the forward direction, the flow velocity is a second flow velocity when the drainage pipes are inserted into the foundation pit support structure in the reverse direction, and the second flow velocity is smaller than the first flow velocity. According to the method, the foundation pit support structure can be slowly drained into the foundation pit, and the safety of the foundation pit support structure and buildings in the pit is guaranteed.
本发明公开一种基坑围护结构的排水流速控制系统及其排水方法，该排水流速控制系统包括靠近坑内建筑的底板插入在基坑围护结构上位于其与坑内建筑之间的间隙内的至少一根引流管，所述引流管包括流速控制管段及连通在所述流速控制管段两端的直线转换管段，所述流速控制管段由若干节套管套接组成，若干节套管包括相互套接的多节b字形套管和多节d字形套管，相邻所述b字形套管和d字形套管正反倾角交替分布且连通，所述引流管正向插入在基坑围护结构上时为第一流速，所述引流管反向插入在基坑围护结构上时为第二流速，所述第二流速小于第一流速。本发明能够对基坑围护结构进行缓慢地排水至基坑内，保障基坑围护结构及坑内建筑的安全。
