摘要
在东山供水工程施工二标输水洞施工过程中,由于出水量过大,喷射混凝土难以施工,在施工前预留了排水孔,但在混凝土衬砌前需要施以简单快捷的堵水方法对预留排水孔进行封堵。针对该状况,发明了一种堵水装置用于喷射混凝土预留孔的封堵。阐述了“螺栓橡胶封水塞”在输水隧洞预留排水孔封堵施工中的应用。
In the construction process of the second Bid water conveyance tunnel of Dongshan Water Supply Project,due to the excessive water output,it is difficult to construct with shotcrete.Although drainage holes are reserved before the construction,a simple and quick water blocking method is needed to block the reserved drainage holes before the concrete lining.According to this situation,a water blocking device is invented for blocking the reserved holes of shotcrete.This paper expounds the application of"bolt rubber water sealing plug"in the blocking construction of the reserved drainage hole of the water conveyance tunnel.
