Dam face underwater repairing device and method
The invention discloses a dam face underwater repairing device. The dam face underwater repairing device comprises a construction bin and a man entering pipeline, the construction bin is a hollow cylinder with an opening in one face, the opening end of the construction bin faces the horizontal direction, a main water stop belt and an auxiliary water stop belt are sequentially arranged on the annular end face of the opening end of the construction bin from inside to outside, the outer edge of the auxiliary water stop belt exceeds the outer edge of the end face of the opening end of the construction bin, a water pumping hole and a manhole are formed in the side wall of the construction bin, and the man entering pipeline communicates with the manhole and fixedly connected with the construction bin in a sealed mode. The invention further discloses a dam face underwater repairing method using the device. According to the method, before construction, water in the construction bin is pumped out, adsorption of the construction bin on a dam face is achieved through the pressure difference between the interior and the exterior of the construction bin and a water stop device, a waterless construction environment is formed in the construction bin, and a construction environment equivalent to land surface dry land construction is provided.
本发明公开了一种坝面水下修复装置，包括施工仓及进人管道，施工仓为一面开口的空心柱体；其开口端朝向水平方向，其开口端的环形端面上由内至外依次设有主止水带及辅助止水带，辅助止水带的外边缘超出施工仓开口端的端面外边缘；其侧壁分别开有抽水孔及进人孔，进人管道与进人孔连通并与施工仓密封固接。本发明还公开了一种一种利用上述装置的坝面水下修复方法。本发明在施工前将施工仓内水抽空，利用施工仓内外压差和止水装置，实现施工仓在坝面上的吸附，施工仓内形成无水的施工环境，提供等同于陆面干地施工的施工环境。
