Abstract

The invention relates to an underwater repair construction device for the upstream face of a dam, and belongs to the technical field of dam construction, the underwater repair construction device comprises a repair bin, the repair bin is attached to the upstream face of the dam, an operation opening is formed in the side wall, directly facing the upstream face of the dam, of the repair bin, and an opening and closing piece for opening and closing the operation opening is arranged on the repair bin; the face, deviating from the bottom of the dam, of the repairing bin is provided with an opening, a floating piece is arranged on the top face of the repairing bin, and the floating piece is used for enabling the opening communicating with the repairing bin to be located above the water storage face when the repairing bin dives; a first fixing piece is arranged on the repairing bin and located on the side wall where the operation opening is located, and the first fixing piece is used for fixing the repairing bin to the upstream face of the dam; the underwater repairing construction device for the upstream face of the dam further comprises a diving part, and the diving part is used for driving the repairing bin to dive to the position to be repaired. The method has the effect of shortening the construction period.

Description

technical field [0001] The present application relates to the technical field of dam construction, and in particular, to an underwater repair construction device for the upstream surface of a dam. Background technique [0002] A dam is a water retaining structure that intercepts the flow of a river channel to raise the water level or regulate the flow. It can form a reservoir, raise the water level, adjust the runoff, and concentrate the water head for flood control, water supply, irrigation, hydropower generation, and improved shipping. The river remediation buildings that adjust the river situation and protect the bank bed are also called dams, such as spur dams, dams and submerged dams. Dams can be divided into gravity dams, arch dams, buttress dams and prestressed dams according to their structure and stress characteristics. Now, gravity dams account for a large proportion of all types. [0003] A gravity dam is a dam that relies on its own weight to maintain stability...
