Description

Technical Field

[0001] The utility model relates to the technical field of drain hole jacking pipes, in particular to a water outlet auxiliary device for a drain hole jacking pipe in a reservoir. Background Art

[0002] Reservoir drainholes are specialized structures designed to lower reservoir water levels and reduce storage capacity. Typically constructed within caverns, they primarily include drainholes and bottom drainholes. Their primary functions include flood discharge, diversion, water supply, and sediment removal. By creating a flow channel through openings on the reservoir bank or dam body, water is released from the reservoir into the downstream river. Pipe jacking is a non-excavation, advanced pipe laying technique. Its advantages include minimal or no impact on the surrounding environment, a small construction site, and low noise levels. Furthermore, it allows for deep underground construction, a feature unmatched by excavated pipe laying.

[0003] When the existing reservoir drain hole is used for pipe jacking construction, the pipes are in a clamped state, which causes water to seep into the pipes during underwater construction, affecting the normal construction of the pipes. In order to prevent this water seepage from affecting the normal construction of the pipes, we have designed a reservoir drain hole pipe jacking water outlet auxiliary device to prevent water seepage from occurring inside the pipes.
