A borehole-opening canal discharge device for a landslide dam in a water conservancy project.

Abstract

This invention discloses a drilling and channel-opening spillway device for a landslide dam in a water conservancy project. The device includes a housing and a drainage pipe. The drainage pipe is fixedly connected to the inside of the housing and is located at the center of the housing. A front rotating shaft fixing rod and a rear rotating shaft fixing rod are fixedly connected to both sides of the drainage pipe. A rotating shaft is movably connected between the front and rear rotating shaft fixing rods. A blade is fixedly connected to the water-in-the-water side of the rotating shaft, and a rotating shaft bevel gear is provided behind the blade. The rotating shaft bevel gear is fixedly connected to both sides of the rotating shaft. This invention utilizes the rising water level of the landslide dam to allow water to flow into the drainage pipe. While draining water, the blade inside the drainage pipe rotates, driving the rotation of the drill rod via an internal gear transmission shaft. The drill rod then slowly drills out of the housing through its own threaded structure and threaded hole, achieving the drilling purpose. Water is then injected into the dam through its outlet hole, causing a breach in the dam and preventing river blockage and downstream danger.

Description

Technical Field

[0001] The invention relates to the technical field of barrier lake treatment, and in particular to a barrier lake dam body drilling channel discharge device of a water conservancy project. Background Art

[0002] A barrier lake is a lake formed by the storage of water after a river valley or riverbed is blocked by a volcanic lava flow or a landslide caused by earthquake activity. A lake formed by a volcanic lava flow is also called a lava barrier lake. There are four processes in the formation of a barrier lake. The first is the original water system; the second is that the original water system is blocked by a blockage. The third is that after the river valley and riverbed are blocked, the water gathers and overflows to the surroundings. The fourth is that a barrier lake is formed when the water is stored to a certain extent. Once the barrier lake bursts, it will form a flood peak downstream. Improper handling will cause major disasters. Once a barrier lake is formed, there is a risk of bursting the dam downstream, and the river water in the upstream will rise, flooding fertile fields and residences, causing serious damage to people’s lives and property; so opening a channel to discharge water as soon as the river is blocked can minimize the harm.

If some of them have problems and cannot operate, it will not affect the operation of the structures in other boxes, and its purpose can be better achieved. BRIEF DESCRIPTION OF THE DRAWINGS
