device for sealing dam breaches

Abstract

A device for blocking a dike breach is used for rapidly piling and blocking the dike breach, and consists of a movable platform, a combined steel pipe pile, a support used for clamping the combined steel pipe pile, a fast-draining type piston impact pile driver, a fast-draining type heavy hammer impact pile driver, a power device and the like. According to the device, the dike breach can be blocked conveniently, about 90% of water can be blocked after the piling is finished, and is construction is rapid and convenient.

Description

[0001] This application is a divisional application, the filing date of the original application: 2011.03.20, the application number: 201110078093.6, and the title of the invention: a device for blocking the breach of a dam. technical field [0002] The invention relates to a blocking device, in particular to a device for blocking a dam breach. Background technique [0003] In the application document that the application number 201010184689.X proposed by me discloses the device for driving piles at the breach of the embankment, after the implementation of the scheme, it is indeed possible to drive piles at the breach of the embankment, but it is found that the following problems still exist in use: ①. After the steel pipe pile enters the water, due to the strong current, the pile and the inner wall of the bracket are pressed very tightly, and it is very useless to extend the pile into the bottom of the dam in the torrent. ②. Because the piles are driven in the torrent, it i...

Problems solved by technology

[0003] In the application document that the application number 201010184689.X proposed by me discloses the device for driving piles at the breach of the embankment, after the implementation of the scheme, it is indeed possible to drive piles at the breach of the embankment, but it is found that the following problems still exist in use: ①. After the steel pipe pile enters the water, due to the strong current, the pile and the inner wall of the bracket are pressed tightly, and it is useless to extend the pile into the bottom of the dam in the torrent.

When the inclination of the pile is large, it is difficult to ensure the verticality of the mobile platform because there is no leveling device on the bracket

③. Since there is no dedicated connector, the speed of forming a pile network from individual piles is slow and the operation is more complicated

④. The exhaust of the cylinder lower cavity of the piston impact cylinder and the hammer impact cylinder is not smooth, so that the impact force output by the impact cylinder cannot be fully exerted

However, if the section of the exhaust pipe is increased, the bending radius of the exhaust pipe must be increased, and the gas distribution section of the gas distribution valve must also be increased, which will increase the volume and weight of the pile driver.

⑤. The push rod of the hammer impact cylinder is composed of a solid push rod and a hollow push rod. The manufacturing process is complicated, and the work reliability is poor and easy to damage

If the rescue equipment cannot be deployed due to the harsh environment and there are fewer rescuers, then even if the piles have been laid, the breach cannot be quickly sealed.
