Device for blocking dike breach

Abstract

The invention discloses a device for blocking a dike breach. The device comprises combined steel pipe piles C, movable platforms B, a piling machine, upstream connecting rods E, downstream connecting rods F and horizontal tie rods D, wherein the movable platforms B are arranged on the combined steel pipe piles C through brackets G, the upstream connecting rods E are connected with the upper parts of the combined steel pipe piles C at the upstream of a pile net in a longitudinal direction, the downstream connecting rods F are connected with the upper parts of the combined steel pipe piles C at the downstream of the pile net in the longitudinal direction, and the horizontal tie rods D are connected with the upper parts of the combined steel pipe piles C at the upstream and the downstream of the pile net in a horizontal direction. According to the device disclosed by the invention, the dike breach is quickly and conveniently blocked, the standardization and the modularization of rescue work are realized, the rescue work is more convenient and quicker, the labor intensity is reduced, and the loss caused by flood disaster is reduced to the maximum.

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...

[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.
