Method for quickly anchoring caisson by rocket anchor to achieve plugging

A technology of rocket anchors and caissons, which is applied in the fields of caissons, buildings, and infrastructure engineering. It can solve the problems that caissons and dikes are prone to produce huge concentrated stress, be washed away by floods in a short time, and endanger the overall safety of the dam. Meet the effects of flood fighting and disaster relief, strong safety and reliability, and improved safety

Problems solved by technology

[0003] The existing caisson plugging technology has two fatal disadvantages. One is that the operation is too difficult. After the caisson is launched, it is very easy to be washed away by the torrent in a short time, and the effect of slowing down the plugging cannot be achieved. The second is that after the caisson is successfully plugged, Due to the huge impact force of the flood, the contact position between the caisson and the dike is prone to huge concentrated stress, which endangers the overall safety of the dam

Embodiment Construction

[0027] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] A method for quickly anchoring a caisson with a rocket anchor to plug a mouth described in a preferred embodiment of the present invention is realized according to the following steps:

[0029] Step 1, set single and double lug connecting members at the tail of the tugboat 10 and one side of the caisson 20, for the towing operation of the caisson 20, set the rocket anchor 30 and its launching device on the middle and upper part of the side plate of the caisson 20, and place one end of the rocket anchor 30 Connect the caisson 20 with an anchor chain. The length of the anchor chain needs to be calculated and determined in advance according to the depth and flow veloci...

Abstract

The invention relates to a method for quickly anchoring a caisson by a rocket anchor to achieve plugging. The problem that the caisson can not be fixed in the deceleration and decompression process is solved through the fact that the caisson is remotely controlled to explode and the rocket anchor provides anchoring force for the caisson, so that plugging is achieved quickly, precisely and safely.

Description

technical field [0001] The invention relates to a method for blocking mouths of rivers and lakes, in particular to a method for rapidly anchoring caissons with rocket anchors for blocking mouths. Background technique [0002] The caisson technology is an emergency technology similar to sunken ships to slow down the water potential at the entrance. There are a large number of box-type structures in our country, such as civil containers, pontoon equipment and boats of pontoon equipment. These box-type objects have good watertightness and regular appearance, and can float to the entrance after loading heavy objects on the water. After a certain position, implement blasting to sink the retaining dam body. Compared with sunken ships, the biggest advantage of caisson technology is that it realizes the integration of large retaining dams. The sinking of caissons is small in size and light in weight, and it has good controllability on the water, and it can be controlled to the desi...
