Dike breach closure device

Abstract

The invention provides a dike breach closure device. According to the dike breach closure device, water dike slopes on the two sides of a dike breach are protected by waterproof fabric so as to prevent the dike breach from enlarging again, the portions, on the two sides of the dike breach, of the dike surface are connected through four force cables, the force cables are divided into two sets in sequence, and four iron rails are placed in the dike breach along the corresponding force cables; and a proper point is set in each force cable set on the bank, iron columns are erected at the proper points, the top ends of the iron columns are connected through a circulating force cable, a water-retaining steel plate is vertically hoisted to the circulating force cable at the top end, two chains are fixedly placed at the top end of the water-retaining steel plate in advance in the mode that the cables are processed through skew intersection by using the length midpoints as the intersection points, the ends of the chains are connected with the top ends of hydraulic cylinders on transverse steel plates placed on the sets of iron rails respectively, the combination between the chains and the hydraulic cylinders are divided into two pairs in a skew mode, when one pair of hydraulic cylinders draws back, the water-retaining steel plate is pulled to move downwards, the other pair of hydraulic cylinders can stretch out at the same time, and therefore continuous stretching and drawing operation is conducted, the water-retaining steel plate can be vertically pressed to the underwater position with the mud depth of five meters along with the iron rails, the dike breach with the width of about 100 meters is covered block by block, and sealing of the dike breach and closure can be rapidly accomplished in about six hours.

Description

[0001] Technical field: [0002] The breach interception device of the present invention firstly limits the width of the breach, puts iron rods on both sides of the breach on both sides of the breach, wears iron rods every 5 meters, and rolls down the iron rod mounting wheels to protect them, and fixes them with piles , to prevent the mud on both sides of the breach from being washed away by the water, and collapse and expand. (As long as people hold this pass, no matter how fierce the flood is, the breach will be difficult to expand, and it will not cause much loss to the local people.) On the embankment, the The two sides of the breach are connected by 4 cables, and they are divided into two groups in sequence, and then the distance between the two cables in the group is determined according to the width of the embankment and the water depth. The distance between each group is finally Can be inserted into the water retaining steel plate shall prevail. And fix them respectivel...

Problems solved by technology

[0005] Since the beginning, there is no reliable scientific method to stop the breach of the levee in the world. It still depends on people to work hard, using materials, soil, stones and other primitive methods to block the breach, which takes a long time and consumes a lot of money, but has little effect , caused a huge threat to the lives of the people, and caused huge losses to the property of the country and the people. In order to solve all the above problems, a breach interception device was invented.
