A kind of anti-scour equipment and application method of special pile net for embankment rapid plugging and emergency rescue

Abstract

The invention provides pile net anti-impact equipment special for dike rapid breach-closure rescue and a using method of the pile net anti-impact equipment. The pile net anti-impact equipment comprises anti-pull pile groups, an anti-impact net, guide ropes and auxiliary piles. The anti-pull pile groups comprise prefabricated steel piles, steel strands and steel strand connectors; one edge of the anti-impact net is connected with steel rings, and the opposite edge of the anti-impact net is connected with balancing weights; and the guide ropes comprise the fixed guide rope and the movable guiderope. During using, the multiple prefabricated steel piles are pressed into the positions, at the two ends of an entrance door, of a dike body to form the anti-pull pile groups; then the guide ropes are pulled to stretch across a breach, the movable guide rope pulls the anti-impact net to slide along the fixed guide rope to be expanded and fixed, and then the fixed guide rope and the anti-pull pile groups at the two ends of the entrance door are connected; and finally, the anti-impact net is laid at the bottom of the breach in a reverse flow mode. Impact force borne by the anti-impact net in the breach-closure process can be transmitted to the deep part of a dike foundation, thus the dike foundation-pile-net collaborative anti-impact effect is realized, large anti-impact force can be provided for attacking and occupying for breach closure, the breach-closure rescue efficiency can be improved significantly, and the pile net anti-impact equipment is suitable for rapid rescue of small andmedium-sized breaches.

Description

technical field [0001] The invention relates to the technical field of embankment emergency rescue, in particular to a pile net anti-scour equipment and an application method specially used for embankment quick plugging and emergency rescue. Background technique [0002] As an important part of the flood control and disaster reduction system, embankment engineering is an important safety barrier against floods. In recent years, the situation of flood control and flood fighting in my country has become more and more serious, and the frequency of dike dangers has increased unabated. Among them, the danger of breaches has the characteristics of a wide range of influence and serious consequences of loss of danger, which is extremely harmful to people's lives and property safety. [0003] Bursts have the characteristics of concentrated water head and fast flow, and most of them are thrown by manpower. The weight of thrown materials must be within the range that can be tolerated b...

Problems solved by technology

[0011] Aiming at the problem of insufficient anti-scourability of the scour-blocking structure of the existing plugging technology or time-consuming and labor-intensive anti-scour measures, the present invention provides a kind of pile net anti-scour equipment and application method specially used for rapid embankment plugging and emergency rescue. The piles are quickly inserted into the embankment foundation at both ends of the breach, and after being fixed through the guide wire and the anti-scour net, they are connected to the uplift piles at both ends of the breach, and the anti-scour net is laid on the bottom of the breach water flow, so as to intercept the throwing and filling materials and reduce the Churn rate
