Problems solved by technology

Compared with the previous patent application, this patented technology has the outstanding advantage of saving a large amount of fillers, but it still has the following disadvantages: 1. Because the rapid water flow exerts a huge pressure on the formed "screen", it is necessary to use metal mesh One or several rows of piles can be supported on the downstream (downstream) side; 2. It is very difficult to cover rubber leather or plastic leather on the metal mesh due to the rush of water flow, and it is difficult to correct once the deviation is laid

Embodiment Construction

[0017] see figure 1 Beam 1 is made of Ф250 mm steel pipe; vertical pole 2 is made of Ф60 mm steel pipe, and the upper end ring is bent with Ф20 mm round steel, and its inner hole is Ф260 mm.

[0018] see figure 2 , the water bag 3 is made of artificial leather or canvas. The mouth of the bag is provided with a flange-like rigid support ring 4, and the ring surface is provided with a small hole 5 convenient for threading and tying; the top of the bottom of the water bag 3 is provided with an air hole 6, and the bag is provided with a floating ball 7, which floats on the On the water 8 in the water bag, the diameter of the float 7 is slightly greater than the diameter of the air hole 6.

[0019] see image 3 , when the crevasse is narrow, a steel pipe can be used as the crossbeam 1, put on the vertical rod 2 (the number can be calculated according to the width of the crevasse and the diameter of the rigid support ring 4), and the cross arm is placed on the embankment 9 on bo...

Abstract

The present invention relates to water engineering facilities for control and utilization of river, seacoast, etc. and is especially one flood fighting burst cutting off setting. The flood fighting burst cutting off setting includes one cross beam to be set over the burst, one row of uprights hung on the cross beam to be inserted obliquely and upstreamly into silt in the water bottom, and water bags tied to the uprights with air hole in the up side and float balls of diameter greater than the air hole inside the bag.

Description

Technical field: [0001] The invention relates to engineering related to the control and utilization of streams, river courses, coasts or other sea areas, in particular to an intercepting device for river or reservoir dam breaches (breaks). Background technique: [0002] The most important method of resisting floods and obstructing flow is still to utilize manpower at present, gather materials on the spot, pile up in the current with the fiber (cloth) bag that fills sandy soil. This method is simple and easy, and the response speed is fast, but the on-site implementation is dangerous and the interception efficiency is low. In order to resist this serious natural disaster, people have developed various blocking and intercepting devices. On November 30, 2002, the State Intellectual Property Office disclosed a patent application for a "blocking device" (publication number: 1380468A). The "burst blocker" is composed of supports, nets and pull ropes. It is shaped like an umbrella...
