Breach cut-off device and cut-off method

Abstract

The present invention relates to a breach cut-off device. One or a plurality of water-absorption leakage-blocking bags which are connected in parallel with a rope are filled with high-water-absorptionresin. The two ends of the leakage-blocking bag connection rope are connected with a hollow steel pile fixed on the dam. The cut-off method comprises the following steps: A. respectively fixing fourhollow steel piles on two ends of the breach, and fixing two hollow steel piles on each end; B. mounting the breach leakage-blocking bags which are connected in parallel above the water surface of thebreach, and suspending on the links of four hollow steel piles at both ends, straining and hitting the breach leakage-blocking bags into the water with the steel bars; and C. placing the next group of breach leakage-blocking bags into the water with a same method until the last group of breach leakage-blocking bags exceeds the water surface for blocking the breach through the water-absorption expansion of the breach cut-off device. The leakage-blocking bag designed by the invention has better streamline property, bears less impact force of the breach current in entering the water, has more regular shape after water-absorption expansion and facilitates the compact arrangement between the bags. The transportation and field installation is convenient and quick. The breach cut-off device andthe cut-off method according to the invention have more practical value in flood emergency fighting.

Description

technical field [0001] The invention relates to a breach interception device and an interception method, and belongs to the technical field of leak plugging and interception materials and equipment. Background technique [0002] In flood fighting and emergency rescue, the breach of river levee is the main danger. Because once the embankment breaks, the flood will be uncontrollable and will cause huge damage and loss. At present, the commonly used plugging methods for breaches can basically be divided into three types: flat plugging, vertical plugging, and mixed plugging. Vertical blocking is to feed materials from both ends of the breach gradually to the middle to narrow the breach. When the dragon gate is formed, on the basis of sufficient material preparation and careful planning, rush to close the dragon and seal the air; flat blocking is to drive piles on the selected blocking line. Bridge, and laying rails on the bridge to transport stones or willow stone pillows, lay...

Problems solved by technology

The above three plugging methods all need to transport a large amount of materials in a relatively short period of time, and use large-scale mechanical equipment. If it catches up with continuous rainy weather, it will increase the difficulty of using large-scale mechanical equipment. If sandbags are carried manually, it will be very difficult for large breaches. Difficult to achieve
