Abstract

The invention discloses a method for rapidly coping through type burst of a dam, which is characterized in that piping is often generated in a loose soil place of the dam when high-flow flood attacks, and the through type burst is generated along with the expansion of a transverse crack in the dam.

Description

Method for rapidly coping through type breach of dam

Technical Field

The invention discloses a method for rapidly coping with a through type breach of a dam, and relates to a solution for coping with an emergency through type breach of a river dam.

Background

When large-flow flood attacks, piping often occurs in loose soil places of the dam, and through type burst occurs along with expansion of transverse cracks in the dam. On the basis of the actual measurement record of the dangerous case, it is very necessary to summarize and analyze the processes and characteristics of the occurrence, development, emergency maintenance and the like of the penetrating breach of the dike.

Disclosure of Invention

The invention relates to a method for rapidly coping a through type breach of a dam, which forms a fast-assembly flood control wall constructed by vacuum adsorption connection structures by rapidly assembling flood control module devices, and the fast-assembly flood control wall is hoisted and thrown to a breach area by equipment to effectively block water flow and reduce the threat of flood disasters.

Drawings

Fig. 1 is a view of the steps of a solution, and fig. 2 is a cross-sectional view of a foundation device member-a ready-to-assemble flood protection module of a flood protection module wall.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, an embodiment of the present invention is shown in fig. 1, which is a detailed step of a method for rapidly coping with a through breach of a dam, including calculating a shape and a size of the breach, a water flow rate and an average flow rate (1) in a breach area, rapidly constructing a flood control module wall (2), and hoisting the flood control module wall to a breach area (3).

Fig. 2 is a cross-sectional view of a quick-assembly flood protection splicing module, which is a basic device member of a flood protection module wall, and includes a vacuum absorption connection groove (4), a vacuum suction pump (5), a double-flow suction water pump (6), a micro water flow monitoring device (7), a water inlet and outlet pipeline (8), an electromagnetic valve (9), a slidable connection rod (10), and the like.

Claims

1. A method for rapidly coping with a through-type breach of a dam is disclosed, wherein a figure 1 shows a coping solution scheme, and comprises the steps of calculating the shape and size of the breach, the water flow rate and the average flow (1) of a breach area, rapidly constructing a flood control module wall (2), hoisting the flood control module wall to a breach area (3) and the like; fig. 2 is a cross-sectional view of a foundation device member of the flood control module wall, namely a ready-to-assemble flood control splicing module, which comprises a vacuum adsorption connecting groove (4), a vacuum suction pump (5), a double-flow suction water pump (6), a micro water flow monitoring device (7), a water inlet and outlet pipeline (8), an electromagnetic valve (9), a slidable connecting rod (10) and the like; after the situation of bursting a mouthful appears running through, will organize the manpower immediately and carry out the analysis to the situation of bursting a mouthful to command hoist and mount machine to splice fast and inlay and build the flood control wall that uses ready-package flood control module as the base member, reorganize the flood control wall after the hoist and mount machine will accomplish again and put in to bursting a mouthful district.

2. The method for rapidly coping with the through type breach of a dam according to claim 1, wherein the ready-package flood protection splicing module is made of high-molecular wear-resistant and corrosion-resistant materials, can endure long-time water flow brewing and avoid the peeling effect of the original water flow, is 1x1x1m hexahedron structure, is internally provided with a micro motor-driven double-flow suction water pump (6) and a water inlet and discharge pipeline (8), and can perform moderate water absorption and flood discharge work while resisting the impact of flood peak.

3. The method for rapidly coping with the through type breach of dam according to claim 1, wherein the connection manner between the ready-package flood protection splicing modules is vacuum adsorption type connection, and during the assembly process (2), the assembly personnel needs to butt-joint and embed the vacuum adsorption connection grooves (4) on the flood protection module plate surface, and simultaneously use the vacuum suction pump (5) inside the module to suck the air between the connection areas of the two modules, so as to create the vacuum connection environment between the modules.

4. The method for rapidly coping with the through type breach of dam according to claim 1, wherein the double-flow water suction pump (6) installed inside the flood control module wall can absorb the external flood into the water storage space inside the module through the water inlet pipe, the gravity action of the whole flood control wall is increased by the self-water storage of the flood control module, after all the modules store water, the electromagnetic valve (9) inside the module opens the water drainage pipeline to slowly discharge the water downstream at an extremely low speed, and the maximum water depth value under the water level early warning line planning of the whole river is not exceeded.

5. The method as claimed in claim 1, wherein the step of the solution is started when the information of the river breach is received, and the step of the solution is started, and the installation of the flood protection module wall is started in response to the first time, and according to the shape and the location area of the breach, scientific researchers can plan a set of water treatment solution according to local conditions, so as to determine the number of the flood protection modules to be selected and the building shape of the flood protection modules, and the hoisting machine can fast install the flood protection module wall on the bank of the flood occurrence place, and the construction of 500 flood protection walls can be expected within 10 minutes.
