Structure and connecting and construction method for buoyancy dam type emergency water retaining small dike

Abstract

The invention discloses a flexible emergency water retaining small dike capable of being quickly constructed by splicing combination. A dam body can autonomously lift and descend along with the rise and fall of a water level by means of own buoyancy. The basic structure of the emergency water retaining small dike comprises a water retaining dam body, basic dam cloth, an anchor pile, anchor lines, a dam body buoyancy body, a wave resistant ridge, a basic water stop and air closed curtains. The flexible emergency water retaining small dike has the advantages of high integrity, simple and convenient construction, high construction speed, low labor intensity, good effect of retaining water and resisting waves, safety and stability in operation, low construction cost and the like.

Description

Technical field [0001] The invention relates to an emergency water-retaining sub-dyke designed by utilizing the structural principle of a buoyancy dam and a method for quickly connecting the structure thereof. Background technique [0002] In the invention patent (ZL02135426.X) entitled "fixed buoyancy dam, mobile buoyancy dam and its construction method" authorized on May 21, 2008, a kind of buoyancy that can rely on its own buoyancy and follow the water level is disclosed. A mobile flexible dam that fluctuates and rises autonomously—a mobile buoyancy dam. The dam can be quickly constructed by splicing and combining. Its basic structure is as follows: figure 1 Shown includes retaining dam body 17, foundation dam cloth 30, anchor pile 31, anchor rope 32 and 33 four parts. The dam body 17 of the dam is composed of many horizontally distributed buoyancy bodies 18 regularly arranged and fixed on the retaining dam cloth, the lower end is connected to the foundation dam cloth 30...

AI Technical Summary

Problems solved by technology

However, mobile buoyancy dams are insufficient in preventing wind and romantic overflow at the top of the dam.

[0010] 4. Since the top of the mobile buoyancy dam always floats on the water surface when it blocks water, it is prone to overflow under the action of wind and waves

[0011] 5. The unit cost of the mobile buoyancy dam with the existing design is relatively high

Because the buoyancy body of the dam body is made of high-density plastic as the shell, and the upper and lower ends of the dam body and the left and right ends are reinforced with steel plates to form the coupling head, which not only increases the average unit weight of the dam body, but also makes the unit cost of the dam body relatively low. high
