Air shield dam construction method

Abstract

The invention discloses an air shield dam construction method. The air shield dam construction method comprises the following steps that 1, a dam bed is cleaned; 2, an inflation and exhaust pipeline is installed; 3, air inflating and pressure testing are carried out; 4, lofting is carried out on an air bag and a shield plate; 5, the air bag is adjusted in place and punched; 6, the shield plate is adjusted in place; 7, foundation flexible connection punching in place is carried out; 8, the shield plate is installed; 9, a side wall water stop belt is installed; 10, inflating and dam testing are carried out; 11, a limiting belt is installed; and 12, the dam height is debugged; In the first step, all stacked materials and sundries on the dam face are cleaned away, the surface of an air bag collapse section needs to be flat and smooth, and concrete attached to threads of embedded bolts is cleaned away by using a steel brush. According to the air shield dam construction method, an air shield dam structure is easy to install, low in manufacturing cost, few in maintenance and convenient to use, has the functions of safety, environmental protection, energy conservation and the like, and has a good landscape effect in landscape.

Description

technical field [0001] The invention relates to the technical field of river dams, in particular to a construction method of a gas shield dam. Background technique [0002] River dam, also known as "barrage dam"; artificially built water-retaining structures across the river; lower dams are also called weirs; during wartime, blowing up the dam causes the downstream river to flood, which can block the enemy in the pan-area However, the existing river dam structure is complicated to install, expensive to build, high to maintain, and not convenient to use, and the functions of safety, environmental protection, and energy saving are not high, and in terms of scenery, the landscape effect is not high. Contents of the invention [0003] The object of the present invention is to provide a gas shield dam construction method to solve the problems raised in the above-mentioned background technology. [0004] In order to solve the above technical problems, the present invention prov...
