Embodiment Construction

[0036] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0037] An inflatable equipment used for the installation of wide-width waterproof panels in tunnels, including inflatable bags, such as figure 1 As shown, the inflatable bag is composed of a horizontally arranged arched airbag 1 and a plurality of straight airbags 2, 22, 222. The straight airbags 2, 22, 222 are arranged longitudinally, and the straight airbags 2, 22, 222 are laid on the arched airbag 1, and the arched airbags 1 can be composed of multiple airbags, and the airbags are combined by connecting pieces 5. The two ends of the arched airbag 1 are provided with mounting bases 4, and the mounting bases 4 can adjust the position difference, and the position difference refers to the height. By adjusting the height of the mounting base 4, the arched airbag 1 can be raised. The above horizontal and vertical refer to the horizontal and vertical of th...

Abstract

The invention discloses an inflating device for mounting a tunnel wide-width waterproof board and a construction method and a mounting method. The inflating device comprises an inflating sac composed of an arched sac and a straight sac, the straight sac is erected on the arched sac, mounting bases are arranged at two ends of the arched sac, and both the arched sac and the straight sac are provided with inflating valves. The construction method of the inflating device includes steps of (1) unfolding the waterproof board to fix on the inflating sac of the inflating device; (2) inflating the inflating device to lift the waterproof board to an appointed position; (3) connecting the lifted waterproof board on an outline surface of a tunnel; (4) discharging and unloading the inflating device. Adjustment of mounting reserved sag of the waterproof board can be realized by inflating and deflating the straight sac in the process of mounting. The construction method and the mounting method of the waterproof board have the advantages of high construction efficiency, simplicity in operation, quickness, convenience, material conservation, high construction quality, safety, reliability and the like, and are applicable to on-site mounting and construction of the tunnel wide-width waterproof board and geotechnical cloth.

Description

Technical field [0001] The invention relates to an inflatable equipment used for the installation of a wide-width waterproof board in a tunnel. The invention also relates to a construction method for installing the wide-width waterproof board in a tunnel by using the above-mentioned inflatable equipment. Background technique [0002] At present, the tunnel waterproof board generally uses 1-1.5 mm thick polyethylene waterproof board, which has a width of 3-7 meters and a weight of 1.5 kg per square meter; a double-lane tunnel with a width of 3 meters has a single width of 150 kg; 3 A single-track tunnel with a width of meters can weigh up to 100 kilograms; a double-track tunnel with a width of 7 meters can weigh up to 330 kilograms; and a single-track tunnel with a width of 7 meters can weigh up to 220 kilograms. [0003] At present, the installation method of waterproof board is mostly by using (simple trolley) bracket method and manual installation method. The entrusted weight li...
