Spraying system of tunnel secondary lining spraying concrete curing system and construction method of spraying system

Abstract

The invention discloses a spraying system of a tunnel secondary lining spraying concrete curing system and a construction method of the spraying system. The spraying system comprises a machine box, wherein a control host is fixedly connected to the front side of the bottom of an inner cavity of the machine box, rotating bases are fixedly connected to the tops of the left side and the right side ofthe machine box, shaft pipes are rotatably connected into the rotating bases, the rotating bases communicate with inner cavities of the shaft pipes, and a spraying pipe assembly communicates betweenthe two ends of each shaft pipe. The invention discloses a spraying system of a tunnel secondary lining spraying concrete curing system and a construction method of the spraying system. The electric push rod is matched with the pulling frame; the spraying pipe assemblies on the two sides of the device and the accent light can be controlled to swing up and down synchronously; and the accent light is matched with the camera while swinging up and down, so that a basis can be provided for subsequent functions such as concrete dryness identification and spacing identification, the structure is simple, the use is convenient, automatic operation can be realized, manual control is not needed, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of tunnel construction and maintenance equipment, in particular to a spray system and a construction method of a tunnel secondary lining spray concrete maintenance system. Background technique [0002] A tunnel is an engineering building buried in the ground, and it is a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, and mine tunnels. The structure of the tunnel includes two parts, the main building and the auxiliary equipment. The main building is composed of the tunnel body and the tunnel door, and the auxiliary equipment includes car avoidance tunnels, fire-fighting facilities, emergency communication and waterproof and drainage facilities, and the long tunnel also has special ventilation and lighting equipment. [0003] After the construction of the concrete wall in the tunnel, affected by the temperature and humidity, it needs...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a spraying system and its construction method of the second lining spraying concrete maintenance system of the tunnel, which solves the problem of manual propulsion or direct use of water pipes for spraying, which is relatively troublesome and requires a large amount of spraying. It is not easy to control, and at the same time, manual operation is laborious. However, when using some automatic sprinkler devices, when moving in the tunnel, even if the control is to walk in a straight line, the device will be offset due to the influence of ground unevenness and gravel, which will affect both.
