Spraying system and construction method of a tunnel secondary lining spraying concrete maintenance system

Abstract

The invention discloses a spraying system and a construction method of a tunnel secondary lining spraying concrete maintenance system, including a machine case, the front side of the bottom of the inner cavity of the machine case is fixedly connected with a control host, and the tops of the left and right sides of the machine case are fixedly connected There is a rotating seat, and the inner part of the rotating seat is rotatably connected with a shaft tube, and the rotating seat communicates with the inner cavity of the shaft tube, and the two ends of the shaft tube are connected with a spray pipe assembly. The invention relates to the technical field of tunnel construction and maintenance equipment. The spraying system and its construction method of the spraying concrete maintenance system for the second lining of the tunnel, the electric push rod combined with the pulling frame and other structures can control the spray pipe components on both sides of the device and the strong light to swing up and down synchronously, thereby realizing automatic uniformity. The effect of spraying, and the strong light swings up and down while cooperating with the camera, which can provide the basis for subsequent functions such as concrete dryness identification and spacing identification. The structure is simple and easy to use, and automatic operation can be realized without manual control, reducing labor costs. .

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.
