Tunnel secondary lining automatic constant temperature maintenance simple bench

Abstract

The invention relates to a large range, concretely to a tunnel secondary lining automatic constant temperature maintenance simple bench. The simple bench includes a box. Rolling wheels are fixedly mounted on the four corners of the lower side of the box. A groove is arranged in the left end of the box. A water outlet pipe is arranged on the lower end of the groove. A solenoid valve is arranged onthe left end of the water outlet pipe. A water level measuring pipe is arranged on the upper side of the water outlet pipe. A water pumping pipe is arranged on the right side of the water level measuring pipe on the upper side of the box. A water pump is mounted on the water pumping pipe. Fixed parts are mounted on the water pumping pipe on the left and right sides of the water pump. The upper side of the water pumping pipe is connected to a water spray pipe through a connection flange. The inner side of the lower end of the water spray pipe is connected to the box through fixing rods. Nozzlesare arranged on the outer side of the water spray pipe. A water storage cavity is arranged on the right side of the box. A vent is arranged in the right end of the top of the water storage cavity. Arotary aeration device is arranged on the upper side of the box. The tunnel secondary lining automatic constant temperature maintenance simple bench can facilitate heating treatment of equipment, canensure the automatic constant temperature maintenance of a tunnel secondary lining and facilitates the use of people.

Description

technical field [0001] The invention relates to a relatively large range, in particular to a simple platform for automatic constant temperature maintenance of the second lining of a tunnel. 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. The auxiliary equipment includes car avoidance tunnels, fire protection facilities, emergency communication and waterproof and drainage facilities. The long tunnel also has special ventilation and lighting equipment. [0003] The second lining is a term in tunnel construction. When the tunnel is excavated, it is driven forward along the face of the tunnel, and then the four sides of the tu...

Problems solved by technology

[0004] The currently published Chinese patent authorization announcement number is CN109681241A, a simple platform for automatic constant temperature maintenance of the second lining of the tunnel. Although the tunnel can be insulated, the equipment needs to be manually pushed, and the equipment needs to be connected to the water pipes used for tunnel construction. In this way, the temperature of the water sprayed on the tunnel wall cannot be guaranteed through the setting of an instant thermostat, and in the process of moving the equipment, the water pipe will also be dragged on the ground, which is not only labor-intensive, but also causes wear and tear on the water pipe. very inconvenient
