Description
Technical Field
The invention relates to the technical field of segment spraying, in particular to a tunnel segment spraying device.
Background
| Since the 21 st century, the underwater tunnel in China enters the rapid development stage, brilliant achievements are achieved, and a large amount of built and under-construction projects greatly promote the underwater shield tunnel in China and even in the world The progress of the technology. However, the shield tunnel concrete pipe is directly influenced by the surrounding complex environment, the concrete is neutralized, the chloride and sulfate in the saline soil are corroded, and the water flow is washed by And mechanical collision and other physical and chemical actions bring serious corrosion and damage to the concrete segments of the shield tunnel. For a long time, people mainly focus on improving the strength of concrete In the prior art, the corrosion prevention requirement of concrete is neglected, so that a part of shield tunnel concrete segments fail early due to material corrosion and even collapse accidents occur. |
| The existing anti-corrosion treatment for the pipe piece mainly comprises the following steps: and coating a silane impregnating material on the surface of the pipe piece. The primary method of field operation is simple can spray And air-curing, because the liquid silane product has low viscosity and is easy to volatilize, the effective components can be greatly lost when the liquid silane product is coated and air-cured, and the corrosion resistance of the concrete is reduced. |
Disclosure of Invention
The invention aims to provide a tunnel segment spraying device to solve the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme:
the utility model provides a tunnel segment spray set, includes liquid storage pot, air compressor, gas-liquid mixer, sprays component, controller and detection component, and wherein air compressor's output connects the air input end of liquid storage pot and gas-liquid mixer respectively, and the liquid storage pot passes through the transfer line to be connected with gas-liquid mixer liquid input end, and the output of gas-liquid mixer carries out the spraying through spraying the component to the section of jurisdiction, the spraying signal feedback that detects the component to the controller, the controller is according to spraying signal control gas-liquid mixer and spraying the component.
The detection component adopts a reflection type photoelectric sensor.
And a recovery tank is arranged at the bottom of the tunnel segment and used for recovering the liquid sprayed by the spraying component and conveying the liquid back to the liquid storage tank.
Compared with the prior art, the invention has the beneficial effects that: the spraying efficiency of the shield tunnel segment is greatly improved by spraying high-pressure vaporific coating on the spraying ring pipe to the surface of the shield tunnel segment, the construction is simple, convenient and quick, the spraying effect of the silane impregnating material is good, the efficiency is high, the protection effect is reliable and excellent, and the spraying device has good market promotion prospect.
