Tunnel secondary lining construction process monitoring system

Abstract

The invention discloses a tunnel secondary lining construction process monitoring system. The tunnel secondary lining construction process monitoring system comprises a sensor A, a sensor B, a sensorC, a display terminal and an adhering type vibrator. The sensor A is arranged on a secondary lining trolley and used for monitoring a concrete flowing route. The sensor B is used for monitoring preset-elevation pouring. The sensor C is used for monitoring the position of concrete in a bin. The display terminal is connected with the sensor A, the sensor B and the sensor C and used for achieving data acquisition and monitoring. The adhering type vibrator is connected with the display terminal and can be driven by the display terminal. According to the tunnel secondary lining construction processmonitoring system, a plurality of sensors with different functions are arranged, so that monitoring can be carried out in a tunnel secondary lining construction process in terms of whether concrete flows through a certain specific portion or not, the vibration starting and stopping time and vibration time control of the vibrator, whether concrete is poured in place or not and the like, corresponding executing equipment can be controlled according to monitoring results, and the concrete pouring quality is improved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a monitoring system for the construction process of secondary lining of tunnels. Background technique [0002] At present, the quality control of tunnel secondary lining construction mainly adopts the techniques of concrete layering and binning, timely vibration and maintenance to ensure the quality of concrete pouring. At present, the solution adopted by the tunnel to ensure the quality of concrete pouring is that the construction personnel supervise and urge the operators to complete the secondary lining construction on the site. Defects such as pockmarked surface, insufficient strength, and empty vault. [0003] In the construction process, the concrete is directly pumped into the tunnel through the vault hole. Because the vertical drop height and horizontal movement distance of the concrete exceed the specification requirements, the concrete segregates. In additi...

Problems solved by technology

At present, the solution adopted by the tunnel to ensure the quality of concrete pouring is that the construction personnel supervise and urge the operators to complete the secondary lining construction on the site. Defects such as pockmarked surface, insufficient strength, void of vault, etc.

[0003] In the construction process, the concrete is directly pumped into the tunnel through the vault hole. Because the vertical drop height and horizontal movement distance of the concrete exceed the specification requirements, the concrete segregates. In addition, due to irregular vibration, even vibration leakage is common. In addition, the maintenance work in the later period is not in place, resulting in quality problems
