An automatic control method for tunnel lining construction

Abstract

Disclosed is an automation control method for tunnel lining construction. A control system integrates all information collecting and control procedures of a traveling mechanism, a hydraulic system, aconcrete distribution device, a vibrating device, a temperature sensor, a flowmeter, a video monitor and a pressure sensor, is equipped with a GPRS wireless data transmission module, and can collect and upload information in the casting process of a tunnel lining to a project department monitoring room. The distribution device can be connected with a plurality of distribution pipes in series, thetemperature sensor is used for detecting the concrete casting temperature, and the flowmeter is used for collecting the concrete casting quantity and implementing automatic control over casting. The video monitor monitors real-time work picture information, and collects and transmits the real-time work picture information to the project department monitoring room. The vibrating device achieves vibrating automatic control operation for concrete. The pressure sensor detects and collects pressures of all points in the concrete casting process and displays the casted height of the concrete. The control system conducts concentration analysis on data collected in the casting process of the tunnel lining, gives out a control instruction, and uploads the detected data to the project department monitoring room.

Description

technical field [0001] The invention belongs to the technical field of tunnel lining construction, in particular to an automatic control method for tunnel lining construction. Background technique [0002] The lining is the main structure of the tunnel that bears the ground pressure and prevents the surrounding rock from deforming and collapsing. Its construction quality directly affects the construction and operation safety of the tunnel. The lining trolley is the mechanical equipment used in the tunnel lining construction process. The outer curved surface of the lining trolley is a curved formwork, which forms a closed space with the initial support wall of the tunnel and fills it with concrete. After the concrete is solidified, the curved formwork is removed, and the tunnel lining can be poured. [0003] Due to the closed nature of the lining construction, the data such as the amount of concrete poured, the temperature of the concrete entering the mold and the concrete p...

AI Technical Summary

Problems solved by technology

[0003] Due to the closed nature of the lining construction, the data such as the amount of concrete poured, the temperature of the concrete entering the mold and the concrete pressure cannot be accurately calculated during the lining pouring process. Few problems will eventually affect the quality of lining construction

[0004] The existing lining trolley automation control level is low, the concrete distribution and vibrating devices require a lot of manual labor, and the construction efficiency is low, which makes it difficult to guarantee the quality of the lining construction, and cannot solve the above problems

[0005] Combining the lining trolley and the vibrating device and adding various detection equipment with specific functions to realize the automatic control method of tunnel lining construction has not yet been reported.
