Construction method capable of intelligently monitoring and alarming concrete compactness of tunnel lining in real time

Abstract

The invention belongs to the technical field of building engineering construction and discloses a construction method capable of intelligently monitoring and alarming concrete compactness of a tunnellining in real time. The construction method capable of intelligently monitoring and alarming the concrete compactness of the tunnel lining in real time comprises the steps of checking and recheckingthe section of the lining; measuring and checking a clearance of a tunnel primary support section, treating a clearance-intrusion part, and re-measuring on the clearance of the tunnel primary supportsection; using a backhoe excavator to clear the bottom and treating a base surface; carrying out waterproof and drainage construction treatment on a tunnel and mounting a made micro driver; carrying out inverted arch and inverted arch filling construction; carrying out tunnel second lining concrete pouring; when the pouring process approaches a vault, switching on a monitoring sensor circuit; whenthe compactness of the concrete reaches requirements, switching on a circuit system, enabling an audible and visual alarm to give an arm, and showing that the pouring of the section reaches the requirements; and when the requirements are not met, using a die grouting process to perform filling in time. According to the construction method capable of intelligently monitoring and alarming the concrete compactness of the tunnel lining in real time, the vault concrete pouring quality is monitored in real time, and the vault concrete pouring compactness is enhanced; and the secondary lining construction quality can be improved, and the secondary lining and primary support void can be prevented.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a construction method for real-time intelligent monitoring and alarming of the density of tunnel lining concrete. Background technique [0002] At present, the closest existing technology: tunnel engineering occupies a very large proportion in engineering construction in my country. Tunnel lining refers to a permanent support structure built with reinforced concrete and other materials along the periphery of the tunnel body in order to prevent the deformation or collapse of the surrounding rock. [0003] In the prior art, under the condition that the primary support of the tunnel has been carried out, the inner lining, ie, the secondary lining, is generally constructed of materials such as concrete to achieve the functions of reinforcement and support. At the same time, for tunnels constructed with the "New Austrian Method", the secondary lining acts...

AI Technical Summary

Problems solved by technology

[0005] To sum up, the problems existing in the existing technology are: the construction quality of the existing secondary lining is not good, and the phenomenon of voiding at the top is prone to occur, resulting in a decrease in the integrity of the concrete and poor local quality, and the cost of repair is increased
