Traffic-uninterrupted expressway tunnel pavement upheaval disease treatment method

Abstract

The invention belongs to the field of civil engineering, and particularly relates to a traffic-uninterrupted expressway tunnel pavement upheaval disease treatment method, which comprises the followingsteps of setting construction sequence lanes, setting temporary safety facilities and laying, detaching a cable trough on the side of the implementation lane, and arranging a foot locking steel pipeon the inner side of the original cable trough, excavating a road surface in a segmented groove jumping manner, arranging profile steel cross beams and channel steel longitudinal beams, casting a concrete bottom plate, a concrete leveling layer and a concrete pavement in place, and guiding and changing traffic lanes, and repeating. According to the method, a steel pipe pile and steel beam structure and concrete transverse support bottom plate combined reinforcing method is adopted, so that the upheaval disease of the pavement can be thoroughly treated under the condition that only one lane ofthe expressway is closed, and the tunnel structure and the operation safety are ensured.

Description

technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to a treatment method for road surface uplift in expressway tunnels without interrupting traffic. Background technique [0002] Since the beginning of the new century, the mileage of expressway tunnels in my country has increased rapidly. Due to the linear requirements, the tunnels often pass through expansive weak strata such as muddy and carbonaceous. The tunnel is an underground hidden project, the load and environment are complex and difficult to measure, coupled with reasons such as survey design and on-site construction not in place, it is very easy to have road surface uplift during the operation period, affecting the safety of tunnel operation. [0003] In view of the above-mentioned tunnel bottom structural diseases, invert restoration or inversion addition is often adopted for thorough treatment, but usually it is necessary to close the traffic and divert the t...

AI Technical Summary

Problems solved by technology

The tunnel is an underground concealed project, the load and environment are complex and difficult to measure, coupled with reasons such as survey design and on-site construction not in place, it is very easy to have road surface uplift during the operation period, which affects the safety of tunnel operation

[0003] In view of the above-mentioned tunnel bottom structural diseases, invert restoration or inversion addition is often adopted for thorough treatment, but usually it is necessary to close the traffic and divert the traffic of passing vehicles, which has a great impact on the traffic of the nearby road network, and the pressure from road users and management units is also high. It is getting bigger and bigger; tunnel bottom grouting reinforcement can close a lane for construction, but the treatment is not thorough, the disease may recur to a large extent, and there are certain hidden dangers in the safety of the tunnel structure
