Lining trolley used for construction of main tunnel and emergency avoidance zone and its construction method

Abstract

The invention provides a lining trolley for construction of a main cave and an emergency vehicle avoidance strip. The lining trolley comprises a trolley body which comprises a main cave construction trolley body and emergency vehicle avoidance strip construction accessories. The main cave construction trolley body comprises a portal part and the like. The portal part comprises a portal truss, a bracket and the like. The portal truss comprises a portal cross beam and an adjustment oil cylinder assembly. The portal cross beam comprises two relatively movably arranged portal cross beam sections. The adjustment oil cylinder assembly comprises an oil cylinder and a telescopic oil cylinder extension which are arranged in series. The bracket comprises two detachably connected bracket cross beam sections. The emergency vehicle avoidance strip construction accessories comprise a top widening mold, a bracket cross beam extension and an auxiliary connecting piece. Through application of the lining trolley, demands of main cave section construction and emergency vehicle avoidance strip construction are simultaneously met, the assembly process of the lining trolley is simplified, the cost is reduced, and construction efficiency is improved. The invention further discloses a construction method of the lining trolley, the practicality is high, and working efficiency is high.

Description

technical field [0001] The invention relates to the technical field of lining trolley construction, in particular to a lining trolley used for constructing a main tunnel and an emergency avoidance belt and a construction method thereof. Background technique [0002] The emergency parking zone refers to the temporary parking zone used for temporary vehicle failure or emergency parking for other reasons on expressways and first-class highways. [0003] All existing road tunnels are equipped with emergency avoidance belts for temporary parking. In the prior art, separate lining is used for the construction of the main tunnel and the emergency avoidance zone, the details are as follows: [0004] The first method: firstly line the section of the main tunnel completely, and then use the small formwork to line the emergency avoidance zone. This method has low safety factor, complex process, low efficiency, poor molding quality and high labor cost when lining emergency avoidance s...

AI Technical Summary

Problems solved by technology

This method has low safety factor, complicated process, low efficiency, poor molding quality and high labor cost when lining emergency avoidance belts.

[0005] The second method: use the second lining trolley for lining construction, specifically: (1) Renovate the construction on the basis of the original main cave trolley. This method needs to transform the trolley many times during the construction process, and the reconstruction time is long. The parts need to be changed many times, and the labor cost is high; (2) An emergency vehicle avoidance belt trolley is manufactured separately to carry out the separate construction of the emergency vehicle avoidance belt, such as the application number 201210010568.2, and the patent name is "a retractable emergency belt The invention patent and application number of "tunnel lining trolley for traffic avoidance belt" is 201110225624.X, and the patent name is "a lining method for emergency avoidance zone of tunnel and tunnel lining trolley". This method requires an additional One emergency avoidance belt trolley increases the equipment investment cost, and the trolley needs to be disassembled and assembled multiple times when lining multiple emergency avoidance belts, which takes a long time and high labor costs
