Efficient tunnel operation bridge equipment

Abstract

The invention discloses efficient tunnel operation bridge equipment. The efficient tunnel operation bridge equipment comprises a movable base and a bridge floor which is obliquely arranged, wherein a step ladder is arranged at the side edge of the bridge floor; or an escape way is arranged at the side edge of the bridge floor; or the step ladder is arranged at one side of the bridge floor and the escape way is arranged at the other opposite side of the bridge floor. The efficient tunnel operation bridge equipment has the advantages of simple structure, convenience for utilization, capability of easily improving the construction efficiency and safety and the like.

Description

technical field [0001] The invention relates to the technical field of underground engineering construction equipment, in particular to a high-efficiency tunnel operation bridge equipment. Background technique [0002] In the development of underground engineering construction, the new Austrian method in the mining method is a commonly used construction method in mountain tunnels. This method uses drilling and blasting as excavation methods, uses surrounding rock and structure as support design theory, and uses composite lining Structure, forming a process operation line based on drilling and blasting excavation, ballast loading and transportation, primary support, waterproof and drainage, secondary mold lining, auxiliary construction, etc. Among them, step excavation is the most widely used excavation method. It is not only suitable for II and III grade surrounding rocks with good geological conditions, but also suitable for IV and V grade surrounding rocks with poor geolog...

AI Technical Summary

Problems solved by technology

The current blasting and support construction uses more simple work platforms, manual handling, manual support, high labor intensity, long construction time, high safety risks, and construction quality and progress cannot be guaranteed.

[0003] In addition, mechanical equipment is also widely used in tunnel construction, such as rock drilling rigs, arch installation vehicles, wet spraying machines, etc. are used in drilling and blasting excavation, initial support processes, and further cooperate with excavators and loaders However, the anti-overturning of mechanical equipment and the rapid escape of operators have always been a difficult problem

A variety of equipment is relatively easy to deploy and lay out in full-face excavation construction, but in step excavation, the equipment needs to go up and down steps, and there are many equipment interferences within the safe step distance, which poses a greater risk of construction safety. The functions of construction equipment are relatively single, and there is no One device can integrate multiple functions and be used in the tunnel face excavation and support process, and multiple devices with single functions increase the construction cost
