Description

Chiseling device for repairing operated tunnel diseases

Technical Field

The utility model relates to a tunnel repair technical field, more specifically say, relate to an operation tunnel disease is restoreed with chisel hair device.

Background

With the continuous increase of the total mileage of railway tunnels in China, the defects of the operated railway tunnels are increasingly frequent, and the defects of cracking, chipping, net cracking, water leakage, frost heaving and the like of tunnel lining structures seriously threaten the running safety of trains.

Aiming at the problem of tunnel structure diseases, the engineering department usually adopts simple scaffolds and machines for maintenance, wherein the chiseling operation is one of the procedures with worse operation conditions. The existing tunnel defect treatment construction roughening method generally comprises the following steps:

manual scabbling: the air pick or the handheld pneumatic bush hammer is adopted for manual bush hammer, the quality of manual bush hammer is determined by the technology and experience of workers, incomplete and uneven bush hammer roughening is easily caused, and finally quality problems such as joint surface cracking and falling are caused. And dust cannot be effectively collected. The influence is easily caused to railway contact networks and optical cable conduits.

Hand-propelled or machine-mounted chiseling machine: through the design of handcart or machine-mounted formula, integrated a plurality of chisel hair heads, promote chisel hair efficiency. On one hand, however, the operation is carried out in a close distance manually, and only the side wall is roughened; on the other hand, the manual close-range operation also causes the workers to be still in the environment of straight-face scabbling pollutants, which causes harm to human bodies and can not effectively collect dust.

Mechanical roughening: the chiseling drill bit is arranged at the end of the mechanical arm of the small excavator, and workers chisel burrs in a cab through the control mechanical arm, so that the chiseling efficiency and the working environment are further improved. However, the method cannot avoid contact networks inside tunnels and optical cable wires on tunnel walls, cannot completely realize full-section mechanical construction, cannot well control the influence of dust caused by scabbling on the contact networks and the optical cable tubes, and still needs to improve the efficiency.

However, most of the existing tunnel arch installing equipment is designed aiming at the tunnel construction stage, and the actual working conditions in the operation tunnel defect repair are not considered. And the construction limitation is more in the operation tunnel defect repairing operation due to the operation property. Mainly comprises the following limitations:

1) The operation time is short, the operation can be carried out only in the operation skylight time (4-6 h) of the tunnel, the up-line and down-line time is deducted, the construction preparation time and the like, the actual operation time is less than 4 hours, in the current tunnel defect repair, an operation mode that manual work is mainly adopted and simple tools are auxiliary is adopted due to no proper machine tool, 7 skylight consuming time is needed for 12m sleeve bush scabbling installation, and the operation is carried out by more than 10 persons. Therefore, the higher requirements for the operation efficiency are put forward

2) The current building restriction in tunnel according to requirements such as national standard, planning and electrification, the contact net has generally been arranged at the tunnel top of having operated at present, and illumination line, private cable and public network cable have been arranged to the tunnel both sides, and because the atress requirement, the contact wire that the contact net hung arranges according to the zigzag, need avoid it during the construction, otherwise there are electric shock and destroy the circuit risk equipment device and personnel when the operation.

3) Transportation limitation, according to the requirements of the existing regulations and regulations, maintenance equipment and tools can only be conveyed by a railway locomotive meeting the requirements, and the maintenance equipment and tools carried in the running state of the locomotive need to meet the GB 146.1-2020 part 1 of the Standard gauge railway clearance: the rolling stock limits are not to be exceeded.

Therefore, under the above-mentioned limiting conditions, how to improve the arch center installation efficiency and quality when repairing the operating tunnel defect, reduce labor intensity, guarantee the safety of construction, and solve the problems of transportation, contact line avoidance and mechanical roughening are the problems to be solved urgently by those skilled in the art.
