Description

Work platform for tunnel with work basket {Work Platform for Tunnel}

The present invention is mainly used for tunnel waterproofing work, and the outside relates to a worktable that can be used for various tunnel-related work, such as excavation and rehabilitation of tunnel construction, maintenance of the completed tunnel.

In general, the tunnel construction proceeds in the order of excavation, rehabilitation, and the rock surface formed by the excavation work such as blasting is covered with a shotcrete layer by the first rehabilitation work, after which the lining concrete layer is added to the shotcrete by additional drilling Covered. Prior to further drilling, waterproofing is to be carried out, which includes attaching the waterproof sheet to the shotcrete layer. The waterproof sheet is classified into a type in which a non-woven fabric is pre-attached as a protective sheet on the contact surface with the shotcrete layer and a type that does not. In the case of the latter waterproofing construction, the protective sheet is attached to the shotcrete layer, and then the waterproof sheet is attached to the protective sheet. The constructed waterproof sheet is interposed between the shotcrete layer and the lining concrete layer to prevent water from the rock surface from seeping into the lining concrete layer.

Such tunnel construction requires various tools such as a rock drill and a waterproof sheet construction roller, and requires a variety of tools and requires quite a lot of manpower. In addition, the aerial platform is one of the things that must be equipped, but the aerial platform must be raised and lowered by the operator from time to time, and the construction equipment, waterproof sheet, etc., which are relatively heavy, are placed on the aerial platform. Considering the need to fly, it was very difficult and dangerous. Therefore, in recent years, the necessity of mechanization for tunnel construction in order to reduce labor costs and improve workability has emerged, and development and research on this are urgently required. Of course, this is not an issue that is limited to the construction of silk tunnels, but also applies to the maintenance of completed tunnels (eg, replacement of lighting fixtures, tunnel cleaning, etc.).
