Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof sheet laying device for a tunnel. More specifically, it is intended to convert the installation of a waterproof sheet in tunnel construction from a conventional manpower to a mechanized construction.

[0002]

2. Description of the Related Art Conventionally, a waterproof sheet for a tunnel is laid.
Mainly, a waterproof sheet is mainly applied to the primary lining surface of the tunnel by means of human power, such as by using nails or fasteners. For example, in Japanese Patent Application Laid-Open No. 6-229198, when a sheet in which a waterproof sheet and a buffer cloth having water permeability are superimposed is laid on the primary lining surface of the tunnel, one press roller for expanding the sheet and a buffer cloth are provided. To peel off the waterproof sheet, turn both ends of the waterproof sheet with guide claws attached to both ends of the holding roller to expose both ends of the cushioning cloth, and then use a sheet for the worker on the work table to fix with nails. A mobile device is described. This is an apparatus for removing the waterproof sheet and cushioning cloth at both ends to reduce an operator's work of flipping the waterproof sheet at the time of nail driving or the like for fixing the waterproof sheet.

[0003]

The above-mentioned prior art has the following problems. 1. When laying a waterproofing sheet for tunnels, work is carried out using a work stand, etc., but work is performed manually, but it is often done at high places, and it also involves going up and down on the work stand, and furthermore, the waterproof sheet itself There is a problem in the workability and the like due to the weight, size, etc. 2. At present, the width of the waterproof sheet is about 2 to 3 m, but there are many joints of the waterproof sheet, and there is a problem in waterproof performance.

[0004] The present invention has been made in view of such problems of the prior art, and has as its object to provide the following. Change from conventional manual construction to construction using a mechanized system, and improve the waterproof performance, workability, economy, etc.

[0005]

Means for Solving the Problems In order to achieve the above object, the present invention is as follows. That is,
According to the present invention, a traveling rail portion 3 composed of a pair of guide traveling rails having the same size as the tunnel section is used.
And a drive unit 4 configured to travel from one end of the travel rail unit 3 to the other end, and another end of the travel rail unit 3 while being pulled by the drive unit 4 A sheet configured to run to the end and configured to rotatably support both ends of a roll-shaped waterproof sheet 7 configured to have a width corresponding to a distance between a pair of guide travel rails. The holder 5 and the waterproof sheet 7 drawn out from the sheet holder 5 are arbitrarily disposed with a locking device on the primary lining surface or on one surface of the waterproof sheet, and crimped to the primary lining surface of the waterproof sheet 7 from the center of the tunnel. This is a tunnel waterproof sheet laying device including a sheet pressing roller arm portion 6 configured to perform the above operation.

In this case, the following configuration can be adopted. The sheet holding roller arm section 6 is composed of a plurality of pressing roller arm units 6A, and the primary lining surface is rich in undulations, so that a plurality of pressing roller arm units 6A are provided separately so that the waterproof sheet 7 is provided. More secure to the primary lining surface. Holding roller arm unit 6A
Is the press roller arm 6A1 and press roller cylinder 6
A2.

The process of laying the waterproof sheet is as follows. 1. The sheet laying device has a structure in which guide traveling rails (H steel or the like) having the same size as the tunnel cross section are installed on the left and right sides, and a chain is attached to the primary lining surface side flange surface of the rail. The sheet laying device itself travels from the end of the guide traveling rail to the other end by two left and right drive motors. 2. First, the waterproof sheet has a nonwoven fabric or a number of protrusions as a water-absorbing material on the primary lining surface of the tunnel, and a fastening device having an infinite number of projections is fixed with a nail or an adhesive. There, the waterproof sheet for tunnel is pressed and fixed to the primary lining surface from the center side of the tunnel by the press roller arm unit 6A attached to the waterproof sheet laying device for tunnel. At this time, when the nonwoven fabric is fixed to the primary lining surface with a nail or the like, an arbitrary or linear engaging device is disposed on one surface of the waterproof sheet, and the engaging device is attached to the primary lining surface at any point. Alternatively, if the sheet is fixed in a linear manner, use a waterproof sheet as a water-blocking layer and a nonwoven fabric as a water-permeable cushioning material, and apply pressure from the surface of the waterproof sheet for the tunnel (center side of the tunnel). The structure is such that it can be fixed by sticking.
