Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a moving partition in a tunnel for partitioning a space in the tunnel for curing concrete cast on the wall surface of the tunnel.

[Prior art]

As a conventional partitioning tool for moving in a tunnel of this type, a steel frame member is attached along a wall surface in the tunnel cross-section, and a steel plate to be a partition wall is connected and fixed to the frame member. It is known that the space inside the tunnel is partitioned.

[0003]

[Problems to be solved by the device]

 However, in the conventional moving partition in a tunnel, it is necessary to assemble a steel frame material or plate material along the wall surface in the tunnel with a large-scale tool, which is troublesome to assemble and dismantle and is troublesome. The purpose of this is to prevent the pipes and the entrances and exits, etc. laid inside the tunnel from being cumbersome to handle, and to prevent a sudden temperature difference between the placed concrete and the outside air. There was a problem that it was not very suitable for

The present invention has been made in view of the above problems, and can be quickly and easily assembled in a tunnel to satisfactorily cure the concrete placed in the tunnel and easily removed. The purpose is to provide a moving partition in a tunnel that is convenient to carry around.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention is a moving partition in a tunnel that is attached in the direction of the tunnel cross section to partition the space in the tunnel, and expands by injecting a fluid such as air or water. An annular tube that is in close contact with a wall surface in the tunnel, and a sheet that is integrally provided on the annular tube and covers an inner circumferential side space surrounded by the annular tube are provided.

According to a second aspect of the present invention, the annular tube is housed in a bag-shaped annular housing portion formed on the outer periphery of the seat.

According to a third aspect of the present invention, the seat is provided with an opening / closing opening at a predetermined position.

[0008]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a moving partition in a tunnel according to the present embodiment, and reference numeral 1 is an annular tube. The annular tube 1 is inflated so as to be in close contact with the wall surface of the tunnel 2 along the cross-sectional direction of the concrete wall surface 3 (or the shield surface). And an injection port 4 for injecting a fluid such as air or water at a predetermined location. The fluid to be injected may be a fluid other than air or water.

The tube 1 is housed in a bag-shaped annular housing portion 6 formed on the outer peripheral edge of the seat 5. The seat 5 is a plastic curtain that covers the inner peripheral side space portion surrounded by the annular tube 1, and the outer peripheral annular storage portion 6 may be folded into a bag shape by folding back the outer peripheral portion of the seat 5. A body-made product may be attached to the outer periphery of the seat 5. The sheet 5 and the annular storage portion may be bonded by welding or sewing, or the tube 1 and the sheet 5 may be directly bonded. Further, the material of the sheet may be rubber or cloth other than plastic.

An opening / closing port 7 is provided at the center of the seat 5 or below the center. This access port 7 is used for workers to enter and leave the tunnel space separated by the seat 5, and a slit 8 (or a fastener) (or a slit 8) is formed in a part of the seat 5 to form a rectangular side. It can be opened and closed by installing a magic tape etc.

Next, with reference to FIGS. 2 and 3, a method of mounting the in-tunnel moving partition according to the present embodiment on the wall surface on which the concrete is placed will be described. In the housed state, the moving partition in the tunnel, which is normally folded and housed, is expanded to the floor surface, and then air or water is pressed into the tube 1 to gradually expand the tube 1 and form it into an annular shape. As the seat 5 spreads.

When the tube 1 expands to an annular shape to some extent, a moving partition in the tunnel is arranged along the radial cross section of the tunnel 2, and a fluid is further pressed into the tube 5. Expands and comes into close contact with the wall surface of the tunnel 5, and the sheet 5 formed integrally with the tube 1 spreads and acts as a curtain to partition the space inside the tunnel.

As described above, the partitioning device for moving in the tunnel according to the present embodiment can not only partition the space in the tunnel easily and in a short time, but also can prevent obstacles such as various pipes and entrances / exits in the tunnel. However, since the tube is an elastic body that can expand and contract, it can be deformed according to the shape of the obstacle, and high sealing performance can be realized.

As a result, the concrete curing section in the tunnel in which the concrete has just been cast is isolated from the outside, and the concrete wall surface that has just been cast is not exposed to a rapid temperature change due to the outside air, and good casting is achieved. The concrete is cured and it is possible to prevent the concrete from cracking. Also, noise and smoke generated in the tunnel can be shielded by this moving partition in the tunnel.

After the concrete is cured, it can be easily removed from the tunnel wall surface by discharging the fluid in the tube 1 to reduce the diameter of the tube 1, and it can be easily folded and moved to another place. Can be moved to. Moving in the tunnel The partition is made of rubber and plastic, which are thin and lightweight, making it extremely easy to carry.

[Effect of the invention]

 As described above, according to the present invention, an annular tube that expands by injecting a fluid such as air or water and closely adheres to the wall surface in the tunnel, and an annular tube that is provided integrally with this annular tube. Since it is equipped with a sheet that covers the enclosed inner space, it can be assembled quickly and easily along the radial cross section of the tunnel to isolate the concrete pouring section from the outside air and It is possible to prevent the exposed concrete from being exposed to a sudden temperature change with the outside air, and it is possible to perform good curing of the placed concrete.Even after the curing of the placed concrete is finished, it can be easily removed and carried easily. You can

According to the second aspect, since the annular tube is housed in the bag-shaped annular housing portion formed on the outer periphery of the seat, the tube and the seat can be easily integrated.

According to the third aspect of the invention, since the opening / closing port is provided at a predetermined position of the seat, the user can freely enter and exit the partitioned tunnel space.
