Description

[Detailed description of the invention] This invention is a wastewater treatment device at the end of a decorative and drip-preventing interior panel that is installed in a series from the ceiling to the side wall of the tunnel, for example, in order to repair an existing tunnel that does not have side gutters installed. It is related to.

When the interior board is installed, groundwater dripping from the ceiling flows down the back side of the interior board to both sides. Also, groundwater seeping from the side walls of the tunnel flows down the side walls.

Therefore, gutters are needed to collect the flowing water and drain it out of the tunnel, but the construction of the gutters is troublesome, takes many days, and is expensive because it uses a lot of materials.

The purpose of this proposal is to provide a wastewater treatment device with a structure that does not require the installation of side gutters and is easy to construct. Then, install the gutter 2 inside it, and then install it on the side wall W of the tunnel T.
The gist is that a drain plate 5 is provided to guide the water flowing along the wall W to the gutter 2.

The interior board 1 is constructed by sequentially stretching a large number of unit boards 1A along the arch direction and the extension direction of the tunnel T while overlapping their edges.

The unit plate 1A is made of painted steel plate, aluminum plate, etc., and its size is, for example, 2000 to 2400 m in length and 2400 m in width.
It is about 500-600m/m. Both ends in the vertical direction are bent into a Z-shaped cross section, and the groove bottom formed by overlapping the bent portions 1B is applied to the inner surface of the tunnel, and the fixing tool such as the anchor bolt 3 is inserted through the groove bottom. Enter and stop. Then, Figure 3・
As shown in FIG. 4, a gap G through which water passes is formed between each unit plate 1A and the inner surface of the tunnel.

In order to connect both hem portions of the interior panel 1 in a plane, bent portions having a substantially Z-shaped cross section are formed on both edges of the lower half of the unit panel 1A located at the lowest position, as shown in FIG. Not formed.

The cross section of the gutter 2 can be any shape such as concave shape or U shape.
The length of one piece is, for example, 4 m. While sequentially connecting these pieces, fit them onto the hem of the interior board 1 as shown in Figures 2 and 4, and rivet the front edge of the gutter 2 to the interior board 1. As the rivet 4, it is preferable to use a type called a pot rivet or a blind rivet, which can be fixed by operation from one side.

The edge of the gutter 2 on the tunnel wall side is the tunnel wall W
In order to correctly guide the water that comes into contact with the wall and flows along the wall to the gutter 2, a drain plate 5 is provided on the wall W as shown in FIG.

A drainage port 6 is provided at the lower end of the gutter 2 to lead to a drainage ditch outside the tunnel.

Since the present wastewater treatment device has the above-mentioned configuration, groundwater dripping from the ceiling S of the tunnel T flows down the back surface of the interior panel 1, and groundwater seeping out from the side wall W flows down the side wall W and further flows through the drain plate. 5, all of that water is collected in the gutters 2 on both sides and drained out of the tunnel T, so there is no need to install side gutters.

Since the gutter 2 is simply fixed to the hem of the interior board 1 with rivets, the work is easier and cheaper than gutter construction, and it is suitable not only for repairing existing tunnels but also for constructing new tunnels without side walls. It is effective even if it is implemented.

Claims (1)

[Scope of utility model registration request] This drainage treatment device is installed at the end of the tunnel interior panel, which is stretched continuously from the ceiling to the side wall of the tunnel, and has gutters riveted to the inside along both sides of the bottom of the interior panel to receive water flowing down the back side of the interior panel and direct it to the outside of the tunnel, and a water drain plate is installed parallel to the gutters at the bottom of the tunnel side wall to direct water flowing down the side wall of the tunnel to the gutters.
