Description

  The present invention relates to a water leaking gutter for guiding water leakage from a tunnel inner wall to a drainage portion.

  For example, when water leakage occurs on the inner wall of a tunnel or the like, as described in Patent Document 1, a water leakage prevention gutter (water leakage gutter) is attached along the water leakage portion, and the water leakage is received by the water leakage prevention gutter. The water is drained to the side grooves (drainage sections) on both sides of the tunnel.

The water leakage prevention ridge (water leakage ridge) is formed into a shallow square ridge shape, and is disposed along the inner wall of the concrete of the tunnel and has a packing integrally provided on both sides of the leakage prevention ridge. The both sides of the water leakage prevention gutter were fixed to the inner wall with a fixing tool such as a bolt.
Such a water leaking gutter is attached to the inner wall of the tunnel where the water leaks when water leaks on the inner wall of the tunnel.
Japanese Patent Laid-Open No. 10-37694

By the way, the water leakage from the tunnel inner wall is contaminated with earth and sand, organic matter, bacteria, etc., and these contaminants adhere to the inner surface of the water leakage trap and gradually increase or propagate. Since the water leakage jar is clogged, it is necessary to periodically remove the water leakage ridge from the inner wall surface of the tunnel and clean the inside of the water leakage ridge.
In order to remove the leaking dredging, it is necessary to remove all bolts and other fixtures that secure the leaking dredging, and if the leaking dredging is also fixed near the top of the inner wall of the tunnel, a scaffold is also required. As a result, it takes a lot of time and effort, and it also imposes a burden on the operator. Furthermore, after cleaning, it also takes time to fix the water leaking gutter to the tunnel inner wall again.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a water leakage bag that can be easily cleaned and prevented from clogging without removing the bag body from the inner wall of the tunnel.

In order to achieve the above object, the invention described in claim 1 is arranged along the tunnel inner wall 2 and guides water leaked from the tunnel inner wall 2 to the drainage part 17 as shown in FIGS. 1 for water leakage,
The main body 3 disposed along the inner wall 2 of the tunnel, and inserted into the main body 3 so as to be detachable so that contaminants such as earth and sand mixed in the water leakage can be captured and can be permeated. and a filter 4,
The filter 4 has a cross section substantially equal to a cross section inside the bag main body 3 .

Here, the filter may be made of entangled thin fibers made of synthetic resin, or a foamed resin having many fine cavities inside.
When this filter is inserted into and removed from the bag main body, an opening for inserting and removing the filter may be provided at the end or in the middle of the bag main body, and inserted through this opening. It is desirable to provide a lid for this opening.

  According to the first aspect of the present invention, since the water leaking gutter includes the gutter body and a filter that is removably inserted into the main body, water leaking from the inner wall of the tunnel flows through the filter in the gutter body. Contaminants such as earth and sand that flow and drain into the drainage part and are mixed in the leaked water are captured by the filter and are not discharged to the drainage part. When a certain amount of contaminants accumulates in the filter, pull this filter out of the 樋 body and insert a new filter into the 樋 body to easily clean the 樋 body without removing it from the tunnel inner wall. Can prevent clogging.

The invention as set forth in claim 2 is the water leakage bag according to claim 1,
The filter 4 includes a water-impermeable sheet 10 and a filter material 11 that is fixed to the sheet 10 and is capable of capturing contaminants such as earth and sand mixed in water leakage, and is permeable to water.
The sheet 10 has a higher tensile strength than the filter material 11.

Here, it is preferable that the sheet is provided so as to cover a surface other than the surface in contact with the inner wall of the filter material, that is, a surface facing the inner surface of the bag main body.
The sheet preferably has a smaller coefficient of friction with respect to the bag body than the filter material.

According to the second aspect of the present invention, when the filter is pulled out from the bag main body, the filter material is prevented from being broken or extended by grasping and pulling out the sheet, thereby facilitating the filter. And it can be pulled out reliably.
In addition, when pulling out an old filter that contains contaminants, the old filter is pulled out and the new filter is copied by connecting the front end of the next new filter to the rear end of the filter. The filter material can be easily and reliably pulled and inserted by preventing the filter material from being broken or extended into the body.

A lid 15 capable of opening / closing an insertion / removal port for inserting / removing the filter 4 into / from the bag main body is provided at an end of the bag main body 3.

  According to the third aspect of the present invention, since the lid that can open and close the insertion / removal opening is provided at the end of the main body, leakage of water from the inner wall of the tunnel is prevented by inserting the lid in the normal state. Prevents leakage from the outlet to the outside, ensuring that the water leaks to the drain, and when replacing the filter, the lid can be opened to easily replace the filter without removing the main body from the tunnel inner wall. .

The invention according to claim 4 is the water leakage jar according to any one of claims 1 to 3,
A connecting portion 12 for connecting the next filter to the filter 4 is provided at the end of the filter 4.

Here, the connecting portion may be, for example, a hook, a fastener, or the like, or may be a metal fitting that is detachably engaged with each other.
Moreover, as above-mentioned, when the filter is comprised from the water-impermeable sheet | seat and the water-permeable filter material fixed to this sheet | seat, the said connection part is provided in a sheet | seat.

  According to the invention described in claim 4, since the connection portion is provided at the end portion of the filter, when the old filter in which the contaminants are accumulated is pulled out from the bag body, the connection portion of the filter rear end portion is provided. By connecting the connection part of the next new filter tip, the old filter can be pulled out and at the same time, the new filter can be pulled and inserted into the bag body.

According to the present invention, the water leaking gutter includes a gutter body and a filter that is removably inserted into the main body, so that when a certain amount of contaminants accumulates in the filter, the filter is removed from the gutter body. By pulling out and inserting a new filter into the main body, the main body can be easily cleaned and prevented from becoming clogged without removing it from the inner wall of the tunnel.
In addition, by configuring the filter with an impermeable sheet and a filter material fixed to the sheet, the filter can be easily and reliably pulled out by grasping and pulling out the sheet. It can also be pulled and inserted into the bag body.
Furthermore, by providing a lid that can open and close the insertion / extraction opening at the end of the bag body, it is possible to prevent leakage of water from leaking out of the insertion / extraction opening, and to reliably drain the leakage to the drainage section, and open the lid. Therefore, the filter can be easily replaced without removing the main body from the inner wall of the tunnel.
Also, by providing a connection part at the end of the filter, the old filter can be replaced by connecting the connection part of the next new filter front end to the connection part of the old filter rear end part where contaminants have accumulated. At the same time as pulling out, a new filter can be pulled into the bag body.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view inside a tunnel showing a state in which a water leaking gutter 1 according to the present invention is arranged on a tunnel inner wall 2, and FIG. 2 is a transverse sectional view thereof.
In the present embodiment, the water leaking troughs 1 are configured in an arch shape along the tunnel inner wall 2 and are arranged at a predetermined interval in the tunnel axis direction.

As shown in FIGS. 2 to 4, the water leaking gutter 1 includes a gutter body 3 and a filter 4. The eaves body 3 has a substantially U-shaped cross section having flange portions 3a, 3a on both sides. The flange portions 3a, 3a are brought into contact with the tunnel inner wall 2 via a packing material 5, and a fixing material 6 such as a bolt or an anchor is provided. Is attached to the tunnel inner wall 2 by screwing it into the natural ground through the flange portion 3a and the packing material 5.
Further, as shown in FIG. 3, the heel body 3 is configured by connecting a plurality of heel members 7 in the longitudinal direction thereof, that is, in the circumferential direction of the tunnel. A waterproof tape or the like is attached to the portion, thereby preventing water leakage from the connection portion. In addition, in this example, since the coffin main body 3 is long so as to extend in the circumferential direction of the tunnel, the coffin main body 3 is configured by connecting a plurality of coffin structural bodies 7, but when the coffin main body 3 is short, For example, when water leaks from the side surface of the inner wall of the tunnel, the rod main body 3 may be short, and thus the rod main body 3 may be constituted by one relatively long rod structure.

The filter 4 is removably inserted into the main body 3 so as to be able to capture contaminants such as earth and sand mixed in the leaked water, and is permeable to water. The cross section of the filter 4 has a rectangular shape substantially equal to the cross section inside the bag main body 3, and has a length substantially equal to that of the bag main body 3.
Further, as shown in FIG. 4, the filter 4 includes an impermeable belt-like sheet 10 and a filter material 11 fixed to the sheet 10 with an adhesive or the like.
The sheet 10 is formed in a substantially U-shaped cross section, and is provided so as to cover a surface other than the surface in contact with the tunnel inner wall 2 of the filter material 11, that is, a surface facing the inner surface of the bag main body 3. Further, the sheet 10 is formed of a material having a higher tensile strength than that of the filter material 11 and a smaller coefficient of friction with respect to the inner surface of the bag body 3.

  The filter material 10 is capable of capturing contaminants such as earth and sand mixed in water leakage, and is permeable to water, for example, by entwining thin fibers made of synthetic resin into a belt shape, A water passage is formed through which water leakage can pass, and contaminants such as earth and sand mixed in the water leakage can be captured by thin fibers.

Since the filter 4 having the above-described configuration is substantially equal to the length of the heel body 3 and the cross-sectional shape is also substantially equal, the filter 4 is inserted into the heel body 3 without a gap. Further, as shown in FIG. 5, connection portions 12 are provided at both ends of the belt-like sheet 10 constituting the filter 4.
This connection part 12 is for connecting the filters 4 and 4 and is constituted by, for example, a hook-and-loop fastener.

Moreover, as shown in FIG. 3, the lid | cover 15 which can open and close the insertion / removal port which inserts / removes the filter 4 in / from the bag main body 3 is provided at both ends of the bag main body 3, respectively. The lid 15 is attached to the end of the bag body 3 by a hinge 16 so as to be opened and closed. When the lid 15 is closed, the insertion / removal port is closed in a watertight manner.
Both end surfaces of the main body 3 are opened, and a drainage portion 17 is installed below the both ends. The drainage part 17 is comprised by the U-shaped groove extended in the axial direction of a tunnel, for example, and discharges the water leaked in the water leaking gutter 1 comprised with the gutter body 3 and the filter 4 outside. It is like that.

The water leakage trough 1 configured as described above is attached to a portion of the tunnel inner wall 2 where water leakage has occurred. In this case, the filter 4 is previously inserted into the main body 3 of the water leakage main body 1 with the sheet 10 in contact with the inner surface of the main body 3. Then, as shown in FIG. 4, the flange portions 3 a and 3 a of the eaves body 3 are brought into contact with the tunnel inner wall 2 through the packing material 5, and the fixing material 6 such as a bolt or an anchor is grounded through the flange portion 3 a and the packing material 5. The leaking gutter 1 is attached to the tunnel inner wall 2 by screwing it into the mountain.
Water leaking from the inner wall of the tunnel flows through the filter material 11 of the filter 4 in the main body 3 and is drained to the drainage part 17, while contaminants such as earth and sand mixed in the water leak are captured by the filter material 11. Thus, it is not discharged to the drainage part 17.
When a certain amount of contaminants such as earth and sand accumulates on the filter material 11 of the filter 4, the used filter 4 is pulled out from the main body 3.

In this case, one of the lids 15 and 15 provided at both ends of the bag body 3 is opened, and the tip of the sheet 10 of the used filter 4 is grasped and pulled out. Open the other lid 15, and connect the connecting portion 12 provided at the front end portion of the sheet 10 of the next new filter 4 to the connecting portion 12 provided at the rear end portion of the sheet 10 of the used filter 4. Engage and connect (see FIG. 5).
Thereafter, when the tip of the sheet 10 of the used filter 4 is grasped and pulled out, the filter 4 is pulled out from the bag body 3 and the next new filter 4 connected to the rear end of the filter 4. Is pulled into the bag body 3 and inserted. Then, when the entire used filter 4 is pulled out of the bag main body 3, at the same time, a new entire filter 4 is inserted into the bag main body 3, whereby the replacement of the filter 4 is completed.

As described above, in the present embodiment, when a certain amount of contaminants accumulates in the filter 4, the used filter 4 is pulled out from the bag body 3 and a new filter 4 is inserted into the bag body 3. Without removing the main body 3 from the inner wall 2 of the tunnel, it can be easily cleaned to prevent clogging.
Further, since the sheet 10 of the filter 4 has a higher tensile strength than the filter material 11, when the filter 4 is pulled out from the bag body 3, the filter material 11 is broken or stretched by grasping and pulling out the sheet 10. The filter 4 can be easily and reliably pulled out by preventing it from being broken.
Further, the sheet 10 is provided so as to cover the surface of the filter material 11 that faces the inner surface of the bag main body 3, and the coefficient of friction with respect to the inner surface of the bag main body 3 is smaller than that of the filter material 11. Thus, the frictional force between the filter 3 and the filter 3 can be reduced, so that the filter 4 can be easily pulled out of the bag body 3.
Further, since the sheet 10 is provided so as to cover the surface of the filter material 11 that faces the inner surface of the bag body 3, contaminants such as earth and sand collected in the filter material 11 are not left in the bag body 3. .

Furthermore, since the connection part 12 is provided in the edge part of the filter 4, when pulling out the used filter 4 from the bag main body 3, the next new filter front-end | tip is connected to the connection part 12 of this filter rear end part. By connecting the connecting portion 12 of the part, the used filter 4 can be pulled out, and at the same time, a new filter 4 can be pulled and inserted into the bag body. Therefore, the filter can be replaced quickly. Even in this case, the filter material 11 of the new filter 4 is prevented from being broken or extended, and the new filter 4 can be easily and reliably pulled and inserted into the bag body 3.
Moreover, since the lid 15 capable of opening and closing the insertion / extraction opening is provided at the end of the main body 3, leakage from the inner wall of the tunnel leaks to the outside by closing the lid 15 in normal times. The water can be reliably drained to the drainage part 17, and the filter can be easily replaced without removing the main body 3 from the tunnel inner wall 2 by opening the lid 15 when replacing the filter.

In this embodiment, the water leaking trough 1 is arranged in an arch shape along the tunnel inner wall 2. However, the present invention is not limited to this, and the water leaking trough 1 may be appropriately provided at the water leaking location on the tunnel inner wall 2.
Moreover, in this Embodiment, the insertion / removal opening | mouth for the filter 4 was each provided in the both ends of the water leaking trough 1, and the lid | cover 15 which opens and closes this insertion / removal opening was provided. One or a plurality of water leaking troughs 1 may be provided. In this way, used portions of the filter 4 can be exchanged intensively. In that case, since it is necessary to know which part of the filter 4 is dirty, it is desirable to form the bag body 3 from a transparent material.
