Description

The present invention relates to a drainage basin repair member, an underground drainage facility, and a drainage basin repair method.

Traditionally, drainage buried underground has been known. Also, as an example of drainage, a public concrete machine is known. Public concrete is easily deteriorated or damaged by reacting with the components contained in the wastewater.

Therefore, as a method for repairing a deteriorated or damaged drainage basin, for example, Patent Document 1 discloses that a rehabilitation member for rehabilitating a drainage basin such as a public basin is used. This rehabilitation member is used for drainage with an invert formed on the bottom surface and a rising pipe portion rising from the peripheral edge of the invert. The rehabilitation member includes an invert portion rehabilitation member mounted on the invert and a tubular riser pipe portion rehabilitation member inserted into the riser pipe portion along the inner peripheral surface of the riser pipe portion. As a result, the invert can be rehabilitated by the invert portion rehabilitation member, and the rising pipe portion can be rehabilitated by the rising pipe portion rehabilitation member.

Patent No. 5739781

By the way, the public drainage, which is an example of drainage, is buried in the ground in advance, and when the building is constructed, for example, through the drainage pipe, drainage facilities such as toilets, baths, and kitchen sinks in the building. Connected to. Here, when the depth at which the drainage pipe is buried is shallow, the bottom is formed with an inflow port that opens to the side and an outflow port that opens to the side and is located below the inflow port. A public basin with a tubular body and an invert formed on the bottom of the body may be used. In such a public area, the drainage that flows in from the inlet flows like a waterfall and is struck by the invert. Therefore, public inverts are particularly vulnerable to deterioration or damage.

Therefore, if a public tub that flows like a waterfall and is deteriorated or damaged is repaired using the rehabilitation member disclosed in Patent Document 1, it will flow into the main body from the inflow port. The drainage was easily scattered because it was struck against the bottom of the rehabilitation member. In addition, due to the scattering of wastewater, the filth contained in the wastewater sometimes remained in the main body.

The present invention has been made in view of this point, and an object thereof is to be able to suitably repair a deteriorated or damaged drainage basin, and to smoothly drain the drainage into the drainage basin after the repair. It is possible to provide drainage basin repair materials, underground drainage facilities, and drainage basin repair methods.

The drainage basin repair member according to the present invention includes a bottomed tubular body having an inflow port that opens sideways and an outflow port that opens sideways and is located below the inflow port. It is a repair member for the drainage cylinder provided. The repair member includes a drainage receiving portion and a repair invert. The drainage receiving portion receives the drainage that has flowed into the main body from the inlet of the drainage basin, and is formed in a circular shape in a plan view. One end of the repair invert is connected to the drainage receiving portion, the other end is connected to the outlet of the drainage basin, and the repair invert is inclined downward from one end toward the other end.

According to the repair member, the repair member is increasingly arranged in the main body so that the other end of the repair invert is connected to the outlet of the drainage basin. At this time, a space is formed between at least a part of the drainage receiving portion of the repair member and the bottom surface of the main body. Therefore, even if the bottom of the main body is deteriorated or damaged and a step is formed on the bottom of the main body, the repair member can be more appropriately arranged in the main body without being affected by the above step. .. Therefore, the deteriorated or damaged drainage can be suitably repaired by using the repair member. Further, the vertical distance between the drainage receiving portion of the repair member and the inflow port of the drainage basin is shorter than the vertical distance between the bottom surface of the drainage basin and the inflow port, for example. Therefore, the drainage that has fallen from the inflow port to the drainage receiving portion is difficult to scatter.

According to a preferred aspect of the present invention, the drainage receiving portion is curved so as to be recessed downward. One end of the repair invert is connected to the bottom of the drainage receiving portion.

According to the above aspect, since the drainage receiving part is curved so as to be recessed downward, when the drainage is repaired by the repair member, the drainage that has flowed into the main body from the inflow port is received by the drainage receiving part. After that, it is easy to flow toward the repair invert. Therefore, it is possible to prevent the drainage from accumulating in the drainage receiving portion.

According to another preferred embodiment of the present invention, it is provided with an insertion portion which is continuous with the other end of the repair invert and is inserted into the outlet of the drainage basin.

According to the above aspect, the repair member is further arranged in the main body with the insertion portion inserted into the outlet of the drainage basin. As a result, when repairing the drainage drainage using the repair member, the repair member can be made more difficult to shift with respect to the main body, and the repair member becomes more difficult to swing with respect to the main body. In addition, by inserting the insertion part into the outlet, it becomes easier to align the repair member with respect to the main body. Further, when the drainage is repaired by using the repair member, the drainage can be prevented from leaking from between the outlet and the repair invert.

According to another preferred embodiment of the present invention, the guide portion extends downward from the edge of the drainage receiving portion.

According to the above aspect, when the repair member is placed in the main body, the guide portion of the repair member functions as a guide when the repair member is inserted into the main body along the inner peripheral surface of the main body. Therefore, the guide portion makes it easier to insert the repair member into the main body. If the guide portion extends upward from the edge of the drainage receiving portion, filth or the like contained in the drainage may adhere or accumulate on the guide portion. However, in the above aspect, since the guide portion is not located above the drainage receiving portion, it is possible to prevent dirt and the like from adhering or accumulating on the guide portion.

According to another preferred aspect of the present invention, the drainage receiving portion is divided into a first member of the inlet side portion and a second member of the outlet side portion.

According to the above aspect, when repairing the drainage using the repair member, for example, after the second member is placed in the main body, the first member is placed in the main body. As a result, for example, it is easier to arrange the repair member in the main body as compared with the case where the repair member formed by one member is arranged in the main body.

According to another preferred embodiment of the present invention, one end of the repair invert is connected to the second member.

For example, if one end of the repair invert is connected to the first member and the second member, drainage may leak from the repair invert. However, according to the above aspect, one end of the repair invert is connected to the second member. Therefore, it is possible to prevent the drainage from leaking from the repair invert.

According to another preferred aspect of the present invention, the second member is provided with a mounting portion on which a part of the end portion of the first member is mounted.

According to the above aspect, when repairing the drainage using the repair member, the first member and the second member are in a state where a part of the end portion of the first member is mounted on the mounting portion of the second member. The members are increasingly placed within the body. Therefore, it is difficult to create a gap between the first member and the second member, and it is difficult for drainage to leak from between the first member and the second member.

The underground drainage facility according to the present invention includes any of the above-mentioned drainage basin repair members and the drainage basin. The drainage basin is buried underground. The drainage basin is formed on the bottom surface of the main body and has an invert having one end located below the inlet and the other end connected to the outlet. The repair member is arranged inside the main body so that the other end of the repair invert is in contact with the invert.

According to the underground drainage facility, since the other end of the repair invert of the repair member is in contact with the invert of the drainage basin, the repair member can be more stably arranged in the main body. Therefore, it is possible to provide an underground drainage facility in which repair members are stably arranged in the main body.

According to a preferred embodiment of the present invention, the main body is made of concrete.

According to the above aspect, the main body is made of concrete, and the concrete easily deteriorates by reacting with the components contained in the wastewater, and may be damaged by a load from the ground or the like. Therefore, since the concrete body is easily deteriorated or damaged, it is particularly useful for the concrete body to be repaired by using a repair member.

The method for repairing the drainage basin according to the present invention is a method for repairing the drainage basin using the above-mentioned drainage basin repair member. The repair method includes a first placement step, a second placement step, and an injection step. In the first arrangement step, the second member is arranged inside the main body so that the other end of the repair invert is connected to the outlet. In the second arrangement step, the first member is arranged inside the main body so that a part of the end portion of the first member is placed on the previously described placing portion of the second member. In the injection step, a bonding agent is injected between the first member and the second member, between the first member and the main body, and between the second member and the main body. ..

By arranging the repair member inside the main body according to the process such as the repair method, the repair member can be appropriately arranged inside the main body. Then, by injecting a bonding agent between the first member and the second member, between the first member and the main body, and between the second member and the main body, the drainage that has flowed into the main body is increasing. Is hard to leak.

However, these directions are merely the directions determined for convenience of explanation, and do not limit the installation mode of the drainage drainage 10 and the repair member 30 at all.

The drainage drainage 10 according to this embodiment is a so-called public wastewater. As shown in FIG. 3, the drainage drainage 10 further includes a main body 11 and an invert 14. The main body 11 is a bottomed cylinder. The shape of the main body 11 is not particularly limited, but is, for example, substantially cylindrical. In the present embodiment, the main body 11 is composed of a plurality of members (here, three members), but may be integrally formed. Here, an inspection port 21 opened upward is formed at the upper part of the main body 11. Although not shown, for example, a standing pipe extending upward is connected to the inspection port 21, and a lid is fitted on the upper end surface of the standing pipe.

In the present embodiment, as shown in FIG. 2, the inflow port 12 and the outflow port 13 are formed in the main body 11. Drainage from the outside flows into the inflow port 12. The inflow port 12 is formed on the side of the main body 11 and opens toward the side. Specifically, the inflow port 12 is formed at a portion of the side surface of the main body 11 above the vertical center of the side surface of the main body 11. In the present embodiment, the inflow pipe 5 connected to a drainage facility (not shown) such as a toilet, a bath, a kitchen sink, and a gutter is fitted into the inflow port 12.

The drainage in the main body 11 flows out from the outlet 13. The outlet 13 is formed on the side of the main body 11 and opens toward the side. In this embodiment, the outlet 13 is located below the inlet 12. Specifically, the outlet 13 is formed at a portion of the side surface of the main body 11 below the vertical center of the side surface of the main body 11 (here, the lower end portion). In a plan view, the outlet 13 faces the inlet 12. In the present embodiment, the outflow pipe 6 connected to the sewage main (not shown) is fitted into the outflow port 13.

Drainage is drained by the repair member 30. Drainage flows through the invert 14 in a state where the drainage 10 is not repaired. As shown in FIG. 3, the invert 14 is a groove formed on the bottom surface of the main body 11. In the present embodiment, in a plan view, the invert 14 is a linear groove extending from the inlet 12 to the outlet 13, and is a groove having a substantially half-pipe shape. In this embodiment, an inclined surface 22 is formed on the inner peripheral surface of the main body 11 and in front of and behind the invert 14. The inclined surface 22 is inclined downward from the inner peripheral surface of the main body 11 toward the invert 14.

In the present embodiment, the members constituting the drainage basin 10 are made of concrete. That is, the members constituting the main body 11, the invert 14, and the inclined surface 22 are each made of concrete. However, a part of the members constituting the drainage basin 10 may be made of a material other than concrete.

The wastewater 10 according to the present embodiment may be eroded and deteriorated by corrosive gas or deposits contained in the wastewater after long-term use. Alternatively, the drainage drainage 10 may be damaged due to land subsidence or a load from the ground. In particular, the drainage that has flowed into the main body 11 from the inflow port 12 directly hits the portion of the invert 14 on the inflow port 12 side. Therefore, the portion of the invert 14 on the inflow port 12 side is liable to deteriorate. In this way, if the drainage basin 10 is deteriorated or damaged, the drainage and odor in the drainage basin 10 may leak to the outside. Therefore, in the present embodiment, in order to suppress the leakage of drainage and odor, the deteriorated or damaged drainage basin 10 is repaired by using the repair member 30.

Here, as described above, the outflow pipe 6 is fitted into the outflow port 13, and the insertion portion 34 is inserted into the outflow pipe 6. In the present embodiment, the insertion portion 34 is provided at the other end of the repair invert 33. As shown in FIG. 8, in a plan view, the insertion portion 34 projects laterally (here, to the left) from the edge of the drainage receiving portion 31. Here, the insertion portion 34 is formed in a cylindrical shape, but the shape of the insertion portion 34 is not particularly limited. The outer diameter of the insertion portion 34 and the inner diameter of the outflow pipe 6 are substantially the same. Specifically, in a state where the insertion portion 34 is inserted into the outflow pipe 6 fitted in the outflow port 13, the outer peripheral surface of the insertion portion 34 is in contact with the inner peripheral surface of the outflow pipe 6. A insertion inclined surface 41 is formed at the tip of the insertion portion 34 so as to be inclined toward the center of the insertion portion 34 toward the tip. This makes it easier to insert the insertion portion 34 into the outlet 13.

In the present embodiment, as shown in FIG. 1, the drainage receiving portion 31 is divided into a plurality of members. The number of members to which the drainage receiving portion 31 is divided is not particularly limited. Here, the drainage receiving portion 31 is divided into two members, a first member 51 and a second member 52. The first member 51 constitutes a portion of the drainage receiving portion 31 on the inflow port 12 side when the repair member 30 is arranged in the drainage tank 10. The second member 52 constitutes a portion of the drainage receiving portion 31 on the outlet 13 side when the repair member 30 is arranged in the drainage tank 10. In the present embodiment, the second member 52 is arranged on the left side of the first member 51. Here, in a plan view, the area S1 of the first member 51 is smaller than the area S2 of the second member 52. However, the area S1 of the first member 51 may be the same as the area S2 of the second member 52, or may be larger than the area S2 of the second member 52. In the present embodiment, in a plan view, the end of the first member 51 on the second member 52 side and the end of the second member 52 on the first member 51 side are linear ends, respectively, however, the first. The shape of the end of the member 51 on the second member 52 side and the end of the second member 52 on the first member 51 side are not particularly limited as long as they match. For example, in a plan view, at least a part of the end of the first member 51 on the second member 52 side and the end of the second member 52 on the first member 51 side may be curved.

In the present embodiment, as shown in FIG. 7, the repair invert 33 is provided on the second member 52, and is not provided on the first member 51 as shown in FIG. Here, as shown in FIG. 7, the repair invert 33 is integrally formed and is not composed of a plurality of members. As shown in FIGS. 5 and 9, the guide portion 32 is formed by being divided into a first member 51 and a second member 52.

Here, as shown in FIG. 8, a mounting portion 53 is formed at an end portion (here, the right end portion) of the second member 52 on the side in contact with the first member 51. The mounting portion 53 has a plate shape protruding from the second member 52 toward the first member 51 side (from left to right in FIG. 8). An end portion (here, a left end portion) of the first member 51 that comes into contact with the second member 52 is mounted on the mounting portion 53. Specifically, as shown in FIG. 6, a stepped mounting portion 54 recessed upward from the back surface is formed on the back surface of the end portion of the first member 51 that comes into contact with the second member 52. When the mounting portion 54 is mounted on the mounting portion 53 of the second member 52, the second member 52 is in a state of supporting the first member 51.

The material of the repair member 30 is not particularly limited. For example, the repair member 30 is made of resin. Specifically, the drainage receiving portion 31 (first member 51 and second member 52), the guide portion 32, the repair invert 33, and the insertion portion 34 of the repair member 30 are made of resin. However, at least a part of the drainage receiving portion 31, the guide portion 32, the repair invert 33, and the insertion portion 34 may be formed of a material other than the resin.

Next, a repair method for repairing the drainage drainage 10 using the repair member 30 will be described. The repair method according to the present embodiment includes a first placement step, a second placement step, and an injection step. First, in the first arrangement step, the second member 52 of the repair member 30 is arranged in the main body 11 of the drainage machine 10. Here, as shown in FIG. 2, the second member 52 is further arranged in the main body 11 so that the insertion portion 34 is inserted into the outlet 13 of the drainage basin 10. At this time, a part of the other end of the repair invert 33 comes into contact with the invert 14 of the drainage drain 10. Further, although not shown, the lower end of the guide portion 32 provided on the second member 52 is in contact with the upper end portion of the inclined surface 22 of the drainage drainage 10. After arranging the second member 52 in the main body 11, a bonding agent may be applied between the insertion portion 34 and the outflow pipe 6. At this time, the bonding agent applied between the insertion portion 34 and the outflow pipe 6 is, for example, mortar, but is not limited to mortar.

Next, in the second arrangement step, the first member 51 of the repair member 30 is further arranged in the main body 11. Here, as shown in FIG. 2, the mounted portion 54 of the first member 51 is mounted on the mounting portion 53 of the second member 52, and as shown in FIG. 1, the second member 52 is mounted. The first member 51 is arranged in the main body 11 so that the first member 51 is arranged on the right side of the main body 11. At this time, the lower end of the guide portion 32 provided on the first member 51 is in contact with the upper end portion of the inclined surface 22 of the drainage basin 10.

As described above, in the first arrangement process and the second arrangement process, the repair member 30 is increasingly arranged in the main body 11. Next, in the injection step, the first member 51 and the second member 52, the first member 51 and the main body 11 and the second member 52 and the main body 11 are joined using a bonding agent. Here, as shown in FIG. 1, the region AR1 including the space between the first member 51 and the second member 52, the space between the first member 51 and the main body 11, and the second member 52 are used. The bonding agent is injected into the region AR2 including the space between the main bodies 11. The type of bonding agent used is not particularly limited. In the present embodiment, the adhesive which is an example of the adhesive is injected into the region AR1 including the space between the first member 51 and the second member 52. As a result, there is no gap between the first member 51 and the second member 52, and the first member 51 and the second member 52 are fixed to each other. A mortar, which is an example of a bonding agent, is injected into the region AR2 including the space between the first member 51 and the main body 11 and the space between the second member 52 and the main body 11. As a result, the gap between the first member 51 and the main body 11 and the gap between the second member 52 and the main body 11 are eliminated, and the first member 51 and the second member 52 are further increased to the main body 11. Is fixed to.

By following the above steps, the drainage 10 can be repaired using the repair member 30. As shown in FIG. 2, when the drainage 10 is repaired by the repair member 30, a space 55 is formed between the drainage receiving portion 31 of the repair member 30 and the invert 14 of the drainage 10. It becomes.

In the drainage basin 10 repaired by the repair member 30, the drainage flows as follows. First, the drainage discharged from the drainage facility flows through the inflow pipe 5 and flows into the main body 11 from the inflow port 12. The drainage that has flowed into the main body 11 from the inflow port 12 falls to the drainage receiving portion 31 due to its own weight. Then, the drainage that has fallen to the drainage receiving portion 31 flows to the repair invert 33 and flows out from the outlet 13. The drainage discharged from the outflow port 13 is discharged to the sewage main (not shown) connected to the outflow pipe 6 through the outflow pipe 6.

As described above, in the present embodiment, the repair member 30 is further arranged in the main body 11 so that the other end of the repair invert 33 of the repair member 30 is connected to the outlet 13 of the drainage drainage 10. At this time, a space 55 is formed between the drainage receiving portion 31 of the repair member 30 and the bottom surface of the main body 11. Therefore, even if the bottom of the main body 11 is deteriorated or damaged and a step is formed on the bottom of the main body 11, the repair member 30 is appropriately arranged in the main body 11 without being affected by the above step. can do. Therefore, the repair member 30 can be used to suitably repair the deteriorated or damaged drainage drainage 10.

Further, in the drainage basin 10 repaired by the repair member 30, the drainage that has flowed into the main body 11 from the inflow port 12 falls to the drainage receiving portion 31 arranged above the invert 14 of the drainage basin 10. Therefore, as compared with the case where the drainage flowing from the inflow port 12 falls to the invert 14, the drainage basin 10 repaired by the repair member 30 is less likely to scatter the drainage in the main body 11.

In the present embodiment, the drainage receiving portion 31 is curved so as to be recessed downward. Here, the drainage receiving portion 31 has a substantially bowl shape. One end of the repair invert 33 is connected to the bottom of the drainage receiving portion 31. As a result, when the drainage 10 is repaired by the repair member 30, the drainage that has flowed into the main body 11 from the inflow port 12 is easily received by the drainage receiving portion 31 and then easily flows toward the repair invert 33. Therefore, it is possible to prevent the drainage from accumulating in the drainage receiving portion 31.

In the present embodiment, the insertion portion 34 which is continuous with the other end of the repair invert 33 and is inserted into the outlet 13 of the drainage basin 10 is provided. As a result, the repair member 30 is further arranged in the main body 11 with the insertion portion 34 inserted into the outlet 13 of the drainage drainage 10. Therefore, when the drainage drainage 10 is repaired by using the repair member 30, the repair member 30 can be made more difficult to shift with respect to the main body 11. In the present embodiment, since the outer diameter of the insertion portion 34 and the inner diameter of the outflow pipe 6 are substantially the same, the repair member 30 is more difficult to swing with respect to the main body 11 and outflows from the insertion portion 34. The tube 6 can be brought into close contact with the tube 6 more firmly. Further, by inserting the insertion portion 34 into the outlet 13, it is easier to align the repair member 30 with respect to the main body 11. Further, when the drainage drainage 10 is repaired by using the repair member 30, the drainage can be prevented from leaking from between the outlet 13 and the repair invert 33.

In the present embodiment, as shown in FIG. 1, the drainage receiving portion 31 is divided into a first member 51 on the inflow port 12 side portion and a second member 52 on the outflow port 13 side portion. As a result, when repairing the drainage 10 using the repair member 30, in the present embodiment, after the second member 52 is arranged in the main body 11, the first member 51 is further arranged in the main body 11. do. As a result, for example, it is easier to arrange the repair member 30 in the main body 11 as compared with the case where the repair member formed by one member is arranged in the main body 11.

Further, in the present embodiment, as shown in FIG. 7, one end of the repair invert 33 is connected to the second member 52. As shown in FIG. 4, the repair invert 33 is not connected to the first member 51. If one end of the repair invert 33 is connected to the first member 51 and the second member 52, drainage may leak from the repair invert 33.

In the present embodiment, as shown in FIG. 2, the repair member 30 is arranged inside the main body 11 so that the other end of the repair invert 33 is in contact with the invert 14 of the drainage basin 10. As a result, since the other end of the repair invert 33 of the repair member 30 is in contact with the invert 14 of the drainage basin 10, the repair member 30 can be more stably arranged in the main body 11.

In this embodiment, the main body 11 is made of concrete. Concrete easily deteriorates by reacting with components contained in wastewater, and the concrete main body 11 may be damaged by a load from the ground or the like. Therefore, since the concrete main body 11 is easily deteriorated or damaged, it is particularly useful for the concrete main body 11 to be repaired by using the repair member 30.

The repair method according to the present embodiment includes a first placement step, a second placement step, and an injection step. In the first arrangement step, the second member 52 is arranged inside the main body 11 so that the other end of the repair invert 33 is connected to the outlet 13. In the second arrangement step, the first member 51 is further arranged inside the main body 11 so that the mounting portion 54 of the first member 51 is mounted on the mounting portion 53 of the second member 52. Then, in the injection step, the bonding agent is injected between the first member 51 and the second member 52, between the first member 51 and the main body 11, and between the second member 52 and the main body 11. do. By arranging the repair member 30 inside the main body 11 along such a process, the repair member 30 can be appropriately arranged inside the main body 11. Then, by injecting a bonding agent between the first member 51 and the second member 52, between the first member 51 and the main body 11, and between the second member 52 and the main body 11. The drainage that has flowed into the main body 11 can be prevented from leaking.

For example, in the drainage basin 10, there is a risk that the portion around the outlet 13 may be cracked or damaged by long-term use. In the present embodiment, the bonding agent is injected between the repair member 30 and the main body 11 with the insertion portion 34 inserted into the outlet 13. Therefore, the portion around the outlet 13 that has been cracked or damaged can be repaired with the above-mentioned bonding agent.

In the above embodiment, the drainage receiving portion 31 is divided into two members, a first member 51 and a second member 52. However, the number of members that divide the drainage receiving portion 31 is not limited to two, and may be three or more. Further, the drainage receiving portion 31 may be formed by one member.

In the above embodiment, when the drainage 10 is repaired using the repair member 30, a space 55 (see FIG. 2) is formed between the drainage receiving portion 31 of the repair member 30 and the invert 14 of the drainage 10. It had been. However, a bonding agent such as mortar may be injected into the space 55.
