Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a water collecting pipe that is buried underground to collect groundwater and the like.

[0002]

[Prior art]

 Conventionally, for example, a water collection pipe for draining groundwater is buried in the soil for the purpose of soil conservation, and groundwater is taken into the water collection pipe from multiple water holes provided on the outer surface of the water collection pipe, and rainwater is collected at the water collection pipe. Is drained to prevent soil erosion due to rainwater.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional example, groundwater is taken into the water collection pipe from a plurality of water holes provided on the outer peripheral surface of the water collection pipe.However, since the water collection pipe is directly buried in the ground, There is a problem that the soil is easily clogged and the water collection effect is reduced. In addition, since the water collection pipe is in direct contact with the sand and sand, corrosion such as rust has also progressed, and the durability is inferior.

The present invention is intended to solve such problems, and to provide a water collecting pipe which prevents clogging of water passage holes, enhances the water collecting effect, and has excellent durability. With the goal.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention embeds a water collecting pipe in the ground, forms a plurality of water passage holes on the outer peripheral surface of the water collecting pipe, and partially protrudes on the outer peripheral surface of the water collecting pipe. Is formed, the water collecting pipe is covered with an outer layer body having water permeability with the protruding part interposed, and a gap is formed between the outer layer body and the water collecting pipe.

[0006]

[Action]

 In the water collecting pipe of the present invention, when the water collecting pipe is buried in the ground, the outer layer blocks the sediment, and the water passage hole is not clogged by the sediment. In addition, the water holes provided in the water collection pipe open toward the void space, and the groundwater that permeates through the outer layer can be taken into the water collection pipe from the entire circumference of the water collection pipe, and the water collection pipe is also formed in the outer layer body. By covering with, it is possible to suppress the corrosion of the collecting pipe.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

1 to 3 show a first embodiment of the present invention, in which 1 is a water collecting pipe buried in the ground, and a plurality of water passage holes 2 are formed in the water collecting pipe 1. The water passage holes 2 are formed in an elongated rectangular shape along the water collection pipe 1, are provided at four locations on the same circumference at equal intervals, and have different steps along the longitudinal direction of the water collection pipe 1. It is formed in a staggered pattern. Reference numeral 3 denotes a bar member which is provided on the outer peripheral surface of the water collection pipe 1 and serves as a projecting portion. As shown in FIG. 2, this bar member 8 has eight bar members 3 along the longitudinal direction of the water collection pipe 1, etc. It is fixed so as to partially protrude by welding or the like at each interval. An iron wire 4 having a diameter of about 3 mm is spirally wound around the outer surface of each of the rods 3 at a pitch of about 75 mm, and an outer layer body covering the water collecting pipe 1 from above the iron wire 4 is formed. A net 5 made of nylon having a diameter of about 3 mm and a net 6 made of iron wire having a diameter of about 1.5 mm are wound. Then, in order to suppress the mesh bodies 5 and 6, a copper wire 7 having a diameter of about 1.5 mm is wound on the outer mesh 6. In this case, the iron wire 4 is spirally wound around the eight rods 3 partially projecting from the outer peripheral surface of the water collecting pipe 1, and the mesh bodies 5 and 6 are wound on the iron wire 4. As shown in FIG. 3, a gap A is formed between the inner net body 5 and the outer peripheral surface of the water collection pipe 1.

The water collecting pipe 1 configured as described above is buried in the ground for the purpose of soil conservation and the like. In the present invention, eight rods 3 are provided on the outer peripheral surface of the water collecting pipe 1. By partially projecting and covering the water collecting pipe 1 with two layers of nets 5 and 6 with the rod 3 interposed, when the water collecting pipe 1 is buried in the ground, Sediment is blocked, and there is no clogging of water holes 2 due to sediment. Moreover, since the gap A is formed by the rod 3 around the water collecting pipe 1, the water passage 2 is not blocked by the nets 5 and 6, and the water passage 2 becomes the space of the gap A. Since it opens facing, it is possible to efficiently take in the groundwater that permeates through the mesh bodies 5 and 6 from the water hole 2 into the water collection pipe 1, and in particular, the gap A is provided around the entire circumference of the water collection pipe 1. Since water can be collected from the entire circumference of the water pipe 1, its water collecting effect can be enhanced. Further, by covering the water collecting pipe 1 with the nets 5 and 6 made of two layers to block the earth and sand, corrosion of the water collecting pipe 1 can be suppressed and the durability of the water collecting pipe 1 can be enhanced. In addition, in the above-mentioned conventional example, the water collection effect is reduced due to the clogging due to the sand and sand.In order to enhance the water collection effect, as many water passage holes as possible should be provided. As described above, in order to increase the opening ratio of the water passage holes, since many water passage holes are densely formed, the strength of the water collection pipe itself tends to decrease. Since the excellent water collecting effect can be exhibited without forming the water holes 1 densely, the water holes 1 are provided in a staggered manner, and the strength of the water collecting pipes 1 itself is also increased. It can be increased, and in combination with the above corrosion prevention, its durability can be increased. FIG. 4 shows a second embodiment of the present invention. The same parts as those in the first embodiment are designated by the same reference numerals and detailed description thereof will be omitted.

In this example, instead of the nets 5 and 6 covering the water collecting pipe 1, the outer layer body is constituted by the pipe body 11 having a large number of holes 10 and having a diameter larger than that of the water collecting pipe 1. Then, the water collecting pipe 1 is inserted into the pipe body 11, and the pipe body 11 and the water collecting pipe 1 are connected by a connecting piece 12 serving as a protruding portion. Then, by collecting the pipe body 11 on the water collecting pipe 1 to form a double pipe structure and forming a space A between the pipe body 11 and the water collecting pipe 1, the water collecting pipe 1 is collected as in the first embodiment. When the pipe 1 is buried in the ground, the pipe 11 blocks the sediment, the clogging of the water passage hole 2 is not caused by the sand, and a space is formed around the water collection pipe 1 by the void A. The groundwater that permeates through the holes 10 can be efficiently taken from the water holes 2 into the water collection pipe 1 to enhance the water collection effect, and the pipe body 11 covering the water collection pipe 1 suppresses the corrosion of the water collection pipe 1. Therefore, the durability of the water collection pipe 1 can be improved.

The present invention is not limited to the above embodiments, and various modifications can be made. For example, although the outer layer body is constituted by a net body or a tubular body having a large number of holes, it may be any one having water permeability such as expanded metal or various knitted bodies, and in the first embodiment. Although the example in which the two-layer net body is provided is shown, the two-layer net body may be provided in one layer or two or more layers. Similarly, in the second embodiment, the double tube structure is shown. It may be a tube structure. Further, the shape and arrangement of the water passage holes formed in the water collection pipe may be set appropriately.
