Description

[Detailed description of the invention] [Field of industrial application] This invention is a water collection pipe that is buried underground and is used to collect water from surrounding strata or to sprinkle water inside the pipe. In particular, the present invention relates to a pipe for collecting and distributing water that is easy to assemble, is strong, and has improved water collection and dispersion performance.

[Prior Art] Conventionally, whether rainwater accumulates on the ground surface, it weakens the ground, and if the accumulated water flows only in one direction, it forms unexpected water flow areas, and the formation of strata weakens. Unexpected subsidence may occur if moisture is contained unevenly, so as a ground countermeasure, pipes with water holes or slits drilled in the surrounding wall of the pipe material are buried horizontally or vertically to prevent damage to the surrounding strata. Techniques have been developed to collect water from the ground and sprinkle water into the soil.

[Problem that the invention aims to solve] These pipes have round holes or slits drilled in the outer wall of the pipe material in order to allow water to pass between the surrounding strata and the inside of the pipe. The disadvantage is that it is easily clogged and the slit is structurally weak. In addition, in the case of slits, fins extending outward from the long edges are devised to guide water flow over a wide range, but the larger the area of the fins, the more likely they are to receive pressure from the strata, causing distortion. or damage may occur.

This invention was devised in view of these problems, and aims to have a strong structure and improve water collection and dispersion.
The purpose of the present invention is to provide a pipe for collecting and distributing water that is easy to assemble.

[Means for Solving the Problems] In the present invention, the measures taken to solve the above problems include a plurality of water passage slits along the longitudinal direction of the pipe material and one side of the water passage slits. A pipe for collecting and distributing water, which is formed with fins extending outward from a long edge, and has a pipe material formed with a raised part that projects inward, and a notch corresponding in shape and position to the raised part. A pipe material is placed between an internal reinforcing collar material provided and fitted onto the inner circumferential surface of the pipe material, and an internal reinforcing collar material that is in contact with the outer circumferential surface extending from a fin section of the tubing material to the next adjacent fin section. The pipe for collecting and distributing water is characterized by comprising an external reinforcing flange material to be held, and a screw member for communicating the external reinforcing flange material and the pipe material and fixing it to the internal reinforcing flange material.

[Function] If the material of the internal reinforcing collar material fitted inside the pipe material has sufficient rigidity, it will help maintain the shape of the pipe material for a long time, and there will be no space between the pipe material and the external reinforcing collar material. By sandwiching the tubes, it plays a role in assembling them firmly even if the tubes are not integrally formed. Further, for this purpose, a raised part is made to protrude from the inner circumferential surface of the tube material, and a notch corresponding to this raised part is provided in the internal reinforcing flange material to prevent displacement in the circumferential direction. Furthermore, an external reinforcing material is applied to the outer periphery of the pipe material and sandwiched between it and the internal reinforcing collar material,
Fixing with screws increases the degree of fixation. Then, when the external reinforcing flange material reaches the outer edge of the fin part,
Adjacent reinforcing flange members sandwich the fin portion from both sides to prevent shaking and distortion.

[Examples] Hereinafter, the present invention will be described in detail with reference to examples and the drawings.

FIG. 1 is a sectional view showing an example of a water collection and distribution pipe in which the present invention is implemented. In FIG. 1, the water collection and distribution pipe has a pipe material 1 and a notch corresponding in shape and position to a protrusion 1a protruding inward from the inner wall of the pipe material 1, and is fitted onto the inner circumferential surface of the pipe material 1. The inner reinforcing collar material 2 and the adjacent fin portions 1c extend from the outer ends of the fin portions 1c extending outward from the long edges on one side of each of the plurality of water passage slits 1b along the longitudinal direction of the pipe material 1.
an external reinforcing collar material 3 that is in contact with the outer circumferential surface extending to the outer end of the pipe material 3 and sandwiching the pipe material 1 between it and the internal reinforcing collar material 2;
and a screw member 4 which connects the external reinforcing collar material 3 and the tube material 1 and fixes it to the internal reinforcing collar material 2.

In this embodiment, the tube material 1 is formed with a partial circumferential body 11 that is vertically divided in the longitudinal direction of a circular tube, and the partial circumferential body 11 is moved in the circumferential direction. They are assembled together, and the gap between adjacent circumferential bodies is formed into a slit. Each partial circumferential body 11 is formed with a protruding portion 1a protruding from its inner wall surface, and a fin portion 1c extending radially outward from one circumferential edge, and the base of the fin portion 1c extends inwardly from the inner wall surface. It protrudes to form another raised portion 1d. The tip of this raised portion 1d is formed into a hook shape, and is adapted to be engaged with a corresponding notch in the internal reinforcing collar material. If these raised parts 1a and 1d are in the shape of a ridge over the entire length of the pipe material 1, they will strengthen the pipe material 1, but the pipe material 1
If emphasis is placed on elasticity, only the portions that contact the inner and outer collar bodies may be used.

If the tube material 1 is a partially circumferential body, even if they are gathered together in the circumferential direction, they cannot be integrated into the tube shape unless there is a member to connect and fix them. The flange body serves not only a reinforcing effect but also an assembly role.

When the raised portions 1a and 1d are fitted to the ridges 1a and 1d and the partial circumferential body 11 is fixed from the outside to the entire circumference of the internal reinforcing collar member 2, the tube 1 is assembled, and the partial circumferential body 11
The arc length of the circumferential surface is designed to be slightly shorter than forming the entire circumference of the internal reinforcing flange member 2, and the area between the two forms a desired water passage slit.

The edge extends along the fin portions of the partial circumferential body and the adjacent partial circumferential body to its outer ends, and spans between the two fin portions. In a portion where the band-like portion 3a covers the water passage slit, an embedded portion 3c that is fitted into the water passage slit is provided protruding inside the band-like portion 3a. In addition, this external reinforcing flange material 3 includes:
A screw member 4 that connects the belt-shaped portion 3a and the collar-shaped portion 3b.
A screw hole 3d is drilled for the purpose.

FIG. 5 is a perspective view showing an example of a water collection and distribution pipe completed by assembling each member of the above embodiment, and the pipe material 1 is assembled by gathering the six pieces of the partial circumferential surface body 11 in the circumferential direction. and each partial circumferential body 11
has a fin portion 1c extending radially outward, and a gap therebetween forms a water passage slit 1b. These partial circumferential bodies 11, as already explained,
a protruding portion (not shown) is provided on the inner wall and is fitted into a notch of the internal reinforcing flange material (not shown);
An external reinforcing flange material 3 is brought into contact with the corresponding position and fixed by screw members 4. The belt-shaped part 3a of the external reinforcing collar material 3 firmly holds the tube material 1 between it and the internal reinforcing collar material 2 to maintain the tube shape, and the collar-shaped part 3b holds the tube material 1 between it and the collar-shaped part of the adjacent circumferential body. The fins 1c of the fins 1c are tightly held and kept in an expanded state for a long period of time.
For example, water in the soil is collected in the pipe from the water slit 1b through the fin portion 1c, and in the case of watering, the water in the pipe is guided from the water slit 1b to the fin portion 1c and is widely released into the strata.
