Is formed in the axial direction of the pipe body from the base of the receiving port 2 to the opening port 4 at the other end of the tubular body, and the depth 1 of the receiving port 2 is increased to provide the wart-like projection 5 at the abutting end portion thereof. Earthen pipe with groove and wart.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a conduit for ditches and warts for use in underdrain drainage works in a yard to convert wetlands into dry fields and introduce large-scale agricultural machinery.

[0002]

[Prior art]

 Conventionally, the pipe body used for the construction of this wetland into a dryfield has used unglazed earth pipes. When excavating, a trench ditcher called a trencher is used.

[0003]

[Problems to be solved by the device]

 The excavation by the trencher has a high excavation speed, and when burying a clay pipe, the work is carried out in the mud and mud caused by spring water, and as a result, the mud and mud are concentrated at the joints of the clay pipe and the construction is significantly hindered.

Even after the earth pipe is buried, the earth pipe becomes clogged with the mud and muddy water, and the drainage function is deteriorated. For this reason, it has been considered to provide a projection at the joint of the pipe body to provide a gap at the connecting portion of the clay pipe or to provide a groove for water conveyance on the surface of the clay pipe.

However, even if a clay pipe provided with this protrusion or a groove is merely changed in shape, if such a clay pipe is manufactured by hand, it is not In the case of the unfired clay pipe, the pipe is inevitably deformed due to movement or reversal.

For this reason, not only the water guiding performance of the groove provided on the surface of the pipe is deteriorated, but also the depth of the receiving port is shallow, so that the connection part will come off and the inflow of mud will be promoted after a certain period of time, and the passage due to the in-pipe accumulation Not only will the securing of the water profile be lost, but the drainage function will be lost.

[0007]

[Means for Solving the Problems]

 As a result of diligent research to solve such a drawback of the conventional drainage earth pipe, the inventor has made the groove formed on the surface of the pipe a semicircular cross section to reduce clogging of the groove and reduce water permeability. By improving the depth of the receiving port 1 to be deeper than that of the conventional one, the continuous connection is completed, and the wart-shaped projection is provided at the back end of this receiving port, and the automatic drainage is performed by fully automatic molding. It solves all the drawbacks of clay pipes.

[0008]

[Action]

 According to the present invention, the water guiding groove formed on the surface of the pipe body is formed into a semicircular shape having a small water guiding resistance to improve the water guiding ability, and the depth l of the receiving port is increased. The pipe will not be disconnected due to changes due to earthquakes, etc., and a wart-shaped protrusion is provided at the back end of the receiving port to form a gap at the connection part to prevent clogging by muddy water and always collect water constantly. It is effective.

Further, the present invention is intended to provide a high-performance earth pipe which is uncomparable to the conventional drainage earth pipe by eliminating the bending of the pipe body by automatically forming the pipe and improving the strength.

【Example】

 With reference to the attached drawings, the water conduit and the earth pipe with warts according to the present invention will be described. (1) is the whole earth pipe, and this earth pipe has a receiving port (2) for connection at one end, A water guiding groove (3) having a semicircular cross section is formed on the entire outer circumference in the axial direction of the pipe body from the base of the receiving port (2) to the opening port (4) at the other end of the pipe body.

In the clay pipe (1) of the present invention, the depth (1) of the receiving port (2) is set to be about 9 mm deeper than that of the conventional clay pipe, and the wart-like projection (5) is required on the contact surface at the rear end. The number (4 in the figure) is provided.

A feature of this earth pipe is that it is formed by a fully automatic pipe making machine, which allows the steps of drying and firing without touching the hands of workers. This prevents bending of pipes, crushing of grooves, and changes in the receiving port (2) without touching the uncured molded product, and a uniform product is always obtained, the initial effect is maintained and the strength is stable. Can be measured.

[0014]

[Effect of device]

 In the clay pipe of the present invention, the water guiding groove formed on the surface of the pipe body is formed into a semicircular shape with a low resistance to improve the water guiding ability, and the depth l of the receiving port is deepened so that the pipe phases drop out. In addition, by providing a wart-shaped projection at the back end of the receiving port, a gap is formed at the connection part to prevent clogging due to muddy water and always exhibit a stable water collection effect. It is possible to obtain an excellent effect of use, which is not seen in conventional drainage earth pipes, that can improve strength by eliminating bending and distortion of the pipe body.
