Abstract

(57) [Summary] [Problem] It has the advantage that the stability when installed is good, it does not roll over, the seam between the earth pipes is not easily displaced, and the burial work is easy, and the underground water is filled in. It is easy to penetrate, it is made longer by that amount,
Provided is an earthen pipe capable of improving productivity in manufacturing. The present invention is characterized in that ribs 2 extending in the longitudinal direction are radially protruded at a plurality of circumferential positions on the outer peripheral surface of the clay pipe main body 1, and water absorbing holes 3 are formed at arbitrary positions on the circumferential wall of the clay pipe main body 1.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an earthen pipe used for constructing a drainage culvert and the like.

[0002]

[Prior art]

 Conventional earthen pipes have a cylindrical shape. For example, when earthen pipes are placed on a wide bottom surface of a trench excavated with a yumbo or the like, they are likely to roll over and shift at a joint between the earthen pipes. In addition, although underground water is allowed to penetrate through the gap between the soil pipes and the seam between the soil pipes, if the length of the soil pipe is lengthened, the amount of water penetration into the ground decreases.

[0003]

[Problems to be solved by the invention]

 Therefore, the present invention has the advantage that the stability when installed is good, it does not roll over, the seam between the clay pipes is not easily displaced, and the burial work is easy, and the underground water can be easily soaked in, It is an object of the present invention to provide a clay pipe that can be lengthened accordingly to improve the work efficiency of burial work and improve productivity in manufacturing.

[0004]

[Means for Solving the Problems]

 In order to solve the above problem, the clay pipe of the present invention has a plurality of circumferentially continuous ribs 2 protruding radially at a plurality of circumferential positions on an outer peripheral surface of the clay pipe main body 1 and an arbitrary portion of a circumferential wall of the clay pipe main body 1. A water absorbing hole 3 is formed in the hole.

[0005]

[Action]

 The provision of the ribs 2 improves the stability and prevents rollover. In addition, the provision of the water absorption holes 3 in the peripheral wall does not reduce the amount of water seeping from the ground even if the length is reduced and the number of seams is reduced.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment of the present invention shown in the figure is formed entirely of clay, and has ribs 2 that are continuous in the longitudinal direction at five circumferential locations on the outer peripheral surface of a cylindrical clay pipe main body 1. In addition to projecting radially, a plurality of water absorption holes 3 are formed at regular intervals in the longitudinal direction at respective intermediate points between the ribs 2 on the peripheral wall of the clay pipe main body 1.

[0007] The material of the earthen pipe is not limited to clay, but can be molded using plastic or other materials.

Further, the number of the ribs 3 is not limited to five, but is arbitrary.

Further, the arrangement and number of the water absorption holes 3 are not limited to those shown in the figure, but are arbitrary.

As shown in FIG. 2, the earthen pipe is buried in a trench 4 excavated with a yumbo (not shown) or the like to construct a culvert 5.

[0011]

[Effect of the invention]

 The clay pipe of the present invention is as described above. Since the rib 2 is present at the bottom of the groove, it does not roll over, and the seam between the clay pipe and the clay pipe is less likely to be displaced. In addition, since the water in the ground penetrates through the water absorption holes 3 provided in the peripheral wall of the clay pipe main body 1, the length of the clay pipe reduces the amount of water seeping even if the joint between the clay pipes decreases. There is no. Therefore, it can be made longer than the conventional earthen pipe, which can improve the work efficiency of the burial work and also improve the productivity in the case of manufacturing.
