Abstract

(57) [Summary] [PROBLEMS] To provide a new underdrain water collecting pipe with a devised connection method and a joint tool therefor. SOLUTION: A joint tool having a short cylindrical shape is slidably fitted around an end of a culvert water collecting pipe main body.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 TECHNICAL FIELD The present invention relates to an earthen pipe provided with a joint tool for maintaining a connected state of a culvert drainage pipe, a culvert drainage pipe, and the joint tool.

[0002]

[Prior art]

 Conventional culvert construction work has been completed by simply lining up the culvert drainage pipes at the bottom of the ditch and lining them up in a row, then pouring earth and sand onto it and filling the ditch.

[0003]

[Problems to be solved by the invention]

 In the case of the construction work described in the above prior art, since the end faces are merely butted, a gap is easily generated between the butted ends of the culvert drainage pipes when earth and sand are charged, and the meticulous care is taken. Attention must be paid, and there are also problems such as the relatively large number of defective works that overlook the occurrence of misalignment.

[0004] An object of the present invention is to provide a new culvert water collecting pipe effective for solving the above-mentioned problems and a joint tool therefor.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the culvert drainage pipe according to the present invention is formed by slidably covering a joint member having a short cylindrical shape fired with clay around an end of the culvert drainage pipe main body. .

[0006] Similarly, the joint device of the culvert drainage pipe according to the present invention is used by being slidably fitted around the end of the culvert drainage pipe main body and having a short cylindrical shape. It is.

[0007]

[Function] The culvert drainage pipe according to the present invention is provided with a joint tool, and the culvert drainage pipe joint tool according to the present invention is provided as a single item so that it can be attached to a culvert drainage pipe on hand and used on site. .

[0008]

[Effect of the invention]

 The culvert drainage pipe according to claim 1 is formed by slidably covering a joint member having a short tubular shape around the end of the culvert drainage pipe main body. After the end faces of the culvert collecting pipe main bodies are abutted against each other as shown in the above, the joint tool located at the position indicated by the solid arrow at point A in the figure is slid to the position indicated by the imaginary line at point B at the above outlined arrow. If the culverts are used in such a way as to connect the culvert drainage pipes to each other, it is possible to completely eliminate the above-mentioned problems such as the occurrence of misalignment and to greatly improve the work. The culvert drainage pipe jointing tool according to Item 2 is used by being slidably fitted around the end of the culvert drainage pipe main body, and has a short cylindrical shape. Culvert drainage pipe Be one that can be fully achieved similarly eliminate occurrence problem shift be used in the same way as the usage according to Claim 1 After slipped, are both greater practical effect.
