本発１１は埋立地の雨水の集排水に用いる排水管路に関
するものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention 11 relates to a drainage pipe used for collecting and draining rainwater from a landfill.
〈従来の技術〉

Water collection branch pipes 21' are installed at regular intervals along the ihi.
. . . and 22', . . . are connected, and water collection branch pipes 21' . . . and 22', .
A system is known in which rainwater collected in a drain pipe I' is made to flow into a main drainage pipe I' and then discharged into a ditch, a river, the sea, etc.

大となるので、主管路が沈下して接続箇所に水漏れ事故
が発生し易くなる。However, in this drainage pipeline, there are a large number of water collection branch pipes connected to the main drainage pipe, and the inflow water that enters the earthen pipe through the water collection branch pipes is The downstream side of the main pipeline will be full of water. In the case of a wide area such as an airport landfill, pipes of various diameters must be prepared for the main pipe, and if the downstream side of the earthen pipe becomes full of water, the amount of water will flow to the bottom of the main pipe. This acts as a considerable load on the adjacent reclaimed earth and sand, and the stress per unit area, that is, the pressure, becomes large, making it easy for the main pipe to sink and water leakage to occur at the connection point.
更に、該主管路の口径増大は、導水勾配の関係で理立深

である。更に、重量が重いため、地耐力を十分に確保し
なければならず、工事費がかさむといった問題がある。Furthermore, increasing the diameter of the main pipe requires increasing the cutting depth due to the water conduction gradient, leading to an increase in construction costs. Therefore, in the case of concrete box culverts, we use horizontal double or triple culverts, but it is difficult to install the water collection branch pipes on site, and A communication hole must be drilled in the partition wall of the box culvert, which not only poses problems in terms of strength but also is difficult to construct. Furthermore, since it is heavy, sufficient soil bearing capacity must be ensured, which increases construction costs.

とにある。The purpose of this issue is to solve the problem of the main drainage pipe becoming full due to inflow water from many water collection branch pipes. An object of the present invention is to provide a drainage pipe that can reduce subsidence of the main drainage pipe due to water.

This configuration is characterized in that the parallel main pipes are connected to each other on opposite sides.

でき、各排水主管路が満水状態になるのを軽減できる。In the present invention, as shown in the above embodiment, the water collection branch pipe is connected only to one side of each main pipe, and - the conventional example in which the water collection branch pipe is connected to both sides of the main pipe Compared to -
Since the number of water collection branch pipes connected to the main pipe can be halved, the amount of inflow from the water collection branch pipes into one main drainage pipe can be halved, reducing the possibility that each main drainage pipe becomes full of water. .
勿瞼、排水路全体としての集水用枝管の本数は異なると
ころがないので、集水量については同等である。Since there is no difference in the number of water collection branch pipes for the entire drainage channel, the amount of water collected is the same.

排除できる。In addition, since the parallel drainage main pipes are connected to each other and the amount of water flowing through each main pipe is equal, the amount of water in each main pipe is
Both vehicles are equal, and the main pipes are distributed at intervals, so the above amount of water acts as an evenly distributed load on the burial site, and even on the downstream side where the load is large. It can effectively prevent sinking of drainage pipes and eliminate water leakage accidents.

υ[Since the aquatic pipeline is composed of multiple parallel main pipelines, and the water collection branch pipes are connected only to one side of the left and right main pipelines, the water collection branches connected to the - main pipelines are The number of pipes can be halved compared to the conventional example in which branch pipes for water collection are connected to both sides of a single main drainage pipe, and the amount of inflow water that enters one main pipe through the branch pipes for water collection can be reduced by half. This can be reduced by half, reducing the risk of drainage earthen pipes becoming full of water. In addition, pipes of the same size are used and multiple pipes are arranged horizontally to form the main drainage pipe, so pipe design is easy.In addition, the connection method using backing at the joints makes construction easy. Engineering IT costs become cheaper. Historically, by equalizing the amount of drainage water flowing down the parallel main pipes and distributing the water load, it is possible to prevent the drainage pipes from sinking and reduce water leakage accidents.
