Description

Reinforcement device for drainage pipes {omitted}

The present invention relates to a drainage pipe connection device for efficiently and firmly connecting each of the drainage pipes in the drainage pipe for underground drainage pipes.

In general, concrete fume pipes or synthetic resin spiral pipes are mainly used for drainage pipes, which are sold to the ground during the construction of agricultural and water supply, drainage, and wastewater pipes.

In this design, when the drainage pipe is buried underground and used for a long period of time, the load of external soil receives a lot of the upper part of the drainage pipe and both parts are the parts that firmly support the bending stress according to the earth pressure load of the upper part. The area where the compaction process is required when the soil is back into the soil of the soil

Therefore, the concrete fume pipe used for the corresponding solution is firm and has high external pressure strength, but there is a problem in the strength of the joints, and the synthetic resin spiral pipe is a flexible pipe with low external pressure strength, especially when it is buried under the ground and receives a concentrated load. To solve this problem, the middle part of the pipe is damaged and becomes impossible to serve as a drainage pipe. As shown in FIG. 3, the drainage pipe is installed along the drainage pipe line, but a careful necessity such as placing a reinforcing part in the lower and lower parts is required. Spiral tubes made of synthetic resins have the disadvantage of shortening the range of use, and there is a problem that synthetic spiral tubes rise up on mortars due to specific gravity difference during cement mortar input work, and the surrounding soil is not suitable for long-term use in soft ground. Drained due to ground subsidence due to leakage of connection site A leak in the water pipe caused a leak.

For the construction of drainage pipes and drainage pipes, they usually pass through slopes or soil reclamation areas or soft grounds to improve the efficiency of the land. In many cases, the construction work is carried out by filling the surrounding soil. In this case, the connection part of the drainage pipe is twisted due to settlement of the soft ground or leakage of the connection part. In this case, due to the concentrated load, the spiral pipe is broken or the cross-section is distorted in an elliptical shape. Therefore, for solving this problem, the upper part is concentrated and the cement mortar is configured to be suitable for the external pressure reinforcement of the drainage pipe on both sides. Drainage pipe to improve workability during the input job The present invention provides a reinforcement device that provides support for external pressure reinforcement of a furnace.
