Description

Connecting device for drainage pipes {omitted}

The present invention relates to a drainage pipe connecting device for efficiently and firmly connecting the respective drainage pipes in the drainage pipes used for supply and drainage by laying on the ground.

In general, concrete fume pipes which are buried in the ground and used for drainage pipes in construction works such as civil engineering works and residential land development are manufactured to a certain length for transportation or construction and are connected to each fume pipe at the construction site. According to the drawing of the connecting device is as follows.

As shown in Figure 3 to form a joint (9) on one side of the connection portion of the concrete fume pipe (7) to join the other side of the connection to be connected to the drainage pipe joining method to refill the surrounding soil In order to complete the construction, the reinforcement device is provided in the semi-circular form according to my own invention application (10-01-34207), but in the field construction, it is on the outer side in the curved state of the connection part of the fume pipe. This product is used in close contact with the joint surface, and requires careful attention, such as needing a separate fastening device for inventory of mortar casting workability.If the mortar is filled incorrectly, the surrounding soil is leaked due to settlement due to soft ground. Caused.

In order to connect the waterway pipe and the waterway pipe, the laying work of the civil engineering works and the drainage pipe using water resources is mainly required to pass through the slope or the ridge to increase the land utilization rate. In order to meet the slope of the soil, the surrounding soil is often filled and buried. At this time, the connection part of the drainage pipe is twisted due to settlement or collapse of the soft ground, which makes it difficult to function as a waterway. Since the connection part is often difficult to use as a part breakage, it is to be easily used for repairing the construction site of a rigid and partially broken drainage pipe.
