The present invention relates to a water and sewage pipe preventing damage caused by vertical loads, and more particularly, a multi-family house reinforced to prevent water and sewage pipes from being broken by vertical loads due to soft ground when buried water and sewage pipes of public housing. It relates to a water and sewage pipe preventing breakage due to vertical load.

Generally, concrete fume pipes or synthetic resin spiral pipes were mainly used for the construction of public and residential water pipes and water pipes.

However, soil that is dug to be buried under the ground often passes through the fill and soft ground, and also the gravel is mixed depending on the region, so if the work that is constantly made to smoothly drain the drain pipe of the drainage pipe In addition, the process of maintaining the drainage pipe as described above while digging to a certain depth from the ground is a problem reality under a bad condition of the construction site.

In addition, the buried drainage pipe is buried in the process of laying the soil to be dug back to the depth of the process, most of the process, because the soil reinforcement is low soil reinforcement, the process of compacting in the buried process This requires a separate equipment due to the conditions at the construction site, and to reinforce the external pressure of the drainage pipe, it is necessary to reinforce the compaction work on both side walls of the drainage pipe buried in the damming work.

In addition, the drainage pipe used by laying underground is manufactured to a certain length during manufacture and transportation, and is continuously connected at the construction site to bury it, and the drainage pipe is buried in the ground due to heavy rain, etc. If the connection part is twisted to each other, the problem of water leakage occurs, for this purpose reinforcement of buried soil was often required.

In the present invention, when the drainage pipe is buried under the ground for a long time, the load of external soil receives a lot of the upper part of the drainage pipe, and both sides are the parts that firmly support the bending stress according to the earth pressure load of the upper part. The compaction process is required when the soil is back into the soil, and the lower part has been required to prevent leakage at the connecting part.

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 in the ground and receives a concentrated load. The middle part of the pipe is broken and the problem that the role of the drain pipe becomes impossible.

In addition, water and sewage pipes buried in the soft ground or collapse frequently occur or warp due to external force.

In general, water pipes for supplying water to factories, houses, and various facilities, and sewer pipes for transporting used sewage to remote sewage treatment facilities are buried underground to secure ground space and to beautify living environment.

Buried water and sewage pipes, the ground is cut into a sufficient space for seating the structure that connects a plurality of water and sewage pipes having a constant diameter and length in a line, where the water and sewage pipe structure sequentially in the longitudinal direction This is done by burying in earth and sand after being seated. Looking at the conventional method of embedding simply because digging the ground and put the water and sewage pipe there and then cover the ground again, the construction is easy and widely used. In particular, in urban areas, water and sewage pipes are formed by digging soils located at the periphery of water and sewage pipes to increase the density between the soils and by including concrete or asphalt on the ground where water and sewage pipes are buried. The risk of breakage is minimized. Therefore, in laying the sewage pipes, the above-mentioned construction method alone was sufficient to achieve the purpose without additional reinforcement work, and there was no problem in the stability of the water pipes.

However, in the case of frequent ground collapse and partial settlement, such as river basins or mountainous areas with high rainfall, there is a limit to laying water and sewage pipes only by the above construction method. That is, in the above-described construction method, since the water supply and drainage pipes are long connected in one direction, the bearing capacity for the transverse pressure is extremely weak, and even a slight ground subsidence of the water supply and drainage pipe buried site may easily cause the breakage and gaps of the water supply and drainage pipe to be bent or twisted. In addition, leakage and inflow of foreign matter may occur through such gaps.

In order to solve this problem, the wires connected to the plurality of anchors fixed to the ground are firmly connected to the outer circumferential surface of the sewer pipe, which is buried underground, so that the sewer pipe can be supported to some extent without bending or twisting the sewer pipe even when partial ground subsidence. Was previously filed in Utility Model Registration No. 318224.

However, the pre-invented design has a limit to the strength it can sustain, so that the fundamental solution of the problem described above has not been achieved.

Therefore, there is a need for a structure in which water and sewage pipes installed on the ground of public housings are not damaged and stably supported despite the up and down pressure.

The present invention has been made in order to solve the problems as described above, by supporting the upper and lower sewer pipes with expanded polystyrene (EPS) so that the sewage pipe is stably supported even in the settlement of the ground so as not to damage the water and sewer pipes, Even if the water and sewage pipe breakage occurs, the water flows along the space portion of the concrete outer case to have the purpose to suppress the leakage to spread outside.

The present invention is formed in the shape of the U-shaped opening to achieve the above object, the connecting projection and the connecting groove is formed in each of the front and rear ends, the outer wall is a concrete outer case is formed with a plurality of moving grooves; It is fixed to the inner bottom of the concrete outer case, and the bottom shape is formed in the same shape as the bottom of the concrete outer case, the roughly hemispherical groove portion is formed on the upper surface, the central portion of the groove portion is protruded to form a seating protrusion, the seating protrusion Foamed polystyrene support that is gripped to both sides of the gripping portion of the guide is located; Comprising an arc-shaped gripping portion and a guide protrusion formed by protruding one side of the outer surface of the gripping portion, the guide projection is inserted into the moving groove; the guide is moved up and down; The upper part of the sewer pipe provides a water and sewage pipe to prevent damage due to the vertical load of the multi-family house, characterized in that the sand is laminated.
