The present invention relates to a structure for preventing damage to water and sewage pipes in a soft ground of a multi-family house, and more particularly, to a structure of a multi-family house reinforced to prevent damage to water and sewage pipes due to soft ground when buried water and sewage pipes of a public house. It relates to a water and sewage pipe preventing damage caused by 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 drain pipe as described above while digging to a certain depth from the ground while the dug drainage channel is a lot of reality under the bad conditions 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 in spite of up and down pressure as well as twisting in various directions.

The present invention has been made in order to solve the problems as described above, surrounding the upper and lower sewer pipes with expanded polystyrene (EPS), the upper and lower sewage pipes fixed a plurality of lower supports and the upper cover, connecting the lower support and the upper cover The purpose of the present invention is to provide a structure for preventing damage to the sewage pipes in the soft ground of the apartment house where the water and sewage pipes are stably supported to settle and torsion of the soft ground so that the water and sewer pipes do not break.
