The present invention relates to a water pipe installation structure for preventing settlement, and more particularly, it is installed in the upper and lower periphery of the outer circumference of the water pipe to be buried in order to friction with the ground when the settlement or deformation of the area where the water pipe is installed. Due to this, it is possible to prevent the sedimentation or deformation of the water supply pipe, and at the same time, to bury the water supply pipe in a safe and solid state, and to protect the outside of the water supply pipe buried in the ground during the excavation work, thus preventing the water supply pipe from being damaged by the excavator. The present invention relates to a water pipe installation structure for preventing settlement.

In general, water supply pipes supplying water to factories, houses, and various facilities are facilities for supplying water source with water suitable for human drinking, and are buried underground to a certain depth from the ground to secure ground space and beautify the living environment. The buried work of such a water pipe is made by cutting the ground into a space sufficient to allow a structure in which a plurality of water pipes having a constant diameter and length are connected in a line is placed therein, and the water pipe structure is longitudinally connected thereto. After the sediment is settled sequentially, the landfill work is completed by burying the soil.

Looking at the conventional method of laying the water pipes, it is simply used to dig the ground, put the water pipes there and then cover the ground again, so the construction is easy to use widely, especially in the downtown area to compact the soil located in the periphery of the water pipes While increasing the density between the soil and soil, by applying concrete or asphalt on the ground where water pipes are buried, the risk of water pipe damage due to settlement and collapse of the ground is minimized.

On the other hand, the water pipe is typically made of a relatively strong metal material, that is, a steel pipe welded by folding a casting or a rolled steel plate in a circular shape, because the excellent pressure resistance to withstand the water pressure, and the connection portion of the adjacent water pipes, such as sealing Waterproofing prevents leakage of water and contaminants, but water pipes are made of metal that can easily be corroded by rainwater. As a result, maintenance work and replacement of water pipes were frequently generated.

In particular, since the structure is buried in the ground to prevent damage caused by exposure, if the rainwater, such as rainwater stagnates for a long time in a certain place in the basement or intensively erodes only a certain part, the foundation supporting the water supply pipe is collapsed or weakened. Part of the water supply pipe can be settled down, and due to the characteristics of the water supply pipe, which is cylindrical, the landfill is soft ground, which is caused to sink due to the weight of the water supply pipe due to the lack of supporting area. As warpage or bending occurs, breakage and cracks are generated in a part of the water pipe, and there are many problems such as leakage and contaminants introduced into the breakage and cracks.

In addition, when rainwater penetrates into the soft ground during the rainy season with a lot of precipitation, the conventional water pipe buried structure does not have a drainage facility, thereby further weakening the bearing capacity of the soft ground and further accelerating the settlement of the water pipe.

The present invention is to solve the problems as described above, the water supply pipe due to the frictional force with the ground when the sedimentation or deformation of the area where the water supply pipe is installed is sequentially installed in the upper and lower outer periphery of the buried water pipe. It can prevent the sinking or deformation, and at the same time, bury the water supply pipe in a safe and solid state, and protect the outside of the water supply pipe buried in the ground during the excavation work to prevent damage to the water supply pipe due to the excavator. The purpose is to provide a water pipe installation structure for preventing settlement.

In order to achieve the above object, the present invention wraps the outer circumference of the water supply pipe with a ring body separated up and down, both ends are fixedly coupled to the outer circumference of the water supply pipe by fastening bolts and nuts, the upper support side bolts to the upper side A fastening ring body fixed vertically and fixedly installed at a predetermined interval from the outer circumferential edge of the water supply pipe, and the support bolts are sequentially fixed to the upper and lower parts;

A center disc having a fastening hole into which the support bolt of the fastening ring body is inserted is formed at the center side, and the center disc is fastened and fixed by a lower support nut and an upper fastening nut on the support bolt. In the outer periphery, the front left and right fixing rods and the rear left and right fixing rods are protruded, respectively, to the outer lower side, and a plurality of fixing bolts are vertically erected upwards at regular intervals on the upper surfaces of the front left and right fixing bars and the rear left and right fixing bars. It is formed, and the front left and right fixed rods and the rear left and right fixed rods are four sides expansion fixture surrounding the outer periphery of the water pipe;

Both sides are bent downwardly with long plates, respectively, and are positioned on the upper surfaces of the front left and right fixed rods, the rear left and right fixed rods, the front and rear left fixed rods, and the front and rear right fixed rods of the four-way expansion fixture, respectively. Through holes into which the fixing bolts are inserted are formed according to the positions of the respective fixing bolts, and each of the fixing bolts is fastened and fixed by fixing nuts to prevent the flow, deformation, and settlement of the water pipe due to the frictional force of the ground. It is characterized by having.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
