Description

Foundation construction of upper water supply pipe for subsidence prevention The present invention relates to a water pipe installation structure for preventing subsidence, and more specifically, to a water pipe installation structure for preventing subsidence that prevents a water pipe installed underground from subsiding or deforming due to changes in the external environment and enables stable use. A water supply pipe generally refers to a pipe used to supply and distribute tap water. These water pipes are installed to supply water from a source to places requiring a constant water supply, such as residential facilities or factories, and are typically installed by being buried underground to avoid affecting various buildings or infrastructure installed above ground. In this process, a specific location underground is excavated to allow for the insertion of the water pipe, and a pipe made of a sturdy material is inserted. Concrete or asphalt is then applied to the top of the pipe to prevent it from being exposed to the outside, thereby preventing various impacts from the surface from being transmitted to the pipe and causing damage. In addition, as explained above, water pipes are generally made of high-strength metal materials to withstand the continuous water pressure of the water source, and sealing work is performed at the connection points of the water pipes to prevent the water being transported through the pipes from being exposed to the outside and to prevent contaminants from penetrating into the inside of the pipes. However, due to their installation location being buried underground, these water pipes had a problem where corrosion could occur from rainwater falling to the surface, and if subsidence occurred in the ground where the pipes were installed due to rainwater or other factors, the installation location of the water pipes could be changed. This meant that, as the water pipes were formed in a circular tubular shape, there was no means to support the pipes' position in the event of subsidence caused by rainwater or other factors in the ground where they were installed. Consequently, the subsidence could accelerate due to the weight of the pipes, and this could lead to the pipes being damaged as their installation location was altered. Accordingly, a water pipe installation structure capable of maintaining a stable position for water pipes installed underground has recently been proposed, as described in literature (1). However, conventional water pipe installation structures such as those described in document (1) can maintain the position of water pipes installed underground and enable their use, but when subsidence occurs underground, it is difficult to easily prevent the water pipe from sinking due to the load, and it is difficult to easily prevent the water pipe buried underground from being exposed to external impact.

FIG. 2 is another cross-sectional view illustrating the combined state of the water pipe installation structure for preventing subsidence according to the present invention. FIG. 3 is another cross-sectional view illustrating the combined state of the water pipe installation structure for preventing subsidence according to the present invention.
