Description

Portion Anti-settlement Apparatus for use of drain pipe of softground The present invention relates to a device for preventing pipe subsidence in soft ground, and more specifically, to prevent pipe subsidence by installing an intrusion prevention structure in soft ground, such as riverbanks, or in sections where a large amount of leachate is generated. Generally, vertical displacement of a structure or part of a structure caused by the compression of the ground is called settlement, and if the settlement of all parts of a structure is the same, it is called uniform settlement. When uniform settlement occurs, cracks do not form in the structure, and only the vertical position changes. On the other hand, when differential settlement occurs, where the magnitude of settlement varies depending on the position of the structure, cracks or tilting occur in the structure, adversely affecting the function and safety of the structure. Ground settlement occurs when the ground is compressed due to causes such as increased subsurface stress from structural loads (elastoplastic deformation of the ground), increased self-weight of the ground due to a drop in the groundwater level, drying shrinkage of clayey soil, weakening of ground bearing capacity due to increased water content, failure of foundations, collapse of underground spaces such as underground cavities or buried pipes, and softening after frost heave. Typically, sewer pipes are manufactured using a centrifugal forming method that utilizes centrifugal force. Reinforcement bars are assembled within a formwork made of steel pipes, and concrete is injected into the formwork while the formwork is rotated at a constant speed to form a reinforced concrete structure. As shown in FIG. 1, a conventional sewer pipe is typically configured such that the sewer pipe (10) comprises a pipe section (11) and a socket section (14) formed integrally at one end (12) of the pipe section (11) into which the other end (13) of the pipe section (11) is inserted, and is buried underground in a state where the other end (13) of the sewer pipe located upstream is inserted into the socket section (14) of the sewer pipe installed downstream. In this case, if the ground where the sewer pipe (10) is buried is soft ground, the sewer pipe (10) subsides over time, causing leakage to occur due to the separation or damage of the connection of the sewer pipe (10), and this leakage further weakens the soft ground, causing the subsidence of the sewer pipe (10) to become more severe. Accordingly, Korean Patent No. 10-598769 (registered July 3, 2006) discloses a "structure for preventing subsidence of sewer pipes on soft ground" (hereinafter referred to as "Prior Art 1"), which prevents subsidence and collapse of sewer pipes by installing a subsidence prevention structure at the bottom of a sewer pipe installed on soft ground, and Korean Patent No. 10-0619403 (registered August 25, 2006) discloses a "structure for installing a triangular sewer pipe for safety to prevent subsidence on soft ground" (hereinafter referred to as "Prior Art 2"), which prevents subsidence on soft ground by forming a triangular shape on the upper side so that the load received by the soil is reduced when the sewer pipe is buried in the ground by forming a flat lower surface to have a large contact area with the ground. However, prior art 1 has a problem in that it cannot prevent the subsidence and collapse of sewer pipes because the subsidence prevention structure itself subsides when installed on soft ground, and prior art 2 has a problem in that even if the contact area of the lower surface is formed wide, the effect of preventing subsidence is insufficient when constructed on soft ground. Therefore, there is a need to develop technology that can effectively prevent the subsidence of sewer pipes when installing them on soft ground.
