Description

Reservoir tank and its construction method

The present invention relates to a storage tank and a construction method thereof, and more particularly, to a storage tank and a construction method thereof, which enables to stably maintain a structure despite the vibration or cracking of the ground and to stably maintain the ground during construction.

With the increase of buildings and the increase of land surface pavement rate, rainwater does not flood into the basement during heavy rains, but it frequently occurs during the rainy season during the rainy season.

This is because, due to the recent urban development, various structures such as buildings, asphalt, concrete pavement, parking lot facilities, etc. are rapidly increased, and the rainwater is directly discharged to the river through rainwater pipes, and a large amount of rainwater is concentrated at once.

Thus, if the rainy season exceeds the allowable inflow of rainwater, flooding leads to flooding of roads or houses and buildings by rainwater. On the contrary, when the inflow of rainwater decreases, the water quality of the stream deteriorates. In addition, there is a problem that the ground water is also depleted, and a storage tank has been developed that can adjust the outflow to the river by temporarily storing the rainwater in the basement.

The storage tank is usually buried underground, and in the case of soft ground, as shown in Figures 1 and 2, the ground 200 is excavated and the ground by constructing a nail (5) or earth anchor on the excavation surface After the protection of the cracks of the plurality of pillars (6) at a certain interval after the stabilization of the pillars by connecting the support beams (7) between the pillars, the earth wall (8) between the pillars to install the construction space of the storage tank After securing, the storage tank is assembled or manufactured in-situ.

As the construction of the storage tank is disclosed in Korean Patent Registration No. 10-0994805 (FIG. 3), a technique for assembling and manufacturing the factory-produced members in the field is disclosed.

However, in the prior art as described above, the outer members 100-1 constituting the side wall of the storage tank are manufactured and assembled at the design height of the storage tank, and in this case, because they interfere with the support 7 as shown in FIG. There is a problem in that the construction of the outer member (100-1) is difficult.

In addition, considering the fact that the height of the outer member 100-1 can be manufactured in the factory at a maximum of 7.5 m, it is difficult to manufacture and transport the outer member when the storage tank is installed at a depth of 12 to 15 m from the ground.

In addition, when the reservoir is buried to increase the thickness of the top member to secure the holding force of the top member 600 due to earth pressure, there is inconvenience in transportation, etc., and leakage occurs due to gaps between the top members 600. There is a problem.
