The present invention relates to a water collecting well structure, and more particularly, is not limited to the height of the bottom concrete layer by a structure configured so that a form for forming the bottom concrete layer is disposed above the water collecting portion for accommodating groundwater. It is about the structure and its installation process to secure and support the buoyancy and bearing strength, such as the sump of the existing concrete structure by the concrete layer.

Sump is to treat the groundwater or rainwater below the basement of the building, and almost all of the buildings that are being constructed recently are installed. Such a water collecting well is used to collect and collect rainwater and groundwater at the construction site when the construction is in progress, and after the construction is completed, it functions to accommodate the collected water until the pump is discharged.

Since the sump should be lower than the bottom slab of the building, the installation of the sump requires reinforcement concrete work to separate the trench and form the sump structure, which requires separate air. In addition, to secure the stability of the structure from water, it takes more effort and cost than that of ordinary reinforced concrete structures.

Conventional water wells should meet the structural purpose of satisfying the bearing capacity as part of the floor surface and the functional purpose of water well to collect groundwater or rainwater and discharge them to the outside. It is formed of a reinforced concrete structure of the same thickness.

This type of water collection well has many difficulties in achieving the functional purpose and construction. Since the water well is installed at the deepest part, the groundwater collects in this area, so the reinforced concrete is in this area. The task becomes very difficult to accomplish. Therefore, there is a problem that not only takes excessive time, but also poor construction quality. In addition, other complex configurations to be connected to the sump is difficult to install in the thick reinforced concrete structure, its performance is degraded, post-correction problems are difficult.

In order to solve this problem, the integrated sump of metal was devised.

The outer side is fixed and supported while buried in the bottom concrete layer 3 through the protruding flange 112, and the rib 114 is provided therein to be used to reinforce rigidity.

Since the integrated metal sump 110 is formed integrally, there is an advantage that a large amount of concrete is used as in the prior art, or precise digging and designing are not necessary. However, the conventional metal sump 110 is inconvenient to vary the height of each sump in order to match the thickness of the bottom concrete layer (3) varying. In addition, since the position of the flange 112 must be fixed only, even if the concrete layer is slightly broken or spaced apart, there is a disadvantage in that the position is changed or the surroundings are broken due to a sudden weakening of the supporting force.

Referring to FIG. 2, the water collecting well structure of the present invention is largely composed of a water collecting well 10 and a mold 20, and has various functions and effects depending on the shape of the water collecting well 10 or the position of the mold 20. do. The collecting well 10 may be determined, manufactured and installed in advance in shape or size according to the inflow of groundwater, rainwater, and sewage, and a separate mold 20 may be detachably mounted on the top thereof, and may be removed in some cases. It is also possible to configure a buried mold that does not require. Since the mold 20 can also be manufactured on-site, it can effectively cope with the formation of various concrete floor layers. Sump 10 is a variety of cylindrical or square, octagonal pillar shape and the like, the upper portion is open collecting portion 12, the reinforcing member 16 is vertically arranged at regular intervals on the outer surface of the collecting portion 12, reinforcement One or more coupling holes 18 are formed on the surface of the member 16, and the flange 14 is formed on the upper end of the collecting portion 12 in the horizontal direction. The coupling hole 18 may be formed in a hole shape or a groove shape, and in the case of a groove shape, the coupling hole 18 may be configured in various shapes such as a straight line and an L shape.

The mold 20 is disposed on the top of the water collecting part 12 of the water collecting well 10, and the thickness of the bottom concrete layer 3 varies from 30 cm to 3.5 m depending on the buoyancy and the weight of the building. ) Height will change. If the mold 20 can form the outer surface of the bottom concrete layer, such as a wooden plate, iron plate, metal mesh, it can be freely applied regardless of whether it is separable later or embedded in a buried body. Preventing inflow of groundwater from the outside into spaces where water or concrete mortar may leak, such as spaces between the mold 20 and the sump 10, other open spaces or leaks, and parts of the outer periphery of the sump 10 It is advisable to install a regular index material in a certain thickness for waterproofing and sealing.
