The present invention relates to a water collecting well structure, and more specifically, the bottom concrete layer is configured to press down the water collecting well structure from above the water collecting portion for accommodating the groundwater, thereby pressing the bottom concrete layer of the existing concrete structure. It is about the installation process to secure and support the buoyancy and bearing capacity, such as the sump.

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, greater effort and costs are required than for conventional reinforced concrete structures to ensure the stability of the structure from water.

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 shape of the sump has many difficulties in achieving the purpose and construction of the functional purpose, the part where the sump is installed should be the deepest position, because the groundwater is collected a lot to perform the reinforced concrete work Becomes very difficult. 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. BRIEF DESCRIPTION OF THE DRAWINGS It is a figure which shows the mounting cross section of the conventional metal collection well. Referring to FIG. 1, such a metal water collecting well has a cylindrical structure, which breaks through the gulting finish surface 1 and has a form of a structure buried therein.

Conventional metal sump 110 is buried in the underground gulto finish surface (1) in the form of a tank, the upper portion of the concrete by the discarded concrete layer (2), the bottom concrete layer (3) and the pressed concrete layer (not shown) Supported. The outer side is fixed and supported while buried in the bottom concrete layer 3 through a protruding flange (not shown).

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 only a flange (not shown) needs to be fixed in position, even if the concrete layer is slightly broken or spaced apart, the position may be changed or damaged around due to a sudden weakening of the bearing force. Thus, using the bottom concrete layer itself, there is a need for a structure and a construction method in which the sump is pressed downward and pressed.

An object of the present invention is to provide a water collecting structure that can secure the bearing capacity while being pressed downward by the bottom concrete layer.

In another aspect, the present invention does not need to be manufactured according to the thickness of the floor concrete, it is an object of the present invention to provide a water collecting structure that can be used in accordance with the thickness and conditions of all the floor concrete only by replacing a part of the mold.

An object of the present invention is to provide a water collecting structure having a plate-shaped water collecting support, so that when the bottom concrete layer is thick, water collecting wells can be formed only by a water collecting portion having a simple plate shape.

Referring to FIG. 2, the collecting part 10 is formed with a reinforcing member 12 on the outside, and the reinforcing member 12 is placed under the bottom concrete layer 3, so that the bottom concrete layer 3 is a reinforcing member. Press (12) and it will function to support downward strongly.

The water collecting part 10 may be formed of iron, metal, or other various rigid materials, and the shape of the water collecting part 10 may include various shapes such as the bottom and the sidewall, and may have various shapes as long as the water can be accommodated therein, such as a cylindrical or square pillar shape. Can be. The water collecting unit 10 may be previously determined, manufactured and installed in shape or size according to the inflow of groundwater, rainwater, and sewage, and may be configured so that a separate mold (not shown) is detachable at the top thereof. Therefore, it is also possible to construct a buried mold that does not require removal. Since the mold (not shown) can also be manufactured on-site, it is possible to effectively cope with the formation of various floor concrete layers.

The reinforcing member 12 is a plate-shaped member which protrudes horizontally to the outside of the side wall of the water collecting unit 10. When the reinforcing member 12 is formed throughout the outer periphery along the side wall of the water collecting unit 10, it serves to reinforce the strength of the side wall itself. Alternatively, it may be possible to form only a part of the outer perimeter. The reinforcing member 12 is integrally coupled with the water collecting unit 10 and is placed below the bottom concrete layer 3. The bottom concrete layer 3 allows the reinforcing member 12 to be placed on the lower side or the lower side of the bottom concrete layer 3 so as to prevent the water collecting part 10 from rising by pressing the reinforcing member 12 with the weight of the entire bottom concrete layer 3.

In the bottom concrete layer 3, the reinforcing bar 40 is arranged in several layers. This is for reinforcing the strength of the bottom concrete layer 3, preferably, the reinforcing bar 40 is formed to extend directly above the position where the reinforcing member 12 is disposed, and the bottom concrete on which the reinforcing bar 40 is located. Preferably, the layer 3 is pressed against the reinforcing member 12.

For the installation of each configuration as described above, first excavate the space for the collecting portion 10 is seated in the gulto finish surface (1), and cast the discarded concrete 2 to a certain thickness. When the water collecting part 10 is seated in the scavenged space, the reinforcing member 12 is placed directly above the discarded concrete layer 2 and below or below the position where the bottom concrete layer 3 is to be formed. After arranging the reinforcing bar 40, the bottom concrete 3 is poured, and the pressing concrete 4 is poured while covering the lid 5 on the upper side thereof.

Referring to FIG. 4, as in FIG. 3, the coupling member 14 is formed above the reinforcing member 12, and the mold 20 is formed at an upper end thereof.

The mold 20 is disposed on the top of the water collecting part 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, so that the height of the mold 20 is changed. do. The mold 20 can be freely applied regardless of whether it is detachable later or integrated into a buried material, as long as it can form an outer surface of a bottom concrete layer such as a wood plate, an iron plate, and a metal mesh. Preventing inflow of groundwater from the outside into spaces where water or concrete mortar may leak, such as space between the mold 20 and the collecting portion 10, other open spaces or leaking spaces, and a portion of the outer circumferential surface of the collecting portion 10 It is advisable to install a regular index material in a certain thickness for waterproofing and sealing.

At this time, by changing the height and size of the mold 20 according to the thickness of the bottom concrete layer and the inflow of groundwater, rainwater, sewage, and changing the capacity of the pump (not shown), the water collecting unit 10 The size and shape of can always be used the same. Therefore, the collection part 10 can be standardized and compatible.
