Description

Groundwater Level Control Drainage System {System for drain regulation underground water}

The present invention relates to a groundwater level control drainage system, and more particularly, to a groundwater level control drainage system in which groundwater is easily collected and drained to a sump well only when the collected groundwater exceeds a set pressure. .

In general, excavation work is carried out to a predetermined depth for the construction of civil and architectural underground structures, and the foundation structure is formed on the ground (floor surface) where the excavation is completed, and based on the foundation structure, It will be constructed.

When the groundwater penetrates into the foundation structure, the groundwater acts as a positive pressure on the underground structure (building), and the positive pressure is caused by the difference in head structure due to the water head difference caused by the bottom of the underground structure (building) and the surrounding ground water level. It acts as a lifting force.

Therefore, as a countermeasure against the positive pressure caused by the groundwater in the construction of civil engineering and building structures with underground floors, the foundation thickness of the underground structure may be increased, or a rock anchor or the like may be installed to resist the positive pressure, or By installing a drain pipe, the groundwater is collected and drained to reduce the positive pressure.

Recently, a method of draining groundwater into a sump is installed by installing a drainage pipe on a foundation structure. For example, a groundwater drainage device of an underground structure under ground is disclosed in a main pipe of an existing patented method.

However, such a conventional drainage device is installed to collect the groundwater, that is, the main drain pipe, a plurality of sockets, drain boards, etc. are interconnected and installed to increase the workmanship due to many components, the workability will be reduced during installation In addition, the city park and construction costs were increased.

In addition, the conventional water collecting well is provided with a water level adjusting device for draining only when the water to be collected exceeds a set closing pressure, and the water level adjusting device has a body portion as disclosed in Korean Patent Publication No. 10-0913996. The sluice member installed on the inlet pipe side is elastically supported by the spring of the upper part to maintain the closing pressure of the drain pipe.

However, since the pressure of such a spring is difficult to adjust, the spring is operated at a pressure higher than the closing pressure and opened, even though the spring is operated at the closing pressure set during the water level adjustment and the drain pipe should be opened. There were disadvantages that followed many difficulties.

In addition, this spring has a fatal disadvantage that fatigue due to the repeated operation and the spring pressure drops eventually the closing pressure set during the level control is different from the initial set pressure.

Accordingly, the present invention has been made to solve the problems of the prior art as described above, by making only the drain board in the water drainage device can not only easily collect the groundwater to the water collecting well, but also improve the construction of the water drainage device The purpose is to provide a groundwater level control drainage system to reduce the city park.

(A), (b), (c) and (d) of FIG. 4 are diagrams showing a central channel of the main drain board of the water collecting and draining device according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, in the reference numerals to the components shown in each drawing of the present invention, it should be noted that the same reference numerals as much as possible even if shown on the other drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

1 to 4 is a view showing the groundwater level control drainage device and its configuration according to the present invention.

As shown in FIG. 1, the groundwater level control collection and drainage device of the present invention is composed of the foundation structure 10 formed on the foundation construction reference plane (final excavation surface) of the ground layer 1, Water collecting and draining device 100 configured through a fiber, water collecting wells 200 respectively configured at both sides of the water collecting and draining device 100, and water level control device 300 respectively configured in the water collecting well 200. ).

The collection and drainage device 100 shows only a part of the drain boards 110 and 120 and the collecting well 200 on one side, which will be described later in FIG. 2, but opposite sides thereof are configured to be symmetric with each other as shown in FIG. 1. Make sure you know.

As shown in FIG. 2, the collection and drainage device 100 is installed between both collection wells 200 and connects both collection wells 200 to the main drain board 110 and the main drain board 110. It includes a sub-drain board 120 installed perpendicular to the main drain board 110 on one side of the.

The main and sub drain boards 110 and 120 are formed of rectangular plates 111 and 121, and the plates 111 and 121 protrude downward from the plates 111 and 121. The protrusions 112 and 122 are spaced apart at equal intervals.

The protrusions 112 and 122 are formed by being pressed and pressed integrally from the plates 111 and 121, and an upper surface thereof is formed by the grooves 113 and 123 that are opened.

Accordingly, when the main and sub drain boards 110 and 120 are connected, the protrusions of the drain boards located at the upper part are inserted into and coupled to the grooves of the drain boards located at the lower part, that is, the connection parts between the drain boards 110 and 120 are connected. The volume between the overlapped (stacked) drain boards 110 and 120 is slimmed. In this case, the connection between the drain boards 110 and 120 is performed by inserting one side protrusion 112 of the main drain board 110 into one groove 123 of the sub drain board 120. As the main drain board 110 is positioned on the board 120, water leakage may be minimized when the groundwater is collected through the water passage 114 of the main drain board 110 to be described later.

In addition, the protrusions 112 and 122 are formed to be inclined to protrude so as to gradually decrease in diameter from the plates 111 and 121 to the lower ends thereof, thereby making the volume of the overlapped drain boards 110 and 120 more slim. Will be.

The protrusions 112 and 122 are easily damaged by a load or pressure acting on the panel.

And, if the diameter (D) (d) of the upper and lower ends of the protrusions 112 and 122 are less than 10 mm and 8 mm, respectively, the width of the protrusions 112 and 122 becomes smaller to form the protrusions 112 and 122. The amount of water flow in between is increased, but the protrusions 112 and 122 can be easily broken by pressure, and if the diameter (D) (d) exceeds 12 mm and 10 mm, respectively, the pressure is somewhat stable but the water flow rate is low. There are disadvantages to losing.

In addition, if the spacing l of the protrusions 112 and 122 is less than 15 mm, the water flow rate is drastically lowered due to the formation of the dense protrusions 112 and 122, and if it exceeds 20 mm, the water flow rate increases. However, there is a disadvantage that the protrusions 112 and 122 are easily vulnerable to load or pressure.

Therefore, the protrusions 112 and 122 are most preferably formed with a height h of 20 mm, an upper end diameter D of 12 mm, a lower end diameter d of 10 mm, and an interval l of 20 mm. desirable. That is, only the protrusions 112 and 122 are formed with such specifications, so that the most stable and smooth water flow rate can be maintained.
