Description

Modular intermediate collection box for draining groundwater above the appropriate level {INTERMEDIATE WATER COLLECTION BOX MODULE FOR DRAINING UNDERGROUND WATER EXCEEDING AN APPROPRIATE LEVEL}

The present invention relates to a structure for draining the groundwater at the bottom of the lower foundation of the building. More specifically, the groundwater level (TOTAL HEAD) at the bottom of the lower foundation of the building is the design stability level, that is, the self-weight of the building and the surrounding area. In order to maintain the groundwater level below the theoretical groundwater stability level reflecting the safety factor, the groundwater penetrating into the base of the lower part of the building is collected in the middle of the groundwater level until the design stability level. In addition, the present invention relates to a modular intermediate collection box configured to discharge and drain into a conventional drainage system when the design level is exceeded.

In general, if there is too much groundwater around the building, the groundwater acts as a kind of buoyancy to the building, threatening the safety of the building. On the contrary, if the groundwater existing around the building is excessively removed by, for example, forced drainage, the space where the groundwater exists is vacant and the ground subsides and threatens the safety of the building.

The present applicant filed with the Korean Patent Office on May 6, 2000 under the name of "Drainage structure and construction method with active natural drainage structure to prevent buoyancy accident" and received the application number of patent application No. 10-2000-24169 One embodiment of the pending gun is shown in FIG. 1.

The illustrated drainage structure has a discharge pipe 14a installed adjacent to the groundwater stable water level indicated by a dashed-dotted line, that is, the design stable water level, and two collection wells 13 and 16. As used herein, the term "design stable water level" refers to the theoretical groundwater stability level that reflects the safety factor in the groundwater level where the self-weight of the building and the force of the working pressure of the groundwater around the building are balanced.

The drainage structure configured as described above collects the groundwater penetrating around the building through the perforated pipe 12 to the water collecting well 13, and when the groundwater level in the water collecting well 13 increases and approaches the design stable water level, the drain pipe 14a is opened. It is structured to move through the auxiliary sump (16). When the groundwater collected in the auxiliary sump 16 is over a certain amount, the pump is operated to be forcibly discharged to the outside. In this way, the drainage continues to maintain the TOTAL HEAD at the bottom of the lower foundation of the building below the design stability level.

The illustrated drainage structure ensures that the ground level (TOTAL HEAD) at the base of the building's bottom does not always exceed the design stability level, thereby avoiding buoyancy acted by groundwater threatening the safety of the building, while the groundwater is excessive. It is possible to drastically reduce the cost of removing and maintaining the building's anxiety caused by forced drainage.

However, the drainage structure according to the prior art shown has to install a separate building structure, such as the intermediate wall 11 to form two water wells, so the construction cost increases, and a wider for two water wells inside the building It needs space. In addition, in order to apply the drainage method using such a drainage structure to an existing building, it is necessary to change the structure or form of the building, so that its application is quite difficult and costs are increased.

In order to solve the problems of the drainage system according to the prior art described above, the present invention is to provide a drainage structure for draining the groundwater above the proper level, that is, the design stability level, while being able to simply install at low cost It is done.

Another object of the present invention is to provide a modular drainage structure that can be easily applied to existing buildings.

The purpose of the present invention is to secure the structure and extending upwards, the inner space of the case is divided into a drainage area and a catchment area, the space separating means having a height corresponding to the design stability level of the groundwater around the building And an inlet connected to the groundwater inflow passage from the outside of the building, a bottom plate closing the lower portion of the catchment region, and formed in the drainage region and connected to a catchment well for collecting the groundwater. This is accomplished by providing a modular intermediate catchment box containing an outlet.

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

2a to 5 show a preferred embodiment of the modular intermediate water collecting box 20 according to the present invention.

Referring to FIG. 2A, the modular intermediate collection box 20 includes a case 21, a separation wall 22, a bottom plate 24, an inlet 25, and an outlet 29.

As can be seen in Figure 2b, the back plate 21a is coupled to the case 21 by a fixing bolt 21b or the like to form a substantially rectangular cross-section, has an elongated shape up and down, and has a constant space therein. It will be appreciated by those skilled in the art that the cross section is rectangular in preferred embodiments, but any shape, such as other closed polygons or circular or elliptical, is possible.

The rear plate 21a is fixed to the building by means of the fastener 28 on the wall of the building, preferably the wall of the perforated pipe 50 for guiding the groundwater penetrating from the outside of the building to the water collecting well 40 or the like. do. The fastener 28 is formed in a shape protruding from the back plate 21a, integrally formed on the back plate 21a and extending therefrom, or may be formed by attaching a separate member to the back plate 21a. The free end is preferably pressed into the wall of the building.

The dividing wall 22 extends substantially up and down inside the case 21 described above, and the upper end thereof has a height corresponding to the design stability level of the groundwater around the building. Here, the design stability level means the theoretical groundwater stability level that reflects the safety factor in the groundwater level where the self-weight of the building and the force by the action pressure of the groundwater around the building are balanced. In addition, the height corresponding to the design stability level means that the groundwater level is high enough to not cause the instability of the building and excessive infiltration due to ground subsidence.

As described above, the partition wall 22 positioned inside the case 21 divides the space formed by the case 21 and the back plate 21a into the collecting region 34 and the drain region 32. In a preferred embodiment, the dividing wall 22 is tubular so that the inside of the tube is a catchment area and the outside is a drainage area.

On the other hand, the hot coil 35 around the dividing wall 22 in order to prevent the groundwater received inside the catchment area 34 freezes due to a drop in air temperature and freezes the partition wall 22 or closes the catchment area 34. Is placed. The hot coil 35 is preferably electrically connected to a power source (not shown) supplied to the building to generate heat when the surrounding temperature is below a predetermined temperature.

The bottom plate 24 is a member that seals and closes the lower end of the collecting region 34 of the separating wall 22, and is integrally formed at the lower end of the collecting region 34 of the separating wall 22 or a separate member is formed. It may be formed by being fixed to the lower end of the collecting region 34 of the dividing wall 22 to be sealed.

As described above, the inflow port 25 is formed in the water collecting area 34 whose lower end is sealed by the bottom plate 24. One end of the perforated tube 50 is coupled to the inlet 25. Therefore, groundwater flowing through the perforated pipe 50 from the periphery of the building may be collected in the catchment area 34. As can be seen in FIG. 3, in this embodiment, a flange 25b is formed at the end of the horizontal separation wall 22a extending horizontally from the tubular separation wall 22. As can be seen in FIG. 5, the flange 25c is formed in the flange 25c, and has an inner diameter that is approximately the same as that of the oil hole tube 50. As can be seen in Figure 3, the flange (25b) is arranged so that the inlet 25 is in communication with the perforated pipe 50 is fixed to the building 30 by a fixing bolt (25b).

On the other hand, the lower end of the case 21 of the drainage region 32 is opened to form the water outlet 29. It is preferable that the water collecting well 40 is formed below the water outlet 29 so that the groundwater discharged downward through the water outlet 29 can be collected in the water collecting well 40 without a separate pipeline facility.

As shown in more detail in FIG. 2A, the bottom plate 24 is provided with a box drain 26. The box drain 26 is in communication with the catchment area 34, in the middle of which a drain valve 27 is formed to intercept the fluid flowing through the box drain 26. Such a box drain 26 may be conveniently used for cleaning the inside of the modular middle water collecting box 20 of the present invention when removing foreign matter.

On the other hand, as can be seen in Figures 2a and 2b, the partition wall 22 is fixed to the back plate 21a by the partition wall support 37. One end of the partition wall support 37 is fixed to the inner surface of the back plate 21a by a known method, and the other end is divided into two parts in a form surrounding the partition wall 22 so that the partition wall 22 is accommodated therein. The fixing bolts 37a are coupled to each other.

In order to allow the modular intermediate collection box 20 configured as described above to be more firmly supported by the building 30, the separating wall 22 is formed by the pair of U-shaped supports 36. Is fixed to. As can be seen in Figure 4, the U-shaped support 36 formed in a substantially U-shape is formed with a screw hole 36a, the radius of the curved section is approximately the same size as the radius of the separation wall 22 It is. As can be seen in FIG. 3, the U-shaped support 36 is fixed to the building 30 using a fixing bolt 36b in a form surrounding the dividing wall 22.

Hereinafter, the groundwater drainage process by the modular intermediate collection box 20 according to the present invention having such a structure will be described with reference to FIG. 2A.

If the groundwater in the periphery of the building, in particular the bottom of the lower foundation, penetrates through the perforated pipe 50, the groundwater is first accumulated in the catchment area 34 via an inlet 25 formed in the case 21 of the catchment area 34. . At this time, the box drain 26 is closed by the drain valve 27, so that if the groundwater continuously penetrates, the water surface in the catchment area 34 is raised.

At this time, if there is a lot of groundwater around the building to form a water level higher than the design stable water level, the water level in the catchment area 34 is gradually increased so that the top of the dividing wall 22 of the height corresponding to the design stable water level. To the drain region 32. In this way, the groundwater discharge into the drainage area 32 keeps the groundwater level (TOTAL HEAD) of the bottom of the building foundation at the design stable level at all times to keep the building safe. Groundwater flowing over the dividing wall 22 to the drainage area 32 is collected in the sump 40 through the water outlet 29. That is, while the ground water level (TOTAL HEAD) of the base of the lower floor of the building is maintained at the design stable water level, the ground water continuously flowing into the sump 40 is collected. Water accumulated in the sump 40 is removed from the sump 40 by a drainage pump (not shown) by a certain amount or by any drainage method.

Thus, for example, when there is a large amount of groundwater to threaten the safety of the building in the vicinity, such as flooding, when using the modular intermediate collection box 20 according to the present invention, Regardless of the bottom foundation, the TOTAL HEAD can maintain the design stability level at all times to promote the safety of the building, and the TOTAL HEAD decreases relatively compared to the forced drainage. The amount of infiltration into the bottom is reduced.

However, if the amount of groundwater around the building is not large enough to form the surface below the design stability level, the surface of the groundwater that accumulates in the catchment area 34 does not reach the upper end of the dividing wall 22. Will form. In this case, the drainage pump (not shown) of the sump 40 does not need to be operated, and there is no fear of accidents caused by buoyancy of the groundwater, and the groundwater may be forcibly drained to reduce the risk of ground subsidence. have.

Meanwhile, the case 21, the separation wall 22, the bottom plate 24, and the box drain hole 26, which are members that come into contact with water in the modular intermediate collection box 20 according to the present invention, are made of stainless steel. desirable.

6 to 8 show a modular intermediate water collecting box 20 'of a modified embodiment of the present invention.

In the description, the same reference numerals are used for the same parts as those employed in the preferred embodiment, and the description thereof is omitted.

Referring to FIG. 6, the case 21 ′ is integrally formed, and a partition wall 22 ′ dividing the case 21 ′ into the catchment area 34 and the drainage area 32 is provided inside the case 21 ′. Is installed. In a variant, the dividing wall 22 'has a plate shape, the upper end of which has a height corresponding to the design stability level.

An inlet 25 ′ is formed by passing through a portion of the case 21 ′ forming the collection region 34.

In addition, the fixture 28 ′ is formed on the rear of the case 21 ′ and fixed to the building 30, thereby fixing the entire modular intermediate collection box 20 ′ to the building 30.

On the other hand, the sump connection pipe 60 is buried in the foundation of the building or installed by other known methods to connect a plurality of sump to each other, when the pump installed in a single sump failure is accommodated in the sump It is to prevent the groundwater from overflowing over the sump by flowing the ground water that can not be flowed to another sump connected by the sump connecting pipe (60). It is preferable that such a sump connection pipe 60 be made of PVC material.

Since the modular middle water collecting box of the present invention has a modular structure and is easy to install, the active drainage system of the existing building can actively maintain the TOTAL HEAD below the design stability level. Easily converted into a drainage system.

That is, for example, when applied to existing buildings having a forced drainage system, one of the modular intermediate water collection boxes manufactured in various sizes and shapes, which is suitable for the conditions of the building, is connected to the flange of the perforated pipe of the building. Once secured to the upper building, it is very easy to change the forced drainage system into an active drainage system that takes into account the design stability level.

In this way, if the system is changed into an active drainage system in consideration of the design stability level, the amount of groundwater flowing into the sump is not at all or greatly reduced. There is no fear of ground subsidence or greatly reduced.

In addition, the box drain has the advantage of making it easier to maintain the collection box installed in this way.
