The present invention relates to a basement floor drainage construction, and more specifically, to prevent excessive pressure on the drainage path while high water pressure is generated by improving the drainage structure that is constructed below the concrete floor of the basement floor. Drain structure.

In general, when a large amount of groundwater exists around and underneath the building, the building receives a buoyancy force due to the groundwater, which causes the building to rise and is destroyed, threatening safety. On the contrary, if the groundwater existing around and underneath the building is rapidly removed by forced drainage, the ground where the groundwater existed suddenly becomes empty and the ground sinks, which causes the building to fall and threaten its safety. .

For the up-water pressure treatment on the foundation floor of the building, it is equipped with a sump, drainage, and drainage pipe under the foundation floor, and when the groundwater flowing into the site is collected into the sump along the drainage, it is periodically pumped and discharged. It is a permanent drainage system to prevent positive pressure. This has the advantage of more stable and permanently solve the problem of up-water pressure in proportion to the high groundwater level compared to the conventional method.

This permanent drainage method uses groundwater as the primary infiltration into drainage materials arranged horizontally or vertically at a predetermined interval on the gulting finish surface of a large underground floor, and the drainage flows directly to the sump well through another drain pipe. . At this time, the groundwater collected in the drainage is pushed to the sump well under a certain pressure. If the area of the building is large, the length of the drainage and drainage pipe is increased, and the upstream pressure of the drainage and the drainage pipe is accumulated at the end of the drainage and drainage pipe. Too much pressure. In addition, during rainy weather and during flooding, the amount of groundwater is rapidly increased, and local drainage drains excessively upward water pressure. Therefore, there is a fairly high pressure in the drain, drain pipe.

Therefore, when the groundwater discharged through the drainage path increases rapidly and excessive upward water pressure is generated or when the upward water pressure accumulates and pressurizes over the long drainage road, a structure for preventing damage or deformation of the drainage path or the building is required. to be.

A conventional drainage structure will be described with reference to the drawings. Referring to Figure 1, when the basement floor drainage construction method, when the basement is constructed, concrete 10 is placed on the floor, and on one side, the sump 1 of a certain area is lower than the concrete floor, and the sump 1 ) Is constructed so that the outlet side (3a) of the drain pipe (3) embedded in the concrete layer (10) protrudes, and the groundwater collected in the sump (1) is pumped to the outside by a pump (not shown) Consists of.

Between the concrete layer 10 and the gulto finish surface (2) is constructed so that the concrete is poured in the state that the vinyl (not shown) and non-woven fabric (not shown) for the waterproofing treatment, the concrete layer 10 is poured A separate layer of gravel may be formed before it can. The concrete layer 10 includes discarded concrete that is first cast on the gulting finish surface 2, and bottom concrete and pressed concrete that are poured on the top.

Concrete wall and base wall in the basement floor to prevent cracking and leakage of the floor of the concrete layer 10 by draining the groundwater pressurized to the concrete layer 10 by the high water pressure caused by the water head difference occurring in the underground. When the bottom of the concrete layer 10 is poured to a certain thickness, the drain pipe 3 is embedded in the thickness of the concrete layer 10. At this time, the drain pipe 3 is disposed on the outer bottom surface of the concrete layer 10 is formed horizontally to be connected to the sump (1).

In this conventional structure, when the groundwater is generated by the upward hydraulic pressure to the bottom of the bottom of the concrete layer 10 through the gulting finish surface (2), the groundwater is discharged pipe (3) located on the outer bottom of the bottom of the concrete layer (10) At the same time as it flows into the sump (1). In such a horizontal drainage structure, if the upward hydraulic pressure increases more than usual, the internal space of the drainage pipe 3 is constant, so that the groundwater fills the drainage pipe 3 and the excessive pressure causes the drainage pipe 3 and the concrete around it. Extends to layer 10. This causes cracks or breakage in the concrete layer.

In order to solve the above problems, it is an object of the present invention to provide a drainage structure for alleviating and accommodating excessive upward water pressure in a construction site having a wide bottom surface and a long drainage.

The structure of the present invention for achieving the above object is, in the drainage structure for maintaining the proper water pressure of the groundwater generated from the bottom of the basement building structure, disposed horizontally or vertically on the gulto finish surface, groundwater A drainage passage flowing into the interior thereof; A vertical communication path connected upwardly with the drainage passage; And a horizontal communication path connected to at least one vertical communication path and positioned horizontally above a predetermined height than the drainage path.

The horizontal communication path is characterized in that the one end is connected to the sump formed on one side.

The horizontal communication path is characterized in that it is disposed before casting concrete. The horizontal communication path is characterized in that it is disposed after the discarded concrete pouring. The horizontal communication path is characterized in that it is disposed before the bottom concrete pouring. The horizontal communication path is characterized in that it is disposed after the floor concrete pouring.

The horizontal communication path is characterized in that it is disposed in the floor concrete. The horizontal communication path is characterized in that disposed in the discarded concrete.

Hereinafter, with reference to the embodiment of the present invention configuration shown in the accompanying drawings, it will be described in detail the configuration of the present invention.

2 is a cross-sectional view showing a first embodiment in which the drainage material of the present invention drainage structure is disposed on the gulting finish surface. Referring to FIG. 2, the drainage material 20 is horizontally disposed on the gulting finish surface 2, and a plurality of vertical communication paths 22 vertically formed on the drainage material 20 and the plurality of vertical communication paths 22. The horizontal communication path 30 is formed horizontally to be connected to the sump (1) by connecting to one passage is connected.

Drainage 20 is variously configured in the form of pipe, drain mat, S-shaped bundle tube, plate, plate-shaped bundle tube, hollow tube, hose, synthetic resin tube, perforated tube, non-pipe, drain plate, concrete block It can be made of various materials such as wood, resin, geotextile, and metal. Alternatively, when pouring the concrete layer 10 may be integrally constructed within the thickness of the concrete layer 10 by a formwork (not shown) to form a drainage path. Drainage 20 is directly connected to the sump (1). In general, the groundwater collected in the drainage 20 flows out into the sump 1 through the outlet 20a of the drainage 20.

In rainy weather and during flooding, the amount of groundwater rapidly increases and flows into the drain 20 with a high upward pressure. In this case, the groundwater pushed into the drain 20 is not only horizontally pushed out but also along the vertical communication path 22. It moves upward and is pushed out into the sump well 1 through the horizontal communication path 30. Therefore, the groundwater is discharged to another route through the vertical communication path 22 before excessive pressure is generated in the drain 20, thereby preventing an excessive increase in the upstream pressure.

3 is a cross-sectional view showing a structure modified from the first embodiment of the present invention drainage structure, Figure 5 is a perspective view thereof. 3 and 5, it can be seen that the water collecting well side end 20b of the drain 20 is blocked. Since the weight of the building is not high in the early stage of construction of the building, the upward hydraulic pressure is not large, and the groundwater is drained on the gulto finish surface (2) through the drainage (20). Hydraulic pressure is generated more than a certain amount. At this time, the water collecting well layer end 20b of the drain 20 may be blocked so that the groundwater is not discharged until a constant upward water pressure is generated. That is, it is possible to prevent the drainage of the groundwater before the water level of the groundwater flows along the vertical communication path 22 to the horizontal communication path 30 so that the upward water pressure increases. This is also a problem of excessive upward water pressure of groundwater, but if the groundwater is discharged excessively, it is also a problem that the building is seated while empty space is generated in the basement, so it is to discharge while maintaining a constant pressure and groundwater level to prevent this. .

The drain 20 and the horizontal communication path 30 of the first embodiment may be arranged in various shapes at various locations. Drain 20 may be located on the bottom of the discarded concrete on the gulting finish surface (2), or may be located in the discarded concrete or above the discarded concrete. In addition, the bottom concrete, the bottom of the pressed concrete, may be located in or inside. In addition, the horizontal communication path 30 is also sufficient to be located above the drainage material 20 by a predetermined height, there is no particular limitation on the position, the position is formed, as will be described below, to be installed in the trench or gravel layer It may be.

4 is a cross-sectional view showing a second embodiment of the present invention drainage structure. Referring to FIG. 5, the upper drainage path formed by the vertical communication path 22 and the horizontal communication path 30 is not formed at the water collecting well side end portion of the drainage material 20, but a structure formed in the middle of the drainage material 20. Indicates.

The groundwater accumulated in the basement of the building flows into the drainage due to the self-weight of the building and the upward water pressure due to the increase of the groundwater. The groundwater flowing to the drainage is pushed out in a certain direction by the upward hydraulic pressure. If the upward pressure of the groundwater continues to increase due to rainy weather or an increase in the quantity of rivers, the high pressure is applied to the drainage. In particular, when the area of the building is large, the drainage is also long. If the middle pressure is not lowered in a long drainage channel, high pressure is eventually accumulated, and excessive upward pressure affects the drainage.

Therefore, in order to lower the excessive upward water pressure in the middle, the upper groundwater receiving space may be formed for each basin not only in the sump side end but also in the middle of the drain. Accordingly, excessive water pressure is reduced while the groundwater is accommodated in the empty vertical communication passage 22 and the horizontal communication passage 30. Therefore, in such a structure, the water pressure flows to the water collecting well side or the drainage side by decompressing the watershed in advance according to the path of each basin, and since the water pressure flowing into each basin is controlled, a thick pipe or various dispersion paths are prepared for the inflow of high pressure groundwater. There is no need for a plurality of main drain pipe, and there is no need to directly connect the drainage in various areas to the sump, it is possible to accommodate the water pressure of the groundwater flowing into the minimum pipe.

The present invention smoothly accommodates excessive upward water pressure increase due to the increase of groundwater and mitigates the adverse effects, thereby preventing cracks and breakage of buildings.

In addition, it is not necessary to diversify the drainage path by mobilizing a large number of pipes in preparation for excessive upward water pressure increase, and it is possible to construct a drainage path system with only a few drainage pipes and pipes, thereby reducing costs and simplifying construction.

In addition, the water pressure can be adjusted beforehand for each basin, so that the water pressure treatment is quick and the configuration is simplified.
