Description

Drainage structure with upward hydraulic pressure control {Vertical type basement drainage system}

The present invention relates to a drainage structure that can be adjusted upward hydraulic pressure, more specifically, through the various drainage paths formed by the ground surface infiltrating the lower part of the building floor concrete, gravel, bundle tube, perforated pipe, geotextile, etc. In order to prevent the problem caused by excessive groundwater discharge when discharging to the sump installed on one side of the site, the construction is to raise drainage to balance the force caused by the pressure of the groundwater and the working pressure of groundwater on the floor of the building. It relates to a drainage structure capable of hydraulic pressure adjustment.

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 a large amount of 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. do.

Many methods are used through dead weight and permanent (buoyancy) anchors for the up-water pressure treatment on the foundation floor of the building, but this is limited in that the continuous reliability of the buoyancy anchor's tensile force is not guaranteed with respect to the durability and safety of the building. have. An improved method is to form an artificial catchment and drainage layer under the foundation floor so that the groundwater flowing into the site is collected in the catchment along the drainage path and pumped and discharged regularly so that the foundation floor concrete does not act as a positive pressure. Permanent drainage system method. 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.

Hereinafter, with reference to the accompanying drawings will be described in more detail the drainage structure capable of adjusting the hydraulic pressure in accordance with a preferred embodiment of the present invention.

Figure 2 is a view showing an embodiment of the drainage structure capable of adjusting the upward hydraulic pressure of the present invention.

Referring to Figure 2, according to a preferred embodiment of the present invention, the upstream hydraulic pressure adjustable drainage structure has a predetermined height upward from the drainage space 10 on the gulto finish surface (1), with the discarded concrete 20 It includes a pressure reducing pipe (60) for raising and lowering the drainage path to a position higher than the bottom concrete 40, and a protruding pipe (50) formed at the end of the drainage space (10).

The drainage space 10 is a passage for allowing the groundwater to flow, and may be configured in the form of formwork on the concrete layer or the gulting finish surface, and fills a separate gravel layer, a barrier layer, a sand layer, a drain board, a drain mat , Drain pipe, perforated pipe, bundle pipe, geotextile, etc. may be filled to form a drainage layer. The drainage layer is a portion that fills the drainage space 10 with various materials, and serves to smooth the collection and drainage.

The pressure reducing tube 60 is connected to the upper end of the drain space 10, the flow path is formed therein, so that the ground water flowing in the drain space 10 to drain to the sump 30, The upper extension pipe 62 which is formed so as to rise vertically upward from the end of the drainage space 10, the lower extension pipe 64 which is directed downward again, and the connection which connects these upper extension pipe 62 and the lower extension pipe 64 with each other. Including the tube 66, it is formed in the form of a whole 'U' shaped tube upside down.

The upper extension pipe 62 has a predetermined height to balance the weight of the building and the force due to the action pressure of the groundwater in the lower part of the building, the height is formed differentially according to the size of the sump and the working pressure of the groundwater.

The decompression tube 60 formed in this way is collected in the upper extension pipe 62 until the groundwater penetrating into the bottom surface of the building becomes the design stable water level, and in the case of exceeding the design stable water level, the connecting pipe 66 and the lower extension pipe 64 are formed. Drain through the sump (30).

As such, when the upstream water pressure of the groundwater flowing through the drainage space 10 is less than the water head difference of the height of the upper extension pipe 62 of the pressure pipe, the water is not drained, and if it exceeds the drain water, the water is discharged through the lower extension pipe 64. As a result, it is possible to prevent a large amount of groundwater to be discharged even in the small upward water pressure, thereby preventing the ground from sinking or weakening due to excessive groundwater drainage.

Protruding tube 50 is formed to protrude horizontally to the end of the drainage space 10, and includes a blocking member 52 to block the inside. In the initial stage of construction, since the upward pressure of the groundwater is weak, decompression is not necessary, so that the groundwater is discharged directly through the protruding pipe 50. And since the construction of the upward hydraulic pressure after the construction, the groundwater in the drainage space 10 passes through the decompression tube 60, in which case the groundwater does not close the protruding pipe 50 of the drainage space 10, Since it is discharged directly to the protruding pipe 50 without passing through 60, by closing the protruding pipe 50 by using a blocking member 52, such as a valve, the groundwater flowing into the protruding pipe 50, the pressure-reducing pipe 60 To be discharged accordingly.

On the other hand, in some cases, even after construction, the upward water pressure of the groundwater may be weak, so that decompression may not be necessary. In this case, the protrusion pipe 50 of the drainage space 10 is opened so that the groundwater is discharged directly to the protrusion pipe 50 without passing through the pressure reducing pipe 60.

Under special circumstances such as heavy rain and rainy seasons, the groundwater is concentrated excessively around and underneath the building. In this case, the groundwater penetrating into the bottom of the building is discharged more quickly than usual, and the water pressure on the floor of the building must be kept constant and adjusted. Therefore, when the groundwater is driven to the periphery and the lower part of the building above the reference value, by opening the protruding pipe 50 blocked by the blocking member 52, the ground water to the protruding pipe 50, without passing through the decompression pipe 60 It is to be discharged immediately, to discharge the groundwater faster than usual, and to maintain a constant, upward pressure on the floor of the building.

3 is a view showing another embodiment of the drainage structure capable of adjusting the upward hydraulic pressure of the present invention. Referring to FIG. 3, the drainage structure of which the upward hydraulic pressure control of the present invention is configured to further include a drain pipe 54 in FIG. 2.

The drain pipe 54 is connected to an end of the pressure reducing pipe 60 at an upper end of the drain space 10, and when the protrusion pipe 50 is formed at the end of the drain space 10, As the tube connected to the lower side of the end, it comprises a blocking member 56 to block the inside, like the protruding tube 50.

The drain pipe 54 formed as described above may be used to forcibly drain the suspended matter and sediment accumulated in the drainage space 10 toward the sump 30. In addition, when the groundwater is excessively concentrated around and under the building, similar to the protruding pipe 50, the ground water penetrating into the bottom surface of the building is quickly discharged by opening the drain pipe 54 blocked by the blocking member 56. As a result, it is possible to maintain and regulate the constant water pressure up to the floor of the building.

Figure 4 is a view showing another embodiment of the drainage structure capable of adjusting the upward hydraulic pressure of the present invention.

First, referring to FIG. 4A, the drainage structure capable of adjusting the upstream pressure of the present invention is configured to further include an auxiliary connecting pipe 67a in FIG. 2.

Auxiliary connecting pipe (67a) is a pipe that is formed to protrude along the longitudinal direction of the upper extension pipe (62), a plurality of cases may be formed, like the protruding pipe (50) blocking member 68 to block the inside thereof ).

This auxiliary connector (67a) is to ensure that when the groundwater is excessively concentrated around and under the building in a special situation, such as heavy rain, to quickly discharge groundwater penetrating into the bottom of the building than usual, as well as around and below the building The furnace is configured to discharge groundwater differentially depending on the amount of groundwater.

That is, the auxiliary connector 67a is normally configured to be closed by the blocking member 68. However, when the groundwater is concentrated around the lower part of the building and below the reference value, the auxiliary connecting pipe is blocked by the blocking member 68. Open (67a) to allow rapid discharge of groundwater that penetrates the bottom of the building.

At this time, the auxiliary connecting pipe (67a) is provided with a plurality of different layers along the longitudinal direction of the upper extension pipe (62). And according to the upward pressure on the floor of the building, when the water pressure is relatively high, that is, when the groundwater is excessively concentrated in and around the building (hereinafter referred to as the first case), the groundwater is discharged more smoothly To this end, the auxiliary connecting pipe (67a) located in the lower floor is opened, so that the ground water is quickly discharged.

And when the water pressure is relatively low, that is, when the groundwater is excessively concentrated around and below the building (hereinafter referred to as the second case), by opening the auxiliary connector 67a located on the upper floor, To be discharged relatively less quickly than in the first case.

As such, in a special situation such as heavy rain or rainy season, the ground floor is differentially discharged by using an auxiliary connecting pipe 67a provided on different floors depending on the amount of groundwater that is collected around and under the building. The upstream pressure on the tank is kept constant and adjusted.

4B and 4C, the upstream hydraulic pressure control structure of the present invention has an auxiliary connector 67b protruding from the upper extension tube 62 and is formed to extend to the lower extension tube 64, thereby supporting the auxiliary connector ( One side of the 67b) is connected to the upper extension tube 62, the other side is formed to be connected to the lower extension tube (64).

The auxiliary connecting pipe 67b formed as described above is connected to the lower extension pipe 64 as compared to the auxiliary connecting pipe 67a of FIG. 4A, and thus the pressure reducing pipe 60 is formed in a more rigid structure. Due to the more efficient maintenance and repair, there is a relatively less noise caused by the height difference falling of the groundwater.

Although the present invention has been described in detail in the above embodiments, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical spirit of the present invention, and such modifications and modifications belong to the appended utility model claims.
