Description

Combination type telescopic support for water pipe or sewage pipe {COMBINATION TYPE ELASTIC SUPPORT FOR WATER PIPE OR SEWER PIPE}

The present invention relates to a combined expansion and contraction pedestal for a water supply pipe or a sewage pipe, and more particularly, to a coupling type expansion and contraction pedestal for a water supply pipe or a sewage pipe that can prevent the pipe from being separated during backfilling during construction.

In general, a water supply pipe that supplies water to factories, houses, and various facilities, and a sewage pipe capable of transporting used wastewater to a remote sewage treatment facility are buried underground to secure space on the ground and beautify the living environment.

The burial of the water and sewer pipes is performed by cutting the ground into a sufficient space in which a structure connecting a plurality of water and sewage pipes having a certain diameter and length in a row in communication can be seated, and the water and sewage pipe structures are sequentially installed there along the longitudinal direction. After it is settled, the construction is completed by burying it with soil.

Looking at this conventional burial method, since it is a method of simply digging the ground, putting water and sewage pipes there, and then covering the ground again, construction is simple and widely used.

In particular, in the case of downtown areas, by compacting the soil located in the periphery of the water and sewer pipes to increase the density between the soil and soil, while applying concrete or asphalt on the ground where the water and sewage pipes are buried, the water and sewage pipes caused by subsidence and collapse of the ground The risk of breakage is minimized.

Therefore, in the laying of water and sewage pipes, the above-described construction method was sufficient to achieve the purpose without a separate reinforcement work, and there was no particular problem in the stability of the water and sewage pipes.

In this regard, Patent Registration No. 10-0654754, "a device for protecting water and sewage pipes that can withstand vertical pressure in an apartment building," and Patent Registration No. 10-0659396, "a structure for supporting water and sewage pipes that are easy to assemble and replace" have been disclosed. there is.

However, in places where ground collapse and partial subsidence are frequent, such as river basins or mountainous areas with a lot of precipitation, there is a limit to burying water and sewage pipes using the above construction method alone.

That is, in the above construction method, the water and sewer pipes are long connected in one direction and the bearing capacity against lateral pressure is very weak, so even a slight subsidence of the ground in the buried ground water and sewage pipes can easily bend or twist the water and sewage pipes, resulting in breakage and gaps in some of them. In addition, leakage and inflow of external foreign substances may occur through these gaps.

In order to solve this problem, the wires connected to a number of anchors fixed to the ground are firmly connected to the outer peripheral surface of the water and sewage pipes buried underground, so that they can be supported to some extent without bending or distortion of the water and sewage pipes even under partial ground subsidence. A. It has been previously applied for and registered as "Safety Structure for Landfill of Sewer Pipes" of Utility Model Registration No. 20-318224.

However, the previously applied design has a limit in the power that can be sustained, and thus the fundamental solution of the above problem has not been achieved.

Above all, the prior art described above had a problem in that it lacked durability against distortion or settling of the pipe connection part due to an external force caused by an earthquake in recent years, and structural strength was also weak.

As such, the prior art had a problem in that, when an impact load caused by an earthquake or unexpected vibration occurred, the cumbersome work of excavating and re-constructing the constructed land due to damage or distortion of the pipe connection part had to be added.

Registered Patent No. 10-0654754 Registered Patent No. 10-0659396 Registered Utility Model No. 20-318224

In addition, the rod receiving cylinder 260 is to accommodate each of the first rotational rod 242 and the second rotational rod 252 in and out.

Here, the rod receiving cylinder 260 is operated by fluid pressure to allow entry and exit of the first rotation rod 242 and the second rotation rod 252 .

That is, the construction target surface 400 on which the first fastener 201 and the second fastener 202 are respectively installed is not flat as in FIG. 7, or the first fastener 201 and the second fastener ( 202) is to maintain the airtight and watertight state of the connection body 110 even when the respective centers are not arranged on a straight line and a step occurs.

To this end, the first rotating body 241 and the second rotating body 251 are rotatably mounted with respect to the first fastener 201 and the second fastener 202, respectively, and at the same time, the first rotating rod 242 and the second rotating body 251 The two rotation rods 252 are respectively rotatably mounted to the first rotation body 241 and the second rotation body 251 .

Therefore, the rotation structure including the above-described rod accommodating cylinder can maintain airtightness and watertightness even when the connection portion between the first pipe 310 and the second pipe 320 is misaligned due to torsion and settling to a certain extent. .

On the other hand, the second unit 200, as shown in FIG. 8, is also possible to apply an embodiment in which the seismic isolator 280 is further provided together with the floor adjusting rod 270 that is mounted on both ends of the pedestal 230 so as to be height-adjustable. is of course

Here, the bottom adjustment rod 270 may further include male threads 271 formed along the outer circumferential surface so as to be screwed with respect to both end sides of the pedestal 230 .

In this case, the seismic isolator 280 may include an adjustment rod rotating shaft 281 coupled through the floor adjustment rod 270 in a direction orthogonal to the floor adjustment rod 270 .

In addition, the seismic isolator 280 may include a support block 282 coupled to the rotation shaft of the adjustment rod to support and support the floor adjustment rod 270 .

In addition, the seismic isolator 280 may include a dispersion block 283 mounted on the lower surface of the support block 282 to allow elastic deformation.

In addition, it goes without saying that the seismic isolator 280 may include a metal seismic isolator 284 embedded in the dispersion block 283 and disposed to be spaced apart from each other in upper and lower stages.

In the above-described seismic isolating piece 284, a plurality of one side piece (284a) and a plurality of other side piece (284b) are alternately arranged as if interlocking fingers, so that they are stacked in upper and lower multi-stage, respectively, but each of the seismic isolating pieces may be arranged parallel to each other. will be.
