Support structure of landfill fume pipe {SUPPORTING CONSTRUCT FOR HUME PIPE}

The present invention secures the airtightness of the connection portion of the fume pipe by maintaining the hume pipe (Hume Pipe) continuously buried in the ground for a smooth drainage of general sewage, sewage, waste water, etc. The present invention relates to a supporting structure of a landfilled fume pipe, which can be made at the same time, to prevent uneven settlement between the fume pipes and to make construction easier.

Hume pipes buried in the ground, such as wastewater pipes, such as general sewage pipes, are made into a cylindrical cylinder of a predetermined standard and are connected to each other to form a pipeline to drain water to a conventional sewage treatment facility.

In the case of sewage, sewage, and wastewater flowing along the pipeline, a large amount of sediment is contained, so when these sediments accumulate on the inner surface of the sewage pipe, the effective pipe diameter of the fume pipe gradually decreases, and smooth drainage does not occur. It may be a cause of occurrence, and if there is a large amount of rainfall in the rainy season, there may be a problem that the sewage backflow due to the lack of water supply capacity.

Therefore, in order to prevent such a phenomenon, when installing a fume pipe, most of them have a certain inclination so that the flow rate of sewage flowing through the inside of the fume pipe maintains a minimum flow rate or more.

As a method for constructing a general fume pipe, as shown in FIG. 1, another fume pipe 1 in a state in which a watertight belt 3 is inserted into and connected to an inner surface of a socket part 2 formed on one side of the fume pipe 1. ) Is seated on the earth's surface as it is tied in the horizontal direction.

However, in this manner, as shown in FIGS. 2A and 2B, the lower sag of the socket part 2 may cause the flow of wastewater and wastewater to be stagnant, as well as the socket part 2 of the fume pipe when left for a long time. Is corrosive or cracks (A) can cause effluent and waste water leakage.

In addition, when the fume pipe (1) is to be installed, the center of the fume pipe must be finely adjusted by using a mechanism such as a chain block, and requires the skill of the operator, and the concrete foundation to reinforce the soft ground or the high pressure pipe. In order to install the project, it requires complicated construction work such as input of a large number of workers and concrete curing due to formwork installation and site casting.

As a technology disclosed in consideration of such a conventional problem, Korean Patent No. 0864768 discloses a "fume pipe embedding construction method" for quickly and accurately installing a fume pipe buried in the ground.

This technology is to construct the struts at the starting point and the end point of the excavation section where the fume pipe is installed, and connect the thread to both struts according to the inclination value, and arrange the upper end of the supporting block in a straight line according to the excretion height. In order to install the fume pipes by placing the fume pipes in the settling section and connecting them in a line, and filling the gaps of the fume pipes with non-woven rolls and mortars and reinforcing concrete, the fume pipes can be buried.

In addition, `` Registered Utility Model No. 0274837 '' uses a ready-made supporting concrete to install a fume pipe, so it is not necessary to install a separate formwork, which can shorten the construction period and install a fume pipe. Structure] is disclosed.

However, in the prior art as described above, erroneous waste water is easily leaked due to poor surface flatness, sagging due to the weight of the fume pipe, and poor construction of the fume pipe connection portion, so that technical skills of field personnel are required, and they occur between each other. Due to the sedimentation, the sedimentation, decay and odor of sewage are caused, as well as groundwater or surrounding soil inflow, which causes the road to sink.

Moreover, since various subsidiary materials have to be installed in the pipeline, the workability is greatly reduced and the cost is increased, and there is a problem that the maintenance work must be frequently performed due to leakage occurring at the joint of the fume pipe.

On the other hand, in view of such a prior art, Korean Utility Model Registration No. 0318079 discloses a `` sewage pipe-fume pipe '' to support a fume pipe buried for drainage of sewage or sewage, and a connection part between these fume pipes to prevent inequality settlement between the fume pipes. A technique for laying a pedestal is disclosed.

In this case, however, the pedestal is separated into an outer and an inner support plate, and at the same time, a connecting surface and a groove are formed on the inner support plate, so the assembling work of the pedestal itself and the installation of the pedestal in the longitudinal direction are connected to each other. There is a problem that this is quite difficult.

In addition, as the connecting surface and the groove portion of the pedestal is made to match the fume pipe, a large problem occurs in the construction of the fume pipe must be seated in the correct position on the upper side of the pedestal.

In addition, as the soil penetrates into the space between the fume pipe and the pedestal, the bearing capacity of the fume pipe is weakened, and as a result, the connection part of the fume pipe is distorted, thereby causing leakage.

The present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to allow a fume pipe to be hypothesized while continuously connecting a block having a binding means to the bottom of a pipeline on which underground fume pipes are seated. The present invention provides a support structure for a landfilled fume pipe that can reliably prevent uneven settlement of a connection portion of a fume pipe and has excellent workability.

3 to 12C are views for explaining the supporting structure of the buried fume pipe according to the present invention. First, as shown in FIGS. 3 and 4, including a general sewage pipe, the soil may be underground, such as a wastewater pipe. The conventional fume pipe 10 embedded in the cylindrical shape of a predetermined standard is formed in a pipe line by connecting them in series with each other through the socket portion 11b connected to the inclined surface 11a at one end portion thereof.

In addition, between the fume pipe 10 and the bottom surface of the ground, one unit chain block 20 for maintaining the pipeline more robust and stable as the same structure is formed in a continuous structure with each other to form a supporting structure.

As shown in FIGS. 5 to 7a and 7b, these blocks 20 are made of a hard synthetic resin and are manufactured to an appropriate thickness and length to sufficiently support the fume pipe 10. The surface is formed so that the cylindrical body of the fume pipe 10 can be stably seated by forming a substantially hemispherical circular arc groove 21 in the longitudinal direction.

In addition, the inclined surface including the fume pipe 10 is formed in the substantially central portion of the block 20, the inclined portion 22a and the stepped portion 22b are formed from the arc groove 21 and the enlarged groove 23 is expanded in diameter. 11a and the socket part 11b can be mounted as it is.

A plurality of lattice-shaped grooves 24a are formed on the rear surface of the block 20 so as to be symmetrical with each other so as to reinforce the binding force with the bottom surface of the conduit, and a plurality of through holes 24b are provided at a predetermined position. In accordance with the construction of the block 20 on the bottom surface of the pipeline can be accommodated for the negative pressure generated by the sewage or waste water.

In addition, the ridge portion 25 is formed at the longitudinal edge of the block 20 to be in close contact with the body circumferential surface of the fume pipe 10, and is configured to prevent inflow of soil in advance. At both edges of the block 20, a binding means for continuously connecting the blocks 20 to each other is continuously provided.

The binding means is composed of a male binding portion 26A and a female binding portion 26B, and the male binding portion 26A includes a pair of insertion grooves 27a formed at the lower end of the arc groove 21, both ends thereof. It is composed of a locking piece 29 having a reinforcing projection (28a) at the edge, the female binding portion (26B) is formed on a pair of fitting pieces (30a) formed at the bottom of the arc groove 21 and the edges thereof The reinforcement protrusion 31a and the locking groove 32 are provided.

With this configuration, as shown in Figs. 10A and 10B, the insertion groove 27a and the locking piece 29 of the male binding part 26A are fitted with the fitting piece 30a and the locking groove (of the female binding part 26B). It is possible to arrange the blocks 20 continuously by being assembled to 32.

Meanwhile, as shown in FIGS. 5 and 6, the main cover body 33A or the auxiliary cover body 33B is selectively mounted in the enlarged diameter groove 23 of the block 20 so that the cylindrical body or the socket of the fume pipe 10 may be installed. The part 11b can be supported more stably.

That is, as shown in FIGS. 11A to 11C, the main cover body 33A has a pair of engaging protrusions 34a at both ends of the body coinciding with the arc groove 21 of the block 20 and the center of the front part of the body. The auxiliary protrusions 34b are formed downward in each of the auxiliary protrusions 34b to be assembled into the fastening grooves 35a provided at the edges of the enlarged grooves 23 of the block 20.

In addition, as shown in FIGS. 12A to 12C, the auxiliary cover body 33B has a locking protrusion 36a downwardly formed at both ends of the body that coincides with the arc groove 21 of the block 20 so that the block 20 may be formed. In the state in which the socket portion 11b of the fume pipe 10 is seated by the enlarged diameter 23 of the assembly, the fastening grooves 35a are assembled so that there is no space between the fume pipe 10 and the block 20.

5 and 6, the through holes 35b are formed on one side of the ridge 25 connected to the arc groove 21 of the block 20 so that the through holes 35b face each other. The fastening band 37 is fitted so that the hume tube 10 and other flexible tubes and the like can be bundled and firmly fixed.

The present invention configured as described above, first digging the ground to a certain depth in the ground surface for sewer or drainage construction, and then sequentially arranged blocks 20, a plurality of lattice type on the bottom surface of the block 20 Since the groove 24a is provided, the material consumption and weight can be reduced, as well as the binding force with the bottom of the pipe can be further increased.

In addition, if water such as sewage or sewage is present on the bottom of the pipeline in the process of constructing the block 20, the water may be discharged toward the surface through the through hole 24b, which may occur in the process of seating the block 20. It will accept negative pressure.

When forming the supporting structure by the block 20, the block 20 by the male binding portion 26A and the female binding portion 26B formed at both edges once any one of the blocks 20 is seated. It can be configured by connecting consecutively.

That is, the insertion groove 27a and the locking piece 29 formed in the male binding part 26A are positioned so that the fitting piece 30a and the locking groove 32 of the female binding part 26B are positioned and then fitted to each other. It can be combined easily according to, it is possible to maintain a firm binding force by the reinforcing projection (28a) of the male binding portion (26A) and the reinforcing projection (31a) of the female binding portion (26B).

As such, the fume pipe 10 is mounted and connected to each other in a state where the alignment of the block 20 is completed. In this case, an arc groove 21 and an enlarged diameter groove 23 formed on the surface of the block 20 are used. Thus, the fume pipe 10 can be stably mounted.

In other words, the surface of the block 20 includes an arc-shaped groove 21 having the same shape as the circumferential surface of the body of the fume pipe 10 having a cylindrical shape, and the enlarged groove formed by the inclined portion 22a and the stepped portion 22b ( Since 23 is formed, the inclined surface 11a and the socket portion 11b constituting the fume pipe 10 are formed in the circular groove 21 and the enlarged diameter groove 23 of the block 20 using ordinary work equipment. It can be seated as it is.

At this time, when the cylindrical body of the fume pipe 10 is disposed on the enlarged groove 23 side formed in the block 20, the enlarged groove (34a, 34b of the main cover body 33A) is used in advance. The fume pipe 10 can be stably fixed in a state in which the circular groove 21 and the surface coincide with each other without being inserted into the fastening groove 35a of the 23).

In addition, in the case of the enlarged groove 23 into which the inclined surface 11a and the socket portion 11b of the fume pipe 10 are fitted, a free space is formed according to the width dimension, so that the protrusion of the auxiliary cover body 33B is attached to this portion. The space 36a can be inserted into the fastening groove 35a of the enlarged diameter groove 23 so as not to create a space.

The reason why the expansion groove 23 formed in the block 20 is made wider than the socket portion 11b of the fume pipe 10 and blocked by the auxiliary cover body 33B is because the fume pipe 10 is seated on the block 20. In order to facilitate the arrangement of the fume pipe 10 by securing the fluidity in the horizontal direction according to the position of the fume pipe 10 in the process.

That is, in the past, the operator had to settle while inducing the fume pipe 10 to the correct position in the state in which the block 20 is placed, but the enlarged groove 23 of the block 20 is the fume pipe 10. It is about twice as wide as the socket portion (11b) of the will be able to improve the inconvenience of working to precisely position.

In addition, in order to connect the fume pipe 10 in series, one fume pipe 10 is mounted on the block 20 while the other fume pipe 10 is mounted horizontally on the block 20, and then the fume pipe is already seated. Since it can be easily fixed by being inserted into the socket part 11b while moving horizontally to the (10) side, it does not need much skill.

On the other hand, the construction of the fume pipe (10) is installed after connecting a plurality of blocks 20 on the bottom surface of the ground installed by installing a fume pipe (10) on the upper surface of each block 20 or each block 20 and the fume pipe (10) can be installed alternately, which can be appropriately selected according to the convenience of work in the construction of the fume pipe (10) and the surrounding working conditions.

In addition, when the fastening band 37 is assembled with the through hole 35b formed in the arc groove 21 of the block 20, the body circumferential surface is tied up even in the case of a flexible fume tube 10 as well as a flexible tube. The fluidity can be suppressed.

In this way, after the binding of the fume pipe 10 is made, it is possible to complete the construction of the sewer or drain by covering the soil on the pipeline and embedded in the ground.

The technical problem of the present invention is achieved by the technical configuration as described above, although the present invention has been described by a limited embodiment and drawings, the present invention is not limited thereto but by those skilled in the art to which the present invention pertains. Various modifications and variations are possible, without departing from the spirit and scope of the appended claims.
