The present invention relates to a flexible pipe pedestal for supporting a pipe buried underground, more specifically, to the industrial waste such as waste tires, waste synthetic resin, or PE (polyethylene), PP (polypropylene) -based synthetic resin, glass fiber, etc. The present invention relates to a flexible pipe pedestal, which is formed of a dual structure of ductility and rigidity to support a synthetic resin pipe, thereby preventing deformation of the synthetic resin pipe due to earth pressure and allowing easy operation regardless of the environmental conditions of the construction site. .

In general, sewage disposal facilities are buried underground, so they do not usually feel the value of their existence, but they are very valuable national infrastructures that do not use a single day.

However, sewage conduits are not only exposed to moisture and rapid temperature changes underground, but also due to earth loads such as earth pressure, water pressure, and live loads, so that aging progresses faster than other facilities on the ground.

Due to the many problems of sewage pipes, it is true that pollution of groundwater and soil is extremely threatening the water supply of the whole people.

Therefore, it is now time to promote the sewage pipe maintenance project as a major national policy project to repair and reinforce sewage pipes that are structurally and mathematically ineffective.

The Ministry of Environment has made such a sewage pipe maintenance project in the BTL (Build TTransfer Lease) method for the next 10 years. , Cast iron pipes, etc.) cannot be guaranteed for the next 20 years by the government, so it is urgent to improve and develop sewage pipe construction systems. There will be no.

Conventional domestic sewage pipes have used hume pipes and cast iron pipes mainly made of cement concrete as the rigid pipes mentioned above. , Such as short circuits, short circuits, etc., causes large amounts of unknown water (groundwater, tap water, surface water, river water, etc.) to flow through and inflow of sewage corresponding to the amount of inflow, and decrease in efficiency of sewage treatment due to inflow of unknown water. In addition, the development of sewage pipes using flexible pipes, such as PE and PVC, has been accelerated in western developed countries and Japan because they have not been able to actively cope with ground subsidence and earthquakes.

However, the problems with the flexible sewer pipes are not overlooked. Therefore, the optimized construction methods that meet the merits of the material have not been developed until now.

Accordingly, it would be optimal to search for a method in which flexible sewage pipes caused by earth pressure, vibration, and various unknown waters fundamentally prevent deformation and can be piped to avoid underground buried materials (obstructions).

The flexible pipe itself is inevitably deformed by load, but maintains the original pipe shape by the stability of the ground after buried.

Rigid pipes are supported by the rigidity of the pipes rather than depending on the stability of the ground.

The cause of deformation in the flexible pipe is ㉠. In the construction process, if the compaction of 'a' part has no special compaction method other than natural compaction by watering, and the compaction of 'a' part is compacted to 94% or more, the flexible pipe itself is injured by the change of the surrounding ground. Or a left or right shift occurs, resulting in poor end gradient.

Iii. As the compaction of the 'a' part is poor, the 'b' part becomes loose due to the load, vibration, rainwater and groundwater flow due to the traffic on the upper road surface. Deformation occurs in the flexible tube.

Iii. The deformation of the flexible pipe is not the rigidity of the pipe but the construction is an important factor of the pipe deformation.

In addition, in the prior art, the base portion in which the flexible pipe is installed and the portion a of FIG. 1 are filled with sand to promote the depletion of resources, resulting in an increase in price, and there is a problem of improving the environmental breakdown and construction costs by sand extraction.

In order to solve the above problems, a solution is disclosed in Korean Laid-Open Patent Publication No. 2006-0005497 (hereinafter referred to as "conventional design"), and its configuration is as shown in FIG. 3 or 4.

Briefly describing the configuration of the prior art, the curved support plate 100 having a curvature corresponding to the curvature of the cylindrical tube is formed, it is composed of a support member 110 for supporting the curved support plate from the bottom.

The conventional design configured as described above can not produce a large amount of pedestal in a short time because the tube pedestal is formed through the injection.

And because the conventional design is produced by the injection does not cope with the situation that occurs in the field, which is produced by the injection, there is a problem that it is difficult to use by cutting or extending the length.

In other words, the product produced in a fixed size can not be used to reduce the length or increase the length in accordance with the situation occurs in the field it is very difficult to produce a separate size to use.

Another embodiment of the present invention is a curved support plate 100 having a curvature corresponding to the flexible tube curvature of the cylindrical; A support member 110 for supporting the curved support plate 100 from the bottom; And an outer cover 120 coupled to the edge of the curved support plate 100 and surrounding the side surface of the support member 110.

The conventional design configured as described above has a problem in that the production is not smooth and the yield decreases.

That is, since the curved support plate 100 and the support member 110 are produced through injection, and assembled to form a single pipe pedestal, the product production process is very complicated, and a lot of time and personnel are required to produce a pedestal. There is a problem to be administered.

In addition, since the support member 110 has a vertical support plate and a horizontal support plate in the form of a lattice in the inner side of the outer cover, it is very difficult to install the pedestal when the floor on which the pipe 2 is seated is not evenly formed. As the expansion of the pipe is transmitted to the pedestal due to the difference in temperature, wetland, temperature, etc., the state in which the pedestal is installed does not maintain a horizontal state, and thus deformation occurs, which causes the pipe to be twisted. There is a problem in which water leakage occurs in the connecting portion.

Since the pipe support is not installed horizontally, there is a problem that the pipe is cracked by the pressure applied from the ground.

The present invention for solving the above problems by using industrial wastes such as waste tires, waste synthetic resins, etc. or using heterogeneous materials having different strengths using external materials such as PE (polyethylene), PP (polypropylene) -based synthetic resins, glass fiber, etc. It is an object of the present invention to provide a flexible pipe support for absorbing the shrinkage and expansion coefficient of a pipe, thereby preventing deformation of the pipe.

In addition, an object of the present invention is to provide a flexible tube pedestal to facilitate the installation of the pedestal supporting the tube even if the floor on which the tube is installed does not maintain a horizontal state.

In addition, a flexible pipe pedestal composed of a material having a different strength, and when the external pressure is applied, the shape of the flexible member to the pedestal is deformed to distribute the pressure transmitted to the pipe to prevent the pipe from being deformed. The purpose is to provide.

In addition, the pipe base is produced using extrusion, so that it can be cut and used to the required length in the field, so that it can cope with the situation occurring in the field. Compared with the above, the purpose is to provide a flexible pipe pedestal with low production cost because it prevents the labor cost according to a separate assembly process.

In addition, it is an object to provide a flexible pipe pedestal to contribute to the national industrial development because it uses waste resources such as industrial waste, such as waste tires, waste synthetic resins.

The present invention for achieving the above object is a support panel formed to correspond to the curvature of the tube by extrusion using a soft synthetic resin; A pressure dispersing member formed by extrusion using a soft synthetic resin on an upper portion of the supporting panel; It consists of a leg member formed by extrusion using a hard synthetic resin to support the backing panel and the pipe at the bottom of the backing panel, the backing panel, pressure distribution member, the leg member is characterized in that the flexible member is formed by extrusion Provide a support base.

In addition, each of the soft and hard raw materials (industrial wastes such as waste tires, waste synthetic resins, or PE (polyethylene), PP (polypropylene) -based synthetic resins, glass fibers, etc.) is respectively melted in a gel state by high heat. A raw material feeding step of transferring raw materials in a molten gel state, respectively; When the raw material in the gel state is transferred, the support panel and the pressure distribution member are formed by soft synthetic resin, and the leg member is formed by hard synthetic resin. When each molding is completed, the leg member is placed on the bottom of the support panel. Forming process to be fused; A cooling step of cooling the support panel, the pressure dissipating member, and the leg member in a state through a molding process so as to be formed firmly; It provides a method for producing a flexible tube pedestal, characterized in that the cutting step of cutting the formed pedestal to the required length in the field through the cooling process.

Hereinafter, the flexible tube pedestal according to the present invention will be described in detail through the accompanying drawings.

5 to 12, the present invention has a round shape at a predetermined angle and is formed of soft synthetic resin, and industrial waste or PE (such as waste tire, waste synthetic resin, etc.) to support the pipe (2). The flexible support panel 10 is formed by extrusion using polyethylene), PP (polypropylene) -based synthetic resin, glass fiber, or the like.

In addition, as shown in the drawing, in another embodiment, a plurality of through holes 11 are formed in the support panel 10 so that the pressure is dispersed when pressure is applied from the outside.

In addition, when the tube (pipe) is seated on the upper portion of the support panel 10, the bent portion 12 is formed at the bottom so that the support panel surrounds the tube by the weight of the tube itself.

The cylindrical pressure distribution member 20 is installed on the upper portion of the support panel 10 so as to prevent the twisting phenomenon from occurring in the pipe 2 by the pressure applied from the outside.

The pressure distribution member 20 is formed in a plurality of cylindrical forms as shown in the upper portion of the support panel 10 in close contact.

As shown in the figure, the pressure dissipation member 20 is formed in a soft wave shape on the top of the support panel 10 so as to disperse the pressure when an external pressure is applied to the pipe 2.

The pressure dissipation member 20 is formed in a conical shape as shown in the figure is formed on the flexible support panel 10 to the top so as to disperse the pressure when an external pressure is applied to the pipe.

A space 21 is formed between the support panel 10 and the pressure dissipation member 20. When the external pressure is applied to the pipe 2, the space 21 is deformed in the pipe 2 itself. In order to prevent the pressure distribution member 20 provides a space that can be deformed.

And the pressure distribution member 20 formed in a conical shape on the upper portion of the support panel 10 forms a space 21 between the pressure distribution member 20 and the pressure distribution member 20 to the pipe (2). It is possible to disperse the external pressure applied, wherein the shape of the cone-shaped pressure distribution member 20 is deformed while dispersing the pressure.

Leg members 30 are formed in the bottom of the support panel 10 in the longitudinal direction, and industrial wastes such as waste tires, waste synthetic resins, or polyethylene (PE), so as to support the pressure applied to the flexible support panel 10, PP (polypropylene) -based synthetic resin, glass fiber (fiber glass) and the like is formed by hard extrusion.

The supporting panel 10, the pressure distribution member 20, and the leg member 30 described above are configured in a shape as shown in the drawing through extrusion using a mold.

In the manufacturing process of the pedestal configured as described above, the raw materials (soft tires, waste synthetic resins, industrial wastes, PE (polyethylene), PP (polypropylene) -based synthetic resins, glass fibers, etc.) are inputted at high temperatures. A raw material input step of melting the raw material in a melted gel state by melting the gel in a gel state; When the raw material in the gel state is transferred, the support panel 10 and the pressure distribution member 20 are molded by soft synthetic resin, and the leg member 30 is molded by hard synthetic resin, and each molding is completed. If so, the molding process for fusion bonding the leg member 30 to the bottom of the support panel 10; A cooling step of cooling the support panel 10, the pressure distribution panel 20, and the leg member 30 having a predetermined shape through the molding process so as to be firmly formed; It consists of a cutting step of cutting the pedestal (1) is completed to the required length in the field through the cooling process.

In more detail the process produced by the above process and the above, soft, hard raw materials are introduced into a common hopper (not shown). Raw materials fed into the hopper are separated into soft and hard materials and put into the hopper.

The input raw material is heated at high heat to be melted and transported in a gel state. At this time, soft and hard materials are heated and transferred in a gel form.

The melted and conveyed gel liquid is supplied to an extruder (mold) which is extruded in the form of a pedestal 1 as shown in the drawing. In the case of a material in which soft material is melted in a gel state, the supporting panel 10 ) Is put into the extruder forming the leg, and in the case of a material in which the hard material is melted in a gel state, it is put into the extruder forming the leg member 20.

In addition, in the case of the pressure distribution member 20 formed on the upper portion of the support panel 10, an extruder is formed so as to be integrally formed with the support panel 10, and a soft material in a gel state is introduced as shown in the drawing. Cylindrical, wavy, conical, etc. are formed.

When the pressure dissipation member 20 and the support panel 10 pass through the extruder, the leg member 30 formed at the bottom of the support panel is fused to the support panel 10 via the extruder. do.

Cooling is performed so that the leg member 30 is welded to the bottom of the supporting panel 10 so as to be firmly fixed so as to be configured as shown in the drawing.

When the molding is completed through the process as described above, it is cut to the required size in the field, at this time can be provided to the required size in the field because it is cut by adjusting the length of each according to the circumstances.

Since it is supplied by the manufacturer in the required size in the field, the process for installing the pedestal 1 is made easier, which takes significantly shorter time than the conventional pedestal construction.

It describes the process of installing the flexible tube pedestal of the present invention produced by the above process.

A pit is formed at a predetermined depth in a place for installing the pipe 2, and the pit simply arranges only the position where the pedestal 1 can be placed without performing the foundation work as in the prior art.

After arranging the inside of the pit a little, the pedestal 1 is fixed to a predetermined position. At this time, since a plurality of leg members 30 formed at the bottom of the support panel 10 are formed in a plurality, it is very convenient to level them. .

In other words, in the prior art, since the entire surface of the pit was flattened due to contact with the ground of the pit, the pedestal 1 was installed to maintain a horizontal state. However, the present invention does not perform the overall flat work (foundation work). Even if the leg member 30 formed in the bottom of the support panel 10 is in contact with the ground of the pit is significantly narrow, it is very easy to maintain a horizontal state even without the foundation work.

When the tube 2 is installed on the upper part of the support panel 10 after the pedestal 1 is installed in the pit, the support member 10 surrounds the pipe 2, which occurs in the support panel 10. The pedestal 1 is configured to surround the tube by the bent portion 12 formed at the bottom.

And since the pressure distribution member 20 formed on the upper portion of the support panel 10 and the support panel 10 is formed soft, even if pressure is applied from the outside of the pipe (2) and the pressure distribution member 20 made of soft The pressure is dispersed by the support panel 10 so that deformation of the pipe 2 does not occur.

That is, since the space portion 21 is formed between the pressure distribution member 20 and the support panel 10, the pressure dispersion member 20 expands to the space portion 21 even when an external pressure is generated, so that the pipe 2 The whole shape can be prevented from twisting.

In addition, if the temperature change occurs severely, such as winter or summer, uneven settlement may occur in the ground, but the pipe (2) is the pipe (2) by the flexible support panel 10 and the pressure distribution member (20) At the same time as supporting the bottom and side of the hard leg member 30 is supported so as to prevent the pipe (2) to be twisted to prevent the occurrence of leakage in the part where the pipe (2) and the pipe (2) is connected Can be.

As described above, the flexible pipe pedestal of the present invention is not produced by injection, but produced by extrusion as in the prior art, so that the production is easier than the conventional pedestal, and the productivity is significantly improved than the production by injection in the same time. It works.

In addition, since the pedestal is produced by extrusion, the process of producing a product is simplified, and thus, it takes less time and manpower to produce than the conventional pedestal.

In addition, since the pedestal is easily installed even if the foundation work for installing the pipe is not performed, the construction can be carried out within a shorter time than the time for installing the conventional pedestal, and the construction is simple since the work such as the foundation work is not performed during the construction. Termination is effective.

In addition, as the expansion of the pipe is transmitted to the pedestal due to the difference in wetlands, temperature, etc., the pipe is twisted due to an uneven settlement phenomenon, so that a leak occurs. By spraying, there is an effect of preventing the pipe from twisting.
