Description

HOUSING FOR PIPE PROTECTION

The present invention relates to an apparatus for protecting pipelines, and in particular, the pipelines in special sections, such as soft ground or vehicle traffic sections, by covering the entire pipeline to distribute the load applied from the upper side while stably supporting the lower part of the pipeline without damage or deformation. It also relates to a pipeline protection housing that does not require the use of expensive filling soil, which has to be filled to protect the pipeline.

In general, large and small pipelines are used in various ways to supply water to homes or factories, or to discharge various wastewater and wastewater. These pipelines are mainly used underground in the state of aesthetics and function.

The laying of these pipelines is carried out by considering the type of the pipeline, soil, bearing capacity, construction method, load condition and embedding condition, durability and economics of the pipeline and selecting the appropriate method.

At this time, the laying work should be considerably careful. If the foundation hole is poor, not only the sedimentation of the pipe can cause the congestion of sewage, rot and odor, but also in the worst case, the pipe can be broken and leak or groundwater. This may be due to the intrusion of sediment around the pipeline and severe roads.

1 and 2 is a cross-sectional reference for illustrating one of the prior art for embedding the pipeline underground.

As shown, in the prior art, using a device such as an excavator to excavate the ground to the desired depth and then dig the filling soil (A, B, C) filling the pipeline 1 step by step. If the place where the pipeline 1 is buried is soft ground, a complicated additional work of exposing the soft ground to fill the crushed stone and compacting it was preceded.

Then, the filling soils (A, B, C) are filled in stages, and the types and filling methods of the filling soils (A, B, C) are defined in consideration of the type and soil of the pipeline (1). It should be implemented by applying the standard. If the pipe (1) is a soft pipe of the filling soil (A, B, C) is mainly used sand, the basis of this will be described below the buried process of the pipe (1).

If the pipeline (1) is a flexible pipe, it is specified as a sand base 360 ° according to the Sewage Facility Standard (Ministry of Environment), which is being revised. That is, it is specified that it is preferable to use sand as the filling soil, and to have the thickness of the sand laid under the pipe line be 100 to 300 mm, and to refill the sand from the top of the pipe line to 200 mm in the future.

Accordingly, first excavate and excavate the ground as shown in FIG. . At this time, the reinforcing effect of the pipeline 1 varies depending on the width (or bearing angle) of the sand base in contact with the pipeline 1, and the load bearing capacity increases as the bearing angle increases. The important point is to secure the necessary angle of support, and to do so, it is necessary to increase the angle of support in construction. In the case where the conduit 1 is a flexible pipe, it is preferable that the sand foundation supports about 120 ° of the conduit 1. For reference, when the pipe (1) is a flexible pipe, it is usually constructed as a sand foundation. However, when the pipe (1) is a rigid pipe, it is constructed with various types of foundation holes such as sand foundation, crushed stone foundation, reinforced concrete foundation, concrete foundation, and pile foundation. .

Subsequently, the bottom of the conduit 1 is filled with sand so that the bottom of the pipe 1 is at least 120 ° to 180 ° above the first sand foundation (part A), which is compacted as shown in FIG. Compact (B). This is to prepare for the problem that the pipe 1 is deformed into a flat spread shape due to the influence of the load acting between the support angle 90 ° to 120 °. In the figure it is shown that the lower part of the conduit to fill up to 180 ° to more stably prepare for the load.

After that, the sand is filled to the level covering the upper end of the pipeline (1) and the water is compacted to the third sand foundation (part C). The sand foundation 360 ° standard according to the 'Sewage Facility Standard (Ministry of Environment)' is currently being revised. Apply. This is to minimize the damage of the pipeline (1) due to the rough soil in preparation for the deformation of the pipeline (1) due to the applied load.

And finally, the buried work of the pipeline 1 is completed by covering the surface area using the original soil (D) generated during the excavation.

 However, according to the buried method of the pipeline 1 according to the prior art, if the place where the pipeline 1 is embedded is a soft ground, additional work, which requires a lot of complicated expenses such as exposing the soft ground and filling and crushing the stone, should be preceded. There was a problem. This is because in soft ground, some sections of pipeline 1 are settled and foreign substances flowing in pipeline 1 with sewage gradually accumulate, which leads to fatal consequences that the flow path is reduced and the flow of sewage is completely blocked. . Although the degree of deformation is different depending on the type of pipe 1, the deformation continues continuously when the strain exceeds 5% of the allowable strain, and in the worst case, the pipe 1 is broken and leaks or groundwater occurs. As a result of the intrusion of the sediment around the pipeline (1) inflow and severe roads also appeared to sink.

In addition, when the place where the pipeline 1 is buried is a special section to which an irregular and excessive load is applied, such as a railroad or a vehicle passing, a problem occurs that the pipeline cannot endure excessive load and is damaged. To prevent this, complicated additional processes are required.

In addition, filling a large amount of excavated empty space with high quality filling soils (A, B, C), such as sand, was a major cause of the increase of the overall construction cost. In particular, if a large pipeline with a diameter of 1.3 [m] or more is to be buried, such as a collecting pipe, the amount of filling soils (A, B, C) used in the deeper and wider excavation of the ground becomes more problematic. Worsened.

In addition, a part of the sand sprayed as the filling soil from the upper side during the burial work penetrates to the lower side of the pipeline 1 as indicated by the arrow T, and generates a soil pressure P, causing the pipeline 1 to be lifted. It was. This is because it is easy to be lifted when sand penetrates into the lower side due to the unstable state of the pipeline 1 because there is almost no load acting on the upper side during buried work. As such, once the pipeline 1 is lifted by sand penetrating downward, the connection between the pipelines 1 is shifted, and the overall buried work of the pipeline 1 is difficult and the working time is delayed.

In addition, it was virtually impossible to fill the secondary sand foundation (part B) in the space immediately below the lower left part and the right part of the pipeline 1. Therefore, not only the lower left part and the right part of the pipeline 1 could not be stably supported, but also the sand of the part was easily lost due to rainwater penetrating into the basement after the completion of the buried work. Because of this, when an empty space is formed in the lower part of the conduit 1, when a strong load is applied from the upper side, the conduit 1 is not easily overcome, and the conduit 1 is easily deformed into a flat shape.

Accordingly, the present invention has been proposed to solve the conventional problems as described above, the object of the present invention is to stably support the pipeline without damage or deformation and to protect the pipeline to secure the overwork safely without filling the filling soil of good quality To provide a housing.

In order to achieve the above object, a pipe protection housing according to the technical concept of the present invention includes: a lower housing that surrounds and supports a lower portion of a pipe line; It is characterized in that it comprises an upper housing coupled to the lower housing in contact with the lower housing while mating with the lower housing and is in contact with the lower housing to distribute the load to the lower housing.

Here, the lower housing may be characterized by having a seating portion formed with a curvature corresponding to the curvature of the conduit to closely wrap the lower portion of the conduit.

In addition, the upper housing may be characterized by having a covering formed with a curvature corresponding to the curvature of the conduit so as to closely wrap the upper portion of the conduit.

In addition, the left portion and the right portion of the lower housing except the center portion are formed of a curved plate body having a curvature corresponding to a conduit, and vertical ribs formed perpendicular to the outer surface of the curved plate body to support the curved plate body may be moved back and forth. It may be characterized by having a plurality along the direction.

In addition, the front end and the rear end of the lower housing is characterized in that the vertical rib is essentially provided, each of these vertical ribs may be characterized in that the fastening hole is formed.

In addition, the upper end of the lower housing and the lower end of the upper housing may be characterized in that the clamping engaging jaw is fastened together by a clamp.

In addition, the lower side surface of the lower housing may be formed in a flat surface, the lower side corner of the lower housing may be characterized in that the supporting projection is further provided.

In addition, the upper housing and the lower housing may be characterized in that it forms a vertically symmetrical shape with respect to each other.

The pipe protection housing according to the present invention as described above, even in the soft ground, such as to remove the soft ground and crushed stone foundation without the cumbersome work to support the lower part of the pipeline to protect the pipeline from damage or deformation.

In addition, the present invention can prevent damage or deformation of the pipeline even against a strong load applied from the upper side by the upper housing to distribute the load to the lower housing while wrapping the upper portion of the pipeline. Therefore, it is possible to stably protect the pipeline even in a section in which strong loads are irregularly applied, such as a railway section and a vehicle traffic section.

In addition, the present invention can safely protect the pipeline without using expensive filling soil, which had to be filled in order to protect the pipeline.

In addition, the present invention, instead of the entire lower housing in the form of a block to bear the load applied to the left portion and the right portion is formed by a curved plate body and can be implemented to reduce the weight of the product by having a vertical rib.

In addition, since the present invention includes a clamping jaw, it is possible to simply and stably couple the lower housing and the upper housing by the clamp.

In addition, the present invention can be stably connected to the lower housing by the fastening hole.

In addition, the present invention has the effect that the ground excavated by the support projections can be easily worked to avoid them even if the rough state by the protrusions, broken stones and gravel.

Hereinafter, embodiments of the present invention as described above will be described in detail with reference to the accompanying drawings.

EXAMPLE

3 is a state diagram used in the present invention.

As shown, the pipeline protection housing according to the present invention stably supports the lower portion of the conduit 1 by the lower housing 10 and the upper housing 20, while completely covering the entire conduit 1 while supporting the load. It is designed to be distributed so that it can safely protect the pipeline (1) even in special sections such as soft ground, railway section, and vehicle passage section, and does not require expensive quality filling soil used for the pipeline (1) protection. Do not.

Hereinafter, the configuration of the pipe protecting housing according to the present invention will be described in detail.

Figure 4 is an exploded perspective view for explaining the configuration of the present invention, Figure 5 is a bottom perspective view of the present invention.

As shown, the present invention consists of a lower housing 10 and an upper housing 20 which are paired with each other to surround the entire conduit.

The lower housing 10 serves to surround and support the lower portion of the conduit. To this end, the lower housing 10 is provided with a seating portion 110 formed of a curvature corresponding to the curvature of the conduit so as to surround and support the lower portion of the conduit. The seating part 110 is formed up to 180 ° of the support angle of the pipe to support the entire lower part of the pipe.

The lower housing 10 is formed in the form of a block to support the load stably in the case of the central portion 121 where the load applied from the upper side is concentrated, and in the case of the left and right portions 123, the curved surface corresponding to the pipe shape. It is provided in the form of a plate. As a result, it is possible to reduce the weight of the entire lower housing 10. Of course, the lower housing 10 as a whole may be configured in a block form, but the disadvantage that the weight of the product is heavy cannot be avoided.

In addition, vertical ribs 130 are provided to support the left and right portions 123 of the lower housing 10. The vertical ribs 130 are formed perpendicularly to the entire outer surface from the left and right portions 123 of the lower housing 10. As a result, the vertical ribs 130 can stably support the left and right portions 123 of the lower housing 10. The plurality of vertical ribs 130 are disposed along the longitudinal direction of the lower housing 10. A fastening hole 131 is formed in the vertical rib 130 provided at the front end portion and the rear end portion thereof. The fastening hole 131 allows a simple fastening of the lower housing 10 of the present invention in a row by simply using fastening members such as bolts and nuts.

In addition, the lower locking jaw 125 for clamping is formed to protrude outward from the upper left and right sides of the lower housing 10. The lower locking jaw 125 is provided to correspond to the upper locking jaw 225 formed at the lower end of the upper housing 20. As a result, the lower housing 10 and the upper housing 20 may be bundled into one by simply clamping using the clamp 150 in an adjacent state facing the lower locking jaw 125 and the upper locking jaw 225.

In addition, the lower surface 127 of the lower housing 10 is formed in a flat shape, and a support protrusion 140 is provided at the corner of the lower surface 127 of the lower housing 10. The support protrusion 140 serves to minimize the area in contact with the bottom of the excavated ground to easily avoid coarse foreign materials such as broken stones or gravel. If the entire lower side 127 of the lower housing 10 is in contact with the bottom of the excavated ground without the support protrusion 140, it is difficult to avoid foreign substances such as broken stones or gravel, which may cause a problem of lifting during installation. Can be.

The upper housing 20 is paired with the lower housing 10 serves to cover the upper portion of the conduit. To this end, the upper housing 20 has a covering portion 210 that can cover and cover the upper portion of the pipeline in close contact. The covering portion 210 has a curvature corresponding to the curvature of the pipe.

In addition, the upper housing 20 is made of a curved body 220 in the form of a curved plate body that is generally matched with the upper portion of the outer surface 221 is also made of a curved surface. The upper and lower locking jaws 225 paired with the lower locking jaws 125 of the lower housing 10 are formed to protrude outward from the left and right lower ends of the body 220 having the curved plate body shape. do. If the upper housing 20 is provided to cover the upper portion of the pipeline as described above, the stepped work for filling the filling soil and the filling soil, which has been used for filling the surrounding space, is no longer necessary.

However, the most important role of the upper housing 20 is to distribute the load applied from the upper side to the lower housing 10 to protect the pipeline from excessive load. To this end, the lower ends located on the left and right sides of the upper housing 20 are configured to be supported in contact with the upper ends located on the left and right sides of the lower housing 10. As a result, the load applied from the upper side can be evenly distributed in the conduit and the lower housing 10. As described above, the present invention is able to protect the pipeline without damage or deformation even in special sections to which irregular and strong loads are applied, such as railway sections and vehicle passage sections, by a combination of the lower housing and the upper housing that distribute the load concentrated in the pipeline. do.

6 is a reference view for explaining the assembly with the pipeline using the present invention.

As shown, the lower housing 10 and the upper housing 20 according to the present invention can be assembled simply by assembling the conduit 1 in a state of being wrapped.

In this case, in order to make the pipe assembly, the pipe line 1 to be buried in units of a predetermined section is connected to each other, and several lower housings 10 are prepared and arranged in line. At this time, if the bolt and nut 133 is installed through the fastening hole 131, the lower housing 10 may be stably connected.

Thereafter, the pipe 1 connected to the seating part 110 of the lower housing 10 is placed and rested thereon.

Then, the upper housing 20 to the upper portion of the conduit (1) while being placed in sequence. Then, the upper housing 20 covers the upper portion of the conduit 1 and the lower ends positioned on the left and right sides thereof are supported in contact with the upper ends positioned on the left and right sides of the lower housing 10.

Subsequently, when the lower locking jaw 125 of the adjacent lower housing 10 and the upper locking jaw 225 of the upper housing 20 are clamped together by using the “c” shaped clamp 150, the lower housing 10 may be clamped together. ) And the upper housing 20 is fastened in a state in which the pipeline 1 is wrapped to complete the assembly of the pipeline assembly. When the pipeline assembly is prepared by such a simple assembly work, it is only necessary to bury it underground.

In order to bury the pipeline assembly, it is preferable to excavate the ground for embedding with equipment such as an excavator before the pipeline assembly is made to dig. Then remove the broken stones or gravel from the excavated ground and smooth the floor.

The pipeline assembly is then laid down on a flat, trimmed ground floor. At this time, since the support protrusion 140 provided on the lower side surface 127 of the lower housing 10 contacts only a part of the bottom of the excavated ground, such as broken stones or gravel that may still remain on the bottom of the excavated ground. Foreign objects can be easily avoided. Therefore, the pipeline assembly is rarely lifted up or disturbed by foreign matter such as broken stones or gravel. If the support protrusion 140 is placed on a foreign object such as a broken stone or gravel that may remain on the ground where the ground is excavated, and the pipeline assembly is lifted up or is not aligned properly, it is only necessary to correct the position by moving the corresponding part slightly. Problems you face can be easily solved.

If the pipeline assembly is placed directly on the ruptured ground, the laying process is completed when the original coarse soil generated during the excavation work is filled without having to provide a separate high quality filling soil.

7 is an exploded perspective view for explaining the configuration of the present invention according to a modified embodiment.

As shown, according to the modified embodiment of the present invention, instead of having a separate upper housing 20 having a different shape from the lower housing 10, the lower housing 10 is turned upside down to be used as the upper housing 20. It is characterized by.

According to this configuration there is an advantage that does not need to operate a separate production line from the lower housing 10 in order to provide the upper housing (20). But in its function, it is no different from before.

Such a modified embodiment may have various forms of the outer side as long as the upper housing 20 can deform the upper part of the conduit and distribute the applied load to the lower housing 10 before deformation. It is to show.

Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.
