Description

PIPE STAND WITH FILL-SOIL PREVENTION WALLS}

The present invention relates to the laying of pipelines for laying pipelines underground, providing a separate isolated filling space to fill the filling soil by a pair of protective walls blocking the left and right sides of the pipeline, to protect the pipeline during the laying operation The present invention relates to a pipeline pedestal having a fill soil protection wall suitable for dramatically reducing the amount of expensive fill soil to be filled for the purpose.

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.

In this case, the laying work should be done with great care. If the foundation hole is poor, not only the sedimentation of the pipeline may cause congestion, decay and odor of sewage, but also in the worst case, the pipeline may be broken and leak. This is because the groundwater may invade and the soil around the pipeline flows in and the roads may sink.

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) while filling the pipeline (1). At this time, the type of filling soil (A, B, C) and the filling method should be implemented by applying the sewage facility standard prescribed in consideration of the type and soil quality of the pipeline (1). 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, the filling cost of high quality filling soil (A, B, C), such as sand in most of the large space excavated and vacant, so that the overall construction cost is increased It was a major cause.

In particular, if a large pipeline with a diameter of 1.3 [m] or more must be buried, such as a collecting pipe, the amount of filling soils (A, B, C) used in relation to the excavation of the ground is deeper and wider. Was even worse.

In addition, the part of the sand sprayed as the filling soil from the upper side during the buried operation is penetrated to the lower side of the pipeline 1 as indicated by the arrow (T) to generate a soil pressure (P-1) to cause the pipeline 1 to be lifted up Caused. This is because it is easy to lift when sand penetrates downward because the state of the pipe 1 is unstable because there is almost no load acting on the upper side during the 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.

In addition, in the soft ground, as some sections of the pipeline 1 are settled, foreign substances flowing in the pipeline 1 with sewage gradually accumulate, resulting in a fatal result in that the flow path is reduced and the sewage flow 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.

Accordingly, the present invention has been proposed to solve the conventional problems as described above, an object of the present invention is to provide an isolated filling space to reduce the amount of filling soil to be filled for the protection of the pipeline during laying of the pipeline It is to provide a pipeline stand having a soil protection wall.

In order to achieve the above object, the pipeline base having a fill soil protection wall according to the technical idea of the present invention, the main body for supporting the pipeline from the lower side; It is constructed on the left and right sides of the main body, respectively, and includes a pair of protection walls to block the left and right of the pipeline, so that the filling soil for the protection of the pipeline between the pair of protection walls of the technical configuration features It is done.

Here, the protective wall may be characterized in that it has a height exceeding the height of the supported pipe.

In addition, it may be characterized by further comprising a plurality of vertical ribs formed along the main body from the outer surface of the protective wall.

In addition, the main body may be provided with a seating portion that closely adheres to the lower portion of the pipeline, and has a free space to collect and accommodate the filling soil penetrating into the gap between the seating portion and the pipeline.

In addition, a plurality of partitions erected by connecting the left side wall and the right side wall in the free space may be characterized by supporting the lower central portion of the conduit together with the front and rear walls.

In addition, the seating portion may be characterized in that it is formed with a curvature corresponding to the curvature of the pipeline so as to surround the lower portion of the pipeline.

In addition, the lower side surface of the base is formed in a flat surface, the lower side corner of the base may be characterized in that it further provided with a supporting projection installed in a protruding form, respectively.

The pipeline stand having the fill soil protection wall according to the present invention having the technical features as described above should be filled for the protection of the pipe during laying work by providing a filling space separated by a pair of protection walls that block the left and right sides of the pipeline. There is an effect that can significantly reduce the use of expensive filling soil.

In addition, the present invention collects all the filling soil causing the earth pressure by penetrating from the upper side to the lower side of the pipeline by the configuration to form a clearance space that the pipeline is lifted up or disturbed by the filling soil penetrating to the lower side of the pipeline during buried work Problems can be contained at source.

In addition, the present invention is safe against earth pressure generated in the lower ground of the pipeline by the configuration that completely blocks between the ground excavated by the base and the lower portion of the pipeline.

In addition, the present invention can completely prevent the damage to the pipeline by the rough ground and the broken stone and gravel, etc. of the excavated ground because it completely blocks between the excavated ground and the lower portion of the pipeline.

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

EXAMPLE

Figure 3 is a perspective view for explaining the present invention, Figure 4 is a reference cross-sectional view according to A1-A2 of Figure 3, Figure 5 is a plan view of the present invention, Figure 6 is a bottom perspective view of the present invention.

As shown, the present invention provides an isolated filling space S1 (see FIG. 4) that fills the filled soil by a pair of protective walls 170 that completely block the left and right sides of the conduit 1. The present invention can significantly reduce the amount of expensive filling soil such as sand used for protecting the conduit 1 by providing a separate limited filling space (S1). This can drastically reduce the excessive construction costs that may occur due to the use of filled soils.

Hereinafter, the configuration of the pipeline pedestal provided with the filling soil protection wall according to the present invention will be described in detail for each component.

The present invention is the base 110 forming the main body, the front and rear walls 120, the left and right walls 130, a plurality of partitions 140, support protrusions 150, extended support member 160 And a pair of protective walls 170 and vertical ribs 180 forming the separate filling space S1.

First, the protective wall 170 is vertically connected with the upper end of the extended support member 160. At this time, the protective wall 170 is erected to a height exceeding the height of the pipe (1) supported by the seating portion (120A, 160A) formed by the upper surface and the inner surface of the extended support member of the front and rear walls 120. The excess height will vary depending on the size of the conduit 1, but if it is about 5 [cm] can be completely covered with the filling soil to the top of the conduit is suitable.

When a pair of protective walls 170 are provided in this way, it is possible to provide a separate isolated filling space S1 for filling the filling soil therebetween. As a result, it is not necessary to fill the entire excavated site with expensive filling soil used to prevent damage to the pipeline 1 during the laying of the pipeline 1. Instead, it only needs to be filled in the small filling space S1 formed between the pair of protective walls 170. And the remaining excavated site is to fill the original rough soil generated during the excavation. Therefore, it is possible to drastically reduce the amount of filling soil used as expensive high quality soil, such as sand, while the soil generated during excavation remains only a little easier to handle.

The main body has a base 110, a front wall and a rear wall 120, a left wall and a right wall 130, a plurality of partitions 140, a plurality of supporting protrusions 150 forming a bottom surface as described above And an extension support member 160. Among them, the base 110, the front wall and the rear wall 120, the left wall and the right wall 130 to collect and receive some filled soil penetrating between the seating portion (120A, 160A) and the conduit (1) The clearance S2 is formed. Hereinafter, each of the components constituting the main body will be described.

The base 110 serves to block and block the bottom of the excavated ground and the lower portion of the conduit 1 while forming the bottom surface of the free space S2. To this end, the base 110 is formed of a rectangular flat member having a long front and rear length formed in the longitudinal direction of the conduit 1 compared to the left and right widths. At this time, the base 110 is made without a portion cut or opened except for the drain 111 formed into a small through hole. Here, the drain hole 111 is provided between them considering the partition wall 140, and serves to drain the water penetrating from the upper side to the lower side as well as to neutralize the influence of buoyancy when the water fills the basement. . However, since the drain hole 111 is formed in a sufficiently small size, the ground excavated by earth pressure does not penetrate into the free space S2 while partially protruding. In addition, the lower side of the base 110 is formed in a plane. This makes it easy to lay down and work on a flat, polished excavation surface.

The front wall and the rear wall 120 are respectively erected before and after the base 110, the upper surface is formed with a seating portion (120A) for tightly supporting the lower portion of the conduit (1). At this time, the seating portion (120A) of the front wall and the rear wall 120 is formed in a curve having a curvature corresponding to the curvature of the conduit (1).

The left side wall and the right side wall 130 are erected on the left and right sides of the base 110, respectively, and connect ends of the front side wall and the rear side wall 120, respectively. As a result, the base 110, the front wall, and the rear wall 120 together with the free space (S2) for collecting the entire portion of the filling soil penetrating to the lower side of the pipeline (1) is formed.

The partition wall 140 is connected to the left side wall and the right side wall 130 in the clearance S2 and is erected at the same height while being in parallel with the front side wall and the rear side wall 120. The upper surface 140A of the partition wall 140 is curved to have a curvature corresponding to the curvature of the conduit 1, like the seating portion 120A. As a result, the partition wall 140 may cooperate with the front wall and the rear wall 120 to support the pipeline 1. At this time, the partition wall 140 is provided with a larger number as the distance between the front wall and the rear wall 120 is wider to serve to prevent the pipe 1 from hitting the intermediate points. In addition, the partition wall 140 also serves to reinforce rigidity by tying the base 110, the front wall and the rear wall 120, the left wall and the right wall 130 structurally together.

The supporting protrusions 150 may be provided at lower corners of the base 110, respectively, and may be provided in the middle of the base 110 according to the length and width of the base 110. Such support protrusion 150 minimizes 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 of the base 110 without the support protrusion 150 is in contact with the bottom of the excavated ground, it is difficult to avoid foreign substances such as broken stones or gravel, so that the pipeline stand and the pipe line 1 of the present invention are lifted up. However, the connection between the pipes (1) is a deadly result that is shifted.

The extended support member 160 is formed to extend from the upper end of the left and right walls 130, respectively, the left side and the right side of the lower portion of the conduit 1 by the mounting portion 160A formed on the inner side Wrap it around and support it. The seating portion 160A of the extended support member 160 is formed in a curved surface having the same curvature as the conduit 1 so as to surround and support the conduit 1.

Here, the seating portion 160A of the extended support member 160 forms the entire seating portion 120A and 160A together with the seating portion 120A formed on the upper surface of the front side wall and the rear side wall 120. At this time, the seating portion 120A of the front wall and the rear wall 120 supports the lower portion of the conduit 1, but the support angle (G1, see Fig. 4) relative to the center of the conduit 1 90 ° or more 180 It is preferably to be supported to a range of less than °, and the seating portion (160A) of the extended support member 160 is to be supported by up to 180 ° support angle (G2, see Figure 4) starting thereafter. Then, the seating portion 120A of the front wall and the rear wall supports the lower central portion of the pipeline 1 to stably support the load acting on the pipeline 1, and the seating of the extension support member 160. The part 160A is in charge of the lower left part and the right part of the pipe line 1, which was substantially impossible to chop even when filling the filling soil, thereby stably supporting it.

When the extension support member 160 is provided in this way, the volume of the entire product can be reduced based on the same area supporting the lower portion of the pipeline 1, and the area of the base 110 in contact with the excavated ground becomes unnecessary. Can be prevented.

The vertical ribs 180 are formed vertically along the outer side of the extended support member 160 and the left and right walls 130 starting from the outer surface of the protective wall 170. When 160 is loaded, it serves to stably support them. In particular, since the protective wall 170 is easy to be vulnerable to the load in the horizontal direction when the filling soil is filled in the filling space (S1), the role of the vertical rib 180 to withstand this is important. The vertical ribs 180 are disposed in plural along the front and rear directions, and fastening holes 171 are formed in the vertical ribs 180 provided at the front and rear ends. The fastening hole 171 simply connects the pipeline pedestal of the present invention by using fastening members such as bolts and nuts.

Referring to Figures 7 to 9 and the other drawings attached to the process of embedding the pipeline 1 to be carried out using the pipeline pedestal having a fill soil protection wall according to the present invention configured as follows. 7 to 9 are a series of reference diagrams for explaining the embedding work of a pipeline implemented using the present invention.

First, the ground for embedding the pipeline 1 is excavated with equipment such as an excavator to destroy. Then remove the broken stones or gravel from the excavated ground and smooth the floor.

Subsequently, a plurality of pipeline pedestals according to the present invention are laid down on the bottom of the flattened excavated ground and aligned in line. At this time, since the support protrusion 150 provided on the lower side of the base 110 contacts only a part of the ground of the excavated ground, foreign substances such as broken stones or gravel, which may still remain on the ground of the excavated ground, are easily avoided. can do. Therefore, the pipeline pedestal of the present invention is hardly lifted up or disturbed by foreign matter such as broken stones or gravel. If the support protrusion 150 is placed on a foreign object such as a broken stone or gravel that may remain on the ground where the ground is excavated, the pipeline pedestal of the present invention is lifted or misaligned. One problem can be easily solved.

Subsequently, when the pipeline 1 is placed on the pedestal of the present invention from the upper side, the lower central portion, the left portion and the right portion of the pipeline 1 are stably supported by the seating portions 120A and 160A. As a result, even after the soil is filled and a strong load is applied from the upper side, the base 110 can stably support the load of the pipeline 1, and the base 110 completely blocks between the lower portion of the pipeline 1 and the ground of the excavated ground, so that the earth pressure It is possible to prevent the pipeline 1 from being damaged due to the impact of the broken stones and gravel remaining in the excavated ground.

Subsequently, the filling soil T1 is filled in the filling space S1 formed between the pair of protective walls 170 as shown in FIG. 8. Then, the filling soil T1 covers the upper portion of the conduit 1 in the filling space S1, the upper portion of the conduit 1 is the filling soil T1, and the lower central portion of the conduit 1 is the front wall and The seating portion 120A of the rear wall 120 and the upper surface 140A of the partition wall 140 are supported by the seating portion 160A of the extended support member 160 while the lower left portion and the right portion of the pipeline 1 are supported. The enveloping form can safely protect the pipeline from debris.

In this process, even if some of the marked filling soil T1 penetrates between the seating portions 120A and 160A and the conduit 1, it is collected in a large free space S2 and thus does not have any influence on the conduit 1. do. Therefore, the problem which caused some filling soil T1 to penetrate below the pipeline 1 and raises the pipeline 1 while causing earth pressure does not arise.

Then, the remaining space of the excavated portion as shown in Figure 9 is filled with the original rough soil (T2) generated during the excavation work. Then, the buried work of the pipeline 1 is completed.

As described above, the pipeline pedestal according to the present invention only needs to fill the filling soil T1 in the filling space S1 to a small size formed by the protective wall 170. Therefore, the amount of expensive filling soil can be drastically reduced. In addition, the base 110 is completely blocked between the lower part of the conduit 1 and the bottom of the excavated ground to prevent damage to the conduit 1 due to contact with the bottom of the rough excavated ground, broken stone or gravel. Of course, it is possible to fundamentally block the lifting phenomenon or the displacement problem of the pipeline (1) that can be caused by some filling soil (T1) penetrating to the lower side of the pipeline 1 by the free space (S2).

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.
