technical field

The present invention relates to a method of laying utility-pipe conduits, and more particularly, to a method of laying utility-pipe conduits more easily and safely in a shorter period of time.

Background technique

The integrated pipe line is an underground tunnel through which various integrated pipes, such as water supply and drainage pipes, various cables, and gas supply pipes, are laid and passed. Since such integrated pipes can be installed underground by means of integrated pipe lines, road structures and traffic conditions can be improved.

The pipes or pipes are installed in the piping system used to accommodate the piping such as water supply and drainage pipes, various electrical cables, and gas supply pipes. To this end, steel structures known as pipe racks are installed in integrated pipe runs to support these pipes and pipes.

The traditional method of installing integrated pipelines is carried out as follows: excavating the ground; forming the bottom and side walls of the integrated pipeline in the excavated ground; installing support structures on the bottom and side walls of the integrated pipeline; The structure forms slabs on the side walls; removes support structures; and installs pipe racks in integrated pipe runs.

During excavation operations, the ground is excavated to create a trench for the manifold piping. Depending on ground conditions and other conditions, excavation operations may be carried out by various methods. For example, the ground may be excavated after the piles have been installed vertically in the ground and the reinforcing structure installed. Also, it is possible to excavate the ground without using reinforcement structures.

Referring to FIG. 1 , after the excavation operation, the bottom wall 10 and the side wall 20 of the integrated pipeline 100 are formed in the excavated ground. The integrated pipe line 100 is usually made of reinforced concrete, as are the bottom wall 10 and the side walls 20 . The bottom wall 10 and the side walls 20 may be formed by a known method of constructing a reinforced concrete structure: making a concrete form; arranging reinforcing rods in the concrete form; pouring concrete into the concrete form and curing.

FIG. 2 shows the ply 30 formed on the side wall 20 using the support structure 40 . The support structure 40 comprises a plurality of steel rods connected together. The external thread is formed on one end of the steel rod, and the internal thread is formed on the other end of the steel rod, so that a desired length can be obtained by connecting the steel rods. After the steel rods are connected to obtain a desired length, the steel rods are arranged in an upright position at predetermined intervals. Next, a concrete form is formed on the steel rods, and the slab 30 is formed by pouring concrete onto the form.

Referring to FIG. 3 , after the slab 30 is formed, the support structure 40 is removed, and the pipe frame 50 is installed in the integrated pipe line 100 . As noted above, the pipe frame 50 is a steel structure, and the pipe frame 50 is typically formed as an H or I beam. Pipes 55 are laid on the pipe frame 50 to accommodate integrated pipes such as water supply and drainage pipes, various cables, and gas supply pipes.

However, the conventional method of laying composite pipelines has limitations due to the fact that the steel rods for supporting the structure 40 are repeatedly used at various construction sites, so the strength of the steel rods may decrease, and the steel rods The rod has a larger slenderness ratio. Therefore, the possibility of bending the steel rod increases. If the steel rods of the support structure 40 are bent due to the weight of the slab 30, workers may be injured and the integrated pipe line 100 cannot be laid on time.

Also, since the pipe frame 50 is installed in the integrated pipe line 100 after the plate layer 30 is formed, a part of the plate layer 30 is not formed so as to be used as a material inlet, thereby forming the pipe frame 50 in the integrated pipe line 100 , it is easy to transport the material of the H-beam into the integrated pipe line 100 . Next, after the pipe frame 50 is completely formed in the integrated pipe line 100, the part of the plate layer 30 is formed. Since the material of the H-beam is transported to the desired position in the integrated pipe line 100 through the material inlet and then assembled in the integrated pipe line 100, it takes a long time to form the pipe frame 50. Furthermore, since the integrated pipe line 100 is closed, it is dangerous to perform welding when forming the pipe frame 50 in the integrated pipe line 100 .

Detailed ways

The method of laying a manifold pipeline will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

FIG. 1 shows the bottom wall 10 and side walls 20 of an integrated pipeline 100 formed in a trench dug in the ground.

FIG. 3 shows the pipe manifold 100 of FIG. 2 as the pipe rack 50 is formed after removal of the support structure.

FIG. 4 shows the integrated pipe line 100 of FIG. 1 when the pipe rack 50 is formed on the bottom wall 10 and the side wall 20 .

FIG. 5 shows the integrated pipe pipeline 100 of FIG. 4 when the cover plate 60 is formed on the pipe frame 50 according to an embodiment of the present invention.

According to the present invention, the method of laying the integrated pipeline 100 includes: excavating the ground; forming the bottom wall 10 and the side wall 20; installing the pipe rack 50; forming the slab; and connecting the pipe 55 during the concrete drying of the slab.

During excavation operations, the ground is excavated to form a trench for the manifold conduit 100 . Since this excavation operation is the same as that of the conventional method of laying integrated pipelines, a detailed description of the excavation operation will be omitted.

During the operation of forming the bottom wall 10 and the side wall 20 , as shown in FIG. 1 , the bottom wall 10 and the side wall 20 of the integrated pipe piping 100 are formed using reinforced concrete. As described above, the bottom wall 10 and the side wall 20 may be formed by: making a concrete form; arranging reinforcing rods in the concrete form; pouring concrete into the concrete form and curing.

During the operation of installing the pipe rack 50 , the pipe rack 50 preformed in a factory is installed in the bottom wall 10 between the side walls 20 . Since the integrated pipe line 100 may have a length ranging from several hundred meters to several thousand meters, the pipe frame 50 having a length corresponding to the length of the integrated pipe line 100 cannot be manufactured in a factory. Therefore, a sub-pipe rack having a predetermined length is manufactured in a factory, and then the sub-pipe rack is transported to the construction site of the integrated pipe line 100 and installed in the integrated pipe line 100 using a crane. Afterwards, the sub-pipe racks are assembled into a pipe rack 50 . If the sub-pipe frame is manufactured in a factory, the pipe 55 and the insulating cable duct can be formed together with the sub-pipe frame in the form of an assembly. Because the pipe rack 50 is installed in the pipe manifold 100 before a ply (not shown) is formed thereon, there are many advantages in installing the pipe rack 50 . For example, the pipe rack 50 can be easily installed at a desired location in the pipe manifold 100 because the top of the pipe manifold 100 is not covered by the ply. In the traditional method of forming integrated pipe runs, when forming the plies of integrated pipe runs, a part of the ply is not formed so as to be used as a material inlet, and the material for pipe racks is delivered to the integrated pipe through this material inlet. pipe run before moving it to the desired location in the pipe run. However, according to the current embodiment of the present invention, since the top of the integrated pipe piping 100 is not covered by the ply, the materials for the pipe rack 50 can be easily delivered to the integrated pipe piping 100 compared with the conventional method. at the desired location in .

Moreover, since the sub-pipe racks are prefabricated in the factory, by transporting the sub-pipe racks to desired positions in the integrated pipe line 100 and connecting the sub-pipe racks in the integrated pipe line 100, it is possible to easily A pipe rack 50 is formed. Therefore, the time required to manufacture the pipe rack 50 at the construction site can be saved.

Furthermore, the sub-pipe racks are connected to each other in an open space, for example by welding. Therefore, the possibility of accidents can be reduced.

After the installation of the pipe rack 50 has been completed, the slab 30 ( FIG. 3 ) is formed as the upper structure of the integrated pipe line 100 , and the slab is formed using the pipe rack 50 as a supporting structure without using additional supporting structure.

A prefabricated cover plate 60 is placed over the side walls 20 and the tube frame 50 . Next, reinforcing rods are arranged on the cover slab 60, and concrete is poured on the cover slab 60 to form a slab.

The cover plate 60 has a reinforced concrete structure comprising a rectangular concrete body and reinforcing rods arranged in the rectangular concrete body. Protrusion structures 61 are formed on the top surface of the cover plate 60 so as to be covered with concrete poured onto the cover plate 60 to form a slab. In the current embodiment, the protruding structure 61 includes rods and wires. The rods are spaced apart from the top surface of the cover plate 60 and arranged along the length direction of the cover plate 60 . Steel wires are anchored into the cover plate 60 to support the rods spaced from the top surface of the cover plate 60 .

The cover plate 60 is prefabricated by prefabrication in a separate workshop using a prefabrication process. In this case, since the facilities of the workshop can be effectively utilized, the cover plate 60 can be manufactured under optimized conditions. Therefore, the cover plate 60 can have precise dimensions and higher strength than a cover plate formed at a construction site.

The cover plate 60 formed by prefabrication is transported to the construction site of the integrated pipeline 100 and placed on the side wall 20 and the pipe frame 50 . Next, the reinforcing rods of the protruding structures 61 are arranged on the cover plate 60 and concrete is poured on the cover plate 60 to form a slab on the integrated pipe line 100 .

When the deck 60 prefabricated as described above is used to form the slab, no lower concrete form is required to form the slab. Therefore, time, manpower, and equipment required for forming the lower concrete form and removing the lower concrete form after forming the slab can be saved. Also, since the cover plate 60 is prefabricated and delivered to the construction site of the integrated pipe piping 100, the slabs can be formed in a simple manner.

If the cover plate 60 is placed on the integrated pipe piping 100 in such a manner that both edges of the cover plate 60 are respectively arranged on the side wall 20, the cover plate 60 may be damaged or broken by its weight and the concrete poured onto the cover plate 60. . However, since the pipe frame 50 supports the cover plate 60, the cover plate 60 can be safely and properly formed. Also, the cover plate 60 may have the same height as the side wall 20 .

After concrete is poured on the cover plate 60 to form a slab, the pipes 55 laid on the pipe frame 50 are connected while the poured concrete is curing. Within a predetermined time after concrete is poured onto the cover plate 60, the concrete cures to a sufficient strength for performing the connecting operation of the pipe 55. Referring to FIG. Therefore, the pipes 55 can be connected before the concrete is fully cured, thereby reducing the time required to form the integrated pipe line 100 . Figure 3 shows the pipe rack 50 installed after the plies have been formed.

In the above embodiments, the sub-pipe racks are prefabricated in the factory, and assembled into the pipe rack 50 at the construction site of the integrated pipeline 100 . However, the pipe rack 50 can be formed at the construction site without the use of prefabricated sub-pipe racks, if desired.

Also, in the above-described embodiment, the ply is formed using the prefabricated cover plate 60 . However, instead of using the cover slab 60, if desired, a lower concrete form could be used to form the slab, which could then be removed after the slab has been formed.

As described above, the present invention provides the following advantages.

Since no additional support structure is used to form the slab, the multi-pipeline can be laid in a shorter time and the possibility of accidents can be reduced.

Also, since the pipe racks are installed before the plies are formed, it is possible to install the pipe racks in open spaces. Therefore, the material for the pipe rack can be transported and assembled more easily and safely.

Furthermore, if the pipe rack is formed using sub-pipe racks prefabricated in a separate factory, the integrated pipe line can be laid more quickly than in the case of forming the pipe rack at the construction site of the integrated pipe line. Also, if the deck is used to form the slab, time, manpower, and equipment can be saved since there is no need to prepare the lower concrete form to form the slab and remove the lower concrete form after the slab is formed.

While the invention has been particularly shown and described with reference to exemplary embodiments of the invention, it will be understood by those skilled in the art that modifications may be made to the invention without departing from the spirit and scope of the invention as defined by the appended claims. Various changes in form and detail.
