Description

[0001]
[Industrial applications]
The present invention relates to facilities coating method of the pipe laying for the train Chi to be embedded into the underground.
[0002]
[Prior art]
Usually, a trench for laying a pipe is constructed according to a procedure as shown in FIGS.
[0003]
First, as shown in FIG. 5, the ground is excavated and the floor is laid, the base 40 and the formwork 44 of the side wall 42 are assembled, and concrete C is poured.
[0004]
Next, when the concrete C of the base 40 and the side walls 42 is cured and cured, the form 44 is removed, and as shown in FIG. 6, a support for supporting the bottom plate 48 is constructed with the pipe support 54, and the form 52 of the slab 50 is formed. And concrete C is cast.
[0005]
Next, when the concrete C is cured and cured, the pipe support 54, the bottom plate 48, and the formwork 52 are removed to complete a box-shaped trench 56 as shown in FIG. Here, as shown in FIG. 8, a rack is formed by the pipe support members 58 inside the trench 56, and the pipes 60 are laid on the pipe support members 58.
[0006]
However, the work of constructing and removing the shoring with the pipe support 54 is troublesome, and it is not easy to shorten the construction period. Also, the work of assembling a rack for supporting the pipes 60 with the pipe support members 58 is troublesome.
[0007]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-described circumstances, and has as its object to improve the efficiency and labor-saving of trench construction and pipe laying work, and to shorten the construction period of piping work.
[0008]
[Means for Solving the Problems]
[0009]
The method of constructing a pipe laying trench according to claim 1 , wherein a pipe is laid in a pipe laying unit provided on a side wall of the lower trench whose upper side is open, and the lower trench in which the pipe is laid is suspended. Installing the pipe on a suspension member disposed on a ceiling wall of an upper trench which is joined to cover an opening of the lower trench and forms a piping installation space; and And joining the lower trench with the lower trench.
[0010]
[Action]
[0013]
The construction method of a pipe laying trench according to claim 1, firstly, the pipe to the pipe laying for units provided in the side wall of the lower trench is laid. By suspending the lower trench in which the pipe is laid and installing it on the base, the work of laying the pipe in the trench can be omitted.
[0014]
Next, a pipe is laid on the suspension member provided on the ceiling wall of the upper trench, and the pipe is suspended and joined to the lower trench. Thus, the piping installation trench is completed, and after completion, there is no need to install piping, and the installation work is completed only by connecting the piping installed for each block.
[0015]
【Example】
As shown in FIG. 1, a U-shaped lower trench 12 constituting a trench 10 according to the present embodiment is installed on a floored base 14. A joint tenon 16 is formed in the opening above the lower trench 12 as a joining means.
[0016]
Further, a ladder-shaped rack 18 is integrally attached to the side wall of the lower trench 12, and the pipes 20 are laid in advance in a multilayered manner. The lower trench 12 is hung by a not-shown clay or the like and is set on a base 14.
[0017]
As shown in FIG. 3, the upper trench 22 that covers the opening of the lower trench 12 has a U-shape that opens downward, and a joint tenon 24 that engages with the joint tenon 16 is formed in the opening.
[0018]
A suspension member 26 hangs down from the ceiling wall of the lower trench 12 so that the pipe 20 can be held by a holder 26A formed at the tip thereof.
[0019]
Next, a construction method for laying a pipe using the trench 10 according to the present embodiment will be described.
[0020]
As shown in FIGS. 1 and 2, first, necessary pipes 20 are laid on the rack 18 of the lower trench 12 on the ground. Next, the lower trench 12 is suspended and installed on a base.
[0021]
Here, as shown in FIGS. 3 and 4, the pipe 20 is laid on the suspension member 26 of the upper trench 22, and the joint tenons 16 and 24 are joined together so as to cover the opening of the lower trench 12, and the pipe is laid. Make up the space.
[0022]
For this reason, there is no need to assemble the pipe support member in the trench 10 and lay the pipe 20. Also, the laying work is completed only by connecting the pipes 20 installed for each block.
[0023]
In this embodiment, the method of forming one block of the trench 10 has been described. However, the steps as described above are sequentially repeated to extend the span, or the lower trench 12 is installed several blocks first. The upper trench 22 may be placed.
[0024]
Each block of the trench 10 is connected to each other by inserting a PC steel material into a sheath hole penetrated through the trench 10 and fastening both ends of the PC steel material by a nut and an anchor plate in units of several blocks. Are pressed against each other to connect the joint portions.
[0025]
【The invention's effect】
Since the present invention is configured as described above, the efficiency of construction of the trench and the work of laying the piping and labor saving can be achieved, and the construction period of the piping work can be shortened.
