Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of piping each section having a predetermined interval as one section.

When piping a section with a predetermined interval, such as connecting each manhole with a drain pipe, if the piping is done using only a fixed length pipe with a pipe holder □ at one end, the fixed length pipe will connect at the end. This results in gaps that cannot be achieved.

In this case, the length is adjusted by cutting the pipe to a fixed length.
The remaining cut pipe is a straight pipe without a pipe holder □, so it cannot be used and is thrown away, which is uneconomical. This invention was made in an attempt to eliminate the above-mentioned drawbacks, and the gist of the invention is to provide a pipe holder □ at one end for each section with a predetermined interval as one section.
When connecting and piping sequentially fixed length pipes equipped with
Cut a separately prepared auxiliary pipe having pipe ports at both ends to make one pipe of a predetermined length, pipe the first section with the pipe cut to the predetermined length and the fixed length pipe, and The other side of the auxiliary pipe is used for piping another section, and the second section is piped using the pipe, the fixed-length pipe, and the pipe cut to a predetermined length from another auxiliary pipe, and the following is done. The piping method consists in piping each section by repeating the same procedure in sequence.

Next, the piping method of this invention will be explained with reference to embodiments shown in the drawings.

la, lb, lc are manholes arranged at predetermined positions, and a tube receiver □ part 21 is provided on one side wall of each manhole la, lb, lc to serve as an inlet, and a tube insertion port is provided on the other side. A portion 22 is provided to serve as an outlet.

Reference numeral 3 denotes a fixed-length tube having a tube socket 31 at one end, and is made of, for example, a hard vinyl chloride tube.

4 has tube sockets 41 on both ends similar to the pipe sockets 31 of the standard length tube.
, 41 is an auxiliary pipe made of hard vinyl chloride pipe.

It is preferable that the auxiliary tube 4 has the same length as the fixed length tube 3, but it may be longer than the fixed length tube 3. Incidentally, it is also possible to form a tube receiver □ and use it as an auxiliary pipe by widening the straight section of the regular length tube 3 in the same way as the tube receiver □ 31 at the other end. The tube holders □ of the fixed-length tube 3 and the auxiliary tube 4 may be a so-called rubber ring holder □ fitted with a rubber ring, as shown in the tube holder 41 of the auxiliary tube 4 shown in the figure, or may be an adhesive type holder □. First, manholes la and lb
In this case, the straight pipe of the standard length pipe 3 is inserted and connected to the pipe socket □ part 21 which is the inlet of the manhole la, and the next specified pipe is connected to the pipe socket 31 of the standard length pipe 3. Insert and connect the straight tube part of the talon tube 3.

When connecting the fixed length pipes 3 one after another, the fixed length pipe 3 cannot be connected to the insertion port 22 of the manhole lb. The interval 1 is shorter than the fixed length pipe 3.
remains. Therefore, the auxiliary pipe 4 is cut from one end to a length corresponding to the distance 1. This part 4a has a tube socket □41 at one end and a straight pipe at the other end, so connect the pipe section to the pipe socket 31 at the end of the regular length pipe 3, and connect the pipe socket □41 at the other end to the manhole lb. Insert and connect to the insertion port 22. Thus manholes la and lb
A plurality of fixed length pipes 3 and an auxiliary pipe 4 cut into a predetermined length 1 are used to provide piping between the pipes. Incidentally, if the distance 1 is known in advance, the auxiliary pipe 4a cut to a predetermined length 1
It is also possible to connect the fixed length tubes 3 in the middle without connecting them to the ends of the sequentially connected fixed length tubes 3. Next, piping is installed between the manholes lb and lc.

In this case, the remaining portion 4b of the cutting auxiliary pipe 4a used in the previous section is used for piping in this section. This remaining auxiliary pipe 4b also has a pipe holder □41 at one end and a straight pipe at the other end, similar to the cutting auxiliary pipe 4a or the fixed length pipe 3, so this straight pipe part is connected to the inlet of the manhole lb. Insert and connect the receiving part 21', and then connect the fixed length tubes 3 in sequence. This fixed length tube 3
and the pipe inlet 22 which is the outlet of the manhole lc.
1 by using an auxiliary pipe 4c of length 1 obtained by cutting another auxiliary pipe 4. The remaining auxiliary pipe 4d is used for connecting the next section. Incidentally, the remaining auxiliary tube 4b can also be connected to the middle or end of the connection between the fixed length tubes 3. below,
Similarly, each section is piped using the remainder of the cut auxiliary pipe used in the previous section, the required number of fixed-length pipes, another auxiliary pipe, and pipes cut to a predetermined length.

As described above, the piping method of the present invention uses an auxiliary pipe having pipe holders □ at both ends, and ``in a certain section, small intervals that are created by connecting the standard length pipes and cannot be connected with the standard length pipes are connected by cutting the auxiliary pipes. Use one of the specified length,
Since the other tube is used in the next section, the auxiliary tube can be used without wasting it, and it is economical because there is no need to cut a fixed length tube and waste the remaining tube.
