の付帯設備を組合せ設置して構築されていた。(Prior technology) In general, sewerage pipes are constructed using fume pipes, hard vinyl chloride pipes, reinforced plastic composite pipes, cast iron pipes, etc., which are buried underground and connected at intervals of approximately 0.6 to 4 m to form conduits. They were constructed by installing manholes and other incidental equipment at various locations.
そしてこれらの構成は流下方式あるいは圧送方
式のいづれにあつても概ね同様のものである。 These configurations are generally the same regardless of whether the system is a downstream system or a pressure-feed system.

等の重大な問題を発生させる恐れがある。(Problem that the invention aims to solve) However, in recent years, especially as various structures have become larger, there have been many opportunities for large vibrations to occur due to underground burying work and ground displacement due to such burying work.
These amplify vibrations and displacements, particularly in long sections, and may damage the connections between the conduits or the connections between the conduits and incidental equipment such as manholes, leading to water leakage. Such water leakage may cause serious problems such as environmental pollution due to sewage leaking underground from the pipes and an increase in the amount of sewage treatment due to rainwater, groundwater, etc. flowing into the pipes.
（問題点を解決するための手段）
ここに考案者等はかかる問題を解決すべく鋭意
検討を重ねた結果この考案を完成したのである。(Means for Solving the Problems) The inventors completed this invention after intensive study to solve the problems.

更に該外管により内管が保護されることになる。
そして仮に内管に漏水部が生じても直ちに地中に
汚水が浸出することがなく、又逆に地下水等の直
接侵入が生じない。(Function) With the above structure of the sewer pipe of the present invention, the outer pipe made of a corrugated pipe increases flexibility and absorbs distortion caused by vibration etc., so damage to the above connection parts etc. is avoided.
Furthermore, the inner tube is protected by the outer tube.
Even if a leak occurs in the inner pipe, sewage will not immediately seep into the ground, and conversely, underground water will not directly intrude.
（実施例） 第１図によりこの考案の実施例を説明する。(Example) An embodiment of this invention will be explained with reference to FIG.
１は低密度ポリエチレンによる内径78mm、外径
89mmの内管であり、２は高密度ポリエチレンによ
る内径100mm、外径130mmの波付外管である。 1 is made of low-density polyethylene with an inner diameter of 78 mm and an outer diameter.
The inner tube is 89 mm, and 2 is a corrugated outer tube made of high-density polyethylene with an inner diameter of 100 mm and an outer diameter of 130 mm.
これら内外管は相互に固着することなく図のよ
うに組合せ、相互の空隙は内管断面積に対して34
％を保持させた。 These inner and outer tubes are assembled as shown in the figure without being fixed to each other, and the mutual gap is 34mm relative to the cross-sectional area of the inner tube.
% was retained.

て使用される。 In this invention, both the inner tube and the outer tube are made of polyethylene, polypropylene, vinyl chloride,
It is made of plastic material such as ABS resin or cross-linked polyethylene, and it is made of plastic material such as ABS resin or cross-linked polyethylene, and in particular, it has metal wires or fiber strips 3 embedded in a spiral shape as shown in Figure 2 for reinforcement of the outer tube, etc., depending on the purpose of use. The material, shape, structure, etc. are appropriately selected from those commonly used.
内管はその内面を平滑なものとして流水性を高
めるようにし、外管は上記の如く波付管として可
撓性及び耐圧強度を向上させるものとする。 The inner tube has a smooth inner surface to improve water flow, and the outer tube has a corrugated tube as described above to improve flexibility and pressure resistance.
内管及び外管相互は適度の間隙を保持するよう

めの好ましい上記空隙量は内管断面積に対して10
％以上である。 The diameters of the inner and outer tubes are appropriately determined and combined so as to maintain an appropriate gap between them, but the preferable gap amount for water retention etc. is 10% relative to the cross-sectional area of the inner tube.
% or more.
かかる空隙部には、上記漏水検出用の検知器を
予め設置して早期に導管内での漏水を検知し修復
作業を行い得るようにするのが得策である。 It is a good idea to install the water leakage detection detector in advance in such a gap so that water leakage in the conduit can be detected early and repair work can be carried out.

つことが確認し得た。 The conduit shown in the first diagram above should be installed 1.5 to 1.5 meters below the road surface of a general road.
In the case of a sewer pipe built at a depth of 6 m, it has been confirmed that it can withstand an internal pressure of 10 Kgf/cm 2 when used in a forced-feed system, and can withstand the weight of a 20-ton truck.
