本発明は老巧化した石綿セメント管からなる水道配管を
新たな配水管と取り換える際の敷設工法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application) The present invention relates to a construction method for replacing aged water pipes made of asbestos-cement pipes with new water pipes.
(従来の技術)
水道配水管に使用される配水用管は種々のものが使用さ
れているが、石綿セメント管は価格が安い乙と、耐蝕性
が比較的高いことから簡易水道等に広く使用されてきた
。然し乍ら酸性上に弱く、且つ外力に弱いため、破損そ
の他の理由によって取り換えの必要が生じてくる。(Prior art) Various types of water distribution pipes are used for water distribution pipes, but asbestos cement pipes are widely used for simple water supply, etc. due to their low price and relatively high corrosion resistance. It has been. However, since it is weak against acidity and external force, it becomes necessary to replace it due to breakage or other reasons.
水道配管の取り換えの一段的手法は埋設管をta リ起
し、新設管を埋設する手段と、既設管は放置しておき新
設管を埋設する手段がある。One-step methods for replacing water pipes include raising the buried pipes and burying new pipes, and leaving the existing pipes alone and burying new pipes.
(発明が解決しようとする問題点)
既設管の[1)起し、新設管を埋設する手法は敷設部の
開削を行わなければならなく、周辺地盤の変状建設公害
等を考慮しなければならない。(Problems to be solved by the invention) The method of (1) raising the existing pipe and burying the new pipe requires excavation of the installation part, and consideration must be given to deformation of the surrounding ground and construction pollution. It won't happen.
また開削工事をせずに新設管を埋設する手段としては、
シールト工法、ノースパイラル工法等と称せられる工法
が公知であるが、これ等の工法は煩雑で且つ工事費用が
嵩むと共に、放置された既設管が破損すると、その管定
間が路面陥没の原因となったりする。In addition, as a means of burying new pipes without excavation work,
Construction methods called the seal construction method and the no spiral construction method are well known, but these construction methods are complicated and increase construction costs, and if the existing pipes are left unused and damaged, the gap between the pipes can cause road surface subsidence. It happens.
(問題点を解決するtコめの手段)
そこで本発明は開削工事を行わずに非常に簡単な手法で
管の更新を行うようにしたものである。即ち本発明は既
設の石綿セメント管内に、既設管を破壊しながら進行す

管を押入して新設管を敷設するようにしたものである。(Top Means to Solve the Problem) Therefore, the present invention is designed to renew the pipe using a very simple method without performing excavation work. That is, in the present invention, a pipe breaking device that advances while destroying the existing pipe is sent into an existing asbestos cement pipe, and a new pipe is pushed in following the device to lay the new pipe.
従って既設管理設個所の適当間隔位置に縦穴を掘削し、
縦穴間毎に新設管と取り換えていけば良いもので、特に
新規な管路掘削を行う必要がなく、且つ既設管の位置に
新設管を敷設するので周辺地盤に変化を与えないもので
ある。Therefore, vertical holes are drilled at appropriate intervals between the existing management facilities.
It is sufficient to replace each vertical hole with a new pipe, so there is no need to excavate a new pipe, and since the new pipe is laid at the location of the existing pipe, there is no change in the surrounding ground.
(実施例) 次に本発明の実施例について説明する。(Example) Next, examples of the present invention will be described.

ものである。Vertical holes 2 and ends are drilled between the asbestos-cement pipes to be replaced at suitable buried locations in the existing water distribution pipeline 1, one hole 2 is equipped with a suppression device M3 consisting of a hydraulic cylinder 7, and the other hole is equipped with a suppression device M3 consisting of a hydraulic cylinder 7. A winch 4 is installed and a pipe breaking device 5 is sent into the water pipe WJl. The pipe breaking device 5 may have a breaking part 6 that becomes thinner or thicker, and for example, a conical body 8 that is moved back and forth by a hydraulic cylinder 7 is provided in the radial breaking part 6. Then, the guide rope 9 is passed through the water distribution pipe 1, and the pipe breaking device 5 is pushed into the water distribution pipe 1 through the vertical hole 2, and the ends of the guide rope 9 are tied together and pulled in. A newly installed pipe B of a cast pipe is connected to the pipe breaking device 5, and a hydraulic pipe 1O and a muddy water supply pipe 11 are connected to the pipe breaking device 5 through the inner space of the newly installed pipe B. Hydraulic oil is supplied to the pipe, and muddy water is spouted from behind the pipe breaking device. When the pipe breaking device M5 is pushed into the pipe line 1 and the hydraulic cylinder 7 is activated to make the crushing part 6 thicker, the old asbestos cement pipe A is destroyed. The pipe breaking device 5 is pulled by the guide rope 9 and pushed in by the suppressing device 3. This is repeated one after another, and the new pipe B is sent in sequentially following the pipe breaking device M5, and when the pipe breaking device 5 reaches the other vertical hole 2, the existing water distribution 7II 51 is completely replaced with the new pipe B. It is.
