Description
【発明の詳細な説明】 ［産業上の利用分野］ この発明は、埋設管の補修方法に関するものである。[Detailed description of the invention] [Industrial application field] The present invention relates to a method for repairing buried pipes.
［従来の技術］
従来、水道管等の埋設管に漏水が生じた場合、−
一時的に給水を停止し、漏水箇所の地面を掘削して、埋
設管を補修していた。[Prior Art] Conventionally, when a water leak occurs in a buried pipe such as a water pipe, the water supply is temporarily stopped, the ground at the leak location is excavated, and the buried pipe is repaired.
［発明が解決しようとする課題］
しかしながら、上述した補修方法は、次のような問題を
有している。即ち、給水を一旦停止する必要があるので
、その間断水する。断水時間が水道使用量のピーク時で
ある場合には、断水による影響は大きい。[Problems to be Solved by the Invention] However, the above-mentioned repair method has the following problems. That is, since it is necessary to temporarily stop the water supply, the water supply is interrupted during that time. If the water outage occurs during peak water usage times, the impact of the water outage is significant.
従って、この発明の目的は、漏水が生じた埋設管を容易
且つ短時間に補修することができる方法を提供すること
にある。SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a method for easily and quickly repairing a leaking buried pipe.
［課題を解決するための手段］
この発明は、埋設管からの漏水により洗掘りされて形成
された地中の空間内に、地上から発泡樹脂原料を注入し
て、前記発泡樹脂原料を前記空間内で発泡させ、かくし
て、前記空間を発泡樹脂により埋め、これによって、前
記埋設管からの漏水を防止することに特徴を有するもの
である。[Means for Solving the Problems] The present invention injects a foamed resin raw material from above ground into an underground space formed by scouring due to water leakage from a buried pipe, and injects the foamed resin raw material into the space. This method is characterized in that the space is filled with foamed resin, thereby preventing water leakage from the buried pipe.
次に、この発明の、埋設管の補修方法の一実施態様を、
図面を参照しながら説明する。Next, an embodiment of the buried pipe repair method of this invention is as follows.
This will be explained with reference to the drawings.

間２内で発泡させ、これによって、漏水が生じている埋
設管１の周囲を発泡樹脂４によって被覆するものである
。As shown in Fig. The foamed resin raw material 3 is injected through the injection pipe 5 and foamed in the space 2, thereby covering the periphery of the buried pipe 1 where water is leaking with the foamed resin 4.
このように、空間２内を発泡樹脂４により埋めることに
よって、土荷重や車両荷重等による地盤沈下が防止され
る。By filling the space 2 with the foamed resin 4 in this manner, ground subsidence due to soil loads, vehicle loads, etc. is prevented.
軽度の漏水は、この発明の方法により停止するが、漏水
量が著しい場合には、水道使用量が少ない深夜までの応
急処置として、この発明の方法を適用する。これにより
、断水による影響を最小限に押えることができる。Mild water leaks can be stopped by the method of the present invention, but if the amount of water leakage is significant, the method of the present invention is applied as an emergency measure until late at night when water usage is low. This makes it possible to minimize the impact of water outages.
発泡樹脂４の比圧縮性は、地上の発泡樹脂注入機６にお
いて、発泡樹脂原料の組成を変えることにより変えるこ
とができる。The specific compressibility of the foamed resin 4 can be changed by changing the composition of the foamed resin raw material in the foamed resin injection machine 6 on the ground.
