Abstract
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、1
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、給水を一端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 will be cut off during that time. If the water outage occurs during peak water usage periods, 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、地上から粒状発泡樹脂および硬
化剤からなる充填材を注入し、前記充填材を前記空間内
で硬化させることによって、前記埋設管からの漏水を防
止することに特徴を右するものである。[Means for Solving the Problems] The present invention injects a filler made of granular foamed resin and a hardening agent from above ground into an underground space formed by scouring due to water leakage from a buried pipe. The feature lies in preventing water leakage from the buried pipe by hardening the filling material within the space.
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.
2−
第1図は、この発明の、埋設管の補修方法の一実施態様
を示す断面図である。2- FIG. 1 is a sectional view showing one embodiment of the buried pipe repair method of the present invention.
第工図に示すように、この発明は、埋設管1の漏水口1
Aからの漏水により洗掘りされて形成された地中の空間
2内に、地」−の注入機3から、発泡スチロール等から
なる粒状発泡樹脂および硬化剤からなる充填材4を注入
し、充填材4を硬化させることによって、埋設管1から
の漏水を防止するものである。As shown in the construction drawing, this invention
A filler material 4 made of granular foamed resin made of expanded polystyrene or the like and a hardening agent is injected from an underground injection machine 3 into the underground space 2 formed by scouring by water leakage from A. By hardening the pipe 4, water leakage from the buried pipe 1 is prevented.
注入機3は、硬化剤容器5内の硬化剤とホッパ10内の
粒状発泡樹脂6とを混合槽7内で均一に混合し、このよ
うにして調製された充填剤2を圧送ポンプ8によって、
地中の空間2内に向けて挿入された注入管9を介して空
間2内に注入するものである。The injection machine 3 uniformly mixes the curing agent in the curing agent container 5 and the granular foamed resin 6 in the hopper 10 in a mixing tank 7, and pumps the filler 2 thus prepared by a pressure pump 8.
It is injected into the space 2 through an injection pipe 9 inserted into the space 2 underground.
このようにして、漏水によって形成された空間2内に、
軽量且つ比圧縮性の発泡欄脂からなる充填剤4を注入す
ることによって、土荷重や車両荷重等による地盤沈下を
防止できる。In this way, in the space 2 formed by the water leakage,
By injecting the filler 4 made of lightweight and compressible foamed ballast, ground subsidence due to soil loads, vehicle loads, etc. can be 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.
[発明の効果]
以上説明したように、この発明によれば、漏水が生じた
埋設管を、地面を掘削することなく短晴間に補修するこ
とができるという有用な効果がもたらされる。[Effects of the Invention] As explained above, according to the present invention, a useful effect is brought about in that a leaking buried pipe can be repaired in a short period of time without excavating the ground.
