本発明は、管内に供給した液状ライニング材
を、管内を移動させる物体により管内壁面に塗布
する方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for applying a liquid lining material supplied into a pipe to the inner wall surface of the pipe using an object that moves within the pipe.
上記方法を実施するに、従来、例えば特開昭51
―86545号公報に示されるように、管内面全体に
塗布するに足る量の液状ライニング材を一度に供
給し、その大量のライニング材を移動物体で管長
手方向及び管周方向に押圧移動させていた。しか
し、その場合、殊に初期において物体の移動抵抗
が大きくなり、物体移動に強力な装置を必要とし
たり、物体の移動速度が急激にかつ頻繁に変化し
て、管内壁面に付着させた液状ライニング材の厚
さが不均一になつたり、あるいは、長い管や高粘
度のライニング材を対象にできない等の欠点があ
つた。 To implement the above method, conventionally, for example, JP-A-51
- As shown in Publication No. 86545, an amount of liquid lining material sufficient to coat the entire inner surface of the pipe is supplied at once, and a large amount of the lining material is pressed and moved in the longitudinal direction and circumferential direction of the pipe using a moving object. Ta. However, in this case, the resistance to the movement of the object becomes large, especially in the initial stage, and a powerful device is required to move the object, and the moving speed of the object changes rapidly and frequently, causing the liquid lining to adhere to the inner wall surface of the pipe. There were disadvantages such as uneven thickness of the material and inability to handle long pipes or high-viscosity lining materials.
本発明の目的は、物体の移動抵抗を大幅に軽減
できるようにして、上述の諸欠点を一挙に解消す
ることにある。 An object of the present invention is to eliminate the above-mentioned drawbacks all at once by making it possible to significantly reduce the movement resistance of objects.

の充填した液状ライニング材のうち余剰分を管か
ら排出し、管内壁面に付着した液状ライニング材
を、前記物体の移動によつて均厚化させることに
あり、その作用効果は次の通りである。 The characteristic means of the present invention is to fill the pipe with a liquid lining material before moving an object inside the pipe, and to discharge the surplus of the filled liquid lining material from the pipe, so that the liquid lining material adheres to the inner wall surface of the pipe. The purpose is to make the thickness uniform by moving the object, and its effects are as follows.
つまり、液状シール材をその管内充満と余剰分
流出によつて、管内壁面の全体にわたつて薄くか
つ確実に付着させることができ、その薄く付着さ
せた液状ライニング材を物体によつて均厚化させ
るだけであるから、液状ライニング材に起因する
物体の移動抵抗を、前述の従来法に比して常に大
幅に軽減できかつほぼ一定にできる。 In other words, the liquid sealing material can be thinly and reliably adhered to the entire inner wall surface of the pipe by filling the pipe and letting the excess flow out, and the thinly deposited liquid lining material can be uniformly thickened by an object. Therefore, the movement resistance of the object caused by the liquid lining material can be significantly reduced and kept almost constant compared to the above-mentioned conventional method.
その結果、物体の管内移動を、簡便な設備によ
つて容易に、かつ、常にほぼ一定の速度で行わせ

かつ簡単に施せるようになつた。また、たとえ、
長い管であつてもあるいは高粘度の液状ライニン
グ材であつても、容易かつ確実に良好なライニン
グを施せるようになつた。 As a result, it has become possible to move objects within the pipe easily and always at a nearly constant speed using simple equipment, and it has become possible to reliably and easily apply a lining of uniform thickness. Also, even if
It has become possible to easily and reliably apply good linings to long pipes or with high viscosity liquid lining materials.
次に、例示図により本発明の実施例を説明す
