ことにより可撓性を付与する遠心モルタルライニングパ
イプの製造方法に関する。Detailed Description of the Invention (Industrial Application Field) This invention provides a method for manufacturing a centrifugal mortar lined pipe in which flexibility is imparted by incorporating a mortar crack inhibitor into the entire mortar layer during the production of the centrifugal mortar lined pipe. Regarding.
(従来の技術)
一般にバイブ内ライニング法としては例えば特開昭50

層ライニングを行なうことが知られている。(Prior art) Generally, as a vibrator lining method, for example,
It is known that inner lining is performed using centrifugal force, as is known from Japanese Patent No. 110460.
而して、従来の遠心モルタルライニングパイプはモルタ
ル層の乾燥及び取扱い等によるパイプの変形や衝撃によ
りモルタル層忙クラックやパイプ内側表面との剥離が発
生し、問題視されている。Conventional centrifugal mortar-lined pipes have been viewed as problematic because cracks in the mortar layer and separation from the inner surface of the pipe occur due to deformation and impact of the pipe due to drying of the mortar layer and handling.

ル層内に留めることができない。As a countermeasure to this problem, it is known in the field of manufacturing mortar lining pipes for handcarts that a flexible mortar layer can be obtained by incorporating a crack preventive agent into the mortar compound. When a crack preventive agent is blended into the mortar compounding material for centrifugal lining, the crack preventive agent also comes out of the mortar layer due to centrifugal force and cannot be retained within the mortar layer.

ルタルライニングパイプの製造方法である。(Means for Solving the Problems) The present invention advantageously solves the above-mentioned problems, and its gist is to apply mortar crack preventive agent to the inner surface of the pipe and then apply mortar lining to the inner periphery of the pipe. This is a method for manufacturing a flexible centrifugal mortar lining pipe characterized by applying centrifugal force through rotation.
以下本発明を図面に示す実施例、態様例に基づいて具体
的に説明する。The present invention will be specifically described below based on embodiments and embodiments shown in the drawings.

〜40Gの遠心力を7〜30分程度かける。In FIG. 1, reference numeral 2 denotes a centrifugal mortar lining device for the inner surface of the pipe 1, and a mixing material 4 such as mortar supplied from a mixer 3 is charged into the rotating pipe 1. When manufacturing a centrifugal mortar lined pipe, the inner surface of the pipe is prepared and cleaned, and then a crack preventive agent of 5t20 to 200 f/d is sprayed or applied with a brush or the like on the inner surface of the pipe before mortar is added. After drying and curing for about 0 to 30 minutes, a mortar mixed wire material 4 adjusted in advance to an appropriate hardness and flow value of 135 to 165) was poured into the inner surface of the pipe.
Apply centrifugal force of ~40G for about 7 to 30 minutes.

ルタル内に留まる。The crack preventive agent 5 applied before centrifugal mortar lining enters into the mortar layer from the inner surface of the pipe at the same time as the water in the mortar is drawn out to the surface of the mortar layer by centrifugal force, and is dehydrated by centrifugal force and becomes dense gold. Remains within the raised mortar.
クラック防止剤の分布は、パイプ内側表面からモルタル
層内及び極く一部はモルタル層の表面に至ることもある
。The crack inhibitor may be distributed from the inner surface of the pipe into the mortar layer and, to a very small extent, to the surface of the mortar layer.
