Abstract

PURPOSE:To enable execution of back-filling of a hard tube lining reliably extending over the whole length at favorable execution efficiency, by a method wherein casting into a gap to be generated between a pipe line and hard tube lining is performed by making use of pressure casting and vacuum suction casting together. CONSTITUTION:Both ends of a gap 3 to be generated between a pipe line 1 and hard tube lining 2 formed within the pipe line 1 through application of heating, pressurizing and expanding techniques to the inside of the pipe line 1 is closed with plugs 4, 4. When a liquid agent such as epoxy resin is sucked and depressurized by actuating a vacuum generating device 6 from one end side of the gap 3 while pressurizing and supplying the same through the other end side of the gap 3 by actuating a pressure casting device 5, the same is filled out effectively into the gap 3 through casting. Then an expanded casting passage part 3a extending in an axial direction of a pipe is formed in a part of the gap 3 and the liquid agent can be cast and filled into the gap 3 also. A hard tube 2' having a recessed groove 3'a on an external circumferential surface is used as, for example, a lining material, in the casting passage part 3a.

間を超え、作業中断を余儀なくされることがあった。Conventional technology and its problems As a conventional method for lining the inner surface of a pipeline, a hard tube with a smaller diameter is inserted into the pipeline, and then the tube is heated and pressurized from the inside to expand and line the inner surface of the pipeline. A construction method has been proposed that involves stretching. Since the hard tube lining formed by applying such a heating and pressurizing expansion method is itself hard and has shape-retaining properties, it is possible to omit the application of an adhesive as seen in soft tube linings. However, due to thermal contraction after expansion under heating and pressure, a gap inevitably occurs between the pipe and the hard tube lining, and this gap becomes a flow path for groundwater to enter through joints, preventing groundwater from entering the pipe. I will invite you. Infiltration of groundwater into the pipeline can be prevented by backfilling the gap by filling it with a liquid such as epoxy resin, but since the opening width of the gap is small and the injection filling resistance is large, it is difficult to use injection filling. It takes time, and depending on the length of the pipe, the pot life of the liquid agent may be exceeded, forcing the work to be interrupted.

本発明はこのような従来の問題点を一掃することを目的
としてなされたものである。The present invention has been made with the aim of eliminating such conventional problems.
