るといつた欠点があつた。 Ceramic is very effective as an inner lining material for pipes used to transport the above substances.
It has been put into practical use for some time. However, conventionally known ceramic lining materials are either a single plate-shaped ceramic plate or a plurality of ceramic plates pasted onto a sheet large enough to be transported, and both of these materials are suitable for the pipe to be lined. Because the plate is directly attached to the inner surface with an adhesive, the adhesive strength tends to vary and the plate tends to peel off during fluid transport. Fluid energy acts on the bonded interface of the ceramic plates, causing them to peel off one after another.Moreover, it takes a lot of effort to install, resulting in poor construction efficiency and high construction costs. In particular, if the pipe to be lined has a small or medium diameter that the worker cannot enter inside, or if it is long, the workability is worse, and the range that can be lined is limited to the range that the worker can reach. The drawback was that the size of the pipe to be lined was limited. In addition, there was a drawback in that unreasonable gaps were formed between individual ceramic plates or at joints between plate sheets, which accelerated the above-mentioned flaking phenomenon.

い。 Next, a construction method for obtaining a ceramic lined pipe having the structure as shown in FIG. 1 using the ceramic lining block 4 having the above structure will be briefly described. Number of ceramic lining blocks 4
As shown in FIG. 5, a plurality of ceramic liners are fitted into a guide tube 5 which is fixedly installed concentrically with the pipe to be lined 1 outwardly from one end in the axial direction of the pipe to be lined 1. The block 4 is aligned and held concentrically with the pipe to be lined 1. Next, an epoxy adhesive or the like is applied to the outer circumferential surfaces of the four groups of ceramic lining blocks held in alignment, that is, the entire outer circumferential surface of the two groups of rubber cylinders and the entire inner circumferential surface of the pipe to be lined 1. After applying an adhesive or a lubricant, and before the adhesive hardens, a hydraulic cylinder is provided with the four groups of aligned ceramic lining blocks on the outer periphery of the guide tube 5 in a concentric state therewith. Usage pusher 6
The four groups of ceramic lining blocks are pressed or fixedly laid over the entire inner surface of the pipe to be lined 1 by pushing them all at once into the pipe to be lined 1 through the outer periphery of the rubber cylinder body 2. The groove 2A formed on the surface compensates for the difference between the outer diameter of the ceramic lining block 4 and the inner diameter of the pipe to be lined 1 when the ceramic lining block 4 is pushed in by elastic compression of the rubber cylinder portion 2B between the grooves 2A and It plays the role of absorbing by avoiding elastic deformation into the groove 2A, and whether the groove 2A is a circumferential groove as shown in FIG. 6 or a lattice-shaped groove as shown in FIG. Moreover, even if there is no groove, it is possible to push it in if a soft rubber material is used.

もよい。 The target pipe to be lined may be an existing pipe or a newly installed pipe, and may also be a round pipe or a square pipe, and the adhesive may be applied only to the outer circumferential surface of the four groups of ceramic lining blocks or Lining pipe 1
The adhesive may be applied only to the inner circumferential surface of the pipe, and in either case, the adhesive acts as a lubricant when the four groups of ceramic lining blocks are pushed into the pipe, allowing smooth pushing. Furthermore, if the ceramic lining block 4 is simply pressed onto the inner surface of the pipe to be lined 1, a lubricant may be used instead of the adhesive, or no lubricant may be used at all. or,
When pushing in the blocks 4, instead of pushing them all at once, they may be pushed one by one or a plurality of blocks one after another.

た。 The ceramic lining block of the present invention is
As is clear from the above explanation, it is a cylindrical block made by fixing a plurality of ceramic plates at least in the circumferential direction to the inner peripheral surface of a rubber cylinder. The desired ceramic lining can be easily applied by positioning and fixing the ceramic plate to the inner surface of the pipe or cylinder through the rubber cylinder, so it is not affected by transport fluid pressure or pulsation. There is no chance of it peeling off unexpectedly. Therefore, it is much more advantageous in terms of construction efficiency and construction cost than conventional products such as the plate-shaped ceramic alone or ceramic sheet mentioned above, and the inner surface is smooth and there is no problem such as pressure drop in fluid transport. It is possible to reliably form a lining layer, and it can also be applied to pipes that cannot or are difficult to construct with conventional lining materials, such as small-medium diameter pipes and long pipes. Moreover, not only is it easy to reduce costs through mass production, but production management and inventory management are also easy.
