Therein, a packing 13 is arranged while interposing the edge of the tube 3 over the outer surface whole circumference of the main pipe corresponding to main pipe side both edge parts of the cover to prevent resin leakage. Further, irrespective of the size of diameter of the branch pipe 2, reliable closure between the cover and the branch pipe is materialized by the use of filler resin. By virtue of the resin filling, tight sealing between the cover inner surface and the branch part outer surface is provided. Thus, high corrosion prevention can be assured by a simple structure.

摘要： PROBLEM TO BE SOLVED: To prevent breakage of a polyethylene sleeve and erosion of a pipe caused by water intrusion from an end.SOLUTION: In a polyethylene sleeve 11 for preventing pipe erosion covered on an outer periphery of a pipe 1 buried underground, a water-absorbing swelling material 22 is provided on an inner peripheral side of a basic sleeve material 21 constituting an outer layer, and the water-absorbing swelling material 22 is sandwiched between the basic sleeve 21 and the pipe 1. The water-absorbing swelling material 22 on the inner peripheral side of the basic sleeve material 21 functions as a seal material, and thus, water intrusion from an end of the polyethylene sleeve 11 can be prevented. Even when breakage occurs in the basic sleeve material 21, the water-absorbing swelling material 22 swells by intrusion of groundwater, and functions as a self-repair material for closing the breakage, and therefore, water shielding performance can be maintained, and erosion of the pipe 1 can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a corrosion-preventive structure of pipeline which simply improves corrosion-preventive performance of buried pipeline.SOLUTION: A corrosion-preventive structure of pipeline in which an outer circumference of buried metal pipe is covered with polyethylene sleeve, adjacent edge parts of the polyethylene sleeves are overlapped with each other, a rubber band is wound around the outer circumference of overlapped part of the polyethylene sleeve and, thereby, water permeation from the edge part of the polyethylene sleeve is prevented, comprises water-absorbing swelling material disposed between the outer circumference of the pipe and the inner circumference of the rubber band. Thereby, even when water permeation occurs from the edge part of the polyethylene sleeve to the inner side, the water-absorbing swelling material is swollen, therefore, closes an advancing path of water, strengthens the tightening by means of the rubber band, stops the water permeation to the buried pipeline and can prevent corrosion of the pipeline.

摘要： PROBLEM TO BE SOLVED: To further improve corrosion resistance of an external surface spray coated pipe which is made of cast iron or steel and has a corrosion preventive layer of Zn-Al pseudo alloy on an external surface.SOLUTION: A corrosion preventive layer formed on an external surface of a pipe by metal spray coating is made of a pseudo alloy layer which is a mixture of a zinc layer and an aluminum alloy layer containing magnesium and silicon. This lowers the potential of an external surface spray coated pipe in a corrosive environment compared to one having a conventional corrosion preventive layer of which aluminum alloy forming the pseudo alloy layer does not contain magnesium. As a result, a sacrificial anode effect is increased to increase corrosion resistance of the pipe, extending corrosion-resistant life.

摘要： PROBLEM TO BE SOLVED: To supply fluid material (a) by dividing into multi-steps of supplying quantity in simple structure.
SOLUTION: A partition wall 14 having discharging hole 16 is formed in a hopper (vessel) 10 and when a discharging hole 13 at the lower side is opened, the fluid material of quantity according to the size of the discharging hole is naturally dropped from the discharging hole 13 and supplied at the beginning. At that time, the fluid material in a chamber 15b at the upper side is made to flow out to a chamber 15a from the discharging hole 16. When this supply continues for a certain time, the fluid material in the chamber 15a at the lower part is not made to flow out from the discharging hole 13, since the discharging hole 13 at the lower side is larger than the discharging hole 16 at the upper part, and when the discharge from the chamber 15b at the upper side continues, the discharged fluid material is passed through the discharging hole 13 in the chamber at the lower side without almost contacting with the periphery of the discharging hole 13 and dropped down and supplied, since the discharging hole 16 at the upper side is included into the discharging hole 13 at the lower side when viewed in plan. This supply quantity is determined depending on the size of the discharging hole 16 at the upper side.

Outer circumferences of a pipe 1 to be joined together with a joint part 2 are covered with the polyethylene sleeve 11 respectively over the pipe axial direction, the joint part 2 is covered with the polyethylene sleeve 11 which clads one side pipe 1 and, on the other hand, the polyethylene sleeve 11 gets over the joint part 2 and covers the polyethylene sleeve 11 which clads the other side pipe 1. In the polyethylene sleeve 11, the foam sheet or the air bubble sheet of the cushioning material 22 is soft, is excellent in cushion property, is hardly water-permeable and water-absorptive and is almost moisture-impermeable and, therefore, only by covering the outer circumference of the metallic pipe 1 with the polyethylene sleeve, the occurrence of cleavage accompanied by back-filling of earth and sand, or the like can be prevented.
