摘要： PROBLEM TO BE SOLVED: To provide a method for regenerating not only an existing pipe having small diameter but also an existing pipe having large diameter economically.
SOLUTION: A temporary water drain pipe having smaller outside diameter than inside diameter of an existing pipeline is installed in the existing pipeline. A cylindrical pipe to be regenerated having smaller outside diameter than inside diameter of the existing pipeline and larger inside diameter than outside diameter of the temporary water drain pipe is installed at the outer periphery of the temporary water drain pipe as a single unit. The pipe to be regenerated as the single unit is pressurized and moved in the direction of the pipeline inside the existing pipeline to pressurize the single units sequentially and form a continuous body of pipes to be regenerated. A grout material is poured between the outer periphery of the continuous body and the inner periphery of the existing pipe and is hardened.

摘要： PROBLEM TO BE SOLVED: To provide a concrete structure to be used in an environment in contact with sea water and improved in durability by promoting deposition and breeding of marine lives on the surface, and to provide a method for suppressing corrosion of a steel bar in a concrete structure.
SOLUTION: The concrete structure is suitable to be used in an environment in contact with sea water and has a slow deterioration rate showing 0 to 35 mm permeation depth of chloride ions after six months of the contact state with sea water. The method for suppressing corrosion of a steel bar in a concrete structure is carried out by depositing and breeding marine lives on the surface of the concrete structure. The concrete structure covered with marine lives suppresses permeation of substances such as chloride ions causing deterioration of the structure and is significantly improved in durability.

摘要： PROBLEM TO BE SOLVED: To prevent cracking on the surface of a concrete structure at a low cost by using a concrete form made by forming a porous concrete layer on the surface of a water-stop board and then pouring concrete at the porous concrete layer side of this concrete form.
SOLUTION: A concrete form 1 is constituted by forming a porous concrete layer 12 on one surface of a water-stop board such as a wood board or synthetic resin board to one united body. Here, the porous concrete used has mane pores, a low elasticity and a small thermal conductivity, and the thickness of the porous concrete layer 12 is sufficiently large for easing thermal transmission and propagation of cracking. For the water-stop board 11, a PIC slab (a permanent type frame with a high durability) or a precast slab may be used. After assembling this form 1 to a predetermined shape, structural concrete 2 constituting a concrete structure is placed at the side of porous concrete layer 12 of the form 1.
