Abstract

(57) [Summary] [Purpose] In civil engineering work, for example, to prevent clogging of underdrain drainage pipes at low cost and easily. In addition, the edge of the temporary pile and the concrete plate that is placed around it can be freely and arbitrarily constructed regardless of the shape, size, and dimensions of the temporary pile, which is excellent in handling and management. Therefore, it is to provide a low-cost curing material for construction work which is useful for practical use. [Structure] A core material formed by curling a foamed resin into a curl and having an appropriate length by elastically entwining it with an adhesive to form a desired thickness, width and length, and an outer periphery of the core material. It consists of an encapsulating water-permeable sheet or an impermeable sheet.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention is intended for the purpose of waterproofing clogging of underdrain drainage pipes in civil engineering, drainage treatment materials such as slopes, or temporary piles driven in the construction of underground structures and concrete plates driven around them. It is used as an edge-cutting material, etc.

[0002]

[Prior art]

 Conventionally, as a material to prevent clogging of underdrain drainage pipes, a plastic material is specially processed into a loofah shape, and a permeable sheet is wound around the outer surface of a molded core material, or a special pipe shape with water permeability. There is one in which a water-permeable sheet is wound on the outer surface of the core material. Further, a construction method disclosed in Japanese Patent Publication No. 62-56296 is disclosed and implemented as an edge cutting material for a temporary pile and a concrete plate.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional method has the function and effect as a clogging preventing material, but is costly and economically disadvantageous. In addition, the anti-concrete release member used in the method of constructing the concrete structure is a fixed shape injection-molded to correspond to the shape and size of the temporary pile. It requires several kinds of products, is extremely unreasonable in terms of manufacturing, management and handling, and is economically disadvantageous.

[0004]

[Means for Solving the Problems]

 The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to be provided at a low cost and to be able to arbitrarily cope with the shape and dimensions of temporary piles, etc., which is advantageous in manufacturing, management, and handling. The purpose is to provide a curing material for construction work that can be performed easily.

As a means for this, a material obtained by molding a foamed polystyrene resin, a foamed polyethylene resin, or the like into a curled shape and having an appropriate length is entwined in an elastic state with an adhesive to form a desired thickness, width and length. It is characterized by comprising a core material and a water-permeable sheet or a water-impermeable sheet covering the outer peripheral surface of the core material.

[0006] With the above structure, it is wrapped around the outer circumference of the underdrain drainage pipe to be backfilled to prevent clogging, or an edge cut with a concrete plate that is wound around the outer circumference of the temporary pile and placed around it. As a result, the appropriate elasticity makes it easy to wind around the outer circumference of a pipe or H-section steel, and it is possible to freely adapt to any size, shape, and size. To do.

【Example】

 The curing material 1 shown in FIG. 1 has a required thickness (about 30 mm) obtained by wrapping a material 2 obtained by molding a foamed polystyrene resin or a foamed polyethylene resin into a curl and having an appropriate length with one adhesive in an elastic state. .About.50 mm), width (about 300 mm to 500 mm) and length (2 m, 4 m, etc.), and a water-permeable sheet 4 covering the outer peripheral surface of the core 3. The curing material 11 shown in FIG. 2 comprises a core material 33 formed in the same manner as described above, and a water impermeable sheet 5 covering the outer peripheral surface of the core material 33.

The curing material for construction work according to the present invention is constructed as shown in FIG. 3 or FIG. 4 to FIG. Figure 3 shows the state of using the underdrain drainage pipe A in the earthwork when it is buried in the ground. By wrapping the curing material 1 around the outer periphery of the pipe A and backfilling it with B, rainwater or the like permeates the water-permeable sheet 4 of the curing material 1 and enters the inside of the pipe A for drainage treatment. FIGS. 4 to 6 show a state used when constructing a floor slab D by placing a concrete around the temporary pile C in the foundation work of construction. Fig. 4 shows a state in which the curing material 11 is wrapped around the outer circumference of the temporary pile C (H-shaped steel) and stopped with a tape, etc. FIG. 6 shows a state in which the temporary pile C is pulled out and the hollow portion (opening) is filled with another concrete d to close it. (The curing material 11 can be removed from the concrete surface and reused when the temporary pile C is pulled out or thereafter.)

[0009]

[Effect of device]

 As described in detail above, the curing material for construction work of the present invention can be manufactured at a lower cost than conventional products, requires no special molding technology and equipment, is economically advantageous, and is practically used. It is very effective. In addition, it is possible to respond freely and freely without being influenced by the size, dimensions, and shape of pipes or H-section steel, etc., it is extremely practical in handling and management, and efficient wastewater treatment is possible. The edge cutting effect between the pile and the concrete plate can be expected, and it can be provided as a practically useful curing material for construction work.
