摘要： PURPOSE:To form a plantable riverbank or bank or the like while preventing or reducing erosion of an earth surface by fluid by arranging fiber mixed soil on the earth surface in contact with the fluid. CONSTITUTION:Fiber mixed soil 7 formed by mixing short fiber by 0.1-2weight% to soil is arranged on a surface of earth 1. Even in repair or afteration, another fiber mixed soil 7 is arranged newly on the existing fiber mixed soil 7. Various fibers such as natural or inorganic or metallic fibers having, for example, a theckness of 1-100 denier and a length of about 10-200mm are selected as the short fiber according to its necessity. Even if fluid energy such as a running water flow or a wind is applied to a contact part 20 of such fiber mixed soil, since the short fiber erecting on a surface restrains rolling of a soil particle and reduces the fluid energy, so that erosion and scour can be prevented without generating a wave pattern on a surface of the mixed soil 7.

摘要： PURPOSE: To prevent water damage by forming a meshing sheet having a specific opening width into a sack shape, filling the sacks with short fibers and soil in a specified proportion by weight, and laying them on the surface of an embankment. CONSTITUTION: Sacks 1 are formed from a meshing sheet having an opening width of 0.1-50mm, and a mixture of a soil and short fibers below 5wt.% is formed, stamped, and put fully in each sack. The filled sacks 1 are laid along the slope face of an embankment B, and if necessary, coupled with the embankment B using piles. The oversurfaces of the sacks 1 are covered with soil, and lawn, etc., is implanted. If necessary, a meshing sheet in flat plate shaped is extended to the outside of the sacks and embedded under the ground in the condition spread horizontally so that they 1 are checked from movement by the earth pressure. This allows preventing erosion, soil outflow, crazing at drought, etc., and protecting the landscape of the nature and the ecosystem.

摘要： PURPOSE:To prevent outflow of soil of an inclined surface and also to improve the water holding property and air containing property by mixing at least water absorptive high polymer material in soil for forming the inclined surface. CONSTITUTION:A water absorptive high polymer material is mixed in soil E in an inclined surface forming area A. Water produced by rainfall R is absorbed by the water absorptive high polymer which is swollen, and the stickness is exhibited to hold the peripheral soil particles fast. When a short fiber material is mixed in soil E, the shearing strength can be increased in co-operation with the connecting action between the soil particles. Further, the high polymer material is increased in its volume like a gel, so that the water penetrating into the ground is cut off by the surface layer part. Thus, the outflow of soil due to rainfall can be prevented, and growing conditions of plants can be satisfied to promote the greening.

摘要： PROBLEM TO BE SOLVED: To provide a sewed bag suitable for pouring clay of high water content into the bag and dehydrating the clay in a dehydrating sewed bag which fabric is sewed to form by arranging water absorbing sheet bodies containing a polymer of high water-absorptivity on both the outer surfaces of a fabric sewed part and integrally sewing the water absorbing sheet bodies and the fabric of the sewed part. SOLUTION: A sewed bag 1 is formed into a bag by sewing fabric sheets 1a, 1b, and water absorbing sheet bodies 2a, 2b are arranged on both the outer surfaces of a fabric sewed part A to integrally sew the water absorbing sheet bodies 2a, 2b and the fabric 1a, 1b of the fabric sewed part A by sewing thread 3. Clay of high water content is poured into such sewed bag 1, and when the inner pressure of the sewed bag 1 is increased, a void is caused in the seam part, and the water content in the clay of high water content leaking from the void is absorbed by a polymer of high water-absorptivity of the water absorbing sheet bodies 2a, 2b, and also the water absorbing sheet bodies 2a, 2b are allowed to swell to close the void. In this way, the clay component in the clay of high water content remains in the sewed bag 1 to perform dehydration only.

摘要： PURPOSE:To make it possible to reinforce a mother soil and use this reinforced mother soil as a filling, a structure foundation and a road subgrade by compounding a large number of filaments in parallel, fixedly binding all the filaments integrally at both ends and dispersively mixing them into the mother soil. CONSTITUTION:A large number of soft filaments 1 are laid out in parallel and all the filaments 1 are fixed at both ends 2 and 3 where a reinforced material is mixed into a mother soil. In this case, each filament 1 between the both ends 2 and 3 are laid out in such a fashion that they may be subjected to deformation and bending discretely with a slight span. Synthetic fibers, such as polyester are used as the filament 1 from the view point of price, workability and corrosion resistance. The filaments 1 are turned into such a shape so that they may hold the soil easily, thereby providing excellent moisture and water absorbing properties. A unit piece 5 as their reinforcing materials is laid out by warping warps 6 and 7 while a ground fabric 8 is woven with the filaments 1 as a woof and cut so that they may be formed in length (L2) and width (W2). This construction makes it possible to improve the soil, erosion resistance and elevate the vapor phase in the soil and supply oxygen to the roots of a pant.

摘要： PURPOSE: To improve workability by using a mixed liquid containing cement, water and water swelling fibers, in which absorption, fiber length and a fiber diameter are specified, as a grout material forming an impervious wall by injection into the cracked section of a bedrock. CONSTITUTION: High water-absorbing fibers, in which absorption is decuple or more of their own weight, fiber length is 8-50mm and fiber diameters are 1-50 denier, are used as water swelling fibers. When a first grout material G1 , consisting of a fiber mixed liquid is injected into a foundation rock R, the first grout material G1 , is flowed into opened cracks K. The fluidity of the grout material G1 is increased because fiber surfaces absorb water and have smoothness at that time, and fibers are deposited in the cracks K at low injection pressure and close the cracks K. When a second grout material G2 composed of a cement suspension is infected at pressure higher than the grout material G1 the second grout material G2 is infiltrated and fixed into the cracks K and fine cracks in the peripheries of the cracks K and consolidated. All materials are mixed desirably, and one-stage execution of works is conducted. Accordingly, fluidity can be controlled easily, the dispersion of an injection liquid can be prevented, and strength can be increased.

摘要： PURPOSE:To obtain a specified thickness and a good water shielding property by placing two sheets of reinforcing base fabric on a face to be waterproofed and spraying a specified waterproofing agent over the fabric to impregnate the fabric to the rear face of the lowermost layer. CONSTITUTION:Two sheets of the reinforcing knit fabric having >=50% longitudinal breaking elongation, 2-10mm thickness and 0.08-0.16g/m density are placed on a face to be waterproofed, and a delayed-coagulation waterproofing agent having 5,000 to 30,000cps viscosity at 20 deg.C under pressure before coagulation and needing 10-60sec after the start of coagulation until 100,000cps is reached is sprayed over the fabric to impregnate the fabric to the rear face of the lowermost layer. Consequently, a waterproofing layer excellent in workability and water resistance and having a specified thickness is obtained.

CONSTITUTION:Water shielding outer sheets 11 each made of normal rubber or resin are laminated on both front and rear surfaces of water swelling foamable sheet 12 made of water swelling rubber foam or water swelling resin foam having 1.1-10 times of foaming magnification, 50-1000% of volume expansion coefficient after it is dipped in water for 10 hours, and 1-50kg/cm of swelling pressure after it is dipped in water for 10 hours. This sheet is reinforced with fiber sheet 13, and hence a collapsing elongation of the obtained entire sheet 10 is set to 50% or more, and its tearing strength is set to 10kg/cm or more. As the sheet 13, knitted fabric is preferable in view of the elongation, and as the knitted fabric, weft knitted fabric or particularly tubular knitted fabric is preferable.
