摘要： PURPOSE:To form homogeneous and economic reinforcing earth by mixing untangled and separated fiber materials while dispersing and stirring earth having optimum water content ratio three dimensionally, and supplying a specific amount of a specific fiber material at a specific speed, if necessary. CONSTITUTION:Earth having optimum water content ratio corresponding with sorts of earth is dispersed and stirred with a mixer 40 three dimensionally. After that, a fiber material 28 carried by a carrier 21 is untangled and separated at an untangling and separating section 24 to form a separated fiber material 28a. Then, the fiber material 28a is dispersed and mixed little by little into earth being dispersed and stirred with the mixer 40 to form fiber mixing earth, and it is used for a filling structure, ground reinforcement, etc. If necessary, the fiber material 28 has 50-2000 denier in thickness and 50-200mm in length, mixing ratio against earth is 0.05-2wt.%. In addition, supply rate of the fiber material 28a against earth is less than 0.1wt.% per minute. According to the constitution, the homogeneous fiber mixing earth can be economically formed and, at the same time, a stabilized steep slope filling construction can be easily constructed within a short construction period of time.

摘要： PURPOSE:To easily prevent the separation and dispersion of the short-fiber-mixed soil, when the short-fiber-mixed soil sent under pressure is discharged. CONSTITUTION:A discharge head 7 consists of a cylindrical member which extends in the direction crossing with the horizontal direction as the discharge direction of the short-fiber-mixed soil supplied from a force feed hose 5, i.e., downward, and whose upper end is closed and the lower end is opened, and whose diameter is spread downward, and on the inner peripheral surface of the cylindrical member, the discharge nozzle 7a of the force feed hose 5 is opened along the inner peripheral surface. Thus short fiber-mixed soil which is discharged into the cylindrical member from the top end opened port of the discharge nozzle 7a by the sending pressure is released from the sending pressure, and decelerates its speed during the transfer in a spiral form along the inner peripheral surface of the cylindrical member, and is discharged at a low speed in nearly the same shape as that of the lower end opened port part, directly under from the lower end opened port part.

摘要： PROBLEM TO BE SOLVED: To know a correct amount of water storage by providing an air venting part to release air between an inside bag and a water storage tank in the inside bag mounted on the inside of a tank and/or in the water storage tank. SOLUTION: An inside bag S is formed of a composite sheet made by covering and impregnating a foundation fabric made up of a polypropylene fabric or polyethylene fabric with a resin such as a polyvinyl chloride or polyethylene. At the time of installation, air venting portion 11 made of a polyvinyl chloride pipe is provided on the inside bag S and for a water storage tank T. The folded inside bag S is introduced into the water storage tank from an introduction channel portion 2. The inside bag S is spread and contacted to the internal wall of the water storage tank T and bound, and the inside bag S and the water storage tank T are sealed at the introduction channel portion 2. Water is fed into the water storage tank T from the opening of the introduction channel portion 2, and air existing between the inside bag S and the water storage tank T is vented through the air venting portion 11. Thus it is possible to know the amount of water storage correctly.

摘要： PROBLEM TO BE SOLVED: To provide a ground reinforcing structure having little settlement, high strength and a large ultimate bearing capacity and improving a traffic vibration damping effect and a vibration control effect by arranging and stacking multiple sandbags, and practically integrating the sandbags constituting a stratified object. SOLUTION: A bag-like object integrated with a cord-like object is used to form a sandbag 2 in advance, and multiple sandbags 2 are connected by attached cords. Two or more stratified objects 4 arranged with the sandbags 2 are stacked, and a ground reinforcing structure 1 practically integrating the sandbags 2 constituting one or more stratified objects 4 is formed. When two or more layered product 4 are used, the length of the bottom side of an upper stratified object 4 is made the length of the bottom side of a lower stratified object 4 or below. A foundation 6 is formed on the reinforcing structure 1 to suppress ground settlement, and the soil grains in the sandbags 2 below the foundation 6 are expanded by an upper mount load. The sandbags 2 themselves are solidified by the reaction of the sandbags 2, the sandbags 2 are integrated with the foundation 6 of a building to exhibit a high hearing capacity, and the settlement into the ground 5 can be largely suppressed.

SOLUTION: The raschel knitted fabric has a rhombic division- or grid-like knitted ground tissue having a mesh structure and has many three-dimensional loop piles on at least one surface of the ground tissue. The raschel knitted fabric has a mesh structure knot of 5-50 mm and has a length of 2-20 mm between the loop base portion and loop tip portion of the loop pile. The loop piles are formed in a state that the knots of the loop piles are entangled with the knots of the stitches of the ground tissue, and the ground tissue has the loop piles in an amount of 0.5-3 piles/stitch of the ground tissue. The ground tissue is formed of ground yarns each having a total fineness of 200-6,000 denier and a strength of >=3 g/denier. The loop piles are formed of loop yarns each having a total fineness of 50-4,000 denier and an initial tensile elastic modulus of 330-1,000 kg/mm2.
