摘要： PURPOSE:To build a banking with little sinking even on weak ground and of excellent natural view by building the banking by the use of light weighted and reinforced soil for the core part and short fiber mixing soil on the slope face part, and making it possible to be vegetative. CONSTITUTION:Light weight and reinforced soil 1 is used for the core part, and short fiber mixing soil 2 is used for the slope face part. The short fiber mixing soil 2 is constituted by mixing one or two among polyester fiber, polyamide fiber, polyacrylonitrile fiber, vinylon fiber, polyethylene fiber, and polypropylene fiber, with the soil. A banking with little sinking can be built even on weak ground, immediately made vegetative, and the soil generated at site can be utilized so as to form a light weight banking useful from the viewpoint of execution cost.

摘要： PURPOSE:To enable instantaneous measurement of a specific weight by incorporating the apparatus into a part of a conveyance pipe as bypassing circuit to measure a part of a fluid matter flowing through the conveyance pipe after being introduced to a subpipe part. CONSTITUTION:When a fluid matter is conveyed, opening-closing valves 7, 8 and 15 are opened while an opening-closing valve 19 and a valve as pressure withdrawing means 9 are closed. In measurement, the opening-closing valves 7 and 8 are closed to seal up a part of the fluid matter into a subpipe 3 and a vertical part 16. The valve as the pressure withdrawing means 9 is opened so that a liquid pressure is kept at an atmospheric pressure to measure the weight by volume of the fluid matter in a measuring means 11. If the pressure on the liquid is different from that on the supply side, the valve is closed by the pressure withdrawing means 9 while the opening-closing valve is opened and a pressure is adjusted by an internal pressure adjusting means 17 to reach a set pressure of a pressure setting valve 20 and then, the fluid matter in the measuring member 11 is measured. Thereafter, the valves 7 and 8 are opened while the opening-closing valve 15 is closed and the fluid matter in the subpipe part 3 is washed away. The operation is returned to the initial state.

摘要： PURPOSE:To provide a method and an apparatus for manufacture of light-weight soil for civil engineering work which does not contain a large air bubble, is high in quality and suitable especially for underwater application. CONSTITUTION:Slurry prepared by stirring by mixing viscous soil, water, and setting material in an appropriate mixer is charged into a hermetically sealed container (a cylinder 1). They are slowly mixed by stirring while a group of air bubbles generated in a bubble-generating machine 5 is being sent into the slurry of a teeming state in the container. There are a hopper 3 for charging of slurry, a discharge pipe 4 of light-weight soil, a screw 8 for transfer of slurry, and a stirring vane 9 for mixing uniformly the air bubbles into the slurry. The discharge pipe 4 rises slightly higher than the cylinder 1. Required light- weight soil can be certainly efficiently manufactured thereby.

摘要： PURPOSE:To instantaneously and positively measure the weight per unit volume of a fluid flowing within a pipe by obtaining the weight per unit volume of the fluid from the relationship between the changing values of the weight of a measuring member and the internal cubic volume thereof. CONSTITUTION:A measuring member 4 is a cylinder of a predetermined length, having one end of a flexible coupling member 3 fixed at either end thereof in the water-tight state. Each member 3 made of rubber or the like is freely shrinkable, with the other end connected in the water-tight state to a corresponding end part 2a of a cut pipe 2 via a fixed joint 8. The members 4 and 3 are suspended via a holding member 5 from two load cells 6 fixed to the upper wall of a housing 1. The changing value of the weight applied to the members is measured by the load cells 6. At the same time, the measured value is displayed directly as the weight per unit volume of the fluid running here, or operated by a processing part 7 and displayed as the weight per unit volume.

摘要： PURPOSE:To reduce a construction cost and a period by improving the soft ground along the outline of an artificial island to be constructed, and filling the earth filling material, which is composed of clay, water, cement solidifying agent and foaming agent or the like, in an area inside a protection bank constructed on the soft ground. CONSTITUTION:The submarine ground at a width of an appropriate value B is improved along the outline of a structure 4 such as an artificial island or the like to be constructed to form a foundation improvement part 1, and a protection bank 2 is constructed on the foundation improvement part 1. Next, the earth filling material, which is obtained by agitating clay, water, cement group solidifying agent, foaming agent and removal reducing agent for mixture, is filled in an earth filling part 3 of a area inside the protection bank 2. The filling work of the earth filling material is performed by feeding the earth filling material from a mixture plant of a working vessel on the sea with a mortar pump and by performing the underwater work that the earth filling material is exhausted from a lower end of a chute inserted under the water surface within the earth filling area, and an artificial island is constructed on the earth filling part 3. A load and the ground supporting force is thereby balanced to restrict ground subsidence.

摘要： PURPOSE:To prevent pollution to water and to enhance the manipulatability by discharging and underwater placing soil from a placing unit while restraining the lightweight soil from being materially segregated and dispersed with the use of a hose and a link type expander, and by discharging air from the soil above the water surface. CONSTITUTION:A hose 1 is paid out from a drum 2 on a working ship, and is connected to a lightweight soil plant 5 and is attached at its lower end with a placing unit 6, and accordingly, the soil is discharged underwater from the plant through the placing unit 6. During this period, the lower end part of the hose 1 suspending underwater is supported by a pair of link type expanders 7, 7 which are expanded and contracted in association with the operation of a cylinder device 8. Then, the hose 1 is fed at a relatively high speed, taking care of material segregation during the movement thereof. The discharge speed of the lightweight soil is gradually decreases while the soil is placed. Extra air which has been mingled into the soil during production thereof is separated from the soil at a soil discharge port, and is then discharged through an air vent port and an air blow-off port are discharged above the water surface. With this arrangement, it is possible to prevent the lightweight soil from being dispersed, and to facilitate the discharge and the storage of air and the movement of the hose 1 and the placing unit 6, thereby it is possible to enhance the manipulatability.
