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： PROBLEM TO BE SOLVED: To continuously and stably treate dredged sludge by adding a filler material to the sludge in a passage, filtering and draining the moisture in the sludge from the passage in a water separating part, then adding a solidifying material to the sludge and transporting the resulting sludge to a disposing place. SOLUTION: A dredged sludge is transported in a pipeline, a filler material is added thereto in a filler material adding and kneading part 10, and the resulting sludge is stirred by a stirring blade 12 while it is sent by a screw blade 11. The sludge is then carried to a water separating part, wherein the moisture is filtered and drained through the wall surface of a filter inner pipe 21 by a suction pump 23B. The sludge is sent to a sludge content measuring part 30 to measure the sludge content by a load detector 35. The flow rate of the sludge is measured by an electromagnetic flowmeter 40. Further, the sludge is carried to a solidifying material adding and kneading part 50, a proper quantity of a solidifying material 56 such as cement is added thereto on the basis of the sludge content and flow rate, and the resulting sludge is stirred by a stirring blade 52 while it is carried by a screw blade 51, and transmitted to a disposing place 60.

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 reduce the total weight of civil engineering construction such as a banking, rock shed and snow shed, provide sufficient strength and rigidity, prevent settlement collapse and deformation breakage, and absorb and reduce a gravity load and an impact load due to slipping down rocks. CONSTITUTION:Lightweight blocks 3, 3... each having a trapezoidal cross section and specified thickness are laminated in a random masonry shape with specific voids on a roof 2' being a base of a rock shed 7, and a wearing course thereof is covered with solidification processed soil 4 so as to have shape retainability of the whole. The weight is reduced as a whole by means of a lightweight block rock shed as a civil engineering construction on the roof 2' of rock shed 7, the solidification processed soil 4 and void filling among lightweight blocks 3. An impact load due to slipping down rocks and the like is absorbed and reduced by voids among respective lightweight blocks so as to surely retain a fundamental function of the rock shed 7. Since the lightweight blocks can be mass-produced, the cost is reduced, workability is excellent and there is no fear of environmental pollution problem when they are discarded for re-construction.

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.
