摘要： PROBLEM TO BE SOLVED: To conduct a low pollution vegetation by placing high moisture content clay into a cloth bag body, bagging and dehydrating the high moisture content clay, and producing the bag body with noncorrosion fiber of synthetic fiber and corrosion fiber such as regenerated fiber formed into a mesh. SOLUTION: Materials of warp 11 and weft 12 are to be noncrossion polyester fiber filament yarn 13 or the like and rayon fiber filament yarn 14 or the like as corrosion material formed into a mesh. In this instance, the material is of being corrosive in three months or longer and twelve months or shorter, and a mesh structure is employed for avoiding mud escaping generated in a dehydration process and being in accordance with the growth of plants. Also, the yarn forming a bagging dehydration bag 10 is made into a mesh structure having a width of 1mm or more. Thus, a corrosion of a great part of the bag body makes an environmental pollution less, and further an interlocking effect causes it to be integrated with soil at the place of disposition. In this manner, any slippage is not likely to take place on the disposition surface, so that the ground can be rendered stably.

摘要： PURPOSE:To prevent the collapse of a slope by boring holes in the approximately horizontal direction from the surface of the earth of the slope up to specific depth with a boring machine, and inserting impermeable or semipermeable membranous bodies in the holes. CONSTITUTION:Boring trenches are formed in the ground in the approximately horizontal direction from the surface of the earth up to specific depth in a natural bedrock and a cutting natural bedrock S. After that, boring bodies are pulled out, and impermeable or semipermeable membranous bodies 1 are buried over a plurality of up and down stages. Thus, rain water permeated from the surface of the earth is cut off by the membranous bodies 1 so that it permeates no further depth mentioned above. Percolating water cut off by the membranous bodies 1 is led to the surface of the earth and is discharged. According to the constitution, the permeation of rain water, etc., is prevented or decreased and, at the same time, the bedrock can be reinforced to prevent the collapse of the bedrock effectively.

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 excavate a tunnel having a required sectional form with high degree of accuracy by controlling a revolving locus of a planet cutter by turning against a rotator of a turning member bearing the planet cutter. CONSTITUTION:A rotating angular amount of a cutting wheel from a reference angle is detected by a cutting wheel rotating angle detector 38. displacement of a lever bearing a planet cutter from a reference position as an expansive amount of a hydraulic cylinder is detected by a hydraulic cylinder stroke detector 39. A feedback control signal setting section 42 is provided, feedback control is made based on variations between target values of displacement of the lever corresponding to the rotating angle of the cutting wheel and actual displacement. In addition, a feed forward control signal setting section 43 is provided, feed forward control is made based on the difference between the target value in the current time and the target value in the time increasing the rotating angle of the cutting wheel by the angle set in advance from the current time.

摘要： PURPOSE:To stabilize banking by a method wherein a block body containing a plurality of container form pieces having rigidity and a light filler between the pieces forms a banking body, and the banking bodies are laminated in a state to be densely filled in an adjoining state. CONSTITUTION:A brick-form block body 6 is formed such that a bag body 7, e.g. polyvinyl chloride, is previously filled with bubble mortar 9, being a light filler, filled with a piece group, e.g. spent empty cans 8, empty bottles 8', packs 8', and incinerated refuse 8'' and the inlet of the bag body 7 is closed. The pieces 8, 8', and 8'' perform a function as a bubbleform gap forming member and aggregates for the block body 6, and serve to reduce the weight of banking and increase rigidity. A group of the block bodies 6 is laminated on a banking body 3 on a soft ground 2, covering with a press material 5, e.g. geotextile, is effected, and a covering layer 4 is laid to form banking 1. This method prevents the occurrence of a lateral slip owing to an on-bank load and stabilizes the banking.

摘要： PURPOSE:To shorten construction period, and also to obtain a coping having a wave dissipation function by putting a cushion material on the top end of a steel sheet pile wall, and thereon placing a prefabricated coping of various shapes, and by fixing it to the steel sheet-pile wall via an arbitrary fixing member. CONSTITUTION:On the top end of a steel sheet-pile wall 1, a rubber cushion material 2 of approximately 30 to 100mm thick is set, and on this cushion material 2, a prefabricated coping 3 of a staircase shape stretched out toward the water region is placed. And the prefabricated coping 3 is fixed to a leveling channel 4 that has been welded to the rear upper end of the steel sheet-pile wall 1, and to the front upper end of the steel sheet-pile wall 1 by means of bolts 5. Thus, labor of formwork can be saved, and construction work can be enabled independently of the water level in front, so that construction period can be shortened, and a prefabricated coping 3 having various functions can be constructed.

摘要： PURPOSE:To carry out soil with high efficiency by providing a small-diameter cutter to the periphery of a cutter plate rotatably set on the front end opening of an excavator and also by providing an injecting port through which mud is jetted from the back side to the front side of the cutter. CONSTITUTION:When motors 13 and 16 for rotationally driving a cutter plate 3 and a small-diameter cutter 9 are operated, the plate 3 is turned to excavate the ground. The cutter 9 also turns with a greater turning number than that of the plate 3 around the central shaft of the plate 3 to excavate the ground while agitating soil. When supplying mud to mud pathways 26a - 26c provided in the central shaft 4 of the plate 3 during the excavation period, the mud is jetted toward the ground from injecting ports 11 and 12. The excavated soil mixed with the mud uniformly by the cutter 9 is directed into a soil intake chamber 35 and discharged by a screw conveyer 36.
