摘要： PURPOSE:To stabilize a slope, and to prevent the breaking of a bedrock positively by obviating the generation of a sliding surface at the deep place of the bedrock containing soft rock or inhibiting stress release. CONSTITUTION:The structure of a cut slope contains retaining walls 14 at multistages mounted into a bedrock 12 comprising soft rock vertically or approximately vertically from the slope of the bedrock 12 and fixed onto the bedrock by a plurality of anchor members 16 and small stages 18 formed among the mutual retaining walls by cutting the bedrock. The cut slope 10 is constructed by successively carrying out a process including the installation of the vertical or approximately vertical retaining walls 14 into the bedrock 12, fixing onto the bedrock 12 by the anchor members 16 of the retaining walls 14 and the formation of the small stages 18 by cutting parts of the bedrock 12 on the valley sides of the retaining walls 14 toward a lower section from the upper section of the bedrock 12.

摘要： PROBLEM TO BE SOLVED: To effectively and economically manufacture large boxes to be sunk and sink them in water by manufacturing the RC structure type sunk boxes with a specified length, on a semi-submerged type barge, then performing the fitting-out thereto, thereafter launching the barge for putting the boxes in water, and floating them again. SOLUTION: A semi-submerged type barge 1 equipped with a plurality of water tank chambers 1S therein and balast tanks 3, 3 on both right and left sides 1e thereof is moored to a shore wall near a site for sinking, and sunk box production equipment is installed therein. On a deck of the barge 1 sand is layed, while controlling the inclination of the barge 1 by charging water to the chambers 1S and tank 3 and discharging water therefrom, blocks 2a of RC structure type sunk boxes 2 are connected to have a length of 100 m or more toward the front part 1f and the rear part 1b. After the finished sunk boxes are applied with specified fitting-out, the production equipment of the barge 1 is removed, and the barge 1 is moved to a water region of a specified depth. Then, the tanks 3 are charged with water for bringing the barge 1 into a semi-submerged condition, and the sunk boxes 2 are moved from the front part 1f and put in water so that they are pulled to the site for sinking them. The water in the tanks 3 are then discharged to float the barge 1 on water.

摘要： PROBLEM TO BE SOLVED: To remove slime from a stable liquid without being substituted with a good liquid. SOLUTION: Just after the ground is excavated, a sand content rate of a stable liquid 12 in a groove 10 is about 4 to 6%, but a bentonite particle swelling in the stable liquid 12 loses a swelling function by adding a deflocculant, and since an earth particle sticking to the bentonite particle is separated, slime S naturally precipitates in the groove bottom without floating. The swelling function of the bentonite particle temperarily reduces by adding the defloculant, but since an excellent permeating depositing layer and a muddy film are formed on a groove wall 16, stability of the groove wall 16 is secured by fluid pressure of the stable liquid 12, and a collapse of the groove wall 16 is prevented.

摘要： PROBLEM TO BE SOLVED: To increase work efficiency by exploding an explosive provided in bottom parts of a plurality of holes which are drilled up to the vicinity of a depth at which a pneumatic caisson is to be sunk to generate a crack and digging the ground manually or using a machine in a work room in a bottom part of the caisson. SOLUTION: First, a plurality of holes 16 which extend from a surface 14 of the ground to the inside of a rock-bed 10 are drilled. After generating a crack in the rock-bed 10, the ground is digged manually or by using a machine in a work room 20, and sand and earth which are digged up are removed to sink a caisson 12 down to a depth at which it is to be sunk in the ground. The supply of pressurizing air in the work room 20 and the removal of the sand and earth which are digged up are done through a pipe and a shaft. After drilling a predetermined number of holes 16, an explosive 26 is charged into a bottom part to explode it continuously or simultaneously to generate many cracks in the rock-bed 10. A pipe made of vinyl chloride may be inserted into each hole 16 to prevent a washout of a hole wall. Consequently, it is possible to make pressure in the caisson 12 equal to atmospheric pressure when the caisson 12 is sunk so as to improve work efficiency.

摘要： PROBLEM TO BE SOLVED: To reduce the dispersion of reinforcing effects, by distributing three- dimensionally lattice-form net pieces including a binder into soil. SOLUTION: Monofilaments or multifilaments of synthetic fiber or chemical fiber are twisted to make twisted threads. A thready material 18 obtained as nontwisted threads is shaped to form a mesh and a lattice-form small net piece 14 is formed. These small net pieces 14 and a binder like cement are added to soil 12 and mixed together by a mixer to distribute three-dimensionally the small net pieces 14 into the soil and laid in the ground to form a reinforcing bed. When the binder is cured, soil 12 particles are connected to the thready material 18 of the small net pieces 14 by the bonding force of the binder. The bonded parts 13 of the soil particles are positioned so as to surround the thready material 18 of the small net pieces 14 and distributed together with the thready material 18 in the soil 12.

摘要： PURPOSE: To improve the discharge performance of excess water and the filter performance by forming clearances between a plate and a front structure of woven fabric. CONSTITUTION: A sheathing board 10 for a form for molding concrete includes a plate 12 having a square plane shape as a whole and a double-woven fabric 14 attached to the plate 12 in such a state as covering the surface 12a of the plate 12. The plate 12 has a lot of holes 16 opened in its surface 12a and its rear face. The double-woven fabric 14 allows water to pass through and has a front structure stopping the passing of concrete and a rear structure opposed to the surface 12a of the plate 12 and relatively displaced to the surface 12a. The rear structure functions as a spacer regulating a plurality of spaces formed between the front structure and the plate 12.
