摘要： PROBLEM TO BE SOLVED: To reinforce an existing underground linear structure against earthquakes by reducing the amount of shear deformation of the ground on the outer periphery of the structure during an earthquake. SOLUTION: A method of reinforcing against earthquakes an existing underground linear structure 1 installed on a base 8 and evaluated as requiring reinforcement against earthquakes when diagnosed for its earthquake resistance includes: forming ground improving parts 9 and 9 with shear rigidity equal to or greater than that of the base 8 on another base 7 on the base 8 along the longitudinal direction of the outer sides 4a and 4a of the structure 1; enhancing the shear rigidity of the ground improving parts 9 and 9 to reduce the amount of shear deformation of the base 7 on the outer periphery of the structure during earthquakes; and reducing the amount of shear deformation of the structure 1 to reduce the cross-sectional force of the structure 1 generated during an earthquake.

摘要： PROBLEM TO BE SOLVED: To provide a construction method for high banking which is excellent in executable property, high in rigidity and high in strength. SOLUTION: Pre-mixed soil compounded by mixing soil generated at a field, hardener and the like is used to bank to a required ground level. A wall surface of a bank 20 is reinforced by applying geo-textile 22 made of a woven fabric or a non-woven fabric thereto and anchoring the geo-txtile 22 by a strut 24 and an anchor rod 26 in the bank 20. According to this, reciprocal action of the hardened pre-mixed soil and the reinforcing member enhance stability and strength of the whole bank 20. Therefore, this construction method proceeds excavation work and high banking of the bank 20 at the same time.

摘要： PURPOSE:To improve the function and safety of permanent measures against groundwater for a structure set-up on the ground water-permeability, and to reduce the cost of construction therefor. CONSTITUTION:For a building 1 set-up on gravel soil 2 with water-permeability, under normal conditions, groundwater at the inside of a low-permeable layer 4 is drained outside from the gravel soil 2 by the operation of drainage 5 and a groundwater level is usually at the position lower than the level of the low- permeable layer 4 by the operation of drainage 7. In an earthquake, even if the drainage 5 function stops the low-permeable layer 4 can retard the rising of the groundwater level lowered since the layer U intercepts the rising thereof. On the other hand, even in the case where the drainage 7 function stops, the low-permeable layer 4 can similarly fulfill its function. That is, until the function of the drainage stopping is recovered, sufficient time is provided against after- shock much the same as the earthquake by operating either the drainage 5 or the drainage 7 and sufficient safety can be ensured against imaginable seismic force.

摘要： PROBLEM TO BE SOLVED: To efficiently classify and take out sand-components from the earth and sand dredged from bay coast, effluent rivers, etc., and to reduce the volume of the dredged earth and sand to be reclaimed in sedimentation basins and disposal plants. SOLUTION: The muddy water containing the dredged earth and sand is forcibly fed from a raw water introducing pipe 10 via a reduced pressure vessel 20 to a feed sump 30 and the raw water stored in the bottom of the feed sump 30 is supplied by feed pumps 30a and 30d to negative pressure liquid cyclones 50a to 50d. Granular materials of large grain sizes are separated from a slurry containing the granular materials of large grain sizes discharged from the lower parts of the respective liquid cyclones 50a to 50d are separated by an aqua- screen 70 and the desalting of the granular materials is carried out.

摘要： PROBLEM TO BE SOLVED: To construct a sturdy structure by arranging a hermetically sealed hollow structure in a cave formed in the underground and filling cement paste in gaps and pressurizing it. SOLUTION: A cave 14 larger than a structure 10 is excavated in a natural ground 12 such as bedlock, and a shaft is arranged to communicate with the top of the cave 14 and a plurality of rock bolts are installed in the cave 14. Subsequently, concrete is shot on the wall face of the cave 14 to reinforce loose zones 28 of the ground 12 caused during excavation. Thereafter, a plurality of holes are bored to reach the loose zones 28. Then, a form is installed in the cave 14 and concrete is placed to construct the structure 10. Thereafter, cement paste 40 is charged from the shaft into a space 38 between the structure 10 and the wall face of the cave 14 and the holes 30, and also into the shaft, to pressurize the paste 40 in the space 38 and the holes 30 by the weight and compress the wall face of the cave 14 and the structure 10. In this way, the loose zones can be reinforced and a prestress force is introduced in the structure to enhance the mechanical strength.

摘要： PROBLEM TO BE SOLVED: To provide an economical reclamation method by carrying out reclamation works efficiently without providing a boat carrying large equipment on board. SOLUTION: Premixed sand is placed in a sea area 30 to be reclaimed by providing a ground conveyor belt 14 on the ground 10, connecting floating conveyor belts 20, 20, 20 to the reclamation sea area 30 through a connection conveyor 16 and injecting the sand from a chute 32 for underwater placement. By providing a mixing means 34 for sand and a caking agent in the junction of every conveyor belt 20, they are mixed in the conveying process to prepare premixed sand. Conveying time of the belt conveyors is short, and thereby prevents sand and a caking agent from solidifying in the conveyance process.

摘要： PROBLEM TO BE SOLVED: To simplify an operation process and reduce the term of banking works. SOLUTION: In a breakwater 10, the surrounding area of a structure to be built is surrounded 2 with a closing sheet pile 12. After an anchor 14 is mounted 3 on the outside of the closing sheet pile 12, premixed sand 24 is filled 4 on the rear face of the closing sheet pile 12. When the premixed sand 24 solidifies and is integrated with the closing sheet pile 12 through the anchor 14, as the solidified premixed sand 24 has a high closing property, the single- layer closing sheet-pile 12 can close the surrounding area of the structure 30 completely.

摘要： PROBLEM TO BE SOLVED: To shorten the term of works required for compacting a ground by introducing groundwater, pressure of which is increased by giving impulse force from a ground surface, onto the ground through a drain column. SOLUTION: Groundwater, pressure of which is increased by giving an impulse by dropping a weight 22 such as a steel ball onto a ground to be improved 10 from the surface 12 of the ground, is introduced onto the ground through drain columns 13 installed into the ground 10, and guided onto the ground surface or the like in the periphery as the outside of the ground surface 12 through a pipe 31. The drain columns 14 can be mounted in either of before the giving of impulse force, during it or after it. Accordingly, the installation and removal of a vibrator in the ground as seen in a conventional method are made unnecessary, and the term of works required for soil improvement by the compaction of the ground can be shortened largely because the ground surface 12 is not immersed by groundwater introduced onto the ground and the period of the mounting of the drain columns 14 can also be selected in response to the properties of the ground to be improved.

摘要： PROBLEM TO BE SOLVED: To provide a small type and highly efficient classifying disposal system for a dredging earth and sand, in which a sand portion extracted from the earth and sand dredged from coastal areas and rivers is taken as a result of its classfication. SOLUTION: An aqua screen 70 as a classifying system is placed on a tank 30 with a feed sump 30. A liquid cyclone 50a to 50d and a spigot tank 60 are placed on the aqua screen 70. Compressed muddy water including a dredging earth and sand is carried from a natural water introduction tube 10 to a feed sump 30. The natural water stored at the bottom of the feed water sump 30 is supplied to a succion type liquid cyclone 50a to 50d. A large particle sized particulate body is separated from a slurry including the large particle sized large particulate body, which is discharged from below part of each liquid cyclone 50a to 50d, by the aqua screen 70, and a desalination for the particulate body is carried out.
