摘要： PURPOSE:To improve safety by interposing a push-down hydraulic jack between the lower surface of a reaction force frame iron beam and a huge span beam, and removing the push-down jack etc., after a preceeding load becomes zero due to the transfer completion of a given superimposed load to on the span beam. CONSTITUTION:The upper parts of reaction force frame iron columns 4 and 4, standing from a foundation part between feet bases 2 and 2 while sandwiching a huge span beam 3 erected between the feet bases 2 and 2, are jointed with reaction force frame iron beams 5, a push-down hydraulic jack 6 is interposed between the reaction force frame iron beams 5 and the huge span beam 3, and the huge span beam 3 is forcedly deformed. Next the push-down hydraulic jack 6, fraction force frame iron columns 4, and reaction force frame iron beams 5 etc., are removed after the transfer completion of a given superimposed load to the huge span beam 3. Then the hydraulic jack 6 is locked after the huge span beam 3 is forcedly deformed in a vertical direction to be made level.

摘要： PROBLEM TO BE SOLVED: To omit driving piles penetrating an old foundation and increase the degree of freedom in design and reduce the construction cost of a building, by filling a mixture of demolished debris and mortar in the underground structure of an old building to construct a bearing ground for a new building. SOLUTION: A double-slab or a double-wall of a structure A2 on the ground and an underground structure A1 of an old building A are demolished, and a part of the demolished debris G1 are dropped into the underground structure A1 by making use of an elevator shaft or a duct space. Mortar G1 is charged in the voids in a pit and agitated by a back hoe to uniformized them and obtain a filler G. The forgoing processes are repeated down to the bottom face position of a new building B to form a bearing ground H. After the bearing ground has been cured, the underground structure B1 and the structure B2 on the ground of the new building are erected in sequence. A foundation structure 13 is formed at the lowermost part of the underground structure B1 and connected to other underground structures B1 through a plurality of base isolation devices D. Since bearing piles penetrating the old foundation are not required, the degree of freedom in design is large and the construction cost can be reduced.

摘要： PURPOSE:To make safe and easy execution of work feasible and to reduce construction cost sharply by boring horizontal and diagonal bores in pipe-like bodies erected in the ground, and by constructing a truss-like network of these bores and the pipe-like bodies filled with liquid type solidifying material. CONSTITUTION:A number of pipe-like bodies 4 and 4 having windows 6 at the depth the same as the stratum of a hard clay layer 5 are erected in the ground 1. Then horizontal bores 9 and slant bores 10 are bored by means of water jet 8 from the windows 6 of the pipe-like bodies 4 and 4 in the horizontal and the diagonal directions until the bores reach the adjoining pipe-like bodies 4 and 4. The bores 9 and 10 and the pipe-like bodies 4 and 4 are then filled with liquid type solidifying material 11 and the material is made to solidify, and a truss-like network 12 is constructed thereby. When the ground is a water permeable type without the head clay layer 5, expandable synthetic resin is injected into the ground 1 after solidification of the truss-like network 12. Then the ground 1 at the underside of the truss-like network 12 is excavated and a desired underground space 14 is constructed after discharging excavated soil through a vertical shaft 13.

摘要： PURPOSE:To prevent the occurrence of a cracking in the soil in case of grouting of cement milk by providing a pressure cell and a gravel chamber to the lower end of a reinforced cage and providing a covering with high permeability to the circumferential wall of the gravel chamber and the bottom wall. CONSTITUTION:A reinforced cage is so constituted that a pressure cell 5 is provided to the lower end thereof, a grout pipe capable of grouting from the ground is provided and a gravel chamber 4 is provided to the pressure cell 5. The circumferential sides and bottom of the gravel chamber 4 are surrounded by a synthetic fiber covering 17 with high strength of the coefficient of permeability, 1.0X10 - 10X10 cm/sec. The reinforced cage is inserted into a boring bored to the soil, and cement milk is forced to the inside of the gravel chamber 4 to harden after placing concrete by using a tremie pipe. According to the constitution, the occurrence of a cracking in the soil caused by grouting of cement milk can be prevented, and the soil and the chamber can be integrated.

摘要： PROBLEM TO BE SOLVED: To quicken the rebuilding and to exhibit the freedom degree in design of a new building by forming a bottom plate structural part and an underground structural part of a new building on a support ground for the new building formed by filling filler in the underground structure of an old building, while demolishing the old building. SOLUTION: A ground structural part A2 is demolished from the upper layer, the underground structural part A1 is demolished from double slabs and double walls to unite a space, parts of demolished concrete pieces G1 are dropped in the underground structural part A1 through a vertical hole part 4 such as an elevator shaft and a duct space to fill a pit part 9, and voids in the pit part 9 are filled with mortar G2, agitated, and integrated together. The demolished concrete pieces G1 and the mortar G2 are filled there till the bottom base position of a new building B and are agitated to form a support ground H so that the underground structural part B1 and the ground structural part B2 of a new building B are erected after curing. This structure can quicken the rebuilding work, execute the planning without considering the column positions of the old building A, and exhibit the free design of the new building B.

摘要： PROBLEM TO BE SOLVED: To improve stability of an earth retaining frame, and shorten a construction period by constructing a floor and a bean of a column base footing above a footing beam constructed on an excavating bottom surface after an earth retaining wall and a structural center column are constructed, and supporting the center column by a base isolation device by cutting it off in a part of a base isolation layer after a building upper load is supported by timbering. SOLUTION: After an earth retaining wall 1 and a structural center column 2 are constructed underground, a first story floor 4 and a beam 5 are constructed on a ground surface level. The, secondary excavation is performed, and a process to construct an underground first story floor 4' and a bean 5' is repeated, and a footing beam 7 is constructed on an excavating bottom surface in the stage when the ground is excavated up to the final excavating level. A floor 8 and a beam being a column base footing are constructed above the footing beam 7, and a base isolation layer 10 is formed between it and the footing beam 7. After an underground outer wall 13 and an underground story column 14 of a building are constructed in this stage, the building is supported by timbering 11 arranged between the footing beam 7 and a column base footing beam, and among the column 2, a part exposed to the base isolation layer 10 is cut off, and a base isolation device 12 is installed, and the timbering 11 is removed, and is replaced with support by the base isolation device 12.
