摘要： PURPOSE:To increase a point bearing power, and reduce construction cost by intruding compaction piles into the tip ground through guide pipes, and recovering excess length parts of the guide pipes after cement milk and the like are filled. CONSTITUTION:Guide pipes 2 and 2, which are formed by connecting effective length parts 2a and 2a and excess length parts 2b and 2b to each other through joints 5 and 5 so as to be connected/disconnected, are arranged in an excavation hole 1. Next, concrete 3 is placed from the bottom part of the excavation hole 1 to a bottom part position under a building, and is cured. Next, after it is cured, compaction piles 6 are intruded into the tip ground 10 through the guide pipes 2, and afterwards, cement milk 4 and 4 and so on are filled at least up to the effective length parts 2a. In succession, the excess length parts 2b of the guide pipes 2 are cut off in positions of the joints 5, and are recovered.

摘要： PURPOSE:To prevent the desolation of the point ground or the deterioration of the fill cement milk by mounting a cover plate provided with cut grooves formed in a radial shape from the center section to the front end of a guide pipe, cutting off the front end in a state of watertightness and, at the same time, breaking the cover plate with a compaction pile. CONSTITUTION:An opening section of the front end of a guide pipe 1 is cut off with a cover plate 2 of a steel plate in a state of watertightness. Then, a large number of cut grooves 5 are arranged in a radial shape from the center section to form them on the cover plate 2. A compaction pile 4 is lowered into the guide pipe 1 attained to the point ground 6, and it is driven while breaking the cover plate 2. After that, the guide pipe 1 is filled with the fill cement milk 13. According to the constitution, a back current of excavate muddy-water is prevented with the cover plate 2 or a breaking piece 12, the desolation of the point ground 6 or the deterioration of the fill cement milk 13 is prevented, and it can be effective for the increase of bearing power by compaction of the point ground 6.

摘要： PURPOSE:To perform a measurement with high accuracy by a method wherein at least one conduit element whose bend data is known and which is rigid is provided, other conduit elements are connected and the bends of the conduit elements are compared with the known bend of the rigid conduit element. CONSTITUTION:Flange parts F1 to F5 are constituted in such a way that their wall thickness is thick and that they are not buckled or the like. Consequently, when an outside pipe OP is deformed due to the influence of the subsidence or the like of the ground, its deformation is transferred as it is as the deformation of individual connecting pipes C1 to C5 corresponding to the individual flange parts F1 to F5. Since individual conduit elements P1 to P4 are held in a state that they are levitated inside the outside pipe OP, the individual conduit elements P1 to P4 are not bent even when the ground 10 subsides. Then, regarding the conduit elements P1 to P4 whose bend data is known and which are rigid, a gyro drift during a measurement traveling operation is determined by comparing a measured angular output in the travel of an inertia sensor 12 with the known bend data of the rigid conduit elements, and measured data is corrected.

摘要： PROBLEM TO BE SOLVED: To provide a vertical loading testing method of the directly under ground confirming availability of the directly under ground of a structure without pulling down a foundation of the existing structure.
SOLUTION: A part of a foundation slab coming into contact with the ground surface of the existing structure is separated from the peripheral part in a predetermined size and shape to form a loading slab. A loading testing jack together with a load meter and a displacement meter are installed on the loading slab in an approximately vertical posture to have such a constitution that loading test reaction force is taken in a beam of the existing structure or a slab, and the jack is driven to perform a loading test. After the completion of the loading test, the loading slab is removed to restore the foundation slab, alternatively the loading slab is again combined with the foundation slab to restore the foundation slab.

摘要： PURPOSE:To obtain an artificial ground which can be easily constructed at low cost and in a short period. CONSTITUTION:A PC pile 11 is used for piling. A reinforced concrete post 12 covered with a steel cylinder 12b with a fitting part of beams at the upper part thereof is used as a post. The piles 11 are driven respectively in a number of post positions of an artificial ground. The lower part of the posts 12 is jointed to the upper part of the piles during the driving piles so that the upper ends of respective posts 12 are arranged at a specified level. The ends of respective steel-framed beams 13 are connected to the fitting parts of beams 12b1 12b2, 12b3, of respective posts. PC floor plates 15 are placed on the upper side of respective steel-framed beams 13 and reinforcing rods R3 for the slab are arranged on the upper side of the PC floor plates 15. Concrete C1 is placed at the upper side of the PC floor plates to form a slab 16 made of reinforcing concrete and also concrete is placed in the hollow spaces h3 of respective posts. In this way, forms, supports, etc., are not required and hence, the construction period is reduced.

摘要： PURPOSE:To shorten drilling construction period due to thin wall thickness, reduce industrial waste due to decrease of a drilled soil quantity, and increase the effective floor area of an underground floor part by a decrease in the wall thickness, by making the wall thickness less than a fourth or fifth in comparison with a customary RC continuous underground wall, in the case of large depth (deeper than 30m in depth of the basic bottom). CONSTITUTION:A plurality of steel framed members 2 spacedly arranged in the lengthwise direction of an underground wall 1 are extendingly provided in the vertical direction in the underground wall, and the respective steel framed members 2 are joined with the respective points of intersection of a plurality of lateral connecting materials 3 arranged in the lengthwise direction (horizontal direction) of the underground wall 1 spacedly in the vertical direction on both outside of the members 2. Longitudinal lateral reinforcements 4 for a wall are provided outside the lateral connecting materials 3, the steel frames and reinforcement are inserted into the groove 6 for a wall drilled in the ground, and concrete 5 is placed therein so as to make them into one body.

摘要： PURPOSE:To detect the soundness of a pile, the existence of slime in the forward end of the pile and the length of the pile and so on by reading an impulse wave transmitted from an impulse wave sending device buried in the pile through the pile by a sensor. CONSTITUTION:A pile hole 10 is formed in a designated position of a ground 13 to be used as a foundation of a building by digging, and a reinforcement cage A is inserted in the pile hole 10. Before the reinforcement cage A is inserted in the pile hole 10, an ultrasonic wave transmitter 15 is fixed at an intersecting portion of supporting rods A1 disposed like a cross, and the respective end portions of the supporting rods A1 are fixed to reinforcements A2 forming the reinforcement cage A in such a manner that the ultrasonic wave transmitter 15 is positioned on the central axis in the longitudinal direction of the reinforcement cage A or in its vicinity. The ultrasonic wave transmitter 15 and a power supply B on the ground are connected by a cable C. After the reinforcement cage A is inserted in the pile hole 10, ready-mixed concrete is placed, and a sensor 17 is disposed in contact with the surface 11a of the pile head and connected to a monitor 18.
