摘要： PROBLEM TO BE SOLVED: To provide a liquefaction prevention method of sand foundation having advantages such as guarantees for elimination of maintenance, no evilness and permanent effect. SOLUTION: Bag-shaped tubes 23 are buried in the whole ground 22 bearing a building to construct, force-fit of a self-hardening material into the bag-shaped tubes 23 is made, the density of the ground 22 is increased by the pressure and, at the same time, liquefaction is prevented by increasing effective stress in the ground 22. Liquefaction is prevented by decreasing shear strain from soil improvement effect caused by solidified material in the bag-shaped tubes 23.

摘要： PURPOSE:To utilize the core material of a soil cement column line wall as part of the permanent underground wall of a synthetic underground skeleton. CONSTITUTION:A short threaded bolt 3 is fitted by welding on the inside face of the core material 2 of an underground wall in advance, and a protective cap 4 is fitted to the bolt 3. After the construction of a soil cement column line wall 1 is completed, soil cement is removed to the inside face of the core material 2. The protective cap 4 of the threaded bolt 3 is removed, and a threaded connector 5 is screwed to the threaded bolt 3 via a joint coupler 6. Horizontal/vertical bars 7 are arranged in an underground wall portion, a formwork 8 is installed at the inner position of the underground wall, and concrete 9 is placed. Since the short threaded bolt 3 is fitted to the core material 2 in advance, the execution quality of the weld portion is improved, a large- diameter connector can be employed via the joint coupler 6, and this contributes to the construction of the soil cement column line synthetic underground wall having high execution property and reliability.

摘要： PURPOSE:To measure the displacement of a pipe line highly accurately by coupling a traveling body being hauled by a cable with an inertial sensor through a bendable coupling so that the inertial sensor is not affected in the hauling direction of cable. CONSTITUTION:A bendable rope 22 couples the central part B at the rear end of a body 18 having wheels 20 and running through a pipe line 10 with the central part A at the front end of a casing 14 having wheels 16 and covering an inertial sensor 12. A hauling cable 26, having one end fixed to the front end of the traveling body 18, is wound around a cable winding reel 24 on the outside of outlet 10B of the pipe line 10. Since the sensor 12 is run from an inlet 10A to the vicinity of the outlet 10B in order to calculate the displacement of the pipe line from a reference position at the time of embedment thereof, the cable 26 sags at the time of hauling to exert downward force F1 to the traveling body 18. The traveling body 18 thereby travels while inclining forward but the inclination angle theta1 of the rope 22 with respect to the axis 10c is negligible when compared with the inclination angle theta0 of the cable 26. Consequently, the sensor 12 does not incline but runs along the profile of pipe line and measures the displacement accurately.

摘要： PURPOSE:To excavate a deep shaft by means of a self-standing retaining wall of solidified ground. CONSTITUTION:The ground is improved to form a solidified ground 4 in the range of a ring-shaped form (compression ring effect) up to the thickness showing the strength of a self-standing retaining wall in which the ground can the excavated regarding as the plane direction of the external peripheral ground in the excavating area, and in the range of the same depth with at least the excavated depth of the shaft from the ground level regarding as the vertical direction. After the solidified ground 4 has become rigid, the solidified ground is excavated by making use of the solidity to form a shaft 3. The peripheral ground of the excavating area is solidified to form a cylindrical or conical shape and the shaft 3 is excavated by an extremely deep level by use of the self-standing retaining walls. And hence, it can be carried out with less temporary construction and low cost and further, in a reduced period.

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 permit various shapes of piles to be removed out by cutting off an existing pile buried by a cutting blade provided to an oil-pressure grab bucket. CONSTITUTION:A trench 12 is excavated in a place where an existing pile is to be removed out by means of an oil-pressure grab bucket 4 having a cutting blade 8 on the inside of its excavating blade 6. After a pile 9 is reached, the bucket 4 is opened and closed to repeat cutting operations by the cutting blade 8. The removing speed of the pile 9 can thus be quickened and the pile 9 can be cut off even when the pile 9 is bent and also by avoiding the coupler metal even when engrafted piles are present.

摘要： PURPOSE:To enable the tendency of an error in a boring accuracy to be grasped in the course of boring by once stopping the boring in the course of a boring process for a soil rod line, measuring the quantity of the deformation of a measuring pile by a clinometer and arithmetically processing the deformation curve of a rod. CONSTITUTION:One measuring pipe 1 is provided in the central portion of four rods 3... that are driven in rotation by an auger machine 10 and elevated and lowered along the leader 7 of a crawler 9. The pipe 1 is fixedly mounted to connecting plates 2 and 2 in a position parallel to the rods 3... and in the same manner as the rods 3.... A roller type clinometer 4 is inserted into the pipe 1 from its top opening and elevated and lowered between the top and bottom of the pipe 1. The clinometer 4 is of a differential transformer type and suspended by a cable 17 for taking out a measuring output therethrough, being manually or mechanically elevated and lowered. The clinometer 4 measures the inclination of the pipe 1, for example, at every approximately 1m pitch point. The cable 17 is connected to an arithmetic unit 8 and inputs the measuring output thereto. A boring accuracy is obtained by an arithmetic processing based on the measuring output of the clinometer 4.
