摘要： PROBLEM TO BE SOLVED: To improve workability by supporting the front and rear parts of a base frame by wheels through a supporting frame and making it possible to finely slide the wheels in the axial direction and also change the direction. SOLUTION: When equipping attaching/detaching unit A, Aa for wheels, after the whole device has been supported by outriggers 7, the units A, Aa are fixed to a base frame 1 by respective attaching/detaching arms 15, 15a. Then, the outrigger 7 are contracted and the device is supported by the wheels 14, 14a. Then, the device is transferred to the press-in position of the casing by controlling the steering wheel 28a while dragging a traction rod 31 by a self-propelled vehicle and the forward and rearward position is adjusted. The front and rear support frames 12 for the wheels are infinitesimally and synchronously moved to the right or the left for fine adjustment of the right and left direction of the press-in position. Then, the outrigger 7 is grounded and the units A, Aa are removed from the frame 1 to secure a wide working space. Thereafter, the casing C is held by a chuck 5 and pressed in while rotating. In this way, the device can be easily transferred and the position can be finely adjusted.

摘要： PROBLEM TO BE SOLVED: To prevent erosion as a bulkhead wall at the time of flood without obstructing a natural environment, a landscape and a natural system by continuously burying underground walls composed of permeable concrete at a prescribed interval from the natural slope face of a river. SOLUTION: Underground walls 1 are continuously buried along a river 3 toward the underground from positions separated at prescribed distances from the slope shoulder 2a of the natural slope face 2 of the river 3. A permeable concrete plate or a sheet pile is used for the underground wall 1, projection and recess parts formed on sides are fitted and continuously successively positioned, and deeply inserted from a river bed 3a to sufficiently secure depth of embedment L so as not to expose the upper part on the ground. However, a panel-like box sheet pile as the inside is made hollow may be used. Thereby because the underground wall 1 is not exposed on the ground, a natural landscape is not damaged, and in addition, underground water freely moves not to obstruct a natural system. In the case of flood, the underground wall 1 is a bulkhead, so further erosion is prevented even if the natural slope face 2 is flowed out, and the natural shape face 2 after flood is restored by earth covering.

摘要： PROBLEM TO BE SOLVED: To continuously perform lateral excavation of a ground and backfilling of the lateral excavated sand and soil by carrying out excavated soil and sand from a rearward excavation hole while the ground is laterally excavated, and performing backfilling after the excavated soil and sand is mixed with a ground improvement chemical. SOLUTION: After one stroke drive of a lateral drive cylinder while lateral excavation by an excavation screw rod 42, transportation for the mixing box 37 of the lateral excavated soil and sand, mixing and stirring of the excavated soil and sand and cement milk by the screw rod 42a and downward backfilling are continued, a self running carriage is advanced in the same direction as lateral excavation only up to the equivalent distance of one stroke length of the cylinder while the cylinder is extended and driven. The lateral excavation of both screw rods 42, 42a by reduction drive of a lateral drive cylinder is restarted as the above. The lateral excavation of a one-stroke part is intermittently repeated to continue ground improvement in a wide range.

摘要： PURPOSE:To disperse an excavation load in the case an egg-shaped pipe is buried by positioning a main excavation head of the front end of an auger on the axis of a cutting edge pipe, and positioning an auxiliary excavation head on the front end of an inverted egg-shaped section of a guiding pipe, and excavating a hole nearly alike to the section of the egg-shaped pipe. CONSTITUTION:A driving section 4 is retreated, an egg-shaped pipe 1 is set to a pipe receiving section 7 in the shape of an inverted egg, and when a cutting edge pipe 9 is directed in the ground to rotate and drive a screw auger 13, the ground of the front end of the cutting edge pipe 9 is excavated with a main excavation head 14. After that, when an auxiliary excavation head 18 reaches the ground excavation surface, the lower part of an circular hole is excavated to insert an egg-shaped pipe 1 thereinto. Then, the driving section 7 is advanced with a driving cylinder 6, and the egg-shaped pipe 1 is buried into the ground. After one of the egg-shaped pipes 1 is pushed into, the driving section 4 is retreated again, and a new egg-shaped pipe 1 is suspended and added to bury. According to the constitution, the egg-shaped pipe 1 can be automatically buried.
