摘要： PROBLEM TO BE SOLVED: To prevent deterioration of structure characteristic by normal quality control by sequentially applying adding driving operation by means of drive relaying part arranged in the inner surface direction so that the drive relaying parts continously arranged in the inner surface direction of underground outer wall or a projecting part in the outer surface direction, etc., are connected. SOLUTION: A first drive part 1 is formed by placing connect by use of a drive relaying form 1' having a protrusion 1a or a recess continously extending in the inner surface direction of underground outer wall so as to transmit in-surface shearing force to a lower part of underground 1st floor, and a projection 1b or recess connecting the projecton 1a or the above recess extending in the outer surface of the underground outer wall, at a bottom form of a first drive part 1 constructing perpendicularly suspended concrete at the underground 1st floor. Then, after the construction of underground 1st floor slab 3, the form 1' is disassembled and a post drive part 4 is constructed on the slab 3 to form a drive relaying part. The drive relay form 1' is used to apply addition drive of structure downward in order. Accordingly, even if sinking is generated after the placement of concrete, no gap is generated between the first drive part 1 and the post drive part 4.

摘要： PURPOSE:To relieve a burden on an operator, to save man-power and to promote work efficiency by automating rising and falling of an excavating bucket, opening and shutting of a clamshell, correction of the inclination of the excavating bucket and chopping operation. CONSTITUTION:Various kinds of buttons on an excavating control panel 53 are manually controlled to raise and lower an excavating bucket 23 and, at the same time, a hydraulic jack 236 is opened and shut to excavate a continuous wall 19. Then, after the depth of the continuous wall 19 is so excavated that the depth thereof reaches the depth enough to bury the whole excavating bucket 23, an excavation mode is changed to an automatic mode from a manual mode. With rising and falling of the excavating bucket 23, an excavation of the ground is automatically carried out based on data from a rising and falling amount detector 32 and a load detector 30. An output signal of an inclination detector 31 is taken in an arithmetic processor 42, and an inclination is obtained to perform an inclination correction routine. In addition, sufficient quantity of excavation is determined based on data from the load detector 30 in case an ground excavation is carried out by shutting operation of a clamshell 235 and data from the rising and falling amount detector 32, and the excavating bucket 23 is raised to remove the earth.
