摘要： PROBLEM TO BE SOLVED: To contrive to enhance excavation accuracy and further improve an earth removal function when constructing an underground continuous wall. SOLUTION: An excavation ditch B is preliminarily formed on both sides of the ground to be excavated. A reaction force material 10 and an excavation guide material 11 having a sludge pipe 12 are erected in the excavation ditch on both sides. An excavating machine A is arranged to be inserted into the excavation ditch on one side with a lift means using the excavation guide material as a guide. When the excavation machine A arrives at a specified widening excavation section, the excavation machine A is adapted to come to a halt. An equipped excavation means is turned and sent to the ground side to be excavated where excavation starts with the excavation means. While excavating and turning, the excavation machine A is transferred and adapted to execute widening excavation up to an angle so that the excavated earth and sand may drop spontaneously to the excavation ditch side (the release side). With the excavation means holding the aforesaid angle, the excavation machine A is moved at first to a natural ground in the upper part (the ground to be excavated) and wideningly excavated.

摘要： PROBLEM TO BE SOLVED: To drive an underwater steel-pipe-sheet pile at low cost in a short period. SOLUTION: The primary driving of steel-pipe-sheet piles 19 is conducted by a vibro-pile driver 17 hung down from a crane in conformity with piles for an introducing material installed on a water-bottom bearing ground, and secondary driving is performed by the following execution procedure. An internally inserted pipe 10, on which a piping for a water jet is mounted, is connected to the vibro-pile driver 17 hung down from the crane, and inserted into the steel-pipe-sheet piles 19 after primary driving and the piles 19 are struck and lowered. The driving of the internally inserted pipe 10 is stopped, the vibro-pile driver 17 and the water jet are used jointly and the internally inserted pipe 10 is sunk by itself up to the upper ends of the steel-pipe-sheet piles 19. The internally inserted pipe 10 and the steel-pipe-sheet piles 19 are gripped by the gripping means of the vibro-pile driver 17. The vibro-pile driver 17 and the water jet are used in combination, and the sheet piles 19 are driven into water up to specified places. The driving of the internally inserted pipe 10 and the steel-pipe-sheet piles 19 are stopped, and the gripping of the vibro-pile driver 17 is released. Only the internally inserted pipe 10 is gripped by the gripping means of the vibro-pile driver 17, and the internally inserted pipe 10 is pulled up together with the vibro-pile driver 17. The process is repeated, and underwater steel-pipe-sheet piles are driven.

摘要： PURPOSE:To construct a continuous underground wall efficiently by repeating the work building H-shaped steel piles in a groove formed by the combination of a reverse circulation drill and a clamshell bucket in the construction of the continuous under-ground wall of large size and great depth. CONSTITUTION:First, pits are made at given intervals by using an excavator such as a reverse circulation drill and then the natural earth left between the pits is excavated by using an excavator such as a clamshell bucket, thereby a groove with a fixed length being formed. In the groove thus formed one or plural number of H- shaped steel piles 4 are inserted, the flange parts thereof being connected, and in the boxes formed between the piles and in the spaces between the line of steel piles and the natural earth the concrete is struck, thus a wall elements 9 being constructed. Next, the prior hole 8 is dug further, and in the long groove formed by excavating the part between the above hole and the existing wall element 9 by the clamshell bucket, etc. another wall element is constructed in the same way. By repeating the above operations, a continuous underground wall is constructed.
