摘要： PURPOSE:To improve the strength and shielding performance of a continuous underground wall having a changed section part changing in a sectional form by buriedly providing a belt-shaped reinforcing member having shielding function along the changed section part. CONSTITUTION:A reinforcing member 5 is formed of material having proper strength and shielding ability, for instance a steel plate or synthetic resin, and previously attached to a reinforcement cage arranged inside a continuous underground wall 1. Next the reinforcement cage is arranged to construct the continuous underground wall 1 having a changed section part 4. In this case, the reinforcing member 5 is buriedly provided along the changed section part 4 so as to spread over both walls 2, 3. Thus, since the changed section part 4 is buriedly provided with the reinforcing member 5, even if stress concentrates at the changed section part 4, a crack does not occur in the changed section part 4, and if the crack occurs, the reinforcing member 5 can prevent water leakage into the inside of the continuous underground wall 1.

摘要： PURPOSE:To accomplish a digging work safely and to apply large supporting force to a caisson type pile by dividing an enlarged base into plural virtual blocks, and repeating digging and earth retaining work for every block. CONSTITUTION:A pile hole 1 with a uniform diameter corresponding to the shaft part of a caisson type pile is dug. while earth retaining is performed. The enlarged base is virtually divided into the respective layers A1-A3. Further, each layer is virtually divided into plural blocks along the circumference. In every block, lock bolts 3 are radially driven in from the inside of the pile hole. Subsequently, according to the inclination of the enlarged base, the sediment outside the pile hole is scraped and the divided inclined surface 12 connected to the pile hole is dug. A consolidation material 4a is sprayed on the divided inclined surface 12, and the lock bolts are screwed by nuts to prevent fall of earth of the divided inclined surface 12. Subsequently, digging and earth retaining work are repeated for every virtual block. Thus, the natural ground can be supported by large supporting force, so that a digging work can be performed safely.

摘要： PURPOSE:To shorten the period of construction and enhance the accuracy of operations by removing slime from the end portion of an excavated trench when a trench is excavated for following wall and the end of a preceding wall is excavated. CONSTITUTION:In the construction of underground continuous wall, trenches 1 for preceding wall 4 are excavated at a fixed interval, and concrete 3 is impregnated into the trenches 1. Before the curing of concrete, partition parts A are driven into slightly inside of the end in the jointing direction and also into at least the upper end side. The partition parts A are then removed to form spaces in slightly inside of the end of the jointing direction. The area between the spaces is excavated and concrete is impregnated to form a following wall connected to the preceding wall in order to construct a continuous wall under the ground.

摘要： PURPOSE:To obtain both water-stop function and base pile function by a method in which spherical footings having a larger-diameter support function than the diameter of a pile are integrally formed partly on the lower part of a sheathing wall made up of adjacent column lines. CONSTITUTION:The first column-line wall 2a is constructed to a given depth by a soil mixture obtained by mixing a solidifying agent from a multi-shaft auger 1 and soil on site. A large-diameter spherical footing 3a is extendedly constructed on the lower end of the wall 2a, and a stress material 4 of a sufficient length to reach the footing 3a is set in the wall 2a from the ground's surface to make up a column-line sheathing wall. The first column-line wall 2b having a spherical footing 3b is constructed at a fixed distance from the wall 2a, and the second column-line wall 2c is constructed by using an auger 1 between the walls 2a and 2b to obtain a continuous column-line wall 2. The column-line sheathing wall having a water-stop function and a great tip supporting force can thus be obtained.

摘要： PURPOSE:To heighten the joining strength of guide blocks connected together by joining a guide block with another adjoining guide block by means of mounting a bolt through a bolt hole as a bolt mounting device is moved in alignment with a guide member. CONSTITUTION:A reaction plate 4 on both sides of a joining surface 11 of an existing guide block 1a is fixed by holding it between fixed jacks 55, 56 of a position adjusting device 5. The reaction plate 4 of a newly installed guide block 1b is pressed toward the existing guide block 1a with a drag-in jack 57 to bring the joining surface 11 of both guide blocks close together. Simultaneously, installation of the newly installed guide block 1b is performed as the position in the continued direction of the continuous underground wall and the right angle direction is adjusted with a right angle direction adjusting jack 58. As a bolt mounting device 6 is ascented and descented in alignment with a guide member 2, a bolt B is inserted into a bolt hole 14, turned and screwed into a built-in nut 3. Both blocks 1a, 1b is joined into one unit by screwing the bolt B into all bolt holes 14.

摘要： PURPOSE:To increase connection strength by fitting a hollow succeeding guide block between hollow preceding guide blocks arranged to a continuous underground wall and integrally joining the preceding guide blocks and the succeeding guide block. CONSTITUTION:The upper end section of a downward spreading-shaped hollow guide block 1, upper and lower ends of which are opened, is exposed from the top face of water, a lower end section is buried up to specified depth in a water bottom ground 5, and a plurality of the guide blocks 1 are disposed in the continuous direction of a continuous underground wall at regular intervals. Upward spreading-shaped hollow succeeding guide blocks 2, upper and lower ends of which are opened, are installed among the preceding guide blocks 1 in such a manner that both irregular sections are fitted, upper end sections are exposed from the top face of water and lower end sections are buried up to specified depth in the water bottom ground 5. The insides of holes for cut-off formed by joining grooves for cut-off notched near both end sections of both inclined faces are filled with cut-off materials, thus completing the installation execution of the guide blocks.

摘要： PURPOSE:To adjust apparent weight of a bank when banking is executed by after banking weight adjusting bodies downward in multiple stages on a base ground through a hose for fluid absorption/discharge, operating a fluid absorption/discharge device. CONSTITUTION:When banking is executed on a base ground 3, hollow weight adjusting bodies 1 that can adjust inner pressure are placed downward and set, and after a hose 2 is set thereto, a bank 4 is constructed and each weight adjusting body 1 is buried. After the hose 2 to which the weight adjusting body 1 of a number of stages that are equal to the height of the banking body and the set things are buried by the bank 4, a roof 6 is laid topmost. By the operation of a fluid absorption/discharge device 5 linked to a base end of the hose 2, air and so on can be attracted or compressed to the weight adjusting body 1. By the simple construction, apparent weight of a banking body can be adjusted, and even for a soft base ground, the effect thereby can be restricted to a lowest limit.

摘要： PURPOSE:To make collecting of groundwater in a wide-ranged area economically possible by constructing a plurality of shafts, penetrating through the permeable layer, and a horizontal conduit for connecting each of the shafts, and by providing pumping equipment to smaller numbers of the shafts. CONSTITUTION:A continuous underground wall 1 is constructed at a place where running gradient of groundwater is appropriate. Then a collecting-and- pumping shaft 2 and collecting shafts 3, each having wall surfaces made of porous material, are constructed upright at upstream side of the continuous underground wall 1, and pumping equipment comprising pumps and pumping pipes is provided at the bottom of the collecting-and-pumping shaft 2. Lower part of all of the shafts 2 and 3 are then connected with the pumping equipment installed only to smaller numbers of the collecting-and-pumping shafts 2 and, at the same time, number of collecting shafts 3 can be smaller than in a structure of conventional type.
