摘要： PROBLEM TO BE SOLVED: To provide continuous underground wall technique for eliminating a mud film adhering to the wall of a excavated ditch and making underground water pass satisfactorily. SOLUTION: A permeable mat 3 is disposed in a position of covering an opening part of a water flow pipe 2, and muddy water in the permeable mat 3 is substituted with a mud film decomposing enzyme solution through a pipe body so as to weaken the connection of a mud film. Air is made flow into the permeable mat 3 and exhausted through a pipe body. The decomposing enzyme solution in the permeable mat 3 is thereby oscillated to further weaken the mud film. Water level in the permeable mat 3 is made lower than underground water level to make underground water flow into the permeable mat 3. The mud film adhering to the permeable mat 3 is thereby separated, and water containing mud film components is drained through the pipe body so as to ensure excellent permeability of the permeable mat 3 and to accelerate the water flowability of the water flow pipe 2.

摘要： PROBLEM TO BE SOLVED: To make it possible to change the thickness of an underground wall to comply with stress and thereby execute work by inserting a cage which reduces its upper wall thickness into an excavated ditch and inserting a wedge- like pull-out form into the ditch in such a state that its maximum width side may be positioned on the upper part and then placing concrete. SOLUTION: A general excavating machine is used to excavate a ditch whose thickness is uniform from the upper end to the bottom where the ditch is excavated while a stabilizing liquid is being filled up. Then, a cage 2, whose upper part is thinly shaped up, is lowered and inserted into the ditch. Then, a wedge- like pull-out type form 3 is inserted into the ditch and then concrete is placed into the ditch. When the concrete is cured and unaided support is available, the wedge-like pull-out form 3 is pulled up to the ground. Then, a slope-shaped space is produced in that area. To comply with this, a backfill material is filled up so as to prevent the collapse of the ditch if the space is located on a natural ground side. This construction makes it possible to change the thickness of an underground wall, responding to stress and thereby execute work.

摘要： PURPOSE:To provide an underground wall which can be used as an impervious wall during construction work and which can be made permeable after completion of construction work by disposing a biodegradable material in a permeable hole passing through the underground wall. CONSTITUTION:An excavated groove 3 is excavated in the ground and a cage of reinforcing bar 12 is disposed in the groove 3. A permeable pipe 21 is disposed at several points of the cage 12 so that the opposite ends of the pipe 21 are positioned adjacent to a permeable layer 31. Next, the opposite ends of the pipe 21 are closed with a cover 23 made of biodegradable material and the outer surface of the cover 23 is coated with a thin film 24 and also water sealing material 26 is filled into the peripheral surface of the cover 23. And concrete is cast into the groove 3 and cured to construct an underground wall. And muddy water mixed with bacteria is supplied from a supply pipe 25. As a result, after completion of the construction work, when the cover 23 is biodegraded and ceases to exist, the pipe 21 becomes permeable so that flow of underground water is restored.

摘要： PURPOSE:To enable underground water to be permeable. CONSTITUTION:A sheet 11 is laid out to both wall surfaces of an excavation ditch 20 where an inlet pipe 12 is mounted to the sheet 11. The inlet pipe 12 is connected to a transparent water hose 13 which may be bent or expansible. When concrete is filled up between the sheets 11, the transparent water hose 13 may extend so that the sheet 11 may come in contact with the wall surface of the excavation ditch 20. As a result, underground water may flow from one wall surface of the continuous wall to the other surface by way of the inlet pipe 12 and the transparent water hose 13.
