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： PROBLEM TO BE SOLVED: To contrive to enhance a positioning work of reinforcing bars by corresponding the number of reels with the number of flexible reinforcing bars to be positioned and communicating and interposing a friction resistance reduction member and a clutch means between a drum and the reels. SOLUTION: In the case when flexible reinforcing bars 14 are withdrawn one by one from a take-up reel 13, a clutch cylinder 16 set up to correspond with the take-up reel 13, which is to be turned, is extended, thereby shortening the other clutch cylinder 16. At that time, a reel stopper 23 responding thereto is extended to the take-up reel 13, which is not allowed to turn, thereby preventing the take-up reel from turning. Since each reel is turnable properly and individually, it is, therefore, possible to adjust the positioning length of flexible reinforcing bars substantially equally.

摘要： PURPOSE: To securely install a continuous underground wall, by fixing a water feed device which is extensible by a spring to a vertical member erected in the continuous underground wall made of soil segment and pushing the device by the spring force to form a water passage before the coil cement is cured. CONSTITUTION: A water feed device 20 in which filter materials 24 are fixed to both ends of a double-tube 21, 22 extending or contracting by the force of a coil spring 23, is fixed in a hole 12 bored on the flange 11 of a vertical member made of a H-shaped steel material or the like through a stopper plate 30. The devices 20 are fitted in multiple stages according to the position and quantity of underground water. The vertical members 10a are driven at every specified distance before cure of the continuous underground footing (soil cement wall) which is constructed by agitating and mixing a curing agent with soil at site and the stopper plate 30 is drawn and the water feed device 20 is pushed in the soil cement by the spring 23 force to form a passage for underground water. In this way, underground water cut off by the continuous underground wall can be easily conducted.

摘要： PROBLEM TO BE SOLVED: To provide a device and method for continuously arranging a reinforcing bar, in a construction step of an underground continuous wall, in which a flexible reinforcing bar is used. SOLUTION: A reinforcing bar curing base 29 comprising a beam material is provided at the top end of a continuous wall construction groove and a reinforcing bar arranging device comprising a frame body 10, a reinforcing bar feed means, and a reinforcing bar guiding means is provided on the upper part of the groove. Reinforcing bars are delivered by the reinforcing bar feed means and after a required number of reinforcing bars are formed into a predetermined bundled state by means of the reinforcing bar guiding means, the bars are bundled together at a predetermined pitch to form main reinforcing bars S. And the bars S are pulled out to the base 29 and a lower frame F1 is inserted into the interior of the bars S so as to be suspended therein. Next, while a horizontal reinforcing bar panel Y is being attached to the bars S, the frame F1 is lowered to the groove and an intermediate frame and a top frame are attached at a predetermined interval. Top parts of the main reinforcing bars are fixed to the base 29 using a wedge member and the main bars S are cut off at a level above the fixed point. And concrete is placed up to the lower part of the base 29 to construct a continuous wall and then the base 29 is removed.

摘要： PROBLEM TO BE SOLVED: To dispense with a high working space at the upper part of an exavation hole, by attaching lateral reinforcements taken out of a containing device of the lateral reinforcements to the periphery of vertical reinforcements in turn while inserting a plurality of vertical reinforcements at a specified position in an excavated hole. SOLUTION: A containing device 2 of lateral reinforcements is installed at the inner peripheral face of the opening end of an excavated hole 1. A guide frame 5 is arranged above a curing base 4 by supporting it by legs 51. Required number of vertical flexible reinforcements 6 drawn from a drum are inserted in the guide pipes 52 corresponding thereto respectively and inserted into the excavated hole 1 after a shape-retaining frame has been fitted. Lateral reinforcements 3 taken out of the containing device 2 are fitted to the periphery of the vertical flexible reinforcements 6 by welding or the like in parallel to the above insertion work. The lateral reinforcements 3 are urged so as to be extruded upward and hence, they can be taken out of the containing space 23 of the lateral reinforcements with a little force.
