摘要： PURPOSE:To completely and simply close observatory wells, etc., by packing hydro-concrete into the underground pipe of the observatory well. CONSTITUTION:A container 3 is set to the upper end of an underground pipe 1 through a valve 2, and a hydro-concrete 4 or a mixture of hydro-concrete 4 and waters 5 and 6 is packed into the container 3. The inside of the container 3 is practically isolated from the atmospheric air, the valve 2 is opened, and the hydro-concrete 4 is dropped into the pipe 1 and hardened. The underground pipe 1 can thus be completely closed with the concrete without forming any water channel, and thereby the inflow of groundwater into the pipe 1 can be prevented.

摘要： PURPOSE:To efficiently erect underground continuous wall by a method that, after preventing adherence of slime by covering horizontal reinforcements of reinforced cages for a preceding panel with protective plates, the reinforcements are set so as to lap with horizontal reinforcements of reinforced cages for a succeeding panel, and concrete is placed. CONSTITUTION:After reinforced cages 10A for the preceding panel 10 are set in a preceding excavated ditch 35, the preceding panel 10 is made by placing concrete. Then, projected horizontal reinforcements 13A of the cages 10A are covered by setting the protective plates 22 to the end of the panel 10. After a succeeding ditch 40 is excavated, the end of the panel 10 is cleaned in pulling up the protective plates 22. The reinforced cages 11A for the succeeding panel are set in the succeeding excavated ditches 40 so that the horizontal reinforcements 13B lap with the reinforcements 13A of the cages 10A of the panel 10. Then, the succeeding panel 11 is built by placing concrete.

摘要： PURPOSE:To prevent the adherence of clay cakes to a partition plate by a method in which a temporary bonding plate is closely contacted with the following panel side of the partition plate for a reinforcing bar basket, and before placing concrete for the following panels, the temporary bonding plate is removed out. CONSTITUTION:A temporary bonding plate 6, e.g, thin steel sheet, etc., is beforehand closely attached to the face on the following panel side (b) of a partition plate 1 for a reinforcing bar basket. In constructing preceding panels, the reinforcing bar basket is inserted into an excavated hole, and concrete 9 is placed. In this case, bentonite mud water is usually put in the preceding excavated hole 10, and the cake of clay particles is adhered to the surface of the temporary bonding plate 6 mainly. After a trench for following panels is completed, a reinforcing bar basket for following panels is inserted into the trench, the temporary bonding plate 6 is removed from the plate 1 and pulled up to the ground's surface, and concrete is palced. The adherence of the cake of clay particles to the partition plate 1 can thus be prevented.

摘要： PURPOSE:To improve the bonding between a steel part and concrete by a method in which current is flowed between an anode inserted into a stabilizer liquid and a custom-made steel part as a cathode immediately before the placement of concrete and clay particles adhered to the steel part are removed. CONSTITUTION:An iron bar cage 5 is set in an excavated trench 1, and then an electrode 7 is inserted into the cage 5 immediately before the placement of concrete. The electrode 7 is connected to the plus side of an external DC power source device 8 and a partition iron plate 3 and cross bars 4 are connected to the minus side of the power source device 8. Current of 5A/m or more is then flowed between both the electrodes so that clay particles adhered to the iron plate 3 and the cross bars 4 are separated due to the formation of the film of water as a diaphragm between iron bars 3 and the cross bars 4. Afterwards, concrete is placed and hardened.

摘要： PROBLEM TO BE SOLVED: To construct an underground tank of economical and favorable quality. SOLUTION: A side wall 1 is sunk to the inside of the ground 5 in an open caisson construction method, and an inner part of the side wall 1 is dug in water. A float 17 is provided to float on a water surface 13. A bottom plate casing body 23 having a cavity 25 is provided on an upper surface of the float 17, a cement paste or the like is injected into the float 17, and it is sunk. After cut-off construction 27 is applied to a boundary part between the side wall and the bottom plate casing body 23, water 11 inside the side wall 1 is drained, and hardening material is injected into the cavity 25 to be filled. Connection concrete 29 to connect the side wall 1 to the bottom plate casing body 23 is then constructed, and a roof 31 is placed on the side wall 1 to complete an underground tank 33.

摘要： PURPOSE:To prevent leak of concrete placed between partitions, by a method wherein a sheet is stretched to the bottom or the sides between a pair of the partitions, a reinforcing bar cage is contained between the partitions, and the end of the reinforcing bar cage is emerged from the partition to build a preceding panel. CONSTITUTION:A reinforcing bar cage 3 is placed between a pair of partitions 2, and the end of the reinforcing bar cage 3 is emerged from the partitions 2. A form material is secured between the lower ends of the partitions 2. A bottom sheet 11 is stretched on the form material, side sheets 13 are stretched between the opposing ends of the partitions 2 to form a preceding panel A which is inserted in a ditch in a continuous underground wall. This enables prevention of leak of concrete poured between the partitions 2 or enables concrete to be prevented from flowing round and entering the juncture between the preceding and a subsequent panel.
