Balloon - hollow inside prefabricated rubber mold professional

 Balloon - hollow inside prefabricated rubber mold professional, vista. 1, bridge rubber balloon into the mold A prefabricated bridges prefabricated rubber balloon surface evenly release agent. B with a rope pulling the bridge rubber balloon penetrates end of a prefabricated concrete steel cage, and prefabricated bridge rubber inflatable balloon placed outside the mouth. Prefabricated bridge rubber inflatable balloon using method 2 A prefabricated bridge rubber balloon to open the inlet valve inflated. Inflatable air pressure with a pressure gauge control monitoring. B when the air pressure to use air pressure, the intake valve closes. C shaped prefabricated bridge rubber balloon should be inflated until the use of alternating pressure. D Note that no excessive pressure when used. 3 A fixed and pouring concrete at the pound vibration rubber precast concrete bridge balloon will go up, therefore, must be fixed up and down, generally 250MM diameter mandrel stirrup spacing 80cm, such as diameter increased, the spacing corresponding narrowing. 96 B method is the heart and pouring concrete to build basically the same, note the use of high-frequency vibration rod inserted or pound pound vibration simultaneously from both sides, to prevent prefabricated bridge rubber balloon about displacement. Pound vibrating rod ends is best not to touch the core module. 4 form removal when the initial setting of concrete, open the bleed valve, you can be prefabricated bridge rubber balloon extraction, removal time visualization number of cement. kbx 5 Rinse prefabricated bridge rubber balloon, to test the water test. Please take off in order to keep prefabricated bridge rubber balloon reusable rubber mandrel use a rubber mandrel into the mold A rubber core mold surface evenly release agent. B with a rope pulling the rubber end of a mandrel penetration of concrete reinforcement cage, and inflatable rubber mandrel placed outside the mouth. A two inflatable open the inlet valve of the inflatable rubber mandrel. Inflatable air pressure with a pressure gauge control monitoring. B when the air pressure to use air pressure, the intake valve closes. C-shaped rubber mandrel should be alternately inflated until use air pressure. D Note that no excessive pressure when used.
