Description
Technical Field
The utility model relates to a pond technical field, concretely relates to assembled pond post-tensioning method annular prestressed structure.
Background
Domestic concrete ponds are mostly cast in situ, and the prestress technology effectively controls cracks of concrete generated due to the comprehensive effect of temperature and humidity difference and passes practical tests in the cast-in-situ ponds. The prefabricated components of the assembled circular water pool are spliced together, and the stability of the structure is enhanced by adopting a prestress wire winding method outside the wall body, so that the anti-seepage requirement is met; the prefabricated parts of the assembly type rectangular pool are connected in a wet mode through a post-pouring belt method, and the firmness of the whole structure is guaranteed.
Post-tensioning, with adhesive pre-stressing. The concrete is poured firstly, and the steel bar (reinforcing bar bundle) is stretched after the concrete reaches over 75 percent of the designed strength. The main tensioning procedure is embedding pipe and making hole → pouring concrete → pumping pipe → maintaining and stretching through reinforcing bar → anchoring → grouting (preventing reinforcing bar from rusting). The force transmission path is that the anchorage device is used for preventing the elastic rebound of the steel bar, so that the section concrete obtains the pre-compression stress; post-tensioning, no pre-stressing of the bond. The main tensioning procedure is that prestressed reinforcement is coated with lubricating and anticorrosive materials such as asphalt along the whole length of the outer surface → plastic paper or a sleeve is coated (the prestressed reinforcement and concrete do not build adhesive force) → concrete pouring maintenance → tensioned reinforcement → anchoring.
The prestress of the assembled rectangular water pool is mainly straight stretching, the times are more, time and labor are wasted, materials are wasted, and the construction cost is not saved.
