Prestressed pipe pressure slurry before concrete pouring construction requirements

The provisions of article 1 of the, is still dealing with embedded in the concrete anchorage, pipe and steel, etc. To conduct a comprehensive inspection acceptance, rear can start casting conforms to the requirements. Prestressed concrete pipe pressure slurry casting, should be selected according to different forms of structure or component plug-in, attached type or plate type vibrating vibrator. Retainer of junction box girder web plate and bottom plate and roof, fixed area of prestressed reinforcement and other body parts with dense prestressed steel beam and steel bar, effective measures should be taken to strengthen vibrating; For a first component should avoid vibrator collision prestressed reinforcement; Should avoid vibrator collision structure of post-tensioned prestressed concrete pipe, embedded parts, etc. Prestressed pipe pressure slurry in the process of the construction before pouring should check the template, the stability of the pipe, anchor end plate, etc, ensure the position and size comply with the design requirements. Prestressed pipe pressure slurry used to determine the concrete specimen, the strength of prestressed concrete structure or member should be placed in the scene with the structure or component and the environment, and condition maintenance.
