Question:

Hanging basket concrete pouring construction control points

nan

Answer:

Management points:1 the concrete pouring on both sides of the beam should be symmetrical and balanced, and the unbalanced construction load should not be greater than the allowable value;2 concrete should be rapid, continuous construction, in the first pouring of concrete before the first pouring all completed;3 the bottom plate, the web and the roof are symmetrically layered, and the layer thickness should not be greater than 30cm;4 continuously change the height of the hanging basket in the process of concrete pouring;5 the quality of the installation of the prestressed channel, unobstructed inspection and plugging treatment;6 the vibration of concrete should meet the requirements of construction technology, it is appropriate to use high-frequency attachment vibrator with vibration;7 the temperature and air content of concrete in mold meet the design requirements;8 test specimens of concrete strength and elastic modulus.
3 pouring operations caused by the deformation of the prestressed channel deformation, deflection, etc.;4 concrete upper and lower intervals for too long, resulting in construction joints;
Construction control points of concrete pouring basket:1 tamping is not dense, not dense, missing tamping concrete honeycomb;2 both ends of the section pouring speed is not the same, resulting in unbalanced force;
