Combined with the hanging basket pouring construction process, the paper puts forward the quality control points and methods of hanging basket continuous casting box girder
The hanging basket in the process of walking, the two should be a walking anchor beam as a whole, to prevent the process of walking anchor beam deviation affect the normal walking, if found walking anchor beam walking by right, should immediately stop walking, the first of its position is adjusted during walking, should additional insurance is hard on walking anchor, anchor in order to adjust the position of the beam;After hanging blue in place, should immediately after the anchor, the box and the top of the box sling anchor, it is strictly prohibited to use internal and external guide beam frame for box beam concrete construction.
Hanging basket when walking, hanging basket as far as possible to do the same time, the difference between the asymmetric distance between the hanging basket is 5cm;One must be responsible for observing the synchronization of walking, the two person is responsible for observing the operation of the walking anchor beam, the two is responsible for observing the operation of the outer die frame bearing;
The key points of quality control: 1, hanging basket template (including the bottom mold and the side mold) elevation 2, hanging basket preloading ensuring the load quantity; 3, the hanging basket forward, need special attention, when the cradle walking the preparatory work before the improvement, check again walking and walking condition of anchor beam connection rod the bottom, hanging point should adopt steel wedge pad, and ensure the stability of suspension;
