Q:Construction of hanging basket

After the completion of the completion of each block of concrete to meet the requirements of the standard strength, timely butt joint surface of the hair, the quality of the hair in strict accordance with the requirements of the specification control. In the next section of concrete pouring, the surface of the right amount of water to wet, to prevent the concrete joint out of dry shrinkage cracks.

Q: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.

Q:How to deal with the broken of the cross beam of the hanging basket

Your cantilever cast-in-place box girder is not prestressed construction.Need to identify the type of crack, if it is hot up cracks or superficial expansion cracks, the depth of not more than 2mm, not to the vertical and horizontal direction of development is not related, you can not deal with.

Q:Is hanging basket equipment special equipment? Need to record it?

After the completion of the installation of special equipment, construction safety supervision station shall apply for registration procedures

Q:Are there any hanging baskets on both sides of the hanging beam 0

In the 1# pre pressure when the basket has been removed from the non elastic deformation, so no need to hang basket that is 2# block pre pressure.

Q:I would like to know that each piece of the construction of the hanging basket is connected by way of the whole as a whole, I always think of each section is a section of tension.As you said, the steel strand is the length of the whole beam, but how to form the whole concrete?

Each section of the pouring, the prestressed pipe to stay in that, when the tension, only pull the section of prestressed reinforcement. Those who like long, without tension will not wear.
