Prepressing method for hanging basket jack
The invention discloses a prepressing method for a hanging basket jack. To make the stress state of the pressure test loading process coincide with that of the practical construction work, the jack is adopted for conducting loading and prepressing to a hanging basket at the midspan of a beam bottom plate of a section 1#, namely a reaction frame is arranged on the end face of a web of a section 0#, by utilizing the opposite acting force of the reaction frame, the opposite acting force is transformed to the bottom plate of the hanging basket through the jack, a sleeper distributive girder or a square timber distributive girder and a wooden plate cushion for exerting the required prepressing load, the concrete load level of the heaviest section is simulated for conducting loading, the technical effects are achieved, namely the prepressing method for the hanging basket jack is convenient and timesaving, the consumption of material resources is little, it can be guaranteed that a pile cap foundation pit is backfilled timely, the construction of a block support foundation 0# is guaranteed, the bottom plate of the hanging basket is stressed more uniformly, the prepressing load of the hanging basket is closer to the practical construction conditions, the processing of the reaction frame and embedded components is simpler, and the operation is easier.
