Bridge water surface pile tie beam hoisting device and construction method thereof

Abstract

The invention discloses a bridge water surface pile tie beam hoisting device and a construction method thereof.The bridge water surface pile tie beam hoisting device comprises a hoisting point support, a bearing mechanism and a pile tie beam wood formwork, a hoisting component is arranged between the hoisting point support and the bearing mechanism, and the bearing mechanism comprises a plurality of lower longitudinal beams and bearing beams arranged on the lower longitudinal beams; the pile tie beam wood formwork comprises square timbers and bamboo plywood. The hoisting component comprises a hoisting rod, an upper adjusting nut arranged on the hoisting rod in a sleeving mode and a lower locking nut arranged on the hoisting rod in a sleeving mode. The method comprises the following steps: 1, preparing before construction; 2, mounting a hoisting device; 3, hoisting the bearing beam for the first time; 4, mounting a timber formwork of the pile tie beam; 5, binding a pier pile foundation reinforcement cage and a pile tie beam reinforcement cage; 6, conducting secondary hoisting of the bearing beam and the pile tie beam wood formwork; and 7, installing a pier pile foundation steel formwork and a pile tie beam side steel formwork, and pouring concrete. The construction method is reasonable in design, hoisting of the pile tie beam construction formwork is achieved, and then concrete pouring construction of the pile tie beam is completed.

Description

technical field [0001] The invention belongs to the technical field of bridge water surface pile tie beams, in particular to a hoisting device for bridge water surface pile tie beams and a construction method thereof. Background technique [0002] Pile tie beam is a horizontal connection beam structure located at the top of the pile foundation (bottom of the pier column), which mainly increases the overall stiffness of the pile foundation, so that the two pile foundations are connected into a whole, and jointly bear the upper load. In the construction of bridges in water, pile foundations, tie beams, and caps in water are the most difficult points in the construction process. The existing technology uses cofferdams, steel casings and other construction methods based on the difference in elevation and position of pile tie beams. The construction technology of the water surface tie beam is even more affected by the land construction technology. The construction environment is ...
