Ultrahigh aqueduct local dismantling and rebuilding system and construction method

Abstract

The invention provides an ultrahigh aqueduct local dismantling and rebuilding system and a construction method. An outer formwork supporting plate can move along a supporting plate sliding groove under the action of a lateral position adjusting body; an inner mold connecting plate is arranged in the middle of the aqueduct inner mold, and lateral position control pressure can be provided for the aqueduct inner mold through a wedge-shaped pressing plate; aqueduct top mold position control is conducted through the top mold position control body; the aqueduct to be cleared is hoisted and removed through a supporting hanging bracket; an aqueduct positioning device is adopted to control the position of the section aqueduct; connecting tenon ribs and post-cast connecting tenons are additionally arranged at the connecting parts of the connecting cross beams and the segment aqueducts; overhanging drainage pipes and permeable filling bodies are laid in the rear drainage grooves, and connecting anchor bars, joint grouting bodies and joint waterproof strips are arranged at the joints of the segment aqueducts and the reserved aqueducts; a joint sealing body, a tongue-and-groove tenon, a tongue-and-groove groove and a connecting anchor bar are arranged at the joint of the segment aqueduct, and fastening tension can be applied to the segment aqueduct through a pre-stressed anchor bolt. The construction efficiency can be improved, the aqueduct rebuilding construction quality is improved, and the traffic influence is reduced.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a partial demolition and reconstruction system and construction method of an ultra-high aqueduct. Background technique [0002] As an important water passing structure above the road, aqueducts have been widely used in water conveyance projects. During the use of aqueducts, it is often necessary to dismantle and rebuild damaged aqueducts. During the demolition and reconstruction of the aqueduct, how to improve the efficiency and quality of the aqueduct replacement construction, improve the performance of the aqueduct, and improve the connection strength of the old and new joints have always been the focus and difficulty of engineering control. [0003] There is a construction method for the aqueduct body in the prior art, including material preparation and preparation of construction tools; preliminary cover beam construction; foundation treatment; making auxiliary supports;...

AI Technical Summary

Problems solved by technology

Although this technology can meet the requirements of cast-in-situ construction of the aqueduct body, it is difficult to improve the efficiency of aqueduct repair construction and improve the connection performance of the old and new aqueducts
