Description
Technical field
The present invention relates to method for bridge construction, specially construction of the end bay without wet seam precast segment free cantilever erection continuous beam
Method.
Background technique
Precast segment assembling technique is longitudinally split by beam body into several segments, in factory or at the construction field (site) according to predetermined
Design scheme carry out it is prefabricated, by segmental erection it is in place after, stretch-draw prestressing force steel beam, which gets up each section assembling, becomes complete
Beam body.Nowadays the connecting method between beam sections mostly use adhesive for concrete be bonded bonding mode or for segment between in advance
The wet of armored concrete is stayed to connect mode.Bonding mode is chiefly used between precast segment block, and the wet mode that connects then is chiefly used in precast segment
Between block and non-precast segment block, that is, fragment position of joining the two sections of a bridge, etc.
In prefabrication and assembly construction bridge common at present, end bay closure section and midspan closing section are still applied using cast-in-place mode
Work, there are still certain rising spaces for this kind of bridge prefabrication rate, and when the construction of wet seam, are limited by field condition, closure section construction
Quality is difficult to control；Set up the duration of the processes such as template, assembling reinforcement, casting concrete, concrete curing, form removal in scene
It is longer.In addition, the wet seam precision of closure section is not high and speed is slower, construction efficiency is still to be improved.
Summary of the invention
The purpose of the present invention is to solve the technical problem in above-mentioned background technique, propose a kind of end bay without wet seam section
