Description
Technical field
The present invention relates to a kind of assembled pier that can be applicable to seismic fortification intensity upper zone and construction technology thereof, belong to
The technical field of construction of road and bridge.
Background technology
In bridge construction process, being particularly in the bridge of city or ecological preservation area, the subject matter faced is concentrated
In following two aspect, one is to speed up the construction period, reduces the impact on existing traffic;Two is to reduce construction to surrounding enviroment
Impact impact, keeps the ecological looks of surrounding enviroment not to be damaged.For these reasons, traditional cast-in-place concrete bridge construction
Technology can not fully meet the bridge construction construction requirements of modernization.
From construction angle, bridge pier is divided into assembled pier stud and integral cast-in-situ pier stud.Integral cast-in-situ pier stud has excellent
Overall performance, use the most in a large number.The nearly more than ten years just start the use of substructure assembled pier stud, in recent years complete bigger under
Portion's precast construction is such as: Hangzhou Gulf Great Bridge, Changjiang River Bridge Shanghai etc., but, existing assembled pier stud rests on single connecing mostly
In the type of attachment of seam, and wet seam uses in the majority, can't connect sections and propose a kind of effective control method.Therefore
The dual connection design of the present invention is just particularly important.
But, domestic and international existing technical standard, specification and Experimental Establishment the most do not connect the connection of seam crossing to sections
Propose a kind of effective method of attachment, only the mechanical behavior of single seam is carried out certain research.A lot of domestic exterior
That joins sections in formula pier stud is effectively connected to become one of assembled pier stud key factor whether standing seismic stimulation effect, but
Do not provide one and facilitate feasible method.
Therefore, those skilled in the art is devoted to develop a kind of assembling that can be applicable to seismic fortification intensity upper zone
Formula pier, is not that single seam carries out mechanical behavior analysis, but the behavior that abutment joint connects carries out two ore control, so that knot
The anti-seismic performance of structure obtains satisfied effect.
Summary of the invention
The problem that the present invention is directed to the existence of above-mentioned prior art makes improvement, i.e. the technical problem to be solved is
A kind of easy construction is provided, shortens the construction period and connect the assembled that can be applicable to seismic fortification intensity upper zone reliably
Pier and construction technology thereof.
In order to solve above-mentioned technical problem, the technical scheme is that
Present invention can apply to the assembled pier of seismic fortification intensity upper zone, it is characterised in that: include a set of dual connection
