Description
Technical field
The invention belongs to bridge maintenance field of reinforcement, and in particular to a kind of bridge pier small axial dimension of beam body transverse direction deviation is entangled
Deflection device and method for correcting error.
Background technology
Bridge can be divided into five kinds of beam bridge, rigid frame bridge, arch bridge, cable-stayed bridge and suspension bridge primary structures by structure type.Its
Middle beam bridge because it is at low cost, the completion time of project is short, good integrity, reasonable stress, span ability are big, in Urban Bridge and highway bridge
In be able to extensive use.
For beam bridge, important component of the beam body as bridge structure is the main supporting member in bridge top, is vehicle
Safety, cosily traveling provides channel.Beam body is during construction, operation, since external environment, natural calamity, automobile move
Power load, bearing installation injustice, the factors such as beam bottom horizontal wall inscription, may cause beam body transverse direction deviation, this bridge defect it is gradual
Accumulation, can cause the safety of bridge structure certain consequence.It is small, the comfort of driving is influenced, then gives people's lives and properties greatly
Bring significant damage.Therefore, it is necessary to be adopted vigorous measures in time to cope with the beam body deviation disease being likely to occur, made with restoring it
Use function.
Traditional replacing and rectificating method is typically first to be jacked beam body with jack, then fall reset.Above-mentioned traditional entangles
Inclined repositioning method has following three：（1）It needs to set up falsework in bridge pier side, it is time-consuming；（2）Falsework
Additional bracket basis is generally required, and when bridge pier is higher, stent needs to ensure because bearing the reaction force of pushing tow beam body
Securely, reliably；（3）Belong to two independent structures between falsework and bridge pier, thrusting action power will pass to lower bridge
Pier may cause bridge pier to crack, and be unfavorable for bridge pier stress, bring new disease.
In addition, the Chinese patent literature that document number is CN205188840U discloses a kind of bridge lateral pushing tow correction dress
It puts, using lateral pushing jack, when beam body transverse direction deviation is larger, lateral deviation is more than laterally as lateral pushing equipment
The rated travel of jack in actual mechanical process, needs steel cushion block of constantly jumping a queue between beam body and lateral jack, operation
It is improper to be also possible to that beam body elastic reset is caused（It is returned to original position before beam body is rectified a deviation）.In addition, this deviation correcting device needs
Steel hoop is installed on pier stud, therefore, the method for this lateral pushing correction has certain limitation, it is impossible to be used in has nature
Lateral deviation caused by the factors such as disaster is larger, situation beyond its stroke, it is therefore desirable to which existing deviation correcting device is changed
Into to expand its use scope.
Invention content
Problem to be solved by this invention is, in view of the problems of the existing technology, provides that a kind of cost is relatively low, bridge pier is horizontal
To reasonable stress and the bridge pier small axial dimension deviation correcting device of the larger beam body transverse direction deviation of stroke of rectifying a deviation, it is corresponding provide it is a kind of
