Abstract
The utility model discloses a micro jacking and beam-moving device. The micro jacking and beam-moving device comprises a first vertical jack, a first vertical jack and a horizontal jack. A chute is composed of an integrated chute base plate and a chute end plate. The first vertical jack is disposed on the base plate of the chute. A contact surface of the chute base plate is a mirror surface stainless steel plate. The bottom end of the first vertical jack is a polyfluortetraethylene plate. The mirror surface stainless steel plate and the polyfluortetraethylene plate are arranged in a sliding mode. Steel backing plates are arranged between the piston ends of the first vertical jack and the second vertical jack and a beam body. The micro jacking and beam-moving device is aimed at correcting and resetting the route offset so that requirement of acceptance standard of high speed railway track engineering is satisfied.
Description
Technical field
The utility model relates generally to the bridge correction and processes, and more specifically says to be applied in the traversing a kind of device of bridge.
Background technology
Ningbo-Hangzhou high ferro Qinhuaihe River grand bridge is designed to (40+64+40) m continuous beam across top, eastern Qi road, adopts the construction of support cast-in-place method.12 meters of continuous beam bridge deck widths, 3.05 meters～6.05 meters of deck-moldings.Be designed to CRTS II plate-type non-fragment orbit on bridge, design speed per hour 350km.Be subjected to circuit left side expressway ramp roadbed filling and ring road wet spraying pile construction infection, bridge pier shaft generation off normal, the offset direction is for to the right.Show according to rail accurate adjustment measurement result, ballastless track on bridge circuit deviant peak value to the right is 14.4mm.
For above problem, in prior art, many employings are poured into processing after taking off plate again, yet during this scheme implementation, combined test is about to begin, need to carry out rail stress in construction and diffuse, saw the operations such as rail, track plates bar planting anchoring, wide seam cut, contact net power failure, need the specialty of cooperation and unit more, and the engineering time is longer, larger on the impact of combined test duration, construction cost can improve 4,000,000 yuan.
The utility model content
The utility model purpose is to provide a kind of little jacking Beam shifter, resets for stitch seam leans out line is corrected, to satisfy high speed railway track acceptance on examination standard-required.
The utility model is achieved through the following technical solutions:
Little jacking Beam shifter, be included in the first vertical jack, the second vertical jack, the horizontal direction jack that arrange between beam body and pier shaft, described chute is made of the chute base plate that one is arranged, chute end plate, the first vertical jack is placed on the chute base plate of chute, the contact surface of chute base plate is the mirror face stainless steel plate, the bottom of the first vertical jack is polyfluortetraethylene plate, mirror face stainless steel plate and polyfluortetraethylene plate slide and arrange, and are provided with billet between the piston end of the first vertical jack, the second vertical jack and beam body.
The top of the described first vertical jack, the second vertical jack is respectively equipped with a sphere and contacts in the beam body.
Before translation, need first jack-up construction due to bridge, utilize the pushing reaction of the frictional resistance equilibrium level jack of vertical jack, thereby avoid the counterforce device of constructing.
Operating principle of the present utility model: before jacking, remove the bearing constraint, utilize first, second vertical jack with the beam body jacking 3mm that makes progress, make the disengaging of case beam and bridge pier.The horizontal positioned jack is fixed on the chute end plate, apply the thrust of horizontal direction by level jack, the required frictional resistance of counter-force bottom pier shaft and chute of level jack work provides, and makes beam body and pier shaft generation relative sliding, reaches the purpose of moving beam.
The utility model has the advantages that:
The first, jacking, translation all need not construct counter-force platform and reaction frame, dismounting counter-force platform and reaction frame after this has also been avoided construction to complete; Quick construction economizes on resources.
The second, by using new material and control the jacking amount in the smaller value scope in translating device, reduced the damage of translation construction to girder construction, strengthened the safety of structure translation.
The 3rd, adopt hierarchical loading, the measure of substep translation has reduced the impact of translation construction on the ballastless track on bridge structure to greatest extent.
The 4th, during construction, can be without traffic control on bridge floor, the construction of translation has simultaneously dropped to minimum on the impact of the traffic of road under bridge face and surrounding environment.
The 5th, short construction period is for the time has been striven in combined test, for unit has saved great amount of cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is chute plan view of the present utility model.
The specific embodiment
referring to Fig. 1, little jacking Beam shifter, be included in the first vertical jack 1 that arranges between beam body and pier shaft, the second vertical jack 2, horizontal direction jack 3, chute 4 is by the chute base plate 5 that one is arranged, chute end plate 6 consists of, the first vertical jack 1 is placed on the chute base plate 5 of chute 4, the contact surface of chute base plate 5 is the mirror face stainless steel plate, the bottom of the first vertical jack 1 is polyfluortetraethylene plate, mirror face stainless steel plate and polyfluortetraethylene plate slide and arrange, the first vertical jack 1, be provided with billet 8 between the piston end of the second vertical jack 2 and beam body 7, the first vertical jack, the top of the second vertical jack is respectively equipped with a sphere and contacts in the beam body.
The chute base plate is that the 10mm steel plate is made, and side plate is the 12mm steel plate, and end plate is the 40mm steel plate.End plate is opened diameter 100mm circular hole and is used for installing the fixed level jack.Between steel plate and steel plate, welding links, side plate outsourcing end plate and base plate, right angle welding seam.
Referring to Fig. 2, the chute internal orifice is wide consistent with the jack width, to limit vertical jack moving direction.Before translation, at chute inwall coating butter to reduce frictional resistance.
Chute base plate bottom surface is through coarse processing, to increase frictional force.
According to the translation desired value, carry out stage by stage translation.General per stage shift value is no more than 3mm.After translation puts in place, fix bearing, slowly lay down vertical jack, remove translating device, move beam and complete.
