Abstract
The invention discloses a pier stud rectification technique, relates to a bridge construction technology, and can be used for efficiently performing construction operation in a systematic manner. According to the technique provided by the invention, the safety is high, the construction period is short and high in controllability, emergent treatment engineering can be effectively handled, and such damage can be effectively solved from the root; the construction cost is reduced, the operability is high, and only an emergency lane is occupied for construction, so that traffic is not affected.
Description
Technical field
The present invention relates to a kind of bridge construction technique, particularly relate to a kind of pier stud correction process.
Background technology
Prior art usually occurring, version is T beam or small box girder formula bridge, draws because of pinner injustice, bearing deformation etc.
Play pier stud displacement deviation.For skew pier stud pushing tow is corrected, need a kind of high complete reliable, the process of strong operability.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide a kind of high complete reliable,
The pier stud correction process of strong operability.
For achieving the above object, the invention provides a kind of pier stud correction process, sequentially include the following steps:
Step 1, monitoring disease bridge all pier studs perpendicularity；
Gate-type hanger is set up on step 2, bent cap；
Step 3, inclinator repetition measurement disease pier stud side-play amount；
Step 4, measure and design wedge-shaped steel plate and pinner size；
Step 5, release spacing；
The monitoring of step 6, bridge jacking, beam body jacking, former bearing are removed, weld wedge-shaped steel plate, are adjusted pinner height；
Step 7, installation wedge-shaped steel plate also carry out preservative treatment, brushing silicone grease oil to it, lay interim sliding bearing；
Step 8, test constantly disease pier stud perpendicularity；
Reaction frame is installed on step 9, bent cap；
Step 10, mount stress, deformation monitoring system；
Step 11, installation pushing tow equipment；
Step 12, equipment debugging；
Step 13, calculating correction displacement；
Step 14, record the initial data at each monitoring position；
Step 15, inspection bearing and support centerline deviation theoretical perpendicularity of rectifying a deviation；
New bearing is installed in step 16, jacking.
Carry out in the following manner it is also preferred that the left described step 7 carries out preservative treatment to wedge-shaped steel plate: on described wedge-shaped steel plate
Brushing zinc silicate priming paint 70 μm；Brushing epoxy polyamide priming paint 25 μm on described zinc silicate priming paint；At described epoxy polyamide
Brushing epoxy-mica ferrum oxide 75 μm on priming paint；Described epoxy-mica ferrum oxide is brushed the first poly-ammonia methyl formate top coat layer
40μm；Described first poly-ammonia methyl formate top coat layer is brushed the second poly-ammonia methyl formate top coat layer 40 μm.
It is also preferred that the left the step of pier stud perpendicularity situation of change after also including persistently monitoring correction.
The invention has the beneficial effects as follows: the present invention can efficiently, architecture construction operation；Safety of the present invention is high, construction
Duration short controllability is strong, and reply emergent punishment engineering is highly effective, and the present invention can the most fundamentally solve this type of disease；
The present invention saves construction cost, workable, and the present invention only takes up Emergency Vehicle Lane construction, does not affect traffic and passes through.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
Pier stud tilts and bearing sliding, and reason of searching to the bottom is that on bearing, pre-embedded steel slab not level causes, therefore emergent place
Put the engineering most important thing to be the design of wedge-shaped steel plate on bearing, lay.Pier stud tilts and bearing sliding is still in development, therefore exists
The vertical misalignment amount (in particular for the bridge pier of correction) of the front all bridge piers of reply bridge carries out repetition measurement, to determine the front bridge pier of construction
Accurate offset value, so that it is determined that the correction value of bridge pier.
During deviation rectification, tackle main force part (bottom T beam diaphragm plate and bridge pier) and carry out disease monitoring.Correction
Before should remove old bearing, shelve wedge-shaped steel plate ensure the upper and lower level of bearing, lay temporary support (ensure the least the rubbing of bearing
Wipe coefficient, without detrusion during correction, convenient correction).The present invention provides a kind of pier stud correction work based on above thinking
Process, sequentially includes the following steps:
Step 1, employing total powerstation monitoring disease bridge all pier studs perpendicularity；
Gate-type hanger is set up on step 2, bent cap；
Step 3, inclinator repetition measurement disease pier stud side-play amount；
Step 4, measure and design wedge-shaped steel plate and pinner size；
Step 5, release spacing；
The monitoring of step 6, bridge jacking, beam body jacking, former bearing are removed, weld wedge-shaped steel plate, are adjusted pinner height；
Step 7, installation wedge-shaped steel plate also carry out preservative treatment, brushing silicone grease oil to it, lay interim sliding bearing；
Step 8, test constantly disease pier stud perpendicularity, until observing to offseting no longer self-recovery；
Reaction frame is installed on step 9, bent cap；
Step 10, mount stress, deformation monitoring system；
Step 11, installation pushing tow equipment；
Step 12, equipment debugging；
Step 13, calculating correction displacement；
Step 14, record the initial data at each monitoring position；
Step 15, inspection bearing and support centerline deviation correction to theoretical perpendicularity or rebound to an equilibrium-like
State；
Step 16, monitoring are checked, persistently pier stud perpendicularity situation of change after monitoring correction；
New bearing is installed in step 17, jacking.
Described step 7 carries out preservative treatment to wedge-shaped steel plate and carries out in the following manner: brushing silicon on described wedge-shaped steel plate
Acid zinc bottom paint 70 μm；Brushing epoxy polyamide priming paint 25 μm on described zinc silicate priming paint；On described epoxy polyamide priming paint
Brushing epoxy-mica ferrum oxide 75 μm；Described epoxy-mica ferrum oxide is brushed the first poly-ammonia methyl formate top coat layer 40 μm；
Described first poly-ammonia methyl formate top coat layer is brushed the second poly-ammonia methyl formate top coat layer 40 μm.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art without
Need creative work just can make many modifications and variations according to the design of the present invention.Therefore, all technology in the art
Personnel are available by logical analysis, reasoning, or a limited experiment the most on the basis of existing technology
Technical scheme, all should be in the protection domain being defined in the patent claims.
