Abstract

The method specifically comprises the following steps that bridge parameter information is obtained, and the deviation rectifying direction, the displacement value, the vertical jacking load and the longitudinal pushing load of the pier column are determined; a deviation rectifying mechanism is at least installed on the bent cap corresponding to the pier column to be subjected to deviation rectifying and resetting, and the deviation rectifying mechanism is adopted to jack the corresponding T-shaped beam; a limiting measure is arranged at the expansion joint, and a stress releasing measure is arranged at the bottom end of the pier column; the whole body of a vertical jack is pushed through a longitudinal jack of the deviation rectifying mechanism, so that deviation rectifying and resetting are conducted on the pier column through static friction force between a base and a cover beam; when the longitudinal jack pushes the whole body of the vertical jack, the static friction force between the base and the cover beam provides counter force to rectify the deviation of the pier column, so that the damage to a bridge can be reduced to the greatest extent; in addition, the jacking height of the vertical jack can be conveniently adjusted so as to adapt to different distances between the cover beam and the diaphragm beam.

Description

Technical Field

[0001] The invention relates to the technical field of pier column deviation correction, and in particular to a method for resetting and correcting a pier column after the pier column is tilted. Background Art

[0002] Among the existing bridge structures, there are beam bridges, arch bridges, cable-stayed bridges, suspension bridges and combined structure bridges, among which beam bridges are the most common. During the construction and operation of beam bridges, the originally vertical bridge piers will show longitudinal tilt. This phenomenon is generally caused by the following reasons: (1) The plane part of the bridge is located on a super-elevated curve, the bridge deck has a large longitudinal slope, the bottom of the beam is not horizontal on the spatial curved surface, and the centripetal force (or centrifugal force) generated by vehicles running; (2) The pier is a double-column pier with a relatively large height. Under the action of the same longitudinal horizontal force component, the pier has a weaker bending resistance and is more likely to undergo longitudinal displacement. (3) Temperature effect, resulting in a "climbing" phenomenon at the support steel plate; the overall heating and cooling effects cause the beam to deflect downward in the middle of the span, while the beam end bends upward, resulting in a difference in horizontal component forces at the pier top or cap beam top. The resultant horizontal component forces point in the uphill direction, aggravating the deformation and displacement of the simply supported piers in the uphill direction. The pier top or cap beam is suppressed by the deadweight of the beam and causes irreversible residual displacement, which gradually forms traces of longitudinal cumulative displacement on the support steel plate.

[0003] At present, the conventional correction method is to add a reaction frame on the top of the cap beam, install a jack on the reaction frame, use the jack to push the main beam horizontally, and the cap beam drives the pier to reset under the reaction force. Since this method requires the installation and disassembly of the reaction frame on the cap beam, it will cause certain damage to the cap beam structure. In addition, there is a method of setting ground anchors on the ground or on the abutment, using steel wire ropes or steel strands in conjunction with through-type jacks to correct the piers, but the construction is difficult, the measures are complicated, and the construction cost is high. Summary of the invention

[0004] The purpose of the present invention is to improve and innovate the shortcomings and problems existing in the background technology, and provide a method for resetting and correcting the pier column after the pier column is tilted, which specifically includes the following steps: Obtain bridge parameter information, determine the pier column's correction direction and displacement value, as well as vertical lifting load and longitudinal thrust load; At least install a deviation-correcting mechanism on the cap beam corresponding to the pier column to be corrected and reset, and use the deviation-correcting mechanism to lift the corresponding T-beam; Set up limiting measures at the expansion joints and stress release measures at the bottom of the piers; The longitudinal jack of the deviation correction mechanism is used to push the vertical jack around, so that the static friction between the base and the cap beam can correct the deviation and reset the pier column; Among them, the correction mechanism includes a base, a vertical jack and a longitudinal jack. The upper surface of the base is slidably matched with a slider through a sliding groove, and the vertical jack is installed on the slider; the telescopic end of the vertical jack acts on the cross beam to lift the T-beam; the longitudinal jack is installed on the side wall of the base, and the telescopic end of the longitudinal jack acts on the outer surface of the vertical jack.

[0005] A further solution is that the limiting measures at the expansion joint and the stress release measures at the bottom of the pier column specifically include: Fill the expansion joint between the T-beam corresponding to the pier to be corrected and reset and its adjacent T-beam with a steel plate slider to prevent the T-beam from slipping during the correction process; The bottom part of the pier column is excavated 2-3m downwards to expose the pile foundation, and soil protection support is done well. The bottom part of the pier column refers to the side of the bottom of the pier column facing the direction of correction and reset.

[0006] A further solution is that the longitudinal jack of the correction mechanism is used to push the circumference of the vertical jack, so that the static friction between the base and the cap beam corrects the deviation and resets the pier column, which specifically includes: Control the longitudinal jack to advance a first preset distance; When the distance sensor detects that the base has slipped the first preset distance, observe whether the pier column has any abnormal phenomena such as concrete cracking; If not, the longitudinal jack continues to advance the first preset distance, and the operation is cyclically performed until the pier column offset is restored to the second preset distance; After a preset time interval, repeat the above steps until the pier column is offset and restored to the second preset distance; Repeat the above steps until the pier column is completely reset longitudinally. After observing that it is stable, backfill the soil around the bottom of the pier column. Use the same method to complete the longitudinal resetting of the remaining piers to be corrected and relocated; Wherein, a distance sensor is installed on the side wall of the base, and the distance sensor is used to monitor the sliding displacement of the base relative to the vertical jack in real time.

[0007] A further solution is that the first preset distance is 5 mm, the second preset distance is 45 mm, and the preset time is 1-2 days.

[0008] A further solution is that before the correction mechanism is used to lift the corresponding T-beam, the method further includes: A reinforcing steel plate is installed on the transverse beam, wherein the reinforcing steel plate is L-shaped and is installed on the end surface of the transverse beam away from the jacking direction and on the T-beam through anchor bolts.

[0009] A further solution is that after installing the reinforcing steel plate on the diaphragm, the method further includes: A first supporting steel plate is embedded on the telescopic end of the vertical jack, a first annular protrusion is provided at the middle of the bottom end of the first supporting steel plate, and the first supporting steel plate is sleeved on the telescopic end of the vertical jack through the first protrusion; A plurality of second supporting steel plates are nested on the telescopic end of the first supporting steel plate to adapt to the spacing between the cap beam and the diaphragm beam; Among them, the top ends of the first supporting steel plate and the second supporting steel plate are both provided with protrusions, and the lower surface of the second supporting steel plate is provided with a recessed portion matched with the protrusions.

[0010] A further solution is that the correction mechanism is installed on at least the cap beam corresponding to the pier column to be corrected and reset, and the correction mechanism is used to lift the corresponding T-beam, which specifically includes: The deviation correction mechanism is installed on the cap beam corresponding to the pier to be corrected and reset and on the cap beams corresponding to the remaining groups of piers belonging to the same T-beam; The corresponding T-beams are synchronously lifted by the vertical jacks of the correction mechanisms corresponding to the piers to be corrected and reset and the correction mechanisms corresponding to the remaining groups of piers.

[0011] A further solution is that the longitudinal jack of the correction mechanism is used to push the vertical jack around the body, which specifically includes: The longitudinal jack of the correction mechanism on the cap beam corresponding to the pier column to be corrected and reset is used to synchronously push the corresponding vertical jack.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention discloses a method for resetting and correcting the pier column after the pier column is tilted. Through the mutual cooperation of the base, the vertical jack, the longitudinal jack, the slider and the slide groove, when the longitudinal jack pushes the vertical jack, the static friction between the base and the cap beam provides a reaction force to correct the pier column, so that the pier column is restored from the tilted state to the vertical state. Since the longitudinal jack of the present application does not directly push the T-beam or the transverse beam, the damage to the T-beam and the transverse beam can be minimized as much as possible; in addition, the longitudinal jack and the vertical jack of the present application are integrated on the base, and there is no need to install and disassemble the reaction frame on the cap beam, thereby minimizing the damage to the cap beam. In addition, it is convenient to stack multiple second support steel plates on each other and on the first support steel plate, and the first support steel plate is conveniently mounted on the telescopic end of the vertical jack, so that the lifting height of the vertical jack can be adjusted to adapt to the different spacing between the cap beam and the transverse beam. Moreover, the first supporting steel plate and the second supporting steel plate are easy to assemble with each other and will not slide relative to each other after assembly. The contact area between the vertical jack and the reinforcing steel plate can also be increased, thereby making the deviation correction and jacking construction more convenient.

DETAILED DESCRIPTION

[0016] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0018] See also Figure 1-Figure 4 The present invention provides a method for resetting and correcting a pier column after the pier column is tilted, which specifically comprises the following steps: Step S1, obtaining bridge parameter information, determining the correction direction and displacement value of the pier column as well as the vertical lifting load and longitudinal thrust load; First, the parameter information of the bridge and the displacement of the pier 1 are investigated. The parameter information of the bridge includes at least the length of the pier 1, the length of the cap beam 2, the load of the T-beam 5 and the cross beam 6, etc. The displacement of the pier 1 includes the offset displacement of the top of each pier 1 relative to the bottom, so as to identify the inclination of each pier 1 and determine the correction direction and displacement value of each pier 1; then the present application performs a force analysis, and estimates the vertical jacking load and the longitudinal push load according to the deadweight and stress distribution of the T-beam 5 and the cross beam 6 structure.

[0019] It should be noted that the structure of the bridge generally includes piers 1, cap beams 2, support pedestals 3, sliding supports 4, T-beams 5 and transverse beams 6; the top of the double-column flexible pier 1 is provided with a cap beam 2, a plurality of support pedestals 3 are arranged at intervals on the upper surface of the cap beam 2, a sliding support 4 is installed on the upper end of the support pedestal 3, a T-beam 5 is arranged on the sliding support 4 and the T-beam 5 and the sliding support 4 can slide relative to each other, and the T-beams 5 are connected to each other through transverse beams 6. The cap beam 2 bears the gravity load of the T-beam 5 and the transverse beam 6, and the piers 1 on both sides of the lower surface of the cap beam 2 bear the gravity load of the cap beam 2, and the bottom end of the pier 1 is connected to the pile foundation buried in the soil.

[0020] It should be further explained that expansion joints 10 are arranged between the T-beams 5 along the direction of vehicle travel to accommodate the thermal expansion and contraction of the T-beams 5, that is, the T-beams 5 are arranged in multiple sections along the direction of vehicle travel; multiple pairs of double piers 1 are arranged under each section of the T-beam 5, and the multiple pairs of double piers 1 jointly bear the gravity load of the T-beams 5 of the corresponding section.

[0021] Step S2, installing a correction mechanism on at least the cap beam corresponding to the pier column to be corrected and reset, and using the correction mechanism to lift the corresponding T-beam; In this embodiment, the deviation correction mechanism 11 includes a base 111, a vertical jack 114 and a longitudinal jack 117. The four corners of the upper end of the base 111 are provided with lifting rings 115 to facilitate hanging the base 111 on the cap beam 2. The upper surface of the base 111 is slidably matched with a slider 113 through a slide groove 112, and the vertical jack 114 is installed on the slider 113; the telescopic end of the vertical jack 114 acts on the transverse beam 6 to lift the T-beam 5. In addition, the base 111 is L-shaped, and the longitudinal jack 117 is installed on the side wall of the base 111. The telescopic end of the longitudinal jack 117 acts on the outer surface of the vertical jack 114.

[0022] It should be noted that the vertical jack 114 acts in the vertical direction, while the longitudinal jack 117 acts in the longitudinal direction, wherein the vertical direction is the vertical direction of the pier 1, and the longitudinal direction is the vehicle travel direction of the bridge. Since the pier 1 to be corrected and reset needs to be pushed and reset, the correction mechanism 11 needs to be installed at least on the cap beam 2 corresponding to the pier 1 to be corrected and reset, and in order to smoothly lift the T-beam 5, the present application can also install the correction mechanism 11 on the cap beam 2 corresponding to the remaining piers 1 corresponding to the T-beam 5, and the vertical jack 114 of the correction mechanism 11 jointly lifts the T-beam 5; after lifting the T-beam 5, the T-beam 5 is separated from the sliding support 4, and the gravity load of the T-beam 5 is loaded on the vertical jack 114, and then loaded on the base 111.

[0023] It should be further explained that if the vertical stiffness of the bridge's transverse beam 6 is insufficient to withstand the vertical thrust and the longitudinal stiffness is insufficient to withstand the horizontal thrust, the present application can first reinforce the transverse beam 6 and then use the vertical jack 114 to lift the T-beam 5. Among them, the method of reinforcing the transverse beam 6 can be to install a reinforcing steel plate 7, which is L-shaped and is installed on the end face of the transverse beam 6 away from the jacking direction and on the T-beam 5 through anchor bolts 8.

[0024] Step S3, setting limiting measures at the expansion joint and setting stress release measures at the bottom end of the pier column; In order to avoid longitudinal displacement of the T-beam 5 during the deviation correction project, the present application adds a limiting measure at the expansion joint 10 between the T-beam 5 corresponding to the pier 1 to be corrected and reset and the adjacent T-beam 5 to prevent the beam body from sliding. Specifically, the present application fills the expansion joint 10 with a steel plate slider 9 to prevent the T-beam 5 from longitudinal displacement during the deviation correction and reset process.

[0025] Furthermore, in order to ensure that stress dissipation plays the maximum value, the bottom end of pier 1 is partially excavated 2-3m downward to expose the pile foundation, and soil protection support is done well. The bottom end of pier 1 refers to the side of the bottom end of pier 1 facing the direction of correction and reset.

[0026] Step S4, using the longitudinal jack of the correction mechanism to push the circumference of the vertical jack, so that the static friction between the base and the cap beam corrects the deviation and resets the pier column; Specifically, after setting limiting measures at the expansion joint 10 and setting stress release measures at the bottom end of the pier 1, the longitudinal jack 117 of the present application pushes the circumference of the vertical jack 114, and the pushing force reacts on the longitudinal jack 117. Since the longitudinal jack 117 is installed on the base 111, the base 111 will be driven to slide relative to the longitudinal jack 117. Since the gravity load of the cap beam 2 is loaded on the base 111, the static friction between the base 111 and the cap beam 2 is sufficient to correct the deviation and reset the pier 1; therefore, after the longitudinal jack 117 pushes the circumference of the vertical jack 114, the static friction between the base 111 and the cap beam 2 provides a reaction force to correct the deviation, so that the pier 1 is restored from an inclined state to a vertical state.

[0027] It should be noted that the longitudinal jack 117 of the present application pushes the circumference of the vertical jack 114, rather than the longitudinal jack 117 directly pushing the T-beam 5 and the cross beam 6, thereby minimizing the damage to the T-beam 5 and the cross beam 6 as much as possible; in addition, the longitudinal jack 117 and the vertical jack 114 of the present application are both integrated on the base 111, and there is no need to install and disassemble the reaction frame on the cap beam 2, thereby minimizing the damage to the cap beam 2 as much as possible.

[0028] In addition, in the process of the longitudinal deviation correction and jacking construction of the pier column 1, in order to avoid damage to the pier column 1 and the pile foundation, in this embodiment, a distance sensor 116 is installed on the side wall of the base 111, and the sliding displacement of the base 111 relative to the vertical jack 114 is monitored in real time by the distance sensor 116; and the longitudinal jack 117 is controlled to slowly return oil through the monitored sliding displacement; Specifically, the longitudinal deviation correction and jacking construction process of the pier column 1 is as follows: Step S41, controlling the longitudinal jack 117 to advance a first preset distance; Step S42, when the distance sensor 116 detects that the base 111 slides a first preset distance, observe whether the pier 1 has abnormal phenomena such as concrete cracking; Step S43: If not, the longitudinal jack 117 continues to advance the first preset distance, and the operation is cyclically performed until the pier column 1 is deflected and restored to the second preset distance; Step S44, after a preset time interval, repeat steps S41-S43 until the pier 1 is deflected and restored to a second preset distance; Step S45, repeating steps S41-S44 until the pier 1 completes longitudinal resetting, and after being observed to be stable, backfilling the soil around the bottom of the pier 1; Step S46, using the same method to complete the longitudinal resetting of the remaining piers 1 to be corrected and relocated.

[0029] Among them, the first preset distance may be 5 mm, the second preset distance may be 45 mm, and the preset time may be 1-2 days.

[0030] In the embodiment of the present invention, the lifting height of the vertical jack 114 can also be adjusted to adapt to the different spacings between the cap beam 2 and the transverse beam 6. Specifically, a first supporting steel plate 118 is nested on the telescopic end of the vertical jack 114, and a first annular protrusion 1181 is provided at the middle of the bottom end of the first supporting steel plate 118. The first supporting steel plate 118 is sleeved on the telescopic end of the vertical jack 114 through the first protrusion 1181. A plurality of second supporting steel plates 119 are nested on the telescopic end of the first supporting steel plate 118. The tops of the first supporting steel plate 118 and the second supporting steel plate 119 are both provided with protrusions 120, and the lower surface of the second supporting steel plate 119 is provided with a recessed portion 121 adapted to the protrusion 120. Through the cooperation between the raised portion 120 and the recessed portion 121, it is convenient to stack multiple second support steel plates 119 on each other and on the first support steel plate 118, so that the lifting height of the vertical jack 114 can be extended to adapt to the different spacings between the cap beam 2 and the diaphragm beam 6. In addition, the first support steel plate 118 and the second support steel plate 119 are easy to assemble with each other, and will not slide relative to each other after assembly, and the contact area between the vertical jack 114 and the reinforcing steel plate 7 can be increased, so that the deviation correction and jacking construction is more convenient.

[0031] In summary, the present invention discloses a method for resetting and correcting a pier column after the pier column is tilted. Through the mutual cooperation of the base 111, the vertical jack 114, the longitudinal jack 117, the slider 113 and the slide groove 112, when the longitudinal jack 117 pushes the vertical jack 114, the static friction between the base 111 and the cap beam 2 provides a reaction force to correct the pier column 1, so that the pier column 1 is restored from an inclined state to a vertical state. Since the longitudinal jack 117 of the present application does not directly push the T-beam 5 or the cross beam 6, the damage to the T-beam 5 and the cross beam 6 can be minimized as much as possible; in addition, the longitudinal jack 117 and the vertical jack 114 of the present application are both integrated on the base 111, and there is no need to install and disassemble the reaction frame on the cap beam 2, thereby minimizing certain damage to the cap beam 2 as much as possible. In addition, it is convenient to stack multiple second support steel plates 119 on each other and on the first support steel plate 118, and the first support steel plate 118 is conveniently mounted on the telescopic end of the vertical jack 114, so that the lifting height of the vertical jack 114 can be adjusted to adapt to the different spacings between the cap beam 2 and the diaphragm beam 6. Moreover, the first support steel plate 118 and the second support steel plate 119 are convenient to assemble with each other, and will not slide relative to each other after assembly, and can also increase the contact area between the vertical jack 114 and the reinforcing steel plate 7, so that the deviation correction and jacking construction is more convenient.
