Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge pier reinforcement, in particular to a reinforced bridge pier and a reinforced bridge. Background Art
[0002] Please refer to Figure 1 and Figure 2 In the process of constructing a ship lock attached to an existing bridge, it is necessary to construct under the original bridge. First, the original riverbed needs to be deepened to dig out the required waterway. When constructing the waterway, the piers on both sides of the waterway will be partially exposed, causing the depth of the piers buried in the rock to become shallower. Although backfilling will be carried out in the subsequent construction process, the rock environment around the existing piers will be changed after excavation. In the subsequent construction process, the existing piers will sink or tilt over time, posing a major safety hazard.
[0003] In summary, there is an urgent need for a reinforced bridge pier and a reinforced bridge to solve or at least partially solve the problems existing in the prior art. Utility Model Content
[0004] The utility model aims to provide a reinforced bridge pier, aiming to solve the problem of weakened structural stability of existing bridge piers after channel excavation. The specific technical solution is as follows:
[0005] A reinforced bridge pier comprises an existing bridge pier, a reinforced pier group, a first reinforced cap and a second reinforced cap. The existing bridge pier has an existing pile foundation and an existing cap. Two reinforced pier groups are provided and are respectively arranged on both sides of the existing bridge pier. The first reinforced cap extends along the width direction of the existing cap and is erected on the two reinforced pier groups. The first reinforced cap covers the existing pile foundation arrangement. The first reinforced cap is provided with a sink for supporting the existing cap.

[0007] Furthermore, the embedded reinforcement is arranged in a bent shape in the first reinforcement base.
[0008] Furthermore, the existing foundation is partially embedded in the trough, and a cooling structure is provided in the first reinforced foundation. The cooling structure includes a cooling water pipe, which is S-shaped and wound inside the first reinforced foundation. One end of the cooling water pipe is a water inlet, and the other end of the cooling water pipe is a water outlet.

[0009] Furthermore, a temperature measuring structure is provided in the first reinforcement base, and the temperature measuring structure includes a temperature measuring tube, one end of the temperature measuring tube extends into the first reinforcement base, and the other end of the temperature measuring tube extends out of the first reinforcement base.
[0010] Furthermore, the reinforcement pier group includes at least two reinforcement pile foundations, the two reinforcement pile foundations are arranged along the length direction of the existing foundation, the two groups of reinforcement pier groups are relatively arranged on both sides of the width direction of the existing foundation, and the first reinforcement foundation is erected on four reinforcement pile foundations.
[0011] Furthermore, the reinforced pile foundation includes a steel cage and concrete. The steel cage includes main bars arranged along the length direction of the reinforced pile foundation. A strong straight threaded joint is provided between two adjacent main bars on the same straight line. The two adjacent main bars are fastened and connected by the strong straight threaded joint.

[0012] Furthermore, a plurality of main bars are arranged along the circumference of the steel cage, and the straightened threaded joints on the plurality of main bars are arranged staggered with each other.

[0015] The application of the technical solution of the utility model has the following beneficial effects:
[0016] When constructing the waterway, the existing pile foundations and existing caps of the existing piers will leak out during the process of excavating the waterway.

DETAILED DESCRIPTION
[0032] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below, and preferred embodiments of the present invention are given. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. 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.
[0034] Embodiment 1:
[0035] See also Figure 3-Figure 11 This embodiment provides a reinforced bridge pier 6, including an existing bridge pier 1, a reinforced pier group 2, a first reinforced cap 3 and a second reinforced cap 4. The existing bridge pier 1 has an existing pile foundation 14 and an existing cap 11. The reinforced pier group 2 is provided with two groups and is respectively arranged on both sides of the existing bridge pier 1. The first reinforced cap 3 extends along the width direction of the existing cap 11 and is erected on the two reinforced pier groups. The first reinforced cap 3 covers the existing pile foundation 14. The first reinforced cap 3 is provided with a sink 31 for supporting the existing cap 11. The second reinforced cap 4 is erected on the two reinforced pier groups 2. The second reinforced cap 4 is located below the first reinforced cap 3 and covers the existing pile foundation 14. It should be noted that the width direction of the existing cap 11 is along the bridge direction, and the length direction of the existing cap 11 is transverse to the bridge direction.
[0036] Specifically, the reinforcement pier groups 2 are arranged on both sides along the transverse direction of the bridge, and the existing caps 11 are partially embedded in the sinking grooves 31. The depth of the existing caps 11 embedded in the sinking grooves 31 of the second reinforcement caps 4 accounts for half of the thickness of the existing caps 11, so that the existing caps 11 can be firmly connected to the second reinforcement caps 4, so that the existing caps 11 are firmly embedded on the second reinforcement caps 4. The depth of the sinking grooves 31 on the second reinforcement caps 4 accounts for one-third of the thickness of the second reinforcement caps 4, so that the bottom of the sinking grooves 31 of the second reinforcement caps 4 has sufficient thickness to prevent the second reinforcement caps 4 from breaking from the sinking grooves 31 due to force.
[0037] It is understandable that when constructing the waterway, the existing pile foundation 14 and the existing cap 11 of the existing pier 1 will leak out during the process of digging the waterway. By arranging the reinforcement pier group 2 around the existing pier 1, the reinforcement pier group 2, the first reinforcement cap 3 and the second reinforcement cap 4 are used to provide auxiliary support to the existing pier 1. The force on the existing pier 1 is transmitted to the first reinforcement cap 3 through the sinking trough 31. The first reinforcement cap 3 transmits the force to the rock layer through the reinforcement pier group 2, so that the existing pier 1, the reinforcement pier group 2, the first reinforcement cap 3 and the second reinforcement cap 4 form a whole. The whole increases the supporting contact area with the rock layer, so that the reinforced reinforced pier 6 is not easy to sink and tilt under gravity, thereby increasing the stability of the existing pier 1. The second reinforcement cap 4 is used to connect the middle part of the existing pier 1 and the two reinforcement pier groups 2, improve the integrity of the existing pier 1 and the two reinforcement pier groups 2, make them bear force in coordination, and improve the ability to resist sinking and tilting. The thickness of the second reinforcement pedestal 4 is less than that of the first reinforcement pedestal 3. On the one hand, the first reinforcement pedestal 3 needs to be grooved on it, and secondly, the first reinforcement pedestal 3 needs to bear the downward pressure of the existing pedestal 11. Therefore, the first reinforcement pedestal 3 needs to have sufficient rigidity to bear heavier weight, while the second reinforcement pedestal 4 mainly plays a connecting role and needs to bear relatively small forces. Therefore, the second reinforcement pedestal 4 can be thinner than the first reinforcement pedestal 3 to reduce the amount of steel bars and concrete 212 under the premise of meeting the use requirements, so as to save some costs. At the same time, the two groups of reinforcement pier groups 2 and the existing pile foundation 14 of the existing bridge pier 1 are connected together through the second reinforcement pedestal 4, so that the whole is subjected to force, thereby improving the overall force-bearing capacity.
[0038] Furthermore, a plug hole 12 is arranged on the existing bridge pier 1, one end of the embedded steel bar 32 extends into the plug hole 12, and the other end of the embedded steel bar 32 is buried in the first reinforced pedestal 3, and a glue layer 13 is filled between the embedded steel bar 32 and the inner wall of the plug hole 12. It can be understood that when constructing the first reinforced pedestal 3, the plug hole 12 is first drilled on both sides of the existing pedestal 11 of the existing bridge pier 1. It should be noted that before drilling, a steel bar detector can be used to detect the position of the steel bars at the embedded steel bar 32 of the bridge component, or the protective layer can be chiseled off to expose the steel bars. If there are steel bars at the hole position of the embedded steel bar 32, the drilling position should be adjusted appropriately. When encountering steel bars or embedded parts during drilling construction, drilling should be stopped immediately, and the drilling position should be moved appropriately; the drilling depth is about 1 / 4 to 1 / 2 of the length of the embedded steel bar 32, and 1 / 3 is taken here. After drilling the plug hole 12, the plug hole 12 and the anchor bar 32 need to be cleaned, and glue is injected into the plug hole 12. It should be noted that when injecting glue, it is necessary to start from the bottom of the plug hole 12 to prevent bubbles from being generated after the anchor bar 32 is inserted. Then the anchor bar 32 is inserted. When the straight bar is inserted, the anchor bar 32 is located at the center of the plug hole 12, even if the anchor bar 32 is coaxially arranged with the plug hole 12, so that the glue thickness outside the anchor bar 32 is the same. After the glue solidifies, a glue layer 13 is formed, and the glue layer 13 firmly fixes the anchor bar 32 in the plug hole 12.
[0039] Furthermore, the anchor bar 32 is arranged in a bent shape inside the first reinforced base 3, and one end of the bend extends into the first reinforced base 3. After the first reinforced base 3 is poured with concrete 212, the end of the anchor bar 32 away from the existing base 11 is firmly fixed inside the first reinforced base 3, and the existing base 11 and the first reinforced base 3 are tightly connected through the anchor bar 3.
[0040] Furthermore, a cooling structure 33 is installed in the first reinforced pedestal 3. The cooling structure 33 includes a cooling water pipe 331. The cooling water pipe 331 is arranged in an S shape inside the first reinforced pedestal 3. One end of the cooling water pipe 331 is a water inlet, and the other end of the cooling water pipe 331 is a water outlet. Both the water outlet and the water inlet extend from the side wall of the first reinforced pedestal 3. Specifically, the cooling structure 33 is arranged in multiple layers. The multiple layers of cooling structures 33 are evenly arranged along the thickness direction of the first reinforced pedestal 3. Each layer of cooling structure 33 includes one or two cooling water pipes 331. The same cooling water pipe 331 is evenly and circuitously arranged to form a layer. Of course, the same cooling structure 33 is also arranged in the second reinforced pedestal 4 to cool and control the temperature of the second reinforced pedestal 4. It can be understood that in the process of pouring concrete 212 and curing concrete 212, in order to prevent the temperature inside the poured concrete 212 from being too high, cooling water is input through the water inlet of the cooling water pipe 331, so that the cooling water flows along the cooling water pipe 331 and is discharged from the water outlet. When the cooling water flows in the cooling water pipe 331, the temperature inside the concrete 212 is taken away, thereby preventing the temperature inside the concrete 212 from being too high. On the other hand, by inputting cooling water into the cooling water pipe 331, the inside of the concrete 212 and the surface of the concrete 212 are kept basically consistent, preventing the temperature difference between the inside of the concrete 212 and the surface of the concrete 212 from being too high. Too high a temperature difference will cause tensile stress inside the concrete 212, thereby causing the generation of expansion cracks, which will seriously affect the mechanical properties of the concrete 212. Therefore, controlling the temperature difference between the inside and outside of the poured concrete 212 is conducive to preventing the generation of expansion cracks.
[0041] Furthermore, a temperature measuring structure 34 is provided in the first reinforcement base 3, and the temperature measuring structure 34 includes a temperature measuring tube 341, one end of the temperature measuring tube 341 extends into the first reinforcement base 3, and the other end of the temperature measuring tube 341 extends out of the first reinforcement base 3. It can be understood that when pouring concrete 212 and curing concrete 212, a thermometer is inserted from the temperature measuring tube 341 to measure the temperature inside the concrete 212, so as to determine whether it is necessary to input cooling water from the cooling structure 33 for cooling based on the measured temperature. A plurality of temperature measuring tubes 341 are arranged on the first reinforcement base 3, and the plurality of temperature measuring tubes 341 are arranged vertically. In other embodiments, the temperature measuring tubes 341 can also be arranged horizontally, or in a combination of vertical and horizontal arrangements.
[0042] Further, the reinforcement pier group 2 includes two reinforcement pile foundations 21, and the two reinforcement pile foundations 21 are arranged along the length direction of the existing cap 11. It should be noted that the length direction of the existing cap 11 is the transverse direction of the bridge, and two reinforcement pier groups 2 are provided. The two groups of reinforcement pier groups 2 are relatively arranged on both sides of the width direction of the existing cap 11, and the first reinforcement cap 3 is erected on four reinforcement pile foundations 21. By arranging the two reinforcement pile foundations 21 along the length direction of the existing cap 11, the resistance to the collapse of the existing cap 11 along the length direction is strengthened, and the stability of the existing cap 11 along the length direction is enhanced; by arranging the two groups of reinforcement pile foundations 21 along the width direction of the existing cap 11, the resistance to the collapse of the existing cap 11 along the width direction is strengthened, and the stability of the existing cap 11 along the width direction is enhanced. Of course, in other embodiments, each reinforcement pier group 2 may also include three reinforcement pile foundations 21, or more reinforcement pile foundations 21; the reinforcement pier group 2 may also be provided with three or more groups.
[0043] Furthermore, the reinforced pile foundation 21 includes a steel cage 211 and concrete 212. The steel cage 211 includes main bars 2111 arranged along the length direction of the reinforced pile foundation 21. A strong straight threaded joint 2112 is provided between two adjacent main bars 2111 on the same straight line. The two adjacent main bars 2111 are fastened together by the strong straight threaded joint 2112. A portion of the concrete 212 is wrapped around the outside of the steel cage 211, and the thickness of the outer concrete 212 is not less than 2.5 cm to protect the steel cage 211 and prevent the steel cage 211 from directly contacting the groundwater and causing rust and damage. The other portion of the concrete 212 is filled inside the steel cage 211. Specifically, a plurality of main bars 2111 are evenly distributed along the circumference of the steel cage 211, and stirrups are also connected to the outside of the main bars 2111, which are welded to the main bars 2111. One end of the straightened threaded joint 2112 is a left-handed thread, and the other end is a right-handed thread. The main bars 2111 near the left-handed thread end of the straightened threaded joint 2112 are also provided with left-handed threads, and the main bars 2111 near the right-handed thread end of the straightened threaded joint 2112 are provided with right-handed threads. When matching, it is only necessary to rotate the straightened threaded joint 2112 to simultaneously connect with the main bars 2111 at both ends of the straightened threaded joint 2112. Two adjacent main bars 2111 on the same axis are connected in a threaded manner through the straightened threaded joint 2112, so that the two main bars 2111 are tightly connected together. It should be noted that between two circumferentially adjacent main bars 2111, the straightened threaded joints 2112 are staggered to avoid arranging the straightened threaded joints 2112 in the same horizontal plane. Relatively speaking, the connection strength at the strong straight threaded joint 2112 is relatively weak, or defects may occur. If arranged in the same plane, the strength of this connection will be weaker than the rest of the reinforced pile foundation 21, and there is a risk of breaking at this location. The staggered arrangement can avoid this situation to a certain extent.
[0044] Furthermore, an acoustic detection tube 213 is provided in the reinforced pile foundation 21, and the acoustic detection tube 213 is arranged parallel to the axial direction of the reinforced pile foundation 21, one end of the acoustic detection tube 213 extends to the lower part of the reinforced pile foundation 21, and the other end extends from the top of the reinforced pile foundation 21, and three acoustic detection tubes 213 are arranged along the circumference of the reinforced pile foundation 21. In other embodiments, four or more acoustic detection tubes 213 can also be arranged. It can be understood that after the concrete 212 is poured into the reinforced pile foundation 21, the reinforced pile foundation 21 is ultrasonically detected through the acoustic detection tube 213 to determine whether there are casting defects such as cavities in the reinforced pile foundation 21; if there are casting defects, the location of the casting defect can be determined, and the side wall of the acoustic detection tube 213 is broken from the location, so that the acoustic detection tube 213 is connected to the defect, and mortar is poured through the acoustic detection tube 213, so that the defect is filled, thereby playing a role in detecting and repairing the casting defect.
[0045] The technical effects of the utility model are as follows: by adopting the reinforced pier group 2, the first reinforced pedestal 3 and the second reinforced pedestal 4, the stability of the existing bridge pier 1 is strengthened, the existing bridge is prevented from settling or deflecting after the waterway is built, and the stability of the existing bridge during the later use is improved.
[0046] By adopting the method of embedding reinforcement 32, the connectivity between the existing pedestal 11 of the existing pier 1 and the newly built first reinforced pedestal 3 is improved, thereby improving the integrity of the connection between the existing pier 1 and the reinforced pier group 2, the first reinforced pedestal 3 and the second reinforced pedestal 4, and improving the stability performance.
[0047] By adopting the cooling structure 33 to cool the first reinforcement base 3, the temperature of the first reinforcement base 3 is prevented from being too high during casting and curing, which may cause the properties of the concrete 212 to change, so that the cast concrete 212 can obtain better mechanical properties.
[0048] By using a detection device to detect the internal temperature of the first reinforcement base 3 and working in coordination with the cooling structure 33, it is ensured that the internal and external temperatures of the first reinforcement base 3 are accurately controlled to prevent expansion cracks caused by excessive temperature differences between the inside and outside.
[0049] Embodiment 2:
[0050] See also Fig.12The utility model also provides a reinforced bridge, including a bridge deck beam span 5 and the above-mentioned reinforced bridge piers 6. A plurality of reinforced bridge piers 6 are arranged in a direction perpendicular to the waterway, and the bridge deck beam span 5 is overlapped on the top of the reinforced bridge piers 6 in sequence. The bridge deck beam span 5 is supported by the reinforced bridge piers 6, and the reinforced bridge piers 6 directly strengthen the foundation of the bridge pier, so that the reinforced bridge piers 6 have a stronger bearing capacity than other bridge piers, and the structure does not need to make a lot of changes to the existing bridge piers 1 during construction, and the construction can continue on the original basis. The structure is not only suitable for the situation of renovating the waterway at the existing bridge, but also suitable for the renovation of other bridges.
[0051] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
