Description
Technical Field
[0001] The present application relates to the technical field of continuous beam construction, and in particular to a double-line continuous beam hanging basket. Background Art
[0002] Double-line connecting beam hanging basket refers to a method of cantilever pouring construction using the hanging basket method. The hanging basket method, also known as cantilever pouring construction, is a common technology in the construction of prestressed concrete continuous beams. Its basic principle is to use brackets on both sides of the pier to support and pour a certain length of beam segment. This segment is the zero bridge, and the hanging basket is used to symmetrically pour concrete on both sides segment by segment. After the concrete reaches the specified strength, the prestressed steel strands are tensioned, and then the hanging basket is moved to the next segment for a cycle operation until it is closed.
[0003] At present, the construction method of the connecting beam hanging basket is to place the truss (diamond truss or triangular truss, etc.) on the track of the zero bridge, hang the hanging basket platform on the truss, and pre-press the installed hanging basket platform before pouring concrete. After the pre-pressing is completed, the new section of the bridge is poured. After solidification, the truss is driven to slide on the track to drive the hanging basket platform forward a certain distance, so as to facilitate the pouring of the next section of the bridge.
[0004] Traditional hanging basket preloading adopts the stacking preloading method, which is to stack standard weight blocks (water bags, sand bags, concrete blocks, etc.) in batches according to 50%-100%-120% of the preloading weight on the hanging basket platform through a crane. After the preloading is completed, the standard weight blocks need to be lifted off the hanging basket again.
[0005] When there is a river or a reliable water source at the bridge construction site, water bag pre-loading is usually used for pre-loading. Specifically, the water bag is fixed on the hanging basket platform, and then water is pumped into the water bag through a pump. The amount of water pumped into the water bag is controlled to perform pre-loading in batches according to 50%-100%-120% of the pre-loading weight. After the pre-loading is completed, the water in the water bag is discharged to complete the pre-loading of the hanging basket platform. However, since the water bag is made of relatively soft waterproof fabric and the height of the hanging basket platform is relatively high, when the hanging basket shakes, the accumulated water in the water bag shakes with it, and it takes a long time to be completely stable. At the same time, since the capacity of the water bag is fixed, the accumulated water in the water bag is more likely to shake when the water bag is not full, thereby reducing the accuracy of the water bag's pre-loading of the hanging basket. Summary of the invention
[0006] In order to improve the efficiency and accuracy of basket loading preloading, the present application provides a double-line continuous beam basket.
[0007] The present application provides a double-line continuous beam hanging basket, which adopts the following technical solution: A double-track continuous beam hanging basket comprises a hanging basket mechanism arranged at both ends of a bridge, the hanging basket mechanism comprises a sliding track, a truss and a hanging basket platform, the sliding track is arranged on the bridge, the truss is slidingly arranged on the sliding track, the hanging basket platform is installed on the truss by a steel cable suspension connection, and a plurality of pre-pressing mechanisms for pre-pressing the hanging basket mechanism are detachably arranged on the hanging basket platform, and the pre-pressing mechanism comprises: A pre-pressing box, which is detachably mounted on the hanging basket platform, and in which a certain amount of accumulated water can be contained and used to pre-press the hanging basket platform; A box cover, which is slidably arranged on the pre-pressing box and pressed against the top of the accumulated water inside the pre-pressing box; An exhaust assembly, which is arranged on the box cover and is used to exhaust the air between the pre-compression box and the box cover; A driving assembly is arranged on the pre-pressing box and is used to control the maximum space between the box cover and the pre-pressing box.
[0008] By adopting the above technical scheme, the pre-compression box is placed on the hanging basket platform, the maximum space between the box cover and the pre-compression box is limited by the driving component, and then water is poured into the pre-compression box by an external water pump. The box cover is pushed to slide upward and finally pressed against the limit block by the water pressure and the buoyancy of the box cover, and the air between the pre-compression box and the box cover is discharged by the exhaust component, thereby reducing the probability of water shaking in the pre-compression box. The maximum space between the pre-compression box and the box cover is controlled by the driving component, thereby controlling the water volume inside the pre-compression box, and pre-compression is performed in batches according to 50%-100%-120% of the pre-compression weight. After the pre-compression is completed, the water in the pre-compression box is discharged, so as to complete the pre-compression of the hanging basket platform and improve the efficiency and accuracy of the hanging basket loading pre-compression.
[0009] Further, the exhaust assembly comprises: A connecting pipe, which is arranged on the box cover and communicates with the interior of the space between the pre-pressing box and the box cover; An exhaust pipe, wherein the exhaust pipe is sealed and arranged on the connecting pipe, the exhaust pipe is tapered inside and the diameter of the end close to the connecting pipe is larger than the diameter of the end far from the connecting pipe; A sealing ball is arranged in the connecting pipe through an elastic rope with a certain elastic force and is used to seal the exhaust pipe. The sealing ball can float on the water surface. When there is no water accumulation in the connecting pipe, the sealing ball moves away from the exhaust pipe under the action of gravity. The diameter of the sealing ball is smaller than the inner diameter of the connecting pipe.
[0010] By adopting the above technical solution, when there is no water in the connecting pipe, the sealing ball moves away from the exhaust pipe under the action of gravity, which facilitates the passage of gas. When the amount of water in the connecting pipe increases, the sealing ball presses against the inner wall of the exhaust pipe under the action of buoyancy, thereby preventing the water in the exhaust pipe from being discharged, thereby reducing the amount of air between the pre-compression box and the box cover.
[0011] Furthermore, the exhaust components are provided in multiple groups, and the multiple groups of the exhaust components are located at the corners of the box cover close to the side wall of the pre-pressing box.
[0012] By adopting the above technical solution, multiple groups of exhaust pipes are installed on the corners of the box cover, thereby reducing the amount of air between the pre-compression box and the box cover.
[0013] Furthermore, the pre-pressing box is provided with a water inlet valve for injecting water into the space between the pre-pressing box and the box cover, and the pre-pressing box is provided with a control component for controlling the start and stop of the water inlet valve, and the control component includes: A sensor, the sensor is arranged in the connecting pipe and is used to detect the hydraulic pressure value in the connecting pipe, and the sensor is arranged in multiple groups and is respectively located in multiple groups of connecting pipes; A controller is electrically connected to the plurality of sensor groups and is used to control the opening or closing of the water inlet valve.
[0014] By adopting the above technical solution, when the hydraulic values of multiple groups of sensors reach the set hydraulic values, the controller closes the water inlet valve to prevent the water from continuing to be discharged into the pre-pressurization box through the external drain pipe, thereby ultimately achieving control of the amount of water accumulated in the pre-pressurization box.
[0015] Further, the pre-press box is provided with a plurality of drive components, and the plurality of drive components are arranged at the diagonal positions of the pre-press box, and the drive components include: A limit block, which slides vertically along the inner wall of the pre-pressing box and limits the upward movement of the box cover; An electric telescopic rod is arranged on the pre-pressing box and is used to drive the limit block to slide.
[0016] By adopting the above technical solution, the electric telescopic rod drives the limit block to slide on the inner wall of the pre-press box, and the limit block is used to limit and tighten the bottom top of the box cover, thereby controlling the maximum space between the pre-press box and the box cover.
[0017] Furthermore, the box cover is provided with a plurality of side panels, which are perpendicular to the box cover and slidably abut against the inner side wall of the pre-pressing box.
[0018] By adopting the above technical solution, when the box cover slides on the inner wall of the pre-pressing box, the multiple groups of side panels and the inner wall of the pre-pressing box slide and press against each other, thereby reducing the probability of the box cover tipping over and deviating.
[0019] Furthermore, a soft bag for holding water is provided in the pre-compression box, the top of the soft bag is locked with the box cover and the bottom of the soft bag is locked on the bottom of the pre-compression box, the internal space of the soft bag is the same as the maximum volume between the pre-compression box and the box cover, and the connecting pipe passes through the soft bag and is connected with the inside of the soft bag.
[0020] By adopting the above technical solution, the water discharged into the pre-compression box is contained in the soft bag, so that the box cover only supports the top of the soft bag, thereby reducing the waterproof sealing requirements at the connection between the pre-compression box and the box cover, and also reducing the probability of water accumulation in the pre-compression box penetrating due to excessive pressure.
[0021] Furthermore, a support seat is provided at the bottom of the pre-pressing box, and the support seat is arranged on the hanging basket platform, and the support seat is kept horizontal close to the end surface of the pre-pressing box.
[0022] By adopting the above technical solution, the pre-pressing box is fixedly installed on the inclined hanging basket platform through the support seat. The pre-pressing box is kept horizontal through the support of the support seat, thereby reducing the probability of uneven force at the same height inside the pre-pressing box.
[0023] Furthermore, a plurality of groups of protrusions are arranged at the bottom of the box cover, and the protrusions are immersed in the water inside the pre-press box. The protrusions are hollow inside and are used to provide buoyancy to the box cover.
[0024] By adopting the above technical solution, when the protrusion is completely immersed in the water inside the pre-press box, the buoyancy generated can push the box cover to float on the water surface, thereby reducing the hydraulic value inside the pre-press box, making it easier to drive the box cover to rise with the water surface.
[0025] Furthermore, a filter net is arranged in the connecting pipe. When there is no water accumulation in the connecting pipe, the sealing ball falls onto the filter net under the action of gravity. The filter net is used to prevent larger impurities in the connecting pipe from entering the exhaust pipe.
[0026] By adopting the above technical solution, it is convenient to support the sealing ball when there is no water in the connecting pipe. When there is water in the connecting pipe, the larger impurities in the water are filtered to reduce the content of impurities in the exhaust pipe, thereby ensuring the good sealing performance of the sealing ball on the exhaust pipe.
[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. The pre-compression box is placed on the hanging basket platform, the limit block is driven to the specified position by the electric telescopic rod, and then water is poured into the pre-compression box by the external water pump. The box cover is pushed upward and finally pressed against the limit block by the water pressure and the buoyancy of the box cover. At the same time, the exhaust pipe and the sealing ball cooperate with each other to discharge the air between the pre-compression box and the box cover, thereby reducing the probability of water shaking in the pre-compression box. The position of the limit block is controlled by the electric telescopic rod, and the water volume inside the pre-compression box is controlled, and then pre-compression is performed in batches according to 50%-100%-120% of the pre-compression weight. After the pre-compression is completed, the water in the pre-compression box is discharged through the water inlet valve to complete the pre-compression of the hanging basket platform and improve the efficiency and accuracy of the hanging basket heap pre-compression.
[0028] 2. The water discharged into the pre-compression box is contained in a soft bag, so that the box cover only supports the top of the soft bag, thereby reducing the waterproof sealing requirements at the connection between the pre-compression box and the box cover, and also reducing the probability of water infiltration in the pre-compression box due to excessive pressure.
[0029] 3. The pre-compression box is fixedly installed on the inclined hanging basket platform through a support seat. The support of the support seat keeps the pre-compression box level, thereby reducing the probability of uneven force at the same height inside the pre-compression box.

[0036] Reference Figure 1 and Figure 2 When the truss 11 and the hanging basket platform 12 are installed, a counterweight is fixed on the truss 11 to fix the truss 11 on the zero bridge. Before pouring the bridge, multiple sets of pre-stressing mechanisms 2 are hoisted onto the hanging basket platform 12 by a crane, and multiple sets of pre-stressing mechanisms 2 are fixedly installed on the hanging basket platform 12 at intervals, so as to facilitate the subsequent pre-stressing of the hanging basket platform 12; two sets of pre-stressing mechanisms 2 are arranged on one set of hanging basket platforms 12 in this embodiment.
[0037] Reference Figure 2 and Figure 3 The prestressing mechanism 2 includes a prestressing box 21, a box cover 22 and an exhaust assembly 3. The bottom of the prestressing box 21 is fixedly installed on the upper surface of the hanging basket platform 12 by bolts. The interior of the prestressing box 21 is hollow and the top is open. A certain amount of accumulated water can be contained in the prestressing box 21. The hanging basket platform 12 is prestressed by the weight of the accumulated water and the prestressing box 21 itself; the box cover 22 is slidably installed in the prestressing box 21, and the box cover 22 seals the top of the prestressing box 21. The box cover 22 is pressed against the top of the accumulated water in the prestressing box 21. The box cover 22 is pressed against the accumulated water in the prestressing box 21, thereby reducing the probability of the accumulated water in the prestressing box 21 shaking.
[0038] Reference Figure 3 and Figure 4The exhaust assembly 3 is arranged on the box cover 22, and the exhaust assembly 3 is used to exhaust the air between the pre-pressing box 21 and the box cover 22. The exhaust assembly 3 includes a connecting pipe 31, an exhaust pipe 32 and a sealing ball 33. The connecting pipe 31 is fixedly installed on the box cover 22, and the connecting pipe 31 is connected to the space between the pre-pressing box 21 and the box cover 22, so as to facilitate the gas and liquid between the pre-pressing box 21 and the box cover 22 to be discharged through the connecting pipe 31; the exhaust pipe 32 is sealed and installed on the end of the connecting pipe 31 away from the box cover 22, and the interior of the exhaust pipe 32 is a conical structure, and the diameter of the exhaust pipe 32 near the end of the connecting pipe 31 is larger than the diameter of the end away from the connecting pipe 31; the sealing ball 33 is fixedly installed inside the connecting pipe 31 by an elastic rope with a certain elastic force, and the sealing ball 33 is used to block the exhaust pipe 32, and the sealing ball 33 can float on the water surface, and the diameter of the sealing ball 33 is smaller than the inner diameter of the connecting pipe 31, and the diameter of the sealing ball 33 is larger than the smallest inner diameter in the exhaust pipe 32.
[0039] Reference Figure 3 and Figure 4 A filter screen 34 is fixedly installed inside the connecting pipe 31, and the sealing ball 33 is located on the filter screen 34. The other end of the elastic rope is fixedly installed on the filter screen 34. When there is no water accumulation in the connecting pipe 31, the sealing ball 33 falls on the filter screen 34 under the action of gravity, so that the sealing ball 33 is away from the exhaust pipe 32, so as to facilitate the discharge of excess gas in the connecting pipe 31 through the exhaust pipe 32; when the water accumulation in the connecting pipe 31 increases, the filter screen 34 blocks the larger impurities in the accumulated water, and reduces the probability of the impurities entering the exhaust pipe 32. The sealing ball 33 moves toward the exhaust pipe 32 under the action of buoyancy and stretches the elastic rope. When the sealing ball 33 is pressed against the inside of the exhaust pipe 32, the sealing ball 33 seals the exhaust pipe 32, so as to prevent the accumulated water in the connecting pipe 31 from being discharged through the exhaust pipe 32.
[0040] Reference Figure 2 and Figure 3 , multiple groups of exhaust components 3 are provided, and the multiple groups of exhaust components 3 are located at the corners of the box cover 22 close to the side wall of the pre-pressing box 21; in this embodiment, two groups of exhaust components 3 are provided, and the two groups of exhaust components 3 are respectively located at the opposite diagonal positions of the box cover 22, so as to ensure that the air between the pre-pressing box 21 and the box cover 22 is completely discharged.
[0041] Reference Figure 2 and Figure 3The prepressing mechanism 2 also includes a driving assembly 4, which is arranged on the prepressing box 21 and is used to control the maximum space between the box cover 22 and the prepressing box 21. The prepressing box 21 is provided with multiple sets of driving assemblies 4, which are respectively located at the diagonals of the prepressing box 21. The driving assembly 4 includes a limit block 41 and an electric telescopic rod 42. The limit block 41 slides vertically along the inner wall of the prepressing box 21. The limit block 41 limits the upward movement of the box cover 22. When the upper surface of the box cover 22 is pressed against the lower surface of the limit block 41, the limit block 41 prevents the box cover 22 from moving away from the prepressing box 21. The pre-pressing box 21 slides in the bottom direction to control the maximum space between the pre-pressing box 21 and the box cover 22; the electric telescopic rod 42 is fixedly installed on the pre-pressing box 21, and the movable end of the electric telescopic rod 42 is fixedly connected to the limit block 41, and the electric telescopic rod 42 is used to drive the limit block 41 to slide on the pre-pressing box 21; two groups of driving components 4 are provided on the pre-pressing box 21 of this embodiment, and the limit block 41 is an L-shaped structure. The movable end of the electric telescopic rod 42 is fixedly installed at the corner of the L-shaped limit block 41, so as to improve the limit block 41 The tight limiting effect of the box cover 22.
[0042] Reference Figure 2 and Figure 4 The pre-pressurization box 21 is provided with a water inlet valve for injecting water into the space between the pre-pressurization box 21 and the box cover 22. The pre-pressurization box 21 is provided with a control component for controlling the start and stop of the water inlet valve. The control component includes a sensor and a controller. The sensor is fixedly installed in the connecting pipe 31. The sensor is used to detect the hydraulic pressure value in the connecting pipe 31. There are multiple groups of sensors, and the multiple groups of sensors are respectively located in the multiple groups of connecting pipes 31; the controller is fixedly installed on the outside of the pre-pressurization box 21, and the controller is electrically connected to the multiple groups of sensors in the same pre-pressurization box 21. The controller is used to control the opening or closing of the water inlet valve; specifically, when the hydraulic pressure values in the multiple groups of sensors are not fully When the hydraulic pressure reaches the set value, the controller keeps the water inlet valve open to facilitate the external drain pipe to drain water into the pre-compression box 21, and the accumulated water pushes the box cover 22 to slide in the pre-compression box 21. When the box cover 22 is pressed against the limit block 41, the limit block 41 prevents the box cover 22 from continuing to move up, and the air in the pre-compression box 21 and the box cover 22 is discharged through the exhaust pipe 32. When the hydraulic values of multiple groups of sensors reach the set hydraulic values, the controller closes the water inlet valve to prevent the external drain pipe from continuing to drain water into the pre-compression box 21, thereby finally controlling the amount of water accumulated in the pre-compression box 21, and then controlling the pre-compression weight of the hanging basket platform 12.
[0043] Reference Figure 2 and Figure 3In order to reduce the probability of the box cover 22 tipping over and deviating when the box cover 22 slides, multiple sets of side plates 221 are fixedly installed on the upper surface of the box cover 22. The multiple sets of side plates 221 are perpendicular to the box cover 22 and slide against the inner wall of the pre-pressing box 21. When the box cover 22 slides on the inner wall of the pre-pressing box 21, the multiple sets of side plates 221 and the inner wall of the pre-pressing box 21 slide and press against each other, thereby reducing the probability of the box cover 22 tipping over and deviating. The multiple sets of side plates 221 of this embodiment are connected end to end to form a rectangular ring structure.
[0044] Reference Figure 2 and Figure 3 A plurality of lifting ears are fixedly installed on the side wall of the pre-compression box 21, and the plurality of lifting ears facilitate the crane to drive the pre-compression box 21 to move when lifting the pre-compression box 21; a plurality of protrusions 222 are fixedly installed on the bottom of the box cover 22, and the plurality of protrusions 222 are immersed in the water inside the pre-compression box 21. The protrusions 222 are hollow inside and are used to provide a large buoyancy for the box cover 22, so as to facilitate the water in the pre-compression box 21 to drive the box cover 22 to move upward; the buoyancy generated when the protrusions 222 of this embodiment are completely immersed in water is just equal to the dead weight of the box cover 22.
[0045] Reference Figure 1-Figure 4 The specific operation process is to fix the truss 11 on the sliding track 1, and then fix the hanging basket platform 12 on the truss 11, fix the truss 11, and then the crane lifts the pre-compression box 21 to the hanging basket platform 12 through the lifting ear, and then fix the pre-compression box 21, and then the electric telescopic rod 42 drives the limit block 41 to move to the specified position away from the bottom of the pre-compression box 21, and fix the external drain pipe on the water inlet valve, and then the external water pump discharges water into the space between the pre-compression box 21 and the box cover 22. As the water level in the pre-compression box 21 gradually rises, the box cover 22 is driven to slide upward under the action of water pressure and buoyancy, and at the same time, the gas between the pre-compression box 21 and the box cover 22 is discharged through the exhaust pipe 32. When the box cover 22 is pressed against the limit block 41, the limit block 4 1 prevents the box cover 22 from sliding, and the water in the pre-compression box 21 enters the connecting pipe 31, thereby driving the sealing ball 33 to seal the exhaust pipe 32, and the liquid pressure in the connecting pipe 31 gradually increases. When the multiple sets of sensors reach the set hydraulic value, the water inlet valve is closed by the controller, and the external water pump is also closed, so as to achieve the filling of a specified volume of water into the pre-compression box 21; when the first pre-compression is completed, the electric telescopic rod 42 drives the limit block 41 to move upward, and the box cover 22 continues to move upward under the action of water pressure, and then the water pump is started again to fill the accumulated water into the pre-compression box 21, so as to perform pre-compression in batches according to 50%-100%-120% of the pre-compression weight. After the pre-compression is completed, the water in the pre-compression box 21 is discharged through the water inlet valve, so as to complete the pre-compression of the hanging basket platform 12.
[0046] Reference Figure 1 and Figure 2In order to improve the stability of continuous bridge construction, a double-line construction method is adopted. Specifically, with Bridge No. 0 as the symmetry axis, construction is carried out on both sides of Bridge No. 0 at the same time. After the pre-stress boxes 21 on the hanging basket platforms 12 on both sides of Bridge No. 0 are installed, water is pumped into the pre-stress boxes 21. By real-time monitoring of the distance between the box cover 22 of the pre-stress boxes 21 on both sides and the bottom of the pre-stress boxes 21, it is convenient to ensure that the pre-stress weight on both sides is always kept equal.
[0047] The working principle of Example 1 of the present application is: The pre-stress box 21 is placed on the hanging basket platform 12, and the limit block 41 is driven to the specified position by the electric telescopic rod 42, and then water is poured into the pre-stress box 21 by an external water pump. The box cover 22 is pushed to slide upward and finally pressed against the limit block 41 by the water pressure and the buoyancy of the box cover 22. At the same time, the exhaust pipe 32 and the sealing ball 33 cooperate with each other to discharge the air between the pre-stress box 21 and the box cover 22, thereby reducing the probability of water shaking in the pre-stress box 21. The position of the limit block 41 is controlled by the electric telescopic rod 42, and the water amount in the pre-stress box 21 is controlled, and then pre-stressing is performed in batches according to 50%-100%-120% of the pre-stressing weight. After the pre-stressing is completed, the water in the pre-stress box 21 is discharged through the water inlet valve, so as to complete the pre-stressing of the hanging basket platform 12 and improve the efficiency and accuracy of the hanging basket loading pre-stressing.
[0048] Example 2 Reference Figure 5 The difference between this embodiment and embodiment 1 is that a soft bag 5 for holding water is provided in the hydraulic box, the bottom of the soft bag 5 is fixedly mounted on the bottom of the pre-compression box 21, and the top of the soft bag 5 is fixedly mounted on the lower surface of the box cover 22. The internal space of the soft bag 5 is the same as the maximum volume between the pre-compression box 21 and the box cover 22, so that when the soft bag 5 is filled with water, it is pressed against the side wall of the pre-compression box 21, thereby reducing the waterproof sealing requirement at the connection between the box cover 22 and the pre-compression box 21; at the same time, the connecting pipe 31 passes through the soft bag 5 and is connected to the inside of the soft bag 5, so as to facilitate the discharge of air in the soft bag 5; the soft bag 5 of this embodiment has a certain elasticity, so as to facilitate better fitting on the side wall of the pre-compression box 21; at the same time, the water is contained by the soft bag 5, which reduces the probability of water corroding the pre-compression box 21.
[0049] The working principle of Example 2 of the present application is: The water discharged into the pre-compression box 21 is contained in the soft bag 5, so that the box cover 22 only supports the top of the soft bag 5, thereby reducing the waterproof sealing requirements at the connection between the pre-compression box 21 and the box cover 22, and also reducing the probability of water accumulation in the pre-compression box 21 penetrating due to excessive pressure.
[0050] Example 3 Reference Figure 6The difference between this embodiment and embodiment 1 is that, since the hanging basket platform 12 has a certain inclination, a support seat 6 is fixedly installed at the bottom of the pre-compression box 21, and the support seat 6 is fixedly installed on the hanging basket platform 12. The bottom of the support seat 6 abuts against the hanging basket platform 12 with an inclination, and the top of the support seat 6 remains horizontal. The bottom of the pre-compression box 21 is fixedly installed on the top of the support seat 6.
