Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, in particular to a construction method of a double diamond tower column. Background Art

[0002] The double diamond tower is a specially designed structure that can be used in large-span bridge projects. Its shape presents two interconnected diamonds to form a stable column structure. This design can provide good wind and earthquake resistance, and can also effectively disperse the load. Its shape is as follows: Figure 1 As shown, it generally includes an upper tower column 11, a cross beam 12 and a lower tower column 13. During the construction of the double diamond tower column, since the angle between the axis of the upper tower column 11 and the lower tower column 13 and the longitudinal line is relatively large, the construction process of the lower tower column 13 is similar to the construction process of the cantilever beam 2, as shown in FIG. Figure 2 As shown, it can be seen that the stress form of the lower tower column 13 is very similar to that of the cantilever beam 2, that is, it is easy to deform under the action of its own weight, so temporary support force needs to be applied during the construction process.

[0003] There are many ways to apply temporary support force during the construction of the double diamond tower column. For example, an adjustable inclined tower column construction support provided by the patent with publication number CN215925688U can be used for temporary support, which includes a steel pipe pile support, and a plurality of diagonal support supports are arranged above the steel pipe pile support. Each diagonal support support includes a horizontal support rod and a diagonal support rod. One end of the horizontal support rod is welded to the lower end of the diagonal support rod, and the other end and the upper end of the diagonal support rod are respectively welded to the embedded parts on the tower column. At least two load-bearing beams are arranged on the top of the steel pipe pile support in the transverse direction of the bridge. At least two distribution beams are set up along the bridge direction on the load-bearing beam. A jack is arranged on each distribution beam. A shoulder beam is set up on the upper transverse direction of each jack. The horizontal support rod of each diagonal support support is supported on the shoulder beam. The above-mentioned construction support can provide temporary support for the tower column, and when the tower column load causes the support to deform and the inclination angle of the tower column exceeds the design requirements, the diagonal support support can be pushed upward by the jack to adjust the tower column angle to meet the requirements.

[0004] In the above-mentioned prior art, in order to reduce the upper load of the jack, a cushion beam is provided on both sides of the jack, the bottom surface of the cushion beam is supported on the distribution beam, and a pad is provided between the top surface of the cushion beam and the bottom surface of the shoulder beam. After the jack is pushed, the pad is inserted between the cushion beam and the shoulder beam, so that the cushion beam and the pad can bear the upper load together with the jack, thereby reducing the upper load of the jack. However, the above-mentioned construction method has the following shortcomings in reducing the upper load of the jack: first, the staff needs to manually embed the pad at the high altitude position of the bracket, which has great operating difficulty and high operating risk; second, the height of each upward push of the jack is not consistent, but the pad is often of standard specifications, so it is easy to cause the thickness of the pad to be difficult to perfectly adapt to the pushing height of the jack, which ultimately makes it difficult for the pad and the cushion beam to fully play their effect of sharing the upper load of the jack. Summary of the invention

[0005] In order to solve the problems existing in the prior art, the present application provides a double diamond tower column construction method.

[0006] The invention provides a double diamond tower column construction method using the following technical solutions:

DETAILED DESCRIPTION

[0036] The following will be combined with the attached Figure 3 -Attached Figure 7 The present invention is further illustrated by the following embodiments.

[0037] Embodiment 1

[0038] This embodiment discloses a construction method for a double diamond tower column.

[0039] Reference Figure 3 The double diamond tower column construction method includes the following steps:

[0040] Preparation stage:

[0041] S1: First, a clamping plate 34 is arranged between the jack 31 and the shoulder pole beam 32, and then two push rods 35 are arranged at the bottom of the clamping plate 34, which are respectively located at the left and right sides of the jack 31, and then a sleeve 36 is threadedly connected to the lower end of the push rod 35;

[0042] S2: two sets of driving members are arranged in the distribution beam 33, and the two sets of driving members are respectively located below the two sleeves 36;

[0043] S3: Connecting a retractable transmission rod 4 between the sleeve 36 and the driving member;

[0044] Support phase:

[0045] S1: Using the construction support to provide temporary support for the lower tower column 13;

[0046] S2: When the construction support is deformed due to the load of the lower tower column 13, the jack 31 of the construction support is used to push the diagonal support to adjust the angle of the lower tower column 13;

[0047] S3: The sleeve 36 is driven to rotate downward by a driving member until the lower end of the sleeve 36 abuts against the top of the distribution beam 33 .

[0048] Through the above steps, on the one hand, the distance between the push rod 35 and the sleeve 36 can be quickly extended by using the driving member to drive the sleeve 36 to rotate downward, so as to quickly adapt to the support height after the jack 31 is pushed, reduce the difficulty of operation, and avoid operation risks; on the other hand, the process of the sleeve 36 rotating downward to extend the distance between the push rod 35 and the sleeve 36 is steplessly adjusted, that is, no matter how high the jack 31 pushes upward, the sleeve 36 can flexibly adapt, so as to give full play to its effect of sharing the upper load of the jack 31. In addition, the thread between the push rod 35 and the sleeve 36 has a self-locking effect, so as to achieve rapid locking after adjustment.

[0049] Reference Figures 3 to 5 In the preparation stage S1, the outer wall of the lower end of the push rod 35 is pre-opened with an external thread, the sleeve 36 is hollow inside and open at the upper end, and the inner wall of the sleeve 36 is pre-opened with an internal thread, and the upper end of the sleeve 36 is threadedly connected with the external thread of the lower end of the push rod 35 through the internal thread. In the preparation stage S1, the initial state of the jack 31 is its lowest pushing height, ensuring that the jack 31 has a sufficient pushing range in the subsequent use process. In addition, after the sleeve 36 is threadedly connected with the push rod 35, the upper end of the sleeve 36 must be at least located in the upper half of the push rod 35, ensuring that the sleeve 36 has a sufficient extension range in the subsequent use process, so that the jack 31 can still share the upper load for the jack 31 after the jack 31 is pushed.

[0050] Reference Figures 3 to 5 In the preparation stage S2, the driving member is a motor 51, and the power output shaft of the motor 51 is vertically upward. In order to facilitate the installation of the motor 51, an installation cavity is reserved from the outer wall to the inside of the distribution beam 33, and the motor 51 is installed in the installation cavity of the distribution beam 33.

[0051] Reference Figures 3 to 5In S3 of the preparation stage, the transmission rod 4 includes an upper connecting rod 41 and a lower connecting rod 42, wherein the upper end of the upper connecting rod 41 is fixedly connected to the lower end of the sleeve 36, the upper connecting rod 41 is coaxially connected to the sleeve 36, the lower end of the lower connecting rod 42 is fixedly connected to the upper end of the power output shaft of the motor 51, the lower connecting rod 42 is coaxial with the power output shaft of the motor 51, and the lower end of the upper connecting rod 41 is axially provided with a plug hole, the plug hole is a rectangular hole, the upper end of the lower connecting rod 42 is axially provided with a plug rod, the plug rod is a rectangular rod, the plug rod of the lower connecting rod 42 is plugged into the plug hole of the upper connecting rod 41, so that the motor 51 can drive the sleeve 36 to rotate through the lower connecting rod 42 and the upper connecting rod 41 in turn, thereby realizing the transmission function of the transmission rod 4, and also making the upper connecting rod 41 and the lower connecting rod 42 relatively telescopic, thereby realizing the telescopic function of the transmission rod 4. In order to facilitate the installation of the transmission rod 4, a mounting hole is reserved at the top of the distribution beam 33, and the transmission rod 4 is installed in the mounting hole.

[0052] Reference Figures 3 to 5 In the supporting stage, as the jack 31 pushes, the sleeve 36 needs to rotate downward and extend, which will gradually increase the distance between the lower end of the push rod 35 and the lower end of the sleeve 36, resulting in a larger hollow range inside the sleeve 36, thereby increasing the risk of the lower end of the sleeve 36 deforming inward at the hollow, which may eventually affect the supporting effect of the sleeve 36. To this end, in S2 of the preparation stage, two gear pumps 52 are arranged in the distribution beam 33, and the two gear pumps 52 are respectively located below the two sleeves 36. The suction chamber of the gear pump 52 is connected to the water source 71, and the discharge chamber of the gear pump 52 is connected to the cavity of the sleeve 36. The end of the pipe 53 away from the gear pump 52 is connected to the cavity of the sleeve 36 after passing through the push rod 35. Further, the power input shaft of the gear pump 52 is connected to the power output shaft of the motor 51. Through the above-mentioned improvements, in the supporting stage, when the motor 51 controls the sleeve 36 to rotate and extend downward, the motor 51 simultaneously controls the gear pump 52 to pump water into the cavity of the sleeve 36, so as to ensure that the cavity of the sleeve 36 is always filled with water, thereby reducing the risk of the lower end of the sleeve 36 deforming inward at the hollow part, thereby avoiding affecting the supporting effect of the sleeve 36.

[0053] Reference Figures 3 to 5In the preparation stage, a pressure sensor 72 is also provided at the bottom of the sleeve 36, and the pressure sensor 72 is connected to the motor 51 signal. When the motor 51 controls the sleeve 36 to rotate downward, when the bottom of the sleeve 36 contacts the distribution beam 33 and the pressure sensed by the pressure sensor 72 exceeds the pressure threshold, the motor 51 stops, so that the sleeve 36 stops rotating and the gear pump 52 stops pumping water, thereby realizing automatic control. In addition, a one-way valve 54 is provided at the connection between the pipe 53 and the cavity of the sleeve 36. The one-way valve 54 is provided to prevent the water in the cavity of the sleeve 36 from flowing back, so as to prevent the anti-deformation pressure of the sleeve 36 from being transferred to the pipe 53 and the gear pump 52 through the water pressure when the sleeve 36 is supported, thereby protecting the pipe 53 and the gear pump 52. The cavity of the sleeve 36 is also connected to a drain port 73, and the drain port 73 is provided with a drain switch, so as to drain the water in the sleeve 36 when necessary.

[0054] Reference Figures 3 to 5 Although the threaded connection between the sleeve 36 and the push rod 35 can provide a certain sealing effect, liquid may still penetrate into the tiny gaps between the threads. For this reason, in the preparation stage S1, a sealing tape such as polytetrafluoroethylene tape (PTFE tape) is wound on the external thread at the lower end of the push rod 35. When the sleeve 36 is threadedly connected to the push rod 35, the sealing tape can effectively fill the gaps between the threads and provide an additional sealing effect.

[0055] Embodiment 2

[0056] This embodiment discloses a construction method for a double diamond tower column.

[0057] Reference Figure 3 , Figure 6 and Figure 7, The difference from the first embodiment is that: in the preparation stage S2, the driving part is a turbine 61, the turbine 61 includes a water inlet end, a water outlet end and a power output shaft, the power output shaft of the turbine 61 is coaxially connected with the transmission rod 4, and the water inlet end and the water outlet end of the turbine 61 are connected to a water pump 62 and a water source 71 through a pipeline 53 to form a circulation pipeline. Further, the pipeline 53 includes a main pipe 63 and a branch pipe 64, the main pipe 63 is connected between the water outlet end of the turbine 61 and the water source 71, the branch pipe 64 is connected between the main pipe 63 and the cavity of the sleeve 36, and a switching valve 65 is provided at the connection between the main pipe 63 and the branch pipe 64. The bottom of the sleeve 36 is also provided with a pressure sensor 72, the pressure sensor 72 is connected to the switching valve 65 signal, and the pressure sensor 72 controls the switching valve 65 to switch when the sensed pressure exceeds the threshold. In addition, a water level sensor 66 is provided at the bottom of the push rod 35, and the water level sensor 66 is connected to the water pump 62 by signal. The water level sensor 66 controls the water pump 62 to shut down when the water level exceeds the threshold. Through the above arrangement, when the jack 31 is pushed upward, the water pump 62 is started and the switching valve 65 controls the front and rear sections of the main pipe 63 to be connected, and the water in the circulation pipeline continues to flow, so that the power output shaft of the turbine 61 continuously drives the transmission rod 4 to rotate, thereby driving the sleeve 36 to rotate downward, until the sleeve 36 rotates downward to the top of the distribution beam 33, at which time the pressure sensor 72 controls the switching valve 65 loop, so that the front section of the main pipe 63 is connected to the branch pipe 64, so that the water from the water source 71 is continuously added to the cavity of the sleeve 36, until the cavity in the sleeve 36 is full of water, at which time the water level sensor 66 controls the water pump 62 to shut down, and the adjustment is completed. In the first embodiment, the downward rotation of the sleeve 36 and the water replenishment of the sleeve 36 cavity are performed simultaneously, and the relationship between the stroke of the sleeve 36 and the amount of water replenished in the sleeve 36 needs to be accurately controlled to ensure that the sleeve 36 rotates downward to the right position and its cavity is also filled with water. In this embodiment, the process of the sleeve 36 rotating downward and the water replenishment in the sleeve 36 is performed in steps, and there is no need to consider the relationship between the stroke of the sleeve 36 and the amount of water replenished in the sleeve 36, which reduces the design difficulty.

[0058] The above are all preferred embodiments of the present invention, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
