Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, and in particular to a method for bridge closure construction. Background Technology

[0002] In bridge construction using integrated pile-beam erection machines, the process begins with driving piles (usually PHC high-strength concrete pipe piles) into the ground using the machine's piling system. Then, the bridge erection system (typically including main beams, legs, and overhead cranes) is used to construct cap beams, T-beams, or double T-beams on top of the piles. Pile and beam construction must be carried out alternately, and the integrated pile-beam erection machine must also pass through the bridge's spans to ensure sequential construction of each pile and beam segment along the bridge's length. However, current integrated pile-beam erection operations often use only one machine to construct in the same direction (from one end of the bridge to the other), which may not be suitable for all situations. For bridges with large spans, using only one integrated pile-beam machine can reduce construction efficiency and extend the construction period. Therefore, in some construction projects, two integrated pile-beam machines (such as Pile-Beam Machine No. 1 and Pile-Beam Machine No. 2) are used to work simultaneously from both ends of the bridge towards the middle, which can improve construction efficiency. However, for the construction of the closure section, if the two integrated pile-beam machines are directly connected using the existing closure method of ordinary bridge erecting machines, there is a risk that the pile driving systems of the two integrated pile-beam machines will interfere with each other, or that the pile driving system will interfere with the bridge piles on the travel route, thus affecting the safety of the operation. Therefore, for the construction of the closure section using integrated pile-beam machines, it is necessary to improve the existing closure method of ordinary bridge erecting machines to overcome the above problems. Summary of the Invention

[0003] The purpose of this invention is to overcome the technical problems existing in the prior art, where using a pile-beam integrated machine and following the method of ordinary bridge erection machine for closure and closure operations will cause the pile driving system to interfere with the operation and lead to operational safety hazards, and to provide a bridge closure construction method.

[0004] This invention provides a bridge closure construction method, employing a first integrated pile-beam machine and a second integrated pile-beam machine, wherein the piling systems of the first and second integrated pile-beam machines are arranged facing each other. The closure construction method includes:

[0005] S1: The first pile-beam integrated machine constructs to the first preset pile position along the first through-hole direction, and the second pile-beam integrated machine constructs to the second preset pile position along the second through-hole direction; the first through-hole direction and the second through-hole direction are opposite, and the closure section includes the area between the first preset pile position and the second preset pile position;

[0006] S2: Remove the pile hammer, pilot drill rod, pile frame bottom section and auxiliary legs of the first integrated pile and beam machine, or remove the pile hammer, pilot drill rod, pile frame bottom section and auxiliary legs of the second integrated pile and beam machine;

[0007] S3: The pile-beam integrated machine that has undergone the S2 removal step is moved backward along the corresponding through-hole direction until it is completely out of the closure section; the pile-beam integrated machine that has not undergone the S2 removal step completes the pile driving operation of the closure section along the corresponding through-hole direction, and the beam construction of the area covered by the corresponding pile-beam integrated machine in the closure section.

[0008] S4: Dismantle the pile hammer, borehole drill rod, pile frame bottom section and auxiliary legs of the pile-beam integrated machine used in S3 for the construction of the closure section;

[0009] S5: After the demolition step S4, the integrated pile-beam machine completes the construction of the remaining part of the beam body of the closure section described in S3 along the corresponding through-hole direction.

[0010] S6: After the removal step S4, the integrated pile and beam machine leaves the closure section along the first or second through-hole direction, completing the closure.

[0011] This invention employs two integrated pile-beam machines to construct the bridge from both ends towards the middle. The location and extent of the closure section can be predetermined. For example, the closure section includes at least the area between the first and second pre-set pile positions. The first and second pre-set pile positions can be the locations of the last bridge piles constructed by the two integrated pile-beam machines at their closest points. The two integrated pile-beam machines can first construct to the first and second pre-set pile positions, completing the pile driving operation at these positions. To prevent the two integrated pile-beam machines from continuing to approach each other and interfering with the pile driving systems on both sides, some components of the pile driving system on one side of the integrated pile-beam machine can be removed, such as the pile hammer, the pilot drill rod, the bottom section of the pile frame (to avoid interference between the pile frame and bridge piles on the travel path), and auxiliary support legs. Then, the dismantled integrated machine is moved back to exit the closure section, leaving the closure section entirely for the other side. The integrated machine on one side can carry out subsequent construction, while the integrated machine on the other side can enter the closure section along the original through-hole direction to carry out pile driving and beam construction in sequence. After the bridge piles of the last span in the closure section are completed, the components of the pile driving system on the integrated machine on the other side can be removed. After removal, the integrated machine can continue to pass through the hole and complete the beam construction of the remaining part of the closure section (i.e., the bridge piles for which the beam has not yet been constructed). At this point, the construction of the closure section is completed. Then, the integrated machine can be withdrawn forward or backward from the closure section to complete the overall closure of the bridge. The closure method adopted in this invention can promptly remove the pile driving system and auxiliary legs that may cause interference after the integrated pile and beam machines on both sides have completed their respective pile driving operations, and control one integrated machine to retreat to make room for the closure section so that the other integrated machine can complete the construction of the closure section. This can ensure work efficiency while avoiding the risk of interference from components such as the pile driving system, thus improving work safety.

[0012] Preferably, in S2, if the pile hammer, pilot drill rod, pile frame bottom section and auxiliary support legs of the second pile-beam integrated machine are removed, and the closure section includes a third preset pile position, then in S3, the first pile-beam integrated machine is used to complete the pile driving operation of the third preset pile position along the first through hole direction, and the first pile-beam integrated machine is used to complete the beam construction between the first preset pile position and the third preset pile position.

[0013] Preferably, in step S4, the pile hammer, pilot drill rod, pile frame bottom section, and auxiliary support legs of the first integrated pile and beam machine are removed.

[0014] Preferably, in S5, the first integrated pile-beam machine is used to complete the beam construction between the third preset pile position and the second preset pile position along the first through-hole direction.

[0015] After both integrated machines reach their respective preset pile positions, the piling system on one of the integrated machines can be removed. For example, the piling system of the second integrated pile and beam machine can be removed and moved outside the closure section, and the first integrated pile and beam machine can be used to continue to complete the pile driving and beam construction in the closure section.

[0016] Preferably, in S2, if the pile hammer, pilot drill rod, pile frame bottom section and auxiliary support legs of the first integrated pile and beam machine are removed, and the closure section includes a third preset pile position, then in S3, the second integrated pile and beam machine is used to complete the pile driving operation of the third preset pile position along the second through hole direction, and the second integrated pile and beam machine is used to complete the beam construction between the second preset pile position and the third preset pile position.

[0017] Preferably, in step S4, the pile hammer, pilot drill rod, pile frame bottom section, and auxiliary support legs of the second integrated pile and beam machine are removed.

[0018] Preferably, in S5, the second pile-beam integrated machine is used to complete the beam construction between the third preset pile position and the first preset pile position along the second through-hole direction.

[0019] Similarly, the piling system of the first integrated pile and beam machine can be dismantled and moved outside the closure section, and then the second integrated pile and beam machine can be used to continue the pile driving and beam construction in the closure section.

[0020] Preferably, S3 further includes: retracting the integrated pile-beam machine after the dismantling step S2 to a preset dismantling area, and dismantling the integrated pile-beam machine in the preset dismantling area using a crawler crane;

[0021] S6 also includes: moving the integrated pile-beam machine after the S4 dismantling step to the preset dismantling area, and dismantling the integrated pile-beam machine in the preset dismantling area by means of a crawler crane;

[0022] S2 also includes: using a crane on the dismantled pile-beam integrated machine to lift the dismantled components onto a vehicle, which is parked on the bridge and corresponds to the rear of the pile-beam integrated machine, and then using the vehicle to transfer the dismantled components.

[0023] Preferably, in S3 and S5, the beam construction includes:

[0024] C1: A cap beam is erected on top of the bridge piles formed by the pile driving operation;

[0025] C2: Install double T-beams between the bridge piles spaced along the direction of the through-hole, the double T-beams being erected on top of the cap beam.

[0026] Preferably, S2 further includes: using a crane on the integrated pile-beam machine after dismantling in S2 to transport the dismantled parts in S2 and place them on the constructed beam;

[0027] S4 also includes: using the overhead crane on the integrated pile-beam machine after dismantling in S4 to lift the components dismantled in S2 and S4 and place them on a vehicle, which is parked on the bridge and corresponds to the tail of the integrated pile-beam machine after dismantling in S4, and then using the vehicle to transfer the dismantled components.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] This invention provides a method for bridge closure construction. Two integrated pile-beam machines operate from both ends of the bridge towards the middle. The location and extent of the closure section can be predetermined. For example, the closure section includes at least the area between a first and a second pre-set pile position. The first and second pre-set pile positions can be the locations of the last bridge piles driven by the two integrated pile-beam machines at their closest points. The two integrated pile-beam machines can first drive to the first and second pre-set pile positions, completing the pile driving operation at these positions. To prevent the two integrated pile-beam machines from continuing to approach and interfering with the pile driving systems on both sides, some components of the pile driving system on one side of the integrated pile-beam machine can be removed, such as the pile hammer, the pre-drill rod for the pilot hole, the bottom section of the pile frame (to avoid interference between the pile frame and bridge piles on the travel path), and auxiliary legs. The dismantled integrated machine is then retreated to exit the closure section, completing the closure section. The entire space is reserved for the integrated machine on the other side to carry out subsequent construction. The integrated machine on the other side can enter the closure section along the original through-hole direction to carry out pile driving and beam construction in sequence. After the bridge piles of the last span in the closure section are completed, the pile driving system components on the integrated machine on the other side can be removed. After removal, the integrated machine can continue to move forward through the hole and complete the beam construction of the remaining part of the closure section (i.e., the bridge piles for which the beam has not yet been constructed). At this point, the construction of the closure section is completed. Then, the integrated machine can be moved forward or backward out of the closure section to complete the overall closure of the bridge. The closure method adopted in this invention can promptly remove the pile driving system and auxiliary legs that may cause interference after the integrated pile and beam machines on both sides have completed their respective pile driving operations. It can also control one integrated machine to retreat to make room for the closure section so that the other integrated machine can complete the construction of the closure section. This can ensure work efficiency while avoiding the risk of interference from components such as the pile driving system, thus improving work safety. Attached Figure Description

[0042] Example

[0043] This embodiment provides a method for bridge closure construction.

[0044] like Figures 1 to 4 As shown in the figure, the bridge closure construction method of this embodiment adopts a first pile-beam integrated machine 1 and a second pile-beam integrated machine 2. The piling system 3 of the first pile-beam integrated machine 1 and the piling system 3 of the second pile-beam integrated machine 2 are arranged facing each other. The closure construction method includes:

[0045] S1: The first pile-beam integrated machine 1 constructs along the first through-hole direction to the first preset pile position 4, and the second pile-beam integrated machine 2 constructs along the second through-hole direction to the second preset pile position 5; the first through-hole direction and the second through-hole direction are opposite, and the closure section 6 includes the area between the first preset pile position 4 and the second preset pile position 5;

[0046] S2: Remove the pile hammer, pilot drill rod, pile frame bottom section and auxiliary legs of the first integrated pile and beam machine 1, or remove the pile hammer, pilot drill rod, pile frame bottom section and auxiliary legs of the second integrated pile and beam machine 2;

[0047] S3: The pile-beam integrated machine that has undergone the S2 removal step is moved backward along the corresponding through-hole direction until it is completely removed from the closure section 6; the pile-beam integrated machine that has not undergone the S2 removal step completes the pile driving operation of the closure section 6 along the corresponding through-hole direction, and the beam construction of the area covered by the corresponding pile-beam integrated machine in the closure section 6.

[0048] S4: Remove the pile hammer, borehole drill rod, pile frame bottom section and auxiliary legs of the pile-beam integrated machine used for the construction of the closure section 6 in S3;

[0049] S5: After the demolition step S4, the integrated pile and beam machine completes the beam construction of the remaining part of the closure section 6 in S3 along the corresponding through-hole direction.

[0050] S6: After the removal step S4, the pile-beam integrated machine leaves the closure section 6 along the first or second through-hole direction, completing the closure.

[0051] Referring to the attached diagram, the first integrated pile and beam machine 1 is... Figure 1 , Figure 2 The second integrated pile-beam machine, located on the left, is the pile-beam integrated machine 2. Figure 1 , Figure 2 The integrated pile-beam machine located on the right side of the center has its first through-hole direction as... Figure 1 The direction from left to right, indicated by the middle arrow A, is the direction of the second via. Figure 1 The direction from right to left is indicated by the middle arrow B; Figures 1-4 Each pile location is marked with a corresponding number below it; the first preset pile location, 4, is... Figures 1-4 Pile No. 74 in the middle, the second preset pile position 5 is... Figures 1-4 Pile 76 is located in the closure section 6, which is the area between piles 74 and 76. In other words, closure section 6 covers piles 74, 75, and 76. Here, the beam structure located within the three spans on either side of closure section 6, specifically between piles 71 and 74, and between piles 76 and 79, is... Figure 1 and Figure 2 In this state, construction is temporarily impossible due to the outriggers occupying the space. It will also need to be constructed together with the closure section 6 as the integrated machine moves forward through the hole. Of course, the specific pile numbers corresponding to the first preset pile position 4 and the second preset pile position 5 can be selected according to the actual situation. The range of the closure section 6 also depends on the specific location of the first preset pile position 4 and the second preset pile position 5. The definition of the closure section 6 can also include the area between the first preset pile position 4 and the second preset pile position 5, as well as the areas on both sides of the first preset pile position 4 and the second preset pile position 5 where the beam cannot be constructed temporarily. The number of pile positions covered by the closure section 6 can also be selected, and is not limited to the situation shown in the attached figure.

[0052] Combined with appendix Figures 1 to 4 The specific process of the closure construction can be described:

[0053] like Figure 1 As shown, the first pile-beam integrated machine 1 and the second pile-beam integrated machine 2 firstly complete the pile driving and beam construction on both sides of the closure section 6. Specifically, the second pile-beam integrated machine 2 completes the pile driving, cap beam erection, and double T-beam installation at pile position 76, while the first pile-beam integrated machine 1 completes the pile driving, cap beam erection, and double T-beam installation at pile position 74. Then, the pile hammer, pilot drill rod, pile frame bottom section, and auxiliary support legs of the second pile-beam integrated machine 2 are removed, and the disassembled parts are transported to the warehouse for storage by the crane on the second pile-beam integrated machine 2.

[0054] like Figure 2As shown, after the second integrated pile-beam machine 2 removes the pile hammer and other devices, the entire machine retreats, sequentially transitioning the front outriggers from the top of the pile cap → the top of the cover beam → the top of the double T beam. Through the conventional hole-passing process, it retreats back to the dismantling area in the opposite direction of the second hole-passing direction, i.e., the direction of the first hole-passing direction, and is dismantled with the assistance of a crawler crane. After the first integrated pile-beam machine 1 completes all the work at pile position 74, it continues to move forward to complete all the work at pile position 75 in the closure section 6 (i.e., the driving of pile 75, and the beam construction between piles 74 and 75; here, the area between piles 74 and 75 is the area in the closure section 6 completely covered by the first integrated pile-beam machine 1). Then, the pile hammer, bolt drill, pile frame bottom section, and auxiliary outriggers of the first integrated pile-beam machine 1 are removed. The dismantled parts are transported to the warehouse for storage by the crane on the first integrated pile-beam machine 1.

[0055] like Figure 3 As shown, after the first pile-beam integrated machine 1 completes all the work at pile position 75 and dismantles and transports the pile hammer and other equipment, the first pile-beam integrated machine 1 continues to pass through the hole along the first through hole direction to complete the construction work of the remaining cap beam and double T beam (that is, the beam construction in the area between piles 75 and 76), and then completes the construction of closure section 6.

[0056] like Figure 4 As shown, after the completion of the closure section 6, the first pile-beam integrated machine 1 was moved to the dismantling area using the conventional hole-passing procedure, thus completing the overall construction operation of the bridge closure.

[0057] This invention employs two integrated pile-beam machines to construct the bridge from both ends towards the middle. The location and extent of the closure segment 6 can be predetermined. For example, the closure segment 6 includes at least the area between the first preset pile position 4 and the second preset pile position 5. The first preset pile position 4 and the second preset pile position 5 can be the location of the last bridge pile constructed by the two integrated pile-beam machines at their closest points. The two integrated pile-beam machines can first construct to the first preset pile position 4 and the second preset pile position 5, completing the pile driving operation at these positions. To prevent the two integrated pile-beam machines from continuing to approach and interfering with the pile driving systems 3 on both sides, some components of the pile driving system 3 on one side of the integrated pile-beam machine can be removed. These components include the pile hammer, the pilot drill rod for the pilot hole, the bottom section of the pile frame (the pile frame is composed of multiple steel frames vertically spliced ​​together; the bottom section is one or more steel frames at the bottom of the pile frame; the number of sections to be removed can be selected according to the actual situation, in principle avoiding interference between the pile frame and the bridge piles on the travel route), and auxiliary legs, etc. After dismantling, the integrated machine retreats to exit the closure section 6, leaving the closure section 6 completely reserved for the other integrated machine to carry out subsequent construction. The other integrated machine can enter the closure section 6 along the original through-hole direction to carry out pile driving and beam construction in sequence. After the last span of bridge piles in the closure section 6 is completed, the components of the pile driving system 3 on the other integrated machine can also be dismantled. After dismantling, the integrated machine can continue to move forward through the hole and complete the beam construction of the remaining part of the closure section 6 (i.e., the bridge piles for which the beam has not yet been constructed). At this point, the construction of the closure section 6 is completed. Then, the integrated machine can exit the closure section 6 forward or backward to complete the overall closure of the bridge. The closure method adopted in this invention can promptly dismantle the pile driving system 3 and auxiliary legs that may cause interference after the integrated pile and beam machines on both sides have completed their respective pile driving operations, and control one integrated machine to retreat to make room for the other integrated machine to complete the construction of the closure section 6. This can ensure work efficiency while avoiding the risk of interference from components such as the pile driving system 3, thus improving work safety.

[0058] In this embodiment, in step S2 above, if the pile hammer, pilot drill rod, pile frame bottom section and auxiliary support legs of the second pile-beam integrated machine 2 are removed, and the closure section 6 includes a third preset pile position 7, then in step S3 above, the first pile-beam integrated machine 1 is used to complete the pile driving operation of the third preset pile position 7 along the first through hole direction, and the first pile-beam integrated machine 1 is used to complete the beam construction between the first preset pile position 4 and the third preset pile position 7.

[0059] Alternatively, in step S4 above, the pile hammer, pilot drill rod, pile frame bottom section, and auxiliary support legs of the first integrated pile beam machine 1 are removed.

[0060] Alternatively, in step S5 above, the first pile-beam integrated machine 1 is used to complete the beam construction between the third preset pile position 7 and the second preset pile position 5 along the first through-hole direction.

[0061] After both integrated pile drivers reach their respective preset pile positions, the piling system 3 on one of the integrated pile drivers can be removed. For example, the piling system 3 of the second integrated pile-beam machine 2 can be removed and moved outside the closure section 6. The first integrated pile-beam machine 1 can then be used to continue the pile driving and beam construction in the closure section 6. The method described above, which involves first removing the second integrated pile-beam machine 2 and then using the first integrated pile-beam machine 1 to construct the closure section 6, is called... Figures 1-4 In the scheme shown, specifically, the second pile-beam integrated machine 2 first completes the piling, cap beam erection, and double T-beam installation at pile position 76. Then, the pile hammer, pilot drill rod, pile frame bottom section, and auxiliary support legs of the second pile-beam integrated machine 2 are dismantled. The dismantled parts are transported to the warehouse for storage by the trolley on the second pile-beam integrated machine 2. The first pile-beam integrated machine 1 completes the piling, cap beam erection, and double T-beam installation at pile position 74.

[0062] In this embodiment, in step S2 above, if the pile hammer, pilot drill rod, pile frame bottom section and auxiliary support legs of the first pile-beam integrated machine 1 are removed, and the closure section 6 includes the third preset pile position 7, then in step S3 above, the second pile-beam integrated machine 2 is used to complete the pile driving operation of the third preset pile position 7 along the second through hole direction, and the second pile-beam integrated machine 2 is used to complete the beam construction between the second preset pile position 5 and the third preset pile position 7.

[0063] Alternatively, in step S4 above, the pile hammer, pilot drill rod, pile frame bottom section, and auxiliary support legs of the second integrated pile beam machine 2 are removed.

[0064] Alternatively, in step S5 above, the second pile-beam integrated machine 2 is used to complete the beam construction between the third preset pile position 7 and the first preset pile position 4 along the second through-hole direction.

[0065] Similarly, the piling system 3 of the first integrated pile and beam machine 1 can be removed and moved outside the closure section 6, and then the second integrated pile and beam machine 2 can be used to continue the pile driving and beam construction in the closure section 6.

[0066] In this embodiment, step S3 further includes: retracting the pile-beam integrated machine that has undergone the dismantling step S2 to a preset dismantling area (not shown in the figure), and dismantling the pile-beam integrated machine in the preset dismantling area using a crawler crane (not shown in the figure).

[0067] Step S6 above also includes: moving the pile-beam integrated machine that has undergone the dismantling step S4 above to a preset dismantling area, and dismantling the pile-beam integrated machine in the preset dismantling area by means of a crawler crane.

[0068] The dismantling area can be set at the abutments at both ends of the bridge. It can be set at either end of the bridge or at both ends of the bridge. The dismantling equipment can include crawler cranes, cranes, hoists and other lifting equipment.

[0069] Step S2 above also includes: using the overhead crane on the dismantled pile-beam integrated machine to lift the dismantled components onto a carrier (not shown in the figure), the carrier is parked on the bridge and corresponds to the tail of the pile-beam integrated machine, and then the dismantled components are transferred using the carrier.

[0070] The integrated machine that first dismantles the piling system 3 can use cranes or other lifting equipment to place the dismantled parts onto a carrier located at the rear of the integrated machine. The carrier can be a transport flatbed truck, truck, or other transport equipment, and then the dismantled parts can be transported by the carrier to a designated storage location, such as a warehouse.

[0071] In this embodiment, the beam construction in steps S3 and S5 includes:

[0072] C1: A cap beam is erected on top of the bridge piles formed during the pile driving operation;

[0073] C2: Install double T-beams between bridge piles spaced along the direction of the span, with the double T-beams erected on top of the cap beam.

[0074] The two ends of the double T-beams are erected between the cap beams at the top of the two spans of the bridge piles, and multiple double T-beams are arranged along the width of the bridge.

[0075] In this embodiment, step S2 further includes: using the overhead crane on the pile-beam integrated machine after dismantling in S2 to transport the dismantled parts in S2 and place them on the constructed beam;

[0076] The above step S4 also includes: using the overhead crane on the pile-beam integrated machine after dismantling in S4 to lift the components dismantled in S2 and S4 and place them on the vehicle. The vehicle is parked on the bridge and corresponds to the tail of the pile-beam integrated machine after dismantling in S4. Then, the dismantled components are transferred using the vehicle.

[0077] In the above-mentioned closure construction steps, it is necessary to dismantle the piling system 3 and other components of the two integrated machines one after the other. After dismantling the piling system 3 of the first integrated machine, the dismantled components can be placed on the beam at the rear of the integrated machine. When the second integrated machine is dismantled, the components dismantled from both integrated machines can be hoisted onto a carrier by the overhead crane of the second integrated machine for transportation together. This can save one transportation step, improve the efficiency of process connection, and thus improve the overall construction efficiency.

[0078] It should be noted that the structure of the integrated pile and beam machine, such as the structure of the pile driving system 3, the legs, the pilot hole drill rod, etc., has been disclosed by prior patent applications, such as patents with publication numbers CN119465784A, CN116289585A and CN114592800A, and belongs to the prior art in this field.

[0079] In summary, this invention provides a bridge closure construction method. Two integrated pile-beam machines operate from both ends of the bridge towards the middle, allowing for pre-determined location and extent of the closure section. For example, the closure section includes at least the area between a first and a second pre-set pile position. These first and second pre-set pile positions can be the locations of the last bridge piles driven by the two integrated pile-beam machines at their closest points. The two integrated pile-beam machines can first drive to the first and second pre-set pile positions, completing the pile driving operation at these positions. To prevent the two integrated pile-beam machines from interfering with the pile driving systems on both sides by continuing to approach each other, some components of the pile driving system on one side of the integrated pile-beam machine can be removed, such as the pile hammer, the pre-drill rod for pilot holes, the bottom section of the pile frame (to avoid interference between the pile frame and bridge piles along the travel path), and auxiliary support legs. The dismantled integrated machine is then moved back to exit the closure section, completing the closure. The first section is completely reserved for the other integrated machine to carry out subsequent construction. The other integrated machine can enter the closure section along the original through-hole direction to carry out pile driving and beam construction in sequence. After the last span of bridge piles in the closure section is completed, the pile driving system components on the other integrated machine can be removed. After removal, the integrated machine can continue to pass through the hole and complete the beam construction of the remaining part of the closure section (i.e., the bridge piles for which the beam has not yet been constructed). At this point, the closure section construction is completed. Then, the integrated machine can be withdrawn forward or backward from the closure section to complete the overall closure of the bridge. The closure method adopted in this invention can promptly remove the pile driving system and auxiliary legs that may cause interference after the integrated pile and beam machines on both sides have completed their respective pile driving operations. It can also control one integrated machine to retreat to make room for the closure section so that the other integrated machine can complete the closure section construction. This can ensure work efficiency while avoiding the risk of interference from components such as the pile driving system, thus improving work safety.
