Description

Technical Field

[0001] This invention relates to the field of diaphragm wall construction technology, specifically to an integrated transport and erection support system and a construction method for diaphragm wall steel box support. Background Technology

[0002] Diaphragm walls have advantages such as high wall rigidity, strong load-bearing capacity, and good durability, and are often used as the support foundation structure for gravity anchorages of bridges.

[0003] Currently, the latest structural design for diaphragm walls in China for the first phase of the project adopts a steel box structure. Due to the length and weight of the steel box structure, it needs to be manufactured and assembled in sections during construction. In the existing technical solution, the steel box is manufactured in sections in the processing plant, transported to the construction site by special transport vehicles, then lifted to the construction position by two crawler cranes, and finally erected and installed by a single crawler crane.

[0004] The limitations of existing steel box transportation and erection technologies are as follows:

[0005] Special transport vehicles need to transport the steel boxes to a specific location on site, and then two crawler cranes lift the steel boxes to the construction position. This increases the lifting process, the cost of the crawler cranes, and reduces the efficiency of steel box operation and construction. Furthermore, the lifting operation itself is inherently risky and poses a challenge to the safety of the construction project.

[0006] Because the steel boxes need to be welded together during the docking process, which takes a long time, a crawler crane is required to lift and erect the steel boxes throughout the docking and welding process, with the help of guy ropes for temporary fixation. However, bridge construction often faces weather changes such as wind and rain. The crawler crane lifting is a flexible lifting method, and the guy ropes are also a flexible fixing structure, which does not provide rigid support for the steel boxes. Therefore, this method can only be used in light winds or gentle breezes, which has certain limitations and low safety.

[0007] Meanwhile, during windy weather, for safety reasons, crawler cranes cannot carry out steel box erection work, so work needs to be stopped, resulting in wasted construction time and increased construction costs.

[0008] Before the steel box is welded, its position needs to be adjusted to ensure the verticality of the construction. In the existing method, after the crawler crane erects the steel box vertically, the position of the steel box is adjusted by manually pulling ropes in combination with the total station detection. The adjustment accuracy is low and the risk is high.

[0009] In summary, the first phase of the new diaphragm wall steel box structure lacks corresponding supporting equipment systems during transportation and erection. Existing equipment technologies and processes have low construction safety, low equipment utilization, high equipment costs, and poor adaptability to weather conditions.

[0010] In order to improve or solve at least one of the above problems, a support device or apparatus is needed to support the construction of the steel box. Summary of the Invention

[0109] Step 4: In manual driving mode, use transport vehicle 3 to transport the multi-functional transport support frame 2 and steel box 1 to the construction site. Align the hinge plate 203 of the multi-functional transport support frame 2 with the hinge ear plate 406 of the movable adjustment platform 4 to complete the rough positioning of the multi-functional transport support frame 2. At this time, the slide 408 and the track 401 are in a fixed state, that is, the movable adjustment platform 4 cannot move along the track 401. Figure 16 As shown;

[0110] Step 5: Based on the position of the hinge plate 406 on the mobile adjustment platform 4, under the combined drive of automatic walking mode and manual driving mode, align the hinge plate 203 on the lower side of the multi-functional transport support frame 2 with the assembly hole of the hinge plate 406 on one side of the mobile adjustment platform 4 to complete the precise positioning of the multi-functional transport support frame 2. Record the Beidou coordinates of the transport vehicle 3 at this time, and then pass the connecting pin 407 through the hinge plate 406 and the hinge plate 203; at this time, the vertical telescopic column 405 of the mobile adjustment platform 4 is in a high position, such as... Figure 17 As shown;

[0111] Step Six: First, remove the positioning pin 307 to detach the multi-functional transport support frame 2 from the transport vehicle 3; second, use the crawler crane 7 to connect to the top of the multi-functional transport support frame 2 and apply tension; then, all the multi-functional walking modules 305 of the transport vehicle 3 operate, lowering the vehicle body; at this time, the multi-functional transport support frame 2 detaches from the transport vehicle 3, one end is hinged to the movable adjustment platform 4, and the other end is lifted by the crawler crane 7, as shown... Figure 18 As shown;

[0112] Step Seven: First, the transport vehicle 3 departs, and the crawler crane 7 lifts it. Since the other end of the multi-functional transport support frame 2 is already hinged to the movable adjustment platform 4, it will gradually be adjusted from a horizontal state to a vertical state under the action of the crawler crane 7. Second, align the hinge plate 203 on the other side with the mounting hole of the hinge ear plate 406 on the other side of the movable adjustment platform 4, and use the connecting pin 407 to pass through the hinge ear plate 406 and the hinge plate 203. At this time, the multi-functional transport support frame 2 is completely assembled with the movable adjustment platform 4 as one unit. Figure 19 As shown;

[0113] Step 8: The crawler crane 7 releases its hook, the automatic leveling system of the moving adjustment platform 4 operates, and simultaneously the vertical telescopic column 405 descends, adjusting the steel box 1 to a position where it is welded to the lower steel box 6. Figure 20 As shown;

[0114] Step Nine: First, weld the steel box 1 to the lower steel box 6 to form a complete first-phase steel box structure. The crawler crane 7 then lifts the vertical lifting lugs 105 of the steel box 1. Second, remove the magnetic attraction from all the electrically controlled permanent magnet chucks 204 of the multi-functional transport support frame 2, and retract all the lateral support arms 202. Then, lower all the vertical telescopic columns 405 of the moving adjustment platform 4 to their lowest position. At this point, the multi-functional transport support frame 2 is completely detached from the steel box 1, and the steel box 1 is mainly lifted by the crawler crane 7. Next, the rotary motor 206 on the multi-functional transport support frame 2 activates, lifting the rotating beam 207. Then, loosen the slide 408 from the track 401, and move the moving adjustment platform 4 outward along the track 401 as a whole. Figure 21 As shown;

[0115] Step 10: The crawler crane 7 lowers the entire first-phase steel box structure into the trough section 5, as follows: Figure 22 As shown;

[0116] Step 11: First, the rotary motor 206 on the multi-functional transport support frame 2 actuates, retracting the rotating beam 207; then, the movable adjustment platform 4 moves back to its original position, securing the slide 408 to the track 401, and is then lifted by the crawler crane 7 to the top of the multi-functional transport support frame 2; next, the connecting pin 407 on the right side is removed, and the transport vehicle 3 is automatically driven to the Beidou coordinate position recorded in step five; then, the crawler crane 7 gradually lowers the multi-functional transport support frame 2 from a vertical state to a horizontal state; then, all the multi-functional walking modules 305 of the transport vehicle 3 operate, adjusting the height of the transport vehicle 3 so that it contacts the lower surface of the multi-functional transport support frame 2, and then the positioning pin 307 is installed, completing the assembly of the transport vehicle 3 and the multi-functional transport support frame 2; finally, the connecting pin 407 (on the left side) that mates with the multi-functional transport support frame 2 and the movable adjustment platform 4 is removed, disengaging the mate between the multi-functional transport support frame 2 and the movable adjustment platform 4, as shown below. Figure 23 As shown;

[0117] Finally, transport vehicle 3 drove out of the construction site, completing the single-round transport and erection of steel box 1, and can continue to drive into the processing plant for the next round of steel box transport and erection.

[0118] In addition, the supplementary explanations for this technical solution are as follows:

[0119] The lower steel box 6 is a steel box that is hoisted down from the lower section. It does not require long-term welding work or continuous support. Therefore, the above construction steps, excluding the alignment and butt welding of steel box 1 and lower steel box 6, are the transportation and erection plan for lower steel box 6.

[0120] In step seven, after the transport vehicle 3 leaves, it can continue to work in other places or transport other steel boxes, which increases the utilization rate of the idle time of the transport vehicle 3.

[0121] This invention aims to address the limitations of existing diaphragm wall steel box transportation and erection equipment and processes, which result in low construction safety, low equipment utilization, high equipment costs, and poor weather adaptability. It proposes an integrated diaphragm wall steel box transportation and erection system and its construction method. This system uses entirely new equipment and methods to transport and erect diaphragm wall steel boxes, improving the efficiency of special equipment use, enhancing construction safety and efficiency, eliminating the lifting process, improving the vertical adjustment accuracy of the steel boxes, and enhancing the adaptability of diaphragm wall steel box construction to adverse weather conditions. This ensures construction progress and saves project construction costs.

[0122] The main contents are as follows:

[0123] The transport support frame disclosed in this invention integrates an electrically controlled permanent magnet chuck, a telescopic arm, and a rotating beam, enabling effective fixation and erection of steel boxes. During steel box transport, the multi-functional transport support frame can be used in conjunction with transport vehicles for support and transport. During steel box erection, the multi-functional transport support frame can be used in conjunction with crawler cranes and mobile adjustment platforms for erection and support, allowing steel box construction to be carried out using a single crawler crane, reducing the equipment cost of the crawler crane. By reducing the lifting process, the safety of steel box construction is ensured, and the construction efficiency of steel box erection is improved. Simultaneously, with the support of the multi-functional transport support frame, the steel box does not require continuous lifting by the crawler crane during the butt welding process, improving the equipment utilization rate of the crawler crane. Furthermore, the use of the multi-functional transport support frame for rigid support and erection of the steel box enhances the safety of the steel box during the butt welding process and improves the adaptability of steel box construction to weather conditions.

[0124] The transport vehicle adopts a wheeled self-drive mobile form and is equipped with hydraulic active suspension. Combined with the Beidou navigation system, it can effectively adapt to the usage requirements of on-site construction, realize the precise positioning and self-movement of the transport vehicle, and facilitate the precise alignment of the steel box.

[0125] The mobile adjustment platform adopts a four-point independent support lifting structure, combined with a dual-axis tilt sensor installed on the steel box, which can effectively adjust the position and posture of the steel box, ensure the verticality of the steel box, and improve the construction accuracy of the steel box.

[0126] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
