Description

Technical Field

[0001] The present application relates to the technical field of wharf construction, and in particular to a construction process for rapidly erecting prefabricated wharf components using a bridge erection machine. Background Art

[0002] During dock construction, cranes are usually installed using truck cranes, gantry cranes, floating cranes, or tower cranes. However, when the area to be constructed is large, gantry cranes and tower cranes are difficult to adapt to. Floating cranes have low lifting efficiency and are greatly affected by tidal currents, making them less stable. Truck cranes require construction of a portion of the area before they can proceed with subsequent lifting using the area already constructed, resulting in a longer construction period.

[0003] Therefore, there is an urgent need for a construction technology that can adapt to large-scale construction of docks. Summary of the Invention

[0016] By adopting the above technical solution, the coordination between the anchor rod and the anchor device generates tension on the mooring member, so as to facilitate the coordination of the lower support assembly to form an effective support fixation. At the same time, the anchor device can adjust its position to better coordinate with the anchor rod.

[0017] Optionally, the anchor includes an anchor block, an anchor barrel and an anchor plate, the anchor block is connected to the positioning channel steel, two anchor barrels are provided, and both are hinged to the anchor block, the two anchor barrels are semicircular, the side wall of the anchor barrel is provided with a conical surface, each of the anchor barrels is provided with a plurality of anchor plates, and the plurality of anchor plates slide on the conical surface along the axis of the anchor barrel; the anchor barrel has a closed state and an open state, when the anchor barrel is in the closed state, the two anchor barrels form a cylindrical shape, and the plurality of anchor plates anchor the anchor rod, and a locking member is provided between the two anchor barrels for maintaining the anchor barrel in a closed state.

When the two anchor cylinders enter the closed state, the chute and the clamping slot are aligned, and the slider is in both the clamping slot and the chute, thereby locking the two anchor cylinders. The compression spring is used to prevent the slider from leaving the clamping slot, and the lever is used to adjust the position of the slider so that the slider can leave the clamping slot, thereby facilitating the separation of the two anchor cylinders into the open state. 9. First hoist the mooring component in the vertical direction, and then move the component horizontally. This can improve the placement accuracy of the mooring component and make it easier to put the second steel bar on the first steel bar.

[0046] Example 1 A construction process for quickly erecting prefabricated components of a wharf using a bridge erection machine, referring to Figure 1 To Figure ,4, the following steps are included: S1, sinking the PHC piles 1 to form a bent frame, and then constructing the lower cross beams 2 on the PHC piles 1 to form several rows of lower cross beams 2; S2, assembling the bridge erection machine 3, the hydraulic legs 32 of the bridge erection machine 3 are supported on the lower crossbeam 2, and the bridge erection machine 3 can move along the arrangement direction of the lower crossbeam 2; S3, hoisting the prefabricated longitudinal beam components 4 by the bridge erection machine 3, placing the prefabricated longitudinal beam components 4 on the lower cross beam 2, with both ends of each prefabricated longitudinal beam component 4 respectively placed on two adjacent lower cross beams 2; S4. Construction: Construct the upper crossbeam 6 (the yellow part in the figure is the upper crossbeam 6) on the lower crossbeam 2, so that the upper crossbeam 6, the lower crossbeam 2 and the prefabricated longitudinal beam member 4 form a whole; S5. Hoist the prefabricated panel 5 by the bridge-erecting machine 3, place the prefabricated panel 5 on the prefabricated longitudinal beam and the upper cross beam 6, and connect the prefabricated panel 5 with the prefabricated longitudinal beam and the upper cross beam 6.

[0047] After the cast-in-place lower crossbeam 2 is formed, the prefabricated longitudinal beam component 4 is quickly hoisted by using the bridge-erecting machine 3, and then the upper crossbeam 6 is cast in place, so that the lower crossbeam 2 and the prefabricated longitudinal beam component 4 are formed into one body, and then the prefabricated panel 5 is hoisted by the bridge-erecting machine 3. The combination of cast-in-place structure and prefabricated components can achieve rapid construction while ensuring construction quality. The bridge-erecting machine 3 can greatly improve the hoisting efficiency of prefabricated components, and the bridge-erecting machine 3 can work simultaneously while the upper crossbeam 6 is cast in place, further improving construction efficiency.

[0048] Specifically, in step S4, the mooring member 7 is hoisted, and a connecting section 22 is cast between the mooring member 7 and the corresponding lower crossbeam 2 to form an integral body with the mooring member 7. The mooring member 7 is prefabricated to improve construction efficiency. The mooring member 7 is then connected to the lower crossbeam 2 via the cast-in-place connecting section 22, thereby improving construction efficiency while ensuring the connection strength between the mooring member 7 and the lower crossbeam 2.

[0049] More specifically, refer to Figures 5 to 10 When pouring the connecting section 22, the connecting section 22 is poured through the connecting mold 8. The connecting mold 8 includes a positioning channel steel 81, an upper pull assembly 82 and a lower support assembly 84. Two positioning channel steels 81 are provided, and both are installed on the lower crossbeam 2. One end of the upper pull assembly 82 is connected to the positioning channel steel 81, and the other end is connected to the mooring member 7. One end of the lower support assembly 84 is connected to the PHC pile 1, and the other end is connected to the mooring member 7. The upper pull assembly 82 cooperates with the lower support assembly 84 to achieve temporary fixation of the mooring member 7, so that the connecting section 22 can be poured to ensure construction safety. The positioning channel steel 81 and the lower crossbeam 2 are temporarily provided with an I-beam 811. At the same time, the positioning channel steel 81 is connected to the embedded screw 812 on the lower crossbeam 2 through a nut to achieve the fixation of the positioning channel steel 81.

[0050] The top of the docking member 7 is connected to a first formwork 71, a second formwork 72, and a third formwork 73. A casting area for casting the connecting section 22 is formed between the first formwork 71, the second formwork 72, the third formwork 73, and the side wall of the lower cross beam 2. A lifting ring is connected to the side wall of each of the first formwork 71 and the third formwork 73, so that the docking member 7 can be hoisted by the bridge erection machine 3. When the bridge erection machine 3 hoists the docking member 7, the bridge erection machine 3 is connected to the two lifting rings through two lifting ropes, and the two lifting ropes are located on the outside of the two positioning channel steels 81. The first formwork 71, the second formwork 72, and the third formwork 73 are set on the docking member 7, and the top surface of the docking member 7 is used as the bottom formwork, and the side wall of the lower cross beam 2 is used as the side formwork, which saves materials, ensures the accuracy of the formwork, and improves construction efficiency and quality.

[0051] The lower support assembly 84 includes a clamp 841, a first screw sleeve 842 and a first screw rod 843. The clamp 841 is fixedly connected to the PHC pile 1. One end of the first screw sleeve 842 is hinged to the mooring assembly, and the other end is threadedly connected to the first screw rod 843. The end of the first screw rod 843 away from the first screw sleeve 842 is ball-jointed with the clamp 841. The first screw rod 843 is fixedly connected to the first rotating nut 844. During installation, the clamp 841 is first fixedly installed on the PHC pile 1, and then the first rotating nut 844 is used to adjust the distance between the first screw sleeve 842 and the first screw sleeve 842. The first screw sleeve 842 is then connected to the hole reserved for the mooring member 7. At the same time, the first rotating nut 844 can be further adjusted to form an effective support for the mooring member 7.

[0052] The pull-up assembly 82 includes an anchor rod 834 and an anchor. The anchor rod 834 is fixedly connected to the mooring member 7. The anchor is provided on the positioning channel steel 81. The anchor can be adjusted relative to the positioning channel steel 81 along the width direction of the positioning channel steel 81. The anchor is used to anchor the anchor rod 834. The cooperation between the anchor rod 834 and the anchor generates a pulling force on the mooring member 7, so that the lower support assembly 84 cooperates to form an effective support and fixation. At the same time, the anchor can be adjusted to better cooperate with the anchor rod 834.

[0053] The anchor system includes an anchor block 821, an anchor cylinder 832, and anchor plates 833. The anchor block 821 is connected to the positioning channel steel 81. Two anchor cylinders 832 are provided, both hingedly connected to the anchor block 821. A movable rod 8211 is fixedly connected to the anchor block 821, and a fixed block 813 is fixedly connected to the positioning channel steel 81. The movable rod 8211 is inserted through the fixed block 813, and a bolt is threaded onto the fixed block 813 to lock the movable rod 8211. Both anchor cylinders 832 are semicircular in shape, with a tapered surface 8321 on their sidewalls. Each anchor cylinder 832 is equipped with multiple anchor plates 833. These multiple anchor plates 833 slide along the axis of the anchor cylinder 832 on the tapered surface 8321, and the outer walls of the anchor plates 833 are aligned with the tapered surface 8321 of the anchor cylinder 832. A T-shaped block 8331 is fixedly connected to the outer wall of the anchor plate 833. A T-shaped slot 8322 is provided on the conical surface 8321 of the anchor barrel 832 for the T-shaped slider 8354 to slide, allowing the anchor plate 833 to slide relative to the anchor barrel 832. The anchor barrel 832 has a closed state and an open state. When the anchor barrel 832 is in the closed state, the two anchor barrels 832 form a cylindrical shape, and the multiple anchor plates 833 anchor the anchor rod 834. A locking member 835 is provided between the two anchor barrels 832 to maintain the closed state of the anchor barrels 832. After the mooring member 7 is moved into position, the anchor barrel 832 is moved again and switched from the open state to the closed state to lock the anchor rod 834. The anchor rod 834 does not need to be passed through the anchor barrel 832 along its axial direction. The anchor barrel 832 can be installed from one side of the anchor rod 834, improving installation convenience.

[0054] The locking piece 835 includes a locking cover 8351 and a locking block 8352. The locking cover 8351 is fixedly connected to one anchor cylinder 832, and the locking block 8352 is fixedly connected to the other anchor cylinder 832. A sliding groove 8353 is provided on the locking block 8352, and a slider 8354 slides in the sliding groove 8353. The locking cover 8351 is provided with a slot 8358 for the slider 8354 to be inserted, and a compression spring 8355 is provided in the sliding groove 8353. One end of the compression spring 8355 abuts against the end of the slider 8354 away from the slot 8358, and the other end abuts against the end of the sliding groove 8353 away from the slot 8358. A detent rod 8356 is fixedly connected to the side wall of the slider 8354, and the end of the detent rod 8356 away from the slider 8354 passes through the locking block 8352, and the locking block 8352 is provided with a detent groove 8357 for the detent rod 8356 to slide. After the two anchor cylinders 832 enter the closed state, the slide groove 8353 is aligned with the card slot 8358, and the slider 8354 is in the card slot 8358 and the slide groove 8353 at the same time, thereby locking the two anchor cylinders 832. The compression spring 8355 is used to prevent the slider 8354 from disengaging from the card slot 8358, and the lever 8356 is used to facilitate the adjustment of the position of the slider 8354 so that the slider 8354 disengages from the card slot 8358, thereby facilitating the separation of the two anchor cylinders 832 and entering the open state.

[0055] In addition, a diagonal brace 74 is hingedly connected to the mooring member 7. The end of the diagonal brace 74, which is away from the mooring member 7, is hingedly connected to the side wall of the lower crossbeam 2. The diagonal brace 74 can further enhance the stability of the mooring member 7. At the same time, the diagonal brace 74 also serves as the skeleton of the connecting section 22, improving the strength and reliability of the connection between the connecting section 22, the lower crossbeam 2, and the mooring member 7. After construction is completed, the positioning channel steel 81 and the upper pull assembly 82 are removed, but the lower support assembly 84 is not removed.

[0056] It should be noted that a horizontally arranged first steel bar 21 is reserved on the side wall of the lower cross beam 2, and a vertically arranged second steel bar 75 is reserved on the top surface of the docking member 7. The second steel bar 75 is in an inverted U shape. When the docking member 7 is hoisted, the docking member 7 is hoisted until the top surface of the first template 71 is flush with the top surface of the lower cross beam 2, and then the docking member 7 is moved horizontally toward the lower cross beam 2 until the first template 71 and the third template 73 abut against the lower cross beam 2. During the horizontal movement of the docking member 7, the first steel bar 21 is inserted into the second steel bar 75, and the first steel bar 21 and the second steel bar 75 are connected by steel wire binding.

[0063] By moving the bridge-building machine 3 on the lower beam 2, stable and reliable lifting on the water surface can be achieved. At the same time, the detachable module can be connected with different clamps 39 to adapt to different prefabricated components, further improving the lifting efficiency and safety.

[0064] Specifically, in step S1, when assembling the bridge frame 31, three main beams are first assembled, and then the bridge frame 31 is moved away from the shore. New main beams are then installed on the shore, and the bridge frame 31 is then moved again, and this process is repeated until all the main beams of the bridge frame 31 are installed. Installing new main beams on the shore is more convenient and safer. By continuously moving the bridge frame 31 forward to provide installation space for the new main beams, the bridge frame 31 can be assembled in a smaller space, further ensuring the convenience of construction.

[0065] In step S3 , after the bridge erection machine 3 is completely separated from the shore, the upper crossbeam 6 is cast synchronously on the rear side. When the bridge erection machine 3 hoists the prefabricated panel 5 , the hydraulic support legs 32 are supported on the prefabricated longitudinal beam component 4 or the upper crossbeam 6 .
