Description

Technical Field

[0001] The present invention relates to the technical field of wharf construction, and in particular to a method for erecting an assembled high-pile wharf. Background Art

[0002] Prefabricated construction, a new trend, has been gradually adopted in the field of wharf construction. Prefabricated wharf construction involves hoisting prefabricated components (such as prefabricated beams and prefabricated panels) between pre-arranged lower beams of the wharf, completing the erection of the prefabricated wharf.

[0003] Docks are typically tens of meters from the shore, connected by approach bridges. Currently, prefabricated components are often transported to the dock's designated location for installation using floating cranes. These cranes rise and fall with the waves, which can easily cause the lifted components to collide with other equipment on the construction site or leave prefabricated components suspended in the air after being lowered but not yet released from the lifting gear. Consequently, the current method of suspending prefabricated components is significantly affected by sea conditions, resulting in poor installation accuracy and an inability to guarantee continuous construction, impacting the efficiency and safety of dock construction.

[0063] Example 1

[0064] A pier is arranged at shore 16, with the pier being several hundred meters long and its length (hereinafter referred to as the pier direction) roughly parallel to the shore. Within the pier construction area (hereinafter referred to as the pier area), multiple pier lower crossbeams 12 are pre-placed, spaced along the pier direction. The length of the pier lower crossbeams 12 is roughly perpendicular to the pier direction, and the distance between two adjacent pier lower crossbeams 12 is one span. The pier lower crossbeams 12 can be constructed from shore 16 to the pier area, so they are not subject to, or are not excessively subject to, the effects of sea conditions.

[0065] The longitudinal direction is the direction of the wharf, and the length direction of the beam 12 under the wharf is the transverse direction.

[0066] This embodiment provides a method for erecting an assembled high-pile wharf, which uses an integrated device for erecting beams and slabs of a high-pile wharf. Figure 1 As shown, it includes a crossbeam 4, supporting legs, a longitudinal beam 2 and a lifting trolley 1; wherein, when the equipment is erected and used, the longitudinal beam 2 is arranged longitudinally and the crossbeam 4 is arranged transversely.

[0067] Wherein, the longitudinal beam 2 is arranged on the top of the cross beam 4, and the longitudinal beam 2 can move on the cross beam 4 along the length direction (transverse direction) of the cross beam 4, wherein the longitudinal beam 2 can be moved transversely on the cross beam 4 by arranging a running mechanism 3 at the bottom of the longitudinal beam 2, wherein the running mechanism 3 is provided with a transverse moving wheel, and the transverse moving wheel is in rolling cooperation with the guide rail at the top of the cross beam 4; the hoisting trolley 1 is arranged on the top of the longitudinal beam 2, and the hoisting trolley 1 can move on the longitudinal beam 2 along the length direction (longitudinal direction) of the longitudinal beam 2, at this time, the hoisting trolley 1 can move longitudinally and transversely between the two ends of the cross beam 4 and the two ends of the longitudinal beam 2. Wherein, as Figure 3 、 Figure 4 As shown, the cross beam 4 is located under the longitudinal beam 2 at the middle beam section of the longitudinal beam 2, and the length of the longitudinal beam 2 is close to 3 times the width of each support leg in the longitudinal direction, so that the hoisting trolley 1 can at least move on the longitudinal beam 2 to both sides of all supports in the longitudinal direction.

[0068] At least three of the legs are distributed along the length direction of the beam 4 and are arranged at the bottom of the beam 4, so as to support the beam 4 and its upper parts and keep them away from the sea surface. The length of the legs is adjustable, and the adjustment method can be to set a jack at the bottom of the leg and adjust the length of the leg by raising and lowering the jack.

[0069] The tops of at least two of the legs can move along the length direction of the beam 4. If the legs are movable legs, a reverse roller device 10 can be provided on the tops of the movable legs, and the reverse roller device 10 is installed on the beam 4; the movable legs are connected to the beam 4 through the reverse roller device 10 to support the beam 4. At the same time, the reverse roller device 10 serves as a driving mechanism, and the reverse roller device 10 rotates to realize the relative transverse movement of the beam 4 and the movable legs, that is, when the beam 4 is stationary, the movable legs are driven to move transversely along the beam 4 by the reverse roller device 10, and when the movable legs are stationary, the beam 4 is driven to move transversely by the reverse roller device 10.

[0070] The bottom of the support leg can move longitudinally through the track 9, and the support leg can be in contact with the track 9 through the wheel box 11. The track 9 is extended longitudinally and the movement of the support leg on the track 9 is achieved through the wheel box 11.

[0071] The following steps are involved:

[0072] A1. Setting up equipment on the shore 16. The setting up method may be transportation or on-site assembly;

[0073] A2. Using the lower crossbeam 12 of the wharf as a foothold, the equipment is driven by the multiple legs to move from the shore 16 toward the wharf area until the front end of the crossbeam 4 in the equipment moves to the wharf area and the rear end of the crossbeam 4 is still located at the shore 16, so that the hoisting trolley 1 can lift the prefabricated parts from the shore 16 to the wharf area in the horizontal direction for installation;

[0074] A3. Use the hoisting trolley 1 to lay out the track 9 along the length of the wharf so that the bottom of the legs can drive the entire equipment to move along the length of the wharf. Use the hoisting trolley 1 to lift the prefabricated parts from the shore 16 to the wharf for installation until all the prefabricated parts are installed.

[0075] By adopting relevant equipment, the lifting and transportation of prefabricated parts between the shore 16 and the dock range can be realized, reducing or even avoiding the influence of waves on the prefabricated parts during transportation and installation; at the same time, through the cooperation of multiple legs and beams 4, the equipment can be moved to the area between the shore 16 and the dock range with the lower beam 12 of the dock as the foothold, which is convenient for the arrangement of the equipment, and the top of the lower beam 12 of the dock is located on the sea surface, so the equipment will not be excessively disturbed by waves when moving between the shore 16 and the dock range; at the same time, for the equipment that has been moved between the shore 16 and the dock range, the track 9 can be lifted to the support legs by the lifting trolley 1, so that the entire equipment can be subsequently moved along the length direction of the dock, so that the lifting trolley 1 can lift prefabricated parts over the entire dock range.

[0076] The entire process will not be overly affected by the waves, and the time required for hoisting, transporting and installing prefabricated parts is shorter. Moreover, based on large-scale construction of the entire wharf range, the cost of a single device is lower, thereby improving the construction efficiency and safety of the wharf erection.

[0077] In one or more embodiments, the legs that can move along the length direction of the beam 4 are defined as movable legs;

[0078] In step A2, the method of using the lower crossbeam 12 of the dock as a foothold and driving the device forward by the plurality of legs includes:

[0079] B1, wherein at least two movable legs support the crossbeam 4, and the remaining legs are shortened and suspended in the air, and the crossbeam 4 carries the remaining legs and moves forward along the length direction of the crossbeam 4 on the two movable legs;

[0080] B2, the remaining legs and one of the movable legs support the beam 4, the other movable leg is shortened and suspended in the air, and the other movable leg moves along the length direction of the beam 4 under the beam 4;

[0081] B3, the remaining legs and the other movable leg support the beam 4, one of the movable legs is shortened and suspended in the air, and the one of the movable legs moves along the length direction of the beam 4 under the beam 4;

[0082] B4. Through continuous cycles of steps B1-B3, the entire device moves forward along the length direction of the beam 4.

[0083] The footing of the legs supporting the beam 4 may be the beam 12 under the pier or the shore 16 depending on the location.

[0084] In one or more embodiments, the number of the support legs can be three, and the three support legs are respectively a front support leg 6, a middle support leg 7 and a rear support leg 8, and the front support leg 6, the middle support leg 7 and the rear support leg 8 are distributed in sequence from the front end to the rear end of the beam 4, wherein the front support leg 6 and the middle support leg 7 serve as movable support legs, that is, the top of the front support leg 6 and the middle support leg 7 can move along the length direction of the beam 4, and the rear support leg 8 is fixedly connected to the rear end of the beam 4.

[0085] Among them, the front support leg 6 and the middle support leg 7 will move to the sea surface. By moving the front support leg 6 and the rear support leg 8 relative to the beam 4, the front support leg 6 and the rear support leg 8 can be directly moved to a foothold on the beam 12 under the pier for easy rest. The rear support leg 8 is located at the rear end of the beam 4 and its position remains on the shore 16, so there is no need to make it movable.

[0086] Based on this, Figure 2 As shown, in step A2, the method of using the lower beam 12 of the dock as a foothold and driving the device forward by a plurality of legs includes:

[0087] B1, the front legs 6 and the middle legs 7 support the crossbeam 4, the rear legs 8 are shortened and suspended in the air, and the crossbeam 4 moves forward along the length direction of the crossbeam 4 with the rear legs 8 on the front legs 6 and the middle legs 7;

[0088] B2, the rear legs 8 and the middle legs 7 support the crossbeam 4, the front legs 6 are shortened and suspended in the air, and the front legs 6 move forward along the length direction of the crossbeam 4 under the crossbeam 4;

[0089] B3, the front legs 6 and the front legs 6 support the crossbeam 4, the middle legs 7 are shortened and suspended in the air, and the middle legs 7 move forward along the length direction of the crossbeam 4 under the crossbeam 4;

[0090] B4. Through continuous cycles of steps B1-B3, the entire device moves forward along the length direction of the beam 4. When the entire device moves to the desired position, all the legs support the beam 4 at the same time.

[0091] Among them, considering that during the process of hoisting the prefabricated parts to the dock area for installation, the hoisting trolley 1 and the longitudinal beam 2 both need to be moved to the corresponding position along the length direction of the cross beam 4, at which time the load on this part of the cross beam 4 is relatively large, therefore, in one or more examples, the front legs 6 can be moved to the side of the dock area farthest from the shore 16; the middle legs 7 can be moved to the side of the dock area closest to the shore 16, or the middle legs 7 can be moved between the dock area and the shore 16. In this case, the front legs 6 and the middle legs 7 are respectively located on both sides of the dock area, ensuring the support performance of the front legs and the middle legs 7 for the hoisting trolley 1 during the installation of the prefabricated parts at the dock area.

[0092] In one or more embodiments, the device may further include a front support member 5 , wherein the front support member 5 is fixed to the front end of the crossbeam 4 .

[0093] In step A2, when all the legs are located between the midpoint and the rear end of the beam 4 along the length direction, for example, when the front legs 6 and the middle legs 7 are located between the midpoint and the rear end of the beam 4 at a certain point in time when the equipment moves forward, when part of the beam section from the midpoint to the front end of the beam 4 is suspended in the air, the front support member 5 temporarily supports the suspended beam section from the midpoint to the front end of the beam 4 along the length direction.

[0094] Among them, the front support member 5 is only used to temporarily support the front end of the beam 4 when the front end of the beam 4 is suspended in the air, so as to avoid the equipment from tipping forward or excessive stress in the suspended part of the front end of the beam 4. It does not involve the subsequent support of the beam 4 during the transportation and installation of the prefabricated parts. Therefore, the load-bearing capacity requirements of the front support member 5 are relatively low, and the weight of the front support member 5 can be much lower than the front support leg 6, thereby reducing the load on the front end of the beam 4 when it is suspended in the process of moving from the shore 16 to the dock range, reducing the possible damage to the front end of the beam 4, or reducing the possibility of imbalance between the front and rear ends of the beam 4.

[0095] The front support member 5 may be a column without any other functional components.

[0096] In order to enable the entire equipment to move along the length direction of the wharf, in one or more embodiments, in step A1, when erecting the legs of the equipment, several sections of track 9 are detachably installed in advance at the bottom of each leg, wherein the length of each section of track 9 is one span, and the two ends of each section of track 9 can be directly placed on the lower cross beams 12 of two adjacent wharves. At this time, the overall length of the several sections of track 9 is adapted to the width of the legs in the longitudinal direction, so that the legs will not cause too much obstruction to the two ends of the track 9 at the bottom thereof, thereby facilitating the hoisting trolley 1 to add or reduce the track 9 at the end of the bottom track 9.

[0097] The several segments can be one segment, two ends, three segments or even more segments, wherein the figure shows two segments.

[0098] When the equipment moves to the corresponding position and supports the beam 4 through all the legs, the several sections of track 9 at the bottom of the legs also support the legs, and the length direction of the track 9 is parallel to the length direction of the dock.

[0099] In step A3, the method of laying the track 9 along the length direction of the wharf by the hoisting trolley 1 so that the bottom of the legs can drive the entire device to move along the length direction of the wharf includes:

[0100] C1. Use the hoisting trolley 1 to lift the other rails 9 from the shore 16 to the end of the rail 9 at the bottom of the support and splice them, so that the overall length of the rail 9 is increased, so that the production can move on the rail 9;

[0101] C2. All supports drive the entire device to move on the spliced ​​rails 9, so that the supports move above the other rails 9. At this time, the other rails 9 participate in supporting the supports, and the part of the rail 9 that was previously at the bottom of the support is exposed. At this time, the exposed part of the rail 9 does not support the supports and can be disassembled;

[0102] C3. Use the hoisting trolley 1 to lift the exposed part of the track 9 from one end at the bottom of the support to the other end and splice it;

[0103] C4. Repeat steps C2-C3 to move the entire device along the length of the dock.

[0104] Through this method, the entire equipment can be moved along the length direction of the wharf. The entire process fully utilizes the lifting function of the hoisting trolley 1, and there is no need to transport the track 9 separately, which will not be excessively disturbed by the waves. At the same time, in the process of the entire equipment moving along the length direction of the wharf, the track 9 is paved in a circular manner, and there is no need to use too much track 9, which greatly reduces the cost of laying the track 9. At the same time, considering that some prefabricated parts (such as prefabricated beams 13 and prefabricated panels 14) need to be laid between the adjacent wharf lower beams 12, by disassembling the track 9, it is possible to avoid obstruction of the corresponding prefabricated parts operation when the track 9 is erected on the two wharf lower beams 12.

[0105] To complete the installation of the prefabricated components, in one or more embodiments, in step A3, the method of lifting the prefabricated components from the shore 16 to the dock area by the hoisting trolley 1 for installation includes:

[0106] D1. Move the equipment to the first span (i.e., the position of the two adjacent lower cross beams 12 of the pier at the outermost edge), and use the hoisting trolley 1 to lift multiple prefabricated parts from the shore 16 to the position between the front legs 6 and the middle legs 7 for installation. During the installation process, the hoisting trolley 1 and the prefabricated parts are located between the front legs 6 and the middle legs 7, and can be stably supported by the front legs 6 and the middle legs 7. However, due to the obstruction of the front legs 6 and the middle legs 7, the hoisting trolley 1 is temporarily unable to lift the prefabricated parts to the position where the front legs 6 or the middle legs 7 are located for installation;

[0107] D2. Move the equipment one span along the length of the wharf so that the area blocked by the front legs 6 and the middle legs 7 in the previous step is no longer blocked by the front legs 6 and the middle legs 7. Use the hoisting trolley 1 to lift the prefabricated component to the area blocked by the front legs 6 and the middle legs 7 in the previous step for installation. During the installation process, the hoisting trolley 1 and the prefabricated component are on the side of the front legs 6 or the middle legs 7. Since this step requires less area to be installed and takes less time, the equipment will not be subjected to lateral loads for a long time.

[0108] D3. Use the hoisting trolley 1 to lift multiple prefabricated parts from the shore 16 to the space between the front support leg 6 and the middle support leg 7 for installation;

[0109] D4. Repeat steps D2-D3, installing prefabricated parts along the length of the wharf one by one with two spans as a cycle.

[0110] Among them, when the prefabricated parts include prefabricated beams 13 and prefabricated panels 14, the prefabricated beams 13 after installation need to be cast into one piece with the adjacent lower crossbeams 12 of the pier, and the prefabricated panels 14 are paved on the prefabricated beams 13 after the casting reaches the setting period, and other operations still need to be performed on the prefabricated panels 14 after the prefabricated panels 14 are paved.

[0111] Based on this, in the case where the prefabricated parts include prefabricated beams 13 and prefabricated panels 14, in one or more examples, in step A3, the method of lifting the prefabricated parts from the shore 16 to the dock area for installation by the hoisting trolley 1 includes:

[0112] D1. Move the equipment to the first span and use the hoisting trolley 1 to lift multiple precast beams 13 from the shore 16 to the space between the front legs 6 and the middle legs 7 for arrangement. The arranged precast beams 13 are then cast together with the adjacent lower cross beams 12 of the wharf to complete the installation of the precast beams 13.

[0113] D2. Move the equipment one span along the length of the wharf. Use the hoisting trolley 1 to lift the precast beam 13 to the area blocked by the front legs 6 and the middle legs 7 in the previous step. Then, cast the arranged precast beam 13 and the adjacent lower cross beam 12 of the wharf into one piece, thus completing the installation of the precast beam 13.

[0114] D3. Use the hoisting trolley 1 to hoist multiple precast beams 13 from the shore 16 to the space between the front legs 6 and the middle legs 7 for arrangement. The arranged precast beams 13 are then cast together with the adjacent lower cross beams 12 of the dock to complete the installation of the precast beams 13.

[0115] D4, repeat steps D2-D3;

[0116] D5. When the concrete poured between the precast beam 13 and the adjacent lower cross beam 12 reaches the setting period, the equipment is withdrawn, and multiple precast panels 14 are hoisted from the shore 16 to the precast beam 13 between the front support leg 6 and the middle support leg 7 by the hoisting trolley 1 for installation;

[0117] D6. Move the equipment one span along the length of the wharf, and use the hoisting trolley 1 to lift the prefabricated panel 14 to the prefabricated beam 13 at the area blocked by the front legs 6 and the middle legs 7 in the previous step for installation;

[0118] D7. Use the hoisting trolley 1 to lift multiple prefabricated panels 14 from the shore 16 to the prefabricated beam 13 between the front support leg 6 and the middle support leg 7 for installation;

[0119] D8, repeat steps D6-D7 until all prefabricated beams 13 have been installed with prefabricated panels 14;

[0120] D9, such as Figure 4As shown, steps D2 to D8 are continuously cycled until all prefabricated beams 13 and all prefabricated panels 14 are installed.

[0121] The assembly of the prefabricated panel 14 and the prefabricated beam 13 is as follows: Figure 5 shown.

[0122] In one or more embodiments, considering that there may be a large height difference between the shore 16 and the landing point of the support pier lower beam 12, it is impossible to support the support at the corresponding landing point by adjusting the height of the support itself. Therefore, in step A2, when the support leg leaves the shore, based on the height difference between the shore 16 and the landing point of the pier lower beam 12, a support gantry with a suitable height is installed at the bottom of the support leg, wherein the support gantry is used to increase the height of the support leg after it leaves the shore 16, can be regarded as a component of the support, and the support gantry can move on the track 9.

[0123] Specifically, the support gantry can be erected when the bracket just leaves the shore. At this time, the bracket is close to the shore 16, and the construction workers can erect the support gantry on the shore 16, which is convenient for construction and is less affected by waves.

[0124] In one or more embodiments, after completing the installation of all prefabricated beams 13 and all prefabricated panels 14 within the wharf range, the step of installing prefabricated parts of the approach bridge 15 by means of the hoisting trolley 1 may be further included.

[0125] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
