Description

Technical Field

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

[0002] At present, prefabricated construction, as a new trend, has gradually been applied in the field of wharf construction. Among them, for the construction of prefabricated wharfs, prefabricated components (such as prefabricated beams and prefabricated panels) can be hoisted between the pre-arranged lower beams of the wharf, thereby completing the erection of the prefabricated wharf.

[0003] The wharf is usually tens of meters away from the shore and connected by an approach bridge. At present, prefabricated components are mostly transported to the corresponding position within the wharf range by floating cranes for installation. The floating crane will rise and fall and sway with the waves, which may easily cause the lifted prefabricated components to collide with other structures on the construction site, or cause the prefabricated components that have been lowered but not yet separated from the lifting device to be suspended again. Therefore, the current method of suspending prefabricated components is greatly affected by sea conditions, the installation accuracy of prefabricated components is poor, and it is impossible to ensure that construction can be carried out at any time, which affects the construction efficiency and safety of wharf erection.

[0063] Example 1

[0064] A wharf is arranged on the shore 16, wherein the length of the wharf is several hundred meters, and the length direction of the wharf (hereinafter referred to as the wharf direction) is roughly parallel to the direction of the coast, wherein a plurality of wharf lower beams 12 are arranged in advance at intervals along the wharf direction in the wharf construction range (hereinafter referred to as the wharf range), and the length direction of the wharf lower beams 12 is roughly perpendicular to the wharf direction, and the distance between two adjacent wharf lower beams 12 is one span. The wharf lower beams 12 can be built from the shore 16 to the wharf range, so they will not be affected or excessively affected by sea conditions.

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

[0066] This embodiment provides a method for erecting an assembled high-pile dock, using a high-pile dock beam and slab erection integrated device. Figure 1 As shown, it includes a crossbeam 4, 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 (lateral direction) of the cross beam 4, wherein the longitudinal beam 2 can be moved laterally 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 rolls 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 nearly 3 times the width of each support leg along the longitudinal direction, so that the hoisting trolley 1 can at least move on the longitudinal beam 2 to both sides of all supports along 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 legs and adjust the length of the legs 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, and at the same time, the reverse roller device 10 serves as a driving mechanism, and the reverse roller device 10 is rotated 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 contact 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 the equipment on the shore 16, which can be set up by transportation or on-site assembly;

[0073] A2, taking the lower cross beam 12 of the wharf as the foothold, the equipment is driven by the plurality of legs to move from the shore 16 toward the wharf range until the front end of the cross beam 4 in the equipment moves to the wharf range and the rear end of the cross beam 4 is still located at the shore 16, so that the hoisting trolley 1 can hoist the prefabricated parts from the shore 16 to the wharf range for installation in the transverse direction;

[0074] A3. The track 9 is laid out along the length direction of the wharf by the hoisting trolley 1, so that the bottom of the outrigger can drive the entire equipment to move along the length direction of the wharf, and the prefabricated parts are hoisted from the shore 16 to the wharf range for installation by the hoisting trolley 1 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 range between the shore 16 and the dock 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 the 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 leg by the lifting trolley 1, so that the entire equipment can be moved along the length direction of the dock later, so that the lifting trolley 1 can lift prefabricated parts in the entire dock range.

[0076] The whole 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 equipment is lower, thereby improving the construction efficiency and safety of 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 cross beam 12 of the dock as a foothold and driving the device forward by a 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 moves forward along the length direction of the crossbeam 4 with the remaining legs on the two movable legs;

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

[0081] B3, the remaining legs and the other movable leg support the crossbeam 4, one of the movable legs is shortened and suspended in the air, and one of the movable legs moves along the length direction of the crossbeam 4 under the crossbeam 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 foothold of the support legs for supporting the cross beam 4 may be the cross beam 12 under the wharf or the shore 16 according to the location.

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

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

[0086] Based on this, Figure 2 As shown, in step A2, the method of using the lower cross 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, 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 cross beam 4, the front legs 6 are shortened and suspended, and the front legs 6 move forward along the length direction of the cross beam 4 under the cross beam 4;

[0089] B3, the front legs 6 and the front legs 6 support the crossbeam 4, the middle legs 7 are shortened and suspended, 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 required position, all legs support the beam 4 at the same time.

[0091] Among them, considering that in the process of hoisting the prefabricated parts to the wharf range for installation, the hoisting trolley 1 and the longitudinal beam 2 need to be moved to the corresponding position of the cross beam 4 along the length direction, at this 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 wharf range farthest from the shore 16; the middle legs 7 can be moved to the side of the wharf range closest to the shore 16, or the middle legs 7 can be moved between the wharf range and the shore 16. At this time, the front legs 6 and the middle legs 7 are respectively located on both sides of the wharf range, ensuring the support performance of the front legs and the middle legs 7 for the hoisting trolley 1 in the process of installing prefabricated parts in the wharf range.

[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 suspended beam section from the midpoint to the front end of the beam 4 along the length direction is temporarily supported by the front support member 5.

[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 support of the beam 4 during the subsequent 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 other functional components.

[0096] In order to realize the movement of the entire equipment 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 of the legs, 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, and 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 produce 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, among which two segments are shown in the figure.

[0098] When the equipment advances to the corresponding position and supports the crossbeam 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 wharf.

[0099] In step A3, the method of laying the track 9 along the length direction of the wharf by the lifting trolley 1 so that the bottom of the leg 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 the supports drive the entire device to move on the spliced ​​rails 9, so that the supports move to the top of the other rails 9. At this time, the other rails 9 participate in supporting the supports, and the part of the rails 9 that was previously at the bottom of the supports is exposed. At this time, the part of the rails 9 exposed to the outside does not support the supports and can be disassembled;

[0102] C3, using the lifting trolley 1, 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, looping steps C2-C3, so that the entire device moves along the length direction of the dock.

[0104] Through this method, the entire equipment can be moved along the length direction of the wharf. The whole process fully utilizes the lifting function of the lifting 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 cyclically laid, and there is no need to use too many tracks 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 lower beams 12 of adjacent wharves, by disassembling the track 9, it is possible to avoid obstruction to the operation of the corresponding prefabricated parts when the track 9 is erected on the lower beams 12 of two wharves.

[0105] In order to complete the installation of the prefabricated parts, in one or more embodiments, in step A3, the method of lifting the prefabricated parts from the shore 16 to the wharf range for installation by the lifting trolley 1 includes:

[0106] D1. Move the equipment to the first span (i.e., the position of the two adjacent lower cross beams 12 of the dock at the edge), and hoist a plurality of prefabricated parts from the shore 16 to the position between the front legs 6 and the middle legs 7 for installation by means of the hoisting trolley 1. 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 hoist the prefabricated parts to the position of the front legs 6 or the middle legs 7 for installation;

[0107] D2. Move the equipment along the length direction of the wharf by one span, 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. The prefabricated parts are hoisted to the area blocked by the front legs 6 and the middle legs 7 in the previous step by the hoisting trolley 1 for installation. During the installation process, the hoisting trolley 1 and the prefabricated parts are on the side of the front legs 6 or the middle legs 7. Since the area required for installation in this step is small and the time required is short, the equipment will not be subjected to lateral loads for a long time.

[0108] D3, using the lifting trolley 1 to hoist multiple prefabricated parts from the shore 16 to between the front supporting leg 6 and the middle supporting 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 one cycle.

[0110] Among them, when the prefabricated parts include prefabricated beams 13 and prefabricated panels 14, the installed prefabricated beams 13 need to be cast into one piece with the adjacent lower cross beams 12 of the dock, 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 range for installation by the lifting trolley 1 includes:

[0112] D1. Move the equipment to the first span, and use the hoisting trolley 1 to hoist a plurality of precast beams 13 from the shore 16 to between the front outrigger 6 and the middle outrigger 7 for arrangement, and cast the arranged precast beams 13 and the adjacent lower cross beams 12 of the wharf into one body, thereby installing the precast beams 13;

[0113] D2, move the equipment along the length direction of the wharf by one span, and use the hoisting trolley 1 to hoist the precast beam 13 to the area blocked by the front legs 6 and the middle legs 7 in the previous step for arrangement, and cast the arranged precast beam 13 and the adjacent lower cross beam 12 of the wharf into one body, so as to realize the installation of the precast beam 13;

[0114] D3, using the hoisting trolley 1 to hoist a plurality of precast beams 13 from the shore 16 to between the front outrigger 6 and the middle outrigger 7 for arrangement, and casting the arranged precast beams 13 and the adjacent lower cross beams 12 of the wharf into one body, thereby installing the precast beams 13;

[0115] D4, looping steps D2-D3;

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

[0117] D6, move the equipment along the length direction of the wharf by one span, and hoist the prefabricated panel 14 by the hoisting trolley 1 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, using the lifting trolley 1 to hoist a plurality of prefabricated panels 14 from the shore 16 to the prefabricated beam 13 between the front supporting leg 6 and the middle supporting leg 7 for installation;

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

[0120] D9, such as Figure 4As shown, steps D2-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 footing point of the lower crossbeam 12 of the support pier, it is impossible to support the support at the corresponding footing 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 footing point of the lower crossbeam 12 of the pier, 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 support just leaves the shore. At this time, the support 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 the installation of all prefabricated beams 13 and all prefabricated panels 14 within the wharf is completed, 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 protection scope of the present invention.
