Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bridge construction, in particular to a hanging basket construction method and a hanging basket device for continuous beam pouring. BACKGROUND

[0002] As the core temporary support system of the cantilever pouring construction of the long-span prestressed bridge, the stability and construction efficiency of the structure of the hanging basket directly affect the overall construction efficiency and safety of the bridge. In the traditional construction, the front lower cross beam and the rear lower cross beam of the bottom basket need to be hoisted respectively first, and then the longitudinal beam of the bottom basket is hoisted after the two cross beams are in place. The assembly of the bottom basket system is completed through the welding operation of the longitudinal beam and the front and rear lower cross beams. However, the core processes such as cross beam hoisting, longitudinal beam butt joint and welding need to be completed in the air, which increases the amount of high-altitude operation and the safety risk. Moreover, the construction precision depends on the manual positioning and adjustment in the high-altitude operation, which is difficult to operate and difficult to control the error, and is prone to cause insufficient assembly precision of the bottom basket, thereby affecting the overall stress stability of the hanging basket.

[0003] In order to solve the drawbacks of the traditional piece-by-piece installation technology, an improved scheme of integral hoisting and dismounting of the bottom basket has appeared in the prior art. For example, the patent application CN120625499A discloses a method for integral dismounting of a rigid-frame bridge hanging basket formwork. Anchor bolts are embedded in the hanging basket, and a winch is anchored. The hanging basket anchoring system is loosened to separate the hanging basket bottom formwork from the concrete box girder. Four winches are arranged to cooperate with the fixed pulley. After the hanging basket bottom formwork is synchronously lifted for static load testing, the hanging basket bottom formwork is synchronously lowered to the ground. The winch is used to realize the integral hoisting and dismounting of the bottom basket system, thereby improving the dismounting efficiency.

[0004] However, the prior art lacks effective control of the stability of the integral hoisting in the process of integral hoisting of the bottom basket, and problems such as uneven stress and synchronization deviation are prone to occur. At the same time, the precise positioning in the integral installation process of the bottom basket still needs additional high-altitude adjustment operation. Therefore, the integral hoisting technology of the bottom basket of the existing hanging basket still has room for improvement in terms of stability control and installation positioning accuracy, and there is an urgent need for a construction technology scheme that can balance the hoisting stability and positioning accuracy.

DETAILED DESCRIPTION

[0058] In order to make the above objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the drawings. In the following description, a large number of specific details are set forth in order to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0059] With reference to Figure 1 and Figure 2 , the hanging basket device 10 for continuous beam in an embodiment of the present application, the hanging basket device 10 includes a hanging basket mechanism 100, a bottom basket mechanism 200 and a hanging mechanism 300, the hanging basket mechanism 100 is used to be installed on the continuous beam and can move on the continuous beam; the bottom basket mechanism 200 is arranged below the hanging basket mechanism 100; the hanging mechanism 300 is installed on the hanging basket mechanism 100, the hanging mechanism 300 includes a hanging rod 310 and a hanging jack 320, the hanging jack 320 is installed on the hanging basket mechanism 100, one end of the hanging rod 310 is connected to the hanging jack 320, the other end is connected to the bottom basket mechanism 200, the hanging jack 320 is used to adjust the movement of the bottom basket mechanism 200 driven by the hanging rod 310, so as to adjust the position of the bottom basket mechanism 200.

[0060] In an embodiment, the hanging basket mechanism 100 comprises a main truss 110, a front upper cross beam 120, a rear upper cross beam 130, and a walking anchoring assembly 140. The number of main trusses 110 is at least two, and each main truss 110 is arranged along the width direction of the continuous beam. The front upper cross beam 120 and the rear upper cross beam 130 are respectively arranged at the front top end and the middle of each main truss 110 to realize the connection of each main truss 110. The bottom of each main truss 110 is correspondingly provided with a walking anchoring assembly 140, and the walking anchoring assembly 140 realizes the forward movement and anchoring of the hanging basket mechanism 100.

[0061] In combination with Figure 3 and Figure 4 In an embodiment, the hanging mechanism 300 further comprises a locking mounting seat 330 and a locking inclined block 340. The suspension rod 310 is a rod member with a rectangular cross-section. A plurality of limiting protrusions 312 are arranged on the two opposite surfaces of the suspension rod 310, and each limiting protrusion 312 is arranged along the length direction of the suspension rod 310. The locking mounting seat 330 is formed with a locking hole 331, and the cross-sectional size of the locking hole 331 tends to decrease in the downward direction. The number of locking inclined blocks 340 is two, and the two locking inclined blocks 340 are arranged in the locking hole 331 and located on the two opposite sides of the suspension rod 310, respectively. The locking inclined block 340 can abut against the limiting protrusion 312. The hanging jack 320 is arranged on the hanging basket mechanism 100 and abuts against the locking mounting seat 330. The hanging jack 320 is used to drive the locking mounting seat 330 to move the suspension rod 310 in the vertical direction. Specifically, the surface of one end of the suspension rod 310 is provided with a limiting protrusion 312, and the one end of the suspension rod 310 is arranged in the locking hole 331, and the other end is connected to the bottom basket mechanism 200.

[0062] When the bottom basket mechanism 200 is hoisted, the suspension rod 310 not only bears the vertical tension, but also needs to resist the lateral shear force, such as asymmetric pouring of concrete, wind load, and slight swing of the bottom basket mechanism 200. Since the suspension rod 310 has a rectangular cross-section, the plate-shaped suspension rod 310 has good load bearing stability, controllable posture, and strong lateral and torsional resistance. At the same time, the face contact between the plate-shaped suspension rod 310 and the locking inclined block 340 can form a stable force system, the lateral displacement is small, and the shear slip is not easy to occur. When the force point is adjusted by the hanging jack 320, the eccentricity is also not easy to occur.

[0063] If the holes are opened on the suspender 310 to fix the position of the suspender 310 by means of the through-hole bolts, generally, in order to adapt to the bottom basket mechanism 200 of different heights, a plurality of through-holes arranged at intervals need to be opened on the suspender 310, the through-holes will cause the tensile capacity, lateral resistance and torsional resistance of the suspender 310 to decrease, which directly affects the stability and safety of the hoisting bottom basket mechanism 200 and the concrete construction. If the suspender 310 is set in a cylindrical shape, the lateral stability is poor, and once a small lateral force is applied, the suspender 310 is prone to lateral rotation. At the same time, the suspender 310 in a cylindrical shape is generally locked by means of threaded connection, and the threaded connection is prone to generate additional torque in the adjustment process, which causes the axis of the suspender 310 to deviate; when the plurality of hoisting points are synchronously adjusted, the deviation problem is amplified, which affects the stability of the hoisting of the bottom basket mechanism 200.

[0064] Specifically, the size of the cross section of the suspender 310 is 40mmx160mm, and the length of the suspender 310 is set according to the distance between the bottom basket mechanism 200 and the hanging basket mechanism 100. The thickness of the limiting protrusion 312 is 8mm-15mm, and the outer surface of the limiting protrusion 312 is a circular arc surface, the radius of the circular arc of the limiting protrusion 312 is 200mm-300mm, and the limiting protrusion 312 is integrally forged with the suspender 310, which is continuous in material and has no weld. At the same time, each limiting protrusion 312 on both sides of the suspender 310 is symmetrically arranged to make the suspender 310 bear force more evenly.

[0065] In an embodiment, the hoisting mechanism 300 further comprises a limiting assembly 350, a limiting hole is opened on the inner wall of the locking hole 331, and the limiting assembly 350 is arranged in the limiting hole. When the locking inclined block 340 moves downward and is pressed on the suspender 310, the limiting hole is located above the locking inclined block 340, and the limiting assembly 350 can extend above the locking inclined block 340 to prevent the locking inclined block 340 from loosening during vibration or adjustment movement, thereby improving the stability of the pressing and locking of the suspender 310.

[0066] In an embodiment, the hoisting mechanism 300 further comprises a guide assembly 360, and a guide hole 362 is formed in the guide assembly 360. The size of the cross section of the guide hole 362 matches the size of the cross section of the suspender 310. One suspender 310 is correspondingly provided with two hoisting jacks 320, and the guide assembly 360 is arranged between the two hoisting jacks 320, and the suspender 310 is arranged in the guide hole 362. Since the size of the cross section of the guide hole 362 matches the suspender 310, the suspender 310 can be rigidly wrapped and guided, which effectively limits the lateral swing of the suspender 310 during construction and effectively prevents the suspender 310 from being twisted when tension adjustment or load mutation occurs. Specifically, the length of the guide hole 362 is 1.5-3 times the width of the suspender 310, which can form long-distance linear guidance.

[0067] In an embodiment, the guide assembly 360 comprises a guide base and supporting pads, the guide base is formed with a guide hole 362 for the suspender to pass through, and the supporting pads are detachably arranged on the guide base, and the number or thickness of the supporting pads is arranged according to the distance between the guide base and the locking mounting base 330, so that the distance between the supporting pads and the locking mounting base 330 is 2-10 mm.

[0068] Referring to Figure 1 , Figure 5 and Figure 6 In an embodiment, the bottom basket mechanism 200 comprises a front lower cross beam 210, a rear lower cross beam 220 and a longitudinal beam 230, and the longitudinal beam 230 connects the front lower cross beam 210 and the rear lower cross beam 220.

[0069] In an embodiment, the hanging basket device 10 further comprises winches 400, and each winch 400 is connected with two suspender ropes 410; one end of the suspender rope 410 away from the winch 400 is connected to the bottom basket mechanism 200. In this embodiment, the front upper cross beam 120 and the rear upper cross beam 130 of each hanging basket mechanism 100 in two pouring directions are each provided with a fixed pulley 420, and two groups of winches 400 are arranged on the top surface of the No. 0 block along the pouring direction. Each winch 400 is connected with two suspender ropes 410, one of which is connected to the front lower cross beam 210 of the corresponding bottom basket mechanism 200 after passing through the fixed pulley 420 of the front upper cross beam 120 of the hanging basket mechanism 100 on the corresponding side of the winch 400, and the other is connected to the rear lower cross beam 220 of the bottom basket mechanism 200 on the other side after passing through the fixed pulley 420 of the rear upper cross beam 130 of the hanging basket mechanism 100 on the other side. The other suspender rope 410 of the other winch 400 is connected to the front lower cross beam 210 of the corresponding bottom basket mechanism 200 after passing through the fixed pulley 420 of the front upper cross beam 120 of the hanging basket mechanism 100 on the corresponding side of the winch 400, and the other is connected to the rear lower cross beam 220 of the bottom basket mechanism 200 on the other side after passing through the fixed pulley 420 of the rear upper cross beam 130 of the hanging basket mechanism 100 on the other side.

[0070] The two groups of winches 400 adopt a mode of single winch 400 corresponding to double hoisting ropes 410 and cross connection of the hoisting ropes 410. The cross-coupled connection mode makes the front and rear ends of the two-side bottom basket mechanisms 200 form a linkage relationship in force, avoiding the synchronization deviation caused by independent movement of the single-side bottom basket mechanism 200. Therefore, only the positions of the front lower cross beams 210 and the rear lower cross beams 220 of one side of the bottom basket mechanism 200 need to be controlled, and the positions of the other side of the bottom basket mechanism 200 can be controlled synchronously, without the need for additional synchronous control equipment, the operation logic is simple, the control error of multiple equipment cooperation is reduced, and the construction operation difficulty is reduced. The improvement of positioning accuracy and the reduction of adjustment frequency significantly reduce the amount of high-risk operations such as high-altitude attitude adjustment and hoisting rope 410 adjustment. At the same time, the layout of the cross hoisting ropes 410 enables the front lower cross beams 210 and the rear lower cross beams 220 of each bottom basket mechanism 200 to be subjected to symmetrical traction forces of the two groups of winches 400, and the traction angles of the hoisting ropes 410 are approximately similar, so that the forces during the hoisting process of the winches 400 and the bottom basket mechanisms 200 are more balanced and stable, avoiding the tilting, twisting or local deformation of the bottom basket mechanism 200 caused by excessive force on one side, and avoiding the excessive force on one side of the hanging basket mechanism 100, which causes uneven force on the No. 0 block. The symmetrical constraint of the cross hoisting ropes 410 makes the horizontal deviation of the bottom basket mechanism 200 controllable during the hoisting process, avoiding the positioning deviation caused by shaking and tilting. The two groups of winches 400 simultaneously drive the two bottom basket mechanisms 200 to hoist, without the need to hoist the single-side bottom basket mechanism 200 in sequence, and the hoisting time is shortened. The design of the hanging basket mechanism 100 for the two pouring directions of the No. 0 block, the arrangement of the cross hoisting ropes 410 and the fixed pulleys 420 match the symmetrical construction logic of the double-side cantilever pouring, so that the force on the entire No. 0 block is balanced. Through the layout of the two groups of winches 400 and the cross hoisting ropes 410, the technical pain points of synchronous control difficulty, unbalanced force, large positioning deviation and low construction efficiency in the overall hoisting of the existing double bottom basket mechanisms 200 are effectively solved.

[0071] If the two hoisting ropes 410 of one group of winches 400 are connected to the front lower cross beams 210 of the two bottom basket mechanisms 200, and the two hoisting ropes 410 of the other group of winches 400 are connected to the rear lower cross beams 220 of the two bottom basket mechanisms 200, it will cause a large difference in the lengths of the two hoisting ropes 410 corresponding to each winch 400, and the elastic elongation of the hoisting ropes 410 will be significantly different, which will easily cause the force imbalance phenomenon of long rope relaxation and short rope overload under load, resulting in large synchronization deviation of the two bottom basket mechanisms 200. At the same time, different winches 400 are subjected to different forces, which causes different forces applied to the No. 0 block, affecting the uniformity of the force.

[0072] Specifically, two fixed pulleys 420 are symmetrically installed at both ends of the front upper cross beam 120 and the rear upper cross beam 130 of each hanging basket mechanism 100. Each group of winches 400 includes two winches 400, and the two winches 400 in each group are arranged along the width direction of the top surface of the No. 0 block. The hoisting ropes 410 of the two winches 400 in each group are respectively connected to the two ends of the bottom basket mechanism 200. In this embodiment, the winches 400 are fixed on the No. 0 block by using pre-buried anchor bolts, the pulling resistance of the anchor bolts is greater than or equal to twice the maximum working tension of the winches 400, and after installation, the axis of the winch drum is calibrated to be parallel to the axis of the fixed pulley 420, with a deviation of within 5 mm. The fixed pulleys 420 are symmetrically installed at both ends of the front upper cross beam 120 and the rear upper cross beam 130 of each hanging basket mechanism 100, and are arranged along the width direction in cooperation with the two winches 400 in each group, so that each bottom basket mechanism 200 forms four traction points, and the stress of the bottom basket mechanism 200 during hoisting is more uniform. The two winches 400 in each group are synchronously controlled, the displacement of the two bottom basket mechanisms 200 in the width direction is synchronized, and the two winches 400 in each group respectively control the two ends of the bottom basket mechanism 200, so that the winding amount of each winch 400 can be independently adjusted to correct the positioning deviation of the bottom basket mechanism 200 in the width direction.

[0073] In an embodiment, as shown in Figure 6 , a guide wheel 430 is further arranged on the No. 0 block. The hoisting rope 410 passing through the fixed pulley 420 is connected to the winch 400 after passing through the guide wheel, so that each hoisting rope 410 can be connected to the winch 400 in a horizontal state.

[0074] In other embodiments, the number of winches 400 in each group can also be set according to the width of the bottom basket mechanism 200, that is, according to the size of the continuous beam in the width direction. If the width of the bottom basket mechanism 200 is large, the number of winches 400 in each group can be increased to three, so as to improve the stability of hoisting the bottom basket mechanism 200.

[0075] Please refer to Figure 1 , Figures 5 to 7 In an embodiment, the hanging basket construction method for continuous beam pouring can be applied to the hanging basket equipment 10 in any of the above embodiments. Specifically, the hanging basket construction method comprises:

[0076] Step S1: two hanging basket mechanisms 100 arranged in opposite directions are respectively installed on the No. 0 block of the continuous beam in two pouring directions.

[0077] Step S2: splice two bottom basket mechanisms 200, and install at least two winches 400 on the No. 0 block, and install fixed pulleys 420 on each hanging basket mechanism 100.

[0078] Specifically, the splicing of two bottom basket mechanisms 200 includes: leveling a site directly below the construction block section, and then placing the interval between the front lower crossbeam 210 and the rear lower crossbeam 220 on the site, and using sleepers to pad to form a splicing platform. A layer of steel plate with a thickness of about 1 cm is laid on the top of the splicing platform to reduce the friction between the crossbeams and the splicing platform, so as to facilitate the fine adjustment of the positions of the front lower crossbeam 210 and the rear lower crossbeam 220. The rear lower crossbeam 220 is first hoisted to the splicing platform by using hoisting equipment, and then placed in position, and the center line is placed, and then the front lower crossbeam 210 is hoisted and placed according to the position of the rear lower crossbeam 220. Then the bottom basket longitudinal beams 230 are installed, the longitudinal beams 230 at both ends and in the middle are placed first, and the distance is checked by pulling the diagonal lines, and the error is required to be within ±5 mm. After meeting the requirements, other longitudinal beams 230 are placed, and the longitudinal beams 230 and the front and rear lower crossbeams are welded. When welding, spot welding is performed first and welding is performed at intervals, and asymmetric welding is strictly prohibited. Further, counterweights are arranged at both ends of the front lower crossbeam 210 and the rear lower crossbeam 220 to reduce the crossbeam deformation caused by temperature stress.

[0079] Specifically, a fixed pulley 420 is arranged on each hanging basket mechanism 100, including: a fixed pulley 420 is arranged on the front upper crossbeam 120 and the rear upper crossbeam 130 of each hanging basket mechanism 100. Further, at least two fixed pulleys 420 are symmetrically arranged at both ends of the front upper crossbeam 120 and the rear upper crossbeam 130 of each hanging basket mechanism 100; the axis of the fixed pulley 420 is aligned with the center line of the hoisting point of the bottom basket mechanism 200, or the deviation is less than or equal to 10 mm, and the fixed pulley 420 is fixed to prevent displacement during hoisting.

[0080] Specifically, at least two winches 400 are arranged on the No. 0 block, including: two groups of winches 400 are arranged on the top surface of the No. 0 block along the pouring direction. Further, two groups of winches 400 are arranged on the top surface of the No. 0 block along the pouring direction, each group containing two winches 400, and the two winches 400 in each group are arranged along the width direction of the No. 0 block, and the interval of the two winches 400 in each group matches the hoisting points of the bottom basket mechanism 200 in the width direction, and respectively corresponds to both ends of the bottom basket mechanism 200. The interval of the two winches 400 along the width direction of the No. 0 block and the deviation of the hoisting points of the bottom basket mechanism 200 in the width direction are less than or equal to 10 cm. The winches 400 are fixed by using pre-buried anchor bolts, and the anchor bolts have a pulling resistance greater than or equal to 2 times the maximum working tension of the winches 400 after installation.

[0081] Step S3: The hoisting ropes 410 of the at least two winches 400 are respectively wound around the fixed pulleys 420 to connect the two bottom basket mechanisms 200.

[0082] Specifically, step S31: each winch 400 is connected with two ropes 410, one of which is connected to the front lower crossbeam 210 of the corresponding side bottom basket mechanism 200 after passing through the fixed pulley 420 of the front upper crossbeam 120 of the corresponding side hanging basket mechanism 100, and the other is connected to the rear lower crossbeam 220 of the other side bottom basket mechanism 200 after passing through the fixed pulley 420 of the rear upper crossbeam 130 of the other side hanging basket mechanism 100.

[0083] Step S32: the other group of winches 400 is connected with two ropes 410, one of which is connected to the front lower crossbeam 210 of the corresponding side bottom basket mechanism 200 after passing through the fixed pulley 420 of the front upper crossbeam 120 of the corresponding side hanging basket mechanism 100, and the other is connected to the rear lower crossbeam 220 of the other side bottom basket mechanism 200 after passing through the fixed pulley 420 of the rear upper crossbeam 130 of the other side hanging basket mechanism 100.

[0084] In the present embodiment, the two groups of winches 400 are respectively the front group and the rear group. For the first rope 410 of the left winch 400 in the front group: one end is fixed to the drum of the winch 400, passes through and then is connected to the left end of the front lower crossbeam 210 of the front side bottom basket mechanism 200 after passing through the fixed pulley 420 of the front upper crossbeam 120 of the front side hanging basket mechanism 100; the second rope 410: one end is fixed to the drum of the same winch 400, passes through and then is connected to the right end of the rear lower crossbeam 220 of the rear side bottom basket mechanism 200 after passing through the fixed pulley 420 of the rear upper crossbeam 130 of the rear side hanging basket mechanism 100. For the first rope 410 of the right winch 400 in the front group: one end is fixed to the drum of the winch 400, passes through and then is connected to the right end of the front lower crossbeam 210 of the front side bottom basket mechanism 200 after passing through the fixed pulley 420 of the front upper crossbeam 120 of the front side hanging basket mechanism 100; the second rope 410: one end is fixed to the drum of the same winch 400, passes through and then is connected to the left end of the rear lower crossbeam 220 of the rear side bottom basket mechanism 200 after passing through the fixed pulley 420 of the rear upper crossbeam 130 of the rear side hanging basket mechanism 100. The arrangement of the two ropes 410 of the two winches 400 in the rear group is symmetrical to that of the winches 400 in the front group. In the present embodiment, the left and right ends are the ends of the crossbeams, and the left and right sides are the sides opposite to the ends of the crossbeams. The left and right positions are respectively the left and right when facing the corresponding hanging basket mechanism.

[0085] Further, after step S3, it further comprises: driving the winch 400 to pre-tension each hoisting rope 410, so that the pre-tension force is 5%-15% of the self-weight of the bottom basket mechanism 200, checking the uniformity of the force borne by each hoisting rope 410, if the deviation of the two hoisting ropes 410 with the largest and smallest force borne is greater than or equal to the preset deviation, then adjusting the length of each hoisting rope 410 according to the force borne by each hoisting rope 410, until the force borne by each hoisting rope 410 under the pre-tension driving of the winch 400 has a deviation less than the preset deviation, so as to ensure the uniformity of the force borne by each hoisting rope 410.

[0086] Step S4: controlling each winch 400 to synchronously hoist the two bottom basket mechanisms 200 to a preset trial hoisting height, keeping for a preset trial hoisting time, and then continuing to control each winch 400 to synchronously hoist the two bottom basket mechanisms 200 to a coarse positioning position.

[0087] Specifically, the control of each winch 400 to synchronously hoist the two bottom basket mechanisms 200 comprises:

[0088] Step S41: obtaining whether the hoisting height deviation of the front lower cross beam 210 and the rear lower cross beam 220 of a bottom basket mechanism 200 is within a preset range; if not, adjusting the operation of the winch 400 connected with the front lower cross beam 210 of the bottom basket mechanism 200 or the winch 400 connected with the rear lower cross beam 220 of the bottom basket mechanism 200, so that the hoisting height deviation of the front lower cross beam 210 and the rear lower cross beam 220 of the bottom basket mechanism 200 is within the preset range; and ensuring that the bottom basket mechanism 200 is roughly aligned with the pouring direction axis.

[0089] Step S42: obtaining whether the levelness of a bottom basket mechanism 200 in the width direction of the No. 0 block is within a preset range; if not, adjusting the synchronous operation of the two winches 400 in the relative position to adjust the levelness of the bottom basket mechanism 200 in the width direction.

[0090] During the lifting of the bottom basket mechanism 200, due to the uneven force borne by the hoisting ropes 410, the slight deviation of the winch 400 synchronization, etc., the front lower cross beam 210 and the rear lower cross beam 220 of a single bottom basket mechanism 200 may have a height difference. If the front lower cross beam 210 is higher than the rear lower cross beam 220, the winch 400 connected with the front lower cross beam 210 can be slowed down or paused, while the winch 400 connected with the rear lower cross beam 220 is kept normal operation or slightly reeled, until the height deviation of the front and rear lower cross beams is reduced to a preset range, so as to ensure the posture of the bottom basket mechanism 200 during lifting, and reduce the adjustment amount for the axis calibration in the subsequent coarse positioning and fine positioning stages. Due to the cross arrangement of the hoisting ropes 410, only one of the bottom basket mechanisms 200 needs to be detected and adjusted during hoisting, so that the two bottom basket mechanisms 200 can be kept synchronous at the same time.

[0091] Specifically, start four winches 400, control the winches 400 to uniformly wind the hoisting ropes 410, and hoist the two bottom basket mechanisms 200 to a preset trial hoisting height synchronously; for example, the preset trial hoisting height can be a position 10 cm-20 cm away from the ground or an initial position. Keep the trial hoisting state for a preset trial hoisting time; for example, the preset trial hoisting time can be 5-20 minutes, during which the maximum deviation of the tension of each hoisting rope 410 is monitored, and the deviation of the levelness of the bottom basket mechanism 200 is monitored. If the maximum deviation of the tension of the hoisting rope 410 is less than a preset deviation, and the deviation of the levelness of the bottom basket mechanism 200 is less than a preset value, the hoisting of the bottom basket mechanism 200 can continue. If the maximum deviation of the tension of the hoisting rope 410 is greater than or equal to the preset deviation, or the deviation of the levelness of the bottom basket mechanism 200 is greater than or equal to the preset value, the operation is immediately stopped, and the length of the hoisting rope 410 and the synchronization parameters of the winches 400 are adjusted before the trial hoisting is restarted until the standard is met.

[0092] Specifically, after the trial hoisting is qualified, the four winches 400 are controlled to synchronously hoist at a speed of 0.1-0.5 m / min, and the two bottom basket mechanisms 200 are hoisted to a rough positioning position 20 cm-60 cm away from the bottom surface of the box girder, such as a rough positioning position at 50 cm, and then the hoisting is stopped. At this time, the position and attitude of the bottom basket mechanism 200 can be adjusted through the winches 400 according to the current position of the bottom basket mechanism 200.

[0093] Step S5: Install the hanging mechanism 300 on the hanging basket mechanism 100, so that one end of the boom 310 of the hanging mechanism 300 is connected to the hanging jack 320, and the other end is connected to the bottom basket mechanism 200. Specifically, each bottom basket mechanism 200 is configured with 4 booms 310, one at each end of the front and rear lower cross beams, one end of the boom 310 is connected to the lifting lug of the bottom basket mechanism 200, and the other end is connected to the hanging jack 320, ensuring that the perpendicularity deviation of the boom 310 is ≤1%, and there is no bending, and then the locking of the boom 310 is realized through the locking inclined block 340 in the locking mounting seat 330.

[0094] Step S6: disconnect the hoisting ropes 410 connected to the bottom basket mechanism 200, and adjust the length of the boom 310 through the hanging jack 320 to adjust the bottom basket mechanism 200 to the continuous beam pouring position. Specifically, slowly loosen the hoisting ropes 410 of the winches 400, while observing the change in the tension of the boom 310, to ensure that the force of the bottom basket mechanism 200 gradually transfers from the hoisting ropes 410 to the boom 310, until the hoisting ropes 410 are completely unloaded, at which time the boom 310 completely bears the load of the bottom basket mechanism 200. After confirming that the force transfer is complete, all hoisting ropes 410 of the winches 400 are removed.

[0095] In an embodiment, the step S4 further includes, after the step S4:

[0096] Safety wire ropes are installed at four corner points of the bottom basket mechanism 200, with one end of the safety wire ropes connected to the bottom basket mechanism 200 and the other end connected to the hanging basket mechanism 100.

[0097] Specifically, safety wire ropes are installed at four corner points of the bottom basket mechanism 200, and the safety wire ropes can be composed of two safety ropes with a diameter of 20-25 mm. In this embodiment, the safety wire ropes are selected considering the most unfavorable working condition, and the weight of the bottom basket mechanism 200 is entirely borne by the safety wire ropes. Taking the weight of the bottom basket mechanism 200 as 47.22 t as an example, the tension borne by a section of safety rope of a single lifting point is F = 47.22 * 10 / 4 / 4 = 29.51 KN. Two safety ropes are used for each lifting point, and the strength of a single safety rope is 1400 N / mm 2 The allowable tension of the safety wire rope is:

[0098] wherein α is an unbalanced coefficient, which is taken as 0.85 herein; Fg is the total breaking tension of the safety wire rope, which is taken as 245.5 KN herein; and K is a safety coefficient, which is taken as 6 herein. The safety wire rope formed by two safety ropes with a diameter of 20-25 mm can meet the requirements.

[0099] In an embodiment, the step S4 further includes: installing an inner formwork assembly and an outer formwork assembly on the bottom basket mechanism 200.

[0100] In an embodiment, the hanging basket construction method further includes:

[0101] When the pouring of the closure segment of the continuous beam is completed and the strength reaches the design strength, the inner formwork assembly on the bottom basket mechanism 200 is removed;

[0102] The hanging jack 320 is adjusted to lower the suspender 310, so that the outer formwork assembly on the bottom basket mechanism 200 is separated from the surface of the continuous beam concrete;

[0103] After the bottom basket mechanism 200 is retreated to the No. 0 block under the control of the hanging basket mechanism 100, the hanging basket mechanism 100 is locked;

[0104] After the hoisting ropes 410 of each winch 400 on the No. 0 block are respectively wound around the fixed pulleys 420 on the corresponding hanging basket mechanism 100 to connect two bottom basket mechanisms 200, and the hoisting ropes 410 are synchronously wound to make each hoisting rope 410 bear an even force, the suspender 310 is slowly released after the force borne by the bottom basket mechanism 200 is completely transferred to the hoisting ropes 410, and then the suspender 310 is removed;

[0105] The two bottom basket mechanisms 200 are synchronously lowered by starting the respective winches 400, and if the bottom basket mechanisms 200 are tilted during the lowering process, the attitude of the bottom basket mechanisms 200 is adjusted by adjusting the corresponding winches 400.

[0106] When the bottom basket mechanisms 200 are lowered to the ground, the lifting ropes 410 of the winches 400 are released.

[0107] During the dismantling stage of the bottom basket mechanisms 200, the hanging basket mechanism 100 drives the bottom basket mechanisms 200 to retreat from the 0# block or the adjacent stable beam section, the strong bearing capacity of the 0# block is used as the reference for the dismantling operation, and the cantilever end load risk is reduced. The cross-type lifting rope 410 layout in the hoisting stage is combined with the double-winch 400 linkage system, without the need for additional dedicated equipment for dismantling, reducing the workload of equipment transportation, installation and debugging. Through the steps of connecting by the lifting rope 410 → uniform stress → load transfer → dismantling the suspender 310, the stress of the bottom basket mechanism 200 is smoothly switched from the suspender 310 bearing to the lifting rope 410 bearing. The dismantling process corresponds to the hoisting process, and the standardized process can effectively improve the dismantling efficiency of the bottom basket mechanism 200. The winches 400 synchronously lower the bottom basket mechanisms 200, and if the tilt is not corrected in time, it is easy to collide with the side of the box girder or cause the bottom basket mechanism 200 to deform. The attitude is corrected in real time by adjusting the corresponding winches 400 to avoid collision or overturning.

[0108] If the bottom basket mechanisms 200 are directly operated at the cantilever end during dismantling, the cantilever section will bear additional load, which may cause the hanging basket mechanism 100 to lose stability or damage the continuous beam structure. Moreover, the operation space around the 0# block is more open, which is convenient for operators to operate and equipment to be laid out, further reducing the safety risks of high-altitude falling and object impact.

[0109] The above-mentioned hanging basket construction method for continuous beam pouring controls the respective winches 400 to synchronously lift the two bottom basket mechanisms 200, and through the linkage control of at least two winches 400, the synchronous lifting and positioning of the two pouring direction bottom basket mechanisms 200 are realized, and the hoisting time is shortened. At the same time, the double hanging basket mechanisms 100 are arranged opposite to each other in the two pouring directions of the 0# block, and the two bottom basket mechanisms 200 are synchronously hoisted, forming a symmetrical stress structure, which avoids the overloading of the single hanging basket mechanism at the 0# block pre-buried point caused by single-side hoisting, and further avoids the uneven stress of the 0# block. The hoisting combination of the winch 400 and the fixed pulley 420 reduces the cumbersome procedures in traditional separate piece hoisting, reduces the labor and equipment investment cost, and reduces the temporary adjustment time in the hoisting process.

[0110] At the pre-set test hoisting height of the bottom basket mechanism 200 from the ground, the uniformity of the lifting rope 410 stress, the synchronicity of the winch 400, the attitude of the bottom basket mechanism 200, the stability of the anchoring system, etc. can be statically detected, and if deviations or problems are found, they can be quickly adjusted at low altitude, avoiding rework caused by problems found after the bottom basket mechanism 200 is lifted.

[0111] The bottom basket is sent to the rough positioning position by the winch 400 in synchronization, avoiding the large deviation caused by directly lifting the bottom basket mechanism 200 to the position. The boom 310 and the hanging jack 320 of the hanging mechanism 300 are connected to the bottom basket mechanism 200. After the lifting rope 410 is removed, the position of the bottom basket mechanism 200 is adjusted, the residual deviation in the rough positioning stage can be accurately corrected, and the bottom basket mechanism 200 is finally positioned to the continuous beam pouring position, meeting the positioning requirements of the continuous beam pouring formwork.
