Description

Technical Field

[0001] The present application relates to the technical field of concrete retaining wall casting, and in particular to a guide rail type slipform system and a construction method for retaining wall casting. Background Art

[0002] Against the background of rapid social and economic development, the transportation industry is developing at an increasingly rapid pace, the number and scale of construction projects are continuously expanding, vertical retaining wall structures are widely used in river shipping projects, and the volume and scale of vertical bank protection structures are also increasing.

[0003] The large volume of cast-in-place concrete retaining walls also increases the difficulty of cast-in-place concrete construction, among which the greatest impact is on the installation and dismantling efficiency of the large-volume concrete retaining wall formwork system.

[0004] At present, the commonly used cast-in-place formwork installation and removal construction process is mostly a layered and segmented construction of combined steel formwork + lifting equipment (crawler crane), but this process has defects such as frequent transportation and cross-construction in the steel formwork field, which greatly limits the construction efficiency of this process. Therefore, it is necessary to innovate the formwork system of large-volume cast-in-place retaining walls. Summary of the invention

[0005] In order to improve the construction efficiency of cast-in-place concrete retaining walls, the present application provides a guide rail slipform system and a construction method for retaining wall casting.

[0006] The present application discloses a guide rail type sliding form system for retaining wall casting, which adopts the following technical solution:

[0007] A guide rail slipform system for retaining wall casting, comprising a template group, a hoisting mechanism for hoisting the template group and a walking mechanism for driving the hoisting mechanism to move along the direction of concrete retaining wall casting, the template group comprising two steel templates facing each other, a plug-in plate being fixed on the side of the two steel templates away from each other, and a plurality of locking mechanisms for locking the corresponding plug-in plates on the ground are arranged on the ground for retaining wall casting.

[0008] By adopting the above technical solution, when it is necessary to cast the retaining wall, the two steel templates are first hoisted by the hoisting mechanism, and the walking mechanism drives the hoisting mechanism so that the two steel templates can move along the casting direction of the concrete retaining wall, so that the two steel templates can be quickly moved to the construction position. At this time, the steel template is hoisted by the hoisting mechanism so that the lower end of the steel template is in contact with the ground. During this process, the construction personnel cooperate to align the plug-in plate with the plug-in interface so that the locking mechanism quickly limits and locks the plug-in plate, so that the steel template can be quickly positioned and fixed. At this time, the concrete retaining wall can be quickly constructed, which greatly saves the construction period and improves the construction efficiency.

[0009] Optionally, the lifting mechanism includes legs, a load-bearing beam and a suspension assembly, wherein a plurality of legs are provided, each of the legs is fixedly mounted under the load-bearing beam and is used to support the load-bearing beam, and the suspension assembly is mounted on the load-bearing beam and is used to suspend the steel formwork.

[0010] By adopting the above technical solution, the legs are supported on the ground, and the suspension assembly is installed on the load-bearing beam. When the steel formwork needs to be hoisted, the steel formwork can be quickly hoisted through the suspension assembly.

[0011] Optionally, a plurality of diagonal braces are provided between each of the legs for reinforcing the legs.

[0012] By adopting the above technical solution, the diagonal brace can reinforce the structural strength of the support leg, making the suspension of the suspension assembly more stable and safe.

[0014] By adopting the above technical solution, after pouring one section of retaining wall, it is necessary to construct the next section of retaining wall. At this time, a pulling device is used to pull the supporting legs so that the sliding wheels at the bottom of the supporting legs slide on the steel rails, thereby quickly adjusting the position of the steel formwork.

[0015] Optionally, the locking mechanism includes a hollow mounting seat and a pre-positioning component, a linkage component and an unlocking component arranged in the mounting seat, the mounting seat is fixed on the ground, and a plug interface is opened on the top, and the pre-positioning component, the linkage component and the unlocking component are each provided with two groups, and are symmetrically arranged on both sides of the plug interface;

[0016] The pre-positioning component is used to guide and pre-clamp the plug-in at the end of the plug-in board. When the plug-in board is plugged into the plug-in port, the plug-in board drives the corresponding pre-positioning component to clamp and fix the board surface of the plug-in board through two groups of linkage components. The unlocking component is used to unlock the clamping of the plug-in board by the pre-positioning component.

[0017] By adopting the above technical solution, when the end of the plug-in board is inserted into the mounting seat from the plug-in interface on the mounting seat, the pre-positioning component in the mounting seat can guide and pre-clamp the plug-in board, and when the plug-in board continues to be plugged into the mounting seat, the end of the plug-in board will drive the linkage component to move, and the linkage component will drive the pre-positioning component to clamp and fix the board surface of the plug-in board. At this time, the pre-positioning component limits and locks the plug-in board, so that the steel template can be quickly limited and fixed.

[0018] Optionally, the pre-positioning component includes a telescopic rod, a positioning ball, a push piece and a connector. The telescopic rod is slidably installed in the mounting seat and is telescopic and retractable in the direction of the plug interface.

The connector is arranged at the fixed end of the telescopic rod. A partition is fixedly installed in the mounting seat. The mounting seat and the partition are arranged to form a channel. A plug hole is opened on the partition. When the end of the connector is opposite to the plug hole, the connector partially passes through the plug hole and extends into the channel. The unlocking component is used to make the connector pass through the plug hole and extend out of the channel.

[0019] By adopting the above technical solution, when the plug board enters the mounting seat, the plug board will pass between the two positioning balls. Under the push of the push piece, the telescopic rod will drive the two positioning balls to elastically abut against the board surface of the plug board, thereby pre-clamping the plug board.

[0020] Optionally, the linkage assembly includes a guide wheel, a rack and a push block, the guide wheel is rotatably mounted in the mounting seat and is located on a side of the positioning ball away from the plug interface, and the spacing between the two guide wheel surfaces in the two groups of the linkage assembly is the same as the thickness of the plug board;

[0021] An annular groove is provided on the outer peripheral wall of the guide wheel in the circumferential direction, and the bottom wall of the groove is provided with a tooth surface. The rack is slidably installed in the mounting seat and meshes with the tooth surface of the bottom wall of the groove. The push block is fixedly installed on one end of the rack, and one side of the push block is provided with a wedge-shaped inclined surface. The fixed end of the telescopic rod is in contact with the wedge-shaped inclined surface of the push block. When the rack moves toward the direction of the telescopic rod, the wedge-shaped inclined surface of the push block can drive the telescopic rod to move in the direction close to the plug interface.

[0022] By adopting the above technical solution, when the plug-in board continues to be plugged into the mounting seat, the plug-in board will drive the guide wheel to rotate, and the guide wheel will drive the rack to move, and the rack will drive the push block to move. At this time, the wedge-shaped slope of the push block will push the fixed end of the telescopic rod. When the telescopic end and the fixed end of the telescopic rod reach the maximum compression stroke, the positioning ball will rigidly abut against the board surface of the plug-in board. At the same time, the plug-in piece will pass through the plug-in hole and be plugged into the channel, so that the fixed end and the telescopic end of the telescopic rod are always kept at the maximum compression stroke, so that the two positioning balls can stably abut and fix the plug-in board, thereby quickly positioning and fixing the two steel templates.

[0023] Optionally, a pulling member for resetting the rack is provided at the end of the rack away from the push block.

[0024] By adopting the above technical solution, the pulling member can pull the end of the rack, so that the rack drives the push block to have a tendency to reset, which is convenient for the subsequent cooperation with the plug-in board to achieve separation from the mounting seat.

[0025] Optionally, the unlocking assembly includes a pull rod and a pull handle arranged at one end of the pull rod, the pull handle is located outside the mounting seat, the pull rod is slidably installed in the channel, and partially extends out of the mounting seat from the end of the channel, an arc groove is opened on the outer peripheral wall of the pull rod, and the end of the connector can pass through the plug hole and extend into the arc groove.

[0026] By adopting the above technical solution, after pouring a section of retaining wall, it is necessary to move the position of the steel formwork. At this time, it is necessary to first take the plug-in plate out of the mounting seat. At this time, first pull the two handles to a position away from the mounting seat, so that the two handles drive the corresponding pull rods to move in the channel. At this time, the arc groove on the pull rod will drive the end of the connector to extend out of the channel from the plug hole. At this time, the plug-in plate can be locked, and the suspension assembly can be used to lift the steel formwork, so as to facilitate the pouring of the next section of the retaining wall.

DETAILED DESCRIPTION

[0044] The following is combined with Figure 1-3 , further details of this application are given.

[0045] An embodiment of the present application discloses a guide rail sliding formwork system for retaining wall casting.

[0046] A rail-type slipform system for retaining wall casting, referring to Figure 1 , including a formwork group, a hoisting mechanism 1 for hoisting the formwork group, and a walking mechanism 2 for driving the hoisting mechanism 1 to move along the direction of pouring the concrete retaining wall.

[0047] The formwork group includes two opposite steel formworks 3, one steel formwork 3 is hoisted vertically to the ground, and the other steel formwork 3 is hoisted obliquely to the ground, and the inclination angle of this steel formwork 3 is an acute angle to the ground. The specific angle can be determined according to the inclination of the retaining wall actually cast.

[0048] A plug-in plate 31 is fixed on the side of the two steel formworks 3 that are away from each other. A plurality of locking mechanisms 4 for locking the corresponding plug-in plates 31 to the ground are arranged on the ground along the direction of casting the retaining wall. The locking mechanism can quickly lock the steel formworks 3 to the ground, thereby facilitating and quickly positioning and installing the steel formworks 3, reducing the time spent on adjusting the position of the steel formworks 3 and improving construction efficiency.

[0049] Specifically, refer to Figure 1 The lifting mechanism 1 includes a leg 11, a load-bearing beam 12 and a suspension assembly 13. A plurality of legs 11 are provided, and the legs 11 are composed of columns and column top connecting beams. In order to reinforce the structural strength of the legs 11, a plurality of diagonal braces for reinforcement are fixedly installed between the legs 11. The diagonal braces can be fixed between the legs 11 by welding, or by bolts or hoops. The specific fixing method can be determined according to the specific construction scenario.

[0050] The load-bearing beam 12 is fixedly installed above the support leg 11, and the support leg 11 can support the load-bearing beam 12. The bottom of the support leg 11 is connected to the walking mechanism 2, so as to facilitate the movement of the load-bearing beam 12. The suspension assembly 13 is installed on the load-bearing beam 12 and is used to hoist the steel formwork 3.

[0051] The suspension assembly 13 uses 9 sets of electric hoists to provide lifting power, and only four sets are shown in the figure. The electric hoist used on site is a DHS type 10t chain electric hoist. The electric hoist is synchronized through a remote control system to ensure smooth lifting of the steel formwork 3.

[0052] Reference Figure 1 The walking mechanism 2 includes a rail 21 and a sliding wheel 22. Two rails 21 are provided. Both rails 21 are P43 rails 21, which are fixed to the ground with a pressure plate and a high-strength anchor bolt. The two rails 21 are respectively located on both sides of the retaining wall to be cast. Multiple groups of sliding wheels 22 are provided. Each sliding wheel 22 is rotatably installed at the bottom of the support leg 11, and each sliding wheel 22 is rotatably installed on the corresponding rail 21.

[0053] The locking mechanism 4 includes a hollow mounting seat 41 and a pre-positioning component 42, a linkage component 43 and an unlocking component 44 arranged in the mounting seat 41. Figure 1 and Figure 2The mounting seat 41 is fixed on the ground, and a plug-in port 411 is provided on the top. Two groups of pre-positioning components 42, linkage components 43 and unlocking components 44 are provided, and are symmetrically arranged on both sides of the plug-in port 411;

[0054] When the plug-in board 31 is plugged into the plug-in port 411, the pre-positioning component 42 can guide and pre-clamp the plug-in at the end of the plug-in board 31. At this time, the pre-positioning component 42 only performs a preliminary clamping on the board surface of the plug-in board 31; when the plug-in board 31 continues to be plugged into the mounting seat 41, the plug-in board 31 will drive the two groups of linkage components 43 to move, and the two groups of linkage components 43 drive the corresponding pre-positioning components 42 to rigidly clamp and fix the board surface of the plug-in board 31. At this time, the plug-in board 31 is locked and fixed in the mounting seat 41, so as to lock and fix the steel template 3.

[0055] The unlocking component 44 is used to unlock the lock of the pre-positioning component 42. After pouring a section of retaining wall, the steel formwork 3 needs to be moved to the pouring position of the next section, and the plug-in plate 31 needs to be taken out from the mounting seat 41. Therefore, the unlocking component 44 can be used to unlock the plug-in plate 31, which facilitates the rapid movement of the steel formwork 3.

[0056] The pre-positioning assembly 42 includes a telescopic rod 421, a positioning ball 422, a push piece 423 and a plug-in piece 424. Figure 2 and Figure 3 The telescopic rod 421 adopts a two-stage telescopic method. The telescopic rod 421 is slidably installed in the mounting seat 41 and telescopes along the direction of the plug interface 411. The positioning ball 422 is fixedly installed at the telescopic end of the telescopic rod 421. The push member 423 is a spring. The spring is sleeved and installed on the telescopic end of the telescopic rod 421, and one end is connected to the fixed end of the telescopic rod 421, and the other end is fixedly connected to the fixed ball. The spring can drive the telescopic end of the telescopic rod 421 to extend, so that the positioning ball 422 extends to the plug interface 411;

[0057] The plug-in connector 424 is arranged at the fixed end of the telescopic rod 421. The structure of the plug-in connector 424 is essentially a telescopic structure with a spring sleeve. A partition plate 5 is fixedly installed in the mounting seat 41. The mounting seat 41 and the partition plate 5 are arranged to form a channel 6. A plug-in hole is opened on the partition plate 5. When the end of the plug-in connector 424 is directly opposite to the plug-in hole, the end of the plug-in connector 424 passes through the plug-in hole and extends into the channel 6. At this time, the plug-in connector 424 can limit the fixed end of the telescopic rod 421.

[0058] The linkage assembly 43 includes a guide wheel 431, a rack 432 and a push block 433. Figure 2 and Figure 3The guide wheel 431 is rotatably mounted in the mounting seat 41 and is located on the side of the positioning ball 422 away from the plug-in port 411. The distance between the wheel surfaces of the two guide wheels 431 in the two sets of linkage components 43 is the same as the thickness of the plug-in board 31. When the plug-in board 31 is plugged between the two guide wheels 431, the plug-in board 31 can drive the two guide wheels 431 to rotate;

[0059] Reference Figure 2 and Figure 3 An annular groove 4311 is provided on the outer wall of the guide wheel 431 in the circumferential direction, and the bottom wall of the groove 4311 is provided with a tooth surface. The rack 432 is slidably installed in the mounting seat 41 and meshes with the tooth surface of the bottom wall of the groove 4311. The push block 433 is fixedly installed on one end of the rack 432, and one side of the push block 433 is provided with a wedge-shaped inclined surface. The fixed end of the telescopic rod 421 is in contact with the wedge-shaped inclined surface of the push block 433. When the rack 432 moves toward the direction of the telescopic rod 421, the wedge-shaped inclined surface of the push block 433 can drive the telescopic rod 421 to move toward the direction close to the plug interface 411.

[0060] A pulling member 7 for resetting the rack 432 is provided at the end of the rack 432 away from the push block 433. The pulling member 7 is a spring. When the plug board 31 is not in contact with the guide wheel 431, the pulling member 7 can pull the rack 432 to reset, thereby facilitating subsequent locking.

[0061] The unlocking assembly 44 is used to allow the connector 424 to pass through the plug hole and extend out of the channel 6, so that the telescopic rod 421 can return to a normal state. At this time, the positioning ball 422 no longer abuts against the surface of the plug board 31 under the reset of the telescopic rod 421, and the plug board 31 can be easily removed.

[0062] The unlocking assembly 44 includes a pull rod 441 and a pull handle 442 arranged at one end of the pull rod 441. The pull handle 442 is located outside the mounting seat 41. The pull rod 441 is slidably installed in the channel 6, and a portion of it extends out of the mounting seat 41 from the end of the channel 6. An arc groove is opened on the outer peripheral wall of the pull rod 441, and the end of the connector 424 can pass through the plug hole and extend into the arc groove.

[0063] In other feasible embodiments, a limit rod can be fixed on the outer wall of the pull rod 441, and a guide groove and a limit groove are opened on the inner wall of the mounting seat 41, and the limit rod is slidably engaged in the guide groove, and the guide groove extends along the length direction of the pull rod 441, and the extension direction of the limit groove is perpendicular to the length direction of the guide groove, and one end of the limit groove is connected to one end of the guide groove. When it is necessary to unlock the connector 424, first pull the pull rod 441 to move the limit rod along the direction of the guide groove, so that the limit rod slides to the end of the guide groove, and then rotate the pull handle 442 to make the pull rod 441 drive the limit rod to move into the limit groove. At this time, the position of the pull rod 441 can be limited so that the arc groove on the pull rod 441 will not be directly opposite to the plug-in hole, thereby maintaining the unlocked state of the telescopic rod 421.

[0064] Furthermore, a spring can be provided on the pull rod 441, and the following effect can be achieved: when the connector 424 needs to be locked again, the pull handle 442 is rotated, and the pull rod 441 is automatically reset under the elastic force of the spring, so that the arc groove on the pull rod 441 is directly opposite to the plug hole on the partition 5, and the connector 424 can be inserted into the arc groove through the plug hole, and the pull rod 441 can lock the connector 424 again.

[0065] The implementation principle of the guide rail type slipform system for retaining wall casting in the embodiment of the present application is as follows: when the retaining wall needs to be cast, the two steel templates 3 are first hoisted by an electric hoist to make the bottom of the steel template 3 leave the ground, and then the legs 11 are pulled by a pulling device to move the legs 11 along the steel rails 21 to the next casting position, and then the two steel templates 3 are lowered by an electric hoist, and with the cooperation of the construction personnel, the plug-in board 31 on the steel template 3 is inserted into the mounting seat 41 from the plug-in interface 411 on the mounting seat 41;

[0066] At this time, the plug board 31 will pass through the two positioning balls 422, and under the push of the push member 423, the telescopic rod 421 will drive the two positioning balls 422 to elastically abut against the board surface of the plug board 31, so as to pre-clamp the plug board 31;

[0067] When the plug board 31 continues to be plugged into the mounting seat 41, the plug board 31 will drive the guide wheel 431 to rotate, and the guide wheel 431 will drive the rack 432 to move, and the rack 432 will drive the push block 433 to move. At this time, the wedge-shaped inclined surface of the push block 433 will push the fixed end of the telescopic rod 421. When the maximum compression stroke is reached between the telescopic end and the fixed end of the telescopic rod 421, the positioning ball 422 will rigidly abut against the board surface of the plug board 31.

[0068] At the same time, the plug-in piece 424 will pass through the plug-in hole and be plugged into the channel 6, so that the fixed end and the telescopic end of the telescopic rod 421 are always kept at the maximum compression stroke, so that the two positioning balls 422 are stably abutted and fixed to the plug-in plate 31, thereby quickly positioning and fixing the two steel templates 3;

[0069] After pouring a section of retaining wall, it is necessary to move the position of the steel formwork 3. At this time, it is necessary to first take out the plug-in plate 31 from the mounting seat 41. At this time, first pull the two pull handles 442 to a position away from the mounting seat 41, so that the two pull handles 442 respectively drive the corresponding pull rods 441 to move in the channel 6. At this time, the arc groove on the pull rod 441 will drive the end of the connector 424 to extend out of the channel 6 from the plug-in hole. At this time, the locking of the plug-in plate 31 can be completed, and the suspension assembly 13 can be used to lift the steel formwork 3, so as to facilitate the pouring of the next section of the retaining wall.
