Abstract

The application provides a synchronous assembling equipment for underground continuous walls and a construction process thereof. The auxiliary centering mechanism is arranged to correct the position of the continuous wall hoisted by the hoisting and feeding system to the left side of the cantilever frame, so that the continuous wall is kept in a vertical state and is lowered in a posture aligned with the cantilever frame. The telescopic fixing mechanism is used to fix the continuous wall after the continuous wall is aligned with the cantilever frame, so as to ensure the maintenance and stability of the lowering state of the continuous wall, thereby improving the assembling efficiency and assembling effect of the continuous wall and improving the stability of the formed wall surface. Since the auxiliary centering mechanism, the telescopic fixing mechanism, the supporting plate mechanism and the double-milling slot wheel are all arranged on the cantilever frame, the effect of wall slot generation and prefabricated wall assembling cooperation can be achieved, so that the overall construction efficiency can be greatly improved, the slotting machine and other equipment are limited when the continuous wall is placed in the traditional construction process, the cost is reduced, and the construction period is shortened.

Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to equipment for synchronous assembly of underground continuous walls. Background Technology

[0002] Currently, in the construction of diaphragm walls, trenching and wall installation are typically carried out as two separate processes. First, trenching is performed using equipment such as twin-wheel trenching machines. After trenching is completed, precast diaphragm wall panels are hoisted and installed piece by piece using lifting equipment. This traditional method suffers from problems such as loose process coordination and low equipment efficiency, resulting in long construction cycles and high overall costs. Furthermore, during the lowering of wall panels, the lack of effective centering and positioning aids often leads to wall tilting and difficulty in posture control, affecting not only installation accuracy but also the stability of the trenched wall surface. Simultaneously, in traditional processes, trenching machines and hoisting equipment often need to operate alternately, leading to equipment constraints and low site utilization, further limiting construction efficiency. Therefore, there is an urgent need for a new integrated equipment that can integrate trenching and wall installation functions, enabling simultaneous trench and wall construction, and possessing automatic centering and fixing capabilities to improve the overall efficiency and quality stability of diaphragm wall construction.

[0048] Figure 1 This is a schematic structural diagram of a diaphragm wall synchronous assembly equipment, such as... Figure 1As shown, and with reference Figures 2 to 10 The present invention provides a synchronous assembly equipment for diaphragm walls, which includes a twin-wheel milling machine 100, a hoisting and feeding system 200 and a transport and lifting system 300.

[0049] The twin-wheel grooving machine 100 includes a vehicle body, a cantilever frame 120, multiple auxiliary alignment mechanisms 130, multiple telescopic fixing mechanisms 140, a pallet mechanism 150, and twin grooving wheels 160. The cantilever frame 120 is mounted on the vehicle body. The auxiliary alignment mechanisms 130 are mounted on the cantilever frame 120, and the multiple auxiliary alignment mechanisms 130 are evenly distributed vertically. The auxiliary alignment mechanisms 130 are used to align the continuous wall 400 with the cantilever frame 120. The telescopic fixing mechanisms 140 are mounted on the cantilever frame 120, and the multiple telescopic fixing mechanisms 140 are evenly distributed vertically. The telescopic fixing mechanisms 140 are used to fix the continuous wall 400 when it is aligned with the cantilever frame 120. The pallet mechanism 150 is located at the bottom of the cantilever frame 120 and is used to hold the continuous wall 400. The twin grooving wheels 160 are mounted at the bottom of the cantilever frame 120.

[0050] The hoisting and feeding system 200 is used to transport the diaphragm wall 400 to one side of the cantilever 120. The transport and lifting system 300 is used to transfer the diaphragm wall 400 to the hoisting and feeding system 200 at a preset position.

[0051] Specifically, the auxiliary alignment mechanism 130 corrects the position of the continuous wall 400 on the left side of the cantilever 120 after the hoisting and feeding system 200 is hoisted, thus ensuring the continuous wall 400 remains vertical and aligned with the cantilever 120 during lowering. Furthermore, the pallet mechanism 150 places the continuous wall 400 so that it descends synchronously with the cantilever 120. Furthermore, the telescopic fixing mechanism 140 secures the continuous wall 400 after it is aligned with the cantilever 120, ensuring the stability and maintaining the lowered state of the continuous wall 400. This improves the assembly efficiency and effect of the continuous wall 400 and enhances the stability of the trench 500 wall surface. Furthermore, since the auxiliary centering mechanism 130, telescopic fixing mechanism 140, pallet mechanism 150, and double milling wheel 160 are all mounted on the cantilever frame 120, the effect of coordinated operation of wall groove generation and prefabricated wall assembly can be achieved, thereby greatly increasing the overall construction efficiency. In the traditional construction process, the grooving machine and other equipment are limited when placing continuous walls, reducing costs and shortening the construction period.

[0052] Furthermore, the hoisting and feeding system 200 can also temporarily fix the continuous wall 400 below to the slot opening, so that one continuous wall 400 can be stacked on top of it and gradually stacked down until the continuous wall 400 is placed at the bottom of the slot. During this process, the centering mechanism 130, the telescopic fixing mechanism 140 and the pallet mechanism 150 provide stability.

[0053] During operation, the twin-wheel grooving machine 100 performs grooving operations on a preset ground area. After grooving is completed, the hoisting and feeding system 200 is installed on the left side of the cantilever 120. The transport and lifting system 300 transfers the diaphragm wall 400 from the preset position to the hoisting and feeding system 200 and lifts the diaphragm wall 400 to a vertical position. The hoisting and feeding system 200 hoists the diaphragm wall 400 to the left side of the cantilever 120, and the auxiliary centering mechanism 130 centers and corrects the diaphragm wall 400 to align it with the cantilever 120. At the same time, the diaphragm wall 400 is stably lowered onto the pallet mechanism 150. Then, the telescopic fixing mechanism 140 is activated to further fix the diaphragm wall 400, ensuring that the diaphragm wall 400 is fixed on the cantilever 120. The cantilever 120 lowers the continuous wall 400 into the trench 500. When the upper end of the continuous wall 400 is located at the opening of the trench 500, the hoisting and feeding system 200 extends a temporary fixing mechanism to further secure the continuous wall 400. The hoisting and feeding system 200 places the next continuous wall 400 on top of the first continuous wall 400. After placement, the hoisting and feeding system 200 releases the fixation on the first continuous wall 400, and the cantilever 120 continues to lower the continuous wall 400. This stacking of continuous walls 400 is repeated until the continuous wall 400 reaches the preset depth.

[0054] In some embodiments of the present invention, such as Figure 5 As shown, the auxiliary centering mechanism 130 includes two centering clamps 131, two centering gears 132, a centering rack 133, and a centering hydraulic cylinder. The two centering clamps 131 are symmetrically arranged on both sides of the cantilever frame 120. The centering clamps 131 are rotatably connected to the cantilever frame 120, and when the two centering clamps 131 are configured to rotate relative to each other, they clamp the continuous wall 400. The centering gears 132 are rotatably mounted on the cantilever frame 120. Each centering gear 132 is fixedly connected to the rotating shaft of one centering clamp 131. The centering rack 133 is horizontally slidable on the cantilever frame 120, and is a double-sided rack that meshes with both centering gears 132 simultaneously. The centering hydraulic cylinder is mounted on the cantilever frame 120 and connected to the centering rack 133, used to drive the centering rack 133 in reciprocating motion.

[0055] Specifically, the sliding of the centering rack 133 can synchronously drive the two centering gears 132 to rotate, thereby driving the opening and closing of the two centering clamps 131. When the two centering clamps 131 rotate relative to each other, the centering clamps 131 correct the vertical direction of the continuous wall 400, so that the right side of the continuous wall 400 corresponds to the left side of the cantilever 120, so as to facilitate the subsequent telescopic fixing mechanism 140 to fix the continuous wall 400 and ensure the splicing quality of the continuous wall 400.

[0056] Furthermore, in the initial state, the centering clamp 131 is in a retracted state that fits against the cantilever 120. After the telescopic fixing mechanism 140 fixes the continuous wall 400, the centering clamp 131 returns to the retracted state under the drive of the centering hydraulic cylinder, thereby avoiding interference contact between the centering clamp 131 and the inner wall of the trench 500 during the opening process.

[0057] In some embodiments of the present invention, such as Figure 2 , Figure 3 and Figure 4 As shown, the diaphragm wall 400 has multiple connection holes 410. The cantilever frame 120 has multiple fixing slots, and the telescopic fixing mechanism 140 includes a telescopic fixing arm 141 and a fixing arm hydraulic cylinder 142. The telescopic fixing arm 141 is slidably inserted into the fixing slot and is used to insert into the connection hole 410. The fixing arm hydraulic cylinder 142 is mounted on the cantilever frame 120 and connected to the telescopic fixing arm 141.

[0058] Specifically, the diaphragm wall 400 itself has connection holes 410 for lateral connection. The telescopic fixing arm 141 is designed as a rectangular column structure, with the circumscribed circle radius gradually increasing from the front end to the rear end. Furthermore, when the diaphragm wall 400 is aligned with the cantilever frame 120, the connection holes 410 and telescopic fixing arms 141 correspond, and when multiple telescopic fixing arms 141 are inserted into their respective connection holes 410, the diaphragm wall 400 is fixed to the cantilever frame 120. Furthermore, the design of the telescopic fixing arms 141 allows for the use of the diaphragm wall 400 itself for fixing, simplifying the device structure and increasing its adaptability.

[0059] In some embodiments of the present invention, such as Figure 7 and Figure 8 As shown, two rectangular slots 1412 are symmetrically arranged on both sides of the telescopic fixing arm 141, and multiple limiting holes 1413 are evenly distributed on the edges of the rectangular slots 1412. The telescopic fixing arm 141 defines an installation cavity 1411 inside. The telescopic fixing mechanism 140 also includes two outward expansion plates 143, two wedge-shaped push blocks 144, a wedge-shaped push rod 180, a reset assembly, and a push rod hydraulic cylinder 190.

[0060] An expansion plate 143 is embedded in a rectangular groove 1412. The expansion plate has multiple limiting posts 1431 that can be inserted into limiting holes 1413, allowing the expansion plate 143 to move outward. A wedge-shaped push block 144 is disposed in the mounting cavity 1411, each wedge-shaped push block 144 being fixedly connected to an expansion plate 143. The inclined surface of the wedge-shaped push block 144 is configured to push the expansion plate 143 outward when subjected to a leftward pushing force. A wedge-shaped push rod 180 is horizontally disposed in the mounting cavity 1411, sliding left and right, with one end contacting the inclined surface of the wedge-shaped push block 144. A reset assembly is used to reset the expansion plate 143 when the wedge-shaped push rod 180 slides to the right. A push rod hydraulic cylinder 190 is disposed on the telescopic fixed arm 141 and connected to the wedge-shaped push rod 180.

[0061] Specifically, the rectangular groove 1412 is connected to the mounting cavity 1411, and the outer surface of the expansion plate 143 is provided with a rubber plate to increase the friction between the expansion plate 143 and the inner wall of the connecting hole 410. The expansion plate 143 is embedded in the rectangular groove 1412 so that the expansion plate 143 coincides with the outer surface of the telescopic fixing arm 141. Furthermore, the two expansion plates 143 are provided to increase the connection strength between the telescopic fixing arm 141 and the connecting hole 410 when the telescopic fixing arm 141 is located in the connecting hole 410 and the expansion plates 143 move outward to contact the inner wall of the connecting hole 410, thereby reliably fixing the telescopic fixing arm 141 and the continuous wall 400 in the downward process and resisting external lateral and longitudinal forces.

[0062] Furthermore, due to the wedge-shaped push block 144, the left end of the wedge-shaped push rod engages with the lower part of the wedge-shaped push block 144, thereby changing the leftward force on the wedge-shaped push block 144 into a force that moves the outward expansion plate 143, thus realizing the outward movement of the outward expansion plate 143 until it contacts the inner wall of the connecting hole 410. Furthermore, the push rod hydraulic cylinder 190 is activated when the telescopic fixed arm 141 is fully inserted into the connecting hole 410.

[0063] In some embodiments of the present invention, such as Figure 7 , Figure 9 and Figure 10 As shown, a T-slot is provided on the inclined surface of the wedge-shaped pusher 144. The reset assembly includes a reset wedge 170; the reset wedge 170 has two inclined surfaces, and each reset wedge 170 has a T-shaped slider 171 that can slide into the T-slot 1441. The reset wedge 170 is connected to the wedge-shaped pusher 180 so that the reset wedge 170 can slide left and right as the wedge-shaped pusher 180 drives it.

[0064] Specifically, the T-slot 1441 and the T-slider 171 are symmetrically arranged so that the T-slider 171 can be inserted into the T-slot 1441 and slide. The mutual cooperation between the T-slot 1441 and the T-slider 171 can drive the two wedge-shaped push blocks 144 to reset inward when the wedge push rod 180 resets and retracts, thereby driving the two outer expansion plates 143 to reset inward.

[0065] In some embodiments of the present invention, such as Figure 4 As shown, the head cross-section of the telescopic fixing arm 141 is trapezoidal. Specifically, it is thinner at the head and thicker at the tail, enabling automatic alignment of the head connection hole 410 of the telescopic fixing arm 141 with small deviations.

[0066] In some embodiments of the present invention, such as Figure 6 As shown, the bottom of the cantilever 120 is provided with a track groove. The support plate mechanism 150 includes a telescopic support plate 151 and a support plate hydraulic cylinder 152. The telescopic support plate 151 is slidably inserted into the track groove and is used to support and place the continuous wall 400. The support plate hydraulic cylinder 152 is mounted on the cantilever 120 and connected to the telescopic support plate 151.

[0067] Specifically, the telescopic pallet 151 is the main load-bearing structural component during the lowering process of the continuous wall 400. It has a one-way degree of freedom for telescopic retraction. After the continuous wall 400 is lowered to the bottom, the telescopic pallet 151 is retracted into the track groove.

[0068] In some embodiments of the present invention, a plurality of bullseye bearings are arrayed on the telescopic tray 151. Specifically, bullseye bearings are embedded in the telescopic tray 151 to facilitate the smooth removal of the telescopic tray 151.

[0069] In some embodiments of the present invention, such as Figure 1 As shown, the hoisting and feeding system 200 includes a hoisting frame and a lifting device. The hoisting frame is located on the left side of the cantilever 120. The lifting device is mounted on the hoisting frame and is used to hoist the diaphragm wall 400 to the left side of the cantilever 120. The transport and lifting system 300 includes a transport vehicle and a lifting device. The lifting device is mounted on the transport vehicle and is used to lift the horizontally placed diaphragm wall 400 from a horizontal state to a vertical state, thereby allowing the lifting device to lift the diaphragm wall 400.

[0070] This invention provides a construction process for a synchronous assembly device for diaphragm walls, used in any of the aforementioned synchronous assembly devices for diaphragm walls, such as... Figure 11 As shown, the construction process of the underground continuous wall synchronous assembly equipment includes:

[0075] S500: The centering clamp 131 centers and clamps the continuous wall 400, and causes the telescopic support plate 151 to extend outward;

[0076] S600: The continuous wall 400 is placed on the telescopic support plate 151;

[0077] S700: The telescopic fixed arm 141 is inserted into the connection hole 410 of the diaphragm wall 400;

[0078] S800: The cantilever 120 descends to a preset height, and the next section of continuous wall 400 is placed on top of the continuous wall 400. The continuous wall 400 is stacked repeatedly until the continuous wall 400 reaches the preset depth.

[0079] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
