Description

Technical Field

[0001] The invention relates to the technical field of water conservancy construction, and in particular to a concrete lining plate anchoring extraction system and extraction method under flowing water conditions. Background Art

[0002] The functions of large canals or rivers mainly include water supply, irrigation, improving the ecological environment and promoting economic and social development, which not only ensures the effective use of water resources, but also promotes the overall development of the region. During the operation of canals or rivers, water transfer channels and rivers are affected by various factors such as groundwater and operating water level changes, freezing and thawing, and construction quality. The concrete lining slabs may be damaged in the form of cracking, collapse, and anti-floating instability, which will affect the safe operation of the channel. When the lining slab is damaged, it will lead to an increase in local head loss and damage to the anti-seepage system to a certain extent. In severe cases, it will cause the slope soil to soften and lead to slope instability, affecting the safe operation of the channel. In order to avoid further aggravation of deformation and damage of the lining slab and affect the normal water transfer of the main canal, the damaged concrete lining slabs need to be removed and repaired in time.

[0003] Since water flows continuously in canals or rivers all year round, if construction is carried out in rivers, it is usually necessary to form a relatively still water area in the construction area, and to exclude water by building a cofferdam around the damaged concrete lining plate to create dry land construction conditions. However, this limits the time window and spatial scope of construction, and also increases the amount and complexity of the project. Therefore, it is often assisted by a concrete lining plate extraction device. The extraction device is transported to the location of the damaged concrete lining plate by a crane and a truss, and the concrete lining plate is adsorbed by an adsorption mechanism set on the extraction device, and finally extracted ashore by negative pressure. Since the concrete lining plate is generally a solid square structure of 4m*4m and is heavy, the concrete lining plate is underwater for a long time, and there is silt on its surface and a large number of shells attached (shells are shell organisms attached to underwater structures (such as bridges, docks, dams, etc.)). When the concrete lining plate is adsorbed by the adsorption mechanism, it will be affected to a certain extent, such as being difficult to adsorb or easy to fall off, which increases a certain construction period and poses safety hazards, thereby reducing construction efficiency and construction safety. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a concrete lining plate anchoring extraction system and extraction method under flowing water, which solves the problem in the prior art that when the concrete lining plate extraction device extracts the lining plate through negative pressure, it will be affected by the silt and vegetation on the surface of the lining plate and become difficult to adsorb or easily fall off.

DETAILED DESCRIPTION

[0031] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0032] like Figure 1 and Figure 2 As shown, the embodiment of the present invention provides a concrete lining plate anchoring extraction system under flowing water state, comprising:

[0033] Bearing body;

[0034] The mounting frame 5 is provided with a plurality of drills 7 and lockers 8, the plurality of drills 7 and lockers 8 are arranged circumferentially with the mounting frame 5 as the axis, the plurality of lockers 8 are respectively located between two adjacent drills 7, and the drills 7 are provided with drill rods 6, and the lockers 8 are provided with self-tapping bolts 9;

[0035] The rotating unit is arranged on the bearing body and connected to the mounting frame 5, and is used to drive the mounting frame 5 to rotate so as to make the locking device 8 and the drilling device 7 move in a circular motion.

[0036] In the embodiment of the present invention, the mounting frame 5 is provided to carry a plurality of drills 7 and lockers 8. In the installation layout of the plurality of drills 7 and the plurality of lockers 8, the overall shape of the mounting frame 5 is a circular structure, and the drills 7 and lockers 8 are arranged circumferentially with respect to the axis of the mounting frame 5, and the drills 7 and lockers 8 are arranged at intervals from each other. For example, four lockers 8 and four drills 7 are used, and the four lockers 8 are arranged at four sides in an orthogonal direction, and the four drills 7 are arranged at an oblique angle of 45 degrees. When the concrete lining plate is to be extracted, the mounting frame 5 is moved to the designated position of the concrete lining plate by the bearing of the bearing body. The movement mode of the bearing body can be driven by a telescopic truss or a crane. When the bearing body moves the mounting frame 5 to correspond to the concrete lining plate, the drilling device 7 is started so that each drilling device 7 works synchronously and punches holes at the designated position of the concrete lining plate, so that the drilling device 7 drives the drill rod 6 set therein to extend downward and make the drill rod 6 effectively penetrate the surface silt and vegetation layer to drill to the predetermined position. After the depth is reached, the drill rod 6 is automatically withdrawn by the drill 7 to avoid the subsequent movement of the mounting frame 5 causing the drill rod 6 to break. After the drilling is completed, the mounting frame 5 is driven to rotate by the rotating unit. According to the position layout of the four lockers 8 and the four drills 7, the mounting frame 5 is rotated forty-five degrees by the rotating unit so that the four lockers 8 are just aligned with the four hole positions after the processing. At this time, the locker 8 is started to screw out the self-tapping bolt 9 downward until the self-tapping bolt 9 is screwed into the corresponding hole position to stop the locker 8. During the operation of the locker 8 and the drill 7, they can be connected to an external controller, which can be manually controlled or automatically controlled by a program. When the self-tapping bolt 9 is screwed into the hole positions on the mounting frame 5 and the concrete lining board in turn, the concrete lining board can be firmly positioned on the mounting frame 5. Finally, the bearing body is lifted and moved until the concrete lining board is transported to the shore. Compared with the traditional negative pressure fixation, it can provide a stronger fixing force for the extraction of the concrete lining board, and compared with the traditional expansion bolt fixing method, the operation is simpler.

[0037] Based on the above solution, the bearing body includes a first support frame 2 and a second support frame 3 which are spaced apart from each other. The first support frame 2 and the second support frame 3 are both provided with a plurality of mounting seats 15 , and a telescopic member 4 is provided between two corresponding mounting seats 15 .

[0038] In order to more conveniently extract the concrete lining panels, regardless of whether the concrete lining panels are damaged or not, each concrete lining panel always forms a slope structure of the channel or river channel, and the mounting frame 5 carries each drill 7 and locker 8 to make point-like contact with the concrete lining panels to adapt to the inclined slope state of the channel or river channel. The bearing body is set as a mechanism that can be retracted and moved by itself, that is, the first support frame 2 corresponds to the second support frame 3, and the first support frame 2 and the second support frame 3 are connected by a telescopic member 4, so that the first support frame 2, the second support frame 3 and the telescopic member 4 form a frame structure. During the telescopic process of the telescopic member 4, the first support frame 2 and the second support frame 3 can be driven to be close to each other. The first support frame 2 is close to or far away from each other, and under the premise that the first support frame 2 is installed, the extension and contraction of the telescopic member 4 can only drive the second support frame 3 to approach the first support frame 2 or move away from the first support frame 2, thereby achieving the purpose of the movable mounting frame 5. After the self-tapping bolts 9 of the locker 8 are screwed into the concrete lining plate, the telescopic member 4 can be started to shrink the telescopic end of the telescopic member 4, so that the mounting frame 5 follows the movement of the second support frame 3 and approaches the first support frame 2. Since the concrete lining plate has been fixed by the self-tapping bolts 9, the concrete lining plate can be pulled out of the original slope plane by the pulling force of the self-tapping bolts 9, so that the concrete lining plate can be extracted, and the operation is more convenient and stable. Due to the operation in water, the telescopic member 4 preferably adopts a hydraulic rod to control the extension and contraction of its telescopic end by hydraulic means.

[0039] Specifically, the second support frame 3 is provided with a guide rod 10 , and the first support frame 2 is provided with a guide hole corresponding to the guide rod 10 , and the end of the guide rod 10 passes through the guide hole.

[0040] In order to prevent the telescopic end and the fixed end of the telescopic member 4 from being subjected to the torsion of the first support frame 2 and the second support frame 3, which causes the telescopic end and the fixed end of the telescopic member 4 to have radial forces, under the action of the guide rod 10, the guide rod 10 is fixedly installed on the second support frame 3, and the fixing method includes but is not limited to screw connection, which is convenient for assembly and later maintenance. Then the first support frame 2 is sleeved on each guide rod 10 with a connection relationship between the hole and the rod, so that the first support frame 2 can slide along the axial direction of the guide rod 10. The cooperation between the guide rod 10 and the guide hole ensures that the relative position between the first support frame 2 and the second support frame 3 is always consistent, effectively avoiding unnecessary lateral displacement or torsion of the first support frame 2 and the second support frame 3, thereby improving the stability and reliability of the system. Because the flow of water will exert additional force on the load-bearing body, the cooperation between the guide rod 10 and the guide hole is particularly important under the water flow state, which significantly enhances the functionality and reliability of the load-bearing body and ensures the efficient operation of the concrete lining plate anchoring extraction system.

[0041] At the same time, the first support frame 2 is provided with a guide sleeve 14 coaxial with the guide hole, and the guide rod 10 passes through the guide sleeve 14. The guide sleeve 14 is fixed on the first support frame 2. The fixing method includes but is not limited to welding. The guide sleeve 14 fixedly installed on the first support frame 2 is coaxially arranged with the guide hole, which increases the support area between the guide hole and the guide rod 10, and can better limit the radial movement of the guide rod 10 to prevent it from shaking or offset during operation.

[0042] Based on the above solution, the rotating unit includes a rotating member 13 arranged on the second support frame 3 and a mounting plate 11 arranged on the mounting frame 5 . The mounting plate 11 is provided with a driving rod 12 , and the driving rod 12 is transmission-connected to the rotating member 13 .

[0043] Specifically, when the rotation of the mounting frame 5 is realized by the rotating unit, the rotating member 13 is connected to the external controller, the mounting plate 11 is fixedly connected to the mounting frame 5, and the mounting frame 5 is connected to the rotating member 13 through the driving rod 12. When the rotating member 13 is started, the output shaft of the rotating member 13 is rotated to drive the driving rod 12 to rotate, so that the driving rod 12 drives the mounting plate 11 to rotate. In the controller, the rotating member 13 can be controlled by a program to rotate forty-five degrees each time to match the position change of the drill 7 and the locker 8 on the mounting frame 5, and realize the precise control of the rotation angle. At the same time, in order to ensure the stability of the mounting plate 11, a limit ring can be set on the side of the mounting plate 11 close to the second support frame 3, and the limit ring is rotated to set the bottom of the second support frame 3, and the mounting plate 11 and the auxiliary structure are limitedly installed through the second support frame 3 to play a bearing role. At the same time, when the mounting plate 11 is driven by the rotating member 13, the rotating member 13 will not be affected by the force in other directions brought by the mounting plate 11, thereby ensuring the service life of the rotating member 13. The rotating member 13 is preferably a hydraulic motor.

[0044] At the same time, the mounting plate 11 is provided with a plurality of assembly bolts 17, and the plurality of assembly bolts 17 are all connected to the mounting frame 5. In the initial stage of assembling the mounting plate 11 and the mounting frame 5, the plurality of assembly bolts 17 can be used to fix the mounting frame 5 and the mounting plate 11 together. The mounting plate 11 and the mounting frame 5 can be quickly installed and disassembled, which is convenient for maintenance, inspection or replacement of parts, indirectly reducing downtime and improving work efficiency. At the same time, in assembly, multiple assembly bolts 17 are distributed on the entire connection surface, which can distribute the load more evenly and avoid the risk of damage caused by local stress concentration.

[0045] Based on the above solution, it also includes a support frame 1, a first support frame 2 extends upward to form a mounting portion 16, and the support frame 1 is provided with a driving unit, which is connected to the mounting portion 16 and is used to drive the bearing body to slide along the length direction of the support frame 1.

[0046] The support frame 1 is a crossbeam structure. With the cooperation of the driving unit, the support frame 1 can drive the bearing body to move along the length direction of the support frame 1, and at the same time play the role of bearing the bearing body, without the need for hoisting. Figure 2 As shown, taking the damaged concrete lining plate as an example, and dividing the damaged concrete lining plate into four plates A, B, C, and D, after the concrete lining plates of plates A and C are extracted in the first work, the bearing body can drive the mounting frame 5 to slide along the length direction of the bearing frame 1 under the action of the driving unit, so that the mounting frame 5 drives each drill 7 and locker 8 to move from plates A and C to plates B and D, and the concrete lining plates corresponding to plates B and D are extracted. At the same time, for concrete lining plates of different sizes, the concrete lining plates can be cut along the direction of the arrow, and the confirmation of the arrow direction can correspond to the direction of the crack. In one extraction work, it can be listed as a reference. When the concrete lining plates of one column are extracted, the bearing body can be moved to the next column by the action of the driving unit until the concrete lining plates of each column are extracted.

[0047] Specifically, the driving unit includes a transmission member 21 disposed on the mounting portion 16 and a slide rail 18 disposed on the side of the carrier 1 . The transmission shaft of the transmission member 21 is provided with a rolling member, and the rolling member is in rolling contact with the inner side of the slide rail 18 .

[0048] In assembly, the transmission member 21 is fixed to the mounting portion 16 by means of screws. When the bearing body is moved by the driving unit, the transmission member 21 is started so that the transmission shaft of the transmission member 21 rotates to drive the rolling member to rotate, so that the rolling member moves in the slide rail 18, thereby driving the various accessories below the mounting portion 16 to follow the movement, thereby achieving the replacement of the position of the concrete lining plate. The transmission member 21 is preferably a hydraulic motor for underwater use.

[0049] Specifically, the rolling element is a transmission gear 19, and a transmission rack 20 is provided on the inner side of the slide rail 18, and the transmission gear 19 is meshed with the transmission rack 20; compared with driving the load-bearing body to walk on the load-bearing frame 1 by rolling friction, with the support of the transmission gear 19 and the transmission rack 20, the meshing between the transmission gear 19 and the transmission rack 20 provides a stable mechanical connection, reduces the slipping or position deviation problems that may be caused by sliding friction, and ensures the stability and reliability of the system. At the same time, it can also withstand larger axial and radial loads, and when working underwater, the meshing between the transmission gear 19 and the transmission rack 20 can maintain stable working performance, and realize rapid starting and stopping, and quickly adjust the position, thereby speeding up the construction progress.

[0050] The embodiment of the present invention further provides a method for extracting anchors of concrete lining plates under flowing water, including the above-mentioned system for extracting anchors of concrete lining plates under flowing water, and further including the following steps:

[0051] S1: Initial cutting: cutting along the four edges of the damaged lining plate to separate the damaged lining plate from other lining plates to form the lining plate to be extracted;

[0052] S2: cutting again, cutting the lining plate to be extracted into at least two lining plates with four sides having relatively uniform lengths;

[0053] S3: drilling holes, moving the bearing body to the position of one of the lining plates, opening a plurality of drills 7 to extend the drill rod 6 to drill holes in the lining plate at the position, after the drilling is completed, the drill rod 6 is retracted and separated from the lining plate, the rotating unit is started, the locking device 8 is moved to the corresponding hole position by the rotation of the mounting frame 5, and the self-tapping bolt 9 automatically fed in is screwed into the hole position through the locking device 8;

[0054] S4: Extraction, lifting the mounting frame 5, transmitting the force to the lining plate through the self-tapping bolts 9, so that the lining plate is upwardly separated from other lining plates, and the lining plate is extracted to the shore by moving the bearing body, and the self-tapping bolts 9 are withdrawn through the reverse rotation of the locker 8, and the lining plate is taken out;

[0055] S5: Repeat S3 and S4 until all lining panels are extracted.

[0056] Specifically, in S1, after the four edges of the damaged lining plate are initially cut, an easily tearable portion is left between the bottom of the damaged lining plate and the bottoms of other lining plates.

[0057] Specifically, in S2, an easy-to-tear portion is left between the bottoms of each lining plate.

[0058] Specifically, the thickness of the tear portion is 1-3 cm.

[0059] In the above method, cutting is performed along the four edges of the damaged lining plate in S1, thereby ensuring effective separation of the damaged part from the intact part, which can minimize the impact on the surrounding structure and avoid unnecessary damage. In S2, the lining plate to be extracted is further cut into at least two lining plates, so that the volume of each lining plate is reduced and it is easier to manage and carry. At the same time, by reserving 1-3 cm thickness in S2 for cutting in an easy-to-break manner, additional damage caused by directly cutting through the lining plate is avoided, and the impact on the surrounding structure is reduced. The use of the drill 7 and the locker 8 in S3 provides a stable anchor point, ensuring that the lining plate will not accidentally fall off or shift during the lifting process, thereby increasing the safety of the operation. The movement of the load-bearing body in S4 simplifies the extraction process of the lining plate. The entire extraction method reduces the need for manual intervention, reduces the labor intensity of workers, and ensures the stability of the lining plate during extraction.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
