Description

Technical Field

[0001] The invention relates to the technical field of water conservancy construction, and in particular to equipment and a method for repairing a concrete lining plate in a flowing water state. Background Art

[0002] The functions of large-scale 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 slab needs to be repaired in time.

[0003] Due to the continuous flow of water in canals or rivers all year round, the repair of underwater damaged lining plates is currently mainly carried out by dry construction using cofferdams or underwater construction using divers. When divers use underwater construction, they are affected by the water depth and need to carry professional equipment into the water. The visibility of the divers and the construction safety cannot be guaranteed, the operation risk is high, and the overall construction efficiency is reduced. If dry construction is carried out using cofferdams, it is necessary to build cofferdams around the damaged concrete lining plates to exclude water areas and create dry land construction conditions. This is also inefficient and increases the complexity of construction. Summary of the invention

[0039] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0040] like Figure 1 As shown, the embodiment of the present invention provides a concrete lining plate repairing equipment under flowing water state, comprising:

[0041] The truss 1 is arranged along the depth direction of the channel surface, and one end of the truss 1 is the water inlet end, and the other end is the water outlet end. The truss 1 is slidably provided with a slide 2, and the slide 2 moves back and forth on the truss 1 in the direction of the water outlet end or the water inlet end;

[0042] The telescopic unit 3 has a mounting end and a working end, the mounting end is slidably arranged at the bottom end of the truss 1 to slide along the width of the truss 1, and the working end is provided with a rotating member 6;

[0043] The operation module includes a cutting unit 4 and a disassembling unit 5. The cutting unit 4 and the disassembling unit 5 are selectively configured on the rotating member 6 according to the operation content.

[0044] In an embodiment of the present invention, the truss 1 is composed of various segments. The segments are prefabricated in the factory at the initial stage. Before the operation, the segments are transported to the shore to be repaired, and the segments are spliced ​​to form the truss 1. The truss 1 is hoisted into the water by an external hoisting equipment such as a crane, or the truss 1 is provided with driving rollers to slide into the water, so that the length direction of the truss 1 is arranged downward along the slope of the channel surface, and after the truss 1 enters the water, there is an inlet end (the part entering the water) and an outlet end (the part above the water surface). The slide 2 in the initial state is located at the outlet end of the truss 1 to facilitate the subsequent installation of the operation module.

[0045] The movement of the slide 2 may be driven by external equipment, such as a crane and a suspension rope, a winch and a traction rope, etc. When repairing the damaged lining plate, it is cut first, and the cutting unit 4 is installed on the rotating part 6 of the slide 2, and the slide 2 is controlled to move to drive the cutting unit 4 into the water. During the continuous movement of the slide 2, the cutting unit 4 is moved to the designated repair area. When the cutting unit 4 is started, the cutting unit 4 is moved down to the damaged area of ​​the concrete lining plate through the cooperation of the telescopic unit 3. During cutting, since the mounting end of the telescopic unit 3 can slide on the bottom end of the truss 1, the telescopic unit 3 can drive the cutting unit 4 to cut along the width direction of the truss 1 when sliding to form a first cutting line, and the slide 2 is moved on the truss 1 to cut a second cutting line perpendicular to the first cutting line, and the cutting unit 4 is controlled to retreat along the width of the truss 1 to form a third cutting line. Finally, the slide 2 retreats on the truss 1, and the four cutting lines form a closed cutting space to complete the cutting of the damaged lining plate. After the cutting is completed, the slide 2 is controlled to move the cutting unit 4 to the water outlet, and the cutting unit 4 is disassembled.

[0046] According to the content of the operation, the cut lining plate needs to be taken out, that is, by installing the disassembly unit 5 on the rotating part 6, and controlling the movement of the slide 2 to drive the disassembly unit 5 into the water, and during the continuous movement of the slide 2, the disassembly unit 5 is moved to the cut lining plate area, and the disassembly unit 5 is controlled to descend by the telescopic unit 3, and the disassembly unit 5 is connected with the cut lining plate. After the connection, the telescopic unit 3 is contracted to separate the lining plate from the channel surface, and the lining plate installed on the disassembly unit 5 is transported to the shore and disassembled by the movement of the slide 2.

[0047] During the entire cutting and disassembling operation of the lining plates, each damaged lining plate can be cut first, and then the disassembly unit 5 can be replaced and put into water for disassembly. The disassembly unit 5 can be fixed with bolts to install and disassemble the lining plates.

[0048] Finally, the new lining plate is installed. The new lining plate is fixed on the shore through the disassembly and assembly unit 5, and the lining plate is lifted through the telescopic unit 3. Under the movement of the slide 2, the lining plate can be moved to the specified position, and the telescopic unit 3 is extended again to lower the lining plate to the corresponding cutting position. The reciprocating operation is repeated to complete all the lining plate installation operations.

[0049] Based on the above scheme, if Figure 3 As shown, the telescopic unit 3 includes a fixed frame 302 slidably arranged on the slide 2 and a movable frame 303 connected to the rotating member 6 . The movable frame 303 is provided with a telescopic rod 304 , and the telescopic end of the telescopic rod 304 is connected to the fixed frame 302 .

[0050] Specifically, when the telescopic unit 3 is working, the telescopic end of the telescopic rod 304 is extended or shortened, so that the movable frame 303 can be moved away from or close to the fixed frame 302, thereby making the rotating member 6 move away from or close to the fixed frame 302, so as to realize the lowering or lifting of the cutting unit 4 and the disassembling unit 5. At the same time, the movable frame 303 is fixedly provided with a guide rod 305, and the end of the guide rod 305 passes through the fixed frame 302. In order to prevent the telescopic end and the fixed end of the telescopic rod 304 from being subjected to the torsion of the fixed frame 302 and the movable frame 303, resulting in the telescopic end and the fixed end of the telescopic rod 304 having a radial force, under the action of the guide rod 305, the guide rod 305 is fixedly installed on the movable frame 303, and the fixing method includes but is not limited to The screw connection is convenient for assembly and later maintenance. Then the fixed frame 302 is sleeved on each guide rod 305 with the connection relationship between the hole and the rod, so that the movable frame 303 can slide along the axial direction of the guide rod 305. The guide rod 305 ensures that the relative position between the fixed frame 302 and the movable frame 303 is always consistent, effectively avoiding unnecessary lateral displacement or twisting of the fixed frame 302 and the movable frame 303, thereby improving the stability and reliability of the system. Because the flow of water will exert additional force on the bearing body, the guide rod 305 is particularly important under the water flow state, which significantly enhances the functionality and reliability of the telescopic unit 3 and ensures the stability of the subsequent cutting unit 4 and the disassembly unit 5 during operation. The telescopic rod 304 can be a hydraulic rod or a jack.

[0051] Based on the above scheme, if Figure 4 As shown, the rotating member 6 includes a transmission 605, which is arranged on the movable frame 303. The bottom surface of the movable frame 303 is provided with a mounting plate 602, and the mounting plate 602 is provided with a rotating rod 601. The rotating rod 601 passes through the movable frame 303 and is connected to the transmission 605; the transmission 605 adopts a motor, and the mounting plate 602 is connected to the output shaft of the transmission 605 through the rotating rod 601. When the transmission 605 is working, the mounting plate 602 can be driven to rotate by the rotation of the output shaft. At the same time, when the rotating member 6 cooperates with the cutting unit 4 or the disassembly unit 5:

[0052] Take the cooperation with cutting unit 4 as an example:

[0053] like Figure 3 As shown, the cutting unit 4 includes a driver 401 arranged on a mounting plate 602, the driver 401 is provided with a fixed seat 405, the fixed seat 405 and the driving shaft of the driver 401 are both provided with pulleys 402, the two pulleys 402 are connected by a belt 403, and the pulley 402 located on the fixed seat 405 is provided with a cutting knife 404.

[0054] Specifically, when the lining plate is cut by the cutting unit 4, the driver 401 is started so that the driving shaft of the driver 401 rotates to drive the pulley 402 set thereon to rotate, thereby driving the other pulley 402 and the cutting knife 404 connected to the other pulley 402 to rotate under the action of the belt 403. When the telescopic rod 304 is extended, the cutting knife 404 can be driven by the movable frame 303 to contact the lining plate and implement cutting. When the fixed frame 302 slides at the bottom of the slide 2, the cutting of one side of the lining plate can be achieved. After cutting to the specified position, the telescopic rod 304 is shortened to control the cutting knife 404 to separate from the lining plate. At this time, under the action of the rotating member 6, the transmission 605 is started to drive the mounting plate 602 to rotate to change the cutting direction of the cutting knife 404 until the entire damaged lining plate is cut.

[0055] The driver 401 preferably adopts a motor, and a housing can be provided outside the motor to waterproof the driver 401. Since the fixing seat 405 is subjected to the pulling force of one of the pulleys 402, Figure 3 As shown, the fixing seat 405 is provided with a stiffening rib 406, and the stiffening rib 406 is connected to the driver 401. The provision of the stiffening rib 406 can increase the stability of the fixing seat 405 so that it will not be deformed during long-term use.

[0056] Take the cooperation with the disassembly unit 5 as an example:

[0057] In order to provide a more stable installation for the lining plate, Figures 4 to 6 As shown, the disassembly and assembly unit 5 includes a mounting frame 501 arranged on a mounting plate 602, the mounting frame 501 is provided with a plurality of drills 504 and lockers 502, the plurality of drills 504 and lockers 502 are all arranged circumferentially with the mounting frame 501 as the axis, the plurality of lockers 502 are respectively located between two adjacent drills 504, and the drill 504 is provided with a drill rod 505, and the locker 502 is provided with a self-tapping bolt 503.

[0058] The mounting frame 501 is provided to carry a plurality of drills 504 and a plurality of lockers 502. In the mounting arrangement of the plurality of drills 504 and the plurality of lockers 502, the overall shape of the mounting frame 501 is a circular structure (eg Figure 5As shown in the figure, each drill 504 and locker 502 are arranged in the circumferential direction of the axis of the mounting frame 501, and each drill 504 and locker 502 are arranged at intervals. Taking four lockers 502 and four drills 504 as an example, the four lockers 502 are arranged at four sides in an orthogonal direction, and the four drills 504 are arranged at an oblique angle of 45 degrees. When the damaged concrete lining plate is extracted, the entire disassembly and assembly unit 5 is moved to the position after cutting by the slide 2, and the telescopic rod 304 is extended to lower the installation. The mounting frame 501 is moved to a certain position, and then the drilling device 504 is started, so that each drilling device 504 works synchronously and drills holes in the specified position of the concrete lining plate, so that the drilling device 504 drives the drill rod 505 set therein to extend downward, and after drilling to a predetermined depth, the drill rod 505 is automatically withdrawn by the drilling device 504 to prevent the drill rod 505 from breaking due to subsequent movement of the mounting frame 501. After the drilling is completed, the mounting frame 501 is driven to rotate by the rotating unit, and the mounting frame 501 is started according to the position layout of the four locking devices 502 and the four drilling devices 504. The transmission device 605 drives the mounting plate 602 to rotate and controls the rotation angle of the mounting plate 602, so that the mounting frame 501 is rotated forty-five degrees to align the four locking devices 502 with the four holes after processing. At this time, the locking device 502 is started to screw out the self-tapping bolts 503 downward until the self-tapping bolts 503 are screwed into the corresponding holes to stop the locking device 502. During the operation of the locking device 502, the drilling device 504 and the transmission device 605, they can be connected to an external controller. , which can be controlled manually or automatically by a program. When the self-tapping bolts 503 are screwed into the holes on the mounting frame 501 and the concrete lining plate in sequence, the concrete lining plate can be firmly positioned on the mounting frame 501. At this time, the telescopic rod 304 is started again to shrink the telescopic rod 304 to lift the mounting frame 501 and the lining plate at the bottom of the mounting frame 501, and the lining plates are separated. Finally, the concrete lining plates are transported to the shore by moving the slide 2, and the movement is repeated until all the lining plates are extracted.

[0059] like Figure 5As shown, after the damaged lining plate is cut, four plates ABCD can be respectively arranged according to the shape of the lining plate, and the four plates can be lifted respectively by the disassembly and assembly unit 5 to improve efficiency. When all the lining plates are extracted, the new lining plates can be installed again by the disassembly and assembly unit 5. During installation, due to the heavy weight of the entire lining plate, the lining plate can be divided into two parts, and the water-stop material is installed between the two parts of the lining plate, and the two lining plates are clamped by the dovetail groove. A set of telescopic units 3, rotating parts 6 and disassembly and assembly units 5 are installed on the slide 2 again, so that the two prefabricated reinforced concrete lining plates correspond to a set of disassembly and assembly units 5 respectively, and threaded sleeves are prefabricated on the two prefabricated reinforced concrete lining plates respectively, and the locking device 502 is started, and the self-tapping bolts 503 automatically fed are screwed into the threaded sleeves, and the corresponding lining plates are fixed on the mounting frame 501. The lining plate is moved to the designated position and below by the slide 2 to complete the installation.

[0060] Specifically, Figure 4 As shown, the mounting plate 602 is provided with a plurality of mounting screws 604, and the plurality of mounting screws 604 are all threadedly connected with nuts 603; when the cutting unit 4 and the disassembly unit 5 are replaced, the mounting screws 604 and nuts 603 are used to facilitate the disassembly and assembly of the two, thereby reducing the time for changing the machine on shore. In some other embodiments, two slides 2 may also be used. After the first slide 2 carries the cutting unit 4 to cut the lining plate, the first slide 2 may be controlled to slide to the bottom of the truss 1, i.e., the water-entering end of the truss 1, to provide a completed working surface for the second slide 2. This workflow does not require the cutting unit 4 and the disassembly unit 5 to be disassembled.

[0061] Specifically, Figure 2 As shown, the slide 2 includes two suspension rods 201 arranged on both sides of the truss 1 and a carrier frame 301 connecting the two suspension rods 201, the top end of the suspension rod 201 is bent inward to form a bending portion 202, the bending portion 202 is provided with a first driving wheel 203, the truss 1 is provided with a first track 204, and the first driving wheel 203 is rollingly connected to the first track 204; in order to ensure the smoothness of the movement of the slide 2 on the truss 1, the bending portion 202 formed by the suspension rod 201 is hooked on the truss 1, and the first driving wheel 203 is rollingly connected to the first track 204 on the truss 1, which can improve the smoothness of the movement of the slide 2 on the truss 1. At the same time, a driving source, such as a motor drive, can be added to the first driving wheel 203, and the external hoisting can be cancelled. The first driving wheel 203 is controlled to rotate by the driving source to realize walking, and the first driving wheel 203 and the first track 204 can be matched with a gear rack to ensure that the position will not change after stopping due to the influence of water flow.

[0062] Specifically, Figure 3As shown, both sides of the carrier 301 are provided with slide grooves 306, and both sides of the fixed frame 302 are rotatably provided with second driving wheels 307, the inner side of the slide grooves 306 is provided with second tracks 308, and the second driving wheels 307 are rollingly connected with the second tracks 308; in order to ensure the smoothness of the telescopic unit 3 on the slide 2, with the cooperation of the second driving wheel 307 and the second track 308, the friction of the telescopic unit 3 during movement can be reduced, and at the same time, a driving source can be added to the second driving wheel 307, such as a motor drive, and the second driving wheel 307 can be controlled to rotate by the driving source to realize walking. The second driving wheel 307 and the second track 308 can also adopt a gear rack matching structure to ensure that the position after stopping will not change.

[0063] like Figure 1 As shown, it also includes a walking unit 7, which includes two walking frames 701 arranged at the water inlet end and the water outlet end of the truss 1, and the two walking frames 701 are both provided with a third driving wheel 702; when the lining plate covered by the truss 1 is repaired, the third driving wheel 702 can be used to walk on the channel bottom and channel bank to drive the truss 1 to change the working position in the river channel or channel, thereby realizing a large number of lining plate repair operations.

[0064] The present invention also provides a method for repairing a concrete lining plate under flowing water, comprising the above-mentioned equipment for repairing a concrete lining plate under flowing water, and further comprising the following steps:

[0065] S1: truss 1 forming and construction positioning, transporting the prefabricated truss segments to the channel or river repair site, assembling and positioning the truss 1 segments on the shore platform to form a truss 1 structure, and then hoisting the truss 1 into the water through hoisting equipment;
