Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water conservancy projects, in particular to a reservoir dam overflow surface damage repairing device. BACKGROUND

[0002] After long-term operation of the reservoir dam, due to the influence of the construction technology and the concrete strength at that time, most of the overflow surface will be damaged, such as erosion, honeycomb, joint falling off, etc., and usually a grouting machine is needed to repair the damaged area.

[0003] When the overflow surface of the reservoir dam has erosion pits that need to be repaired, the damaged concrete range profile to be cleaned is usually first outlined, and then a concrete cutting machine is used to cut grooves. Then, small electric tools or light tools are used to remove loose concrete, and large equipment is used as little as possible or not at all to avoid disturbing and damaging the integrity of the surrounding concrete. After that, the base surface dregs, dust, and oil stains, moss, etc. are washed clean. After the base surface is dry (moisture content is not more than 8%), two coats of small molecule primer are applied. After the primer is dry, a grouting machine is used for grouting (the grouting material is prepared according to factors such as the depth and size of the erosion pit).

[0004] When the area of the erosion pit is large, the time needed for grouting repair is also long, so the construction personnel need to control the grouting machine to temporarily stop at the periphery of the erosion pit. At this time, the grouting machine needs to maintain the function of continuous and stable grouting, and at the same time, it needs to ensure that the grout uniformly fills the erosion pit and prevents foreign matter from being mixed in, so as to ensure the repair quality after the subsequent grout solidifies.

[0010] Optionally, the flushing assembly further comprises a water conveying valve for controlling whether the water conveying pipe communicates with the fixed tube, and the water conveying valve is located at the position of the fixed tube close to the slurry tank.

[0011] By adopting the above technical scheme, the construction personnel can conveniently select the flushing assembly according to the needs, reduce the influence of the flushing assembly on the grouting process, and effectively increase the flushing range of the flushing assembly to the internal space of the fixed tube.

During the grouting repair process, the ball will be affected by the operation of the grouting component and will roll back and forth in the moving groove. The force exerted by the ball on the frame will drive the frame to move gradually towards the lower inclined position, thereby achieving more uniform grouting in the erosion pit and eliminating the trouble of manually operating the frame to change the grouting position.

[0024] Optionally, grouting repair is performed with the vehicle body positioned above the erosion pit at an angle, and the baffle located between the vehicle body and the erosion pit is applied.

In this embodiment, the length of the baffle plate 5 is preferably greater than the length of the erosion pit 11, and when the abutting surface 51 of the baffle plate 5 adjacent to the erosion pit 11 is in contact with the overflow surface 1, the two ends of the abutting surface 51 in the length direction are respectively located on the two sides of the erosion pit 11; and the bottom of the baffle plate 5 is preferably made of rubber material.

[0050] With reference to Figure 1 and Figure 2 In this embodiment, the driving structure 22 preferably includes a rotating arm and a servo motor.

Since the driving structure 22 having the above functions is a common prior art, it will not be described here, and only a brief representation thereof is shown in the drawings.

[0051] During the movement of the baffle plate 5 driven by the driving structure 22, the abutting surface 51 of the baffle plate 5 can remain in the position on the bottom of the baffle plate 5 under the action of its own gravity; when the servo motor drives the rotating arm to rotate upward to the limit position, the baffle plate 5 maintains a spacing with the overflow surface 1; when the servo motor drives the rotating arm to rotate downward to the limit position, the abutting surface 51 of the baffle plate 5 will abut against the overflow surface 1, and the rotating freedom of the baffle plate 5 relative to the rotating arm can make it adaptively rotate until the abutting surface 51 abuts against the overflow surface 1 and presses downward on the overflow surface 1.

During the grouting repair process, the device as a whole is affected by vibration due to the operation of the stirring structure 32 and the grouting pump 44. At this time, the rolling ball 9 will reciprocally roll in the movable groove 71 under the influence of vibration, and the impact on the inner wall of the movable groove 71 during the reciprocating rolling process has a tendency to drive the frame body 7 to move relative to the baffle 5.

[0055] The implementation principle of the reservoir dam overflow surface damage repair device according to the embodiment of the application is as follows: Before the erosion pit 11 on the overflow surface 1 needs to be repaired, the proportioned and sufficient grouting material is poured into the storage space, and sufficient flushing water is poured into the cavity of the water storage tank 61, then the vehicle body 2 is controlled to move to the surrounding of the erosion pit 11, and then the abutting surfaces 51 of the three baffles 5 are controlled to be in close contact with the overflow surface 1, so that the vehicle body 2 is positioned on the overflow surface 1; Then the erosion pit 11 is grooved, the water delivery valve 64 and the lower delivery valve 45 are opened, the upper delivery valve 45 is closed, and then the water delivery pump 63 is controlled to be opened, so that the erosion pit 11 is flushed by the construction personnel holding the discharge nozzle 43, and the inside of the grooved erosion pit 11 is kept clean; After the inside of the erosion pit 11 is dried, the vehicle body 2 is moved to one side above the inclined side of the erosion pit 11, and then the abutting surfaces 51 of the three baffles 5 are controlled to be in close contact with the overflow surface 1, so that the vehicle body 2 is positioned. At this time, the baffle 5 close to the erosion pit 11 is located between the erosion pit 11 and the vehicle body 2, and effectively prevents impurities on the overflow surface 1 from entering the erosion pit 11 under the action of gravity. Before grouting repair, the discharge nozzle 43 is installed on the frame 7 near the erosion pit 11, the water delivery valve 64 is closed and the two delivery valves 45 are opened, then the slurry pump 44 is controlled to be opened, so that the slurry in the slurry storage space 311 is driven to flow into the erosion pit 11 through the fixed pipe 41, the movable pipe 42 and the discharge nozzle 43 in turn, and is uniformly dispersed under the flow uniformization of the flow uniformization surface 52, and the stirring structure 32 keeps stirring the slurry in the slurry storage space 311 during the process; Specifically, when the erosion pit 11 has a certain inclination on the overflow surface 1, before grouting repair, the positions of the two limit members 8 on the top of the baffle 5 are determined, so as to limit the activity range of the frame 7, then the frame 7 is moved to the inclined upper end before grouting repair, at this time, the rolling ball 9 is rolled in the movable groove 71 under the influence of vibration, and the force applied to the frame 7 by the rolling ball 9 drives the frame 7 to tilt downward in the allowed activity range under the action of its own gravity, so that the grouting position gradually changes, thereby improving the efficiency and effect of grouting, and reducing the waste of slurry overflow; Specifically, when the erosion pit 11 is relatively neat on the overflow surface 1 (for example, the length direction is parallel or perpendicular to the inclination direction of the overflow surface 1), before grouting repair, only the two limit members 8 are needed to limit the activity of the frame 7 relative to the baffle 5, and the frame 7 is centered on the top position of the baffle 5, and the discharge nozzle 43 installed on the frame 7 is centered relative to the length direction of the erosion pit 11, so as to perform grouting repair; After grouting repair, during the process of solidification of the slurry, the construction personnel can keep the current position state of the vehicle body 2 according to the situation, at this time, the baffle 5 can still play the effect of preventing impurities from entering above the erosion pit 11; or the vehicle body 2 is controlled to move away from the erosion pit 11, and the flow uniformization surface 52 of the baffle 5, the inside of the fixed pipe 41, the inside of the movable pipe 42 and the inside of the discharge nozzle 43 are flushed by means of the flushing assembly 6 and the delivery assembly 4, so as to facilitate the next use.

[0056] The above are preferred embodiments of the present application, and are not used to limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
