Technical Field

[0001] This invention belongs to the technical field of grouting hole treatment equipment, specifically a rapid cleaning device for grouting ports. Background Technology

[0002] Currently, grouting is widely used in construction, coal mining and other fields. The formation of grouting holes involves drilling holes to inject grout, which can fill cracks and pores in rock and soil, prevent foundation leakage, and improve the integrity, strength and rigidity of rock and soil. At present, broken rock fragments remain in the holes after the grouting holes are formed. If they are not cleaned in time, they can easily cause missing grout at the corners, extended cracks or even faults during subsequent grouting. In the existing technology, they are mostly removed by spiral drill rods. However, spiral drill rods have high limitations and low cleaning effect in cleaning large-diameter grouting holes.

[0003] Therefore, those skilled in the art have provided a rapid cleaning device for grouting ports to solve the problems mentioned in the background art. Summary of the Invention

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0021] Please see Figure 1 In this embodiment of the invention, a rapid cleaning device for grouting ports includes: an embedded ring seat 12, which is embedded and fixed in the grouting hole 1 at the hole opening position. A side hole 2 is vertically formed on one side of the grouting hole 1. The inner diameter of the side hole 2 is smaller than the diameter of the grouting hole 1, and the depth of the side hole 2 is greater than half the depth of the grouting hole 1. A vibrating hole assembly 4 is provided in the embedded ring seat 12. The vibrating hole assembly 4 can slide into the grouting hole 1. A channel 11 is provided laterally between the side hole 2 and the grouting hole 1. There are two channels 11 arranged vertically. A circulation drainage assembly 3 is also provided in the side hole 2.

[0022] In this embodiment, each of the channels 11 is opened at a corresponding upper or lower position one-fifth of the length of the grouting hole 1. The grouting hole 1 is also connected to a water supply pipe. That is, water is injected into the grouting hole 1 through the water supply pipe, so that it is higher than the channel located above. At this time, in conjunction with the circulation drainage component 3, the water flow can circulate between the grouting hole 1 and the side drill hole 2, thereby achieving the cleaning effect of the grouting hole 1. Compared with opening a drainage trough, the circulation drainage component in this invention can effectively reduce water waste while ensuring the cleaning effect.

[0023] In a preferred embodiment, the vibrating hole assembly 4 includes: a limiting guide bar 41, which is symmetrically and vertically slidably disposed on the embedded ring seat 12; a first vibrating hole device 5 is fixed below the limiting guide bar 41; a transmission screw 42 is vertically fixed at the center of the first vibrating hole device 5; a threaded sleeve is rotatably disposed inside the embedded ring seat 12; one end of the transmission screw 42 is slidably connected to the threaded sleeve through threaded engagement; a second vibrating hole device 45 is disposed below the first vibrating hole device 5; the first vibrating hole device 5 is fixed to the second vibrating hole device 45 through an intermediate column 43; that is, the threaded sleeve drives the transmission screw to slide vertically under rotation, thereby adjusting the mounting positions of the first and second vibrating hole devices.

[0024] In this embodiment, the first vibrating hole device 5 and the second vibrating hole device 45 have the same structure and both include: a shaft plate seat 51, a plurality of side supports 52 are distributed circumferentially on the shaft plate seat 51, each of the side supports 52 is synchronously slidably connected to the shaft plate seat 51, an inner shaft cylinder 53 is vertically fixed in the shaft plate seat 51, a connecting plug is slidably disposed in the inner shaft cylinder 53, and sliding rods 55 are symmetrically fixed outside the inner shaft cylinder 53, with vibration elements 56 slidably disposed on the sliding rods 55. The vibrating element is fixed to the inner shaft cylinder 53. A carrier plate is fixed on the shaft plate seat 51 below the sliding rod 55. An outer spring is sleeved on the sliding rod 55. One end of the inner shaft cylinder 53 is connected to a pulse pump (not shown in the figure). A side stop 54 is also circumferentially embedded on the inner shaft cylinder 53. Under continuous air supply and pressure, the pulse pump can form an impact on the carrier plate through the vibrating element, and the side supports can transmit vibration to the grouting hole 1, thereby realizing the detachment of the broken rock on the hole wall.

[0025] In this embodiment, the intermediate column 43 is externally rotatably sleeved with a flow guide 44. The flow guide 44 can rotate alternately in both directions, and the blades on the flow guide 44 are inclined at 45°. After the grouting hole 1 is filled with water, the circulation drainage component 3 can guide the water flow from top to bottom. On the one hand, when the flow guide 44 rotates in the forward direction, the blades on the flow guide the water flow in the same direction, thereby forming a flow promotion effect, improving the water flow in the early stage of hole cleaning, and facilitating the transportation of broken blocky rocks with large outer diameters. When the water flow completes n cycles (n>5) between the grouting hole and the side borehole, the flow guide 44 rotates in the reverse direction, forming a flow obstruction effect on the water flow. At this time, the water flow diffuses from the hole wall of the grouting hole, which can effectively wash the hole wall thoroughly.

[0026] In this embodiment, the circulating drainage assembly 3 includes two sealing support plates 31, one above the other. Each sealing support plate 31 is sealed and embedded within the side borehole 2 and located between the channels 11, thus dividing the side borehole into three independent chambers. The sealing support plates 31 are connected and fixed together. A guide seat 32 is vertically fixed within the lower sealing support plate 31. Drainage fan blades 33 are rotatably disposed within the guide seat 32, and these fan blades can guide the water flow from bottom to top within the side borehole during rotation. A flow-carrying pipe 34 is vertically fixed inside the sealing support plate 31 located above. A conveying pipe 38 is vertically and symmetrically connected to the flow guide seat 32. One end of the conveying pipe 38 is connected to the flow-carrying pipe 34. The flow-carrying pipe 34 is provided with multiple flow holes, and a filter cartridge seat 35 is also sleeved around the flow-carrying pipe 34. This can effectively filter the broken rocks in the water flow and prevent them from entering the grouting hole. Especially in the initial hole cleaning, rocks with larger outer diameters fail to enter the flow guide seat and instead remain in an independent chamber at the lower part of the side borehole.

[0027] In a preferred embodiment, the flow guide seat 32 is provided with a plurality of drainage holes, each of which is connected to the delivery pipe 38. A ball shaft 39 is inclinedly arranged in the flow guide seat 32 by means of a support spring. The ball shaft 39 can seal and block the drainage holes, thereby realizing unidirectional water flow and avoiding backflow.

[0028] In this embodiment, an external pipe 36 is provided inside the side borehole 2. The external pipe 36 is fixed to the flow-carrying pipe 34, and a drain pipe 37 is connected below the external pipe 36. In particular, after the grouting hole is cleaned, the water flows out through the drain pipe.

[0029] Specifically, a side borehole is drilled on one side of the grouting hole. The side borehole is connected to the grouting hole through a channel. The vibrating hole assembly prioritizes internal vibration of the grouting hole. At the same time, the water supply pipe injects water into the grouting hole and completely submerges the channel. At this time, the drainage fan blades in the circulation drainage assembly rotate to realize the water flow circulation between the grouting hole and the side borehole, thereby realizing the cleaning of the grouting hole. In addition, the forward and reverse rotation of the guide blades further improves the cleaning effect. After the cleaning is completed, the water flow is discharged through the drain pipe.

[0030] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
