Description

Technical Field

[0001] The present invention relates to the technical field of road repair, and in particular to automatic drilling and grouting equipment and a method for using the same. Background Art

[0002] Semi-rigid base asphalt pavements account for a significant portion of my country's expressways. However, over extended use, the strength and bearing capacity of these pavements gradually weaken due to fatigue damage caused by environmental factors such as temperature, moisture, and repeated loads. Furthermore, coupled with factors such as heavy loads and high temperatures, these conditions accelerate the deterioration of the semi-rigid base pavement, generating numerous cracks that are then reflected in the pavement surface. This not only compromises the structural integrity and continuity of the pavement, adversely affecting its durability, but also damages the pavement's waterproofing system. Ultimately, this reduces the pavement's bearing capacity and adhesion to the surface layer, leading to the development of a network of cracks in the surface layer, exacerbating damage to the asphalt pavement and shortening its lifespan.

[0003] Currently, the following methods are commonly used in my country to treat reflective cracks in semi-rigid asphalt pavements: applying anti-crack patches, overlaying, excavation repair, and crack caulking, either singly or in combination. However, these technologies typically only treat the surface of the asphalt pavement, rarely reaching the semi-rigid base. Consequently, none of these methods address the cracks fundamentally. Furthermore, under the influence of vehicle loads and environmental factors, cracks in the semi-rigid base gradually widen and multiply, ultimately increasing the severity of asphalt concrete pavement problems and compromising the pavement's serviceability and driving safety.

[0004] With the development of economy and technology, and the improvement of equipment, trenchless grouting technology has gradually developed for the treatment of cracks in semi-rigid base layers. For example, patent number CN213221836U discloses an automatic feeding grouting device, and patent number CN209586264U discloses an asphalt pavement grouting drilling device. These devices can respectively realize automatic slurry feeding and pouring, and automatic hole drilling. However, during the construction process, the treatment of cracks in semi-rigid base layers requires multiple processes such as drilling, cleaning, and grouting, and requires the cooperation of multiple sets of equipment. This greatly increases the complexity of the construction and is not conducive to the automated, precise, and rapid repair of pavement cracks.

[0005] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art known to those skilled in the art.

The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0056] like Figures 1 to 11 The automatic drilling and grouting equipment shown includes:

[0057] A frame 10 and a mixing mechanism fixed on the frame 10;

[0058] The mixing mechanism includes a batching component 21 and a storage component 22. The batching component 21 includes a stirring tank 211 and an agitator 212. The stirring tank 211 is fixed to the frame 10. The agitator 212 is located in the cavity of the stirring tank 211 and is rotatably connected to the stirring tank 211. The storage component 22 includes a slurry storage tank 221, which is connected to the stirring tank 211. The epoxy resin main agent 01 and the curing agent 02 enter the stirring tank 211, are evenly mixed by the agitator 212, and form a binder 03, which is sent to the slurry storage tank 221 for use.

[0059] Among them, a drilling mechanism 30, a cleaning mechanism and a grouting mechanism 50 are also provided on one side of the direction of travel of the frame 10. The drilling mechanism 30, the cleaning mechanism and the grouting mechanism 50 are detachably connected to the frame 10 through corresponding protective mechanisms; each protective mechanism includes a protective cover 61 and a pulley 62, the protective cover 61 is trumpet-shaped, the contraction end is detachably connected to the frame 10, and the other end is arranged toward the ground, the pulley 62 is rotatably connected to the protective cover 61 and contacts the ground; the drilling mechanism 30 includes a spiral drill bit 31. The spiral drill bit 31 is arranged in the protective cover 61, and the axis is arranged perpendicular to the ground, and is used to drill a hole at a specified position on the crack; the cleaning mechanism includes a dust suction component 41 and a drying component 42, the dust suction component 41 is used to suck out the dust in the hole, and the drying component 42 is used to keep the hole dry; the grouting mechanism 50 includes a grouting pipe 51, one end of the grouting pipe 51 is connected to the slurry storage tank 221, and the other end is arranged toward the hole, and is used to deliver the binder 03 in the slurry storage tank 221 into the hole.

[0060] It should be noted that the protective cover 61 has different effects in different working stages. When the drilling mechanism 30 is working, a certain amount of dust will be generated during drilling, and the protective cover 61 can effectively prevent the dust from floating up to avoid pollution; when the cleaning mechanism is working, the dust cover can effectively ensure that the dust in the hole can enter the dust suction component 41 and will not fly around with the operation of the cleaning mechanism; during the operation of the grouting mechanism 50, the protective cover 61 effectively prevents the binder 03 from splashing out around the hole, thereby reducing the impact on the environment during the road repair process.

[0061] The present invention detachably connects the drilling mechanism 30, the cleaning mechanism and the grouting mechanism 50 to the frame 10 through corresponding protective mechanisms, thereby realizing the integration of various construction equipment, improving the speed and efficiency of road crack repair, and realizing the automated, precise and rapid repair of cracks; the curing is basically completed in 5 minutes, and the strength can reach more than 90% of the final strength. Under the pressure of the grouting mechanism 50, the binder 03 is squeezed into the deep of the crack to fully penetrate the crack. At the same time, the material has high-strength active groups, which can react quickly with the active hydrogen of the base layer to form better bonding properties. It can also meet the demand of opening traffic within 2 hours, thereby realizing the deep-level rapid repair of cracks and improving the properties of the road structure plate.

[0062] On the basis of the above embodiment, an operating mechanism is further provided on one side of the frame 10 in the backward direction, and the operating mechanism includes an operating panel 72 and a handle 71;

[0063] The handle 71 and the operating panel 72 are fixedly connected to the frame 10 . The handle 71 is used by the operator to support and control the movement of the frame 10 , and the operating panel 72 controls the operation of the mixing mechanism, the drilling mechanism 30 , the cleaning mechanism and the grouting mechanism 50 .

[0064] It should be noted that the operating panel 72 can also monitor and reflect the working status of the mixing mechanism, drilling mechanism 30, cleaning mechanism and grouting mechanism 50 in real time, using GPRS wireless transmission, such as monitoring the mixing time, heating time, heating temperature, pumping time and pressure of the mixing mechanism; monitoring the depth and intensity of the drilling of the drilling mechanism 30; monitoring the wind force, direction, time, etc. of the cleaning mechanism; monitoring the grouting pressure of the grouting mechanism 50, the expansion degree of the cracks, the fullness of the grouting, etc.; thereby ensuring the precise operation of the automatic drilling and grouting equipment and ensuring the quality of road repair.

[0065] Based on the above embodiment, the batching assembly 21 further includes an input pipe 213, an output pipe 214, an isolation plate 215, a heating pipe 216 and a fixing plate 217;

[0066] The input pipe 213 is connected to the top of the stirring tank 211, the output pipe 214 is connected to the bottom side wall of the stirring tank 211, the isolation plate 215 and the bottom of the stirring tank 211 surround to form a closed space, the heating pipe 216 is located in the closed space and is fixedly connected to the inner side wall of the isolation plate 215 through the fixing plate 217.

[0067] In the process of road repair, water-resistant modified polyurethane reactive materials are usually used for repair, which have the characteristics of good permeability, high strength and fast molding. The slurry preparation ratio is generally: double-liquid grouting A component: B component = 1:1, wherein A component is the main agent, which is composed of composite polyol, catalyst, uniform foaming agent and toughening agent, and B component is curing agent 02PAPI-2; in the batching process, the external epoxy resin main agent 01 and curing agent 02 are fed into the mixing tank 211 from the delivery pipe according to the mass ratio of 1:1 through the pumping system, and under the action of the stirrer 212 and the heating pipe 216, the epoxy resin main agent 01 and the curing agent 02 are fed into the mixing tank 211 through the pumping system according to the mass ratio of 1:1. Under this condition, the epoxy resin main agent 01 and the curing agent 02 can be fully mixed to form a binder 03. The isolation plate 215 can effectively prevent the epoxy resin main agent 01 and the curing agent 02 in the stirring tank 211 from entering the closed space, avoiding affecting the normal operation of the heating tube 216. At the same time, the heat generated by the heating tube 216 can be transferred to the stirring tank 211 along the isolation plate 215 to ensure the normal progress of the reaction process. Under normal circumstances, the height of the isolation plate 215 is set to 1 / 3 to 2 / 3 of the height of the stirring tank 211 cavity, and the heating temperature is 60°C, which effectively ensures the overall heating.

[0068] The stirring tank 211 is surrounded by a heat-insulating layer to reduce the temperature loss of the material, and a protective layer is provided outside the heat-insulating layer to prevent the external environment from affecting the reaction in the stirring tank 211 .

[0069] Based on the above embodiment, the storage assembly 22 further includes a motor 222, a gear pump 223, a flow meter 224, a regulating valve 225 and a stop valve 226;

[0070] The gear pump 223, flow meter 224, regulating valve 225 and stop valve 226 are all arranged on the output pipe 214. The motor 222 is fixed on the frame 10 and connected to the gear pump 223. It is used to drive the binder 03 in the mixing tank 211 along the output pipe 214 into the slurry storage tank 221. The flow meter 224 is used to monitor the flow in the output pipe 214 in real time. The regulating valve 225 is used to adjust the transmission speed of the binder 03. The stop valve 226 controls the start and end of the transmission of the binder 03.

[0071] In this embodiment, the gear pump 223 transfers the fully heated and mixed epoxy resin binder 03 into the slurry storage tank 221 at a certain flow rate, and adopts the Corie mass flowmeter 224 for measurement. By adopting the digital analysis technology, the collected flow signal can be converted into digital information in a relatively short time, and the signal collection range can be expanded. It can also identify weak signals and measure the mass, temperature, density and other information of the binder 03 in the output pipe 214 in real time. The accuracy can generally reach 0.1% to 0.2%, and the repeatability is better than 0.1%.

[0072] Among them, scale lines are set on the tank body of the liquid storage tank to determine the storage amount of binder 03 in the liquid storage tank.

[0073] On the basis of the above embodiment, the mixing mechanism further includes a circulation component 23, and the circulation component 23 includes a circulation pump 231 and a circulation pipe 232;

[0074] A circulation inlet 232a and a circulation outlet 232b are respectively provided at both ends of the circulation pipe 232. The circulation inlet 232a is connected to the bottom of the mixing tank 211, and the circulation outlet 232b is connected to the top of the mixing tank 211. The circulation pump 231 is set on the circulation pipe 232, and is used to drive the binder 03 in the mixing tank 211 into the circulation pipe 232 from the circulation inlet 232a, and then return to the mixing tank 211 from the circulation outlet 232b.

[0075] In order to fully stir and mix evenly, a circulation component 23 is set to heat the epoxy resin main agent 01 and the curing agent 02 in a circulating flow state, ensuring that the heating process of the material is more uniform. At the same time, the circulated binder 03 enters the mixing tank 211 again for stirring, which also ensures the uniformity of mixing between the materials.

[0076] On the basis of the above embodiment, the drilling mechanism 30 further includes a telescopic rod 32 and a sensing piece 33;

[0077] One end of the telescopic rod 32 is fixed to the inner side of the protective cover 61 , and the other end is connected to the spiral drill bit 31 . The sensor piece 33 is set at the free end of the spiral drill bit 31 and moves with the movement of the spiral drill bit 31 to monitor the drilling condition of the spiral drill bit 31 .

[0078] Before drilling, the crack conditions should be monitored and the hole positions should be set according to the crack conditions. For crack-type defects, holes should be arranged in a "1" shape. The distance between adjacent holes can be a set distance, such as arranging a hole at intervals of 0.35m. Holes can also be arranged at equal intervals according to the length of the crack, so that the cracks are evenly filled after the binder 03 is poured, ensuring the quality of repair; the sensor piece 33 can monitor the drilling condition of the spiral drill bit 31 at any time. For example, when the spiral drill bit 31 is about to hit the steel plate or other structural layer, the sensor piece 33 will transmit the induced electrical signal to the operating panel 72, and the operating panel 72 will immediately control the drilling device to stop running, effectively protecting the safety of the steel plate and other structures.

[0079] Based on the above embodiment, the dust collecting assembly 41 includes an air outlet pipe 411, a fan 412 and an dust storage tank 413;

[0080] The air outlet 411 is respectively provided with an air intake port 411a, an air exhaust port 411b and a collecting port 411c. One end of the air intake port 411a is provided in the protective cover 61, and the air intake port 411a is provided toward the ground. The air exhaust port 411b and the collecting port 411c are located outside the protective cover 61. The fan 412 is provided at the air exhaust port 411b. The collecting port 411c is connected to the ash storage tank 413. The axes of the air exhaust port 411b and the collecting port 411c are located on the same vertical line.

[0081] After the drilling is completed, some dust, waste, water vapor, etc. will inevitably appear in the hole, and the hole needs to be cleaned to ensure the effect of grouting; the fan 412 is driven to rotate to absorb the adherent dust, capillary water, etc. inside and outside the hole, and the flowing wind is generated through the air outlet pipe 411 to suck the dust and water molecules upward from the air intake 411a, and the wind is discharged upward at the exhaust port 411b, and the dust and water molecules enter the ash storage tank 413 downward under the action of gravity, wherein the ash storage tank 413 can be a box-shaped structure or a bag-shaped structure, and there is no specific restriction here, as long as it can be connected to the collection port 411c; the closed environment formed by the protective cover has a gathering and concentration effect on absorbing wind force, effectively sucking out dust and moisture in the hole.

[0082] Based on the above embodiment, the drying component 42 includes a heating wire 421 and an air inlet pipe 422;

[0083] The air inlet pipe 422 is provided with an air inlet 422a and an air outlet 422b. The air inlet 422a passes through the side wall of the protective cover 61 and is located outside the protective cover 61. The air outlet 422b is located inside the protective cover 61 and is set towards the ground. The heating wire 421 is set at the air outlet 422b.

[0084] To further ensure the cleaning effect, after the dust suction component 41 completes its work, the natural wind in the pipe is heated by blowing hot air into the pipe to form a drying effect. At the same time, under the action of wind, the remaining dust particles can also be blown out from the holes, that is, natural wind enters the protective cover from the air inlet 422a, and under the heating action of the heating wire 421, hot air is formed to enter the holes, so that the dust particles and water molecules in the holes are blown out.

[0085] On the basis of the above embodiment, the grouting mechanism 50 further includes a screw pump 52, a support leg 53 and a radar 54;

[0086] The screw pump 52 is arranged on the frame 10, and its end is connected to the slurry storage tank 221, which is used to drive the binder 03 in the slurry storage tank 221 to be injected into the hole through the grouting pipe 51. The slurry storage tank 221 is fixed on the supporting foot 53, and the supporting foot 53 is fixed on the frame 10 at an angle. The radar 54 is installed on both sides of the protective cover 61 for monitoring the expansion of the cracks and the fullness of the grouting.

[0087] Generally, the frame 10 includes a base 11, a support frame 12, a fixed bracket and a roller 14. The base 11 is arranged horizontally, the batching component 21 is arranged on the base 11, and the roller 14 is located on the side of the base 11 away from the batching component 21. The support frame 12 and the base 11 are arranged perpendicular to each other, the operating mechanism is arranged at the top of the support frame 12, and the fixed bracket is arranged at an angle to connect the top of the base 11 and the support frame 12, thereby forming an inclined surface for inclined installation. The supporting foot 53 can be arranged perpendicular to the plane where the fixed bracket is located, so that the interface of the slurry storage tank 221 after installation can be just connected to the output end of the screw pump 52 to ensure the smoothness of grouting.

[0088] It should be noted that before injecting the binder 03 into the hole, a sealing ring coated with lubricant should be pre-buried in the hole, and the sealing component should be quickly buried using an impact hammer; when the binder 03 in the slurry storage tank 221 is full, the extension degree of the crack (position and depth) is monitored by the radar 54, and based on this, the appropriate grouting pressure is selected to grout the hole. During grouting, the fullness and flow state of the grouting can also be monitored by the radar 54. For example, when the slurry is not full, the indicator light on the operation screen flashes red; when the slurry is full, the indicator light on the operation screen flashes green; at this time, the grouting mechanism 50 stops grouting, and the grouting pressure should be controlled at 0.3MPa~0.5MPa. The pressure is dynamically adjusted according to the actual grouting effect on site. After the grouting is completed, the hole is sealed with a cork to stabilize the pressure for 3~5min. It can be cured in 15min and can be opened to traffic in 2h, which has little impact on road driving.

[0089] The present invention also provides a method for using the automatic drilling and grouting equipment as described above, such as Figure 12 As shown, the following steps are included:

[0090] Move the frame 10 to the location of the crack and prepare for grouting;

[0091] Monitor the gap conditions and set the hole positions according to the gap conditions;

[0092] Install the drilling mechanism 30 and its corresponding protective mechanism on the frame 10, move the frame 10 until the spiral drill bit 31 is above the hole position, and control the spiral drill bit 31 to move downward to drill the hole;

[0093] The cleaning mechanism and its corresponding protection mechanism replace the drilling mechanism 30 and its corresponding protection mechanism and are installed on the frame 10 to suck out the dust in the hole and dry the hole gas to maintain the hole grouting environment;

[0094] Embed the sealing ring coated with lubricant into the hole and quickly bury the sealing ring with an impact hammer;

[0095] The epoxy resin main agent 01 and the curing agent 02 are controlled to enter the mixing tank 211, and after being evenly mixed by the stirrer 212, the binder 03 is formed and sent to the slurry storage tank 221 for use;

[0096] The grouting mechanism 50 and its corresponding protective mechanism replace the cleaning mechanism and its corresponding protective mechanism and install them on the frame 10, and connect the grouting pipe 51 with the grouting tank 221 to control the cementing material 03 to enter the hole. When the grouting is full, stop and remove the frame 10.

[0097] Use cork to seal the hole and stabilize the pressure for 3 to 5 minutes to restore the road surface structure.

[0098] The technical effects achieved by the operation process of this method are the same as those in the above embodiment and will not be repeated here.
