Description

Technical Field

[0001] The invention relates to the technical field of asphalt pavement crack repair and reinforcement devices, and in particular to a portable asphalt pavement crack repair and reinforcement device and a repair method thereof. Background Art

[0002] During the design service life of asphalt concrete pavement, under the conditions of repeated rolling under cyclic loads, temperature changes, shrinkage of the base layer, etc., cracks of varying sizes will inevitably appear on the surface asphalt layer, including transverse cracks, longitudinal cracks, and mesh cracks. Asphalt cracks are divided into two types according to their causes: load-type cracks and non-load-type cracks. Non-load-type cracks are further divided into shrinkage cracks of the asphalt surface layer and reflection cracks of the base layer. Among them: load-type cracks are caused by tensile stress exceeding the fatigue strength of the material and develop from bottom to top; shrinkage cracks of the asphalt surface layer are caused by the stress generated by the shrinkage of the asphalt material in winter being greater than the material strength; reflection cracks of the base layer are caused by the extension of the shrinkage cracks of the base layer to the asphalt surface layer, including the "white to black" composite asphalt pavement structure formed by adding an asphalt surface layer to the old cement concrete road slab. Since stress concentration is prone to occur at the joints and cracks of the cement concrete, it is very easy to cause reflection cracks in the asphalt surface layer.

[0003] At present, the grouting method is often used to repair cracks in asphalt pavement. First, the dust and impurities in the cracks are blown away with a dust removal machine, and then asphalt waterproof coating, polyurethane waterproof coating, organic silicone cold caulking glue, polyurethane high-strength resin potting glue, hot asphalt potting glue or emulsified asphalt solution and other caulking solutions are injected into the asphalt cracks, embedded in the cracks and solidified into shape, so as to achieve the purpose of repairing cracks in asphalt pavement. Traditional asphalt crack repair equipment is mostly a tank body. The caulking repair solution in the tank body is injected into the crack through the tank body drainage equipment process. Because the tank body is bulky and inconvenient to move during construction, it is usually placed on a cart or tricycle, which requires the operator to While moving the cart, aim the nozzle equipment extending from the tank at the asphalt cracks. The process is not flexible enough, the process is complicated, the operation is troublesome, the quality of the grouting is difficult to guarantee, the construction work surface is large, the work efficiency is low, and before the grouting and repairing solution is filled, the dust and impurities in the asphalt cracks need to be cleaned by a dust removal and cleaning machine to prevent the dust from forming an isolation layer between the crack surface and the grouting and repairing solution, affecting the bonding strength and stability. The process operation steps are cumbersome, which brings many inconveniences to the operator. Moreover, the dust blown away by the dust removal and cleaning machine spreads in the air, which not only pollutes the environment, but also easily enters the body through breathing by the operator, posing a health hazard to the body. The patent document with application number 202410791791.8 discloses a rapid repair device and repair method for cracks in asphalt pavement. It discloses the technical solution of placing the above-mentioned barrel on a cart. The barrel is bulky, the construction operation is inconvenient to move, and the dust in the surface of the crack cannot be handled. Summary of the invention

By providing the buckle 6, the suction component 3, the jet component 4 and the spray component 5 are bundled together, which is convenient for the operator to hold the handle and work.

[0060] Furthermore, the present invention also provides a repair method based on any of the above-mentioned portable asphalt pavement crack repair and reinforcement devices, comprising the following steps:

[0061] S1: Aim the jet assembly (4) at the asphalt cracks, and the dirty gas enters the air filter chamber (21) through the suction assembly (3). The dirty gas is filtered and then ejected through the jet assembly (4), blowing away the dust in the asphalt cracks. The blown dust gas is sucked into the suction assembly (2), thereby forming a circulating airflow to clean the asphalt cracks;

[0062] S2: Start the reflux pump (231), which transports the caulking solution from the lowest point of the bottom wall of the silo (1) along the spraying assembly (5) and injects it into the asphalt cracks, thereby starting to repair the asphalt cracks.

[0063] Specifically, the repair method of the portable asphalt pavement crack repair and reinforcement device comprises the following steps:

[0064] When in use, after injecting the caulking solution into the storage silo 1 through the equipment injection port 11, the operator carries the silo 1 on his back with a breathable shoulder strap, holds the stainless steel telescopic spray rod handle with his right hand, aims the spray nozzle 45 of the spray core rod 43 at the asphalt crack, and turns on the fan power switch 223 in the electric control panel 222 with his left hand to turn on the fan 211. The dirty gas is sucked into the air duct from the suction hood head 35 at the end of the suction rod 33, and enters the air filter chamber 21 through the suction check valve 34 from the suction hose 32 from the suction inner tube 31, and then passes through the large-pore air filter 214, the medium-pore air filter 215, and the micro-pore air filter 216 in sequence, and then passes through the left side of the air filter chamber 21 through the suction check valve 34. The jet check valve 44 enters the jet inner tube 41, and the clean gas that has filtered out the dust is ejected from the jet nozzle 45 along the gas pipeline to blow away the dust in the asphalt cracks. The blown dust is covered by the suction hood head 35 and then sucked into the suction rod 33. In this cycle, dust of different particle sizes are blocked by air filters of different apertures and accumulated in the filter residue collection drawer 212. The filter residue collection drawer 212 can be taken out for easy dust cleaning and filter replacement. The jet nozzle 45 ejects clean gas and the suction hood head 35 sucks the blown dirty gas to form a circulating airflow, thereby avoiding dust flying around to cause air pollution and affect health.

[0065] The right hand squeezes the power switch 55 of the speed control handle to start the reflux pump 231. The reflux pump 231 transports the grouting solution from the lowest point of the bottom wall of the silo 1 along the spray hose 51 and the spray rod 52 to the material nozzle 53, and then injects it into the asphalt cracks, thereby starting to repair the asphalt cracks. At this time, the operator carries the silo 1 on his back and holds the stainless steel rod handle with his right hand, relying on the guide wheel 36 to move the equipment pipeline along the direction of the asphalt cracks. At this time, the front jet nozzle 45 cleans the dust and impurities in the asphalt cracks, the rear material nozzle 53 repairs the asphalt cracks, and the leveling baffle 54 automatically levels and reinforces. Cleaning the asphalt cracks and repairing and reinforcing the asphalt cracks are carried out simultaneously, and the two are arranged at intervals and do not interfere with each other, forming a cyclic process. There is no need to set up an additional dust removal and cleaning machine, nor is there any need to move the tank placed on the cart or tricycle. The process is simple, the production cost is reduced, and the operator's work intensity is reduced. Compared with the traditional asphalt crack cleaning technology of cleaning first and then repairing, this equipment will clean and repair at the same time, simplify the crack repair steps, and be more flexible and convenient to operate, thereby improving the efficiency of asphalt crack repair.
