Description

Technical Field

[0001] This invention relates to the field of civil engineering construction equipment technology, specifically to an integrated intelligent device for material preparation and spraying reinforcement to improve the seismic toughness of structures and its construction method. Background Technology

[0002] In recent years, my country has a huge stock of existing concrete and masonry structures, covering buildings, bridges, tunnels, and other fields. Many of these structures have developed cracks and reduced load-bearing capacity due to their long service life, environmental erosion, and load variations. If not repaired and reinforced in a timely manner, they are highly susceptible to collapse and other disasters under extreme loads such as earthquakes, leading to significant economic losses and casualties. Therefore, the repair and reinforcement of existing structures, as well as the improvement of their seismic toughness, have become core tasks and research hotspots for ensuring the safety of urban and rural infrastructure and enhancing regional disaster prevention capabilities. Currently, the repair and reinforcement of existing structures faces the following problems:

[0003] Currently, the mainstream reinforcement materials are mainly ordinary cement-based materials. Traditional cement-based materials have slow early strength development, limited freeze-thaw resistance, and poor interfacial compatibility with old concrete substrates. In addition, these materials contain a large amount of cement clinker, which not only consumes a lot of resources but also generates significant carbon emissions.

[0004] Existing material mixing equipment suffers from problems such as lack of temperature control, poor mobility, and weak fiber processing capabilities. The lack of temperature control leads to unstable material performance under high and low temperature environments, the lack of horizontal adjustment function makes it easy for the equipment to tilt and cause uneven mixing, and the reliance on fixed power supply and wheeled chassis makes it inflexible in complex sites. Moreover, the material preparation requires manual dispersion of fibers, which is prone to problems such as clumping.

[0005] Traditional structural reinforcement methods often employ techniques such as manual plastering and on-site casting, which suffer from low efficiency and difficulty in quality control. Manual plastering relies on manual skills and is prone to hollow areas and uneven thickness; while on-site casting requires formwork and curing, which takes a long time and interferes with the normal use of the structure during the construction period, and lacks intelligent management and control methods. Summary of the Invention

[0025] This invention's device boasts advantages such as high flexibility, outstanding efficiency, controllable quality, and strong versatility. Through modular assembly and the synergistic application of intelligent control and monitoring technologies, it can achieve high-quality operation under various complex working conditions. The device includes a container module, a spraying module, a movable module, and an intelligent control module. The container module is an assembled mixing container used to process corresponding materials and complete mixing operations; it can be customized to adapt to various materials. The spraying module consists of two angle adjusters, a pressure-controlled spray nozzle, and a spray diameter adjuster. Through coarse and fine adjustment dual redirection, it controls the spraying pressure, angle, and range in real time, adapting to multi-condition, multi-directional construction. The intelligent control module uses an industrial-grade PLC as its core, equipped with a touchscreen controller and an electronic component installation area, enabling parameter presetting, command issuance, data interaction and storage, and dynamic control of the construction process through sensor linkage. The movable module adopts a tracked chassis and a hydraulic shock absorption system, supporting operation in power-free scenarios under harsh construction conditions, enabling the equipment to maintain stable operation in complex reinforcement scenarios such as tunnels and slopes where external power is lacking. This device is mainly used for the rapid repair and reinforcement of damaged structures in civil engineering fields such as buildings, bridges, and tunnels.

[0026] The reinforcement and repair material in this invention uses high-solid-waste materials as its core. While reducing environmental impact, it can also fully utilize the material's performance through the full-process control capabilities of the intelligent control module: the industrial-grade PLC-linked weighing sensor measures the feeding ratio of high-solid-waste cementitious materials, fine aggregates, and multi-scale fibers in real time, and the speed sensor dynamically adjusts the stirring speed of each propeller to ensure the synergistic enhancement effect of the three-dimensional random dispersion of flexible fibers and the directional distribution of steel fibers; at the same time, the circulating water temperature control device combined with the temperature sensor intelligently maintains the mixing temperature to avoid the impact of environmental temperature fluctuations on the material's strength development. Ultimately, it achieves a synergistic breakthrough in strength and ductility while reducing environmental impact. Moreover, the entire process parameters can be preset, data can be stored, and the effect can be monitored, forming an integrated management and control system of "material formulation - intelligent preparation - performance assurance".

[0027] This invention's device is equipped with a circulating water temperature control system and a level sensor, ensuring construction stability in high and low temperatures and uneven terrain. Utilizing a tracked chassis and lithium battery power, it is adaptable to complex construction scenarios without external power sources. It supports real-time control of mixing speed and fiber dispersion, precisely adapting to the mixing needs of various working conditions and materials, achieving intelligent control of the entire "mixing-conveying-spraying" process, significantly improving equipment adaptability and construction convenience.

[0028] This invention employs integrated spraying reinforcement technology, eliminating the need for formwork and increasing construction efficiency several times over traditional methods, significantly reducing labor costs. Simultaneously, it leverages an intelligent control module to adjust spraying pressure, angle, range, and material mixing parameters in real time, ensuring reliable construction quality. This characteristic makes the device highly advantageous for reinforcing core infrastructure such as tunnels and bridges: these facilities are critical nodes in transportation networks, and prolonged shutdowns due to construction can not only cause huge economic losses but also potentially paralyze regional traffic. This device, with its dual advantages of "intelligent control + rapid spraying," can efficiently complete reinforcement work while avoiding prolonged operational interruptions, perfectly balancing construction needs with infrastructure operational security, achieving both high efficiency and high quality.

[0063] Specific implementation method eight: Combination Figures 1 to 12 This embodiment describes a mixing tank 5 equipped with a circulating water temperature control device 17, which in turn is equipped with a temperature sensor 18.

[0064] The undisclosed technical features in this embodiment are the same as those in Specific Embodiment 1.

[0065] During the mixing process, the circulating water temperature control device 17, together with the temperature sensor 18, controls and monitors the temperature of the mixed materials in real time, avoiding the material from solidifying too quickly due to low temperature and the material performance from degrading due to high temperature, thus adapting to complex construction environments with high and low temperatures.

[0069] In the embodiments described in this invention,

[0070] The cementitious material conveying hopper 101 is used to feed cementitious materials and admixtures, and the fine aggregate conveying hopper 201 is used to feed fine aggregates. After initial mixing, the two materials enter the mixing tank 5 and are further mixed by the mixing mechanism 501. During the mixing process, the metering pump 6 adds water or alkali activator (water is added when the cementitious material contains a high amount of solid waste, and alkali activator is added when it contains all solid waste). The time is controlled so that flexible fibers are fed into the flexible fiber conveying hopper 401. After being dispersed by the flexible fiber vibrating screen 404, the fibers enter the flexible fiber conveying channel 405 for conveying. The steel fibers are on the upper part of the conveying channel. After the mixing process is completed, the material is conveyed to the steel fiber conveying channel 305 via the steel fiber conveying hopper 301. This channel is equipped with a screw with a scraper for coarse orientation, and the steel fiber rotating comb 304 is paired with a steel fiber double-layer vibrating screen 306 for fine orientation. After the mixing mechanism 501 finishes mixing, the material is controlled by the jetting power device 7 and enters the jetting nozzle 10 through the jetting pipe 8. Two angle adjusters 14 adjust the angle of the jetting pipe 8, thereby adjusting the jetting angle of the jetting nozzle 10. The jetting power device 7 can adjust the jetting pressure.

[0071] Each material conveying channel is equipped with a weighing system, consisting of a material conveying hopper, a corresponding weighing sensor, and a hinged door, to achieve intelligent weighing control.

[0072] The cementitious material conveying hopper 101, fine aggregate conveying hopper 201, steel fiber conveying hopper 301, and flexible fiber conveying hopper 401 are equipped with corresponding cementitious material weighing sensors 102, fine aggregate weighing sensors 202, steel fiber weighing sensors 302, and flexible fiber weighing sensors 402. These sensors can accurately measure the weight of materials fed into each channel. The weighing data is transmitted to the intelligent control module in real time. Once the set threshold is reached, a confirmation button pops up on the touch screen controller 30, controlling the cementitious material hinged door 103, fine aggregate hinged door 203, steel fiber hinged door 303, and flexible fiber hinged door 403 to control the amount and timing of material feeding.

[0073] By intelligent regulation, the random dispersion of flexible fibers and the directional arrangement of steel fibers are synergistically controlled, thus producing high-strength and high-ductility composite materials.

[0074] The cementitious material conveying channel 105 has a built-in cementitious material mixing mechanism 104, which includes a cementitious material propeller. The mixing effect is monitored by a cementitious material speed sensor 106. The fine aggregate conveying channel 205 has a built-in fine aggregate mixing mechanism 204, which includes a fine aggregate propeller. The mixing effect is monitored by a fine aggregate speed sensor 206. The mixing tank 5 has a built-in mixing mechanism 501, which includes a mixing propeller. The mixing effect is monitored by a mixing speed sensor 502. The water or alkali activator required for mixing is controlled by a metering pump 6 to ensure stable mixing effect.

[0075] The cementitious material propeller, fine aggregate propeller, and mixture propeller adopt differentiated adaptation structures. The cementitious material propeller has a flow-guiding blade structure with an anti-stick coating sprayed on the blade surface, which is suitable for mixing and stirring cementitious materials and additives to prevent powder from clumping and adhering. The fine aggregate propeller has a rounded polished blade structure, which is suitable for fine aggregate stirring operations to avoid the problems of fine aggregate splashing and clumping. The mixture propeller has a rounded polished combined stirring blade structure, which is suitable for the final mixing of multiple materials to avoid fiber breakage and entanglement.

[0076] The device of this invention is an assembly-disassembly type, featuring a quick-release snap-fit ​​connection structure. It includes a cementitious material conveying channel 105, a fine aggregate conveying channel 205, and a steel fiber conveying channel 305 (equipped with a scraper screw; the screw blades have wear-resistant rounded corners; the scraper is made of a flexible material; and it is paired with a steel fiber rotating comb 304 and a double-layer steel fiber vibrating screen 306 to ensure the correct directional conveying of steel fibers of different diameters and to scrape away residual material from the inner wall of the channel in real time). The double-layer steel fiber vibrating screen 306 has a larger diameter screen hole on the upper layer and a smaller diameter screen hole on the lower layer. To achieve directional action, the flexible fiber conveying channel 405 (made of anti-static and wear-resistant material, with spiral guide patterns on the inner wall of the channel, combined with the low-frequency vibration of the vibrating screen to achieve non-entangled and uniform conveying of flexible fibers such as carbon fiber, PVA fiber, and natural fiber) can be installed and modified according to the characteristics of the input materials. The size and material of the conveying hopper, the diameter and material of the conveying channel, the type of propeller, and the size and material of the mixing container can all be adjusted and replaced according to the characteristics of the input materials to achieve the purpose of adapting to multiple materials and multiple working conditions.

[0077] The flexible fiber conveying channel 405 in the device can be adjusted according to the fiber type required for construction. The steel fiber rotating comb 304 and steel fiber double-layer vibrating screen 306 in the steel fiber conveying channel 305, and the flexible fiber vibrating screen 404 in the flexible fiber conveying channel 405, can all be disassembled and reassembled, and replaced in real time according to the type of input fiber.

[0078] By linking the weighing sensor, vibrating screen, rotating comb, and double-layer vibrating screen with the intelligent control module, the feeding sequence and frequency of flexible fibers are controlled in real time to achieve random and uniform distribution of flexible fibers in the mixture. At the same time, the conveying path and arrangement angle of steel fibers are controlled in a directional manner to achieve synergistic control of the random dispersion of flexible fibers and the directional arrangement of steel fibers, thus producing a composite material with both high mechanical strength and excellent ductility.

[0079] The metering pump 6 is an adjustable-speed quantitative metering pump that can receive the feeding weight data input from the intelligent control module and automatically match the water or alkali activator ratio of the cementitious material and fine aggregate (the water ratio is matched when the cementitious material is highly mixed with solid waste, and the alkali activator ratio is matched when it is entirely solid waste). The addition rate of water or alkali activator is adjusted in real time by an industrial-grade PLC1304 to accurately control the moisture content of the mixture and ensure that the mechanical properties of the mixture meet the requirements of the structural seismic reinforcement technology.

[0080] The nozzle 10 is a replaceable wear-resistant nozzle with an outer nozzle diameter adjuster. It works in conjunction with the real-time data feedback from the spray pressure sensor 16 and the ultrasonic sensor (15) (which detects the material passing through the cross section per unit time to provide feedback on the spraying effect). The spraying pressure and range are controlled within a certain range through the spraying power device 7, adapting to the spraying operation requirements of different reinforcement thicknesses and different construction locations.

[0081] The device is equipped with an intelligent automatic cleaning system. The cleaning process is started by double-clicking the power button. Preset parameters are used. First, clean water is injected quantitatively through the metering pump 6 (if an alkaline activator was used before, the corresponding cleaning solution can be injected accordingly). Each propeller reverses at a preset low speed to scrape off residual materials on the inner wall. Then, the jet power unit 7 drives the clean water to flush the entire pipeline through the jet pipe 8 and the jet nozzle 10. The cleaning time and clean water volume can be automatically matched according to the type of construction material. After cleaning, the water is automatically drained and the speed sensor monitors the speed of the propeller cavity to determine the cleaning standard status. The data is synchronously stored in the intelligent control module to realize unmanned operation of the entire cleaning process.

[0082] Specific Implementation Method Ten: Combining Figures 1 to 12 This embodiment describes a construction method based on an integrated intelligent device for material preparation and spraying reinforcement to improve the seismic toughness of structures, comprising the following steps:

[0083] Step 1: Based on the characteristics of the construction materials and the requirements for seismic reinforcement, complete the modular assembly and adaptation of the device;

[0084] Step 2: Move the device to the target construction area, complete the device positioning, debug the device to a near-horizontal and stable state, and confirm that the power supply to each electrical component is normal;

[0085] Step 3: Complete parameter preset through the control mechanism (12);

[0086] Step 4: Start material feeding and layered mixing;

[0087] Step 5: Start the spraying operation;

[0088] Step Six: Construction Finishing and Intelligent Cleaning.

[0089] In step one, the cementitious material conveying hopper 101, fine aggregate conveying hopper 201, steel fiber conveying hopper 301, and flexible fiber conveying hopper 401 are assembled, and corresponding cementitious material weighing sensors 102, 202, 302, and 402 are matched with cementitious material hinged doors 103, 203, 303, and 403. The cementitious material mixing mechanism 104, 204, and 501 are replaced with suitable ones. A screw with a scraper, a steel fiber rotating comb 304, and a steel fiber double-layer vibrating screen 306 are added to the steel fiber conveying channel 305. A flexible fiber vibrating screen 404 is added to the flexible fiber conveying channel 405. Simultaneously, it is confirmed that the specifications of the mixing tank 5, spray pipe 8, and spray nozzle 10 are compatible with the construction requirements. Finally, a metering pump 6 is installed on the mixing tank 5.

[0090] In step two, the device is moved to the target construction area, and the device is positioned by the traveling mechanism 13. The horizontal sensor 1304 monitors the data in real time and the device is adjusted to a near-horizontal and stable state. When there is an external power supply, the motor 1102 is used to supply power, and when there is no external power supply, the lithium battery 1101 is switched to supply power. It is confirmed that the power supply of each electrical component such as the mixing mechanism, sensor, nozzle, and track is normal.

[0091] In step three, parameter presets are completed via the touchscreen controller 1201. The rotation speeds of the touchscreen controller 1201, fine aggregate mixing mechanism 204, and mixture mixing mechanism 501 are retrieved from or customized from the built-in database of construction parameters for various types of reinforcement materials. The target temperature of the circulating water temperature control device 17 is also preset. Simultaneously, the parameters for adding water or alkali activator to the metering pump 6 (matched according to the type of cementitious material), the pressure of the nozzle 10, and the spray angle parameters of the two angle adjusters 14 are preset. The weight thresholds and feeding sequence of the cementitious material, fine aggregate, steel fiber, and flexible fiber are input. The monitoring reference values ​​of the temperature sensor 18, cementitious material rotation speed sensor 106, fine aggregate rotation speed sensor 206, mixture rotation speed sensor 502, ultrasonic sensor 15, and spray pressure sensor 16 are set. The data transmission between each sensor is confirmed to be smooth via the information receiving and transmission antenna 1203, completing the linkage debugging between the industrial-grade PLC 1202 and the intelligent control system of the electronic component installation area 1204.

[0092] In step four, when initiating material feeding and stratified mixing, the cementitious material and admixture are fed into the cementitious material conveying hopper 101, and dispersed by the cementitious material mixing mechanism 104. The cementitious material speed sensor 106 monitors the mixing status in real time. Fine aggregate is fed into the fine aggregate conveying hopper 201, and stirred by the fine aggregate mixing mechanism 204 to prevent clumping. The fine aggregate speed sensor 206 monitors the mixing status in real time. The metering pump 6 automatically matches the water or alkali activator ratio according to the feeding weight of the cementitious material and fine aggregate (the water ratio is matched when the cementitious material is highly mixed with solid waste, and the alkali activator ratio is matched when it is entirely solid waste), and the water addition rate is adjusted in real time by the industrial-grade PLC 1202. The circulating water temperature control device 17, in conjunction with the temperature sensor 18, controls the temperature of the mixture within a preset range. Flexible fibers are weighed in the flexible fiber conveying hopper 401, dispersed by the flexible fiber vibrating screen 404, and then conveyed by the flexible fiber conveying channel 405. Steel fibers are weighed in the steel fiber conveying hopper 301, combed by the steel fiber rotating comb 304, vibrated and screened by the steel fiber double-layer vibrating screen 306, and then conveyed by the steel fiber conveying channel 305. After all materials enter the mixing tank 5, the mixing mechanism 501 completes the final mixing, and the mixing speed sensor 502 monitors the mixing effect in real time.

[0093] In step five, when the spraying operation is started, the properly mixed reinforcement material is pushed to the spraying pipeline 8 by the spraying power unit 7. The spraying direction is coarsely adjusted by the angle adjuster 14 in the middle and finely adjusted by the angle adjuster 14 at the front. The spray nozzle 10 controls the spraying pressure and area through the real-time data feedback from the spraying pressure sensor 16 and the spraying nozzle diameter adjuster installed on the outer layer. During the spraying process, the ultrasonic sensor 15 monitors the uniformity of spraying, the spraying pressure sensor 16 provides real-time feedback of pressure data, and the intelligent control module adjusts the stable output of the spraying power unit 7 to ensure stable spraying effect.

[0094] In step six, during the final stage of construction and intelligent cleaning, the mixing and spraying systems are turned off, and the power button on the touchscreen controller 1201 is double-clicked to start the intelligent automatic cleaning system, with preset cleaning parameters. The metering pump 6 injects a quantitative amount of clean water, and each propeller reverses at a preset low speed to scrape off residual materials from the inner wall. Then, the spraying power unit 7 drives the clean water through the spraying pipe 8 and spray nozzle 10 to flush the entire pipeline. The cleaning time and clean water consumption are automatically matched according to the type of construction material. After cleaning, the water is automatically drained. The speed sensor monitors the speed of the propeller cavity to determine the cleaning standard status, and the data is synchronously stored in the intelligent control module. The monitoring data throughout the process is exported to analyze the construction effect and optimize subsequent construction parameters.
