Description

Technical Field

[0001] The present invention relates to the technical field of highway construction, and in particular to a digital paving system for prefabricated arched skeletons on highway slopes and a method for using the system. Background Art

[0002] Arched skeleton protection for highway slopes is a crucial measure for ensuring roadbed stability. Traditional construction methods rely primarily on manual or semi-mechanized operations, resulting in technical bottlenecks and industry pain points such as poor process coordination, low construction efficiency, insufficient precision, and difficulty in controlling construction quality. While existing technologies have improved some aspects of this process (such as precast block production and transportation), they have yet to form a fully digital closed-loop system, leading to core issues such as process fragmentation and loss of precision control.

[0003] At this stage, there is an urgent need to develop a highway slope prefabricated arch skeleton paving system that integrates digital design, intelligent construction equipment, and real-time quality feedback to break through the bottleneck of efficiency and quality safety compatibility and promote the industry's transformation to intelligent and digital. Currently, most paving methods are manual or semi-mechanized. Manual paving is labor-intensive and inefficient, and it is difficult to ensure paving accuracy. It is easy to cause uneven splicing of the arch skeleton, affecting the slope protection effect and aesthetics. Although semi-mechanized paving has improved efficiency to a certain extent, it still relies on manual operation and lacks precise positioning and control methods. It cannot meet the high quality and high efficiency requirements of modern highway construction. In addition, traditional paving methods make it difficult to monitor and control the construction process in real time, and it is impossible to detect and correct deviations in construction in a timely manner, which easily leads to increased maintenance costs in the later stages.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] The digital paving system for prefabricated arch frames on highway slopes provided by the embodiment of the present invention mainly realizes accurate and efficient paving of prefabricated arch frames on slopes through digital technology. The spatial layout of the digital paving system for prefabricated arch frames is studied according to the engineering characteristics of the project, including an automatic mortar mixing system, a temporary classification and storage system for prefabricated arch frame pieces, a prefabricated arch frame installation system and a corresponding intelligent control system. Figure 1-2 As shown, the details are as follows:

[0038] The automatic mortar mixing system consists of a raw material storage system, a metering and batching system, a mixing system, a control unit, and a conveying system. The raw material storage system includes a cement silo, a sand silo, and associated water tank storage silos. The metering and batching system features dedicated metering hoppers for different materials, ensuring precise feeding. The conveying system utilizes a frequency-controlled screw conveyor, and the mixing system uses a twin-shaft forced mixer to further ensure uniform mortar mixing and improve mortar production quality. The control unit utilizes a PLC controller with a 10-inch color touchscreen, which intuitively displays system operating status and parameters. It features fast processing speed and high reliability, and supports independently developed control software, supporting functions such as recipe management, production monitoring, and data logging. The entire automatic mortar mixing system simply requires inputting the mix ratio into the control unit, and the system accurately produces the required volume. Through precise batching control and thorough mixing, the system ensures consistent mortar quality throughout each batch. The increased level of automation reduces the number of operators and lowers labor costs.

[0039] The temporary classification and storage system for prefabricated arched skeleton pieces in this embodiment is made of Q345B high-strength steel to ensure structural stability, and two standard storage units are provided for storing prefabricated arched skeleton pieces of different specifications and models respectively. The standard storage unit dimensions are: length × width × height = 3.5m × 1m × 1.2m; wherein, the prefabricated arched skeleton pieces are horizontally arranged in the two standard storage units, and the two standard storage units adopt the form of multi-layer three-dimensional storage racks with a storage height not exceeding 1.2m. Buffer rubber pads are provided between the layers to prevent damage to the surface of the skeleton pieces, and rubber anti-collision strips are provided around the storage racks. By adopting the multi-layer three-dimensional storage method, the storage capacity per unit area is increased by 3-5 times compared with traditional stacking, which can greatly improve storage efficiency. In addition, the modular design can be flexibly adjusted according to the site to adapt to different construction site conditions.

[0040] In addition, the storage rack and the automatic mortar mixing system are set on the same mobile trolley, which moves synchronously with the installation trolley when in use, and the arch skeleton pieces are retrieved and installed through the mechanical arm of the installation trolley, such as Figure 3 shown.

[0041] In the above embodiment, the core module of the prefabricated arch frame installation system is the prefabricated block automatic installation formwork, which can integrate the functions of automatic formwork assembly and slope paving, and realize the precise control of the arch frame line shape and joints. It mainly includes the following parts:

[0042] Automatic installation formwork for precast blocks: It is fixed on a trolley steel frame, with an arched steel frame on top that matches the shape of the arched slope protection. An automatically retractable skeleton piece support is mounted on the steel frame. The support is L-shaped, and the skeleton piece is moved vertically by the automatic retraction of the hook arm to complete the paving work. The support is set around the steel frame, and each precast block has supports on both sides to ensure its stability during vertical movement.

[0043] Automatic grabbing robot arm: fixed on the trolley steel frame, the top of the robot arm is equipped with a displacement sensing device and a vacuum suction cup. Through the intelligent control system and the instructions issued by the corresponding drive system, it performs adaptive bending and rotation to grab and unload the prefabricated blocks; the grabbed prefabricated blocks are unloaded onto the "L"-shaped support of the corresponding installation formwork, and are assembled and adjusted on the installation formwork. After assembly is completed, the hook arm automatically moves downward to the slope surface where mortar has been placed, thereby completing the paving work;

[0044] Mortar funnel moving track: Made of Q345B high-strength steel, it is equipped with precision gears that align with the mortar funnel drive gears to achieve fine movement of the mortar funnel. Various sensing devices and corresponding power supply lines are laid on it to achieve high-precision position adjustment of the mortar funnel based on preset parameters or real-time feedback data.

[0045] Mortar funnel: Made of 1mm thick steel plate, the top is connected to the track via a hook drive, which moves on the track. The hook drive is equipped with displacement and weight sensors to control the precise movement and discharge of the mortar funnel. The top of the funnel is connected to the mortar box via a mortar pump pipe. The produced mortar is transported to the mortar funnel through the pump pipe, and then the mortar is evenly laid on the slope through the funnel. In addition, after the prefabricated blocks are laid, the mortar funnel is used to accurately fill the seams, further improving the construction quality of the arch skeleton slope protection. Please refer to Figure 4-5 .

[0046] The intelligent control system in the embodiment of the present invention is composed of computers, software, sensors, controllers and required power lines. It uses information technology to collect, process, store and analyze data during the construction of prefabricated arch skeletons, and then makes corresponding responses, issuing corresponding work instructions to control various digital equipment to perform construction operations, thereby realizing intelligent and digital construction.

[0047] Specifically, data is collected through sensors installed on various devices, collecting key parameters such as weight, displacement, and dimensions in real time. Using network technology, the collected data is transmitted to a computer, where a database is established to securely store all construction process data. Big data analysis techniques are used to process the stored data, promptly detecting anomalies and issuing warnings to ensure construction quality and safety. Operators use the control system to make corresponding adjustments to construction content based on the data provided by the data management system. Intelligent control systems help improve construction quality, reduce production costs, shorten construction schedules, and enhance the intelligence and digitalization of the entire production process.

[0048] Based on the above paving system, an embodiment of the present invention further provides a method for using the highway slope prefabricated arch skeleton digital paving system, as follows:

[0049] S1: Install the trolley used by the automatic mortar mixing system and the temporary classification and storage system for prefabricated arch frame pieces on the completed roadbed, and then install the prefabricated arch frame installation system trolley on the slope at the corresponding location;

[0050] S2: Install the intelligent control system, electric drive system, water tank, cement silo, sand silo, twin-shaft forced mixer, mortar storage box, two standard storage units, and corresponding hardware and software as well as power lines on the trolley on the top of the roadbed;

[0051] S3: Install an electric drive system, intelligent control system, precast block automatic installation formwork, automatic grabbing robot arm, mortar funnel moving track, movable mortar funnel, various sensors, controllers on the trolley on the slope, and configure the relevant circuit network;

[0054] S6: After receiving the mortar paving instruction from the intelligent control system, the mortar funnel places mortar on the slope according to the designed trajectory;

[0055] S7: After receiving the assembly instruction from the intelligent control system, the automatic grasping robot arm grasps the prefabricated block through the vacuum suction cup at the end of the robot arm, unloads the grasped prefabricated block onto the "L"-shaped support of the corresponding installation mold frame, and performs assembly and adjustment on the installation mold frame;

[0056] S8: After assembly is complete, the arm automatically retracts and extends to move downward onto the pre-paved slope, completing the paving process. Specifically, RTK-GNSS positioning technology and 3D laser scanning modeling can be used to achieve a prefabricated component installation position error of ≤1cm and an angular deviation of ≤0.5°. Compared to traditional manual layout, this significantly improves the accuracy of skeleton splicing. The paving system can be equipped with an inclination sensor and an automatic leveling system to ensure that the horizontal error of a single component is ≤2mm, and paving parameters can be adjusted dynamically in real time to adapt to slope terrain changes within ±3°.

[0057] In the above embodiment, the present invention controls the precise delivery of various raw materials through the input mix ratio and mortar demand, controls the mixing time of the forced mixing equipment, and thus realizes the precise production of mortar, while monitoring the key parameters in the production process to ensure product quality; secondly, it can use computer software to design the slope linear values ​​provided on the construction drawing, and then accurately extract various work processes and corresponding construction parameters in combination with the actual slope and flatness of the on-site slope, generate work instructions through programming, and then control the corresponding equipment to perform production work, thereby realizing the precise paving of prefabricated arch skeleton pieces, while monitoring the key parameters in the production process to ensure product quality.

[0058] In order to further better explain that the present invention can realize the digital, efficient and precise installation of arch skeleton slope protection of highways and achieve the purpose of reducing costs and increasing efficiency, it is combined with the design technical standards and national industry specifications of the arch skeleton slope protection in the Jinan to Weishan Expressway Jinan to Jining New Airport section of Shandong Province. Construction is carried out, and 4-6 arch skeletons can be installed per hour, which is more than 300% higher than the traditional labor efficiency. It has 24-hour continuous operation capability and shortens the single-kilometer slope protection construction period by more than 50%. Secondly, the quality stability is enhanced. Its digital construction process parameters are solidified, eliminating the differences in manual operation. The component splicing seam width error is controlled within ±1mm, and the installation time, position and process parameters of each component are automatically recorded to form a complete quality traceability file. Moreover, the cost-effectiveness is optimized. The number of construction personnel per kilometer is reduced from 20-30 in the traditional mode to 5-8, saving more than 60% of labor costs. The operating skills threshold is lowered, and ordinary workers can take up their posts after 3 days of training. Precise component positioning reduces the need for cutting and trimming, reducing material loss from 8% to below 3%. The intelligent batching system optimizes mortar mix ratios, saving 15% in cementitious materials. Furthermore, in terms of safety risk management, paving equipment handles over 95% of installation tasks, reducing manual climbing work by 80% and preventing personnel from being exposed to dangerous slope areas.

[0059] In summary: The digital paving system and method for using the prefabricated arch skeleton of the highway slope provided by the present invention realizes the whole process management from data collection, construction to quality monitoring through digital technology, facilitates the monitoring and management of the construction process, and improves the scientificity and standardization of construction management.
