Description
Technical Field
[0001] This invention relates to the field of roadbed engineering construction technology, specifically to an intelligent construction system and method for the entire process of cast-in-place side ditch construction on highways. Background Technology
[0002] In the construction of cast-in-place side ditches for highways, traditional methods follow a linear sequence of "surveying and setting out—ditch excavation—foundation treatment—formwork erection—concrete pouring—curing and formwork removal." Each step is carried out independently, and coordination between them relies heavily on manual labor. Regarding construction tools, traditional methods primarily use small hand tools and simple machinery. These tools have low technological content, are physically demanding on workers, and have low efficiency. Overall, traditional cast-in-place side ditch construction methods suffer from low automation, high labor intensity, long construction cycles, and significant challenges in quality and cost control, making it difficult to meet the demands of modern highway construction for efficient and high-quality work. Summary of the Invention
[0003] The purpose of this invention is to provide an intelligent construction system and method for the entire process of cast-in-place side ditch construction on highways. This system can not only improve the efficiency and quality of cast-in-place side ditch construction, reduce labor costs, and shorten the project cycle, but also play an important role in promoting the modernization and intelligence of road engineering construction, thereby addressing the shortcomings of existing technologies.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] An intelligent construction system for the entire process of cast-in-place side ditch construction on highways includes an equipment frame and mobile unit, an RTK positioning unit, a trenching unit, a slipform concrete pouring unit, a temporary concrete storage unit, and an intelligent control unit. The equipment frame and mobile unit serve as the foundation for the overall construction equipment's support and movement. The RTK positioning unit includes at least three high-precision RTK measuring devices, each connected to the intelligent control unit for positioning and measurement tasks. The trenching unit is a trenching tool integrating trenching, soil unloading, measurement components, and automation functions, used to automatically complete the entire trenching process. The slipform concrete pouring unit consists of mold components, material collection and pouring components, and a vibration... The system comprises a tamping assembly and an intelligent control module, used to automate the pouring of concrete for the side ditch. The temporary concrete storage unit consists of a concrete silo and a mixing device, with the mixing device built into the silo. The silo has a level sensor at the top and a discharge port and hydraulic unloading gate at the bottom. The intelligent control unit regulates the opening and closing of the hydraulic unloading gate, the operation of the mixing device, the level sensor, and material replenishment, achieving precise coordination with the slipform concrete pouring unit. The intelligent control unit consists of a computer, sensors, data storage and analysis software, and power lines. It is located on the top of the equipment frame and the mobile unit, used to collect various data during the construction process in real time, analyze and process the data, and issue commands to control the coordinated operation of each equipment unit.
[0006] Furthermore, the equipment frame and moving unit consist of a support mechanism, a height adjustment mechanism, a moving mechanism, and a hoisting trolley mechanism. The support mechanism is constructed by welding or bolting together the top steel section of the triangular truss, the bottom steel section of the triangular truss, the end steel section of the triangular truss, the connecting round steel pipe of the triangular truss, and the bottom connecting steel section of the triangular truss. The height adjustment mechanism is a double-bar hydraulic triangular truss support lifting member set at both ends of the truss. The bottom of the triangular truss support lifting member is provided with a transverse connecting rod for adjusting the height and providing stable support between the triangular truss and the ground foundation. The moving mechanism is a CNC double-flanged traveling wheel, which is set at the bottom of the transverse connecting rod for driving the entire frame to move laterally on the steel track laid on the original ground. The hoisting trolley mechanism consists of a hoisting trolley, a working lifting member, a turntable, and a transition connecting device.
[0007] Furthermore, the centers of the hoisting trolley, working lifting rod, turntable, and transition connection device are all on the same vertical line after installation. The hoisting trolley is assembled onto the bottom steel of the triangular truss by a snap-fit method, and sliding wheels are provided on the contact surface with the bottom steel of the triangular truss. The hoisting trolley can move flexibly along the length of the bottom steel of the triangular truss through the cooperation of the sliding wheels and the bottom steel of the triangular truss. The working lifting rod is connected to the hoisting trolley and is used to control the lifting of the entire hoisting trolley mechanism. The turntable body is disc-shaped and connected to the lower end of the working lifting rod, which is used to realize continuous rotation and fixed-point angle adjustment. The transition connection device is an integral stepped flange structure. The upper and lower ends of the transition connection device are respectively provided with precision-machined connection surfaces. The upper connection surface is fixed to the lower part of the turntable, and the lower connection surface is connected to various corresponding equipment as needed.
[0008] Furthermore, the various types of equipment include front auxiliary legs, grooving units, slipform concrete pouring units, temporary concrete storage units, and rear auxiliary legs.
[0009] Furthermore, one high-precision RTK measuring device in the RTK positioning unit is used to measure the planar position and elevation data of the embankment / cut slope toe in the field; the other two high-precision RTK measuring devices are respectively installed on the top of the trenching unit and the slipform concrete pouring unit.
[0010] Furthermore, the grooving tool is a rigid mold customized according to the cross-sectional shape of the cast-in-place drainage ditch. The position of the grooving tool is calculated by the high-precision RTK measuring equipment on the top and the actual measured plane position and elevation data of the embankment slope toe by the on-site operators, and is automatically adjusted and positioned by the intelligent control unit to carry out the excavation operation.
[0011] Furthermore, the positioning calculation method for the slotted unit is as follows:
[0012] Definitions: A: Measured offset of embankment toe; H: Measured elevation of embankment toe.
[0013] A1: Measured offset of the center of the grooving tool; H1: Elevation of the top surface of the overhead crane to which the grooving tool is connected.
[0014] A adjustment = A1 - A - Design slope protection width - Design side ditch top width / 2;
[0015] H adjustment = H1 - H - height of the crane system - elongation of the crane working lifting rod.
[0016] Furthermore, the mold assembly consists of a bottom mold, side molds, and stiffening ribs. The material collection and pouring assembly includes a hopper located above the front end of the mold assembly for receiving concrete from the temporary concrete storage unit. A liquid level sensor is installed at the bottom 1 / 5 of the hopper, and the liquid level sensor is connected to the intelligent control module. The vibration assembly is an attached vibrator installed at the bottom and sides of the mold assembly. The attached vibrator is equipped with a vibration time control device, which can automatically adjust the vibration time according to the concrete pouring speed. The intelligent control module establishes a data communication connection with the intelligent control unit. The intelligent control module acquires the operating data of the side ditch grooving unit, the mold assembly, and the RTK positioning unit in real time through the data acquisition module to realize dynamic control of the pouring process.

[0022] S5: After the concrete mixer truck injects concrete into the temporary concrete storage unit, the intelligent control unit collects real-time data from the material level sensor to accurately determine the material status in the concrete silo, and then automatically controls the temporary concrete storage unit to move and open and close the hydraulic unloading gate to complete the material replenishment operation for the slipform concrete pouring unit.
[0023] S6: The slipform concrete pouring unit starts pouring and vibration operations, and the construction is repeated until the side ditch of this section is completed. Then, the entire crane is moved forward to the front of the equipment frame, and the front auxiliary legs and rear auxiliary legs are lowered and supported on the ground.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0036] Please see Figure 1-5 This invention provides an intelligent construction system for the entire process of cast-in-place side ditch construction on highways, mainly used to improve the efficiency and quality of cast-in-place side ditch construction, reduce labor intensity and labor costs, and shorten the project cycle. It includes an equipment frame and moving unit, an RTK positioning unit, a grooving unit 15, a slipform concrete pouring unit 16, a temporary concrete storage unit 17, and an intelligent control unit 19.
[0037] The equipment frame and mobile unit serve as the foundation for the overall construction equipment's load-bearing and movement; it consists of a support mechanism, a height adjustment mechanism, a moving mechanism, and a crane mechanism; for example... Figure 1-3As shown: The support mechanism is constructed by welding or bolting together the top steel section 1, bottom steel section 2, end steel section 3, connecting round steel pipe 4, and bottom connecting steel section 5 of the triangular truss. The height adjustment mechanism is a double-rod hydraulic triangular truss support lifting rod 10 set at both ends of the truss. The bottom of the triangular truss support lifting rod 10 is provided with a transverse connecting rod 11, which is used to realize the height adjustment and stable support between the triangular truss and the ground foundation. It plays a crucial role in the overall operational safety and adaptability. The bottom of the hydraulic rod uses ordinary steel as the foundation, and the double-rod hydraulic rods are also connected laterally to form a whole, which enhances the structural stability and anti-lateral displacement ability. The moving mechanism is a CNC double-flange traveling wheel 12, which is set at the bottom of the transverse connecting rod 11. It is used to drive the entire frame to move laterally on the steel track 13 laid on the original ground. The double flange spacing of the CNC double-flange traveling wheel 12 is adapted to the model of the steel track 13.
[0038] In the above embodiment, the crane mechanism is composed of a crane 6, a working lifting rod 7, a turntable 8, and a transition connection device 9; the centers of the crane 6, the working lifting rod 7, the turntable 8, and the transition connection device 9 after installation are on the same vertical line. Specifically, the overhead crane 6 is assembled onto the bottom steel section 2 of the triangular truss using a snap-fit method, and sliding wheels are provided on the contact surface with the bottom steel section 2 of the triangular truss. The cooperation between the sliding wheels and the bottom steel section 2 of the triangular truss allows the overhead crane 6 to move flexibly along the length of the bottom steel section 2 of the triangular truss. The working lifting rod 7 is connected to the overhead crane 6 and is used to control the lifting of the entire overhead crane mechanism. The turntable 8, in a disc shape, is connected to the lower end of the working lifting rod 7, enabling 360-degree continuous rotation and fixed-point angle adjustment, and can also be adjusted vertically. The transition connection device 9 has a stepped flange structure, with precision-machined connection surfaces at both ends. The upper connection surface is fixed to the lower part of the turntable 8, and the lower connection surface connects to various types of equipment as needed. These equipment include the front auxiliary support leg 14, the slotting unit 15, the slipform concrete pouring unit 16, the temporary concrete storage unit 17, and the rear auxiliary support leg 18, such as... Figure 2 As shown.
[0039] The RTK positioning unit in this embodiment of the invention is used to complete the positioning measurement task. It includes no less than three high-precision RTK measuring devices 20. One high-precision RTK measuring device 20 is used to measure the plane position and elevation data of the embankment / cut slope toe in the field. The other two high-precision RTK measuring devices 20 are respectively installed on the top of the trenching unit 15 and the slipform concrete pouring unit 16, and must be accurately aligned with the center position of the trenching unit 15 and the mold assembly. The high-precision RTK measuring devices 20 establish a data communication connection with the intelligent control unit 19. By collecting and processing the RTK measurement data in real time, the device translation and hydraulic rod lifting actions are automatically adjusted to achieve precise control of the construction process.
[0040] like Figure 4 As shown, the trenching unit 15 in this embodiment of the invention is a trenching tool that integrates trenching, soil unloading, measurement components, and automation functions, used to automatically complete the entire trenching operation. The trenching tool is a rigid mold customized according to the cross-sectional shape of the cast-in-place drainage ditch. The position of the trenching tool is calculated by the high-precision RTK measuring device 20 on top and the actual measured embankment slope toe plane position and elevation data by on-site operators, and is automatically adjusted and positioned by the intelligent control unit 19 to carry out the excavation operation. The specific positioning calculation method is as follows:
[0041] Definitions: A: Measured offset of embankment toe; H: Measured elevation of embankment toe.
[0042] A1: Measured offset of the center of the grooving tool; H1: Elevation of the top surface of the overhead crane to which the grooving tool is connected.
[0043] A adjustment = A1 - A - Design slope protection width - Design side ditch top width / 2;
[0044] H adjustment = H1 - H - height of the crane system - elongation of the crane working lifting rod.
[0045] like Figure 5As shown, the slipform concrete pouring unit 16 in this embodiment of the invention consists of a mold assembly, a material collection and pouring assembly, a vibration assembly, and an intelligent control module, used to realize the automated pouring of side ditch concrete; wherein, the mold assembly consists of a bottom mold 22, a side mold 21, and stiffening ribs, and is made of high-strength alloy steel plate, which is suitable for various side ditch cross sections such as trapezoidal and rectangular. The inner side is mirror polished to reduce concrete adhesion. The center of the mold assembly is vertically aligned with the crane system. The installation position of the template is precisely controlled by calculating the plane position and elevation data of the embankment slope toe measured on site through the RTK at the top (the calculation method is the same as the grooving unit calculation). The material collection and pouring assembly includes a hopper 24 located above the front end of the mold assembly, used to receive concrete delivered by the temporary concrete storage unit 17. A liquid level sensor 25 is installed at the bottom 1 / 5 of the hopper 24, and the liquid level sensor 25 is connected to the intelligent control module. When the material level is lower than the sensor height, the intelligent control module automatically triggers a replenishment command to ensure continuous pouring. The paver advances at a set speed, the mold assembly slides relative to the ground, and the freshly vibrated concrete is squeezed and shaped under the constraint of the mold, enhancing its initial strength with the help of lateral pressure. The vibration assembly consists of attached vibrators 23 installed at the bottom and sides of the mold assembly. The attached vibrators 23 are equipped with a vibration time control device, which can automatically adjust the vibration time according to the concrete pouring speed to prevent over-vibration or under-vibration. The intelligent control module establishes a data communication connection with the intelligent control unit 19. The intelligent control module acquires real-time operating data of the side ditch trenching unit 15, the mold assembly, and the RTK positioning unit through the data acquisition module, including equipment status, construction parameters, precise location information, environmental information, etc., to achieve dynamic control of the pouring process.
[0046] like Figure 6 As shown, the temporary concrete storage unit 17 in this embodiment of the invention consists of a concrete silo 27 and a mixing device 28. The concrete silo 27 adopts a closed structure design and has a specific capacity, which can temporarily store a certain amount of concrete to ensure the continuity of the pouring operation. The mixing device 28 is built into the concrete silo 27 and can continuously mix the stored concrete to effectively prevent segregation. The concrete silo 27 is equipped with a material level sensor 31 at the top and a discharge port 29 and a hydraulic unloading gate 30 at the bottom. The opening and closing of the hydraulic unloading gate 30, the operation of the mixing device 28, the material level sensor 31, and the material replenishment are controlled by the intelligent control unit 19 to achieve precise coordination with the slipform concrete pouring unit 16.
[0047] Furthermore, the intelligent control unit 19 of this invention is an integrated information system, centrally located at the top of the triangular truss, and mainly consists of a computer, sensors, data storage and analysis software, and power grid lines. It collects various data (positioning, equipment status, liquid level sensors, material information, etc.) in real time during the construction process, analyzes and processes the data, issues commands to control the coordinated operation of various devices, and achieves intelligent and digital management of the entire construction process, reducing manual intervention.
[0048] To further explain the implementation process of the above construction system, this invention also provides an intelligent construction method for the entire process of cast-in-place side ditch construction on highways, including the following steps:
[0049] S1: Manually lay steel rails 13 perpendicular to the route in the section to be constructed, assemble each unit component and test run, and input construction parameters such as slope protection width, side ditch top width and side ditch depth into the intelligent control unit 19.
[0050] S2: Surveyors use the matching high-precision RTK surveying equipment to measure the plane coordinates and elevation of the slope toe line of the section to be constructed, which serves as the construction positioning benchmark.
[0051] S3: Intelligent control unit 19 processes the RTK data at the top of the grooving unit 15 and the actual measured data at the foot of the slope, calculates the adjustment value, controls the equipment frame and moving unit to move laterally to the design center of the ditch, adjusts the height of the working lifting rod 7 and the longitudinal position of the hoisting crane 6, starts the grooving operation, and adjusts the fine angle of the ditch line shape through the turntable 8. The excavated soil is uniformly piled at the front end.
[0052] S4: The intelligent control unit 19 processes the measured data of the top RTK of the slipform concrete pouring unit 16, the RTK of the grooving unit 15, and the slope toe, calculates the positioning parameters, controls the crane 6 to transport the slipform concrete pouring unit 16 to the starting point of the trench, adjusts the working lifting rod 7 to the design elevation of the side ditch, and waits for pouring.
[0053] S5: After the concrete mixer truck injects concrete into the temporary concrete storage unit 17, the intelligent control unit 19 collects real-time data from the material level sensor 31 to accurately determine the material status in the concrete silo 27, and then automatically controls the temporary concrete storage unit 17 to move and open / close the hydraulic unloading door 30 to complete the material replenishment operation for the slipform concrete pouring unit 16.
[0054] S6: The slipform concrete pouring unit 16 starts pouring and vibration operations, and the construction is repeated until the side ditch of this section is completed. Then, the crane 6 moves forward as a whole to the front of the equipment frame, and the front auxiliary legs 14 and the rear auxiliary legs 18 are lowered and supported on the ground. Then, the triangular truss support lifting rods 10 and steel rails 13 are retracted, and the track is re-laid to enter the next section of work.
[0055] In summary, the present invention provides an intelligent construction system and method for the entire process of cast-in-place side ditch construction on highways. By integrating digital design and automated control technologies, it breaks away from the reliance on manual labor in traditional construction, achieving high efficiency, precision, and controllability throughout the entire process from trenching to pouring. It is particularly suitable for large-scale, high-standard side ditch construction on highways, significantly improving construction efficiency, reducing quality defect rates, and decreasing labor costs and safety risks. It is applicable to large-scale highway construction projects and has significant engineering application value.

The intelligent construction system for the entire process of cast-in-place side ditch construction on highways as described in claim 1, characterized in that: The mold assembly consists of a bottom mold (22), a side mold (21), and stiffening ribs. The material collection and pouring assembly includes a hopper (24) located above the front end of the mold assembly, which is used to receive concrete delivered by the temporary concrete storage unit (17). A liquid level sensor (25) is installed at the bottom 1 / 5 of the hopper (24), and the liquid level sensor (25) is connected to the intelligent control module. The vibration assembly is an attached vibrator (23) installed at the bottom and side of the mold assembly. The attached vibrator (23) is equipped with a vibration time control device, which can automatically adjust the vibration time according to the concrete pouring speed. The intelligent control module establishes a data communication connection with the intelligent control unit (19). The intelligent control module obtains the operating data of the side ditch grooving unit (15), the mold assembly, and the RTK positioning unit in real time through the data acquisition module, so as to realize the dynamic control of the pouring process.
9. A fully intelligent construction method for cast-in-place side ditches on highways, implemented based on the fully intelligent construction system for cast-in-place side ditches on highways as described in claim 1, characterized in that... Includes the following steps: S1: Manually lay steel rails (13) perpendicular to the route in the section to be constructed, assemble each unit component and test run, and input the construction parameters of slope protection width, side ditch top width and side ditch depth in the intelligent control unit (19); S2: Surveyors use the matching high-precision RTK surveying equipment (20) to measure the plane coordinates and elevation of the slope toe line of the section to be constructed, as the construction positioning benchmark; S3: The intelligent control unit (19) processes the top RTK data and slope foot measured data of the trenching unit (15), calculates the adjustment value, controls the equipment frame and moving unit to move laterally to the design center of the ditch, adjusts the height of the working lifting rod (7) and the longitudinal position of the crane (6), starts the trenching operation, adjusts the fine angle of the ditch line through the turntable (8), and the excavated soil is uniformly piled at the front end; S4: Intelligent control unit (19) processes the RTK of the top of the slipform concrete pouring unit (16), the RTK of the grooving unit (15) and the actual measured data of the slope foot, calculates the positioning parameters, controls the crane (6) to transport the slipform concrete pouring unit (16) to the starting point of the trench, adjusts the working lifting rod (7) to the design elevation of the side ditch, and waits for pouring; S5: After the concrete mixer truck injects concrete into the temporary concrete storage unit (17), the intelligent control unit (19) collects real-time data from the material level sensor (31) to accurately determine the material status in the concrete silo (27), and then automatically controls the temporary concrete storage unit (17) to move and open / close the hydraulic unloading gate (30) to complete the material replenishment operation for the slipform concrete pouring unit (16). S6: The slipform concrete pouring unit (16) starts pouring and vibration operation, and the construction is carried out in cycles until the ditch of this section is completed. Then, the crane (6) moves forward as a whole to the front of the equipment frame, and the front auxiliary legs (14) and rear auxiliary legs (18) are lowered and supported on the ground. Then, the triangular truss support lifting rods (10) and steel rails (13) are retracted, and the next section of operation is started.
