Description

Technical Field

[0001] The present invention belongs to the technical field of roadbed drainage construction, and more specifically, relates to a novel municipal road roadbed drainage system construction device and construction method. Background Art

[0002] Roadbed drainage ditches are a vital drainage facility in roadbed engineering. Their main function is to collect and drain the water on the road surface and inside the roadbed to ensure the stability of the road structure and driving safety. These drainage facilities prevent water from penetrating into the roadbed material through an effective drainage system, reduce roadbed diseases such as settlement and landslides, and avoid road damage and traffic safety hazards caused by water accumulation.

[0003] Due to the open-air nature of traditional roadbed drainage ditches, debris such as mud, leaves, and garbage carried by rainwater are easily accumulated in the drainage ditches, causing blockages and affecting drainage efficiency. In severe cases, it will cause waterlogging and flooding. In addition, the roadbed drainage ditch is constructed using the traditional formwork casting method, which has the following disadvantages: the traditional formwork casting requires the installation of the formwork first, and then the pouring of concrete. After the concrete reaches a certain strength, the formwork is removed and then transferred to the next location to repeat the above process. This process is time-consuming and has a low construction efficiency. The traditional formwork method requires frequent disassembly and assembly of the formwork, which not only increases manpower requirements but also increases labor intensity. Although the initial investment in traditional formwork may be low, its low construction efficiency leads to an increase in overall labor costs, equipment rental costs, and time costs. The traditional formwork method is prone to errors during the splicing and disassembly of the formwork, which affects the dimensional accuracy and surface finish of the concrete components. The formwork needs to be positioned, reinforced, and adjusted multiple times, and on-site management is cumbersome.

[0004] Therefore, at this stage, there is an urgent need for a new type of municipal road subgrade drainage system construction device and construction method. The device can be suitable for the construction of a new type of municipal road subgrade drainage system. It has high construction efficiency and precise positioning, does not require frequent installation and replacement of templates, and the quality of the finished product is more guaranteed.

When the construction device of the present invention is operating, the vehicle body 1 moves along the outer edge of the groove according to the planned path, and the distance measuring mechanism 3 and the positioning mechanism 4 cooperate to adjust the travel direction, so that the vehicle body 1 is parallel to the center line of the road and the spacing is consistent; the feed bin 6 receives the concrete material, and injects the corresponding amount of concrete into the skateboard mold through the flow control mechanism 7 to form; the distance measuring mechanism 3 and the positioning mechanism 4 cooperate to correct the travel path, and the height measurement mechanism 5 adjusts the height of the skateboard mold, so that the position of the formed roadbed drainage ditch is accurate; every time 200m of roadbed drainage ditch is laid, the transmission mechanism 8 drives the blade group 9 to descend, digs out a groove 11 on the finalized concrete, the blade group 9 brings the cut concrete back, and the transmission mechanism 8 rotates to pour the concrete into the discharge bin, recovers the concrete, and repeats the above steps until the drainage ditch is laid. The construction device of the present invention adopts slipform construction to realize the continuous sliding of the skateboard mold and the continuous pouring of concrete, which significantly shortens the construction period, and its positioning is accurate, which can ensure the high precision of the size and high surface finish of the concrete component, saving the overall cost.

[0045] In the embodiment of the present invention, the vehicle body 1 is an AGV vehicle, which is provided with a control unit. The control unit integrates artificial intelligence, information processing, and image processing. It can move automatically according to the planned path as needed. A crawler walking mechanism is provided at the bottom, so that the vehicle body 1 has good load-bearing performance and high passability.

[0046] The distance measuring mechanism 3 is used to detect the distance between the vehicle body 1 and the center line of the road, so as to adjust the traveling direction of the vehicle body 1, and includes a mounting bracket 301 and a first distance measuring device 302 and a second distance measuring device 303 provided at both ends of the top of the mounting bracket 301.

[0048] The lifting mechanism 2 is fixedly arranged on the side of the vehicle body 1, and includes a connecting bracket and a hydraulic rod arranged in the vertical direction. The hydraulic rod is communicated with the control unit. One end of the connecting bracket is fixedly connected to the hydraulic rod, and the other end is used to fix the flow control mechanism 7. Under the control of the control unit, the hydraulic rod drives the connecting bracket to move up and down, so that the skateboard mold at the bottom of the flow control mechanism 7 is displaced to a specified height in the vertical direction.

[0049] The flow control mechanism 7 is fixedly connected to the lifting mechanism 2, and includes a flow control valve. The flow control valve is in communication with the control unit.

[0051] The skateboard mold is arranged at the bottom of the flow control mechanism 7. The flow control mechanism 7 adjusts the concrete output flow and inputs it into the skateboard mold. The concrete is extruded and molded by the skateboard mold. When the vehicle body 1 drives the skateboard mold to move, the exterior of the molded concrete is smoothed and finished to ensure the dimensional accuracy and surface finish of the ditch body 10 components.

[0052] The elevation measuring mechanism 5 is arranged on the skateboard mold, and is connected to the control unit for communication. It measures the elevation of the skateboard mold in real time and uploads the detection data to the control unit. If the elevation does not match the design, the height of the skateboard mold is automatically adjusted by the lifting mechanism 2. During operation, the elevation of the skateboard mold is detected in real time by the elevation measuring mechanism 5, and under the control of the control unit, the lifting mechanism 2 automatically adjusts the vertical height of the skateboard mold so that the inclination of the formed ditch body 10 meets the design requirements, and the drainage can flow out smoothly along the ditch body 10 in the later stage.

The rotating assembly drives the blade assembly 9 to rotate, so that the blade assembly 9 is vertically aligned with the groove body 10 or rotated upward to align with the feed bin 6. The hydraulic transmission assembly provides hydraulic power to the blade assembly 9, driving the blade assembly 9 to cut the groove 11 on the groove body 10.

[0054] The blade group 9 is used to cut out the groove 11 and take out the concrete. It includes a vertical blade and an inclined blade. The hydraulic transmission component drives the vertical blade and the inclined blade in sequence to cut into the formed concrete, so as to cut out a right-angled triangular prism-shaped groove 11, and enclose and seal it to take out the cut concrete.

[0056] Compared with traditional formwork casting, the drainage system construction device of the present invention adopts full-automatic numerical control technology to achieve continuous sliding of the skateboard mold and continuous casting of concrete, which significantly shortens the construction period, reduces the number of times the formwork is disassembled and assembled, and reduces labor intensity.

[0075] Example 3

[0076] like Figure 4-6 As shown, the present invention also provides a new municipal road subgrade drainage system, which is obtained by the construction method described in Example 2, and includes a ditch body 10, a groove 11, a water reservoir 13 and a garbage separation component. The ditch body 10 is a trough structure, with multiple groups of grooves 11 on it, and the adjacent grooves 11 are spaced 200 meters apart. The water reservoir 13 is located 0.5 meters downstream of the groove 11, and is connected to the ditch body 10 through a siphon 12, and the accumulated rainwater is discharged into the ditch body 10 to flush the debris. The garbage separation component is used to separate and collect debris in the drainage ditch, and includes a collection frame 14, a lifting rod 15 and a filter baffle 16. The collecting frame 14 is a triangular prism structure, which is compatible with the structure of the groove 11. It is placed in the groove 11 to collect debris such as soil, garbage, and leaves.
