Description

TECHNICAL FIELD

[0002] The roadbed drainage ditch is a crucial drainage facility in roadbed engineering, and its main function is to collect and discharge the accumulated 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 collapse, and avoid road surface damage and traffic safety hazards caused by accumulated water.

[0003] The traditional roadbed drainage ditch is prone to accumulation of debris such as silt, leaves and garbage carried by rainwater due to its open-air characteristics, causing blockage and affecting drainage efficiency, and even leading to water accumulation and flooding. The roadbed drainage ditch is constructed by using the traditional formwork pouring method, which has the following shortcomings: the traditional formwork pouring method requires installation of formwork first, then pouring of concrete, removal of the formwork after the concrete reaches a certain strength, and then repeating the above process at the next location, which is time-consuming and has low construction efficiency. The traditional formwork method requires frequent disassembly and assembly of the formwork, which not only increases the demand for manpower, but also increases the labor intensity. Although the initial investment of the traditional formwork method may be low, the overall labor cost, equipment rental cost and time cost are increased due to the low construction efficiency. The traditional formwork method is prone to errors during formwork splicing, disassembly and assembly, affecting the dimensional accuracy and surface finish of the concrete member, and the formwork needs to be positioned, reinforced and adjusted multiple times, which is cumbersome for on-site management.

[0049] The flow control mechanism 7 is fixedly connected with the lifting mechanism 2, and comprises a flow control valve; the flow control valve is in communication connection with the control unit; the flow control valve adjusts the output flow of the concrete under the control of the control unit, so as to accurately control the concrete forming and pouring amount of the ditch body 10, and avoid that the ditch body 10 is not formed due to the insufficient pouring amount, or the surface of the ditch body 10 is formed with a hollow, exposed reinforcement and honeycomb pitted surface due to the overmuch pouring amount.

[0050] The feeding bin 6 is arranged on the top of the flow control mechanism 7, and receives the input concrete from the pump truck. During operation, the concrete pump truck is synchronized with the vehicle body in speed, and sends the concrete into the feeding bin 6, and then the output flow of the concrete is adjusted by the flow control mechanism 7 and input into the slide plate mold, and the concrete pouring is completed by the customized slide plate mold of the roadbed drainage ditch.

[0075] Example 3

[0076] like Figures 4-6 As shown, the present invention also provides a novel municipal roadbed drainage system, which is obtained by the construction method described in Example 2 and includes a ditch body 10, grooves 11, a water reservoir 13, and a garbage separation assembly. The ditch body 10 is a trough-shaped structure with multiple groups of grooves 11, with adjacent grooves 11 spaced 200 meters apart. The water reservoir 13 is located 0.5 meters downstream of the grooves 11 and is connected to the ditch body 10 via a siphon 12. It discharges accumulated rainwater into the ditch body 10 to flush out debris. The garbage separation assembly 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 adapted to the structure of the groove 11. It is placed in the groove 11 to collect debris such as soil, garbage, and leaves. The lifting rod 15 is fixed at the bottom of the collecting frame 14, which makes it convenient for the operator to lift the collecting frame 14 out of the groove 11. The filtering baffle 16 is located on the rear side of the top of the collecting frame 14 to block debris such as soil, garbage, and leaves, so that the debris falls into the collecting frame 14.

[0077] When the new municipal road subgrade drainage system of the present application carries out drainage operation, the water storage tank 13 stores rainwater when it rains on ordinary days, and when the water level reaches the top of the siphon 12, the stored water will be automatically discharged into the ditch body 10 in one breath due to the siphon principle. The strong water flow flushes the soil, garbage, leaves and other sundries in the drainage ditch to the garbage separation assembly 200 meters downstream. When the water flow containing sundries passes through the garbage separation device, the filter baffle 16 of the garbage separation device will block the sundries, and after the water flow passes, the sundries will fall to the collection frame 14 below by gravity. The inclined filter baffle 16 can ensure the maximum retention of garbage sundries. After the collection frame 14 is filled with sundries, the lifting rod 15 can be pulled up to lift out the collection frame 14 and dump the internal garbage.

[0078] Those skilled in the art will readily understand that the above description is only the preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
