Description

Technical Field

[0001] The invention relates to the technical field of highway maintenance equipment, in particular to a highway pavement performance detection and collection device. Background Art

[0002] The main reasons why roads need to be tested for pavement performance are as follows: Ensure the feasibility and quality of the construction plan: Through pavement performance testing, the applicability of construction methods and materials can be verified before actual construction, thereby ensuring the quality of the project. In addition, testing can also evaluate the quality of construction and ensure that materials and structures meet design requirements and standard specifications; Timely discovery of quality problems and avoidance of secondary construction: pavement performance testing can timely and accurately discover quality problems in road projects, thereby effectively avoiding secondary construction and ensuring the overall safety of road projects; Supervision and management of construction technology quality: pavement performance testing helps to effectively supervise and manage construction technology quality, making highway engineering projects more scientific and reasonable, and promoting the innovation and progress of road engineering technology; Evaluate material performance and quality: Inspections can evaluate the performance and quality of materials and make necessary adjustments and improvements to ensure the life and stability of the road; Ensure traffic safety: Road performance testing also includes testing of road surface flatness, skid resistance, water immersion resistance and other parameters, which are crucial to road safety and traffic efficiency. Especially in severe weather conditions, road performance testing is particularly critical to reducing traffic accidents and improving road capacity; In summary, pavement performance testing plays a vital role in highway engineering. It not only ensures the quality and safety of highways, but also improves traffic efficiency and reduces maintenance costs, thus bringing long-term benefits to society and the public.

[0003] The road pavement performance test includes the test of the road pavement's water resistance and water permeability. The conventional test method is to place and seal a test tube on the surface of the road, then pour the test water into the test tube, the water will contact the road surface through the test tube, and then observe the test tube. The surface of the test tube is provided with a scale, and regular inspections are performed every sixty seconds or five minutes to observe the rate at which the water in the test tube drops, so as to obtain the water permeability parameters and water resistance on the road surface. However, this test usually requires a group of three to assemble, and after the assembly, the fixed-point test is performed, and then the test is disassembled and continued on the road ahead. This will require more manpower and time for the entire test. For this reason, we propose a road pavement performance detection and collection device. Summary of the invention

When in use, only one person needs to sit in the main driving seat of the towing pickup truck to operate the device. The camera transmits wireless signals to a display, which is directly installed on the auxiliary driving seat of the towing pickup truck, so that the observer sitting in the main driving seat can observe the transparent tube in the vehicle. When the towing pickup truck is driven to the collection location, the air pump is turned on. The air pump can pressurize the main water tank, so that the water in the main water tank can enter the auxiliary water tank under pressure. The weight of the auxiliary water tank increases due to the increase in the amount of water, so that the weight of the auxiliary water tank exceeds the supporting force of the damper to bounce upward, and the auxiliary water tank can drive the transparent tube downward. Move the trailer so that the hollow sealing pad contacts and fits tightly against the road surface under the trailer. Then, the drain pipe is opened by remote control so that the water in the auxiliary water tank can be poured into the transparent pipe. When the water level reaches the position that the camera can observe, the drain pipe is closed. At this time, the staff can sit in the main driver's seat and observe the water seepage rate of the road surface. When it is necessary to leave, the air pump reverses the air pump to make the main water tank into a negative pressure state, so that the water in the auxiliary water tank is pumped back into the main water tank. After the weight is reduced, the damper can push the transparent tube and the auxiliary water tank back to their original position, and drive the towing pickup truck to the next collection site. The entire detection process only requires one person to operate, and there is no need to get off the vehicle. At the same time, the deployment and movement are more flexible, which solves the problem of requiring more manpower and time for the entire test.

[0013] The present invention cooperates between support rods, top plates, photovoltaic panels, reflective strips, shielding plates, guardrails and warning signs. The support rods can provide support for the top plates and photovoltaic panels, the photovoltaic panels can generate electricity to provide electricity for the air pump, and at night, the air pump can be directly connected to the on-board power supply of the towing pickup truck. The photovoltaic panels and the top plates can block sunlight and reduce direct sunlight on the transparent tube, so as to reduce the deviation of detection data caused by water evaporation in the transparent tube. The guard plates and shielding plates can form a temporary storage area for storing roadblocks, cones and other highway warning equipment. The reflective strips and warning signs can provide warnings to vehicles behind day and night. BRIEF DESCRIPTION OF THE DRAWINGS
