Description

Technical Field

[0001] The utility model relates to a device for detecting water permeability of road base materials, belonging to the technical field of material detection. Background Art

[0002] The pavement base is a layered structure that is paved in layers on the roadbed surface with a single material according to certain technical measures. The quality of its materials and quality directly affects the quality and performance of the pavement. The base is the load-bearing layer of the entire road and plays a role in stabilizing the road surface. The pavement base is divided into an inorganic binder stabilized base and a crushed and gravel base.

[0003] The existing patent number is CN217765982U, which is a road base material water permeability detection device. It uses four clamping components to fix the road base material test block, and the front end surface of each fixed side plate is provided with a flexible plastic pad to facilitate the fixed side plate to fit with the road base material test block, avoid water leakage from the gap between the road base material test block and the fixed side plate during detection, and improve the authenticity of the detection result. The water in the water storage tank is sprayed to the upper surface of the road base material through the nozzle, and the receiving box receives the water that passes through the road base material test block for detection. However, this device needs to be continuously supplied with water when in use, and does not have a water source filtering device, which is easy to cause water waste in the process of detecting a large number of different materials. In addition, the road base is not a fastened block, but is made of loose materials, and thus the materials of different road bases have different compactness, and thus it is difficult to perform corresponding water permeability detection according to the different compactness during the detection process, thereby reducing the accuracy of the water permeability detection.
