Road surface water seepage performance detection device

Abstract

The invention relates to a pavement water seepage performance detection device. In the prior art, a detection device is poor in sealing effect, manual water supplementing is needed for each time of detection, work efficiency is low, and operation is complex. The invention just aims to solve the above problems in the prior art. According to the technical schemes, the pavement water seepage performance detection device comprises a machine body and a detection device; the detection device comprises a base; a measuring cylinder is arranged in the base; a partition plate is arranged in the measuring cylinder; a water outlet hole is formed in the center of the partition plate; a movable rod with the lower end penetrating through the water outlet hole is arranged in the measuring cylinder; a sealing plate is arranged at the lower end of the movable rod; the diameter of the movable rod is smaller than that of the water outlet hole; a pressing plate is arranged above the measuring cylinder; theupper end of the movable rod penetrates through the top wall of the measuring cylinder and is fixedly connected with the pressing plate; a first spring is connected between the pressing plate and theupper end face of the measuring cylinder; a telescopic oil cylinder is arranged on the machine body; a piston rod of the telescopic oil cylinder is connected with the pressing plate. The device of the invention is compact in structure, convenient to use and accurate and effective in detection.

Description

technical field [0001] The invention relates to the technical field of pavement construction quality detection, in particular to a pavement water seepage performance detection device. Background technique [0002] In the field of road construction, it is often necessary to detect the quality of the road in time. There are many inspection indicators for the quality of road pavement pouring, such as flatness, compaction and water permeability. During the laying of asphalt pavement, one of the basic The point is that it can seal the infiltration of rainwater, ensure the quality of the pavement, and avoid the internal structure of the pavement from being easily damaged due to infiltration of rainwater. Therefore, it is necessary to detect the water seepage coefficient of the pavement after construction in time, and find out problems in time and repair them. [0003] In the process of testing the water permeability of the existing pavement, the usual practice is to close an area ...
