Pavement structure depth detection device
The invention relates to a pavement structure depth detection device. Detection cylinder, the detection barrel comprises a barrel body, a rigid barrel cover arranged at the top of the barrel body andan inner side elastic film arranged at the barrel bottom; cylinder body vertical arrangement, an outer side elastic film is arranged at the periphery of the inner side elastic film; a measuring cavityis defined by the inner side elastic film, the barrel body and the barrel cover; the pavement structure depth detection device further comprises a liquid injection device used for pumping pressure liquid into the measurement cavity and a metering structure used for metering the volume of the liquid pumped into the measurement cavity, and further comprises an annular pressing block which can moveup and down relative to the cylinder and is used for applying pressure to the outer side elastic film. According to the invention, the problem of inaccurate structure depth detection easily caused bythe fact that the area of a measuring point cannot completely cover a pit in the prior art is solved.
本发明涉及一种路面构造深度检测装置，包括检测筒，检测筒包括筒体、设置于筒体顶部的刚性桶盖和设置于桶底的内侧弹性膜，筒体竖向布置，内侧弹性膜外围设置有外侧弹性膜，内侧弹性膜、筒体和桶盖围成测量腔，路面构造深度检测装置还包括用于向所述测量腔泵入压力液体的注液装置和用于计量泵入所述测量腔内液体体积的计量结构，路面构造深度检测装置还包括相对所述筒体可上下移动的用于对所述外侧弹性膜施压的环形压块。本发明解决了现有技术中测点面积无法完全覆盖凹坑而容易导致的构造深度检测不准确问题。
