When the measuring device is used, the base 10 is stably placed on the same plane as the height of the bottom of the water stabilization layer, the measuring piece is slid in the direction away from the base 10, the measuring piece is gently placed on the top surface of the water stabilization loose layer, and the loose layer thickness is determined according to the scale mark on the corresponding vertical rod 20 of the measuring piece at the moment.
By adopting the technical scheme, in the paving process, workers can measure the loose thicknesses of different points by utilizing the cooperation of the vertical rod 20 and the measuring piece, compare the measured values to know whether the level loose thickness is uniform and compliant, find problems in time and correct the problems, and compared with the prior art, the method has the advantages that the steel wire rope datum line is not required to be installed, the measuring operation is simplified, the error caused by low accuracy of the thickness detection datum can be avoided, and the one-time construction qualification rate is improved.
In a practical embodiment, the sliding sleeve 50 is coaxially sleeved on the alignment rod 20, one end of the measuring member is connected to the outer wall of the sliding sleeve 50, and the bottom of the other end is flush with the bottom of the sliding sleeve 50. Because when detecting the loose thickness, the measuring part can be generally far away from the erector rod 20, the sliding sleeve 50 can enable the measuring part to slide relative to the erector rod 20, and compared with direct connection, the sliding sleeve 50 can also increase the contact area between the measuring part and the erector rod 20 and improve the connection stability of the measuring part and the erector rod 20. During measurement, the height of the bottom of the measuring piece, namely the water-stable loose thickness, can be directly obtained according to the scale marks on the vertical rod 20 corresponding to the bottom of the sliding sleeve 50, and the reading operation is simple, convenient and accurate.
To ensure connection stability, the sliding sleeve 50 should have a proper length, and to ensure that the bottom of the measuring element is flush with the bottom of the sliding sleeve 50, the measuring element in this embodiment includes an L-shaped rod 30 and a positioning plate 40, the positioning plate 40 is disposed at the end of the L-shaped rod 30 far from the sliding sleeve 50, and the positioning plate 40 is perpendicular to the leveling rod 20.
