[0002] In the process of asphalt pavement construction, the thickness of the laid asphalt layer needs to be measured to determine whether the asphalt laying thickness meets the requirements. The prior art usually uses core sampling method or ultrasonic detection and radar thickness measurement when measuring asphalt thickness. Although the above-mentioned methods can provide accurate measurement data, they have high equipment purchase and maintenance costs. For example, the core sampling method requires using a core drill to drill multiple samples before measuring, which causes partial damage to the laid asphalt pavement. Moreover, the large-sized core drill is not easy to move and store, and is not quick and convenient to use, resulting in a significant decrease in the efficiency of asphalt pavement paving thickness measurement. SUMMARY
[0003] The utility model aims to provide a kind of asphalt pavement paving thickness measurement workpiece, and overcome the above-mentioned prior art deficiencies, effectively solve the existing problems of high cost and low efficiency of asphalt pavement paving thickness measurement.

[0006] Further, a protective cylinder is coaxially sleeved on the top end of the drill cylinder, the top end of the protective cylinder is fixedly connected with the outer wall of the handle, and the drill cylinder is slidably connected with the protective cylinder.

[0013] Fig. 2 This is a top view of the present invention;

[0015] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings:
[0016] like Figs. 1-2 As shown, an asphalt pavement paving thickness measuring tool includes a drill cylinder 1. A probe 2 is slidably connected to the inner cavity of the drill cylinder 1. The top end of the probe 2 is fixedly connected to a handle 3. A pressure-rebound assembly is provided on the probe 2. The outer end of the handle 3 is flattened, and a through-hole 4 is opened along the length direction at the outer end of the handle 3. A steel ruler 5 is slidably connected to the through-hole 4. The bottom end of the steel ruler 5 is fixedly connected to a strip support 6. The strip support 6 is fixedly installed on the outer side wall of the drill cylinder 1. The pressure-rebound assembly includes a spring 7, which is fitted onto the probe 2. The top end of the spring 7 is fixedly connected to the outer wall of the handle 3, and the bottom end of the spring 7 is fixedly connected to an annular sleeve 8. The annular sleeve 8 is coaxially fixedly installed in the inner cavity of the drill cylinder 1. The probe 2 is inserted into the hollow cavity of the annular sleeve 8. A protective sleeve 9 is coaxially fitted at the top end of the drill cylinder 1. The top end of the protective sleeve 9 is fixedly connected to the outer wall of the handle 3, and the drill cylinder 1 and the protective sleeve 9 are slidably connected.
[0017] Specifically, by quickly inserting the probe 2 in the bit barrel 1 into the not fully solidified asphalt pavement and reading the descending size of the probe 2 on the steel ruler 5, the thickness of the laid asphalt is measured.
[0018] In actual use, the construction personnel holds the handle 3 to vertically place the bit barrel 1 on the measured asphalt pavement and presses down the handle 3 to drive the connected probe 2 below to insert into the asphalt pavement. During the descending of the handle 3, the outer end flattened section of the handle 3 corresponding to the through hole 4 also descends. When the bottom end of the probe 2 meets the hard underlying base, the pressing down of the handle 3 is stopped. At this time, the descending height of the flattened outer end of the handle 3 on the steel ruler 5 is the thickness of the laid asphalt pavement. The flattened outer end compression size of the handle 3 is in millimeter, which can be ignored in the measurement of the laid thickness data of the asphalt pavement. During the measurement, the pressed down handle 3 forces the spring 7 to compress into the inner cavity of the bit barrel 1. When the measurement is completed, the handle 3 is released, and the spring 7 rebounds to reset the handle 3 and drive the probe 2 to pull out from the asphalt pavement, thereby further reducing the working strength of the construction personnel. The protection barrel 9 can protect the construction personnel from being squeezed by the spring 7 when pressing down the handle 3.
[0019] As shown in Figs. 1-2 , an asphalt pavement laying thickness measurement workpiece, a pad 10 is coaxially installed at the bottom end of the bit barrel 1, a insertion hole 11 is coaxially opened on the pad 10, the insertion hole 11 is connected with the inner cavity of the bit barrel 1, the diameter of the insertion hole 11 is the same as the diameter of the probe 2, a plurality of anti-skid protrusions are uniformly arranged on the bottom wall of the pad 10, a gasket 12 is coaxially fixedly installed in the inner cavity of the bit barrel 1, the probe 2 is inserted into the hollow inner cavity of the gasket 12, and the diameter of the hollow inner cavity of the gasket 12 is the same as the diameter of the probe 2.
[0020] Specifically, the pad 10 can make the bit barrel 1 more stable on the asphalt pavement, thereby improving the measurement efficiency.
[0021] In actual use, when the pad 10 is attached to the asphalt pavement, the measurement workpiece can be stably placed on the asphalt pavement, and the bit barrel 1 can be perpendicular to the asphalt pavement, so that the probe 2 is vertically inserted into the asphalt pavement, thereby further improving the measurement accuracy. The diameter of the insertion hole 11 opened on the pad 10 is the same as the diameter of the probe 2, so that the sliding gap between them is minimized and the sliding is more stable. When the probe 2 is retracted into the inner cavity of the bit barrel 1, the circular edge of the insertion hole 11 can scrape off the impurities adhered to the outer circumferential surface of the probe 2. The coaxially fixedly installed gasket 12 in the inner cavity of the bit barrel 1 can make the probe 2 slide more stably.
[0022] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
