Description

Technical Field

[0001] This utility model belongs to the field of highway engineering technology, specifically, it relates to a core sampling device after drilling for highway acceptance. Background Technology

[0002] Highways are roads built according to national technical standards and inspected and approved by the highway authorities, connecting cities, villages, and industrial and mining bases. The highway base course is an important component of a highway. It refers to the main load-bearing layer directly under the asphalt pavement layer and filled with high-quality materials, or the structural layer directly under the cement concrete pavement layer and paved with high-quality materials. Because the highway base course plays a very important role in the overall quality of a highway, the highway authorities need to strictly control its quality. Core sampling of the highway base course is a very important part of this process.

[0003] Currently, after drilling is completed, construction workers use a screwdriver to insert into the sampling seam to cut the core material, then use a clamp to remove the core material, and finally use a ruler to measure the diameter and thickness of the core material. However, this method requires carrying a lot of equipment, which is prone to loss.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A core sampling device for highway acceptance drilling includes a first clamping arm and a second clamping arm; a threaded screw is fixed to the lower end of the second clamping arm, and a base is movably sleeved on the threaded screw; an arc-shaped clamping plate is fixed to both the base and the lower end of the first clamping arm; a measuring component is installed on the first clamping arm for measuring the dimensions of the roadbed core material after core sampling; and a core material prying component is installed on the base for prying the core material after drilling to facilitate subsequent core material clamping.

[0007] In a preferred embodiment of this utility model, the measuring component is a ruler.

[0008] In a preferred embodiment of this utility model, the core material breaking assembly is a pry bar, and the diameter of the pry bar is smaller than the width of the core extraction slot.

[0009] In a preferred embodiment of this utility model, a locking nut is threaded onto the end of the threaded screw extending from the base.

[0010] In a preferred embodiment of this utility model, the lower end of the ruler is detachably connected to the first clamping arm.

[0011] In a preferred embodiment of this utility model, handles are installed on the upper ends of both the first clamping arm and the second clamping arm.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This utility model is a practical combined core sampling device that integrates three methods: core material separation, core material clamping, and core material measurement. It is easy to carry and has better results and higher efficiency.

[0014] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0020] like Figures 1 to 2 As shown, a core sampling device after drilling for highway acceptance includes a first clamping arm 2 and a second clamping arm 4; a threaded screw 6 is fixed to the lower end of the second clamping arm 4, and a base 5 is movably sleeved on the threaded screw 6.

[0021] Both the base 5 and the lower end of the first clamping arm 2 are fixed with arc-shaped clamping plates 3;

[0022] The measuring component, mounted on the first clamping arm 2, is used to measure the dimensions of the subgrade core material after core sampling;

[0023] The core material prying assembly is installed on the base 5 and is used to pry off the core material after drilling, making it easier to clamp the core material later.

[0024] like Figures 1 to 2As shown, the measuring component is a ruler 1, the core material breaking component is a pry bar 8, the diameter of the pry bar 8 is smaller than the gap width of the core cutting slit 9, the threaded screw 6 extends out of the base 5 and is threaded with a locking nut 7, the lower end of the ruler 1 is detachably connected to the first clamping arm 2, and the upper ends of the first clamping arm 2 and the second clamping arm 4 are both equipped with handles.

[0025] The implementation principle of the core sampling device after drilling for highway acceptance in this embodiment is as follows: During use, loosen the locking nut 7, which allows the base 5 and the pry bar 8 to rotate 180°. Then, rotate the locking nut 7 to lock the base 5. Next, insert the pry bar 8 into the core sampling slot 9 to break the core material. Then, rotate the pry bar 8 180° and reset it. Finally, extend the arc-shaped clamping plates 3 at the lower ends of the first clamping arm 2 and the second clamping arm 4 into the core sampling slot 9 to clamp the core material. Then, use a ruler 1 to measure the cross-sectional diameter and thickness of the core material. Measure the core material thickness several times and take the average value.
