Description

Technical Field

[0001] The utility model relates to the technical field of road construction, and more specifically to a rapid detection and positioning device for a steel mesh protective layer of a road surface. Background Art

[0002] With the booming development of my country's national economy, bridge engineering continues to innovate, and the demand for project quality is increasing. This, in turn, demands higher standards for process quality control and inspection methods during bridge construction. In highway bridge deck paving, a common structural construction consists of an 8-centimeter-thick C40 concrete layer topped with a 10-centimeter-thick asphalt concrete layer. Notably, the C40 concrete layer incorporates D10 cold-rolled ribbed steel mesh for structural strength, while the protective layer of this mesh is set at 3 centimeters to ensure durability and safety.

[0003] The traditional process for installing steel mesh during bridge deck construction involves first laying the mesh, then setting out measurement points on both sides of the bridge deck and drawing elevation lines based on these points. The vertical distance between the lines and the mesh is precisely measured to verify that the cover thickness meets design and construction specifications, ultimately completing the precise positioning and securing of the mesh.

[0004] However, the traditional two-point alignment method not only requires three operators to work together, but is also susceptible to human factors, resulting in relatively large measurement errors and low overall work efficiency. Therefore, exploring more efficient and accurate measurement and positioning technologies has become a key direction for improving bridge deck pavement quality. Utility Model Content

A movable cylinder 28 is slidably set on the part of the frame rod 26 extending out of the adjustment cylinder 24, and the slope detector 3 and the laser alignment transmitter 4 are set on the movable cylinder 28.

[0027] Preferably, a magnetic block 22 is provided on the bottom surface of the base 21 .

[0028] Preferably, a point detection area 51 is provided on the laser detection plate 5 .

[0029] Before paving the steel mesh, mark the top elevation points of the bridge deck on the inside of the guardrail, 5m / point for straight segments and 3m / point for curved segments, and connect the marked points with ink lines. After the steel mesh is paved, hang the cantilever frame 1 on the top of the guardrail, adjust the frame vertical rods 12 and the frame horizontal rods 13, and ensure that the base position of the main frame 11 is within 3cm above and below the ink line.

[0030] Step 2: Adsorb the universal adjustment base 2 onto the lower cantilever of the main frame 11 of the cantilever frame 1.
