Abstract
Description
Technical Field
[0001] The utility model belongs to road construction facilities, and particularly relates to a temporary steel plate road surface structure for roads. Background Art
[0002] During the renovation of urban pipe networks, it is often necessary to excavate the road surface. In order not to affect vehicle traffic, the most common construction measure is to build a temporary steel plate road surface. However, while this temporary steel plate road surface brings convenience, due to its poor overall stiffness, it is often accompanied by noise problems, which have a certain impact on the living environment of surrounding residents, especially during night or early morning hours, and the impact is particularly obvious. In order to reduce the impact on the living environment of surrounding residents, a series of effective solutions need to be taken to reduce the vibration of the steel plate road surface and the generation of noise. Content of the Utility Model
[0003] The purpose of the utility model is to provide a temporary steel plate road surface structure for roads with good overall stiffness and shock absorption effect.
[0004] The technical solution adopted to achieve the purpose of the utility model is as follows:
[0005] The temporary steel plate road surface structure for roads provided by the utility model includes a square steel pipe support combination as a frame structure and a steel plate fixed on the square steel pipe support combination, and a rubber pad is arranged between the square steel pipe support combination and the steel plate.
[0006] The square steel pipe support combination includes fixing parts located at the four corners of the frame structure and a number of square steel pipes. The fixing parts include vertical notches and horizontal notches perpendicular to the vertical notches, and edges extending horizontally along the side edges of the vertical notches and the horizontal notches. Bolt holes are arranged on the edges. The square steel pipes are respectively placed in the vertical notches and the horizontal notches of the fixing parts. The rubber pad is arranged on the square steel pipes, and the steel plate is arranged on the rubber pad. The steel plate and the rubber pad are fixed on the fixing parts with bolts.
[0007] The steel plate is spliced by multiple pieces. Advantageous Effects
[0008] 1. Compared with the traditional construction method, the utility model can adopt standard industrial parts and be fixed by mechanical connection, and is applicable to trench operations within a width of 2 m.
[0009] 2. By appropriately adjusting the overlapping width of the new and old road surface layers, the overlapping width of the asphalt concrete surface layer is adjusted from ≥0.15 m to ≥0.5 m, ensuring that the square steel pipes are placed on the road base, and the elevation difference between the steel plate surface layer and the road surface layer is controlled within 10 mm. After installation, during vehicle driving, there is no obvious foreign body feeling, and the impact of the driving vehicle on the edge of the steel plate can be greatly reduced.
[0010] 3. By adding a square steel pipe support combination and rubber pads under the steel plate, the overall stiffness of the temporary steel plate road surface is greatly improved, and the bending deformation at the edge of the steel plate is reduced, thus solving the problems of large vibration and noise generated by the gap between the steel plate and the ground and the joints between the steel plates.

[0020] See Figure 1 —— Figure 4 , during construction, the municipal road 1 is undergoing pipeline network renovation. A trench 2 is excavated, and the asphalt concrete surface layer 11 on both sides of the trench 2 is chiseled. The lap width between the old and new pavement surface layers is adjusted. The lap width of the asphalt concrete surface layer 11 is adjusted from 0.15 m to 0.5 m. A fine sand cushion layer 3 within 10 mm is laid on the road base 12 to play a leveling role. The present utility model is erected on the trench 2 excavated from the municipal road 1. First, the square steel pipe support combination 4 is installed. The longitudinal and transverse square steel pipes 42 are placed on the fixing member 41. The spacing of the square steel pipes 42 perpendicular to the trench direction is 1 m. Except for the wall thickness, the dimensions of the square steel pipes 42 can be combined according to construction needs. A 10-mm-thick rubber pad 5 is laid on the square steel pipes 42. The steel plate 6 is hoisted and placed on the square steel pipe support combination 4. The bolt holes 412 are aligned, and the bolts 7 are tightened to fix the steel plate 6.
