Problems solved by technology

Abandoned roads will become useless construction waste, resulting in a waste of resources, which also violates the goal of energy conservation and emission reduction in my country, and increases the difficulty of controlling energy conservation and emission reduction goals
Therefore, the existing mode or structure of building temporary pavement is still not ideal enough to meet the needs of use.

Embodiment

[0029] In this example, the detailed design is carried out through the mechanical analysis of the steel plate pavement, and a temporary steel plate pavement unit is designed according to the mechanical analysis. The pavement unit is composed of a group of parallel shock-absorbing and sound-absorbing strips welded to the bottom of a square steel plate with a thickness of 20mm and a side length of 2 meters. The shock-absorbing and noise-absorbing strip is a steel strip with a trapezoidal cross-section folded from a steel plate with a thickness of 6mm. A group of parallel shock-absorbing and noise-absorbing strips form a wave shape at the bottom of the steel plate. The elastic contact surface transmits the self-weight of the overpressure of the road surface and the load to the ground structure. On the one hand, it can prevent the deformation of the steel plate caused by the heavy pressure of the vehicle, and on the other hand, it can also control the displacement of the road sur...

Abstract

The invention discloses an assembled temporary pavement. The assembled temporary pavement comprises a group of pavement units (1) spliced through connection plates and bolts (2). The width of the pavement is equal to the sum of length of the 2-3 pavement units (1). The length of the pavement is determined according to the construction site. Steel plate pavement standard members with the sizes of 2m*2m*20mm are used and the steel plate pavement standard members are connected through cast steel connection members with thickness of 15mm to form the integral pavement so that crosswise concaving phenomenon is prevented in use. The bottom of the steel plate is provided with a shockproof noise reduction waveform plate, the waveform plate and a ground compacted hard soil layer form an elastic contact surface, and the elastic contact surface transmits ground overpressure self-weight and load to a ground structure, controls pavement displacement, inhibits pavement and ensures pavement safe operation. The assembled temporary pavement utilizes bituminous varnish to prevent rust so that a service life is prolonged.

Description

technical field [0001] The invention relates to an assembled temporary road surface, which belongs to the technical field of temporary road laying on construction sites. Background technique [0002] At the construction site, temporary roads are usually laid to meet the transportation needs. Most of the existing temporary roads use cast-in-place pavement. The cast-in-place pavement is a permanent road and it is difficult to dismantle it. Therefore, it is generally discarded directly after the project is completed. . Abandoned roads will become useless construction waste, resulting in a waste of resources, which also violates the goal of energy conservation and emission reduction in my country, and increases the difficulty of controlling energy conservation and emission reduction goals. Therefore, the existing mode or structure of building temporary pavement is still not ideal enough and cannot meet the needs of use. Contents of the invention [0003] The purpose of the p...
