Problems solved by technology

[0004] 1. Most of the existing pavement panels are made of earth and stone materials, which not only consume a lot of stone resources, but also crack and damage the road surface. At the same time, the gap between the panel and the roadbed is easy to appear, and the road surface is anti-skid Poor performance, affecting the travel and safety of pedestrians
[0005] 2. The size of the existing sidewalk slab is small, and it takes a lot of man-hours to lay it. The laying efficiency is low, and the technical requirements for the construction personnel are high when laying the road surface. If the construction personnel are not skilled enough, the surface of the paved road will be uneven.
[0006] 3. When setting up the urban pipeline network under the existing sidewalk structure, it is necessary to bury the pipeline and pass the urban pipeline network through the pipeline. This arrangement is not only troublesome for laying the pipeline and installing the pipeline network, but also requires digging the road slab for maintenance of the urban pipeline network. Opening the pipeline is not only a complicated operation process, but also affects the traffic operation on the road for a long time

Embodiment 2

[0040] The difference from Example 1 is that the recycled plastic assembled sidewalk panels based on the arch composite structure in this example have 6 panel structures 1, and the modulus of elasticity is 822Mpa, the length of the panel structure 1 is 100cm, and the arch The horizontal span of the shaped groove 2 is 30m, the arch height is 5cm, the distance from the vault to the upper end surface of the panel structure 1 is 10cm, and the distance between the central axes of the adjacent arched grooves 2 is 50cm; the width of the support column 31 is 3cm , height is 25cm, and the height of support base 32 is 6cm, and width is 5cm of support column width; The modulus of resilience of the subgrade 5 is 35Mpa, and the modulus of elasticity of the recycled plastic is 3500Mpa.

Embodiment 3

[0042]Different from Embodiment 1 and Embodiment 2, the recycled plastic assembled sidewalk panels based on the arched composite structure of this embodiment have 10 panel structures 1, and their elastic modulus is 1016Mpa, and the length of the panel structure 1 80cm, the transverse span of the arched groove 2 is 20m, the arch height is 10cm, the distance from the vault to the upper end surface of the panel structure 1 is 20cm, and the distance between the central axes of adjacent arched grooves 2 is 30cm; Width is 2cm, and height is 30cm, and the height of supporting base 32 is 10cm, and width is 5cm of support column width; The modulus of resilience of the subgrade 5 is 60Mpa, and the modulus of elasticity of the recycled plastic is 3800Mpa.

[0043] The panel structure 1 of Embodiment 1, Embodiment 2 and Embodiment 3 is prefabricated in a plastic prefabrication factory. The prefabrication process is as follows: the temperature of the prefabricated factory building is contr...

Abstract

The invention provides a recycled plastic assembled sidewalk panel based on an arch-shaped combined structure and a paving method thereof, and belongs to the technical field of road engineering construction. The recycled plastic assembled sidewalk panel specifically includes a panel structure, a plurality of arch-shaped grooves are formed in the lower end face, opposite to a roadbed, of the panelstructure, the cross sections of the arch-shaped grooves are in inverted-U shapes, and half-I-shaped supporting units for supporting the panel structure are arranged on the two sides of the lower portions of the arch-shaped grooves. The panel structure is prefabricated from recycled waste plastic. The paving method is simple in operation, the surface is smooth, and certain sliding resistance is achieved.

Description

technical field [0001] The invention belongs to the technical field of road engineering construction, and in particular relates to a recycled plastic assembled sidewalk panel based on an arched composite structure and a laying method thereof. Background technique [0002] Plastic can be seen everywhere in our daily life. Its invention greatly facilitates our daily life, but it takes a long time to degrade waste plastic. If it is not handled properly, it will seriously pollute people's living environment. Therefore, for waste plastic Plastic recycling has always been a topic of concern. [0003] my country's cities are densely populated, especially in economically developed areas, where the population is even denser. The requirements for the construction and maintenance of urban pedestrian roads are constantly increasing. At present, the construction of urban roads still has the following problems: [0004] 1. Most of the existing pavement panels are made of earth and stone ...
