Waste plastic pavement structure for slow traffic system and greenway in city and construction method

Abstract

The invention discloses a waste plastic pavement structure for slow traffic systems and greenways in cities and a construction method. The waste plastic pavement structure comprises a foundation and alower bearing layer, wherein a plastic plate layer is laid on the lower bearing layer; the plastic plate layer consists of two layers, namely an upper plastic plate layer and a lower plastic plate layer; any one plastic plate in the upper plastic plate layer is fixed with two plastic plates in the lower plastic plate layer in a lap joint manner through bolts in a longitudinal direction; the plastic plates are prefabricated; the lower bearing layer is subjected to cement soil stabilization treatment; soil and cement are uniformly stirred, laid on the foundation and are grinded and flattened; the plastic plates are mounted; and soil is piled up on edges of the pavement structure. As the plates are made of waste plastic, and the plastic plates are connected through bolts to form a stable entity, people and bicycles can pass through, and slow traffic systems and greenway pavements in cities can be replaced.

Description

technical field [0001] The invention belongs to the field of civil engineering, and more specifically relates to a waste plastic pavement structure used for urban slow traffic systems and greenways. Background technique [0002] According to statistics from the United Nations, more than 8 million tons of plastic waste are dumped into the ocean every year. If this trend continues, by the middle of this century, the total amount of plastic in the ocean will exceed the sum of fish. The continent" is more than twice the size of Texas. In 2016, the output of my country's plastic products reached 77.17 million tons, while the total amount of recycling was only 18 million tons, and 7.354 million tons still needed to be imported. my country's plastic industry is still in a state of low recycling and high imports. Compared with developed countries, there is still There is a big gap, and there is a lot of room for development in the recycling of waste plastics. [0003] At present, t...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art, aim at the problem of environmental damage and pollution caused by waste plastics being difficult to degrade, and provide a waste plastic pavement structure and construction method for urban slow traffic systems and greenways, waste plastics Various hot-melt plastics or resins can be used, by adding a certain amount of glass fiber, flame retardant, colorant, pouring gravel with a certain particle size, and then connecting each other by bolts to form a continuous plastic pavement structure
