example 1

[0042] The composite roadbed was used for field tests in a contract section of Qinglin Expressway. The roadbed elevation of this section is 5.5m, the layout of the tires is equilateral triangle, the center distance of the tires is 1.6m, and the belt-shaped connectors made of polyvinyl chloride polymer materials 4 Bind and connect the potted tires into a net shape, and fill the gravel with a height of 20cm. The treatment results show that after 3 years of subgrade construction, there is no slope collapse phenomenon, and the soil moisture content in the lower part of subgrade 5 is low, which shows that this form of subgrade 5 plays a very good role in reinforcement and drainage, and improves 5 stability.

example 2

[0044]Shandong Provincial Highway S103 is located in the yellow plain area, where the groundwater level is relatively high. In order to ensure the stability of the subgrade 5, composite tires and crushed stones are used to treat the subgrade 5 in some areas. The design elevation of the subgrade 5 in the treatment section is generally 4.5m~6.5m m, the layout of the tires is an equilateral triangle, the center distance of the tires is 1.5m, and the belt-shaped connectors 4 made of polyvinyl chloride polymer material are used to bind and connect the basin-shaped tires into a network, and the gravel 3 is filled to a height of 25cm. The treatment results show that after 5 years of road operation, the slope has no landslide phenomenon, the water content of the soil below the gravel 3 cushion is high, and the water content of the subgrade soil above the gravel 3 cushion is low, the bottom of the subgrade 5 is very stable, and the road surface There is no deflection phenomenon, which s...

Abstract

The invention discloses a compound tire-broken stone anti-skid draining roadbed structure and a construction method thereof. The compound tire-broken stone anti-skid draining roadbed structure comprises waste tires, connecting pieces and broken stones; the construction method comprises the steps of placing longitudinally cut waste tires at the positions of vertexes of an equilateral triangle sequentially, connecting by the connecting pieces sequentially, embedding on a foundation, filling the broken stones inside the equilateral triangle and in the tires, and then filling a soil road bed on the broken stones. According to the compound tire-broken stone anti-skid draining roadbed structure, the waste tires are distributed at the bottom of the roadbed to replace partial soil masses, the friction force of the soil mass and the waste tire or the contact friction force between the broken stones and the tire is remarkably higher compared with the friction force inside the soil masses, the cohesive force or the internal friction angle of the soil mass (no matter for cohesive soil or non-cohesive soil) is increased, and the stability of the roadbed slope is improved.

Description

technical field [0001] The invention relates to the field of road engineering, in particular to a composite tire-gravel anti-slip and drainage subgrade structure and a construction method. Background technique [0002] In recent years, with the gradual improvement of people's living standards and the rapid development of the logistics industry, the number of private cars and trucks in my country has increased year by year. The increase in the number of vehicles has driven the development of the economy. At the same time, the consumption and wear of automobile tires has also produced a lot of garbage - waste tires. The "black pollution" formed by more and more waste tires is threatening the living environment of all human beings. At present, there are many ways to recycle waste tires as resources. The main ways of reuse are: heat energy utilization, thermal decomposition, production of reclaimed rubber, etc. Among them, the application of waste tires in road construction is t...
