Embodiment

[0073] The tire gabion retaining wall of the present invention has a length of 4m, and a single-stage retaining wall has a height of 3m. The size of the base is 4*1.5*0.5m. The tire uses: 215 / 70R15 tires, that is, the tire inner diameter is 70% in inches and the tire width is 215mm. Install it on the base, and use high-strength bolts to connect the tire along the wall with grouting and drive into the horizontal connection anchor rod , Drive in the self-anchored anchor rod, assemble the second layer, the third layer, etc. Finally in the factory according to the mix ratio of cement: water: fine aggregate: coarse aggregate = 1.0: 0.32: 0.92: 2.34, pour recycled concrete into the tire Finally, the soil is backfilled, and the height of the backfill is 0.8 meters.

Abstract

The invention discloses an earth-retaining wall structure composed of waste tire-broken concrete, and a construction method. The earth-retaining wall structure comprises a base, wherein a first earth-retaining wall unit is fixedly connected to the base; multi-layer second earth-retaining wall units are superposed and arranged on the first earth-retaining wall unit; the first earth-retaining wall unit is composed of one-row multi-column first waste tire-concrete units which are connected into one piece; and each second earth-retaining wall unit is composed of one-row multi-column second waste tire-concrete units which are connected into one piece. The earth-retaining wall is mainly composed of waste tires and broken concrete, wherein the tires wrap the outer side of the concrete, and due to the 'hoop effect' of the tires, the strength of the concrete is greatly increased. By applying the two materials to civil engineering in a combination manner, the problem that the tires and the concrete are difficult to degrade is effectively solved; and great economic, environment-friendly and social benefits are achieved.

Description

Technical field [0001] The invention belongs to the category of a new type of retaining wall, and relates to the material composition and connection form of the retaining wall. Specifically, it is a new type of composite retaining wall structure composed of waste tires and broken concrete and a construction method, which can be used for slope reinforcement Support. Background technique [0002] With the rapid development of my country's economic construction, industrial construction has become my country's pillar industry, especially the automobile industry. Honda Motor has begun to gradually enter the world stage as the red flag produced in my country. But at the same time, the number of used tires is increasing. According to statistics, in 2015, the number of used tires in my country was close to 350 million, and the number has increased by double digits every year. my country has become the largest country for used tires. At the same time, due to the rapid development of civi...
