Abstract

A method of recycling the solid waste in road base engineering belongs to the technology field of waste recycling, and solves the problem of the solid waste recycling. The method includes: using waste concrete blocks, waste bricks, waste tiles and waste stones of the solid waste as the major material, crushing into pieces by a crusher, separating the metal substances by a magnetic separator, obtaining two major categories of recycling gradation solid material with granule diameters of 0-30mm and 0-70mm respectively conform to the granule continuous gradation. The recycling gradation solid material with the granule diameter of 0-30mm can be directly used as the base of a road pavement water permeable pavior brick, the packing of a subgrade bedding layer and the filling / exchanging reinforcing material of a soft soil subgrade; the recycling gradation solid material with the granule diameter of 0-70mm can be directly used as the packing of road engineering subgrade stone column replacement. The recycling gradation solid material can be blended with flyash, lime, carbide slag and cement to form different subgrade materials. The advanced method makes full use of the resources, and is applicable to recycling all solid waste into recycling gradation solid material and further to the road construction, which offers a promising prospect of popularization.

Description

technical field

[0001] The invention belongs to the technical field of waste utilization, a method for regenerating waste solids and using them for road bases. Background technique

[0002] With the rapid development of the world economy, especially the increasing progress in the comprehensive utilization of waste resources, the technical requirements for the recycling of waste solids are becoming more and more urgent. In the known technology, the existing waste solids such as waste bricks, waste tiles, waste stones, waste concrete blocks, etc., are mainly used to fill the building foundation and then compacted, and most of them are transported to the suburbs and villages for open-air stacking. deep landfill etc. This not only takes up land resources, but also causes serious environmental pollution, and wastes garbage removal and transportation costs, especially burying hidden dangers for future generations. Therefore, the recycling of waste solids is a difficult problem t...
