Description
Technical Field
The invention relates to the technical field of brick making, in particular to a preparation process for building residue soil recovery brick making.
Background
With the rapid development of cities in China, bottlenecks restricting the development of cities are increasingly remarkable while the scales of the cities are continuously enlarged. Taking Shenzhen as an example, Shenzhen speed achieves the attention achievement, however, a large amount of residual muddy soil becomes a worry in urban growth. With the operation of the whole line of projects such as a subway, the residual muddy soil generated in Shenzhen city in one year exceeds 2000 ten thousand tons, and the storage fields in the whole city are 151, wherein 145 of the storage fields are full, only 6 of the storage fields are left except the red down storage field with the photophobic event, and the remaining storage capacity is about 1600 ten thousand cubic meters, so that the storage field is difficult to maintain for one year. A large amount of residual sludge and dregs can cause a plurality of problems during standby: for example, the storage site of the residual soil and the residual soil needs a lot of space, and the conventional consumption points are selected in suburbs, so that not only can the cultivated land be damaged, but also the local ecological environment is influenced. In addition, the air pollution problem, dust in the residual mud and residue soil enters air along with wind, and the urban air quality is influenced. If the residual sludge soil is continuously dredged in a mode of piling, filling or being used as road bed filler, not only a large amount of land resources are occupied, but also the development of urban economy and the sustainable development of the building industry are seriously limited.
