Prefabricated roadbed with blocks formed by solidifying and sealing of solid waste and poor soil

Abstract

The invention discloses a prefabricated roadbed with blocks formed by solidifying and sealing of solid waste and poor soil. The prefabricated roadbed is characterized in that the prefabricated roadbedcomprises the multiple solidified and sealed prefabricated blocks; the multiple solidified and sealed prefabricated blocks are assembled and subjected to interlayer bonding through geogrids or geotextiles; each solidified and sealed prefabricated block comprises a sealed bag used for containing the solid waste or the poor soil; the sealed bags are provided with extraction openings which can adjust the compactness of the solidified and sealed prefabricated blocks; and each sealed bag comprises a face layer and a waterproof layer, and the waterproof layers are arranged on the inner sides of theface layers. The sealed bags are filled with the solid waste or the poor soil for solving the solid waste and poor soil roadbed filling problem; and the solidified and sealed prefabricated blocks areassembled into the prefabricated roadbed, thus the overall strength and the bearing capability of a foundation are improved, differential settlement of the constructed roadbed is effectively controlled, and the engineering quality problem that in the prior art, a roadbed is insufficient in stability, and consequently road surface cracking is prone to occurring is solved.

Description

technical field [0001] The invention relates to the technical field of highway and urban road construction, in particular to a prefabricated and assembled roadbed in which solid waste and poor soil are solidified and packaged into blocks. Background technique [0002] With the rapid development of the economy and the rapid development and utilization of mineral resources, a large amount of industrial waste residues have been produced. The acceleration of urbanization in my country and the initiation of large-scale shantytown renovation projects in urban areas have produced a large amount of construction waste residues. The accumulation of large amounts of domestic waste has also produced a large amount of domestic waste. These solid waste and domestic waste urgently need to be resourced and recycled; my country has a wide range of bad soils (saline soil, soft soil, expansive soil, etc.) , loess, silt soil) distribution areas, in the construction of highway projects in these un...
