Solidified soil plant mixing treatment method and equipment thereof

Abstract

The invention relates to a solidified soil mixing method and equipment in highway construction and particularly relates to a solidified soil plant-mixing treatment method and equipment thereof. The method is characterized in that: raw soil is stored in a feeding hopper, after the raw soil is discharged in the feeding hopper, the raw soil is conveyed to a crusher through a first conveying belt, meanwhile, a lime powder bin conveys lime powder to the first conveying belt through a first spiral conveyor, the raw soil is covered with the lime powder, and the lime powder and the raw soil are conveyed into the crusher together; after the crusher performs preliminary crushing treatment and mixing on the mixture of the original soil and the lime powder, the crusher discharges the mixed sandy soilof the original soil and the lime powder to a second conveying belt through a distributor; and the second conveying belt conveys the mixed sandy soil to a soil covering field for soil covering treatment for 48 hours or longer, thus sanding original soil; and when the transport cart transports the sandy soil into the feeding hopper for discharging, the sandy soil is more uniform and smooth, and thesandy soil is easier to crush during crushing treatment.

Description

technical field [0001] The invention relates to a solidified soil mixing method and equipment in road construction, in particular to a solidified soil factory mixing treatment method and equipment thereof. Background technique [0002] With the continuous large-scale construction and maintenance of highways and urban roads in our country, natural sand and stone resources are increasingly scarce and exhausted, and environmental protection requirements in various places are constantly improving, and the production of machine-made sand is also strictly restricted, resulting in resource shortages for construction materials. dilemma. The shortage of raw materials has triggered a rise in the price of concrete products, further increasing construction costs, and further compressing construction profits. Relying on artificial synthetic materials to replace natural materials and solving the dilemma of basic materials is a major issue facing my country's construction industry. At pre...

Problems solved by technology

The main raw material of solidified soil is soil or lime soil (lime soil refers to the product obtained after sedimentation and pressure filtration of waste mud water). During the preparation process, it is necessary to mix soil or lime soil with a small amount of cement and add a certain amount of soil curing agent. Therefore, when feeding soil or lime soil, due to its high viscosity, the soil cannot be fed in the feeding hopper, which will cause the blockage of the feeding hopper, which will affect the normal feeding. At present, the feeding hopper is used The way of setting the screw rod at the lower end is to assist the feeding of the soil. This feeding method is not effective, and the soil or lime will adhere to the screw rod, and the phenomenon of blocking the feeding port will still occur; Unevenness will lead to uneven delivery of the soil to the hopper, sometimes more and sometimes less, so that the weight of the soil cannot be accurately weighed, and the subsequent mixing of the soil with curing agent and cement will cause errors, and due to the viscosity of the soil It will be agglomerated, and the existing crushers are not effective in crushing soil, which will make soil clods with a diameter greater than 50mm be mixed into the original soil material, which will eventually affect the quality of the solidified soil
