Soil improvement process based on separate doping method

Abstract

The invention discloses a soil improvement process based on a separate mixing method. The soil improvement process comprises the following steps: step 1, dividing collected engineering residue soil reclaimed materials into cohesive soil, sandy soil and gravelly soil; 2, quantitatively conveying the collected and classified cohesive soil, sandy soil and gravelly soil into a crushing and screening device, and crushing and screening to obtain raw materials with the particle size being smaller than 20 mm; 3, conveying the raw materials obtained in the step 2 into a mixing and curing device, adding a curing agent and water, and mixing to obtain a finished product material with the water content of 18-25%; and step 4, performing image acquisition on the mixed finished product material through an image acquisition device, and processing feedback information of the image acquisition device by a control device so as to judge whether the particle shape and the particle size of the finished product material meet requirements or not. And the blending amount of various types of soil is adjusted in real time according to a detection result, and finally the improved soil meeting the quality requirement is continuously and stably produced.

Description

technical field [0001] The invention belongs to the field of engineering slag soil treatment and soil restoration, and particularly relates to a soil improvement process based on a sub-mixing method. Background technique [0002] At present, with the development of the construction industry, more and more urban construction is increasing, and at the same time, a large amount of construction waste is generated, and most of these construction wastes are currently treated by landfill and consumption. , which not only destroys the ecological environment, but also affects the appearance of the city and other issues. [0003] In the process of using the existing soil improvement technology, due to the complex composition of the soil, unstable moisture content, and high impurity content, it cannot be directly treated. The subsequent improvement process can only be carried out after the “smouldering” treatment. The entire “smouldering” process requires a lot of manpower and materia...
