AI Technical Summary

Technical Problem

In existing EICP technology, the urease extraction process is too complicated, the enzyme solution has a short preservation time, the construction is complicated, and the cost is high, which is not conducive to large-scale engineering applications.

Method used

Plant seeds are used to reinforce the foundation material. The seed powder is soaked in the leaching solution to form a suspension and then filtered. The filtrates are combined and reacted with urea and calcium chloride solution to simplify the extraction process and extend the preservation time of the enzyme solution.

Benefits of technology

It simplifies the urease extraction process, reduces costs, extends the preservation time of enzyme solutions, is suitable for large-scale engineering applications, and uses environmentally friendly and pollution-free materials.

Abstract

The application discloses a kind of plant seed reinforced ground material and ground reinforcing method, belong to ground reinforcing technical field.The above-mentioned plant seed reinforced ground material includes plant enzyme supernatant and reaction liquid;Wherein, the plant enzyme supernatant is prepared by the following method: seed dry powder is immersed in leaching solution, stirring forms suspension after being placed, and filtrate and supernatant I are obtained by filtration;The obtained residue is immersed in leaching solution again, stirred and placed, and supernatant II is collected by filtration, and supernatant I and supernatant II are uniformly mixed to be prepared;Reaction liquid is urea and calcium chloride mixed solution.In the application, raw materials used are less, and the raw materials involved do not contain acetone and other chemical solvents, and filter cloth and other consumables and by-products such as residue can be recycled, which realizes true renewable and pollution-free in raw material use;The preparation process is simple, and centrifugation and other plant enzyme extraction processes are not required, which can save a lot of manpower and financial resources, and is helpful to large-scale application of EICP technology.
