  • Patent number: 11827914
    Abstract: The present invention belongs to the technical field of rock and soil reinforcement, and specifically relates to a plant urease-containing soil solidification agent and a zero-waste production process thereof. A crudely-purified plant urease solution includes a large amount of irrelevant proteins, which seriously affects the treatment effect of the soil solidification agent, makes it impossible to achieve an expected construction purpose, and also causes serious waste and environmental pollution. In the present invention, a common plant urease extraction method on the market is optimized to significantly reduce a protein concentration in a plant urease solution, greatly improve the infiltration performance of a plant urease-containing soil solidification agent, and broaden an application range of such a soil solidification agent.

  • Publication number: 20220250408
    Abstract: Provided in the present invention is a diagenetic cementation solution and a method for manufacturing a sand sculpture with the same. The diagenetic cementation solution includes a urease-containing plant powder, urea, calcium salt and a cementation solution, wherein the urease-containing plant powder is dissolved in the cementation solution in a mass ratio of 10:50 to 1:50, a resulting mixture is stirred and left to stand for a period of time, and a supernate is reserved; a mixture of the urea and the calcium salt is dissolved in the supernate in a mass ratio of 1:5 to 1:20. The method for manufacturing a sand sculpture includes: ramming a foundation by means of the diagenetic cementation solution, mounting a form and piling sand, pouring and ramming, and removing the form and carrying out sculpturing.
