Technology and device for preparing multi-solid phase modified clay paste slurry

Abstract

The invention provides a technology and a device for preparing a multi-solid phase modified clay paste slurry, and relates to the technical fields of mine grouting, and curtain grouting and water plugging of mined mines. The technology is characterized in that clay, water, a solid phase structure agent, an accelerator, a solid phase thickener and a solid phase inert natural plant reinforcement agent are stirred to prepare the paste slurry. The device used by the preparation technology comprises a clay-based slurry base station and a mobile platform, the clay-based slurry base station is provided with a transfer pump, and the transfer pump of the clay-based slurry base station pumps the qualified clay-based slurry into a stirring bin through a base slurry conveying pipeline. The paste slurry has the characteristics of high consistency, low flow rate, rapidness in setting, strong erosion resistance, low water discharging rate, excellent plugging effect on flowing water having a large flow rate, a high runoff speed and a wide water passage, obvious wall hanging effect, stable slurry performances, and good economical and environmentally-friendly properties; and the slurry preparation technology has the advantages of easiness in implementation, high efficiency, small occupied area of the device, high efficiency, and generation of large economic and environmental benefits.

Description

technical field [0001] The invention relates to the technical field of grouting in mines and curtain grouting in mined mines, and more specifically to a preparation process and equipment for multi-solid-phase modified clay slurry. Background technique [0002] Curtain grouting technology is one of the main technical means of mine water disaster prevention and control. As a water plugging technical solution with little impact on the water environment, long-lasting treatment effects, and zero operating costs in the later stage, the nature of the grouting slurry has undoubtedly become a key factor restricting its popularization and application. The construction period of the project and the groundwater environment have a significant impact. The supporting pulping process, equipment and its layout, pulping capacity and the quality of the prepared slurry are important guarantees for the smooth progress of grouting construction. Existing grouting grouts, especially cement clay p...
