Problems solved by technology

Due to the large amount of cement in conventional high-pressure rotary grouting water-stop curtains, high engineering costs, and low reliability of material design, the application of high-pressure rotary grouting water-stop curtains is greatly limited.
[0004] In the existing method of reducing the cement consumption of the high-pressure rotary jetting water-stop curtain, although the usage of cement is reduced, the anti-seepage ability of the water-stop curtain is poor, and the performance of the high-pressure rotary jet water-stop curtain cannot be better utilized. Anti-seepage effect

Abstract

The invention relates to a high-pressure rotary jet water-stop curtain supporting impermeable solidified material and a preparation method and application thereof. It includes the first component, the second component and the third component, the first component is Portland cement, the second component is composed of sintered red mud, fly ash, and nickel slag, and the third component is excitation agent. The first component is 60-80 parts, the dosage of the second component is 20-40 parts, and the dosage of the third component is 3-14% of the total of the first component and the second component. The preparation method is simple and easy to operate, the operation is convenient, the prepared composite curing agent has high early strength, and the strength and fluidity can be adjusted, which not only reduces the cost of the high-pressure rotary jet water-stop curtain, but also realizes the solidification of bulk solids such as red mud and fly ash. The reduction and utilization of waste has good economic and social benefits.

Description

technical field [0001] The invention belongs to the field of road engineering materials, in particular to a high-pressure rotary jet water-stop curtain support impermeable solidified material and a preparation method and application thereof. Background technique [0002] The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and should not necessarily be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. [0003] High-pressure rotary jet water-stop curtain is a vertical anti-seepage technology commonly used in deep foundation pits, underground engineering and water conservancy projects. It mainly uses high-pressure jet technology to punch the soil, drill holes in the foundation and spray cement slurry, The rotating and lifting of the slurry pipe mixes the grouting material with the agitated soil...
