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 jet grouting waterproof curtain support impervious curing material as well as a preparation method and an application thereof. The material comprises a first component, a second component and a 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 an exciting agent. The mixing amount of the first component is 60-80 parts, the mixing amount of the second component is 20-40 parts, and the mixing amount of the third component is 3-14% of the sum of the first component and the second component. The preparation method is simple and easy to implement and convenient to operate, the prepared composite curing agent is high in early strength and adjustable in strength and fluidity, the cost of the high-pressure jet grouting waterproof curtain is reduced, reduction utilization of a large amount of solid waste such as red mud and fly ash is achieved, and good economic and social benefits are achieved.

Description

technical field [0001] The invention belongs to the field of road engineering materials, and in particular relates to a high-pressure rotary spraying water-stop curtain support anti-seepage solidification material and a preparation method and application thereof. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] High-pressure rotary spraying 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 rotation and lifting of the grout pipe makes the grouting materi...
