Embodiment Construction

[0017] The present invention will be further described in conjunction with the accompanying drawings of the above-mentioned embodiments.

[0018] As shown in the figure, in the red mud rapid solidification dam building method described in the present invention, sub-dams 1, 4 and dam body 2 are piled up. During the dam-building process, the sub-dams are wrapped with plastic film 5 layer by layer from bottom to top to form sub-dams. Wrapping layer, the bottom edge of plastic film 5 is pressed below the sub-dam layer, and the top of plastic film 5 is pressed to the inboard of sub-dam from the outside, the top of sub-dam, and there are two sub-dam bodies 1, 1 and 2 in the dam body 2. The reinforced steel mesh 3 on 4 has a flange extending to the outside of the sub-dam, and the reinforced steel mesh 3 is bent downward between the two sub-dams 1 and 4.

[0019] In the red mud sub-dam construction process, gypsum or limestone solidifying agent of 3-5% by weight of the red mud is adde...

Abstract

The present invention relates to a damming method by utilizing quick solidification of red-mud, and is a damming technique by adopting red-mud sintering process. Said method includes the following steps: embanking subdam and dam body, using plastic film to wrap subdam to form subdam wrapped layer; in the course of embanking red-mud subdam adding solidifying agent whose added quantity is 3-5% of red-mud weight into the red-mud, and in the course of embanking dam body adding permeation setting accelerator whose added quantity is 0.01%-1% of red-mud weight; in the dam body interior erecting reinforced steel nets on two subdam bodies.

Description

technical field [0001] The invention relates to a red mud rapid solidification dam building method, which is a dam building technology of sintering red mud. Background technique [0002] The basic starting point of the sintering red mud accumulation dam is to use the good coagulation characteristics of red mud to form cement stone with a compressive strength of 1-2 MPa or more within a certain period of time. And this kind of condensing time is relatively long, about 1 year. According to the current discharge volume, dams have to be built every 2-3 months. In the lower case, it has to bear the pressure of the upper part and the slurry in the reservoir, and it is easy to collapse the dam. Contents of the invention [0003] The object of the present invention is to provide a red mud rapid solidification dam construction method, which has high dam construction speed, high strength and good quality, and meets the requirements of rapid dam construction. [0004] The red mud r...
