Description

TECHNICAL FIELD

[0001] The utility model relates to the field of rock and soil reinforcement, especially to a basalt fiber preparation device of alkali erosion. BACKGROUND

[0002] As a supporting means, grouting is very important for the safety and quality of underground construction during the construction process of underground engineering. Geopolymer mortar, as a kind of grouting material, can reinforce deep fractured rock mass, but it has the shortcomings of low toughness and poor ductility. Existing research shows that the "fiber-geopolymer mortar composite material" formed by adding basalt fiber can significantly improve the tensile and shear strength of geopolymer mortar and improve its toughness. During the drawing process of basalt fiber, due to the effect of surface tension, the high-temperature molten basalt will quickly shrink, resulting in that the produced basalt fiber is usually smooth and cylindrical. In the actual application process, it is difficult to tightly combine with the composite material, thereby leading to that the reinforcing effect on the composite material is not obvious. Therefore, it is necessary to modify the surface of basalt fiber, increase its surface activity, and improve the bonding force of the interface with the composite material.

[0003] The alkali erosion modification method is one of the more common methods. Alkaline solution can react with oxides in basalt fiber to form grooves on the surface, showing an anchoring effect in the interface of the composite material. Therefore, alkali-eroded basalt fiber can significantly improve the bonding force of the interface with the composite material. Existing utility model patents, such as patent number ZL202321384903.5, patent name Basalt fiber drying box; and patent number ZL202223248389.0, patent name Drying and curing oven for basalt fiber composite material production, can dry basalt fiber, greatly improving the efficiency of drying basalt fiber, but the function is single. When preparing alkali-eroded basalt fiber, manual operations such as drying, alkali treatment, washing, filtering, and airing of basalt fiber are required, which is complicated, time-consuming, labor-intensive, and low in efficiency; manual operation of dangerous chemicals such as sodium hydroxide increases the safety risk; in an unsealed space, changes in environmental conditions such as temperature and humidity may cause differences in the quality of the fiber treated each time, and the consistency and reliability of the fiber cannot be guaranteed.

[0004] The composite material formed by adding alkali-eroded basalt fiber in geopolymer mortar as a kind of green grouting material can reinforce deep fractured rock mass. However, there is currently a lack of a basalt fiber preparation device for alkali erosion, which can more efficiently, conveniently, and safely prepare alkali-eroded basalt fiber that meets the requirements, so that the consistency and reliability of the fiber are guaranteed.
