Problems solved by technology

Advantages of wooden sleepers: easy processing, transportation, laying, maintenance and repair, good elasticity, can buffer the dynamic impact of trains, simple connection with rails, good insulation; disadvantages: consume a lot of high-quality wood, high price, easy to corrode and wear , short service life, uneven strength and elasticity
Advantages of concrete sleepers: large longitudinal and lateral resistance, high rigidity, smooth rail bottom deflection, small dynamic slope, high elastic cushion to ensure uniform track elasticity, long service life, reduce maintenance costs, and save wood; Disadvantages: irregularities , the additional power of the track increases, and the requirements for the elasticity of the components under the track are higher
[0008]2. Current status of Yellow River sediment
In the lower reaches of Shandong, Henan and other sandy rivers, the sediment deposition in the middle and lower reaches of the river reduces the flood discharge capacity of the river, and it is necessary to continuously increase the height of the flood control embankment, which greatly increases the cost of the flood control project.

Abstract

The invention relates to a production method for a light sleeper made of a microcrystal material. Resourceful sediment in the yellow river is used as a major raw material, and auxiliary raw materials mainly include calcium stone powder, industrial barium carbonate, industrial soda ash, industrial borax, commercial alumina, zinc oxide, a clarifying agent and the like. The light sleeper made of the microcrystal material has the advantages that the light sleeper has good physical and chemical performance, light weight and high strength and is environment-friendly, a production technology process of the light sleeper is suitable for industrial production lines, the raw materials are rich, cost is low, production efficiency is high, energy is saved, and resource is effectively and comprehensively used.

Description

Technical field: [0001] The light-weight sleeper of microcrystalline material in the present invention is a silicate product, belongs to the products of the silicate industry, and particularly relates to a production method of light-weight sleeper of microcrystalline material. Background technique: [0002] 1. Status of sleepers [0003] Sleepers are load-bearing objects, and are materials used for laying railways, special track running equipment and bearing equipment bedding. Its function: withstand the pressure from all directions of the rail, and spread it elastically on the ballast bed, effectively maintaining the geometric shape of the track, especially the gauge and direction. Requirements for sleepers: have the necessary firmness, elasticity and durability, and can facilitate the fixing of rails, and have the ability to resist longitudinal and lateral displacement. [0004] Sleeper classification: wooden sleepers, reinforced concrete sleepers, steel sleepers, c...
