Freezing Method Sinking Deep Study On New Materials And Construction Technology Of Freezing Hole Filling

Research topic of this thesis:Since the freeze thaw holes can easily form a water guide channel secretion, the researchers use to configure certain mine brine water-cement ratio and the proportion of grout sealing fill. Require the slurry has the following characteristics:resistance, the requirements of specific gravity, the strength.The results show that:the study found that with mine brine slurry configured to meet the requirements for frost resistance. Using different sets of water-cement ratio of cement slurry comparative experiments, we found water-cement ratio, the higher the proportion of the higher grout, grout cement ratio, the higher the corresponding strength but lower. Through model experiment, found that when the proportion of 1.6-1.7 grout, its construction best. In addition, through the study of the initial setting time and final setting time was found in the water-cement ratio of between 0.7-0.8 grout the best and most suitable for use as sealing filler material.Through research experiments and model experiments, we found the best water-cement ratio of ore slurry with brine configuration. Finally, field tria Is should be carried out. Study freezing sinking deep freeze hole fill the new material will continue so in the future construction practices and scientific process, but also to study new materials require new materials to better meet the needs of the actual construction, better ensure that the actual quality of construction. And also in the field has expanded more features, such as energy saving, corrosion resistance, etc., in order to achieve unity of performance and environmental features.
