Novel pouring device for model test and application method

Abstract

The invention discloses a novel pouring device for a model test and an application method. The novel pouring device comprises a slurry stirring device, wherein the slurry stirring device is connected with a pouring pressure device through slurry feeding pipes, the pouring pressure device is connected with a slurry feeding pipe conversion device through the slurry feeding pipes, and the slurry feeding pipe conversion device is connected with pouring pipes through the slurry feeding pipes. The novel pouring device provided by the invention has the advantages that the device is simple, the operation is convenient, the detachability is strong, and the transportation is convenient; the pouring pressure device is provided with marks, the pouring quantity is controlled, the pressurization can be easily and manually carried out and is free from limitation of energy such as power supply; the slurry feeding pipe conversion device can realize simultaneous pouring by using multiple pouring pipes, the number of the starch feeding pipes of pouring is simultaneously controlled, and the pouring efficiency is notably improved; and once uniform pouring can be realized through the bottoms of the pouring pipes and pouring holes in pipe walls, and the pouring effect is notable.

Description

technical field [0001] The invention relates to a novel grouting device and a using method, in particular to a novel grouting device and a using method for model tests. Background technique [0002] The grouting technology is to inject some grout that can be well consolidated with the rock and soil into the pores and cracks of the rock and soil by hydraulic, pneumatic or electrochemical methods, so that the rock and soil become a high-strength, resistant A new structure with good permeability and high stability can achieve the purpose of improving the physical and mechanical properties of rock and soil. [0003] In recent years, my country's underground engineering has developed rapidly, especially the construction of urban subways. The uneven settlement hazards of surrounding buildings, roads, pipelines and existing lines caused by subway construction are very serious, and grouting technology also plays a significant role in settlement control. But on the other hand, grou...

AI Technical Summary

Problems solved by technology

However, model experimental grouting devices are relatively rare. The experimental devices developed by predecessors are too complicated, and there are major problems in experimental operation and experimental efficiency, which are increasingly unable to meet the development of grouting engineering.
