Bionic stirring machine for injection grout, hybrid power bionic stirring system and slurrying method of hybrid power bionic stirring system

Abstract

The invention discloses a bionic stirring machine for injection grout, a hybrid power bionic stirring system and a slurrying method of the hybrid power bionic stirring system. The bionic stirring machine for injection grout comprises a stirring tank with a feed inlet and a slurry discharge pipe. The bottom face of the stirring tank is an inclined face which is inclined towards the slurry discharge pipe. The upper end of the stirring tank is fixedly provided with a power portion through a supporting frame. The power output end of the power portion is connected with a stirring shaft in the stirring tank. A stirring paddle is vertically or obliquely arranged on the stirring shaft. When the stirring paddle is obliquely arranged on the stirring shaft, the inclination direction of the stirring paddle is opposite to the rotation direction of the stirring shaft. The inner surface of the stirring tank, the inner surface of the feed inlet, the inner surface of the slurry discharge pipe and the stirring paddle are each provided with a plurality of bionic non-smooth units. The superficial area of faces, making contact with the bionic non-smooth units, of the stirring tank, the feed inlet and the slurry discharge pipe is 20-50% of the superficial area of the inner surfaces of the components, and the superficial area of the faces, making contact with the stirring paddle, of all the bionic non-smooth units on the stirring paddle is 20-60% of the superficial area of all surfaces of the stirring paddle.

Description

technical field [0001] The invention relates to a machine tool used in the grouting field, in particular to a bionic mixer for grouting, a hybrid bionic mixing system and a slurrying method thereof. Background technique [0002] Grouting (Injection Grout), also known as grouting (Grouting), is a grout with coagulation ability prepared from certain specific materials in a certain proportion, and is sent to Pour into the cracks, pores or caves in the formation (rock and soil), and make it diffuse, gel or solidify, so as to achieve the purpose of strengthening the formation or preventing seepage and plugging; mainly including static pressure grouting (Static Pressure Grouting) And high pressure jet grouting (High Pressure Jet Grouting) and other types. At present, grouting technology has been widely used in rock and soil reinforcement and anti-seepage in water conservancy and hydropower, transportation, construction, mining and other projects, as well as slope protection, sand...

AI Technical Summary

Problems solved by technology

[0006] When carrying out grouting operations, especially in the field, due to the relatively harsh construction conditions, it is sometimes impossible to connect to municipal power, which leads to relatively power consumption problems Difficult to solve, the usual way is to use diesel / gasoline generators to generate power independently. On the one hand, it needs to consume a lot of fossil fuels such as diesel / gasoline, which leads to higher cost of grouting operations. On the other hand, diesel / gasoline is emitted as fossil fuels after combustion To a certain extent, the pollutants released will also have adverse effects on the environment and ecology.

In addition, the existing traditional mixing and pulping operation basically involves pouring cement powder (ash), water and admixtures into the mixing tank manually from the same inlet. Due to improper operation and other reasons, the slurry material is easily partially dropped and not added to the mixing tank, which will make it difficult to achieve quantitative control of the amount of slurry material added, resulting in the performance of the slurry prepared by mixing with the mixer at the grouting site. The performance of the slurry prepared in the room is inconsistent, that is, the performance of the slurry prepared by stirring the mixer on site cannot meet the expected requirements
