Embodiment 1

[0032] combine figure 1 and figure 2 , a mobile modified engineering soil mixing device of the present embodiment is mainly composed of a carrying trailer 19, a stirring mechanism and a driving mechanism, and the stirring mechanism and the driving mechanism are both arranged on the carrying trailer 19. A balance support 21 is arranged at the front, middle and rear positions of the transport trailer 19, and the balance support 21 is symmetrically arranged on both sides of the transport trailer 19. During the movement of the transport trailer 19 through the wheels 20, the balance support 21 is in a contracted state. During work, The balance support 21 is supported on the construction ground, making it more stable and not easy to shake during work. One end of the carrying trailer 19 is provided with a supporting hook 22 to facilitate pulling and carrying the carrying trailer 19 .

[0033] The mixing mechanism in this embodiment includes an outer mixing drum 4, an inner mixing ...

Embodiment 2

[0040] A mobile modified engineering soil mixing device of this embodiment has the same basic structure as that of Embodiment 1, the difference being that in this embodiment, the non-continuous spiral stirring blades 6 arranged on the inner wall of the outer mixing drum 4 are arranged in a cross arrangement , the spiral stirring blades 6 between the middle part of the outer mixing drum 4 and the lower end of the outer mixing drum 4 are arranged at equal intervals, and the distance between the spiral stirring blades 6 from the middle part of the outer mixing drum 4 to the upper end of the outer mixing drum 4 gradually becomes smaller, that is, the spiral stirring The arrangement of the blades 6 is finer and has a better pulverizing effect. At the same time, it can increase the friction between the outer mixing drum 4 and the materials, and has a greater lifting force, and accelerates the materials entering the feeding port 11 of the inner mixing drum. The inclination of the set ...

Embodiment 3

[0042] A mobile modified engineering soil stirring device of this embodiment has the same basic structure as that of Embodiment 1, the difference is that in this embodiment, the inner wall of the inner mixing drum 5 is provided with two continuous spiral stirring fins 7 , forming a double-screw conveying structure, which can speed up material conveying.

Abstract

The invention discloses a mixing and stirring method for modified engineering soil and belongs to the field of stirring equipment. A carrying trailer, a stirring mechanism and a drive mechanism are arranged, wherein the stirring mechanism and the drive mechanism are both arranged on the carrying trailer. The stirring mechanism comprises an outer stirring barrel, an inner stirring barrel and a grid wheel type feeding machine. In the stirring process, ingredients for a modifier and the engineering soil are fed from a hopper, the ingredients fall into an outer stirring barrel feeding opening from a feeding pipe after passing through the grid wheel type feeding machine, the ingredients enter the inner stirring barrel to be stirred directly after being stirred in the outer stirring barrel, and the ingredients flow out of an inner stirring barrel discharging opening and become the fully-modified engineering soil. By means of the method, a small amount of the modifier can be uniformly mixed into the engineering soil, the modification effect is improved, raw materials are saved, field use is facilitated, and the project cost and construction cost are lowered.

Description

[0001] The patent application of the present invention is a divisional application with the application number: 2015105013445. The filing date of the original application is: 2015-8-14. The name of the invention is: a mobile modified engineering soil mixing device. technical field [0002] The invention relates to the technical field of stirring equipment, in particular to a mixing and stirring method for modified engineering soil. Background technique [0003] During the construction of highways and railways, the reinforcement of soft ground is often encountered. Generally, engineering soil is used to compact it to form a solid foundation. If clay and sandy soil are encountered, because these soil engineering soils are used as the foundation In the rainy season or when the groundwater level rises, water will swell and the road surface will be destructively affected, resulting in cracking of the road concrete pavement (cement or asphalt) and deformation of the railway rails. ...
