Mixture stirring and conveying device and construction method

Abstract

The invention discloses a mixture stirring and conveying device and a construction method. The device comprises a stirring machine, a conveying pump, a movable conveying pipe, a moving platform, and atransmission machine for conveying a material to be stirred to the stirring machine. The stirring machine comprises a stirring bin, a stirring system and a power system; the stirring system comprisesa plurality of stirring paddle groups; the stirring paddle groups are uniformly distributed on the periphery of the power system; each stirring paddle group comprises an outer stirring paddle and a plurality of inner stirring paddles; one outer stirring paddle in each two adjacent stirring paddle groups is provided with a side stirring blade clinging to a side wall of the stirring bin, and the bottom part of the other outer stirring paddle in each two adjacent stirring paddle groups is provided with a bottom stirring blade clinging to a bottom wall of the stirring bin, so that the material isstirred more uniformly; and shapes of the outer stirring paddles and the inner stirring paddles correspond to a shape of the side wall of the stirring bin, and the outer stirring paddles and the inner stirring paddles are arranged parallel to the side wall of the stirring bin, so that the material to be stirred can fully contact the outer stirring paddles and the inner stirring paddles, and is stirred more uniformly.

Description

technical field [0001] The invention belongs to the field of civil engineering construction, and in particular relates to a mixing and conveying device and a construction method. Background technique [0002] With the development of engineering technology, the progress of social material civilization, and the improvement of environmental quality standards, the number of underground construction projects in cities is increasing, and the output of foundation pit sludge in construction projects is also increasing rapidly. Through a series of soil material performance studies, we added a certain proportion of cement, fly ash and other admixtures to the foundation pit sludge to improve the water content, compactness and mechanical properties of urban sludge, and met the requirements of urban ultra-deep and super-large The backfill requirements of the foundation pit project reduce the use of mixtures such as sand and gravel; shorten the transportation distance of traditional found...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a mixing and conveying device and a construction method for realizing sufficient and efficient mixing of materials, reducing energy consumption, and solving problems in the prior art that the cohesion of concrete and mortar is lower than that of foundation pit sludge. , high fluidity, such as uneven stirring, it is difficult to meet the requirements for the preparation of fast-hardening materials for foundation pit sludge after large-scale improvement
