Cement soil preparation system suitable for different fluidities and soil bodies

Abstract

A cement soil preparation system suitable for different fluidities and soil bodies includes a soil material sieve separator, a soil material measuring bin, a slurry stirring station, a cement bin, a cement measuring bin, a cement slurry stirring station and a slurry storage tank; the soil material sieve separator is used for sieving a soil material, and the sieved soil material is transported to the soil material measuring bin through a conveying belt 19; the soil material measuring bin is used for weighing a certain amount of soil material according to the set weight, and the weighed soil material is transported to the slurry stirring station through a conveying belt conveyor 3; the slurry stirring station is used for stirring the soil material and water according to the set fluidity, theslurry after stirring is transported into the slurry storage tank; the cement bin is used for storing cement, and a discharge port of the cement bin is connected to an inlet of the cement measuring bin by an air compressor; the cement measuring bin is used for weighing a certain amount of cement according to the set weight, the weighed cement is transported to the cement slurry stirring station through a delivery pipe 22; the cement slurry stirring station is used for stirring the cement and other material flows according to the set fluidity, and the slurry after stirring is transported intothe slurry storage tank; a discharge port of the slurry storage tank is connected with a grouting pipe.

Description

technical field [0001] The invention belongs to the field of construction machinery and equipment, and in particular relates to a system for preparing cement soil (cement composite soil) and a construction method for pouring cement soil in pile holes during pile planting. Background technique [0002] So far, cement-soil preparation equipment is only aimed at cement-soil with a single fluidity and mix ratio. [0003] Chinese patent 200920085149.9 discloses a mobile cement-soil automatic mixing station, which completes the metering, mixing, storage and grouting of cement-soil by setting raw material bins, mixing tanks, slurry storage tanks, delivery pumps and electrical control systems. Its main disadvantages Have: [0004] (1) The principle of the mobile cement-soil automatic mixing plant is to add cement to the mud and mix and stir to make cement-soil. The order of adding such materials can easily lead to uneven mixing of cement-soil and too long mixing time; [0005] (2)...

AI Technical Summary

Problems solved by technology

[0004] (1) The principle of the mobile cement-soil automatic mixing plant is to add cement to the mud and mix and stir to make cement-soil. The order of adding such materials can easily lead to uneven mixing of cement-soil and too long mixing time;

[0005] (2) It is only suitable for cement soil mixed with cement and mud, not suitable for the preparation of high fluidity cement soil and high fluidity cement composite soil (the characteristic of cement composite soil is that mineral powder, silica cementitious materials such as ash and fly ash);

[0006] (3) It is impossible to observe the working performance of cement soil from time to time, which is not conducive to adjusting the mix ratio in time to adapt to different construction conditions;

[0007] (4) It is not suitable for all kinds of soil containing soft stones, soil clods and other large particles of foreign matter, otherwise, it is easy to block the slurry storage tank, delivery pump and hinder the normal operation of the mixing tank blades. It is extremely difficult to clean and maintain, and even affect the duration;

[0008] (5) The preparation of mud in the traditional cement-soil preparation process requires an independent mud pool, which occupies a large area and does not meet the requirements of civilized construction. This patent does not propose a feasible solution for the storage, screening and transportation of soil materials in the mud preparation process. Solution
