preparation example Construction

[0028] Correspondingly, the embodiment of the present invention provides a preparation method of fluidized solidified soil based on granite dregs, including the following steps:

[0029] S01, weighing raw materials according to the formula: 420-500 parts by weight of granite dregs, 130-160 parts by weight of cement, 20-60 parts by weight of fly ash, and 550-650 parts by weight of water;

[0030] S02, mixing and stirring the cement, the fly ash and the water to obtain a solidified slurry;

[0031] S03, mixing the granite dregs with the solidified slurry to obtain the fluidized solidified soil;

[0032] Wherein, the particle size of the granite muck is below 30mm.

[0033] The preparation method of the fluidized solidified soil provided by the invention mixes cement, fly ash, water and granite slag in specific proportions by weight, and is easy to operate and high in engineering applicability.

[0034] Specifically, in step S01, the particle size of the granite dregs is below ...

Embodiment 1

[0053] In this example, a fluidized solidified soil is prepared, including: 140 parts by weight of cement, 20 parts by weight of fly ash, 600 parts by weight of water, 450 parts by weight of weathered granite slag, 5 parts by weight of water reducing agent, and 15 parts by weight of early strength agent. parts by weight; wherein, the particle size of the granite dregs is below 30mm.

[0054] During preparation, comprise the following steps:

[0055] S11, weighing raw materials according to the formula;

[0056] S12. Put the cement, the fly ash and the water in a forced mixer, and stir at a speed of 200rpm for 1min to mix and stir, so that each component is fully mixed and uniform, and a solidified slurry is obtained;

[0057] S13. Put the granite slag and the solidified slurry in a forced mixer, and stir at a speed of 350 rpm for 2 minutes for mixing, so that all components are fully mixed evenly, and the fluidized solidified soil is obtained;

[0058] S14. Add 5 parts by we...

Abstract

The invention belongs to the technical field of civil engineering, and particularly relates to flow-solidified soil based on granite muck and a preparation method of the flow-solidified soil. The flow-solidified soil based on granite muck provided by the invention comprises cement, coal ash, water and the granite muck. Based on 130-160 parts by weight of the cement, the weight parts of the coal ash, the water and the granite muck concrete are 20-60 parts, 550-650 parts and 420-500 parts, respectively, wherein the particle size of the granite muck is 30 mm or below. Under the synergistic effectof the cement, the coal ash, the water and the granite muck in a specific weight part ratio, the prepared flow-solidified soil has good fluidity, can automatically flow to fill narrow spaces such ascracks and pointing seams, can meet the requirement for strength required by backfilling without manual compaction after backfilling construction, is high in filling efficiency, can simplify the process of backfilling construction, improves construction efficiency and is high in engineering applicability.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to fluidized solidified soil based on granite dregs and a preparation method thereof. Background technique [0002] With the continuous development of urbanization in our country, the above-ground space is gradually saturated, and more and more underground space has been developed, such as the construction of foundations, underground transportation pipelines, underground shopping malls, and underground pipelines. The construction of underground structures is usually carried out by open excavation. After the construction is completed, the foundation pit needs to be backfilled. Rolling is carried out many times, and the amount of work is huge. However, even with repeated rolling, there are still construction sites where the backfill area is not easy to be compacted, such as water storage pipes, gas pipelines, wires, and cables buried under urban roads. The fill...
