Problems solved by technology

[0004] However, when the ready-mixed fluid solidified soil is used in the construction of composite pile foundation, since the foundation pile hole is generally deep and the hole is narrow, it is not convenient to vibrate the fluid mixture slurry. During the maintenance process, the mixing The heavy component in the water slurry is easy to sink, and the light component is easy to float, resulting in uneven solidified soil material, resulting in inconsistent shrinkage, and cracks are likely to occur during the curing process of the pre-mixed fluid solidified soil, which affects the construction quality and endangers product safety. Sex has certain adverse effects

Embodiment 1

[0036] Embodiment 1: A preparation process of composite pile ready-mixed fluid solidified soil slurry, comprising the following steps:

[0037] Preparation of S1 modifier: Weigh 5.5Kg of carboxymethyl cellulose, add 5Kg of ethylene glycol monoallyl ether, 8Kg of polycarboxylate water reducer and 3.5Kg of polyether defoamer, and mix evenly to obtain modified sex agent.

[0038] S2 activator preparation: Weigh 7.5Kg triethanolamine, add 5Kg sodium sulfate, 7Kg calcium sulfoaluminate and 18Kg neutral nano-silica sol (sodium oxide content 0.15%, silicon dioxide content 40%, the rest is water, neutral nano-silica sol The median particle diameter (D50) of the silica sol is 44.3nm), and then 6Kg of 13X zeolite powder was added and mixed evenly to prepare the activator.

[0039]Preparation of S3 liquid solidified soil slurry: sieve the clay with a sieve with a hole diameter of 20 mm, and select clay with a particle size not greater than 20 mm. Screen the fine sand with a sieve with ...

Embodiment 2

[0041] The difference between Example 2 and Example 1 is that the neutral nano-silica sol is not added in Example 2, and the others are consistent with Example 1.

Embodiment 3

[0043] The difference between Example 3 and Example 1 is that Example 3 does not add 13X zeolite powder, and the others are consistent with Example 1.

Abstract

The invention discloses premixed flow-state solidified soil slurry for a composite pile and a preparation method of the premixed flow-state solidified soil slurry, and relates to the technical field of preparation of building materials. The invention discloses premixed flow-state solidified soil slurry for a composite pile. The premixed flow-state solidified soil slurry is mainly prepared from thefollowing solidified soil slurry raw materials in parts by weight: 450-550 parts of clay, 80-120 parts of cement, 260-340 parts of fine sand, 60-100 parts of water and 350-450 parts of coal ash. Thesolidified soil slurry further comprises a modifier, and the modifier comprises the following modifier raw materials in parts by weight: 4-7 parts of carboxymethyl cellulose and 2-8 parts of ethyleneglycol monoallyl ether. The solidified soil slurry raw material further comprises an excitant. The premixed flow-state solidified soil slurry of the composite pile has the advantage of high safety. The preparation method of the premixed flow-state solidified soil slurry for the composite pile comprises the following steps: preparation of the modifier, preparation of the excitant, preparation of the flow-state solidified soil slurry and the like. The preparation method of the premixed flow-state solidified soil slurry for the composite pile has the advantage that the product safety can be improved conveniently.

Description

technical field [0001] The invention relates to the technical field of building material preparation, in particular to a composite pile ready-mixed fluid solidified soil slurry and a preparation method thereof. Background technique [0002] In modern buildings, especially high-rise buildings, in order to improve the safety of the building, it is generally necessary to pour composite pile foundations. The composite pile foundation uses liquid solidified soil slurry as the cementing material, and presses the liquid solidified soil slurry into the hole formed by the long spiral drill to form a pre-mixed fluid solidified soil pile. The pile, the soil between the piles, the cushion layer and the foundation A composite pile foundation is formed, which improves the bearing capacity and safety of the pile foundation. [0003] The application document of application publication number CN107572956A discloses a ready-mixed fluid solidified soil, which is composed of water, soil, compo...
