Embodiment 1

[0035] The wet thiourea waste residue was dried and dehydrated at 105°C, and ground to 200 mesh to obtain dry powder of thiourea waste residue for future use.

Embodiment 2

[0037] The sandy low liquid limit silt is solidified with the solidifying agent of the present invention.

[0038] The material ratio is shown in Table 2.1:

[0039] Table 2.1 Composition of solidifying agent and solidified soil weight ratio

[0040]

[0041] Specific curing steps:

[0042] A Weigh the dried silt, thiourea waste residue dry powder, and fly ash respectively according to the weight ratio, place them in a mixing pot, and fully stir them with an agitator;

[0043] B Weigh the water according to the weight ratio, add it into the well-mixed silt mixture, and fully stir it with a stirrer;

[0044] C Weigh the anionic emulsified asphalt according to the weight ratio, add it into the silt mixture, and fully mix it with a stirrer;

[0045] D Put the well-mixed silt mixture into the mold, form the test piece according to the compaction degree of 95%, and bag it at room temperature for 7 days.

[0046] The unconfined compressive strength test was carried out on the...

Embodiment 3

[0050] The low liquid limit silt is solidified with the solidifying agent of the present invention.

[0051] The material ratio is shown in Table 3.1:

[0052] Table 3.1 Composition of curing agent and curing soil

[0053]

[0054] The specific curing steps are the same as in Example 2. The experimental results are shown in Table 3.2.

[0055] Table 3.2 Summary of test results of compression test

[0056]

[0057] As can be seen from the test results shown in Tables 2.2 and 3.2, the soil curing agent of the present invention can significantly increase the curing strength of the soil. Through the test of unconfined compressive strength, the strength is suitable for the base and subbase of various roads. Standard, and after soaking the solidified soil specimen, the strength is still high, and it has good water stability.

Abstract

The invention discloses a soil composite curing agent and a soil curing method, and belongs to the field of road engineering. The curing agent is mainly prepared by mixing thiourea waste residue dry powder, fly ash and emulsified asphalt according to a certain ratio. Compared with the prior art, the curing agent has the advantages that thiourea waste residues, fly ash and emulsified asphalt are combined for composite curing of soil, a cured soil body with good strength and high water resistance can be formed, the technical requirement for soil curing in the field of road engineering is met, and the curing agent has good application and popularization value.

Description

technical field [0001] The invention relates to the field of road engineering, and specifically provides a soil composite curing agent and a soil curing method. Background technique [0002] In existing engineering applications, cement, lime, fly ash and other materials are often used to solidify the soil, so as to increase the strength, cohesive force and stability of the soil to meet the needs of the project. However, with the continuous development of road construction, the consumption of building materials and project cost are gradually increasing. If the soil with wide sources, low price, and convenient use is used directly as engineering materials, it can not only reduce the engineering cost and meet the requirements of engineering economy, but also reduce the mining of mineral raw materials and protect the ecological environment. [0003] Thiourea is an important chemical raw material. The thiourea production plant produces a large amount of wet waste residue every y...
