Problems solved by technology

[0004] However, in the process of mixing the solidified soil, the soil material, curing agent and water are generally mixed at one time and stirred. There are often problems such as insufficient strength of the solidified soil to meet the needs of the project, which in turn affects the construction quality.

Embodiment Construction

[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0024] In this embodiment, in this embodiment, a moist caking material is added to the solidified soil, and the main component of the material is natural dihydrate gypsum with a chemical formula of CaSO4·2H2O. Natural dihydrate gypsum is also called air-hardening inorganic gelling material. This kind of gypsum is lumpy and lumpy, and has cohesiveness. It is directly mixed into the undisturbed soil, and it is not easy to stir and cannot be mixed evenly. And the screw conveyor cannot be used for material transportation. If it is used forcibly, it will stick to the blades and pipelines of the screw conveyor, causing failure.

[0025] Adding gypsum into the solidified soil can shorten the solidification time of the solidified soil, adjust the acidi...

Abstract

The invention provides a solidified soil preparation system. The system comprises an initial material stirring barrel, a curing agent slurry stirring station and an on-site mixing solidified soil stirring station which are connected in sequence. The initial material stirring barrel is used for preparing wet cohesive material slurry which cannot be directly conveyed by a spiral conveyor. The curing agent slurry mixing station is connected with the initial material mixing barrel and is used for mixing and stirring wet adhesive material slurry and a powdery curing agent to form curing agent slurry. The on-site mixing solidified soil stirring station is connected with the curing agent slurry mixing station, and is used for mixing the curing agent slurry with soil to form on-site mixing solidified soil. According to the solidified soil preparation system disclosed by the invention, wet adhesive materials such as gypsum are doped into the solidified soil during preparation, the solidification time of the solidified soil can be adjusted, and the acid-base property of the solidified soil can also be adjusted. By doping slag, the cement consumption is reduced, and the cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a preparation system for solidified soil. Background technique [0002] In the construction of construction projects, subway construction, exploration, pile foundation, drilling, and underground foundation pit drilling and excavation, a large amount of waste soil and slag are produced. This part of the waste soil and slag is a kind of clay, organic and inorganic material additives , a multiphase stable colloidal suspension of dirty oil and drilling cuttings, the composition of which is quite complex. [0003] In our country, it is of far-reaching historical significance to vigorously develop building materials that save energy, save soil, use waste, protect the environment and improve building functions. It is a major measure to achieve sustainable development and a great cause that will be left to future generations. A series of treatments are used as building materia...
