Technical Field

The invention relates to the technical field of building materials, in particular to a roadbed material.

Background

In the construction process of subway construction engineering, a large amount of waste residue soil slurry can be generated. The main components of the mud are clay and water, and simultaneously contain a large amount of sandstone, usually, only a large amount of mud ponds can be built on a construction site, and the waste mud is stored and then is gradually treated. However, construction sites are mostly in urban areas, some sites are also located in luxurious commercial and traffic areas, the existence of the mud pit not only occupies a precious construction site, but also influences the construction progress and the site environment, and the collected mud cannot be stored for a long time.

After the stored slurry is generally washed by water to obtain gravels with economic value, the washed slurry is transferred to a remote place to be dumped and is even illegally discharged in drainage ditches in urban areas, so that a series of environmental problems such as land pollution, pipe network blockage, water and soil loss and the like are caused. The discarded slurry can not be reasonably utilized, and serious resource waste is caused.

Detailed Description

In order to explain technical contents, achieved objects, and effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.

The most key concept of the invention is as follows: the roadbed material takes the slurry as a raw material, the rapid solidification of the slurry is realized through the inorganic cementing material, and a large amount of waste slurry generated in the process of constructing the subway is reasonably utilized.

Referring to fig. 1, a roadbed material comprises the following components by weight percent:

the structural principle of the invention is briefly described as follows: the slurry can be rapidly solidified under the action of the inorganic cementing material, the waterproofing agent is matched with the muck, the water content of the roadbed material can be kept in a proper area, and the fluidity and the adhesiveness of the roadbed material are controlled.

From the above description, the beneficial effects of the present invention are: the roadbed material takes the slurry as a raw material, the rapid solidification of the slurry is realized through the inorganic cementing material, and the roadbed material widely applicable to roadbed paving is prepared by reasonably utilizing a large amount of waste slurry generated during subway construction, so that the roadbed material has high environmental protection value.

Further, the soil stabilizer also comprises 0.02-0.05 wt% of soil stabilizer.

As can be seen from the above description, the soil stabilizer can change the characteristics of the soil surface charges in the slurry, reduce the repulsive force among the soil particles, and improve the adsorption force among the soil particles

Further, the building material also comprises 0-20 wt% of building aggregate.

From the above description, it can be seen that the building aggregate is capable of providing the necessary support within the slurry.

Further, the inorganic cementing material is one or more of cement, gypsum and slag micropowder.

From the above description, it can be seen that the combination of various inorganic cementitious materials enables fine control of the hardness of the roadbed material.

A preparation method of a roadbed material is used for preparing the roadbed material and comprises the following steps:

s1, putting 60-80 wt% of slurry, 5-10 wt% of inorganic cementing material, 0.1-0.2 wt% of waterproofing agent and 10-20 wt% of residue soil into a stirring cylinder for stirring;

s2, spraying 0.02-0.05 wt% of soil curing agent into the stirring cylinder during the stirring process of the step S1 to form a mixture.

Further, step S3 is included after step S2, building aggregate is added to the mixture to form the roadbed material.

Further, the moisture content of the roadbed material is 5-8%.

As can be seen from the above description, maintaining the moisture content at 5-8% facilitates the transportation and transfer of the subgrade material.

Further, the soil stabilizer in step S2 is diluted and sprayed.
