Problems solved by technology

[0002] At present, materials such as water glass, cement slurry, etc. used in the filling construction of water, the back of structures, tunnel roofs, goafs and lava areas in China are relatively expensive.
However, ordinary air bubble mixed light soil is used for filling. Due to the high fluidity of ordinary air bubble mixed light soil, the grout will leak from small cracks during pouring, and it is easy to flow to the non-filling area.
In addition, there will be problems such as dispersion, outflow, and defoaming in the presence of water

Embodiment 1

[0012] Plasticized air bubble mixed light soil, its main components include cement, appropriate amount of water, appropriate amount of air bubbles and plasticizer solution, including 250 kg of cement, 100 kg of water, 300 L of foam, and the amount of plasticizer solution in light soil The weight percent content is 3%. The main components of the plasticizer solution are aluminum chloride, sodium sulfate and water, and the proportion by weight is: 30% of aluminum chloride, 10% of sodium sulfate and 60% of water. After the cement, water, air bubbles and plasticizer solution are mixed evenly, the cavity is filled. The mechanism of action of aluminum chloride: aluminum ion (AL 3+ ) in aqueous solution with {AL(OH 2 ) 6} 3+ It exists in the form of aluminum oxide, and if alkaline agent (cement) is added to it, white colloidal precipitate alumina colloid can be produced instantly. Aluminum chloride can quickly gel air bubbles mixed with light soil, reduce fluidity, and have floc...

Embodiment 2

[0013] Plasticized air bubble mixed light soil, its main components include cement, appropriate amount of water, appropriate amount of air bubbles and plasticizer solution, including 250 kg of cement, 100 kg of water, 300 L of foam, and the amount of plasticizer solution in light soil The weight percent content is 5%. The main components of the plasticizer solution are aluminum chloride, sodium sulfate and water, and the proportion by weight is: 40% of aluminum chloride, 8% of sodium sulfate and 52% of water. Cement, water, air bubbles and plasticizer solution are mixed evenly for cavity filling construction. Aluminum chloride can quickly gel the light soil mixed with air bubbles, reduce fluidity, and have flocculation effect, making it difficult to disperse underwater; sodium sulfate It can improve its early strength and ensure molding.

Embodiment 3

[0015] Plasticized air bubble mixed light soil, its main components include cement, appropriate amount of water, appropriate amount of air bubbles and plasticizer solution, including 250 kg of cement, 100 kg of water, 300 L of foam, and the amount of plasticizer solution in light soil The weight percent content is 6%. The main components of the plasticizer solution are aluminum chloride, sodium sulfate and water, and the proportion by weight is: 50% of aluminum chloride, 5% of sodium sulfate and 45% of water. Cement, water, air bubbles and plasticizer solution are mixed evenly for cavity filling construction. Aluminum chloride can quickly gel the light soil mixed with air bubbles, reduce fluidity, and have flocculation effect, making it difficult to disperse underwater; sodium sulfate It can improve its early strength and ensure molding.

Abstract

The invention discloses plasticizing bubble mixed light soil, which comprises the following main components: cement, a proper amount of water, a proper amount of bubble and plasticizing agent solution, wherein the plasticizing agent solution accounts for 3 to 6 weight percent of the light soil. The plasticizing agent solution is added into the common bubble mixed light soil to make the bubble mixed light soil quickly solidified and reduce the fluidity, and the plasticizing agent solution also has the flocculation function, so the bubble mixed light soil is difficult to disperse underwater; and the plasticizing bubble mixed light soil has the advantages of low fluidity, difficult leakage in the casting process and no dispersion in water, and is suitable for filling holes.

Description

technical field [0001] The invention relates to an air-bubble mixed light soil, in particular to a plasticized air-bubble mixed light soil used for filling cavities in water, backs of structures, tunnel roofs, goafs and lava areas. Background technique [0002] At present, materials such as sodium silicate and cement slurry are relatively expensive in the domestic construction of hollow filling in water, the back of structures, tunnel roofs, goafs, and lava areas. However, ordinary air bubble mixed light soil is used for filling. Due to the high fluidity of ordinary air bubble mixed light soil, grout will leak from small cracks during pouring, and it is easy to flow to non-filling areas. In addition, there will be problems such as dispersion, outflow, and defoaming in the presence of water. Contents of the invention [0003] The object of the present invention is to provide a plasticized air-bubble mixed light soil which has low fluidity, is not easy to leak grout during ...
