According to the grouting material disclosed by the invention, the technical problem that the existing organic grouting material cannot be grouted once after being mixed with an inorganic grouting material, and the technical problem that the existing grouting material has poor durability, low strength, poor water solubility, low water expansion rate and high toxicity are solved.
Description
Technical field
The present invention relates in a kind of Geotechnical Engineering antiseepage, leak stopping grouting material, and in particular to it is a kind of to be applied to ground
Foundation treatment engineering antiseepage and reinforcing, the sealing of movement joint leak and the environmentally-friendly acrylic ester grouting material and its preparation reinforced
Method and application.
Background technology
In dealing with foundation project seepage controlling with consolidation process, frequently with acrylates grouting material and modified epoxy tree
Fat grouting material carries out antiseepage and consolidation process as grouting material.But organic grouting material price is higher, causes to be constructed into
This height.For this purpose, unit in charge of construction wish by organic grouting material and routine inorganic grouting material for example cement mortar, clay cement grout,
Bentonite cement slurry etc. is mixed and is in the milk, and replaces organic chemistry grouting material to be filled with part inorganic grouting material
Slurry, can be greatly lowered construction material cost, improve the durability of material, simplify construction technology.But current has mechanical irrigation
Pulp material can not be mixed with inorganic grouting material, together carry out chemical grouting, such as acrylates grouting material and cement mortar
When liquid mixes, acrylates grouting material meets the silicate ion in cement, produces rapidly precipitation, loses concrete castability；Polyurethane
Grouting material meets the water in cement mortar, rapid to foam, and loses concrete castability；Modified epoxy grouting material is met in cement mortar
Water, in fact it could happen that situations such as not solidifying.
Meanwhile, the movement joint leak in underground space structure is also current one big difficult point of construction, existing organic injection material
Material can not effectively solving movement joint seepy question.Acrylates grouting material gelling time is difficult to, by temperature, initiation
The factors such as dosage, impurity affect larger, and accurate gelling time is difficult to control to；The solid content of acrylate grout is limited, it is impossible to
More than 40%, cause its gel low intensity, be similar to jelly colloid, after water swelling, gel intensity is very low, highly brittle, easily
Extrude from crack, the grouting to waterproof for not being suitable for movement joint is processed.Polyurethane grouting material is divided into oil-soluble and water-soluble filling
Two kinds of pulp material, the polyurethane grouting material for concrete crack crack are mainly soluble polyurethane grouting material.The material
Material meet Water blown, after foaming into crack micropore in, but foam after foams it is very soft, cause foam Hole compared with
It is many and be interconnected.Engineering practice is proved：Carried out after sealing using polyurethane grouting material, general effective time is that half a year is left
The right side, occurs the situation of leak after half a year again.Therefore, Shenzhen Metro, Guangzhou Underground are it has been specified that polyurethane mustn't be adopted
Grouting material carries out sealing, Anti-seeping technology to distress in concrete.Modified epoxy grouting material be a kind of viscosity it is low, solidification after
The high grouting material of intensity, is widely used in the improvement of various dry concrete diseases.But due to modified epoxy grouting material
It is oiliness, and the interface of the movement joint of leak is flooded profit, water-oil phase is unable to bonding, causes modified epoxy injection material
Expect that the repairing effect to leak movement joint is limited, treatment effect is bad.
