Method of the present invention is applicable to the sclerosis soil course in the civil engineering.Its scope of application is mud, the loess except that colloid earth (more than the 0.008mm-0.001mm), (road performance, plane dig, seize by force greatly the civil engineering of the mixed soil of earth and sandy soil one class, the water route, farming soil, military etc.), particularly major part is general loess in the soil of China, and adding most of becomes composite soil through weathering or acidifying.Therefore method of the present invention is just utilized these characteristics, spills two kinds of solution on the composite soil of bottom, i.e. first solution and inorganic sclerosis by the organic polymer resin composition promotes the composition that second solution of composition mixes.At first they are mixed up, use bulldozer then, rivet bucker pressurizes and makes this soil can reach the desired hardness of civil engineering.
The material of soil hardening mainly is made of in the past inorganic substances, thereby which floor soil will be rolled up, will phenomenon occur subsideing by some soil like this.Add remote conveying inorganic substances and also can increase the weight of economically burden.
The intensity of road is 10kg/cm at present
2More than just up to specification.
In the material of the soil that uses in handling civil engineering, the organic polymer material is to promote sclerosis and waterproof, also makes simultaneously to produce between the particle of soil and the particle to reinforce reaction, to making the solid and water proofing property raising of the knot of strengthening hardness.
Inorganic substances (rapid hardening, gel and special dry thing) and organic polymer material are being mixed and forming in the process of new organic polymer material.If the use vinyl latex, inundation rate height then, a little less than the water-fast power, if use urea resin solution, though good economy performance, crack performance is serious, and aggressivity is increased.
In addition, also once inorganic matters such as the calcium sulphate powders of 3%-6% or lime are used for road construction, but did not give employing because of insufficient strength.
Method of the present invention has overcome above shortcoming, in construction, is embedded in bottom equably in order to make on-the-spot assorted stone, and is even with the sanding machine mill earlier, and soil is crushed.Then organic polymer resin composition and inorganic sclerosis are promoted that composition mixes by a certain percentage, spray equably, press several times with rivet bucker again with sprayer.Just mutual mixing of moisture content and chemical substance and normal temperature are dry down in the soil like this.Utilize the complex engineering of earth, sandstone, salt, lime, rubble, cement etc. before so just having saved, and finish rapid hardening and the high strength sclerosis method that provides novel at short notice for engineering.
Used organic polymer resin composition is based on a certain proportion of gluey vinyl acetate resin and gluey acrylic acid resin composition in the method for the present invention, also have with the phenol of 1: 1.5 ratio and formaldehyde and get system, wherein free phenol content is 6-7%, water content is 40-50%, the pH value is 8-12, phenolic resins is as reinforcement, and handle is by handling the acrylamide agent as a supplement that acrylonitrile gets.
It is cold that these materials are carried out speed, and the resulting material of fast heat treatment is to have certain flexible jelly composition.
Thereby when the used material of method of the present invention and the particle in the soil are had an effect, can be strong in conjunction with and preventing of making that air intercepts, shrinks, hardness is strengthened and performance such as water resistance is strengthened.Simultaneously, the adhesion between the inorganic substances of interpolation is strengthened.In addition, the main body in the organic polymer resin composition that uses in the method for the present invention, i.e. acrylic resin and vinyl acetate resin, ratio be 35: 30, the shared ratio of this main body is 65%; Water soluble phenol resin accounts for 15%, and acrylamide accounts for 20%.The used material of method of the present invention is cold through speed, and the stoste of speed heat is used after can it being diluted according to actual conditions in use again.
Second solution that method of the present invention is used, promptly inorganic sclerosis promotes composition, a sodium phosphate trimer, the sodium silicofluoride of referring to, sodium sulphate, NaOH, calcium stearate, magnesium chlorides etc. were in 1: 1: 2: the composition that 1: 3: 2 ratio is mixed.This composition can make raisings such as rapid hardening, water proofing property.
These materials can make drying, gel, rapid hardening, dispersiveness obtain performance, also add strong hardness simultaneously.
By usage degree method of the present invention is described once below:
The first road program (be to analyze soil, mensuration pH value, and handle the set-up procedure of two kinds of chemical combination materials with machine).It is dark earlier soil to be dug 20cm, again soil block and soil is done even.Desirable water content is below 10%.Will adjusting if surpassed remainder.
First solution (organic polymer resin composition) will be contained in the mixer, will stir along with the pressure of the machine that spraying machine and mixer are started the simultaneously speed with 60-100RPM simultaneously.
The spray method of second solution too
The 2nd program (pressurization program)
After being over, first engineering to soil be pressed several times with rivet bucker.At this moment two kinds of solution will be mixed in the soil equably, and usefulness such as gel, waterproof, drying, rapid hardening are occurred.
This processing method, the complicated procedures of forming before having omitted, it is economical that expense is obtained, and project speed is accelerated.
Simultaneously two kinds of compositions combine with moisture content in the soil, make and subside the phenomenon minimizing.
In addition, of the present invention organic polymer resin composition and inorganic sclerosis are promoted the method that composition mixes simultaneously, solved the difficult problem that construction material is bought.Rapid hardening, sclerosis, gel etc. are carried out simultaneously and obtained economically benefit.
The method of invention is described with the construction object below
Example 1, mold
The sieve top sieve of 5mm one time, it is even to be with water content that 8% loess is that material spills organic polymer resin composition 325g then, promotes inorganic sclerosis composition 305g to spill even again general loess 5000g.Colloidization begins after stirring the 5-10 branch.(press among the 20cm * 10cm), pressure will be added to 4.5kg to drop it off the soft machine of building test usefulness again.Through 20 times, (90-100kg/cm
