sixthly, measuring the water content: a soil moisture meter may be employed, or a conventional simple measuring method may be used: and (3) putting soil into the hands to make a fist, forming soil balls, loosening the hands, preventing the soil balls from scattering, and allowing the soil balls to fall freely to the ground and scatter, wherein the moisture content is about 15%.
Construction process
The specific construction process comprises the following steps:
(1) construction section measurement determination
Measuring by a total station or a corresponding measuring instrument according to a coordinate method, and releasing the side lines of the roadbed according to the design width of the roadbed, wherein the side lines on two sides are preferably 20-40 cm wide respectively when the side lines of the roadbed are released in order to ensure the effective compactness of the roadbed and the stability of the side slope. And then a measurement technician accurately discharges a leveling line, determines the elevation of the longitudinal and transverse sections, marks the elevation on the side drill rod according to the designed elevation, and considers the loose coefficient when the elevation control of the leveling is carried out.
(2) Leveling prepared soil
Loosening soil according to the amount of earth needed in the construction stage, and roughly leveling according to the measured height and width, wherein a manual bulldozer is generally adopted as a leveling method. Large-grained soil is screened in advance for later use.
(3) Spreading the gelled material, mixing (dry mixing)
The high-molecular ecological soil polymeric calcium powder is uniformly spread in the divided squares according to the matching proportion, the surface of the grid is free from blank positions, and the plane is required to be smooth. In the material spreading process, the oversized particles and other impurities are removed. The dry mixing is generally carried out by adopting a high-horsepower tractor with a rotary cultivator for engineering (hereinafter referred to as a rotary cultivator for short) for mixing once (or a road mixer for mixing); small area can be mixed manually.
(4) Spraying curing agent and wet mixing
And (4) taking a representative point to test the water content, and accurately calculating the total water supplement amount required by the operation section. Spraying the soil curing agent twice, spraying 40-45% of the soil curing agent for the first time, mechanically blending for no less than two times, spraying 40-45% of the soil curing agent for two times until the blending color is consistent, and spraying the sealing layer after rolling and forming the rest 10-20% of water.
(5) Spreading the polymerization agent and mixing

The plane is strived to be flat. In the material spreading process, the oversized particles and other impurities are removed. The dry mixing is generally carried out by adopting a high-horsepower tractor with a rotary cultivator for engineering (hereinafter referred to as rotary cultivator for short) for mixing once (or mixing by a road mixer); small area can be mixed manually.
(6) Initial pressing, leveling and rolling of solidified ground
After the mixture is uniformly mixed, a bulldozer is used for preliminary pressure discharge immediately, and a grader is used for shaping. In the leveling process, the newly-mixed mixture is applied to the local low-lying part for compensation and leveling, and thin layer compensation on a smooth plane is forbidden during leveling.
(7) Health preserving and traffic control
And finishing the rolling of each section of the polymer soil layer, spraying the final 10-20% diluted soil polymer solution, immediately interrupting the traffic after the compaction degree is checked to be qualified, starting covering and maintaining, keeping the pavement moist, and maintaining the maintenance time for at least 7 days.
After shaping, compacting at the optimum water content, and making a corresponding rolling scheme according to the difference of road width and road roller wheel track. Usually, 18T-22T vibratory rollers are used to perform compaction operations on the solidified soil layer after the soil layer is subjected to static pressure. For the area inconvenient to get on the road roller, the impact rammer can be adopted, the layers are tamped layer by layer, and the thickness of one layer is preferably 10 cm.
And (4) spraying water and diluted polymerization liquid for curing, and covering for curing.
In the invention: improving the compressive strength: the polymer ecological soil polymerization technology can improve the compactness and flexibility of soil. After compaction and maintenance, the compressive strength of the material can be improved by more than 1-3 times compared with the traditional material with the same amount, so that the soil can be treated into a solid roadbed in situ, and other inorganic waste residue materials can be added to improve the synergistic effect, so that the compressive strength can be greatly improved, and the economic conversion of other inorganic wastes can be enhanced.
Improving the water stability: after the macromolecular ecological soil polymerization liquid is added for solidification, the soil compactness is increased, and capillaries are gradually closed and blocked. The soil hydrophilic ability is greatly reduced, and the hydrophobicity is greatly improved. The soil particles are bridged and the crystals grow and are connected, so that the surface of the soil is permanently solidified, the physical and chemical properties are completely changed, and the corresponding water stability is greatly improved. The practice of the built roadbed in the equatorial region after dry and rainy seasons shows that the roadbed still keeps very strong strength after repeated long-term soaking, drought and other rounds, and the excellent water resistance of the roadbed is fully demonstrated.
The freezing stability is improved: the fundamental point of improving the frost resistance is to improve the water stability and water absorbability, and because the polymerization technology has very low water absorption and good water stability, the influence of the frozen water on the polymerization technology is very small. Therefore, the freeze-thaw resistance is excellent. The absolute value of the temperature shrinkage coefficient of the solidified soil is much smaller than that of the conventional lime soil, lime soil and the like under the low-temperature (below 0 ℃).
The comprehensive quality of the road is improved: through a large number of indoor experiments and long-term construction experience verification, the strength, compactness, resilience modulus, deflection value, CBR (load ratio), shear strength and the like of the solidified soil all reach and exceed the acceptance standard of roadbed materials, so that the comprehensive quality of roads is greatly improved, and the service life of the roads is prolonged;
the raw materials are locally used, the comprehensive utilization is realized, all soil and inorganic materials on the site can be used for filling, and the traditional industrial waste residue can be comprehensively reused. Replaces the traditional pavement base material, greatly reduces the road building cost, and reduces the cost by 20 to 50 percent compared with the traditional pavement base.
And (3) economic benefit analysis: local materials are obtained: the construction of taking earth on the roadbed directly on site does not need to use a transport vehicle to transport sand, stone, water and other materials for a long distance, replaces the traditional road building material, saves material cost, a large amount of transport cost and labor cost, and can reduce the cost by about 30-40% compared with the traditional road building material and process. The utilization rate of equipment and vehicles is greatly reduced, a large amount of investment is saved in the aspect of equipment investment, and the original road building tool is not required to be added with new equipment, so that the road building tool is particularly suitable for areas with high transportation cost and high vehicle cost, and the whole cost is greatly reduced if the expenses of land acquisition, soil excavation, transportation and the like are considered.
The dosage is extremely low: the usage amount of the polymer ecological soil polymerization solution is ten thousandth, and the low addition amount can achieve very good road compression resistance, water resistance and frost resistance effects, and the benefit is very obvious. The addition type of the cementing material is determined according to the grade requirement and the soil condition of the road, and the strength of the cementing material can be greatly increased after the cementing material is matched with a proper cementing material for use.
The water stability is good: the problem of permeating water is solved, the roadbed height can be integrally reduced, and a large amount of manpower, construction period, earthwork, sand and stone, cement, lime and other materials can be saved. The subsequent surrounding roads and even the whole area of the road can be reduced in height, and the indirect economic benefit is difficult to measure. After the polymerization solution is added, the road has good waterproofness, the road is not easy to be damaged in rainy seasons, the service life of the road is prolonged, and the maintenance time is reduced.
After being used, the macromolecular ecological soil polymerization product has organic and inorganic reactions with soil and a cementing material, so that the soil is not polluted or poisoned; the road can be returned to the field for re-cultivation after being abandoned, and the problems of environmental pollution caused by the mining of the traditional road building materials and the waste treatment after the road is abandoned can be effectively solved.
From the general situation, the polymer ecological soil polymerization technology is used for reconstructing the existing road, so that good social benefit and economic benefit can be obtained, and the associated benefit is very great.
