Problems solved by technology

[0004] The invention aims at setting up a stone factory in the construction of various roads in my country due to high requirements for the materials of crushed stones used, thereby increasing the processing cost and transportation cost, thereby making the cost of road construction remain high, and digging when building roadbeds. A large number of weathered rocks, soil intercalated stones, mountain stones, etc. due to low strength and mixed soil and rocks, cannot be used on the pavement base, resulting in a large number of abandoned squares, occupying land, and increasing the cost of road construction. Provide a Geotechnical curing agent and manufacturing method thereof, and road structure and manufacturing method thereof

Embodiment 1

[0055] First, after adding 350 kg of water to the reactor, open the reactor; secondly, add 80 kg of iron sulfate and 140 kg of sodium sulfate to the reactor in turn, and stir for 30 minutes; again, slowly add 180 kg of concentrated sulfuric acid Then, add 10 kilograms of DuPont FSN-100 fluorocarbon surfactant, 30 kilograms of triethanolamine, 80 kilograms of calcium lignosulfonate superplasticizer, 10 kilograms of ten Sodium dialkyl sulfate and 90 kg of TH-928 polycarboxylate high-performance water reducer were added to the reaction kettle in sequence, and stirred for 2 hours; finally, the geotechnical curing agent was obtained by exiting the kettle.

Embodiment 2

[0057] First, after adding 350 kg of water into the reactor, open the reactor; secondly, add 80 kg of ferric chloride and 210 kg of sodium chloride into the reactor in turn, and stir for 30 minutes; again, add 150 kg of concentrated Hydrochloric acid is slowly added in the reaction kettle and stirred for 30 minutes; then, 5 kilograms of DuPont FSN-100 fluorocarbon surfactant, 50 kilograms of triethylenepropanolamine, 100 kilograms of sodium lignosulfonate water reducer , 10 kg of polyvinyl alcohol and 200 kg of TH-928 polycarboxylate high-performance water reducer were added to the reaction kettle in turn, and stirred for 2 hours; finally, the geotechnical curing agent was obtained by exiting the kettle.

Embodiment 3

[0059] First, after adding 350 kg of water to the reactor, open the reactor; secondly, add 200 kg of ferric chloride and 70 kg of potassium sulfate to the reactor in turn, and stir for 30 minutes; again, add 150 kg of concentrated sulfuric acid Slowly add in the reaction kettle, and stir for 30 minutes; Then, 12 kilograms of FC-4430 fluorocarbon surfactant of 3M company, 48 kilograms of triethanolamine, 80 kilograms of aliphatic superplasticizer, 9 kilograms of six Sodium metaphosphate and 53 kg of TH-928 polycarboxylate high-performance water reducer are added to the reaction kettle in sequence, and stirred for 2 hours; finally, the rock soil curing agent can be obtained by taking out the kettle.

[0060] Most weathered rock-soil aggregates are negatively charged. When they are used to build road subgrades, under the action of pressure, weathered rock-soil aggregates approach a certain distance, which will generate mutual repulsion, resulting in a decrease in compaction. Betwe...

Abstract

The invention relates to a soil and rock curing agent and a manufacturing method thereof and a road structure and a manufacturing method thereof. The soil and rock curing agent comprises a first metal salt, a second metal salt, water, acid, an early strength agent, a water reducing agent, a dispering agent, a fluorocarbon surfactant and a polycarboxylate surfactant. Widely distributed soil, decayed rock, building rubbish and tailing resource are main materials and the soil and rock curing agent is added, thereby being capable of reducing road cost; road roadbed, airport foundation, port foundation and water resource facilities built with the soil and rock curing agent have the advantages of short curing period, water resistance, cold resistance and hairline crack prevention, thereby improving compression strength and bending strength and greatly reducing construction cost.

Description

technical field [0001] The invention relates to a curing agent and a manufacturing method thereof, a road structure and a manufacturing method thereof, in particular to a rock soil curing agent and a manufacturing method thereof, a road structure and a manufacturing method thereof. Background technique [0002] After mankind entered the 20th century, the level of science and technology has greatly improved, the scale of economic production has expanded rapidly, and the population has expanded extremely. The development and destruction of natural resources have also reached an astonishing degree, and the exhaustion of resources and energy has increased. Facing the situation of resource shortage and environmental change, people have to think about the sustainable development of social economy. [0003] In the construction of various highways in my country, especially the subgrade of high-grade highways, the upper base layer is mostly made of fly ash gravel or cement stabilized...
