Problems solved by technology

[0002] Crustal weathered materials such as soil often have a large number of voids in their natural state or artificially solidified structure, resulting in poor structural compactness and weak water retention in the environment, even after water immersion, erosion, erosion, etc. After the action, the original strength will be reduced, the structure will be seriously damaged, and serious phenomena such as water conservancy projects, road and railway embankment seepage, soil erosion, and debris flow disasters will appear, causing the country's ecological environment to be destroyed, and even endanger people's lives and property.

Embodiment 1

[0016] Example 1 Preparation of low-strength and high-hydrophobic soil water-blocking agent

[0017] Weigh 10ml of ethanol, 2g of triethanolamine, and 0.5g of sodium polyacrylate in the laboratory, put them into the reactor and stir them evenly, then add 0.1g of methyl silicone oil at 60°C and keep stirring for about 2 hours to obtain the finished soil water blocking agent. After testing, the physical and chemical indicators of the soil water blocking agent are as follows: 3-day unconfined compressive strength increased by 7.1%, and the permeability coefficient decreased by 12.3%.

[0018] Since the prepared soil water blocking agent has the advantages of strong impermeability and good stability, it can be used in fields such as river embankments and dams that do not require high engineering strength.

Embodiment 2

[0019] Example 2 Preparation of soil water-blocking agent with high strength and strong seepage resistance

[0020] Weigh 10ml of ethanol, 10ml of water, 1.5g of sodium dodecylbenzene sulfonate, 0.5g of polyvinyl alcohol, and 0.3g of silica sol in the laboratory, add them into the reaction kettle and mix them evenly, and then continue stirring at 60°C for about 2 hours. The finished soil water-blocking agent was obtained. After testing, the physical and chemical indicators of the soil water-blocking agent were as follows: 3-day unconfined compressive strength increased by 22.6%, and the permeability coefficient decreased by 72.5%.

[0021] The soil stabilized by this material has the advantages of strong impermeability, stability and high structural strength, and can be used in temporary roads for water conservancy projects, highways, railway subgrades and other fields.

Embodiment 3

[0022] Example 3 Preparation of high-strength and high-hydrophobicity soil water-blocking agent

[0023] Laboratory weighs 6ml of ethanol, 10ml of isopropanol, 1.5g of sodium dodecylbenzenesulfonate, 0.3g of glycerin, 0.2g of sodium tetraborate, 0.3g of aluminum oxide, 0.5g of glyceryl stearate, 1.2g of silicone oil, Put all the raw materials into the reactor and mix them evenly, then keep stirring at 60°C for about 2 hours to obtain the finished soil water-blocking agent. After testing, the physical and chemical indicators of the soil water-blocking agent are as follows: 3-day unconfined compressive strength increases 23.1%, and the permeability coefficient is reduced by 70.9%.

[0024] Because the soil structure stabilized by this material is stable, and it has strong anti-seepage and anti-erosion properties to water, it can be used in fields such as anti-seepage and anti-erosion in water conservancy projects.

Abstract

The invention discloses an organic-inorganic hybrid type soil water-blocking agent. A solvent, a penetrating agent and a reinforcing agent are uniformly mixed in a mass ratio of 10-99% to 0.01-30% to0.01-80%, are added into a reaction kettle for being heated and stirred, and a water-blocking agent finished product is obtained after a solution is stable. The organic-inorganic hybrid type soil water-blocking agent has the advantages of being simple in preparation process, small in usage amount, low in cost, long in service life, stable in component, adjustable in structural strength of a curedproduct, and the like. Besides, the material is wide in using range, is convenient for using local materials for a project, and only through adjusting the ratio of main components, the stabilizer material is used for application fields such as water-soil conservation, debris flow placement, roadbed reinforcing, and petroleum and gas development, so that engineering cost is greatly reduced, and construction time is shortened.

Description

technical field [0001] The invention relates to new materials for highway and railway subgrades, anti-seepage, anti-freezing and water and soil conservation of water conservancy projects, in particular to an organic-inorganic hybrid soil water-blocking agent. Background technique [0002] Crustal weathered materials such as soil often have a large number of voids in their natural state or artificially solidified structure, resulting in poor structural compactness and weak water retention in the environment, even after water immersion, erosion, erosion, etc. After the action, the original strength is reduced, the structure is seriously damaged, and serious phenomena such as water conservancy projects, road and railway embankment seepage, soil erosion, and debris flow disasters occur, causing damage to the national ecological environment, and even endangering people's lives and property. In this regard, reasonable modification measures are adopted to treat fine particles and t...
