Problems solved by technology

Most of the existing liquid soil curing agents are strongly acidic or alkaline, which will not only bring great danger to the operator during use, but also cause certain damage to the ecological environment around the place of use.
In addition, the existing liquid soil solidifiers have poor compressive capacity, water stability and freezing stability, and their production process not only consumes a lot of energy, but also causes environmental pollution to varying degrees.

Embodiment 1

[0029] Embodiment 1 gets each raw material component of soil liquid solidifying agent by following percentage by weight:

[0030] Diethanol monoisopropanolamine 45%-55%, sodium polycarboxylate 20%-30%, calcium lignosulfonate 10%-20%, polyethylene OP-105%-10%, α-alkenyl sulfonic acid Sodium 2%-5%.

[0031] Among them, preferably, the lignosulfonate is calcium lignosulfonate.

[0032] After mixing the above-mentioned raw material components according to the above-mentioned weight percentage, dilute with pure water according to the weight ratio of 1:1; inject the diluted mixture into the reactor for chelation reaction for 48 hours, and wait for the temperature to drop to 30° after the reaction is completed Pack it into the package at -50°. At this time, the pH value of the curing agent is 10-12, and the density is 1.1g / cm-1.2g / cm 3 , The solid content is 45%-50%.

Embodiment 2

[0034] Embodiment 2 gets each raw material component of soil liquid solidifying agent by following weight percentage:

[0035] Diethanol monoisopropanolamine 50%-55%, sodium polycarboxylate 25%-30%, calcium lignosulfonate 15%-20%, polyethylene OP-108%-10%, α-alkenyl sulfonic acid Sodium 3%-5%.

[0036] Among them, preferably, the lignosulfonate is calcium lignosulfonate.

[0037] After mixing the above-mentioned raw material components according to the above-mentioned weight percentage, dilute with pure water according to the weight ratio of 1:1; inject the diluted mixture into the reactor for chelation reaction for 48 hours, and wait for the temperature to drop to 30° after the reaction is completed Pack it into the package at -50°. At this time, the pH value of the curing agent is 10-12, and the density is 1.1g / cm-1.2g / cm 3 , The solid content is 45%-50%.

Embodiment 3

[0039] Embodiment 3 gets each raw material component of soil liquid solidifying agent by following percentage by weight:

[0040] Diethanol monoisopropanolamine 52%, sodium polycarboxylate 28%, calcium lignosulfonate 18%, polyethylene OP-108%, sodium α-olefin sulfonate 4%.

[0041] Among them, preferably, the lignosulfonate is calcium lignosulfonate.

[0042] After mixing the above-mentioned raw material components according to the above-mentioned weight percentage, dilute with pure water according to the weight ratio of 1:1; inject the diluted mixture into the reactor for chelation reaction for 48 hours, and wait for the temperature to drop to 30° after the reaction is completed Put it into the package in minutes, at this time, the pH value of the curing agent is 10-12, and the density is 1.1g / cm-1.2g / cm 3 , The solid content is 45%-50%.

Abstract

The invention discloses a liquid soil solidifying agent and a preparation method, a using method and the application thereof. The liquid soil solidifying agent is prepared by adding water to dilute the following raw materials in percent by weight: 45-55% of diethanol monoisopropanolamine, 20-30% of sodium polycarboxylate, 10-20% of lignosulfonate, 5-10% of polyethylene OP-10 and 2-5% of sodium alpha-alkenyl sulfonate. The liquid soil solidifying agent is simple in production technology, can control dust pollution after addition into cement, effectively shortens the solidifying time of sludge solidification, and is small in addition amount, high in strength, low in cost and good in curing stability effect.

Description

technical field [0001] The invention relates to the technical field of solidified soil and environmental engineering, in particular to a liquid solidifying agent for soil and its preparation method, use method and application. Background technique [0002] Soil liquid solidifier is a new type of engineering material synthesized from various inorganic and organic materials to solidify various soils and improve soil engineering performance. In engineering construction, the use of soil solidification can replace gravel, gravel and other traditional road construction materials, and has the advantages of less consumption, local materials, fast curing speed, high early strength, saving construction time, and reducing project cost. It has been widely used in many fields such as highway subgrade, railway subgrade, embankment curing, building foundation, airport runway curing, slope fixing, etc. [0003] In the prior art, soil curing agents are mainly divided into two types: solid s...
