Reinforcing material of permeable hydraulic degraded unconsolidated rock and reinforcing method thereof

Abstract

The invention discloses a reinforcing material of a permeable hydraulic unconsolidated rock. The reinforcing material comprises the following components: low carbon alcohol solution A with a phosphorus source substance as a main solute, wherein, a mineralized coupling agent is dissolved; polyhydroxy low carbon alcohol solution B with a calcium source substance as a main solute, wherein, a hardener and a dispersant are dissolved; and aqueous solution C with ammonium salt as a solute. Penetration operation is performed on the unconsolidated rock by natural flow, spraying, brush coating, soaking or applying methods. The alcohol solution A and the solution B can be mixed and permeated or sequentially permeated respectively, and then the aqueous solution C is permeated after permeation is finished. The reinforcing material has the advantages of easily available raw materials, mild preparation conditions, simple use method, good compatibility with the rock, acid corrosion resistance, obvious reinforcing effect, water soak resistance, no pollution and environmental protection.

Description

technical field [0001] The invention belongs to the field of stone materials and stone cultural relics protection materials, and in particular relates to a reinforcement material for permeable hydraulically degraded loose rock and a reinforcement method thereof. Background technique [0002] Our country has a long history, and many stone cultural relics and ancient buildings are threatened by natural weathering, many of which are already in an endangered state, and are in urgent need of protective materials with excellent performance for reinforcement and protection. At present, most of the commonly used surface protection materials are organic materials. These materials form a network structure dominated by organic substances through cross-linking reactions, and have a certain reinforcement strength. However, the shortcomings of organic materials are also obvious, mainly manifested in short service life, poor weather resistance, and poor compatibility with rocks. Some organ...

AI Technical Summary

Problems solved by technology

[0003] 1. The problem of soluble salts. In osmotic water-based protective agents, inorganic materials are often introduced in the form of salt solutions, so it is difficult to avoid bringing in soluble salts, which will cause damage to salt crystals;

[0004] 2. The problem of reinforcement strength. Due to the solvation of water, after the inorganic salt solution penetrates into the micropores of the rock, what is precipitated is often a powdery substance that is not cross-linked with each other, and the reinforcement effect is not strong;

[0005] 3. The problem of permeability. In order to reduce the harm of soluble salts, insoluble or slightly soluble inorganic substances are often used. However, this conventional solution penetrates very little active ingredient, so it is mostly made into a paste, which affects the protective agent. permeability

However, the reinforcing agent is slightly acidic, which may cause corrosion to calcium-containing rocks. At the same time, the preparation process is more complicated, and the curing time of the reinforcing agent is longer.
