Embodiment Construction

[0018] A chemical reinforcement method for red sandstone, the method is carried out according to the following steps:

[0019] 1. Clean the surface of the red sandstone to be reinforced;

[0020] 2. Prepare magnesium fluorosilicate solution with magnesium fluorosilicate and distilled water at a mass ratio of 1:70;

[0021] 3. Spray the surface of red sandstone evenly with magnesium fluorosilicate solution to saturation, that is, water hangs on the surface of red sandstone;

[0022] 4. After the magnesium fluorosilicate solution is absorbed by the red sandstone, repeat step 3 until the amount of magnesium fluorosilicate solution per square meter of red sandstone surface reaches 10-11 kg;

[0023] 5. Spray evenly on the surface of red sandstone with WD-W02 organic silicon penetration reinforcement produced by Wuhan Lvke Heritage Building Protection Materials Co., Ltd. until saturated;

[0024] 6. Wait until the WD-W02 silicone penetration reinforcement is absorbed by the red s...

Abstract

A chemical stabilization method for arenoso rock features that after the solution of magnesium fluorosilicate is sprayed, the organosilicone consolidating agent WD-WO2 is sprayed.

Description

Technical field: [0001] The invention relates to a reinforcement and protection method for rock mass, and more particularly relates to a chemical reinforcement method for red sandstone. The invention is especially suitable for the protection of cultural relics involving red sandstone. Background technique: [0002] Although rocks have solid crystallization or cementation connections, various rock masses in nature have more or less formed some structural planes with low strength and strong permeability during the diagenesis process and the transformation of internal and external dynamic effects in the later period, resulting in rock mass formation. The properties of the body will deteriorate, which will bring adverse effects to the engineering construction, and even fail to meet the requirements of the engineering construction. In this regard, in addition to improving and solving the problem by changing the structure of the building, improving the properties of the rock mass...
