Embodiment

[0034] A preparation method for grouting fluid, comprising the following steps:

[0035] Dissolve the suspending agent and dispersing agent in water according to the proportioning weight, mix evenly, add glass microspheres to soak, stir well to form a suspension. The suspending agent here is commercially available nano-silica sol, the dispersant is commercially available sodium citrate, and the particle size of glass microspheres is 40-70 mesh.

[0036] Add wood flour to the suspension and stir for 15-30 minutes, then add foaming agent and stir for 15-30 minutes to form a mixed solution, and the mixed solution is ultrasonically oscillated for 30 minutes, and the frequency of ultrasonic oscillation is 25KHz. The fineness of the wood flour here is 40-70 mesh, and the moisture content is 6%-8%. The foaming agent is a composite foaming agent uniformly mixed with animal cement foaming agent and sodium lauryl sulfate.

[0037] Mix and stir cement, sand and bentonite evenly to form...

Embodiment 9

[0043] A preparation method of grouting liquid, the difference from Example 7 is that 10 g of hydroxymethyl cellulose is added before the wood powder is added to the suspension.

Embodiment 10

[0045] A preparation method of grouting liquid, the difference from Example 7 is that 12 g of hydroxymethyl cellulose is added before the wood powder is added to the suspension.

Abstract

The invention relates to a grouting liquid, a preparation method and application of the grouting liquid in corrosion fracture zone reinforcement treatment and relates to the technical field of fracture zone reinforcement, and the grouting liquid is prepared from the following raw materials in parts by weight: 60-90 parts of cement, 80-100 parts of sand, 28-36 parts of bentonite, 5-10 parts of wood flour, 80-150 parts of glass beads, 1.2-2 parts of a composite foaming agent, 12-16 parts of a suspending agent, 4-8 parts of a dispersing agent and 460-600 parts of water. Wherein the composite foaming agent is composed of an animal cement foaming agent and lauryl sodium sulfate, and the weight ratio of the glass beads to the wood flour is 1-3; the preparation method comprises the following steps: dissolving the suspending agent and the dispersing agent in water according to the weight ratio, uniformly mixing, adding the glass beads, soaking, and fully stirring to form a suspension; adding wood flour into the suspension, uniformly stirring, adding the foaming agent, and uniformly mixing to form a mixed solution; uniformly mixing and stirring the cement, the sand and the bentonite to form a mixture; and mixing the mixed solution with the mixture, adding an early strength agent, and uniformly stirring to obtain the grouting liquid. The method has the advantage that the fracture zone can be rapidly reinforced.

Description

technical field [0001] The present application relates to the technical field of broken zone reinforcement, and in particular to a grouting liquid, a preparation method and its application in the reinforcement treatment of the eroded broken zone. Background technique [0002] The deformation of the mountains on both sides of the river due to geological movement will cause cracks in the rocks. If the broken rocks fall, they will cause harm to the waterway and water operators. In order to ensure the safety of the waterway, it is necessary to survey the mountains on both sides of the waterway to discover risks and hidden dangers in advance and take preventive measures. [0003] In the prior art, a flexible anti-rockfall net is generally dragged and guided on the rock surface, and the rockfall is buffered by using the protective net. The protective net is fixed on the rock mass by anchor cables. [0004] The inventor believes that the above technical solution has the following...
