Abstract

The invention discloses a foaming agent for a light grouting material. The foaming agent comprises the following components, by weight: 5-8 parts of alkylphenol polyoxyethylene, 1-3 parts of sodium alcohol ether sulphate, 2-5 parts of sodium dodecyl sulfate, 3-6 parts of fatty alcohol ammonium sulfate, 1-2 parts of polyacrylamide, 1-2 parts of sodium carboxymethyl cellulose, 2-3 parts of xanthan gum, 0.5-2 parts of modified carbon foam powder and 80-100 parts of water. The foaming agent provided by the invention has high foaming capacity and strong foam stability; and the produced foam has surface adsorption film with high strength, and the foaming agent has advantages of good temperature adaptability, biodegradability, no toxicity or corrosion, low cost and easiness for usage.

Description

technical field [0001] The invention relates to a foaming agent, in particular to a foaming agent for lightweight grouting materials. Background technique [0002] In underground engineering, due to soil excavation and excessive pumping of groundwater, the geological environment will be damaged, and then geological disasters such as surface subsidence, subsidence, and building deformation will be caused. In order to prevent damage caused by excessive surface settlement, it is often necessary to adopt grouting technology for backfilling and grouting in time after the excavation of underground works is completed. Backfill grouting is mainly used in mines, water conservancy and hydropower, roads and railways, military and civil air defense and other fields. In mine filling, the mined space is filled with various sands, stones and other materials, so as to support the surrounding rock, prevent or limit the large-scale movement of the surrounding rock and surface subsidence; in...
