新型溶胶树脂浆液在孔隙-微裂隙岩层治理中的应用

Application of New Sol Resin Grout in Pore and Micro Fissures-rock management

摘要: 新型溶胶树脂化学浆液分为甲液、乙液,甲液由三聚氰胺改性脲醛树脂浆液、聚酯树脂和聚乙烯醇配制,乙液由稀释浓度为10%～25%的草酸及肼基碳硫酰胺配制。新型浆液可采用甲液单注及双液注浆的使用方式。通过现场应用实践,发现新型溶胶树脂化学浆液对于一般水泥浆液难于注入的富水低渗的孔隙-微裂隙含水岩层的可注性较好,封水效果明显。

Abstract: New sol resin chemical grout is divided into liquid A and liquid B.Liquid A is prepared by melamine-modified urea-formaldehyde resin,polyester resin and polyvinyl alcohol.Liquid B is prepared by oxalic acid(10%～ 25% concentrations) and hydrazine base carbon sulfamides.The new grout can be used with liquid A and B together or liquid A only.The field application practice shows that the groutability of the new sol resin chemical grout for rich water low permeability aquifer rocks with pore and micro fissures is good,and the water plugging effect is obvious.
