Synchronous grouting slurry suitable for sandy water-rich stratum
The invention discloses synchronous grouting slurry suitable for a sandy water-rich stratum. The synchronous grouting slurry comprises cement slurry, water glass and double slurry prepared from the cement slurry and the water glass. The cement slurry comprises cement, bentonite and water, and the cement slurry comprises the following components in proportion: 450 parts of cement; 75 parts of bentonite; and 785 parts of water. The modulus range of the water glass is 2.8-3.5, and the value range of the volume ratio of the cement slurry to the water glass is 0.1-0.2. According to the invention, from the aspects of viscosity, setting time, compressive strength, permeability and the like, system test, comparison, selection and optimization are carried out, and the synchronous grouting slurry suitable for sandy water-rich stratum is researched and developed.
本发明公开了一种适用于砂性富水地层的同步注浆浆液，包括：水泥浆、水玻璃及由所述水泥浆与所述水玻璃配制而成的双浆液；所述水泥浆包括水泥、膨润土及水，所述水泥浆成分比例为：水泥450；膨润土75；水785；所述水玻璃模数范围为2.8～3.5，所述水泥浆与所述水玻璃的体积比的取值区间为0.1～0.2。根据本发明，从粘度、凝结时间、抗压强度、渗透性等方面，进行系统试验、比选和优化，研发适用于砂性富水地层的同步注浆浆液。
