Anti-settling mud and grouting slurry applied to shield tunneling construction
The invention discloses anti-settling mud and grouting slurry applied to shield tunneling construction. The anti-settling mud applied to shield tunneling construction comprises the following components: calcium-based bentonite, sodium-based bentonite, lime, cement, cellulose derivatives and high-molecular polymers. The grouting slurry applied to shield tunneling construction comprises a solution Aand a solution B; the solution A comprises the anti-settling mud applied to shield construction and water; and the solution B is sodium silicate. The anti-settling mud and the grouting slurry appliedto shield tunneling construction are non-toxic and environmentally friendly, can be used for filling the peripheral gap of the upper part of a shield tunneling machine, can also be used for buildinga protection mud film before opening a bin and replacing cutters under pressure during shield tunneling construction; the anti-settling effect is good; and the built mud film is high in strength.
本发明公开了一种盾构施工用防沉泥和一种盾构施工用注浆浆液，盾构施工用防沉泥的组分包括钙基膨润土、钠基膨润土、石灰、水泥、纤维素衍生物、高分子聚合物。盾构施工用注浆浆液包括A液和B液，所述A液包括盾构施工用防沉泥和水，所述B液为水玻璃。本发明无毒环保，既可以用于充填盾构机上部外周的缝隙，又可以用于盾构带压开仓换刀前建立防护泥膜，防沉降效果好，建立泥膜强度高。
