Pipe jacking thixotropic slurry capable of being cured in situ and grouting system
The invention discloses pipe jacking thixotropic slurry capable of being cured in situ, and belongs to the technical field of pipe jacking slurry main body construction, the pipe jacking thixotropic slurry comprises a slurry main body and curing slurry, the slurry main body comprises bentonite, a thickening stabilizer, a dispersing agent, an additive and xanthan gum, and the curing slurry comprises high-calcium fly ash, cement and gypsum. The invention further provides a grouting system of the pipe jacking thixotropic slurry capable of being cured in situ, the grouting system comprises a first preparation machine, a second preparation machine, a driving pump, a controller and a grouting pipe, and the first preparation machine is used for preparing a slurry body; the second preparation machine is used for preparing curing slurry; the grouting pipe abuts against the jacking pipe, and one end of the grouting pipe is detachably connected with the driving pump through the conversion assembly. The method solves the problem that thixotropic slurry needs to be replaced after pipe jacking construction in the prior art, and great disturbance is caused to a soil body, and is remarkable in acting effect and suitable for wide popularization.
本发明公开了一种可原位固化的顶管触变泥浆，属于顶管泥浆主体施工技术领域，包括泥浆主体和固化浆液，泥浆主体包括：膨润土、增稠稳定剂、分散剂、添加剂和黄原胶，固化浆液包括：高钙粉煤灰、水泥、石膏。本发明还提供了一种可原位固化的顶管触变泥浆的注浆系统，包括第一制备机、第二制备机、驱动泵、控制器、注浆管，其中第一制备机用于制备泥浆主体；第二制备机用于制备固化浆液；注浆管与顶管抵接、且一端通过转换组件与驱动泵可拆卸连接。本发明解决现在技术所存在的触变泥浆在顶管施工结束后需要进行置换，对土体产生极大扰动的问题，作用效果显著，适于广泛推广。
