Novel pipe-jacking self-setting slurry and preparation method thereof
The invention discloses novel pipe-jacking self-setting mud and a preparation method thereof, and belongs to the technical field of pipe-jacking construction.The novel pipe-jacking self-setting mud is prepared from, by mass, 100-120 parts of bentonite, 20-30 parts of slaked lime, 400-600 parts of water, 6-10 parts of a sodium modifying agent, 4-6 parts of a thickening agent, 0.1-0.3 part of a retarder and 1-3 parts of graphite. The novel pipe-jacking self-setting slurry is prepared by the following steps: adding sodium salt into the slurry, fully stirring by using a stirrer, standing to obtain a blank, sequentially adding the sodium salt agent, the slaked lime and the retarder into the blank, fully stirring the thickening agent and water, adding the mixture into the blank, and mixing and stirring indoors at 20-25 DEG C. The novel pipe-jacking self-setting slurry has moderate viscosity, water loss rate and segregation rate; the pipe-jacking anti-drag agent has excellent anti-drag effect in the pipe-jacking construction process, can be self-cured according to the construction period, has the strength of 0.5-0.6 MPa, plays a role in supporting the stratum, and avoids the slurry replacement process.
本发明公开了一种新型顶管自凝泥浆及其制备方法，属于顶管施工技术领域，是由以下质量份数的原料组成：膨润土100~120份、熟石灰20~30份、水400~600份、钠化剂6~10份、增稠剂4~6份、缓凝剂0.1~0.3份和石墨1~3份，其制备方法为：首先将石墨和膨润土与水混合，采用搅拌机充分搅拌并静置，得到胚料，之后将钠化剂、熟石灰、缓凝剂依次加入胚料中，再将增稠剂与水充分搅拌后加入胚料中，在室内20~25℃条件下混合搅拌，得到该新型顶管自凝泥浆，该泥浆具有适中的粘度、失水率、离析率，在顶管施工过程中具备优良的减阻效果，并可根据施工周期自行固化，强度可达0.5~0.6MPa，起到支撑地层的作用，避免了泥浆置换的过程。
