Long-distance pipe jacking construction method for urban underground pipe gallery
The invention belongs to the technical field of urban underground comprehensive pipe galleries, and particularly relates to a long-distance pipe jacking construction method for an urban underground pipe gallery. According to the method, the thixotropic slurry can be rapidly and efficiently stirred by reasonably matching the raw material composition of the thixotropic slurry and using a combined stirrer in a matched mode, and the outstanding pipe jacking resistance reduction and pipe hole reinforcement effects are achieved in the long-distance pipe jacking construction process, so that the soil collapse risk in the urban underground pipe gallery construction process is greatly reduced. The method has the advantages that the structure of the combined stirrer is reasonable and effective, continuous slurry loading operation is simple and efficient, slurry filling is flexible and controllable, the problem that the amount of the slurry in a certain barrel is too large or too small is not prone to occurring, and the overall stirring production and use efficiency of the slurry is high.
本发明属于城市地下综合管廊技术领域，尤其涉及一种城市地下管廊长距离顶管施工方法。本发明通过合理搭配触变泥浆的原料组成，再配合使用组合式搅拌机的方式，使得触变泥浆可以快速高效地搅拌获得，并且在长距离顶管施工过程中发挥突出的顶管减阻和管洞加固作用，大大降低城市地下管廊施工过程中的土体坍塌风险。本发明还具有以下优点：组合式搅拌机自身结构合理有效，泥浆连续装料操作简单高效，泥浆装填料灵活可控，不易出现某桶泥浆的量过多或过少的问题，以及泥浆的整体搅拌生产使用效率高的优点。
