The invention discloses a complex stratum pipe-jacking working well and a construction technology thereof, and belongs to the technical field of pipe-jacking working well construction. The complex stratum pipe jacking working well construction technology comprises the following steps that the well position is determined; steel sheet pile construction; grouting reinforcement is conducted, specifically, grouting in the working well is conducted through drilling, and then cement or cement and water glass slurry are injected into the position 0-3 m below the pit bottom in a hole; working well outer grouting is conducted from 1.5 m below the ground to 3 m below the well bottom, and the lower portion of the working well outer grouting is connected with a well inner grouting soil body; after grouting is finished, purlin enclosing, supporting and excavation construction is carried out; after excavation is conducted to the bottom of the working well, reinforcing steel bars are bound at the bottom of the well, a concrete bottom plate is poured, equipment is installed in the working well, and after all the equipment is installed and debugged in place, portal steel sheet piles are cut, and pipelines are jacked. The complex stratum pipe jacking working well construction technology is an economical and safe technical measure for complex stratum construction working well construction, the problems of difficult precipitation and the like are solved, and the working efficiency of working well manufacturing is greatly improved.
本发明公开了一种复杂地层顶管工作井及其施工工艺，属于顶管工作井施工技术领域。该复杂地层顶管工作井施工工艺包括以下步骤：确定井位；钢板桩施工；注浆加固，工作井内注浆是通过钻孔，再向孔内坑底以下0‑3m注入水泥或水泥和水玻璃浆；工作井外注浆从地面以下1.5m至井底以下3m，下部与井内注浆土体相连；注浆结束后进行围檩、支撑、开挖施工；开挖至工作井底后，在井底绑扎钢筋浇筑混凝土底板，工作井内安装设备，设备全部安装调试到位后，切割洞门钢板桩，管道顶进。本发明的复杂地层顶管工作井施工工艺是复杂地层施工工作井比较经济、安全的技术措施，解决了降水困难等问题，极大的提高了工作井制作的工效。
