The invention relates to the technical field of constructional engineering, in particular to a pipe-jacking working well structure which comprises a bottom plate arranged at the bottom of a working well; the side wall assembly is arranged on the peripheral side of the bottom plate and used for supporting soil on the peripheral side of the bottom plate to form a construction cavity; each group of back wall assembly comprises a wall body and a wall pier; the wall body is arranged on the bottom plate and is used for supporting the pipe jacking machine to jack a jacking pipe; the wall pier is arranged on the side, away from the jacking direction of the jacking pipe, of the wall and used for abutting against and supporting the wall. The wall pier is arranged in a step shape, and the height of the wall pier is gradually decreased in the direction away from the wall body. The side wall assemblies are provided with first open holes corresponding to the back wall assemblies, the first open holes are used for jacking pipes to penetrate through, and the problems that the supporting capacity of a back wall of an existing jacking pipe working well structure is poor, and the back wall abuts against soil on the side wall of a working well through the side wall to resist horizontal acting force generated in the jacking process are solved. And the side wall is easy to damage.
本发明涉及建筑工程技术领域，具体涉及一种顶管工作井结构，包括：底板，设置在工作井的底部；侧墙组件，设置在底板的周侧，用于对其周侧的土壤进行支撑以形成施工空腔；至少一组背墙组件，每组背墙组件包括墙体以及墙墩；墙体设置在底板上，用于支撑顶管机顶进顶管；墙墩设置在墙体背离顶管的顶进方向的一侧，用于抵接并支撑墙体；墙墩呈台阶状设置，且墙墩的高度朝背离墙体的方向逐渐递减；其中，侧墙组件上对应每组背墙组件均设有一个第一开孔，第一开孔用于顶管穿过，解决了现有的顶管工作井结构后背墙的支撑能力较差，后背墙通过侧墙抵接工作井侧壁的土壤以抵抗顶进过程中产生的水平作用力，容易导致侧墙损坏的技术问题。
