极小半径曲线顶管是一种新型的非开挖地铁车站建造技术,在国内尚无应用先例。极小半径曲线顶管机室内测量试验用于验证所研制样机的施工参数,试验通过模拟顶推,测量顶管机临界推力与支座反力,验证了极小半径曲线顶管机推进设备设计的合理性,为极小半径曲线顶管机的设计与施工奠定了基础。
Minimal radius curve pipe jacking is a new type of trenchless metro station construction technology, there is no precedent in the domestic application. The test of minimum radius curve pipe jacking machine indoor is used to verify the construction parameters of the prototype. The test measures the jacking machine thrust and bearing reaction force by simulating jacking, and verifies the design of the equipment The rationality of this system has laid the foundation for the design and construction of the pipe jacking machine with a very small radius.
