Abstract

The invention discloses a device and method for testing a curved pipe-roofing machine, and solves the problems that the curved pipe-roofing machine in the prior art is difficult in jacking, deslaggingand posture control, and there is shortage of theory and experiment basis. The device comprises a main unit, a steel pipe joint, and a jacking mechanism. A pile foundation for supporting the jackingmechanism is disposed on the ground, and the jacking mechanism is fixedly connected with the foundation pile. The foundation pile is provided with a cantilever suspension, and the main unit is disposed at one end of the steel pipe joint, wherein the other end of the steel pipe joint passes through the jacking mechanism. The jacking mechanism is provided with a guide mechanism and auxiliary equipment. The main unit is connected with the auxiliary equipment through a pipe in the steel pipe joint, and the guide mechanism is corresponding to the steel pipe joint. The cantilever suspension is disposed at one side of the steel pipe joint, and is connected with the steel pipe joint. According to the invention, the working conditions of underground excavation are simulated through a ground test, thereby achieving the testing of the operation performances of all systems of the curved pipe-roofing machine and the verifying of the construction precision and design reasonability while achieving the jacking of the curved steel pipe joint.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a curved pipe curtain machine test device and a test method thereof. Background technique [0002] The curved pipe curtain method is a new type of non-excavation underground method that uses a small pipe curtain machine to realize soil excavation, and the steel pipe joints are pushed into the soil at the rear to cooperate with the freezing method to form advanced support, and then the main structure is excavated. Space construction technology, for underground projects with shallow buried depth, irregular cross-section, large horizontal span, and complex geological conditions, such as subway stations, underground shopping malls, subway communication channels, tunnel diversion joints, etc., compared with other construction methods, it has less impact on the ground environment , strong adaptability, high security advantages, has a wide range of application prospects. ...
