Abstract

The invention provides a comprehensive construction system and method for a mechanical slurry balance pipe-jacking tunnel to penetrate through an existing structure downwards, and belongs to the technical field of pipe-jacking construction. The comprehensive construction system comprises a pipe-jacking construction system, a comprehensive support monitoring system and an existing structure protection system. Through cooperation of the three parts of systems, deformation and settlement of the existing structure on the upper portion can be reduced, the change condition of the existing structure in a construction project and the real-time state in the pipeline jacking process are monitored in real time through a stress-strain acquisition unit, data are transversely compared, and unsafe accidents are avoided. The comprehensive construction system has the advantages that the influence on the existing structure in the pipe jacking construction process can be controlled, the pipe jacking effect is controllable and adjustable, the stability of a top plate unit is good when jacking force is dissipated, and structural pavement is conducted on a stratum before a pipe jacking tunnel is excavated.

Description

technical field [0001] The invention belongs to the technical field of pipe jacking construction, and specifically discloses a comprehensive construction system and method for a mechanical mud-water balance pipe jacking tunnel passing through existing structures. Background technique [0002] Pipe jacking construction is a kind of non-grooving construction technology. It refers to the theorem generated by jacking equipment in the working well to overcome the friction between the pipeline and the surrounding soil, and push the pipeline into the ground according to the design requirements. It has high construction accuracy. , Applicable to a wide range of pipe diameters, applicable to various geological conditions and other advantages. [0003] With the rapid development of the economy, there are relatively many municipal constructions in the city, the use of space on the ground is limited and there is a large traffic pressure, and more pipeline constructions are gradually usi...
