Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with specific embodiments. This embodiment adopts the technical solution of the present invention for construction, which provides detailed implementation and specific operation process, but the scope of protection of the present invention is not limited to the following embodiments.

[0013] Taking a shield tunnel construction project as an example, during the construction process, the use of shield equipment and the changes of various construction parameters in shield tunneling were monitored in real time. Forming method Overhaul and replacement of shield equipment was carried out during construction.

[0014] In the first step, when the shield tunneling reached the 1500th ring, by checking the wear and tear of the shield equipment, it was found that some of the cutters on the shield cutterhead were worn out, which seriously affected the efficiency of the shield cutterhead in cutting soil. ...

Abstract

The invention discloses a formation method for construction overhaul environment of a shield tunnel, comprising the following steps: firstly, shield equipment required for overhaul or replacement, positions of the shield equipment, the number of the shield equipment, and the reinforcement form, the reinforcement range and the reinforcing strength of the peripheral soil mass of a shield are determined according to geological materials of sections of a construction tunnel and technical parameters of a shield machine; secondly, drilling is performed from the inside of the shield to the outside of the shield, and a reinforced pipe is extended out of the shield to form a reinforced pipe network; thirdly, the peripheral soil mass of the shield is reinforced. The formation method for the construction overhaul environment of the shield tunnel not only is not limited by the tunnel embedded depth, ground buildings and environmental conditions but also avoids the possible danger of the air pressure environment on personal safety and health, thereby the formation method has the advantages of high safety and strong serviceability and provides a formation method for a safe and reliable operation environment for shield construction of the tunnel and particularly for overhaul and replacement of the shield equipment under a river for a large-diamond long-distance tunnel project, consequently the operation safety of operators is guaranteed.

Description

Technical field: [0001] The invention relates to a tunnel shield construction method, in particular to a method for forming a shield tunnel construction and maintenance environment, and belongs to the field of construction engineering. Background technique: [0002] Since the 20th century, tunnel shield tunneling engineering technology in various countries in the world has made rapid progress, and has made remarkable achievements. Large-diameter, long-distance cross-sea and river-crossing tunnels have increasingly appeared in countries, regions and Inter-city highway, railway traffic engineering. In the construction process of these large-diameter, long-distance tunnel projects, due to factors such as different geological and hydrological conditions in various regions, the existence of underground unknown obstacles, the failure of construction equipment, and the service life of the equipment itself, no matter what type of tunnel is used There is a possibility of overhauling...
