Abstract

The invention discloses a method for the underground storage heat preservation on a shield tunneling machine apparatus under extreme low-temperature weather. The method comprises the following steps of a step I, isolating and enclosing a shield tunneling machine and a surrounding space thereof, so as to form a finite space; a step II, heating the finite space, and maintaining a set temperature range. According to the method, through enclosing the periphery of the shield tunneling machine, the ambient temperature of the periphery of the shield tunneling machine is promoted by a wide margin by carrying out non-open flame heating in an enclosure space, and the problems of the damage and sealing aging of a component and the harm of a pump body, which is caused by the solidification of hydraulic oil, and the like, after the shield tunneling machine is stored through the winter in a very frosty area are effectively solved.

Description

technical field [0001] The invention relates to the field of shield method construction in tunnel engineering construction technology. More specifically, the present invention relates to a method for storing and insulating shield machine equipment underground in extremely low-temperature weather. Background technique [0002] With the development of the shield tunneling business, subway tunnels, comprehensive pipe corridors, and sewage treatment have successively developed in northern China, where shield tunneling machines are used as the main construction method. In order to reduce the construction cost, construction in the extremely cold winter will be avoided in most areas of the north, and the shield machine equipment will be stored for winter insulation, and the construction will be carried out after the temperature rises. In order to reduce the impact of the low temperature environment on the equipment structure and components, and to avoid the impact of frost on the ...
