Abstract

The invention discloses a system for monitoring a temperature field of a shield shell. The system comprises an internal surface temperature sensor, a temperature gradient sensor and a computer test system, wherein the internal surface temperature sensor is arranged on an internal surface of the shield shell and monitors the internal surface temperature of the shield shell; the temperature gradient sensor is arranged in a preset hole of the shield shell and monitors the temperature gradient of the thickness of the shield shell and determines the external surface temperature of the shield shell; and the internal surface temperature sensor and the temperature gradient sensor are connected with the computer test system through a lead. The system is mainly applicable to dynamic monitoring of asurface temperature field of the shield shell during the penetration of a frozen soil reinforcement body in the process of shield starting and receiving; the frozen state of soil bodies at the periphery of the shield shell can be mastered; the danger of water burst and sand burst is avoided; construction safety is guaranteed; and actual reference can be provided for de-freezing of frozen soil as necessary.

Description

technical field [0001] The invention belongs to the technical field of temperature measurement, and relates to a temperature measurement system used in shield tunnel construction, in particular to a shield casing temperature field monitoring system. Background technique [0002] The artificial ground freezing method (referred to as "freezing method") is to use artificial refrigeration technology to freeze the water in the ground, turn the natural rock and soil into frozen soil, increase its strength and stability, and serve as a support structure to isolate groundwater. In connection with underground engineering, its essence is to use artificial refrigeration to temporarily change the properties of rock and soil to strengthen the formation. Due to its advantages of strong adaptability, high strength, good water-proof performance, and small environmental impact, it is widely used in various projects such as mines, tunnels, foundation pit engineering, shield starting and recei...
