Temperature controller device capable of measuring frost heaving pressure

Abstract

The invention discloses a temperature controller device capable of measuring the frost heaving pressure. The temperature controller device capable of measuring the frost heaving pressure comprises an upper sealing plate, a pressure release pipe, a lower sealing plate, a base cone, a temperature control pipe, a liquid feeding pipe, a liquid returning pipe, a flow guiding pipe, a bypass pipe, a pressure gauge and a pressure release valve, wherein a liquid feeding pipe installation hole and a liquid returning pipe installation hole are formed in the upper sealing plate, steel scale type buckling pipes used for fixing the liquid feeding pipe and the liquid returning pipe are installed in the liquid feeding pipe installation hole and the liquid returning pipe installation hole respectively, the liquid feeding pipe penetrates through the steel scale type buckling pipe in the liquid feeding pipe installation hole, the upper sealing plate is connected with the upper port of the flow guiding pipe and the upper port of the temperature control pipe, the lower port of the flow guiding pipe and the upper port of the pressure release pipe are fixedly connected through connecting steel bars and are communicated through liquid, and the lower port of the pressure release pipe is fixedly connected with the side wall of the base cone. By the adoption of the temperature controller device capable of measuring the frost heaving pressure, the frost heaving pressure generated in a stratum when the stratum is frozen can be measured and released, temperature control and pressure release are conducted in a combined mode on a basis, and thus the temperature control function of temperature control holes can be brought into play more effectively.

Description

technical field [0001] The invention relates to a temperature controller device used in the rock mass freezing method construction technology, in particular to a temperature controller device capable of measuring frost heaving pressure. Background technique [0002] In order to mine underground resources, build underground power stations, underground railways, transoceanic tunnels, etc., people must understand the physical and mechanical characteristics of deep rock and soil, and use unconventional special construction methods to excavate them. At present, in deep space excavation, the most commonly used method is artificial freezing construction technology, the core of which is to use artificial refrigeration to send low-temperature refrigerant into weak strata with a certain water content and groundwater flow rate, so that the water in the stratum and The surrounding rock and soil are frozen to form a frozen wall with high strength, large elastic modulus and good impermeab...
