Problems solved by technology
[0003] The core of the freezing method is the freezer constructed in the ground, which generally consists of three parts: a freezing pipe, a liquid supply pipe, and a freezing end. At present, the end of the freezer is generally welded with steel, and it is discarded directly after construction. At the same time, the traditional The current freezer does not have the function of cooling delivery adjustment, and it is difficult to effectively monitor and control the cooling effect. Therefore, it is very necessary to develop a tunnel freezing smart terminal and use its specific application method to solve the above technical problems.

The invention discloses a tunnel freezing intelligent terminal and its application method, system, equipment and medium. Tunnel freezing intelligent terminal, including: terminal body, the terminal body has a cavity for the return water to pass through; liquid supply pipe, the liquid supply pipe runs through the cavity of the terminal body; return water pipe, one end of the return water pipe and the terminal body The side wall is connected, and the return pipe is connected with the cavity; the flow meter is installed on the liquid supply pipe to monitor the flow of the liquid supply pipe; the proportional valve is installed on the return pipe to control the flow in the return pipe. The application method of the tunnel freezing intelligent terminal includes: obtaining the flow data of the liquid supply pipe monitored by the flowmeter, the temperature data in the return pipe and the temperature data in each temperature measuring hole, and the monitoring and measurement data of the tunnel freezing surface; The network analyzes the above data to obtain the freezing effect, and adjusts the proportional valve according to the freezing effect to adjust the flow. The present invention further provides a tunnel freezing intelligent terminal application system, equipment and medium.
Description
technical field [0001] The invention relates to the technical field of tunnel construction freezing, in particular to an intelligent tunnel freezing terminal and an application method, system, equipment and medium thereof. Background technique [0002] The freezing method is to use artificial refrigeration technology to prepare low-temperature refrigerant, and use the pipeline circulating pump to transport the low-temperature refrigerant into the stratum, to freeze the loose soft soil into a frozen soil body with certain strength and water-sealing ability, so as to realize the reinforcement of the stratum. . At present, the artificial freezing method is widely used in the reinforcement of underground projects such as tunnels, mines, and comprehensive pipe corridors. [0003] The core of the freezing method is the freezer constructed in the stratum, which generally consists of three parts: the freezing pipe, the liquid supply pipe and the freezing end. The tunnel freezer do...
