AI Technical Summary

Technical Problem

In the existing technology, it is not easy to synchronize the filling of water in the delamination chamber and the hydraulic chamber, and it is not easy to completely expel the gas in the chamber, resulting in inaccurate monitoring results of the delamination water's superstatic water pressure.

Method used

Using the principle of communicating vessels, the separation chamber and the hydraulic chamber are designed as communicating vessels. The device posture is adjusted by a rotatable platform so that the exhaust pipe is on top, achieving synchronous water filling and exhaust. Then, a screw piston pressurizing device is used to pressurize the hydraulic chamber and monitor the superstatic water pressure of the separation water.

Benefits of technology

This method enables simultaneous water filling and venting of the exfoliation chamber and the hydraulic chamber, ensuring the accuracy of monitoring results, avoiding the influence of pressure differences and gas within the chambers, and improving the reliability of the experiment.

Abstract

This invention discloses a method for monitoring the superstatic water pressure of delamination water based on the principle of communicating vessels, belonging to the field of delamination water hazard prevention and control. It solves the problems of asynchronous water filling and difficulty in exhausting gas from the delamination and hydraulic cavities during the filling process. The invention mainly consists of a delamination cavity, a hydraulic cavity, a screw-piston pressurization device, a delamination cavity exhaust pipe, a hydraulic cavity exhaust pipe, a dual-cavity connecting pipe, a rotatable platform, and a base. Before filling, the delamination cavity and hydraulic cavity are erected on the rotatable platform, with the delamination cavity exhaust pipe and hydraulic cavity exhaust pipe above and the dual-cavity connecting pipe below, thus forming a communicating vessel between the delamination cavity, the dual-cavity connecting pipe, and the hydraulic cavity. During water filling, based on the principle of communicating vessels, the delamination cavity and hydraulic cavity can be simultaneously filled and vented. After filling, the hydraulic cavity is pressurized by the screw-piston pressurization device to generate and monitor superstatic water pressure, providing a feasible technical solution for the synchronous filling and venting of the delamination and hydraulic cavities and the pressurization of the hydraulic cavity.
