The present application relates to the field of compressed air energy storage, and particularly relates to a compressed air energy storage underground cavern lining test device with less required filling gas and more stable gas pressure, comprising a support cylinder, which is sleeved with a ring-shaped lining, and a sealed cavity is formed between the side wall of the support cylinder and the elastic sealing layer of the side wall of the ring-shaped lining; and an air inlet is arranged to connect the sealed cavity with the outside. The present application is particularly suitable for use in the compressed air energy storage underground cavern lining test.

This invention relates to an experimental method and apparatus for simulating deep karst collapse induced by overloading of dense building complexes. The apparatus includes: a model test chamber for placing test soil; a karst channel mechanism with karst channels of different sizes distributed throughout; a loading mechanism for simulating the application of loads to dense urban building complexes and soil consolidation; an intelligent display mechanism; an image acquisition mechanism for observing changes in the overlying soil layer and the underlying karst channels during the loading process; a data analysis mechanism; a karst collapse soil collection mechanism for collecting collapsed soil; and a support mechanism for providing reaction forces to balance the applied load. Compared with existing technologies, this invention can provide technical support for studying deep karst collapse induced by static overloading of dense urban building complexes, reveal the mechanism of deep karst collapse under static overloading of dense urban building complexes, determine the critical disaster-causing and destructive conditions of deep urban karst collapse, and provide reference value for the treatment and prevention of deep urban karst collapse.

The application relates to the technical field of battery materials, in particular to a paste charging material compression test device and a test method thereof, which comprises a testing machine support, a sample box mounted on the testing machine support, a compression test box and a protective gas source box, the inside of the sample box is provided with a temperature control room, and the inside of each layer of the separated rooms is provided with an automatic feeding mechanism and a heating plate. The application prevents the external environment from affecting the test results through the settings of the sample box, the temperature control room, the lifting chamber and the compression test box, reduces the influence of the temperature accuracy reduction caused by manual operation through the settings of the multiple separated rooms in the temperature control room, realizes rapid testing of multiple samples, and also facilitates the control test, so that the device has high universality, the settings of the automatic feeding mechanism, the vertical lifting support, the first electric push rod and the second electric push rod do not need manual feeding and discharging, reduce manual intervention and external influence, and further improve the accuracy of the test.
