| titleOfInvention | A kind of test device and method for gram mud effect sealing barrier effect and gas purification treatment |
| abstract | The invention discloses a test device and method for gram-mud sealing and barrier effect and gas purification treatment. The device comprises a gas generating module, a sealing test module, a gas detection module, an automatic timing module and a purification processing module; the sealing test module comprises a sealed hollow cylinder, in which a test chamber is arranged; the upper end of the test chamber is connected to the gas Generation module; the gas detection module is a U-shaped tube containing conductivity detection liquid, the top is sealed, one end of the tube body is connected to the bottom end of the test tank, and the other end is connected to the purification processing module; the automatic timing module is arranged at the U-shaped tube outlet side. The test device and method can study the failure phenomenon and failure mechanism of the gram mud effect layer under different test conditions, quantitatively determine the optimal mix ratio and thickness critical threshold of the gram mud effect used in construction, so as to guide the on-site shield construction, and can The treatment of residual exhaust gas greatly reduces the harm to the test personnel and the surrounding environment. |
