The invention discloses a pressure self-adaptive continuous drainer for gas conveying pipelines. A steam inlet pipe and a steam drainage pipe are installed on the side wall of an auxiliary cylinder body with an upper end plate and a lower end plate, and a sewage discharge pipe is arranged on the lower end wall of the main cylinder body. The wall of the main cylinder is connected with a bracket guide pipe, and the water outlet horizontal pipe passes through the bracket block and extends into the inner cavity of the main cylinder, and then connects with the drainage standpipe. Between them, the transition plate is fixedly connected to the lower side of the lower end plate of the buoy, and the guide rod at the center of the upper end plate of the buoy is in the upper guide sleeve at the center of the upper cover. The water inlet horizontal pipe is installed on the lower end side wall of the main cylinder, the lower end of the water inlet vertical pipe is connected with the water inlet horizontal pipe, and the upper end of the water inlet vertical pipe is connected with the gas delivery main pipe through the water inlet end flange. This drainer can automatically adapt to the pressure in the gas delivery pipeline, does not need to replenish water, and is easy to maintain.

The invention discloses a foundation treatment method of full-automatic variable-frequency vacuum prepressing combined electroosmosis. The foundation treatment method comprises the following steps of(1) establishing a standard model, and determining the optimal drainage speed and the minimum electroosmosis voltage according to the standard model; (2) setting N-grade vacuum degrees, wherein the N-grade vacuum degrees are increased step by step at arithmetic progression; determining the maximum electroosmosis voltage, and setting M-grade electroosmosis voltage values, wherein the M-grade electroosmosis voltage values are increased step by step at arithmetic progression; and (3) applying the N-grade vacuum degrees step by step, applying the M-grade electroosmosis voltage values step by stepuntil the electroosmosis voltage reaches the maximum if the drainage speed is less than the optimal drainage speed, and then applying the next grade of vacuum degree, wherein when the vacuum degree reaches the maximum, the foundation treatment is completed. According to the foundation treatment method, the vacuum degrees and the electroosmosis voltage values are applied step by step, so that the phenomenon that a drainage board is clogged is effectively reduced, the continuous drainage time is extended, and additionally, the foundation consolidation time is shortened.
