Anti-freezing method and device of water wells in perennial frozen soil
The invention discloses an anti-freezing method and device of water wells in perennial frozen soil. The anti-freezing method includes the step that while a water pump stops running, water level in a water well is decreased to be below the perennial frozen soil by pressure of high-pressure gas. The anti-freezing device comprises a high-pressure gas source (1). The high-pressure gas source (1) is connected with a water pump outflow pipe (5) through a gas supply pipe; the gas supply pipe is provided with a gas supply valve (2). The anti-freezing device further comprises an exhaust valve (3). An inlet of the exhaust valve (3) is communicated with a well-wall pipe (6) through an exhaust pipe. An outlet of the exhaust valve (3) is communicated with atmosphere. The anti-freezing device further comprises a water supply valve (4) arranged behind a gas supply pipe connection on the water pump outflow pipe (5). The anti-freezing method and device is capable of simply and effectively preventing the water wells in the perennial frozen soil from being frozen.
