Four-way water drainage device for landfill gas collection pipeline

The invention relates to a four-way water drainage device for a landfill gas collection pipeline. A gas exhaust pipeline is connected with a water collection silo through a four-way joint; a water drainage pipe and a high-pressure gas inlet pipe are arranged in the water collection silo; and a lower port of the high-pressure gas inlet pipe is bent to form a U-shaped gas outlet and is inserted into a lower port of the water drainage pipe. The construction process is simple and mature; the environment adaptability is high; seepage liquid is convenient to drain; the maintenance cost is low; water gathered in the pipeline is reduced; and the halt time is shortened. The four-way water drainage device is suitable for a large-range landfill field and can automatically drain water without the help of workers, so that human resources are saved, and maintenance cost is reduced. By adopting the four-way joint, the gas exhaust pipe and the water collection silo are fixed together without mutual interference; and under the condition that the gas exhaust pipe is unblocked, condensed water can be collected and drained conveniently.
