Directly-buried hot water pipe network water drainage device

The invention provides a directly-buried hot water pipe network water drainage device which comprises a directly-buried water return pipe and a directly-buried water supply pipe. The directly-buried water return pipe is connected with a water return, drainage and storage pipe through a water return and drainage pipe, and the upper portion of the water return, drainage and storage pipe is connectedwith a water return and drainage well chamber through a first flange. The directly-buried water supply pipe is connected with a water supply, drainage and storage pipe through a water supply and drainage pipe. The water supply and drainage pipe is connected with a water supply and drainage chamber through a second flange. The investment of the water drainage device can be reduced effectively, theoccupied area is small, the construction period is short, operation is convenient, and safety is higher. 本发明提供了一种直埋热水管网泄水装置，包括直埋回水管和直埋供水管，所述直埋回水管通过回水泄水管连接回水泄水存储管，所述回水泄水存储管上方通过第一法兰连接回水泄水井室，直埋供水管通过供水泄水管连接供水泄水存储管，所述供水泄水管通过第二法兰连接
