Drainage equipment and method for low-lying position of underground building
The invention relates to the technical field of low-lying accumulated water drainage of underground buildings, and discloses drainage equipment for a low-lying position of an underground building. The drainage equipment comprises a waste water tank (1), a waste water taking pipe (2) arranged in the waste water tank (1), a drainage pipe (3), a drainage solenoid valve (31), a first pipeline (4), a vacuum solenoid valve or mini vacuum pump (41), a second pipeline (5), an emptying valve (51) and a first liquid level sensor (6), and the inner side of the waste water tank (1) is provided with a grid (11). The invention further discloses a drainage method for the low-lying position of the underground building. The method comprises the steps that the drainage equipment at the low-lying position of the underground building is connected with a vacuum source, the waste water taking pipe (2) is inserted into the bottommost position of a low-lying foundation pit (8), and when accumulated water in the low-lying foundation pit (8) reaches a set value of a second liquid level sensor (7), the accumulated water is firstly sucked into the waste water tank (1) and then drained to a drainage ditch or waste water well depending on the gravity or a sewage discharge pump. Accordingly, the technical problems that the underground buildings such as subway stations and underground commercial spaces are smaller in local low-lying position, and accumulated water drainage is difficult are solved.
