Description

Technical Field

[0001] This utility model relates to the field of deep foundation pit construction technology, specifically to a water level switch type deep foundation pit dewatering device. Background Technology

[0002] During deep foundation pit construction, timely removal of accumulated water is crucial for ensuring construction safety and project quality. Water level switch-type deep foundation pit dewatering devices sense the water level within the pit using a water level switch. When the water level reaches a set height, the drainage pump automatically starts to drain the water, achieving automated dewatering and finding widespread application in practical engineering. However, existing water level switch-type deep foundation pit dewatering devices have several problems. Firstly, the sensitivity of the water level switch is easily affected by silt and debris within the pit, leading to inaccurate sensing, misjudgments, or missed judgments, thus affecting the dewatering effect. Secondly, after prolonged operation, the drainage pump body and pipes are prone to blockage, making maintenance difficult. Furthermore, although existing devices are equipped with filters, there is a lack of cleaning equipment to prevent filter clogging. In severe weather or complex construction environments, the stability and reliability of the device are low, failing to meet the requirements of efficient and stable operation for dewatering devices in deep foundation pit construction.
