Description
Technical field
This utility model is related to a kind of base pit dewatering Well Water Level automatic controlling device, belongs to building engineering field.
Background technology
With the development of Urbanization in China, the utilization rate of the underground space also more and more higher, the deep-foundation pit engineering being related to
Also more and more, deep foundation pit support frequently refers to the problem of groundwater treatment.Conventional pattern foundation pit supporting structure groundwater treatment mode
For dewatering well well casing precipitation, but each dewatering well is independent each other, needs the operation of manual measurement level of ground water and control dewatering well,
And the pump-out of the water pump being placed on inside dewatering well is uncontrollable, regional area drawdown is often led to larger.This is not only
Groundwater resources are wasted, and causes surrounding ground and settlement of building excessive so that dangerous situation easily occurs in foundation ditch.Meanwhile,
Existing well casing precipitation scheme efficiency is low, waste groundwater resources and affect periphery structure (building) to build the use safety of thing, causes
Valency increases or construction delay.

Device, the water pressure sensor are connected with control device by the second cable.
Used as improvement, the water plug is identical with the quantity of level measurement device.
This utility model additionally provides a kind of method for controlling multiple base pit dewatering Well Water Levels of utilization the said equipment, including
Following steps：
(1), after precipitation well construction is finished, a variable frequency pump and a water pressure sensor are constituted one group and are positioned over drop
In well, the variable frequency pump and water pressure sensor of different groups are positioned in different precipitation well；Control device obtains water pressure and passes
The depth information of sensor, controls each water pressure sensor and is located at same absolute altitude in dewatering well；
(2) variable frequency pump operational factor, water pressure sensor operational factor and design water level ginseng is input in control device
Number；The control module can show the pump-out (by motor operation power conversion in water pump) of each variable frequency pump, each precipitation
