Connect, so that water pump 1, floating-ball level switch 2 and power supply 6, which are formed, can cut-off earth-return, so that the more easily connection of control loop
With disconnection.After formation can cut-off earth-return, master switch 8 is closed.
Referring to Fig. 7, in one embodiment of the invention, the process that water pump is put to the bottom of drainpipe can be wrapped
Include：
Step S710, lifting rope is installed on water pump.
Step S720, the switching line of floating-ball level switch is fixed on lifting rope.
Specifically, the switching line 10 of floating-ball level switch 2 is fixed on lifting rope 9 using buckle, the length of switching line 10
Degree can be reserved according to discharge level control range.
Step S730, water pump is hung to the bottom of drainpipe.
Step S740, lifting rope is fixed on to the well head of dewatering well.
In the present embodiment, the length of the switching line of the floating-ball level switch by reserving certain length, it is possible to achieve to row
The control of water level scope, and then realize the function of automatic precipitation in the range of certain height of water level in dewatering well.
Referring to Fig. 8, Fig. 8 is the another stream of the construction method of the automatic base pit dewatering of water level control provided in an embodiment of the present invention
Cheng Tu.As illustrated, this method comprises the following steps：
Step S810, water pump and floating-ball level switch are connected.
Step S820, water pump is put to the bottom of drainpipe, also, floating-ball level switch is placed in what construction in advance was completed
In dewatering well, wherein, drainpipe is located in dewatering well.
Step S830, the water pump after series connection and floating-ball level switch are connected with power supply, so that water pump, Floating Ball Liquid Level are opened
Close and power supply forms loop.
Step S840, after the completion for the treatment of precipitation work, water pump and floating-ball level switch are removed.
Specifically, when it is implemented, according to different geological conditions, 6~10 days startup water pumps 1 before excavation of foundation pit, directly
To after precipitation work completion and backfilling to foundation ditch, water pump 1 is removed.
In the present embodiment, after the completion for the treatment of precipitation work, water pump and floating-ball level switch are removed, to be reused,
Resource is saved.
To sum up, it can be seen that in the present embodiment, pass through the water pump and floating-ball level switch of series connection, it is possible to achieve work as precipitation
Water pump is closed when water level in well is less than turn on pump limit for height water level, and when water level rises to turn on pump limit for height water level, water pump is opened, and works as water level
Water pump is closed when being down to termination of pumping limit for height water level, and then realizes and precipitation is automatically controlled, and avoids artificial level monitoring and easily occurs
When water level is higher in well not timely turn on pump draining the problem of, so as to improve precipitation efficiency；It it also avoid when water is drained in well not
The problem of pump causes draining pump idle running scaling loss is closed in time, so as to save electric power resource；Simultaneously as it can realize to precipitation
Automatically control, decrease certain artificial input.
Obviously, those skilled in the art can carry out the essence of various changes and modification without departing from the present invention to the present invention
God and scope.So, if these modifications and variations of the present invention belong to the scope of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to comprising including these changes and modification.
