On the other hand cheating current depth can be worked as during the entire process of base pit dewatering operation according to underwater fluid change in real time
Preceding foundation depth.In conclusion underground water level measuring device described in the utility model, structure simplifies, and effectively improves measurement
While precision, it is not necessarily to other equipment or operation, so that it may show that current foundation pit is deep according to the variation of underwater water level in real time
Degree, and measurement cost is greatly reduced, improve measurement efficiency.
Detailed description of the invention
Fig. 1 is schematic diagram, shows the knot of underground water level measuring device described in one embodiment of the utility model
Structure.
Specific embodiment
The embodiment of underground water level measuring device described in the utility model described below with reference to the accompanying drawings.This field

Enter underground, weight 2 sinks to the water surface hereinafter, under the traction of weight 2, and measurement rope 1 is straightened, when flotation gear 3 is suspended in the water surface
When upper, weight 2 stops declining and hovering below the water surface under the buoyancy of flotation gear, then can be according on measurement rope
Reading obtain the depth of current foundation pit.Then, after base pit dewatering operation starts, pumping for water pump is opened, underground water level declines,
The traction that weight 2 underwater at this time loses flotation gear continues to sink below the water surface, until flotation gear 3 hovers over new water
On position, then under the action of weight 2, measurement rope 1 is straightened again, is worked as at this time again according to the reading on measurement rope 1
Preceding foundation pit underground depth.
As described above with practice it is found that underground water level measuring device described in the utility model, is filled by transmission
It sets and measurement rope is poured into underground above well head, then measurement rope is straightened by the weight of measurement rope end setting, measure
Floating material is set close to the position of weight on rope, then after measurement rope protrudes into underground, weight is sunk to below the water surface, and flotation gear
It is suspended on the water surface；When base pit dewatering operation starts, down-hole water pump work, underground water level decline measures under weight traction
Rope further declines to underground, until floating material touches the water surface and is suspended in above the water surface；In this way, in base pit dewatering operation
In the process, the data of current foundation depth can be obtained according to the variation of the underground water surface in real time, compared to the prior art in general
Measurement rope is promoted after declining repeatedly again and in such a way that watermark location estimates foundation depth, mine water described in the utility model
On the one hand suspended matter is arranged in level measuring arrangement, can accurately obtain base according to the length of the measurement rope above suspended matter to well head
On the other hand cheating current depth can be worked as during the entire process of base pit dewatering operation according to underwater fluid change in real time
Preceding foundation depth.In conclusion underground water level measuring device described in the utility model, structure simplifies, and effectively improves measurement
While precision, it is not necessarily to other equipment or operation, so that it may show that current foundation pit is deep according to the variation of underwater water level in real time
Degree, and measurement cost is greatly reduced, improve measurement efficiency.
