Embodiment
To make the purpose, technical scheme and advantage of the example of the utility model clearer, below in conjunction with the utility model
Accompanying drawing in example, the technical scheme in the example of the utility model is clearly and completely described, it is clear that described reality
Example is a part of example of the utility model, rather than whole examples.Based on the example in the utility model, the common skill in this area
The every other example that art personnel are obtained under the premise of creative work is not made, belong to the model of the utility model protection
Enclose.
Fig. 1 is the utility model foundation pit pile top sedimentation deformation monitoring device structural representation, as shown in figure 1, this example fills
Put, including：
Be arranged at datum mark liquid storage unit, for measure the pressure measurement cell of fluid pressure in the liquid storage unit,
Data acquisition unit and the breather pipe for UNICOM's ambient atmosphere；
The breather pipe is arranged at the liquid storage unit upper end, and the pressure measurement cell passes through pressing plate and half circular boop and base
The reinforcing bar of hole stake top is fixed, as shown in Figure 2.The liquid storage unit is connected by pipeline with the pressure measurement cell, the pressure
Power measuring unit is connected by cable with the data acquisition unit.
Specifically, pressure measurement cell is fixed on the steel for monitoring pile head settlement with pressing plate and half circular boop in this example
It is set to be settled with pile head settlement on muscle.Liquid storage unit is connected to by water pipe, liquid storage unit is stored up for annular in this example
Flow container, the fluid pressure in fluid reservoir is measured by pressure measurement cell, and pressure value is converted into data signal transmission
To data acquisition unit.
The liquid storage unit of datum mark is arranged at, is not changed with pile head settlement.In this example inside annular fluid reservoir
Liquid is water, and the bottom delivery port of the fluid reservoir is connected by water pipe with pressure measurement cell, and top passage passes through ventilation
Pipe UNICOM ambient atmosphere.The liquid of injection is about full of the 3/4 of fluid reservoir total capacity.In order to find the steaming of liquid in device in time
Heat condition, this example are not limited to this.
The liquid pressure value that pressure measurement cell drop gathers in real time is sent to data acquisition unit, the data acquisition unit,
Server is sent back by wireless communication unit, it is independently-powered that the monitoring device that solar panel is this example can also be configured
System.
Pile head settlement amount is calculated according to real-time liquid pressure value in server.For example, pressure measurement cell is being sent out
The hydraulic pressure P1 of datum mark is measured before raw pile head settlement, pressure measurement cell measures current foundation pit pile top position after pile head settlement occurs
The hydraulic pressure P2 put, server according to formula P1=ρ gh1, P2=ρ gh2, wherein, ρ be the density of water, g represent acceleration of gravity,
Draw the water-head h1 between liquid level and pile head settlement monitoring point present position liquid level in liquid storage unit, in liquid storage unit liquid level and
Water-head h2 between the liquid level of pile head settlement monitoring point present position, because liquid level keeps constant in liquid storage unit, therefore,
Difference between h1 and h2 is the settling amount of pile head settlement monitoring point present position.
Fig. 3 is the utility model foundation pit pile top sedimentation deformation monitoring system schematic diagram, as shown in figure 3, the monitoring of this example
System can complete the pile head settlement monitoring to multiple stake top monitoring points simultaneously, and liquid storage unit is erected at non-pile head settlement region, i.e.,
Position away from pile head settlement monitoring point, is arranged in the pressure measurement cell at the liquid storage unit as datum mark, datum mark
Hydraulic pressure value be used to checking the liquid level of liquid storage unit and whether change, if the liquid level of liquid storage unit is changed, settle
The calculating process of amount needs to consider the variable quantity；Raw material band is tied between three-way connection and liquid delivery tube；Each pile head settlement prison
Pressure measurement cell is arranged on measuring point, the pressure measurement cell integrally settles with pile head settlement monitoring point；The utility model energy
It is enough to realize that pile head settlement variable quantity is changed into variation in water pressure amount carries out automatic data collection；The reasonable erection of each pile head settlement monitoring point
Satisfaction can allow the hydraulic pressure data collected to reflect region pile head settlement situation.
Pressure measurement cell is set to try one's best arranged orthogonal at pile head settlement monitoring point；Slowly water filling, water at liquid storage unit
Stream fills liquid delivery tube by liquid storage unit, and now plug does not block to liquid delivery tube one end, liquid delivery tube
Start draining, after bubble in pipe is with liquid such as current emptying, blocked one end of liquid delivery tube using plug；Each pressure is surveyed
The hydraulic pressure data that amount unit measures send data acquisition unit to via cable, and data acquisition unit will by wireless communication unit
Hydraulic data is sent to server.
The beneficial effects of the utility model are：
1st, existing settlement monitoring equipment hydrostatic level is different from, the utility model is to cause hydraulic pressure to become according to liquid level change
The principle of change, avoid the limitation of the mounting condition suffered by hydrostatic level；
