Description
Technical field
A kind of more elevation seepage flow pressure testers of dam are the utility model is related to, belong to hydraulic engineering technical field.
Background technology
China's dam is large number of, its whether safe security of the lives and property for being related to the downstream people, and influences big
The important evidence of dam safety analysis --- can saturation and Uplift data reliable and stable in dam body measurement and in real time
Grasp seem very urgent.It is existing according to hydraulic engineering《Concrete dam safety monitoring technology specification》SL601-2013 and
《Safety monitoring of earth-rockfill dams technical specification》SL551-2012 regulation：In order to monitor the safe operation of concrete dam, earth and rockfill dam, level
Porous flow pattern facility all should be set in 3 grades and 4 grades, dam of 5 grades of heights of dam more than more than 30m, to observe and to grasp at any time
The pore pressure of dam seepage line and the dam foundation.Traditional method is to be beaten on the cross section of dam every a segment distance in practice
The well of one bore very little, pressure-measuring pipe is inside set again, then measures the hydraulic pressure in pressure-measuring pipe and seepage pressure to obtain reality
Data are surveyed, some larger dam bodys can be provided with observation gallery, and foregoing pressure-measuring pipe is arranged in observation gallery and supplies technical staff
Observation.
Pressure tester is the important component of porous flow pattern system, traditional pressure tester by pressure-measuring pipe, be connected to survey
Three-way pipe, osmometer, pressure gauge in pressure pipe and the end socket for closure etc. form.Pressure-measuring pipe is by real pipe, permeable floral tube
Formed with sediment tube.With the development of digital information technique, nowadays pressure tester uses osmometer more.In general one
One osmometer of placement in pressure-measuring pipe, according to the different to react the osmotic pressure of correspondence position of the depth of burying, work as osmometer
After failure, the collection of the Monitoring Data of the pressure-measuring pipe will be affected, so as to have influence on the normal operation of monitoring system.This
Outside, due to only installing an osmometer in pressure-measuring pipe, survey whether data accurately typically can only by virtue of experience judge, lack available
In the data of contrast reference.
The content of the invention
The purpose of this utility model is：The defects of overcoming above-mentioned prior art, propose that one kind can be with accurate judgement osmotic pressure
Meter failure is simultaneously capable of the measurement apparatus of the more elevation seepage pressure values of Measurement of Dam.
In order to solve the above-mentioned technical problem, technical scheme proposed by the present invention is：A kind of more elevation seepage flow pressure measurement dresses of dam
Put, including the pressure-measuring pipe being vertically arranged and the osmometer in pressure-measuring pipe, the pressure-measuring pipe pass through affixed
Water-stop sheet on pressure measurement inside pipe wall is divided into multistage, and every section of pressure-measuring pipe is equipped with floral tube；Pass through between adjacent two sections of pressure-measuring pipes
Thread connection, the water-stop sheet is provided with screwed hole and matches with the screwed hole and be formed with externally threaded water proof ring, each
An osmometer is equipped with section pressure-measuring pipe, and each osmometer is respectively connected with through water proof ring and the data that extend to outside pressure-measuring pipe
Gathering line；It is tightly connected between the data acquisition line and water proof ring by marine glue.
The utility model when in use, in order to measure more elevation seepage pressure values, and causes osmometer in each elevation measured value
Independently of each other, pressure-measuring pipe is separated by multistage by water-stop sheet, so as to be provided with relatively independent compartment in pressure-measuring pipe, so not
Floral tube with current from each section of pressure-measuring pipe of elevation is respectively enterd in different compartments, and the current of different elevations are independent,
The seepage pressure value of more elevations is measured by different osmometers.With an osmometer is disposed in a pressure-measuring pipe in the prior art
Compare, the seepage pressure value that the utility model can measure according to the adjacent osmometer of each osmometer judges whether osmometer goes out
Existing failure, so carry out judging to compare for experience more accurately and reliably by contrasting the data of reference.
In addition, the utility model is cemented together and close through the progress of water proof ring by the data acquisition line of multiple osmometers
Envelope, so as to realize that the selection of osmometer number is free, use is more convenient.
The further improvement of above-mentioned technical proposal is：When passing through thread connection between adjacent two sections of pressure-measuring pipes, top pressure measurement
Pipe is formed with internal thread in connection place, and bottom pressure-measuring pipe is formed with the external screw thread to match with internal thread in connection place.
The further improvement of above-mentioned technical proposal is：The data acquisition line is made of flexible material.It is because described
When water proof ring and water-stop sheet are thread connection, and different elevations needs that installation water proof ring is respectively configured, in interlude
Measurement compartment in data acquisition line distortion necessarily occurs, therefore, to ensure that osmometer keeps vertical after installation, often
The data acquisition line of the osmometer extended at one elevation must be sufficiently flexible, enables osmometer freely sagging, such measurement result
It is more reliable.
The further improvement of above-mentioned technical proposal is：In the junction of adjacent two sections of pressure-measuring pipes, top pressure-measuring pipe is provided with
Link, bottom pressure-measuring pipe are provided with the hook to match.Link and hook are set in connecting sewing surrounding upper-lower section, so as to enter one
Step ensures the stability of connection.
Brief description of the drawings
The utility model is further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the connection diagram of water proof ring and water-stop sheet.
Fig. 3 is the connection diagram of data acquisition line and water proof ring.
Embodiment
Embodiment one
As Figure 1-3, the more elevation seepage flow pressure testers of the dam of the present embodiment, including the pressure-measuring pipe 1 being vertically arranged with
And the osmometer 3 in pressure-measuring pipe 1, pressure-measuring pipe 1 pass through the water-stop sheet 6 being fixed on the inwall of pressure-measuring pipe 1 and divided
Multistage is divided into, every section of pressure-measuring pipe 1 is equipped with floral tube 4, and floral tube 4 is used for UNICOM's external water pressure；Pass through between adjacent two sections of pressure-measuring pipes 1
Thread connection（One section of pressure-measuring pipe is fixed during installation, another section of precession connection）, water-stop sheet 6 be provided with screwed hole and with the spiral shell
Pit matches and is formed with externally threaded water proof ring 5, and an osmometer 3, each osmometer 3 are equipped with each section of pressure-measuring pipe 1
It is respectively connected with through water proof ring 5 and the data acquisition line 2 that extends to outside pressure-measuring pipe 1；Lead between data acquisition line 2 and water proof ring 5
Marine glue 9 is crossed to be tightly connected.As shown in figure 3, centre is pieces of data gathering line 2, it is around fixed marine glue 9, even
When connecing, more single data gathering lines 2 are sealed cementing on water proof ring 5 by marine glue again after can mutually winding.
When in use, the floral tube of current from each section of pressure-measuring pipe of different elevations respectively enters water-stop sheet 6 and separated the present embodiment
Different compartments in, the current of different elevations are independent, the seepage pressure value of more elevations is measured by different osmometers.
Preferably, when passing through thread connection between adjacent two sections of pressure-measuring pipes, top pressure-measuring pipe is formed with internal thread in connection place,
