Description
Technical field
This utility model relates to a kind of Municipal Engineering Construction technology, especially one subway leak detection technology, specifically
Say it is a kind of Metro Deep Excavation water sealing structure seepage defect sonar seepage detector.
Background technology
In the last few years, along with the fast development of urban construction, people also increase dynamics to the exploitation of the underground space,
While especially in Metro Construction, foundation depth and scale increase, the difficulty that foundation pit supporting project is built is the most prominent
Go out, particularly in the transformation project of old town, be faced with in complex geological condition the impact of abundant subsoil water.The impact of subsoil water
The foundation pit supporting construction failure case caused can be found everywhere, and result causes Nearby Structure cracking, tilts, and road gets deeply stuck in, ftractures,
Underground utilities misplace, and even Nearby Structure caves in and casualties, and economic loss is great, this not only schedule delays, produce simultaneously
Give birth to bad social influence.
Concealed work under deep basal pit possession, difficulty of construction is big.Owing to artesian water risk factor being lacked full appreciation and lacking
Weary artesian water risk control measure comprehensive, effective, a series of key technical problems relevant to deep-foundation pit engineering seepage flow are still
Annoying us, this is also the main inducing causing many serious accidents, hinder deep-foundation pit engineering green construction and
The sustainable development of project.
After completing currently for water seal for deep foundation pit structure construction, do not have effective method that underground water-stop curtain is executed
Work defect carries out quality testing targetedly and seepage flow management and control, does not more have the technical bid of corresponding foundation pit waterproof curtain quality testing
Standard, particularly foundation ditch artesian water are the most blank with influence research to the destruction of water sealing structure defect.For quality before excavation of foundation pit
The problem of perception of defect, often plays at some game of chance or a follow-up flower huge sum of money carries out reinforcement protection to water sealing structure, does not form prevention and control
Mechanism is to reduce the risk in excavation of foundation pit.Excavation of foundation pit makes the overburden layer of bottom artesian aquifer thinning, arrives bottom foundation ditch
When the residual soil layer of artesian aquifer top board can not balance with the buoyancy of artesian water head, prominent gushing bottom foundation ditch, will be produced.
Owing to prominent gushing is instantaneous generation, it is difficult to take in time to successfully manage measure, easily cause the destructive accident of base pit engineering also
Jeopardize the safety of surrounding enviroment.The piping and seepage caused because of water-stop curtain defect once occurs, by directly jeopardize Environmental security with
Foundation ditch is stable.Therefore, before excavation of foundation pit, accurately detect whether body of wall exists seepage, and take advanced targetedly
Reinforcement measure can effectively evade foundation ditch risk.
And at present detection for water-stop curtain defect is to be observed by precipitation in hole to cheat outer SEA LEVEL VARIATION, it is limited to qualitative to sentence
Disconnected method, cannot quantitatively determine, it would therefore be highly desirable to need new skill for the locus of defect and seepage discharge, percolation flow velocity
Art means determine leak location and character.
Utility model content

One carries out the falling tone of leak detection for the seepage flow detection well burying water sealing structure seam underground receives measuring probe 4；
One for receiving first described sonar to measure probe the 1, second sonar measuring probe the 2, the 3rd sonar to measure probe 3
The sonar signal of measuring probe 4 sonar signal received can be analyzed, calculates, judges and identifies is received with the falling tone
Computer 5.
First described sonar to measure probe the 1, second sonar measuring probe the 2, the 3rd sonar to measure probe 3 and the falling tone are received
Measuring probe 4 is connected with computer 5 by wired or wireless.
First described sonar to measure probe the 1, second sonar measuring probe the 2, the 3rd sonar to measure probe 3 and the falling tone are received
Measuring probe 4 has been also respectively connected with GPS position finder, and the seat information of breakthrough can be sent in computer be used for by GPS position finder
Determine concrete leak location.
The beneficial effects of the utility model:
This utility model solves a difficult problem for Metro Deep Excavation excavation front percolating water detection, and the solution for seepage provides one
Hands data, utilizes device of the present utility model can quickly judge leak location and leakage, thus provides for engineering decision
First-hand data, the advance reinforcement for engineering provides technical guarantee.Advantageously reduce engineering cost.
This utility model simple in construction, easy to install.
Accompanying drawing explanation
Fig. 1 is composition structural representation of the present utility model.
Detailed description of the invention
With embodiment, this utility model is further described below in conjunction with the accompanying drawings.
As shown in Figure 1.
A kind of Metro Deep Excavation water sealing structure seepage defect sonar seepage detector, it includes:
