Description
Technical field
The utility model relates to water conservancy soil property dam leakage Detection Techniques.
Background technology
Most soil property dykes and dams in China's hydraulic engineering build up the fifties in last century to the seventies, be limited to economic technology condition at that time, there is the disease dangerous situation in the dykes and dams filling body, quality can not satisfy existing relevant specification requirement.Though most dykes and dams have obtained the reinforcement processing in recent years, make it to satisfy the safe operation requirement, but can not guarantee its permanent anosis nothing by inches, especially during flood control, the equipment of a kind of energy of needs quick detection dam leakage is measured dam leakage passage and is seemed very necessary.
The dam leakage quick detection mainly contains physical detecting instrument and relevant art such as dc resistivity, self-potential method, induced polarization method, transient electromagnetic method, frequency domain electromagnetic methods, earthquake radar, elastic wave detection, radioactivity prospecting and flow field method detection at present, above-mentioned instrument detection of a target precision is relatively poor relatively, and practical application acquires a certain degree of difficulty.
Summary of the invention
The utility model provides a kind of soil property dam leakage cone penetrometer, and the utility model has solved existing soil property dam leakage detection instrument and existed detection of a target precision relatively poor relatively, the problem that practical application acquires a certain degree of difficulty.
For addressing the above problem, the utility model adopts following technical scheme: comprise the awl spy machine B and the receiver C that are arranged on the ground, and insert underground awl feeler lever and probe A, described awl feeler lever and probe A are made of awl feeler lever 2, insulator 3, four-way probe 4 and conehead 5, awl feeler lever 2 upper ends connect awl spy machine B, awl feeler lever 2 lower ends are connected with conehead 5, and conehead 5 lower ends are horn structure; Four-ways probe 4 is installed in the middle of the awl feeler lever 2, insulator 3 is arranged up and down at four-way probe 4; Lead 1 is connected between four-way probe 4 and the receiver C.
Advantage of the present utility model has: soil property dam leakage cone penetrometer is with awl spy means, based on the TDR technology, by moisture transducer with the emission of high frequency waves with measure and be transferred to receiver with voltage signal, can accurately express the water cut of place, the insertion point soil body, by soil body absolute water content or the comparative analysis of multiple spot water cut, determine the earth and rockfill dam leak path.Have easy, quick, accurately verify the characteristics of earth and rockfill dam leak path, this technology has the potentiality of applying in the inhomogeneous soil body type application of part soil property, meet dam leakage defective characteristics, significant to native bank of stone dam flood control and reinforcement.

Symbol description among the figure: awl feeler lever and probe A, awl are visited machine B, receiver C, lead 1, awl feeler lever 2, insulator 3, four-way probe 4, conehead 5.
Embodiment
Shown in Fig. 1-2, soil property dam leakage cone penetrometer, comprise the awl spy machine B and the receiver C that are arranged on the ground, and insert underground awl feeler lever and probe A, it is characterized in that described awl feeler lever and probe A are made of awl feeler lever 2, insulator 3, four-way probe 4 and conehead 5, awl feeler lever 2 upper ends connect awl spy machine B, awl feeler lever 2 lower ends are connected with conehead 5, and conehead 5 lower ends are horn structure; Four-ways probe 4 is installed in the middle of the awl feeler lever 2, insulator 3 is arranged up and down at four-way probe 4; Lead 1 is connected between four-way probe 4 and the receiver C.
The utility model utilization awl spy machine will be popped one's head in from the downward injection levee body of dykes and dams Surface Vertical, probe will fill native electromagnetic transmission speed along the journey dykes and dams and be transferred to receiving terminal by lead, and the data that terminal receiver will be transmitted can be construed to water cut at 0.5s and show.Dykes and dams fill soil because of the water cut difference, and its electromagnetic wave transport properties is also different, and water cut is higher, and its conduction of velocity is faster, and vice versa.Water cut is greater than 100% in dykes and dams, and apparently higher than top or bottom soil body water cut, can assert that then there is leak path in this point, thereby reach fast measuring dam leakage position.
The roughly target that soil property dam leakage cone penetrometer will detect based on above-mentioned detection instrument and accurately locating is the in-depth or the accurate support equipment of physical detecting technology.Soil property dam leakage cone penetrometer is to transfer signals to receiver by the time domain reflection sense device, thereby reaches the purpose of obtaining dykes and dams soil body water cut.
It should be noted that at last: obviously, the foregoing description only is for the utility model example clearly is described, and is not the qualification to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among the protection domain of the present utility model.
