Abstract
The utility model relates to a ground-coupled geophone string including a transmission cable and at least two geophone units. Each of the geophone units includes at least four sound wave geophones. The sound wave geophones are fixed on the surface of the transmission cable uniformly in a circumferential direction and are used for receiving ground converted waves of seismic waves. According to the utility model, the sound wave geophones are installed in all directions of the transmission cable, so that a fact that the sound wave geophone in at least one side can be coupled with the ground effectively is guaranteed. Required signals are collected through a towing method and the geophones do not need to be inserted into earth surface. The operation and simple and quick, the detection efficiency is high and the earth surface is not damaged.
Description
Technical field
The utility model relates to a kind of the ground coupling string, is applied to geology and engineering exploration, urban road hidden danger and the field such as detects.
Background technology
Traditional seismoreceiver is to realize reception to seismic event by wave detector being inserted or sticks on ground, and this method complicated operation and destructible road surface are difficult to use at urban ground.
For overcoming this shortcoming, another method has been proposed in the prior art, namely be sawed-off the tail cone of wave detector, then wave detector after arranging, the road surface is fixed with mud, tread.This method has caused its detection efficiency not high because its installation process is complicated.
And when carrying out the urban pavement detection, in order not affect traffic, must improve detection efficiency, can not lay one by one wave detector.Therefore, the seismoreceiver in these two kinds of methods all is not suitable for the urban pavement detection.
The utility model content
Technical problem to be solved in the utility model provides a kind of the ground coupling string, is used for solving the geophone coupling problem that urban pavement detects.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of the ground coupling string, comprise a transmission lines cable and at least two pick-up unit, and described each pick-up unit includes at least four aural detectors; Described each aural detector along the circumferential direction is fixed on the surface of described transmission cable equably, is used for receiving the ground converted wave of seismic event.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described aural detector adopts insertion or welding manner to be fixed on the surface of described transmission cable.
Further, be provided with the spacing that equates between described each pick-up unit and the adjacent pick-up unit.
Further, the signal that receives of described each pick-up unit is the stack of the signal that receives of they all aural detectors that comprise.
Further, the skin of described pick-up unit is provided with containment vessel.
The beneficial effects of the utility model are: a kind of the ground coupling string described in the utility model all is equipped with aural detector in all directions of transmission cable, guaranteed always to have the aural detector of one side effectively to be coupled with ground, mode with towing cable collects needed signal, will not be inserted under the earth's surface by wave detector, simple and quick, detection efficiency is high, and can not destroy the earth's surface.Simultaneously, this string is provided with containment vessel to pick-up unit, can also be applicable to the several scenes such as sleet, has enlarged range of application.
Description of drawings
Fig. 1 is the structural representation of string described in the utility model;
Fig. 2 is the application synoptic diagram of string among the utility model embodiment.
In the accompanying drawing, the list of parts of each label representative is as follows:
1, transmission cable, 2, pick-up unit, 3, aural detector, 4, ground, 5, collector.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
As shown in Figure 1, the described a kind of the ground coupling string of present embodiment comprises a transmission lines cable 1 and at least two pick-up unit 2, and described each pick-up unit 2 includes at least four aural detectors 3; Described each aural detector 3 along the circumferential direction is fixed on the surface of described transmission cable 1 equably, is used for receiving the ground converted wave of seismic event.When mounted, according to actual needs, determine the number of pick-up unit 2 and the spacing of adjacent pick-up unit 2, guarantee that the spacing between the adjacent pick-up unit 2 equates.In the present embodiment, string is totally ten six pick-up unit 2, and each pick-up unit 2 respectively has four aural detectors 3, described four aural detectors 3 are installed in respectively on the four direction of transmission cable, guarantee always to have the aural detector 3 of one side effectively to be coupled with ground, collected needed signal.
In addition, described aural detector 3 adopts and inserts or the surface of the fixing described transmission cable 1 of welding manner, and the signal that receives of described each pick-up unit 2 is the stack of the signal that receives of they all aural detectors 3 that comprise.
Simultaneously, be the protection string, the skin of described pick-up unit 2 also is provided with containment vessel.
As shown in Figure 2, the operating process of the described string of present embodiment in urban pavement detects is: string 4 is launched on ground, and be connected with collector 5.During work, knock with hammer on ground, produce seismic event, seismic event produces transformed wave on the earth's surface, and string receives transformed wave, and the transformed wave signal that receives is transported to collector 5, collector 5 is transferred to computer to the signal that is recorded to, computer carries out analyzing and processing to signal again, draws whether defectiveness of road, finishes the testing of whole urban pavement.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
