Abstract
The invention discloses a single-hole geological exploration system. The single-hole geological exploration system comprises a notebook computer, wherein the notebook computer is connected to a main control box through an optical fiber; a directional transmitting antenna and a directional receiving antenna are mounted in a drill rod at a certain interval; the optical fiber led out of the main control box bypasses a winch and is connected to the directional transmitting antenna and the directional receiving antenna; a drilling rig is arranged on one side of the drill rod and controls the directional transmitting antenna and the directional receiving antenna to move in a hole through the drill rod; the drill rod is connected with a drill bit; an electromagnetic wave is transmitted through the transmitting antenna; the directional receiving antenna in a drill hole receives the electromagnetic wave; measurement is carried out once at an interval of 0.5 m to form a profile, a target body is identified according to the travel time, amplitude and phase characteristics of a reflected wave of an abnormal body, and the position, the characteristic and the geometrical shape of the target body are determined, so that acquired signals and data can be more accurate and richer, and the single-hole geological exploration system has the characteristic of high resolution imaging.
Description
Technical field
The present invention relates to geological exploration technical field, particularly a kind of system of single hole detection geology.
Background technology
Geological radar is widely applied at engineering field with its high resolving power and high-level efficiency.According to different working methods, geological radar is divided into surface geology radar and borehole geologic radar.Surface geology radar limits by investigation depth, is unsuitable for carrying out deep detection.Borehole geologic radar directly enters underground deep by holing, and has again the advantage that geological radar resolution is high, is unique feasible and effective detection means in the high-resolution situation of deep problems mandate.External existing maximum probe reaches the borehole geologic radar of 2000 meters, is mainly used in crack detection, detecting caves, ore prospecting, tectonic structure charting and subterranean water enquire etc.Domestic also relatively backward in this respect, there is no high efficiency shaped article.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the invention is to the system proposing a kind of single hole detection geology, the signal of collection and data can be made more accurate, abundant, there is the feature of high-resolution imaging.
To achieve these goals, the technical solution used in the present invention is:
A kind of system of single hole detection geology, comprise notebook 1, notebook 1 is connected to Main Control Tank 3 by optical fiber 2, directional transmitting antenna 6, directional receiving antenna 7 load drilling rod 8 at regular intervals, winch 4 walked around by the optical fiber 2 that Main Control Tank 3 is drawn, and be connected to directional transmitting antenna 6, directional receiving antenna 7, the side of drilling rod 8 is provided with rig 5, rig 5 controls directional transmitting antenna 6 by drilling rod 8 and directional receiving antenna 7 moves in hole, and drilling rod 8 is connected with drill bit 9.
The centre frequency of described directional transmitting antenna 6 is 60 hertz, and sample frequency is at 450-600 hertz.
Because the present invention adopts single hole geology detecting, can be suitable for carrying out deep detection, make collection signal and data more accurately with abundant, can realize high-resolution imaging, the scope of application is wide.
Accompanying drawing explanation
Accompanying drawing is structural principle schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
See accompanying drawing, a kind of system of single hole detection geology, comprise notebook 1, be used for storing and display image, notebook 1 is connected to Main Control Tank 3 by optical fiber 2, directional transmitting antenna 6, directional receiving antenna 7 load drilling rod 8 at regular intervals, winch 4 walked around by the optical fiber 2 that Main Control Tank 3 is drawn, be connected to directional transmitting antenna 6, directional receiving antenna 7, the side of drilling rod 8 is provided with rig 5, rig 5 controls directional transmitting antenna 6 by drilling rod 8 and directional receiving antenna 7 moves in hole, and drilling rod 8 is connected with drill bit 9.The centre frequency of directional transmitting antenna 6 is 60 hertz, and sample frequency is at 450-600 hertz, and optical fiber 2 is used for transmitting the signal of triggering and the data of collection.
Principle of work of the present invention is:
By emitting antenna 6 emitting electromagnetic wave, directional receiving antenna 7 in boring receives electromagnetic wave, measures once, form a section every 0.5 meter, according to the walking of anomalous body reflection wave time, amplitude and phase characteristic identify objective body, distinguishes its position, characteristic and geometric shape.
