Abstract

The utility model discloses a new style engineering geological detector, belonging to a measuring instrument which is used for detecting the variable of an electromagnetic field on the earth. The measuring instrument directly gives the lithology curve which denotes the depth of stratum through the processing of a micro-computer according to the measured counter radiation waves with different frequency of the stratum. The placement and the storage of water, coal, salt and metal can be recognized, and the structure of skewness, break, extinguishment, hole of the stratum is ascertained. The measuring instrument is composed of a plate band type capacitive sensor, the amplifier of stratum lithology radiation waves, a converter which is used for the simulation deconvolution processing of stratum lithology signals and the shaping of pulse analog-to-digital and a microcomputer which is used for the automatic processing of signals.

Description

Engineering geological detector
The utility model belongs to the technical field of earth electromagnetism variable surveying instrument, is specially adapted to measure underground lithology situation and stratal configuration.
In the prior art, there was modern age the measurement of utilization solar wind outside ionosphere, to evoke blast, disturbance earth electromagnetic field, in the stratum, inspire the contrary width of cloth ejected wave of different frequency, measure underground lithology situation and stratal configuration, but also only being in a kind of primary status, is to rely on the survey crew ear to listen the tone of contrary width of cloth ejected wave to judge underground lithology situation, therefore, the geological effect that its detection obtains varies with each individual, and is difficult to promote.
The purpose of this utility model is to design the degree of depth---the lithology curve that a kind of novel engineering geology detection instrument can directly provide tested stratum according to the frequency of the contrary width of cloth ejected wave that measures the stratum, is used as the instrument of may visiting of coalfield, the hydrology, metal mineral reserves or as reservoir, the dam foundation, roadbed, abutment, pile ground engineering geologic prospecting instrument.
Enforcement means of the present utility model are simulation deconvolution processing and pulse modulus shaping transducers of a kind of amplifier by strip formula capacitive transducer, the contrary width of cloth ejected wave of formation lithology of design, formation lithology signal and are used for the engineering geology detection instrument that the automatic microcomputer four big parts of handling of signal constitute.
Not the utility model has the advantages that and need dig a well, blow out that only need this engineering geology detection instrument is placed on the ground that needs detecting location, start can be surveyed, and directly provides the degree of depth---the lithology curve, simple, easy to carry; Detectivity is strong, can discern water, coal, salt and metal mineral reserves, also can find out the stratum tiltedly, break, go out, structure such as hole.The maximum probe degree of depth of this detection instrument is 1100 meters, surveys the lithology curve and the drilling data that obtain and contrasts coincidence rate more than 70%, and its accuracy is much higher than conventional electromagnetic prospecting gained result.
