Abstract
The utility model relates to a dynamic sounding device used for engineering survey. The main problems with prior dynamic sounding method are: hammering the dynamic probing rod on the floor surface causes the probing rod to bend easily, penetration resistance is strong, penetration depth is shadow, so that hard soil and rocks can not be penetrated, and major errors exist in metrical data. The key point of the technical proposal is that an air-powered down-the-hole hammer is directly arranged on an electrical logging dynamic probe; the method of dynamic sounding by hammering floor surface is changed into an in-the-hole hammering method; the diameter of the electrical logging dynamic probe is larger than the diameters of the air-powered in-the-hole hammer and the dynamic probe; the electrical logging dynamic probe is provided with an electric probing device therein. The utility model has the advantages of: (1) great sounding depth, unpliable dynamic probe, less friction resistance, good verticality and fast penetration speed of the dynamic probe hole; (2) the electrical logging dynamic probe capable of precisely and reliably collecting, storing or emiting geological data continuously on real-time basis; (3) wide applicability to the sounding of various rocks.
Description
Technical field
The utility model relates to a kind of dynamic sounding equipment that is used for engineering investigation.
Background technology
At present, the various dynamic sounding methods that engineering investigation adopts, be the weight of certain mass to be risen to certain altitude on ground, free-falling, to move probe squeezes in the soil, test the mechanics index of physics of ground such as bearing capacity of foundation soil, modulus of deformation according to the hammering number of injection certain depth, simple equipments, error is big.
At present, various dynamic sounding methods all are on the face of land feeler lever to be applied the hammering penetrating power, and moving feeler lever rocks, and is flexible, penetration resistance is big, and depth of penetration is little, general depth of penetration 5-20m, can not pass pan soil and rock, can not satisfy highrise building, the requirement of high-speed railway depth of exploration 60-100m.
In the market, it is big not see the feeler inspection degree of depth as yet, and moving probe can real-time continuous be gathered geologic data, the dynamic sounding equipment that accuracy is high again.
Summary of the invention
The purpose of this utility model provides a kind of aeratic hidden hole hammer dynamic sounding equipment, and not only the feeler inspection degree of depth is big, again can real-time continuous gathers the dynamic sounding equipment of geologic data.
The utility model is by the following technical solutions: change current driving force feeler inspection face of land hammering method, be hammering method in the pneumatic down-hole hammer hole, pneumatic down-hole hammer is a pneumatic structure device that can produce percussion, its profile is cylindric, and pneumatic down-hole hammer directly is placed on the moving probe of electrical measurement, and the body of calming the anger that air compressor machine produces is by the sebific duct of supplying gas, through moving feeler lever, the continuous injection of the moving probe of the direct hammering electrical measurement of the body of will calming the anger input pneumatic down-hole hammer, moving feeler lever is not subjected to injection pressure, and is not crooked; Adopt the diameter of the diameter of the moving probe of electrical measurement greater than moving feeler lever and pneumatic down-hole hammer, frictional resistance is little during injection; The moving probe end of electrical measurement is taper shape or hemisphere profile of tooth, and positioned inside has electrometric sensor, and is provided with memory or sender unit, the geologic data of real-time continuous collection can be passed to the feeler inspection recorder.
The beneficial effects of the utility model are: (1) feeler inspection degree of depth is big, and moving feeler lever is not flexible, and frictional resistance is little, and moving inspecting hole verticality is good, and injection speed is fast; (2) but the collection of the moving probe of electrical measurement real-time continuous, storage or emission geologic data are accurately reliable; (3) applied widely, can be used for the feeler inspection of all kinds ground.
