Abstract
The utility model relates to a telescopic paster head for a deep-hole ground stress detector, which is composed of a transmission line, a pusher rod, a pusher, a director and a strain foil, wherein three directors are provided, and each director forms an arc shape in 120 DEG, thus forming the mode of a drill bit used in a drill press, the top of the sheet forms a round hole shape and the middle of each sheet is in adhesive joint with the strain foil. When stretched, the sheet can contact closely with the wall of the holes of the ground stress detector in order to make the strain foil contact firmly to the wall of the holes; when contracted, the sheet can drop smoothly and directly to the bottom of the holes. The utility model has the advantages of flexible and convenient use, reasonable design, simple structure, reliable work and easy use, and also has the advantage that the detected data are reliable and correct, which can reflect the variation state of the three dimensional stress of the deep-hole batholithic ground, and the detected data can be used as the important design consideration of the big-scale work.
Description
Technical field
The utility model belongs to the improvement of the earth stress detection device with paster, exactly, it is to keep under the constant situation of original terrestrial stress pick-up unit and detection method thereof, replacing a kind of telescopic placement head that is used for deep hole the earth stress detection device of inclusion formula placement head structure with telescopic placement head structure.
Background technology
At present, being used for deep hole batholith the earth three-dimensional strainometer stress detection device and detection method thereof has multiple.But their equal X at first settle foil gauge by placement head at deep hole wall different parts, and promptly strain gauge is gathered raw data, and feeding detection apparatus is handled.Foil gauge contacts tightness with hole wall, directly has influence on the accuracy of image data.And these duty placement heads commonly used now that all depend on placement head are the inclusion formula, the cavity round end, and its head size detects Kong Erding according to terrestrial stress, and obviously foil gauge contacts with hole wall and can not reach ideal effect, causes detected data deficiency authenticity.
Summary of the invention
What the purpose of this utility model just designed and produced in the deficiency that overcomes prior art is keeping under the constant situation of original terrestrial stress pick-up unit and detection method thereof, with a kind of telescopic placement head that is used for deep hole the earth Stress Control device of telescopic placement head structure replacement inclusion formula placement head structure.
The utility model structurally is made of 5 parts such as transmission line catch bar, pusher, guides and foil gauges.It is characterized in that constituting catch bar → pusher → guides from top to bottom successively is connected each other.Described guides has 3, and every is 120 ° of arc shapes, constitutes drilling machine drill bit pattern, and the top presents circular poroid, and every centre position is mutually bonding with foil gauge.During extension, detect the hole hole wall with terrestrial stress and closely be connected mutually, during contraction, at the bottom of the deep hole hole that can directly fall smoothly.Described pusher lower end directly closely bonds mutually with guides top circular hole.Transmission line places catch bar, straight-through ground, top related system.
The utility model can uphold and shrink owing to its guides, so very flexible during use, image data is true, accurate, reliable.The variable condition that can truly reflect deep hole batholith the earth three-dimensional stress, it detects the significant design foundation that data can be used as heavy construction.Have reasonable in design, simple in structure, reliable operation, characteristics such as easy to use.
Description of drawings
Fig. 1 is the utility model configuration state synoptic diagram.Wherein, the 1st, transmission line, the 2nd, catch bar, the 3rd, pusher, the 4th, guides, the 5th, foil gauge.In addition, 6 is glue chamber among the figure, and 7 is contact pilotage, and 8 is erector under the hole, and 9 is deep hole, and 10 is terrestrial stress pick-up unit cabin, and 11 is that big terrestrial stress detects the hole.
Specific embodiments
Fig. 1 also is the utility model most preferred embodiment.Wherein catch bar, pusher and guides are self-made components, and transmission line and foil gauge are general part.During implementation, measurement and positioning measuring point planimetric position at first, and to bore an aperture be the degree of depth of the macropore of 130mm until predetermined point, and in the macropore center, boring an aperture again is 36mm, length is the detection segment aperture of 500mm.Then, the telescopic placement head, pusher, the pick-up unit that use erecting device under the hole will be stained with foil gauge are implanted the relevant position in the detection segment aperture, stretch out placement head, foil gauge is closely bonded mutually with hole wall, last injecting glue automatically, foil gauge is fixed on the hole wall, takes out at last that erector just becomes under the hole.
Claims (1)
1, a kind of telescopic placement head that is used for deep hole the earth stress detection device, by transmission line (1), pusher (3), guides (4) and foil gauge (5) constitute, it is characterized in that: described guides (4) has 3, every is 120 ° of arc shapes, constitutes drilling machine drill bit pattern, rounded hole, top, every centre position is mutually bonding with foil gauge (5), detects the hole hole wall with terrestrial stress during extension and closely bonds mutually.
