Abstract
A geological drilling inclination measuring tool comprises a steel wire rope and a heavy hammer, and is characterized by further comprising a measuring tube capable of being placed in a measured hole, the bottom of the measuring tube is sealed, a bulb is arranged above the heavy hammer, a wire is attached to the steel wire rope connected with the heavy hammer, one end of the wire is connected with the bulb, and the other end of the wire is connected with a power supply. The utility model discloses owing to adopt the survey pipe of rule to arrange the drilling in, can guarantee that the measurement accuracy error is below 1%, its simple structure, the low price.
Description
The utility model relates to a kind of measuring technique, particularly a kind of geotechnical boring deviational survey instrument.
The seepage dangerous section occurs at dam, dyke etc. and need adopt the high pressure jet grouting method to remove the danger when controlling with Louing, need hole on the dangerous section, the distance between each hole is determined according to anti-pierced wall and geological condition, carries out jet grouting in the hole, formation cement concrete cut-pff wall.In order to ensure the cut-pff wall quality, need natural measurement of tilt is carried out in boring.Use at present a kind of tiltmeter, wire rope rope one weight is put in the boring, is provided with magnetic sheet probe in the weight, by the orientation measurement to magnetic sheet, measures the gradient of boring, and this instrument costs an arm and a leg, but trueness error only about 1%.
The purpose of this utility model provides a kind of simple in structure, and is cheap, and the higher geotechnical boring deviational survey instrument of measuring accuracy.
Task of the present utility model is to realize like this, it includes wire rope and weight, it is characterized in that: also have a survey pipe that can place in the measured hole, survey the pipe base seal, the top of weight is provided with bulb, with on the wire rope that weight links to each other with lead, an end of lead connects bulb, the other end connects power supply.
The utility model can guarantee the measuring accuracy error below 1% owing to adopt the survey pipe of rule to place in the boring, and it is simple in structure, and is cheap.
Fig. 1 is a structural representation of the present utility model.
Drawing explanation: 1. survey pipe 2. weights 3. bulbs 4. wire rope 5. leads
In conjunction with above accompanying drawing the utility model is elaborated.This geotechnical boring deviational survey instrument includes wire rope 4 and weight 2, also has a survey pipe 1 that can place in the measured hole, survey the base seal of pipe 1, wire rope 4 is arranged in the pipe, the end of wire rope 4 is a weight 2, its top is provided with bulb 3, and lead 5 is attached to being connected with bulb 3 on the wire rope 4, and the other end of lead connects power supply.
The measuring method of this survey instrument is: select a metal tube that matches with tested boring aperture to insert in the boring, the length of surveying pipe 1 is generally 5～20 meters, the weight 2 that is provided with bulb 3 is put down in pore slowly from the mouth of pipe, when the weight stationary state and when surveying pipe 1 and contact, measure the length that enters wire rope 4 in the pore and the length of weight 2, establishing this length is l, pore diameter is D, then D/l=Sin γ can draw the angle of inclination of boring, thus can determine hole whether qualified.
