The instrument comprises an in-hole protection ring, wherein the upper part of the in-hole protection ring is provided with a bracket; a vertical positioner consisting of a pendulum bob and a measuring ruler is hung in the center of the bracket; the center of the measuring ruler is positioned in the circle center of the in-hole protection ring; and the bracket is provided with a connecting rod vertical to the bracket. The instrument is easy and convenient to use, and has high measurement reading accuracy and a wide measuring range (an azimuth angle of 0 to 360 degrees and an inclination angle of 0 to 90 degrees); and products of different sizes can be manufactured on site, and the instrument is used for measuring holes with different apertures.
Description
Affiliated technical field
The present invention relates to a kind of engineering survey device, the measurement mechanism especially using in boring, belongs to engineering measuring technology field.
Background technology
At present, the dam in hydraulic engineering is increased in construction, need on gate pier, hole, arrange therein anchor cable, azimuth deviation when boring and error of tilt accuracy requirement are higher, when boring, need carry out synchro measure to it, and conventional electromagnetic teleclinometer cannot use owing to being subject to the impact of reinforcing bar in concrete.
Summary of the invention
For the problems referred to above, the invention provides a kind of hole interior positioning-measuring instrument.
The technical solution adopted for the present invention to solve the technical problems is: hole interior positioning-measuring instrument; comprise protection ring in hole; in hole, protection ring top is provided with support; carriage center is hung with the vertical positioner of pendulum and surveyors' staff formation; the center of circle that is centered close to protection ring in hole of surveyors' staff, support is provided with perpendicular connecting link.
The invention has the beneficial effects as follows, easy to use, survey measurements degree of accuracy is high, measurement range large (position angle 0～360 degree, inclination angle 0～90 degree); Can field fabrication go out the product of different size, for the measurement in different pore size hole.

Parts and numbering in figure:
Protection ring in 1-hole, 2-support, 3-pendulum, 4-surveyors' staff, 5-connecting link, 6-rolling bearing, 7-illuminating lamp, 8-accumulator, 9-rotating shaft.
Embodiment
Below in conjunction with embodiment, the present invention is further described.
Referring to Fig. 1, hole interior positioning-measuring instrument, comprises protection ring 1 in hole; in hole, protection ring 1 top is provided with support 2; the vertical positioner that support 2 center suspensions have pendulum 3 and surveyors' staff 4 to form, the center of circle that is centered close to protection ring 1 in hole of surveyors' staff 4, support 2 is provided with perpendicular connecting link 5.
Vertical positioner is made up of the pendulum 3 of bottom and the surveyors' staff 4 on top; be connected with the central rotation of support 2 by rotating shaft 9; when measurement, protection ring 1 in the hole of instrument is put into and bored the hole of opening; no matter instrument is placed on any position in hole; according to the principle of earth center of gravity power, surveyors' staff 4 is positioned at the central point in hole all the time.
In hole, four of protection ring 1 quadrantal points places are inlaid with rolling bearing 6.In hole, protection ring 1 adopts the weldless steel tube consistent with aperture to process, and wall thickness is 10mm, ensures that measuring instrument is in use indeformable, and around steel pipe, inlays four groups of rolling bearings 6, and instrument can be free to slide in hole, is convenient to be in place.
In hole, protection ring 1 both sides, bottom are provided with illuminating lamp 7, and described support 1 top is provided with the accumulator 8 of powering for illuminating lamp 7.
Illuminating lamp 7 adopts shot-light, and its illumination direction remains on surveyors' staff 4, is convenient to reading, and accumulator can use by recharge.
Connecting link 5 adopts the galvanized iron conduit of D15mm to process, and is divided into two kinds of specifications of 1m length and 2m length, is assembled into the connecting link of different length according to different hole depths, measuring instrument can be sent into assigned address in hole.
In drilling construction, in order to prevent the excessive deflection in position, hole, often creep into 5m and use all-station instrument accurate measurement first power parallactic angle, if angular deviation is excessive, must take suitable corrective action.Measuring instrument physical dimension: length 300mm, outer diameter of steel pipes 300mm, wall thickness 10mm, general assembly (TW) 21kg, can coordinate the measured value of aperture place total powerstation to draw position angle and the inclination angle of boring at different depth.
Specific operation process is as follows:
First total powerstation is set up in the position overlapping with centerline hole in aperture, and near the earth observation station utilizing is determined the longitude and latitude of total powerstation; Then hole interior positioning-measuring instrument is sent into hole depth point to be measured by connecting link 5, utilize total station survey to go out elevation and the position angle of this point; Finally measurement data and design load are compared, calculate inclination angle and azimuthal amount of deflection of measurement point, coordinate the measured value of total powerstation to draw position angle and the inclination angle of boring at different depth.
The present invention succeeds increasing project for the Sudan's sieve Ferenc Seres dam.This project gate pier prestress super-tonnage anchor cable is distributed on 8 concrete buttresses, and anchor cable is compiled Shu Ercheng by the underrelaxation of 55 1860MPa grade high-strengths without bonding steel hinge line, design locking load 10439KN, perpetuity load 9581KN.Only 4m of gate pier width, anchor cable duct is arranged in gate pier inside, and design adopts from downstream drilling on inclined surface.Drilling design aperture is D325mm, and hole depth is respectively 25m and 32m, and hole depth construction error is not more than 0.2m; Bore direction angular displacement requires≤1 degree; Dip angle of hole error is respectively 5.70 ± 0.80 degree, 25.10 ± 0.70 degree; At the bottom of hole, place-centric line and theoretical value deviation are in 0.35m.
