Abstract
The invention discloses an in-hole positioning measuring instrument, and belongs to the technical field of engineering measurement. 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, especially the measurement mechanism that uses in the boring belongs to the engineering measuring technology field.
Background technology
At present, the dam in the hydraulic engineering is increased in the construction, needs to hole on gate pier, arrange anchor cable therein, azimuth deviation during boring and error of tilt accuracy requirement are higher, need during boring it is carried out synchro measure, and electromagnetic teleclinometer commonly used can't use owing to be subjected to the influence of reinforcing bar in the concrete.
Summary of the invention
At the problems referred to above, the invention provides position measuring instrument in a kind of hole.
The technical solution adopted for the present invention to solve the technical problems is: position measuring instrument in the hole; comprise protection ring in the hole; protection ring top is provided with support in the hole; 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 the 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 height, measurement range big (position angle 0～360 degree, inclination angle 0～90 degree); But field fabrication goes out the product of different size, is used for the measurement in hole, different aperture.
Description of drawings
Fig. 1 is a general structure synoptic diagram of the present invention;
Fig. 2 is the A-A cut-open view of Fig. 1.
Parts and numbering among the figure:
Protection ring in the 1-hole, 2-support, 3-pendulum, 4-surveyors' staff, 5-connecting link, 6-rolling bearing, 7-illuminating lamp, 8-accumulator, 9-rotating shaft.
Embodiment
The present invention is further described below in conjunction with embodiment.
Referring to Fig. 1, position measuring instrument in the hole comprises protection ring 1 in the hole; protection ring 1 top is provided with support 2 in the hole; the vertical positioner that support 2 center suspensions have pendulum 3 and surveyors' staff 4 to constitute, the center of circle that is centered close to protection ring 1 in the 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 rotatably connected by the center of rotating shaft 9 with support 2; during measurement protection ring 1 in the hole of instrument put into and bore the hole of opening; no matter instrument is placed on any position in the 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.
Four of protection ring 1 quadrantal points places are inlaid with rolling bearing 6 in the hole.Protection ring 1 adopts the weldless steel tube consistent with the aperture to process in the hole, and wall thickness is 10mm, guarantees that measuring instrument is in use indeformable, and inlay four groups of rolling bearings 6 around steel pipe, and instrument can be free to slide in the hole, is convenient to be in place.
Both sides, protection ring 1 bottom are provided with illuminating lamp 7 in the hole, and described support 1 top is provided with the accumulator 8 into illuminating lamp 7 power supplies.
Illuminating lamp 7 adopts shot-light, and its illumination direction remains on the surveyors' staff 4, is convenient to reading, but the accumulator recharge uses.
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 the hole.
In drilling construction, in order to prevent the excessive deflection in position, hole, whenever 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 cooperate the measured value of place, aperture total powerstation to draw position angle and the inclination angle of boring at different depth.
Specific operation process is as follows:
At first total powerstation is set up in the position that overlaps with centerline hole in the aperture, and near the earth observation station utilizing is determined the longitude and latitude of total powerstation; Then position measuring instrument in the hole is sent into hole depth point to be measured by connecting link 5, utilize total station survey to go out the elevation and the position angle of this point; At last measurement data and design load are compared, calculate inclination angle and azimuthal amount of deflection of measurement point, cooperate the measured value of total powerstation to draw position angle and the inclination angle of boring at different depth.
The present invention increases project and succeeds being used 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 does not have the bonding steel hinge line by the underrelaxation of 55 1860MPa grade high-strengths and compiles Shu Ercheng, design locking load 10439KN, perpetuity load 9581KN.The gate pier width is 4m only, and the anchor cable duct is arranged in gate pier inside, and design is adopted and holed from the inclined-plane, downstream.Boring design aperture is D325mm, and hole depth is respectively 25m and 32m, and the hole depth construction error is not more than 0.2m; Bore direction angular displacement requires≤1 degree; The dip angle of hole error is respectively 5.70 ± 0.80 degree, 25.10 ± 0.70 degree; Place-centric line and theoretical value deviation are in 0.35m at the bottom of the hole.
