The purpose of the utility model is to provide geometry that utilization acquires and mathematical knowledge to make one can not only accurately measure the aperture of hole different depth and a degree of depth; And simple in structure, easy operation, usage charges are low, and are suitable for the stake hole depth diameter ordinary surveying device of different aperture stake hole measurements.
For reaching above purpose; The technical scheme that the utility model adopted is: this hole depth diameter ordinary surveying device constitutes central circular on the center fixation of " ten " word carriage by " ten " word carriage and central circular; It is characterized in that in central circular, being provided with rolling disc; On rolling disc, be provided with rectangular through holes, in rectangular through holes, fix crossfoot, fix miter square at the rear side of rolling disc through bearing pin; On miter square, be provided with sliding sleeve, horizontal ruler the left and right side of sliding sleeve is fixing.
The utility model is also implemented through following measure: be provided with telescopic inner sleeve in the lower end tube chamber of described crossfoot, inner sleeve is established 2-4 joint, every joint 2-3m; On the lateral wall of the internal segment bottom of inner sleeve, be provided with the ball cave, in the ball cave, be provided with ball, in inner sleeve, be provided with expansion link; Stretch out from the upper end of crossfoot the upper end of expansion link, and the lengthening insertion through expansion link can make inner sleeve stretch; Thereby scalable fathoms, and the stake aperture, hole of different depth; When turn disc, ball can roll by inwall along the stake hole, through the rotation of rolling disc, observes the data variation of crossfoot upper end on horizontal ruler simultaneously, can measure a smoothness of hole hole wall.
Described horizontal ruler is provided with level meter, and described miter square is provided with weight, measures the levelness of " ten " word carriage through level meter and weight.
Described " ten " word carriage connect to be gone up folding arm through rotation axis, after measuring, can crossfoot be shortened, will fold arm and fold up, so that carry.
Described expansion link is made up of column joint, joint with save between be connected through threaded connector, joint number can add deduct according to the requirement of the lower end collapsing length of crossfoot.
The beneficial effect of the utility model is: this hole depth diameter ordinary surveying device, owing to be the machine applications of the mathematical knowledge acquired of student, so simple in structure, easy to use, cost of manufacture is low, usage charges are low.And structurally owing to collapsible, so be easy to carry, be convenient to install.The aperture of different depth can not only be measured, the smooth degree of hole wall can also be measured.Can be widely used in the quality testing of pile hole of building.
