Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
The present invention is in order to solve the deviation survey equipment of prior art or tilt measurement and need to learn in advance shaft or bore its of core hole 11In one whether vertical, could bore again the gradient measurement of core hole 11 or shaft, cause production efficiency low, cannot reclaim etc.Deficiency, provides a kind of cast-in-place concrete pile pile body 10, bores the on-site measurement method of the perpendicularity in core hole 11, as shown in Figure 1,Inclinometer pipe 12 is located at and is bored in core hole 11, is injected with measurement liquid in inclinometer pipe 12, and vertical inclinometer 13 is measured inclinometer pipe 12 differencesCore, with respect to deviant and the perpendicularity in the aperture 111 in brill core hole 11, is bored by deviant and perpendicularity judgement in the measurement position of the degree of depthHole 11 tilts or shaft tilts. In the present embodiment, measurement liquid is clear water, adds measurement liquid in inclinometer pipe 12, as verticallyThe auxiliary material of inclinometer 13, carry out the measurement of deviant for additional vertical inclinometer 13.
Vertical inclinometer 13 is for measuring the skew of the measurement position of inclinometer pipe 12 different depths with respect to the aperture 111 in brill core hole 11Value and perpendicularity, be specially: according to the length of boring the inclinometer pipe 12 in core hole 11, vertical inclinometer 13 main frames 132 are joinedNumber is set, and bores the aperture 111 in core hole 11 for starting at position, measures inclined to one side at two orthogonal directions of inclinometer pipe 12 measuring on positionThe amount of moving, calculates respectively the vector of the side-play amount of the both direction of each depth location, and vector is deviant. Perpendicularity is inclined to one sideThe value of moving and the ratio of measuring bit depth.
The top of inclinometer pipe 12 is higher than the aperture 111 of boring core hole 11, and the top of inclinometer pipe 12 should be controlled higher than the length in aperture 111Between 45cm～55cm.
As shown in Figure 2 and Figure 3, inclinometer pipe 12 comprises some son pipes 121, and 121 of son pipes connect by sleeve 122,The end sealing of the sub-pipe 121 of lowermost end.
The installation process of inclinometer pipe 12 is:
For the end of the sub-pipe 121 of lowermost end, bottom 124 is installed and is sealed, each knot pipe 121 is used to sleeve 122 successivelyAfter connecting, injection is bored in core hole 11, in penetration process simultaneously to the interior injection clear water of inclinometer pipe 12, when the sub-pipe 121 of lowermost endEnd arrives to bore behind 11 bottoms, core hole and stops injection, and the sub-pipe 121 of top exposes aperture 111 length of boring core hole 11 should be controlledBetween 45cm～55cm.
Sleeve 122 surroundings are fixed with soft backing plate 123, and the thickness of soft backing plate 123 is enough resisted against the inwall that bores core hole 11,Ensure that inclinometer pipe 12 does not rock or position skew in brill core hole 11. In order to facilitate the dismounting of inclinometer pipe 12, soft backing plate123 outside is lubricated processing, makes the dismounting of inclinometer pipe 12 in brill core hole 11 more smooth and easy.
The manufacturing process of soft backing plate 123 is:
(1) measurement of brill core hole 11 diameters and inclinometer pipe 12 sleeve 122 external diameters: adopt with slide measure and measure successively and bore core hole11 average diameter D1 and sleeve 122 mean outside diameter D2, should be not less than ± 1mm of accuracy in measurement;
(2) processing of soft backing plate 123: at the fixing soft backing plate 123 of inclinometer pipe 12 sleeve 122 surroundings, as flexible foamBacking plate 123, soft backing plate 123 thickness d=(D1-D2)/2, and lubricated is done in the outside of soft backing plate 123;
Vertical inclinometer 13 comprises probe 131, main frame 132, and probe 131 enters inclinometer pipe 12 with the step pitch of fixing. Inclinometer pipe12 inwall is provided with guide rail 125 along its length, and probe 131 enters inclinometer pipe 12 along guide rail 125. In the present embodiment, fourGuide rail 125 extends projection by the inwall of inclinometer pipe 12 towards center, the end of probe 131 is the guide wheel mating with guide rail 125,Guide wheel and guide rail 125 are realized and being slidably connected.
Squareness measurement is specially: by the probe of vertical inclinometer 13 131 be connected with main frame 132, energising, preheating, along deviational surveyThe guide rail 125 of pipe 12 is put into probe 131, and the parameter measurement inclinometer pipe 12 of setting according to vertical inclinometer 13 is two orthogonal sidesTo side-play amount, calculate respectively the vector of the side-play amount of the both direction of each depth location, be and bore core hole 11 in depth HPlace is with respect to the side-play amount A in aperture 111H, bore 11Cong aperture, the core hole 111 perpendicularity I to depth H placeH＝AH/H。
After measurement completes, need to reclaim inclinometer pipe 12 time, extract the measurement liquid in inclinometer pipe 12 out, by inclinometer pipe 12 from boring coreIn hole 11, take out, and remove successively the connection of 121 of each knot pipes, complete the recovery of inclinometer pipe 12.
Above-described embodiment is only for the present invention is described, and not as limitation of the invention. As long as foundation skill of the present inventionArt essence, to above-described embodiment change, modification etc. all will drop in the scope of claim of the present invention.
