Abstract
The invention discloses a pipe pile perpendicularity tester. Based on the principle for utilizing a conventional inclinometer to test the perpendicularity of an inclinometer casing, a special wheel frame is installed so that the pipe pile perpendicularity tester can freely slide up and down along the inner wall of a pipe pile, and the attitude of a probe is always kept to be parallel to the pipe pile. The perpendicularity of the inner wall of the pipe pile is tested at intervals of 0.5 m, vectors in the eastern and western directions and vectors in the southern and northern directions are added, and finally the overall inclination conditions of the pipe pile are obtained.
Description
Technical field
Pile tube is as the important vertical load-carrying members of foundation, and when more obviously tilting appears in pile tube, pile tube cannot bear the various loads of designing requirement, so must rectify a deviation to pile tube.Adopt pile tube perpendicularity detecting apparatus can accurately measure pile tube deformation, this method of testing contributes to pile tube to carry out science correction.
Background technology
Pile tube perpendicularity detecting apparatus is to utilize conventional inclinometer that its external smooth guide wheel sliding of pile tube inwall that can be allowed to condition at is converted.Conventional inclinometer test philosophy: instrument changes by the inclination angle [theta] of measuring between clinometer probe and vertical line, can draw as calculated the horizontal offset at different depth position.
Summary of the invention
In order to make conventional inclinometer can measure the distortion of pile tube, must accomplish 2 points: the first, clinometer probe in gaging hole must with gaging hole depth direction keeping parallelism, can not there is the probe and the uneven situation of gaging hole depth direction that because of gravity factor, produce; The second, make clinometer probe in gaging hole constantly in center, can not there is the situations such as any torsion or deflection in the attitude of probe in gaging hole.Conventional inclinometer, in order to meet above two conditions, has been equipped with special-purpose inclinometer pipe.First, pile tube internal diameter (being generally greater than 300mm) is far longer than inclinometer pipe internal diameter (51mm ~ 76mm) but as the pile tube of tested object and common inclinometer pipe, have very large difference,, the guide wheel of inclinometer self configuration cannot be for testing bigbore pile tube; Secondly, pile tube inwall is for the groove of static probe direction, keep clinometer probe parallel more difficult with pile tube depth direction.
Pile tube perpendicularity detecting apparatus has overcome above-mentioned 2 difficulties, and inclinometer wall energy in pile tube is slided smoothly, and can the distortion of Measurement accuracy pile tube.Pile tube gradient tester does not carry out destructiveness repacking to original inclinometer, just in original inclinometer outside, has installed large guide wheel and the external support that is applicable to pile tube inclining test additional.This internal stent has been installed spring, can allow like this guide wheel at support two ends adapt to different pile tube internal diameters, and spring by compression after, thereby the extruding force towards two ends makes guide wheel, the frictional force that pile tube inwall makes guide wheel that slippage occur in horizontal plane that touch tightly increases greatly, guaranteed that guide wheel is after slipping into pile tube, the torsion of instrument in can occurred level face, being so just equivalent to pile tube inwall has a directed groove.At two pairs of guide wheels of direction configuration of needs tests, guarantee that inclinometer enters the direction of popping one's head in after pile tube parallel with the direction of tube wall.Meanwhile, for the skew of vertical checkout direction does not occur clinometer probe in pile tube, at clinometer probe middle part, add the guide wheel of a pair of vertical checkout direction, guarantee that the attitude that probe enters after pile tube keeps placed in the middle.At pile tube mouth, with red paint, mark and draw direction, guarantee the accuracy of instrument test direction, pile tube gradient tester need to carry out the test of forward and reverse direction equally, for eliminating the drift of instrument itself.
Accompanying drawing explanation
The conventional inclinometer of Fig. 1, Fig. 2 pile tube perpendicularity detecting apparatus, Fig. 3 pile tube perpendicularity detecting apparatus test philosophy figure, Fig. 4 pile tube perpendicularity detecting apparatus attitude in pile tube, Fig. 5 pile tube mouth has marked the red paint of direction, the first pair of guide wheel of Fig. 6 installed, and the 3rd pair of guide wheel of Fig. 7 installed, and Fig. 8 tightens screw outside guide wheel, Fig. 9 inclinometer is put into pile tube, Figure 10 inclinometer data wire is aimed at batten centre, Figure 11 test data record, and Figure 12 inclination engineering pile test data is processed outcome table.
The specific embodiment
Before pile tube inclining test, require test pile tube to carry out inner wall washing, the mud skin that pile tube inwall is adhered to cleans up, and ponding is extracted out simultaneously.The pile tube special test guide wheel that tilts is arranged on inclinometer, guide wheel has 3,3 guide wheels are installed along three positions of clinometer probe minute upper, middle and lower, in the time of installation, it should be noted that go up most a guide wheel installation direction will with inclinometer upper block direction strict conformance, a middle guide wheel is vertical with 90 ° of upper block direction maintenances, the most next guide wheel installation direction will with inclinometer lower tumbler direction strict conformance.After guide wheel is in place, screw screw outside guide wheel, guide wheel and inclinometer are connected firmly.The incline direction of pile tube is arbitrarily, so in order to measure the concrete incline direction of pile tube, need to test along thing and north and south both direction pile tube, by vector superposed, calculates the concrete incline direction of pile tube.During test, by guide wheel spring-compressed, make probe slip into pile tube with pile tube inwall keeping parallelism state, when instrument slides to pile tube bottommost, standing 15 minutes, the interior chip temperature of instrument and environment temperature are consistent.At pile tube top, place a batten, make a limit of batten be positioned at pile tube diametrical position as far as possible, make instrument cable aim at batten center, from bottom to top every the 50cm bracing wire reading that makes progress, after a direction has been tested, test again another one direction, in test process, must treat inclinometer plate reading data stabilization and carry out again data stored record.
Claims (2)
1. pile tube perpendicularity detecting apparatus is the principle of utilizing conventional inclinometer test inclinometer pipe verticality, by three groups of special wheel frames are installed, make its verticality that can test pile tube, solved pile tube in existing underground engineering construction process and rectified a deviation and lack the problem of test data after tilting.
2. three groups of wheel frames are installed rear to mutually orthogonal, to play, controlling pops one's head in is parallel to pile tube wall all the time, guide pulley surface is coarse, by the spring in wheel frame, increase guide wheel towards pile tube pressure radially, make the guide wheel pile tube sidewall of effectively fitting, force guide wheel can only occur along pile tube sidewall upwards or downward movement, and do not occur left and right to skew.
