In summary, a plurality of foundation piles 1 are poured by concrete to form foundation pit enclosure, then a clamping seat 31 is placed at the upper end of the foundation pile 1 according to the structure of the foundation pile 1 and the position to be detected, two locking plates 33 are driven to draw close inwards by tightening double-headed screws 34, four clamping jaws 32 are pulled to clamp the foundation pile 1, traction steel ropes 41 between every two are prefastened, a plurality of traction steel ropes are connected in series, the traction steel ropes on reference points on two sides are stretched, the whole traction steel ropes are straightened, measurement errors are avoided by utilizing the straightening, an index table 22 is arranged on a central column 44 after zeroing, the fixing effect of the central column 44 and the index table 22 is ensured, when soil changes occur at the outer side or the inner side of the foundation pit enclosure to enable the foundation pile 1 to deviate, the foundation pile 1 at the main deviation position is deviated, at this time, the traction steel ropes 41 inside the foundation pile 1 at the main offset position start to pull the traction steel ropes 41 at the two sides, the winding drum 42 at the main offset center position and the traction steel ropes 41 on the winding drums 42 at the two sides are pulled out towards the center direction, so that the traction steel ropes 41 at the outer side of the main offset center are filled towards the center, in the pulling process, each winding drum 42 is subjected to corresponding pulling force to rotate, the winding drum 42 transmits the amplified rotation degrees to the center column 44 through the planetary gear set 45, the center column 44 drives the index table 22 to display the amplified degrees on the index table 22, thereby intuitively observing the offset of each foundation pile 1, and because the main offset center position is the main pulling position, the winding drums do not rotate, the traction steel ropes on the winding drums extending towards the outer side at the main offset center position gradually become larger, the main offset center is taken as a symmetry center, the indication numbers on two sides gradually become larger outwards, and the minimum indication number is found according to linear change, so that the main offset center is found;
when the outside traction steel rope 41 fills up towards the center, because the foundation pile 1 is in the complex environment of the construction site, because of wind, sun and the like, the traction steel rope 41 is coated with an anti-rust coating in time, but because soil dust is extremely easy to adhere to the traction steel rope 41 after contacting moisture in the air, meanwhile, because soil forms caking on the surface of the traction steel rope 41 after being subjected to multi-layer wet drying, if the traction steel rope 41 can not timely clean the caking during retraction, the caking can be filled between the traction steel rope 41 and the winding drum 42, the rotation angle of the winding drum 42 is influenced after the traction steel rope 41 is retracted, the whole measurement precision is influenced, so when the traction steel rope 41 is retracted to drive the winding drum 42 to rotate, the winding drum 42 drives the impurity removal power gear 51, the impurity removal power gear 51 utilizes the crank rocker principle through the remote rod 52 and the push rod 53, the lower end scraping plate 54 and the upper end scraping plate 55 are driven by the rotation power of the impurity removal power gear 51 to form telescopic movement, meanwhile, the lower end scraping plate 54 and the upper end scraping plate 55 are installed through the eccentric structure of the traction rod 56, when the upper end scraping plate 55 is driven by the lower end scraping plate 54 to move outwards, the lower end scraping plate 54 is eccentrically pulled by the upper end scraping plate 55 and the traction rod 56, the arc part is better attached to the traction steel rope 41, the arc part of the upper end scraping plate 55 is better attached to the traction steel rope 41, the eccentric blocks 59 of the wave structure are matched with the swinging rods 58, the swinging rods 58 regularly swing at two sides when sliding in the bottom limiting seat 57, and the swinging rods 58 can vibrate through the collision of the eccentric blocks 59, so that the swinging and vibrating of the pushing rods 53 can be transmitted to the lower end scraping plate 54, the lower end scraper blade 54 can swing and vibrate around the traction steel rope 41, and the lower end scraper blade 54 and the upper end scraper blade 55 simultaneously have power of swing, vibration and expansion, so that mud blocks bonded on the traction steel rope 41 are cleaned, the cleaning of the traction steel rope 41 is ensured, the matching effect with the winding drum 42 during tightening is improved, and the detection precision is improved.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
