Embodiment 1

[0030] like figure 1 , figure 2 The illustrated embodiment is a pile settlement measurement device used in building rectification process, including 13 piles 1 arranged at the bottom of the building, and a first scale 11 arranged on each pile , 13 flat plates 2 on the ground; an opening 3 corresponding to the pile is provided in the middle of the plate, and a vertical plate 4 is provided on the edge of the opening. The cross section of the vertical plate is U-shaped, and the vertical plate is provided with a movable The pointing rod 41 is provided with three uprights 22 on the flat plate, and the upper end of each upright is provided with a laser emitter 23, and each laser emitter is electrically connected with the controller. A circular ring 5 is arranged on the flat plate, and the lower end of each column is slidably connected with the circular ring.

Embodiment 2

[0038] Embodiment 2 includes all structure and method parts of embodiment 1, such as figure 1 As shown, each pile top of embodiment 2 is provided with annulus 12 and pallet 13, is provided with annular cavity in annulus, is filled with 1000 balls in annular cavity, is provided with 15 on the outer wall of annulus. a through hole 14;

[0039] like image 3 As shown, the tray is located below the ring, and the tray is provided with 16 partitions 15 distributed along the circumference, each partition divides the tray into 17 independent spaces 16, and the outer edge of the tray is located outside the outer edge of the ring.

[0040] When the pile tilts and settles, the balls flow out from each through hole on one side of the ring and enter the corresponding independent space in the tray; the staff checks the number of balls in each independent space in the tray of each pile, Through multiple tests, obtain the correspondence table between the number of balls and the inclination ...

Abstract

The invention discloses a pile settlement amount measuring device and method used in the building rectification process. The pile settlement amount measuring device comprises M pile columns arranged at the bottom of a building, first calibrated scales arranged on all the pile columns, and M flat plates arranged on the ground; openings corresponding to the pile columns are formed in the middles ofthe flat plates, and vertical plates are arranged at the edges of the openings; the cross section of each vertical plate is in a U shape, and pointing rods capable of vertically moving are arranged onthe vertical plates; three vertical columns are arranged on each flat plate, and laser transmitters are arranged at the upper ends of all the vertical columns correspondingly; and all the laser transmitters are electrically connected with a controller. The pile settlement amount measuring device and method have the characteristics that the settlement amount and inclination angles of all the pilecolumns can be obtained, and the reliable basis is provided for accurate rectification of the building.

Description

technical field [0001] The invention relates to the technical field of building tilt correction, in particular to a pile settlement measurement device and method used in the process of building tilt correction. Background technique [0002] The site in the soft soil area is complex. Due to the uneven distribution of the soil layer, the depth of the soft soil layer or the design, construction and other factors, the bearing capacity of the engineering piles is insufficient and the distribution of the bearing capacity of the engineering piles is different. It is easy to cause uneven settlement and cause the superstructure to tilt. . Especially in the quasi-limit state of friction piles and end-bearing friction pile foundations, the settlement difference caused by insufficient vertical bearing capacity is difficult to control, which will seriously affect the safe and normal use of buildings. In order to restore the use function of the building, measures such as pile cutting and...
