Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation detection, in particular to a pile foundation settlement detection ruler. Background Art

[0002] A deep foundation consisting of a pile and a pile cap connected to the top of the pile, or a single pile foundation connected by a column and a pile foundation, is referred to as a pile foundation. A measuring ruler is a measuring instrument for linear dimensions, plane calibration and slope, especially a multi-purpose engineering detection method used in civil engineering, characterized by a combination of mechanical and electronic technologies.

[0003] The utility model patent application document with publication number "CN209816946U" discloses a pile foundation settlement detection ruler, which is mainly composed of a pile base body, a block, a vertical ruler, a slide plate, a semicircular ruler, a vertical plate and a balance board. This technical solution has blocks fixedly connected to the top of the base layer and on both sides of the pile base body, which greatly improves the detection efficiency, saves time, and facilitates the operation of the staff. A third pointer is fixedly connected to both sides of the bottom of the balance board, and the detection device is fixedly connected to the pile foundation, thereby improving the accuracy and precision of the detection data.

[0004] The pile foundation settlement detection ruler disclosed in the above document has the following defects: when in use, the detection ruler adjusts the position of the movable plate inside the movable groove by cooperating with the fixing bolts and the threaded holes. Since there is a certain distance between the threaded holes, the position of the movable plate in the movable groove can only be roughly adjusted, and the practical effect is poor.

[0005] It can be seen from this that the existing pile foundation settlement detection ruler does not have a good structure for adjusting the position of the clamping component, and it is necessary to improve the existing shortcomings and provide a pile foundation settlement detection ruler.

[0006] The purpose of the utility model is to provide a pile foundation settlement detection ruler to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model is a pile foundation settlement detection ruler, comprising a base, the base is fixed in two and symmetrically arranged, the upper surfaces of the two bases are both installed with vertical rulers, a slide plate is slidably connected between the two vertical rulers, a first pointer is installed on the outer surface of the slide plate, a connecting shaft is installed in the middle of the slide plate, both ends of the connecting shaft are rotatably connected with connecting plates, a semicircular ruler is installed on the upper surface of the slide plate, a second pointer is installed on the outer surface of one of the connecting plates, a balance plate is installed between the two connecting plates, a movable groove is opened on the upper surface of the balance plate, the movable groove is fixed in two and symmetrically arranged, and clamping components are arranged inside the two movable grooves.

[0009] Furthermore, the clamping assembly includes a slider, a connecting rod is installed on the lower surface of the slider, a connecting block is installed on the lower surface of the connecting rod, a clamping plate is installed on the lower surface of the connecting block, and a baffle is provided on the upper surface of the balance plate. The baffles are fixed in two and symmetrically arranged, and a bidirectional screw is rotatably connected between the two baffles. One end of the bidirectional screw passes through one of the baffles and is installed with a rotating handle. The outer surface of the bidirectional screw is slidably connected to the slider, and the connecting rod is slidably connected to the inside of the movable groove.

[0010] Furthermore, the outer surface of the clamping plate is provided with anti-slip stripes.

[0011] Furthermore, a pile foundation body is arranged between the two clamping plates.

[0012] Furthermore, the clamping assembly also includes a hand-tightening nut and a gasket. The outer surface of the connecting rod is sleeved with a gasket, and the outer surface of the connecting rod is provided with an external thread. The connecting rod is equipped with a hand-tightening nut through the external thread. The lower surface of the gasket abuts against the upper surface of the balance plate, and the upper surface of the gasket abuts against the lower surface of the hand-tightening nut. By using the hand-tightening nut and the gasket in coordination, the fastening between the connecting rod and the balance plate can be increased, and the connecting rod can be prevented from moving inside the movable groove during use, thereby achieving a better fixing effect.

[0013] Furthermore, a plurality of reinforcing nails are provided on the lower surface of the base.

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model replaces the fixing bolt and the threaded hole by the cooperation between the bidirectional screw, the rotating handle and the slider, so that the connecting rod can slide smoothly inside the movable groove and the clamping plate can have a good clamping effect, thereby achieving better practicality.

[0016] (2) The utility model can increase the fastening between the connecting rod and the balance plate by using the hand-tightened nut in conjunction with the gasket, thereby preventing the connecting rod from moving inside the movable groove during use, thereby achieving a better fixing effect.

[0028] The outer surface of the clamping plate 1004 is provided with anti-slip stripes.

[0029] A pile foundation body 13 is disposed between the two clamping plates 1004 .

[0030] The clamping assembly 10 also includes a hand-tightening nut 1005 and a gasket 1006. The outer surface of the connecting rod 1002 is sleeved with the gasket 1006. The outer surface of the connecting rod 1002 is provided with an external thread. The connecting rod 1002 is installed with the hand-tightening nut 1005 through the external thread.

After clamping, stop turning the rotating handle 12, and then turn the hand nut 1005 clockwise to make the hand nut 1005 move downward on the external thread and squeeze the gasket 1006, thereby increasing the fastening between the connecting rod 1002 and the balancing plate 9, avoiding The middle connecting rod 1002 moves inside the movable groove 901, and the fixing bolts and threaded holes are replaced by the cooperation between the bidirectional screw 11, the rotating handle 12 and the slider 1001, so that the connecting rod 1002 can slide smoothly inside the movable groove 901 and the clamping plate 1004 can have a good clamping effect. When the pile foundation body 13 moves downward, it will pull the slide plate 3 to move downward on the vertical ruler 2. The horizontal descent distance of the pile foundation body 13 can be measured by the distance moved by the first pointer 4. If the pile foundation body 13 tilts, the balance plate 9 will also tilt. The offset angle of the second pointer 8 is observed, and data can be obtained through the semicircular ruler 7 to determine the offset angle of the pile foundation body 13.
