After pouring, check whether there are any foreign objects or rust layers inside the steel bar connecting sleeve. S2. The cylindrical pier is transported to the construction site. The crane suspends the cylindrical pier. Before hoisting, ensure that the connection between the crane cable and the cylindrical pier is reliable. After hoisting, the verticality of the cylindrical pier is monitored and checked by a total station. S3.

The computer analyzes the data to determine the lateral tilt of the cylindrical pier. The push plate presses against the surface of the cylindrical pier, and the longitudinal tilt is detected by the tilt sensor to determine the overall hanging posture of the cylindrical pier. According to the installation requirements, a second set of upward-viewing visual sensors is set near the pier to detect whether the lower end steel bar connecting sleeve of the cylindrical pier corresponds one-to-one with the upper steel bar of the pier. S7. Based on the above test data, control the movement or extension of the telescopic clamping arm to guide the cylindrical pier column for fine adjustment. If it is necessary to rotate the cylindrical pier column, the telescopic clamping arms on both sides can be controlled. One telescopic clamping arm extends and the other telescopic clamping arm shortens. Apply circumferential force to rotate the cylindrical pier column and ensure that the sleeve and the reinforcing bar are aligned. S8. The crane slowly lowers the cylindrical pier to complete the docking and assembly. Then, using tools such as a total station and laser plumb line, the verticality deviation of the assembled cylindrical pier is checked to see if it meets the design requirements. After the inspection is qualified, the joint is coated with grout and high-strength non-shrink cement is poured into the steel bar connecting sleeve.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0016] Reference Figure 1-8 A device for controlling the installation accuracy of precast pier components includes a crane 1 and an installation forklift 3. The crane 1 is connected to the top of the precast pier component by a steel cable, which lifts and suspends the precast pier component for transport. An installation control device 4 is provided on one side of the installation forklift 3. The installation control device 4 is used to detect and guide the adjustment of the lower end position and overall posture of the precast pier component to ensure that the lower end steel bar connecting sleeve of the precast pier component corresponds one-to-one with the foundation steel bar. The installation control device 4 includes a lifting seat 41, a telescopic clamping arm 43 and a push plate 46. A vertical slide 32 is provided on one side of the forklift 3. The lifting seat 41 is slidably connected to the vertical slide 32 to facilitate the adjustment of the height of the installation control device 4. A drive device corresponding to the lifting seat 41 is provided on the vertical slide 32. The drive device includes a chain, a sprocket and a drive motor. The telescopic clamping arms 43 are slidably arranged in pairs on one side of the lifting seat 41 to facilitate abutting the precast pier column components from both sides. One end of the telescopic clamping arm 43 is provided with a slider 42. The lifting seat 41 is provided with a slide groove corresponding to the slider 42. A hydraulic telescopic rod 421 is provided in the slide groove. One end of the hydraulic telescopic rod 421 is connected to the slider 42, and the other end of the hydraulic telescopic rod 421 is fixedly connected to the lifting seat 41. The slider 42 is driven to slide horizontally in the slide groove by the hydraulic telescopic rod 421 to adjust the position of the telescopic clamping arm 43. The telescopic clamping arm 43 includes a telescopic drive rod, an outer shell and an inner shell. The outer shell is fitted onto the inner shell and is slidably connected to it. The telescopic drive rod is located inside the outer shell and the inner shell. The outer shell and the inner shell provide dust protection and anti-collision, while improving the telescopic stability of the telescopic clamping arm 43. The outer shell is fixedly connected to the slider 42, and a reinforcing rib is provided between the outer shell and the slider 42. The telescopic clamping arm 43 is equipped with a vision sensor 44, which is a top-down view. Multiple vision sensors 44 can be configured according to the installation and construction needs of the precast pier components. The telescopic clamping arms 43 are equipped with contact plates 45 on their adjacent sides. The contact plates 45 include rubber contact blocks 451 and clamping plates 453. One end of the clamping plate 453 is fixedly connected to the end of the inner shell, and the other end of the clamping plate 453 is in sliding contact with the outer shell. The clamping plate 453 can be slightly elastically deformed. The rubber contact blocks 451 are detachably mounted on the clamping plates 453. After wear, deformation or loss of elasticity, new rubber contact blocks 451 can be quickly replaced.
[0017] Strain gauges 452 are provided on the upper and lower sides of the rubber contact block 451. The telescopic clamping arm 43 abuts against the precast pier component. The rubber contact block 451 deforms under force, and the resistance of the upper and lower strain gauges 452 changes. The degree of lateral tilt of the cylindrical pier 2 is determined by the resistance data of the upper and lower strain gauges 452. A push rod 47 is provided on the upper middle part of the lifting seat 41. The push rod 47 is a hydraulic cylinder. One end of the output shaft of the push rod 47 is hinged to the upper middle part of the push plate 46. When the push plate 46 abuts against the surface of the precast pier component, it will deflect. The push plate 46 is equipped with an inclination sensor to detect the longitudinal inclination of the precast pier component. The surface of the push plate 46 is detachably equipped with a wear-resistant strip 461. If the precast pier component has a slope, it can be compensated by replacing the wear-resistant strip 461 with one of different thicknesses to ensure the reliability of the detection. The wear-resistant strip 461 should be replaced in time after wear to avoid affecting the accuracy and reliability of the detection.
