Description

Technical Field

[0001] The present invention relates to the technical field of CFG pile construction technology, and specifically to a device for controlling the verticality of CFG pile foundations. Background Technique

[0002] The CFG pile construction technology is currently very mature, and the state also has corresponding specifications for this type of composite foundation. The verticality of the pile body is part of the construction quality control. Currently, the verticality of the pile tube is mainly controlled by using a total station or a theodolite for measurement.

[0003] However, construction is a continuous process, and manual observation cannot be carried out in real time. When it is found that the verticality of the pile body deviates and the pipe is pulled out for correction, part of the materials has already been lost. Moreover, during most of the construction process, if the requirements for the verticality of the pile foundation are ignored or not strictly required, it will cause the single-pile bearing capacity of the pile foundation to not be fully exerted or lead to the pile foundation bearing capacity not meeting the requirements. Although the verticality of the CFG pile is only a general item, if the verticality of the pile body cannot meet the design or specification requirements, it will pose a great safety hazard to the building. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-4, the present invention provides a technical solution: a device for controlling the verticality of CFG pile foundations, including a housing 1. A detection mechanism 5 is provided at the top of the housing 1. The detection mechanism 5 includes a first support base 501, which is fixedly connected to the top of the housing 1. The first support base 501 is rotatably connected to a vertical plate 502 through a connecting shaft. A torsion spring 503 is provided on the front end face of the first support base 501. The torsion spring 503 gives a force to make the vertical rod 502 perpendicular to the housing 1. The inner wall of the torsion spring 503 is in clearance fit with the outer wall of the connecting shaft. The two ends of the torsion spring 503 are respectively fixedly connected to the outer walls of the vertical plate 502 and the first support base 501. An angle scale 506 is fixedly connected to the front end face of the vertical plate 502. One end of the first support base 501 is fixedly connected to a pointer 507. The pointer 507 can cooperate with the angle scale 506 to detect the angle of the vertical plate 502. Second support bases 504 and arc-shaped rods 508 are respectively fixedly connected to the two ends of the vertical plate 502. The second support base 504 is rotatably connected to a roller 505 through a connecting shaft. The roller 505 is used to contact the external CFG pile. The outer wall of the arc-shaped rod 508 is in clearance fit with a second through hole 509. The second through hole 509 is machined on the top of the housing 1. A first through hole 2 is fixedly connected to the top of the housing 1. The inner wall of the first through hole 2 is connected to the inner wall of the housing 1. A net plate 4 is fixedly connected to one end of the housing 1. The net plate 4 is used for the alarm sound generated by the alarm 603 to pass through the housing 1. The inner wall of the net plate 4 is connected to the inner wall of the housing 1. A level 3 is fixedly connected to the top of the housing 1. By contacting the external CFG pile through the roller 505, and when the external CFG pile moves downward, due to the inclination of the external CFG pile, the roller 505, the vertical plate 502, the arc-shaped rod 508 and the angle scale 506 can be driven to rotate to the right. When the angle scale 506 rotates, the inclination angle of the external CFG pile can be detected in real time according to the cooperation with the pointer 507 for the verticality detection.

[0019] An alarm mechanism 6 is provided on the inner wall of the housing 1. The alarm mechanism 6 includes a storage battery 601, which is fixedly connected to the top of the inner wall of the housing 1. The storage battery 601 is electrically connected to an infrared switch 602 through a wire. The model of the infrared switch 602 is LE3K100-7M1. The infrared switch 602 is fixedly connected to one end of the storage battery 601. The infrared switch 602 is electrically connected to an alarm 603 through a wire. The model of the alarm 603 is FKLB. The alarm 603 is fixedly connected to the bottom of the inner wall of the housing 1. When the infrared switch 602 corresponds to the arc-shaped rod 508 that rotates downward with the vertical plate 502, the infrared switch 602 can start the alarm 603 through the storage battery 601, and then give an alarm through the alarm 603 to remind the staff that the external CFG pile is inclined, and conduct real-time monitoring of the verticality of the pile foundation during operation. When it exceeds the design or specification value, it will directly alarm to prompt the relevant construction personnel to adjust the verticality, reduce the quality accidents caused by human reasons, and ensure the construction quality.

[0020] The bottom of the housing 1 is provided with an adjusting mechanism 7. The adjusting mechanism 7 includes a vertical rod 701. The vertical rod 701 is fixedly connected to the bottom of the housing 1. The vertical rod 701 is rotatably connected to a horizontal plate 702 through a connecting shaft. The vertical rod 701 can drive the housing 1 to rotate at the horizontal plate 702, and then cooperate with the level 3 to horizontally place the housing 1. A sliding groove rod 703 is fixedly connected to the top of the horizontal plate 702. A bolt 704 is in clearance fit with the inner wall of the sliding groove rod 703. The outer wall of the bolt 704 is threadedly connected to the inner wall of the vertical rod 701. The bolt 703 is used to limit the rotation of the vertical rod 701 and the housing 1. By rotating the bolt 704 and canceling the fit with the sliding groove rod 703, the vertical rod 701 and the housing 1 can be driven to adjust the angle, and cooperate with the level 3 to horizontally adjust the housing 1 placed on the external ground, which can improve the perpendicularity detection of the external CFG pile by the detection mechanism 5.

[0021] When using the device for controlling the perpendicularity of the CFG pile foundation, the roller 505 contacts the external CFG pile. When the external CFG pile moves downward, the inclination of the external CFG pile can drive the roller 505, the vertical plate 502, the arc-shaped rod 508 and the angle scale 506 to rotate to the right. When the angle scale 506 rotates, the inclination angle of the external CFG pile can be detected in real time according to the cooperation with the pointer 507. When the infrared switch 602 corresponds to the arc-shaped rod 508 that rotates downward with the vertical plate 502, the infrared switch 602 can start the alarm 603 through the storage battery 601, and then the alarm 603 gives an alarm to remind the staff that the external CFG pile is inclined, and the perpendicularity of the pile foundation during operation is monitored in real time. When it exceeds the design or specification value, an alarm is directly given to prompt the relevant construction personnel to adjust the perpendicularity, reduce the quality accidents caused by human reasons, ensure the construction quality, and the vertical rod 701 and the housing 1 can be driven to adjust the angle by rotating the bolt 704 and canceling the fit with the sliding groove rod 703, and cooperate with the level 3 to horizontally adjust the housing 1 placed on the external ground, which can improve the perpendicularity detection of the external CFG pile by the detection mechanism 5.
