[0002] There are many types of pile foundations for construction projects, but concrete bored piles are usually used. Pile foundations have the characteristics of high bearing capacity, small and relatively uniform settlement, and can be applied to almost all engineering geological conditions and various types of projects. They are especially suitable for heavy buildings built on soft foundations. Therefore, pile foundations are widely used in coastal and soft soil areas. In coastal areas, along rivers and lakes, due to the special geographical location, a large number of buildings are located in silt or silty soil areas. Due to the relatively soft geology, displacement often occurs when pre-buried pile foundations.

[0003] Although the pile foundation positioning device of the prior art can have a certain control effect on the deviation of the pile foundation, the pile foundation positioning device of the prior art still has the following disadvantages:

[0004] 1. When driving the pile foundation, the positioning device of the prior art is complicated to operate, and multiple positioning and calibration are required to clamp and fix the pile foundation, resulting in low construction efficiency. In addition, it is difficult to judge the verticality of the pile foundation by naked eyes, which may still cause deviation when the pile foundation is nailed in later, affecting the stability of the building in the later stage and increasing the risk of residents after moving in.

[0005] 2. After the pile foundation is installed, the installation and positioning method of the prior art is relatively complicated, and it is inconvenient to adjust the angle of the pile foundation, which makes it difficult for the pile foundation to meet the standards on the engineering drawings. There is a certain error, causing the pile foundation to tilt at a certain angle, threatening the safety of the superstructure.

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Please see attached Figure 1 and attached Figure 2 A pile foundation positioning and anti-deviation device for pile foundation engineering comprises a base plate 1, a positioning and adjusting component, a sliding clamping component and an anti-sliding block 24; a mounting hole 26 is formed in the middle of the base plate 1, and the diameter of the mounting hole 26 is larger than the diameter of the pile foundation 25. The sliding clamping component is movably arranged on the base plate 1 and is located beside the mounting hole 26, so that the sliding clamping component can be clamped on the pile foundation 25, and the pile foundation 25 vertically passes through the base plate 1 through the mounting hole 26; a plurality of groups of positioning and adjusting components are respectively arranged at the edge of the base plate 1, and the top surfaces of a plurality of anti-sliding blocks 24 are respectively connected to the bottoms of a plurality of groups of positioning and adjusting components, so that the plurality of anti-sliding blocks 24 can be lifted and lowered below the base plate 1; anti-slip teeth 19 are evenly distributed on the bottom surfaces of the plurality of anti-sliding blocks 24, so that the plurality of anti-sliding blocks 24 are fixed to the ground around the pile foundation 25 through the anti-slip teeth 19.

[0028] When the base plate 1 is sleeved on the pile foundation 25 through the mounting hole 26, the pile foundation 25 can be clamped by the sliding clamping assembly. Preferably, the diameter of the mounting hole 26 can be slightly larger than the diameter of the pile foundation 25, so as to ensure that the pile foundation 25 passes through the base plate 1, and the pile foundation 25 can play a certain guiding and positioning role during construction. Preferably, the base plate 1 is a square thick plate, and four sets of positioning and adjustment assemblies are symmetrically arranged at the four corners of the square thick plate. The center of the mounting hole 26 coincides with the center of the base plate 1, so as to ensure uniform force during use.

[0029] The anti-slip block 24 is used to be fixed on the ground around the pile foundation 25, and can be stably inserted into different soil bodies through the anti-slip teeth 19, ensuring the stability of the installation of the base plate 1 on the ground and good adaptability. The anti-slip block 24 can adjust the height through four sets of positioning adjustment components, thereby adjusting the horizontality of the base plate 1, that is, the angle of the base plate 1 relative to the ground.

[0030] If the pile foundation 25 tilts during the striking construction, after the pile foundation 25 and the base plate 1 are clamped and fixed relative to each other by a sliding clamping assembly, the horizontality of the base plate 1 can be adjusted to provide a pulling force to the pile foundation 25, and the verticality of the pile foundation 25 can be adjusted simultaneously to ensure that the construction of the pile foundation 25 meets the design requirements.

[0031] Please see attached Figure 1 and attached Figure 2 Each group of the positioning and adjustment components includes a threaded rod 18, a movable bracket and a first manual rotation mechanism; a threaded hole is formed on the base plate 1, and the threaded rod 18 is matched with the base plate 1 through the threaded hole and screwed and vertically penetrates the base plate 1; a sliding groove 16 is formed on the base plate 1 next to the threaded hole, and the movable bracket can vertically slide through the base plate 1 through the sliding groove 16; the upper end of the threaded rod 18 can rotatably penetrate the top of the movable bracket and is fixedly connected to the first manual rotation mechanism, and the lower end of the threaded rod 18 can be rotatably connected to the middle of the top surface of the anti-sliding block 24 through a rotating bearing, and the lower end of the movable bracket is fixedly connected to the side of the top surface of the anti-sliding block 24.

[0032] The threaded rod 18 is installed on the base plate 1 through a movable bracket, and the threaded transmission between the threaded rod 18 and the threaded hole is utilized. Since the movable bracket slides up and down relative to the base plate 1 through the sliding groove 16, the rotation of the movable bracket is restricted, and the rotation of the threaded rod 18 is converted into a linear lifting motion of the threaded rod 18 and the movable bracket, thereby realizing the lifting and lowering adjustment of the anti-sliding block 24 relative to the base plate 1.

[0033] The first manual rotation mechanism is used to manually provide a driving force for the threaded rod 18 to rotate, which is easy to operate and labor-saving.

[0034] Please see attached Figure 1 and attached Figure 2The movable bracket includes a connecting plate 20 and a sliding rod 17; the sliding rod 17 can slide through the sliding groove 16, the upper end of the sliding rod 17 is located above the bottom plate 1 and fixedly connected to the connecting plate 20, and the lower end of the sliding rod 17 is located below the bottom plate 1 and fixedly connected to the anti-sliding block 24; the upper end of the threaded rod 18 upwardly penetrates the middle part of the connecting plate 20 and is fixedly connected to the first manual rotation mechanism.

[0035] Preferably, two sliding rods 17 can be provided and arranged symmetrically about the second threaded rod 18, and two sliding grooves 16 are also provided accordingly. The sliding rod 17 slides and rises and falls along the sliding groove 16 relative to the base plate 1, which can make the linear lifting and lowering movement process of the second threaded rod 18 and the movable bracket more stable.

[0036] Please see attached Figure 1 and attached Figure 2 The first manual rotating mechanism includes a rotating wheel 22 and a turning handle 23; the rotating wheel 22 is coaxially fixed to the upper end of the threaded rod 18, and the turning handle 23 is vertically installed at the side edge of the rotating wheel 22 away from the threaded rod 18.

[0037] Through the eccentric setting of the turning handle 23, the rotating wheel 1 22 can be easily and labor-savingly driven to rotate under manual operation, thereby controlling the rotation of the threaded rod 2 18, and the manual operation is simple and labor-saving.

[0038] Please see attached Figure 1 and attached Figure 2 The sliding clamping assembly includes a clamping block 12, a clamping mechanism and a sliding mechanism; the sliding mechanism is arranged on the base plate 1 and is located beside the mounting hole 26, one end of a pair of clamping mechanisms is movably connected to the sliding mechanism, and the other ends of a pair of clamping mechanisms are respectively connected to the outer walls of a pair of clamping blocks 12; a pair of clamping blocks 12 and a pair of clamping mechanisms are symmetrically arranged on both sides of the mounting hole 26, so that a pair of arc-shaped plate-shaped clamping blocks 12 can be movably clamped on the pile foundation 25.

[0039] The size of the clamping block 12 can be selected according to the size adaptability of the pile foundation 25 , so that the pile foundation 25 can be stably and reliably clamped by a pair of arc-shaped plate-shaped clamping blocks 12 , making it easy to adjust the verticality of the pile foundation 25 .

[0040] The sliding mechanism is used to provide a synchronous driving force for the pair of clamping mechanisms, so that the pair of clamping mechanisms synchronously push the pair of clamping blocks 12 close to the pile foundation 25, thereby realizing the clamping operation of the pair of clamping blocks 12 on the pile foundation 25. Similarly, the sliding mechanism can also be used to provide a synchronous pulling force for the pair of clamping mechanisms, so that the pair of clamping mechanisms synchronously move the pair of clamping blocks 12 away from the pile foundation 25, thereby realizing the release operation of the pair of clamping blocks 12 on the pile foundation 25.

[0041] Please see attached Figure 3The two ends of the pair of clamping blocks 12 are respectively formed with fixing plates 29, and positioning holes 13 are formed on the fixing plates 29. The two ends of the bolt 14 are respectively inserted into the positioning holes 13 of the two fixing plates 29 on the same side of the pair of clamping blocks 12, and are locked and fixed by nuts 15, so that the pair of clamping blocks 12 are clamped on the pile foundation 25.

[0042] The two fixing plates 29 at the same side ends of a pair of clamping blocks 12 can fit together or be arranged parallel to each other, so that the two ends of the bolt 14 can vertically pass through the two fixing plates 29 through the positioning holes 13, and the two ends of the bolt 14 are abutted against the two fixing plates 29 by tightening the nuts 15. The four fixing plates 29 at both ends of the pair of clamping blocks 12 are locked synchronously, thereby realizing reliable clamping of the pile foundation 25 by the pair of clamping blocks 12, and its principle is similar to that of a clamp.

[0043] Please see attached Figure 1 and attached Figure 2 Each group of the clamping mechanisms includes a connecting rod 1 7, a connecting rod 2 9, a connecting block 10 and a fixed column 11; one end of the connecting rod 1 7 is slidably connected to the sliding mechanism, the other end of the connecting rod 1 7 is rotatably connected to one end of the connecting rod 2 9 through a rotating shaft, and the other end of the connecting rod 2 9 is fixedly connected to the middle of the outer wall (the side away from the pile foundation 25) of the clamping block 12 through the connecting block 10; the fixed column 11 is fixedly set on the base plate 1, and a rotating hole is formed in the middle of the connecting rod 1 7, and the fixed column 11 passes through the rotating hole, so that the connecting rod 1 7 can be rotatably set on the base plate 1.

[0044] The sliding mechanism is used to provide power to one end of the connecting rod 7, so that the connecting rod 7 rotates around the fixed column 11, thereby rotating the other end of the connecting rod 7. When the other end of the connecting rod 7 rotates close to the pile foundation 25, the clamping block 12 is pushed close to the pile foundation 25 through the connecting rod 29 and the connecting block 10 to achieve the clamping action.

[0045] The connecting rod 2 9 and the connecting rod 1 7, as well as the connecting rod 1 7 and the sliding mechanism are all connected by a rotating shaft, so as to adapt to the angle changes of the connecting rod 2 9 and the connecting rod 1 7, ensuring that the clamping block 12 can perfectly fit on the surface of the pile foundation 25, thereby ensuring the reliability of clamping the pile foundation 25.

[0046] Please see attached Figure 1 and attached Figure 2The sliding mechanism includes a fixed block 2, a threaded rod 3, a sliding block 4, a guide rail 5, a sliding column 8 and a second manual rotation mechanism; the fixed block 2 with a threaded hole in the middle is fixedly set on the base plate 1, the threaded rod 3 is screwed through the fixed block 2 by thread matching, and one end of the threaded rod 3 is rotatably connected to the sliding block 4 through a rotating bearing and the middle of the sliding block 4; a pair of guide rails 5 are respectively arranged on the base plate 1 and are parallel to both sides of the threaded rod 3, and the two ends of the sliding block 4 are respectively slidably connected to the pair of guide rails 5; a pair of symmetrically arranged inclined slide grooves 6 are formed on the sliding block 4, the sliding column 8 is slidably embedded in the inclined slide groove 6, and one end of the connecting rod 7 is rotatably connected to the sliding column 8 through a rotating shaft; the other end of the threaded rod 3 is fixedly connected to the second manual rotation mechanism.

[0047] Preferably, the sliding block 4 can be slidably connected with the T-shaped guide rail 5 by using a T-shaped slider, and is not easy to derail. Under the restriction of the pair of guide rails 5, the sliding block 4 will not rotate with the threaded rod 3, and the threaded rod 3 rotates relative to the sliding block 4 through the rotating bearing, ensuring that the sliding block 4 only moves linearly along the pair of guide rails 5, and the movements of the two do not interfere with each other.

[0048] The threaded rod 3 and the fixed block 2 are connected by a threaded transmission, and the rotation of the threaded rod 3 is converted into the axial linear motion of the threaded rod 3. When the threaded rod 3 makes the axial linear motion, it drives the sliding block 4 to move synchronously along a pair of guide rails 5, thereby using the inclined slide groove 6 to drive one end of the connecting rod 7 to move synchronously.

[0049] Due to the oblique setting of the inclined slot 6, when the sliding block 4 slides linearly, the sliding column 8 can generate axial and radial movement along the inclined slot 6 along the threaded rod 3, and act on one end of the connecting rod 7, so that the connecting rod 7 can rotate around the fixed column 11.

[0050] Please see attached Figure 1 and attached Figure 2 The second manual rotating mechanism includes a rotating wheel 27, a gripping portion 28 and an eccentric column 30; the other end of the threaded rod 3 is coaxially fixedly connected to the rotating wheel 27, the eccentric column 30 is vertically connected to the edge of the rotating wheel 27 away from the threaded rod 3, and the gripping portion 28 is sleeved on the eccentric column 30.

[0051] Preferably, the gripping portion 28 may be a rubber anti-slip sleeve to facilitate the gripping and manual rotation of the eccentric column 30. The eccentric column 30 may be manually rotated and drive the rotating wheel 27 to rotate synchronously, and drive the threaded rod 1 3 to realize forward or reverse rotation.

[0052] Please see attached Figure 1 To Attachment Figure 3 , the use method and working principle of the present invention are:

[0053] After the pile foundation 25 is hoisted in place, the bottom plate 1 is mounted on the pile foundation 25 through the mounting hole 26, so that the pair of clamping blocks 12 are sleeved on the outside of the pile foundation 25, and the nuts 15 are not locked at this time. The bottom surfaces of the four anti-slip blocks 24 are fixedly inserted into the ground around the pile foundation 25 through the anti-slip teeth 19, so that the bottom plate 1 is in a horizontal state.

[0054] The pile foundation 25 can be struck to sink into the pile hole. If the pile foundation 25 tilts, the eccentric column 30 drives the rotating wheel 27 to rotate, and the rotating wheel 27 drives the threaded rod 1 3 to rotate. Under the transmission of the thread, the threaded rod 1 3 makes a horizontal linear motion relative to the fixed block 2 and pushes the sliding block 4 to move synchronously along the pair of guide rails 5. Under the guidance of the pair of inclined slide grooves 6, the sliding column 8 drives one end of the connecting rod 1 7 to slide synchronously along the inclined slide groove 6, so that the connecting rod 1 7 rotates around the fixed column 11, so that the other end of the connecting rod 1 7 rotates to the side close to the pile foundation 25, and the clamping block 12 is pushed close to the pile foundation 25 through the connecting rod 2 9 and the connecting block 10, and the locking nut 15 is tightened to clamp the pair of clamping blocks 12 on the pile foundation 25.

[0055] The handle 23 is turned to drive the rotating wheel 1 22, the rotating rod 21 and the threaded rod 2 18 to rotate synchronously. The threaded rod 2 18 rotates relative to the bottom plate 1 through thread transmission. Under the guidance of a pair of sliding rods 17, the threaded rod 2 18 is lifted and lowered relative to the bottom plate 1, thereby adjusting the height of the anti-sliding block 24. The height adjustment of the four anti-sliding blocks 24 can form a traction on the pile foundation 25, thereby adjusting the angle of the pile foundation 25 so that its verticality meets the construction requirements.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
