Description

Technical Field

[0001] The present invention belongs to the technical field of pipe pile connection, and more specifically, relates to a rapid connection positioning device for pipe piles and its usage method. Background Art

[0002] In the fields of civil engineering, port construction, high-rise building construction, and bridge construction, pipe piles are widely used due to their excellent performance. Pipe piles have significant advantages such as high strength, corrosion resistance, and convenient construction, making them an indispensable component in modern engineering construction. Especially in the case of bearing heavy loads and complex environmental conditions, the use of pipe piles can effectively improve the overall stability and durability of the structure. However, the connection quality of pipe piles is directly related to the stability and safety of the entire structure. Therefore, the reliability of the connection process has become a key technical difficulty during construction.

[0003] In the prior art, a Chinese patent with the publication number CN116145656A discloses a rapid pipe pile connector, which includes embedded parts, bushings, bite petals, elastic rings, snap rings, compression springs, and connection columns. There are two embedded parts, and the embedded parts are in a cylindrical shape. The two embedded parts are arranged opposite to each other, and bushings are fixedly installed at the opposite openings of the two embedded parts. A number of bite petals are movably installed inside the bushings. All the bite petals are equally angularly divided by a hollow cylinder, and all the bite petals together form a bite body. A number of inner bite tooth patterns are provided on the inner wall of the bite body. An elastic ring is sleeved outside the bite body, and an embedding groove is provided on the outer wall of the bite body. The elastic ring is embedded in the embedding groove. One end of the inner wall of the bushing includes a limiting ring.

[0004] The above patent makes it difficult for the bite petals to separate from the bushing by setting the snap ring inside the bushing, and it is not easy to form too many mutually separated parts when disassembling the embedded parts, which is convenient for reassembling the embedded parts. However, it still does not solve some problems in the connection of pipe piles in existing engineering construction: (1) When connecting the hoisted pipe pile to the embedded pipe pile, the inclination of the hoisted pipe pile is a factor that cannot be ignored; if the inclination of the hoisted pipe pile does not meet the standard, even if the connection stability of the embedded parts is improved, it is difficult to ensure the verticality and alignment accuracy of the entire pipe pile structure, thus affecting the overall quality and safety of the project; (2) The pipe pile connection device designed in the above patent is only suitable for pipe piles of a single pipe diameter, which limits its scope of application in practical applications. Especially in complex engineering construction, it is often necessary to deal with the connection requirements of pipe piles of different pipe diameters. The applicability of a single pipe diameter is difficult to meet the diverse design and construction requirements, thus reducing the construction efficiency and the flexibility of the project. Summary of the Invention

During the use process, by adjusting the length of the telescopic rod 33, the two support plates are respectively stably sleeved outside the two pipe piles, and the device is firmly installed on the two pipe piles in cooperation with the caliper assembly 34, so as to achieve quick positioning and adapt to pipe piles of various sizes; secondly, through the setting of the measuring unit 4, the inclination angle of the second pipe pile 2 can be conveniently measured, deviations can be detected and corrected in time, and construction hidden dangers caused by the inclination of the pipe pile can be avoided; in addition, through the leveling unit 5, the stability of the device is further improved, the accuracy of the measurement data is ensured, and thus the construction efficiency and quality are improved.

[0047] Specifically, asFigures 1 to 5 As shown, in the positioning unit 3, the lower support plate 31 and the upper support plate 32 are both annular support plates; corresponding slide rails 301 are evenly arranged on the upper end surface of the lower support plate 31 and the bottom end surface of the upper support plate 32; a plurality of arc-shaped through holes 302 are evenly arranged on the lower support plate 31 along its circumferential direction.

[0049] Further, the telescopic rod 33 has at least three, and includes: an inner tube 331 with its bottom end connected to the lower support plate 31, an outer tube 332 sleeved outside the inner tube 331 and with its upper end connected to the upper support plate 32, and a first bolt 333 for positioning and fixing the outer tube 332 to the outside of the inner tube 331. It can be understood that one end of the first bolt 333 passes through the outer tube 332 and contacts the outer surface of the inner tube 331, and by rotating the first bolt 333, the outer tube 332 can be positioned and fixed at a suitable position on the inner tube 331.

[0050] Further, the caliper assembly 34 includes: a triangular caliper 341, a chute 342 provided at the bottom end of the triangular caliper 341 and adapted to the slide rail 301, and a second bolt 343. The screw of the second bolt 343 passes through the strip-shaped through hole and the chute 342 and is rotatably connected to the triangular caliper 341, to ensure smooth sliding of the triangular caliper 341 on the slide rail 301, and at the same time realize precise positioning and fixing of the triangular caliper 341 on the slide rail 301.

[0051] In an alternative embodiment, the number of the slide rails 301 and the triangular calipers 341 is eight each, and the slide rails 301 are symmetrically arranged on the surfaces of the lower support plate 31 and the upper support plate 32 along two perpendicular axes, to ensure that the connection and positioning device is fixed to the outer sides of two pipe piles.

[0054] Specifically, as Figures 1 to 3 , Figure 6 shown, the measuring units 4 are respectively arranged at the upper end of the lower support plate 31 and the bottom end of the upper support plate 32 for measuring the inclination angle of the second pipe pile 2. The measuring unit 4 includes: a base 41, a laser level 42, a third bolt 43, a first scale 44, a second scale 45, and a third scale 46; one end of the third bolt 43 passes through the arc-shaped through hole 302 and is connected to the bottom end of the base 41; the laser level 42 is arranged in the middle of the upper end of the base 41 and is a two-line level; the first scale 44 is arranged along the inner circumferential direction of the upper surface of the lower support plate 31; the second scale 45 is arranged along the outer circumferential direction of the lower surface of the upper support plate 32, and its scale value corresponds to the scale value of the first scale 44; the third scale 46 is respectively arranged on the surfaces of the lower support plate 31 and the upper support plate 32 and is arranged on one side of the slide rail 301. During use, by making the laser emitted by the laser level 42 contact the first scale 44 and the second scale 45 respectively, it is convenient to calculate the inclination angle of the second pipe pile through the difference between the scale values of the two scales. In addition, when the inclination angle is too low, the scale value of the end of the triangular caliper 341 far from the pipe pile is recorded through each third scale 46, and combined with the overall length of the telescopic rod 33, the inclination angle of the pipe pile is further calculated, thus effectively solving the problem of low-angle measurement. At the same time, through multi-point data collection and comprehensive calculation, the accuracy and reliability of the final measurement result are ensured.

[0055] Preferably, the third scale 46 is a strip-shaped scale, which corresponds to the sliding track of the end of the triangular caliper 341 far from the pipe pile on the slide rail 301.

[0058] It should be noted that in other embodiments, other types of glass spirit levels can also be used, which are not specifically limited here, but these solutions are all within the protection scope of the present invention.

[0059] Embodiment 2

[0060] As Figure 7 shown in Figure 7 , based on Embodiment 1, Embodiment 2 of the present invention provides a method for using a pipe pile quick connection and positioning device, including the following steps:

[0061] S1: Install the laser level 42 on the base 41, and install the base 41 to the upper end of the lower support plate 31 through the arc-shaped through hole 302 and the third bolt 43. Then, adjust the foot screw 413 to keep the laser level 42 relatively horizontal with the lower support plate 31;

[0062] S2: Sleeve the connection and positioning device on the outside of the first pipe pile 1 that has been driven. Clamp the first pipe pile 1 through several triangular calipers 341 at the upper end of the lower support plate 31, and adjust the triangular calipers 341 through the first glass circular spirit level 51 to level the lower support plate 31;

[0063] S3: Adjust the overall length of the telescopic rod 33 through the first bolt 333 until the upper support plate 32 is sleeved on the outside of the second pipe pile 2. Then, press several triangular calipers 341 at the bottom end of the upper support plate 32 against the second pipe pile 2 and fix them with the second bolt 343;

[0064] S4: If the second pipe pile 2 is inclined, determine the level of the laser level 42 through the third glass circular spirit level 53, and obtain the inclination angle of the second pipe pile 2 through the difference between the first scale 44 and the second scale 45;

[0065] S5: In step S4, when the inclination angle of the second pipe pile 2 is less than the accuracy of the first scale 44 and the second scale 45, by calculating the difference in the scale values of the third scale 46 on one side of the corresponding triangular calipers 341 between the lower support plate 31 and the upper support plate 32, and combining the height difference between the bottoms of the corresponding two triangular calipers 341, obtain the inclination angle of the second pipe pile 2 through the inverse trigonometric function;

[0066] S6: If the angle of the second pipe pile 2 meets the requirements, directly proceed with the connection operation; if the angle of the second pipe pile 2 does not meet the requirements, slide several of the triangular calipers 341 on the upper support plate 32 away from the second pipe pile 2 through the slide rail 301. According to the inclination angle obtained in steps S4 and S5, adjust the angle of the second pipe pile 2 with a static pile press. After that, perform the connection operation between the first pipe pile 1 and the second pipe pile 2.

[0067] It should be noted that in step S5, there are four groups of the triangular calipers 341 and the third scales 46 corresponding to the lower support plate 31 and the upper support plate 32, and there are also four corresponding differences. Among them, the maximum value of these differences is Δd, and the ratio of this value to the height difference h between the bottoms of the two corresponding triangular calipers 341 is the vertical rate of the second pipe pile 2. Then, the inclination angle θ of the second pipe pile 2 can be obtained through the inverse trigonometric function, and this θ = arctan(Δd / h).

[0068] Other technical features are the same as those in Embodiment 1 and can achieve the same technical effects, which will not be elaborated here one by one.

[0069] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, then such directional indications are only used to explain the relative positional relationship, movement conditions, etc. between components in a certain specific posture (as shown in the drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0070] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, then such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0071] In the present invention, the term "comprise", "include" or any other variant thereof is intended to cover a non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, the elements defined by the statement "comprising..." do not exclude the presence of additional identical elements in the process, method, article or device comprising such elements.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; it is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not used to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
