[0035] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it according to the description in the specification.

[0036] It should be understood that terms such as "having", "comprising" and "including" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0037] As Figure 1 shown, the present invention provides a pipe pile verticality detection device, including: a strip board 1 having two connecting ends 120, which is used to surround the outside of the pipe pile 7, and the two connecting ends 120 are connected by a fixing part 2; a positioning part arranged inside the strip board 1, which is used to contact the outside of the pipe pile 7 and position the strip board 1, so that the axis of the annular strip board 1 coincides with the axis of the pipe pile 7; a verticality detector 3, which is movably arranged outside the strip board 1.

[0038] Surround the strip board 1 outside the pipe pile 7, and then position the position of the strip board 1 through the positioning part, so that the axis of the annular strip board 1 can coincide with the axis of the pipe pile 7, and then fix the two connecting ends 120 through the fixing part 2 to stably fix the strip board 1 outside the pipe pile 7;

[0039] This enables the position of the verticality detector 3 on the strip board 1 to be quickly positioned as well, so that when the verticality detector 3 performs verticality detection, the verticality of the axis of the pipe pile 7 can be accurately measured; moreover, when the pipe pile 7 is being constructed, the surrounding position of the strip board 1 does not affect the hammering of the pipe pile 7, and it is not necessary to align the position of the verticality detector 3 after each hammering, which is convenient to use.

[0040] As Figure 2 shown, in one embodiment, a plurality of mounting grooves 110 are arranged on the inner side of the strip board 1. The plurality of mounting grooves 110 are at least arranged in upper and lower two layers, and the mounting grooves 110 in each layer are evenly spaced along the length direction of the strip board 1;

[0041] The positioning part includes: a plurality of contact bodies 4 for contacting the outer side of the pipe pile 7, and the contact bodies 4 are arranged in the mounting grooves 110.

[0042] The contact bodies 4 are arranged in upper and lower two layers. When the strip board 1 is surrounded on the outer side of the pipe pile 7, if there is a deviation between the axis of the annular strip board 1 and the axis of the pipe pile 7, the contact pressures between the upper and lower corresponding contact bodies 4 and the pipe pile 7 will be different. Therefore, the contact bodies 4 arranged in upper and lower two layers can detect the contact pressure on the pipe pile 7, thereby positioning the strip board 1, and further ensuring the accuracy of the position of the verticality detector 3 and improving the accuracy of verticality detection.

[0043] Furthermore, a pressure sensor is provided in the direction perpendicular to the side surface of the strip board 1 on the contact body 4, and the pressure sensor is used to detect the contact pressure between the contact body 4 and the outer side of the pipe pile 7.

[0044] When the strip board 1 is surrounded on the outer side of the pipe pile 7, it is detected by the plurality of pressure sensors of the positioning part whether the axis of the annular strip board 1 coincides with the axis of the pipe pile 7; if not, the strip board 1 is adjusted. If so, the average value of the plurality of pressure sensors is obtained as the locking force detection value. When the locking force detection value reaches the set locking force, the two connection ends 120 are connected by the fixing part 2.

[0045] The plurality of pressure sensors can be remotely communicatively connected to the control terminal. When detecting whether the axis of the annular strip board 1 coincides with the axis of the pipe pile 7, the control terminal can obtain the corresponding detection information to prompt the operator.

[0046] Among them, the locking force is set as follows: when the static friction force generated between the positioning part and the pipe pile 7 is greater than the up-and-down vibration acting force generated by the pipe pile 7 under the maximum hammering force on the strip board 1, the corresponding locking force; this is because during the construction of the pipe pile 7, the strip board 1 will be subjected to up-and-down vibration, and the vibration will cause the position of the strip board 1 fixed on the outside of the pipe pile 7 to shift, which will affect the detection accuracy of the verticality detector 3. Therefore, during the installation of the strip board 1, the locking force of the strip board 1 can be detected through the positioning part to prevent the strip board 1 from moving due to vibration; of course, even if the position of the strip board 1 shifts, it is also possible to detect whether the axis of the strip board 1 surrounding the ring coincides with the axis of the pipe pile 7 through multiple pressure sensors of the positioning part to adjust the position of the strip board 1.

[0047] Detecting whether the axis of the strip board 1 surrounding the ring coincides with the axis of the pipe pile 7 through multiple pressure sensors of the positioning part includes:

[0048] Taking two pressure sensors at corresponding positions in the upper layer and the lower layer as a group, and obtaining the pressure difference between the two pressure sensors in each group;

[0049] Judging whether the pressure difference is within the set range. If the pressure difference of at least one group of pressure sensors is not within the set range, then there is a deviation between the axis of the strip board 1 surrounding the ring and the axis of the pipe pile 7. If the pressure difference of each group of pressure sensors is within the set range, then the axis of the strip board 1 surrounding the ring coincides with the axis of the pipe pile 7.

[0050] Through the above detection method, the positioning of the installation position of the strip board 1 can be realized and adjusted in time, so that the axis of the strip board 1 surrounding the ring coincides with the axis of the pipe pile 7, thereby ensuring the accuracy of the verticality detection of the axis of the pipe pile 7 by the verticality detector 3, improving the construction quality of the pipe pile 7, and thus ensuring the structural bearing capacity of the pile slab bridge.

[0051] Such as Figure 4 and Figure 5 shown, in an embodiment, the contact body 4 includes: a contact block 410 and a support body 420. A space area for installing the support body 420 is provided inside the contact block 410; the inner side of the contact block 410 is used to contact the outside of the pipe pile 7, and installation blocks 5 are respectively provided at both outer ends of the contact block 410, and the installation blocks 5 are connected in the installation groove 110; the pressure sensor is arranged on the inner side or the outer side of the contact block 410; under the action of an external force, the inner side and the outer side of the contact block 410 can move relatively in the axial direction of the pipe pile 7.

[0052] The contact block 410 is elastic as a whole, the mounting block 5 is made of a hard material, a first permanent magnet is provided on the outer side or the bottom side of the mounting block 5, and a second permanent magnet that adsorbs to the first permanent magnet is provided at the corresponding position of the mounting groove 110;

[0053] As Figure 7 shown, the mounting groove 110 on the upper layer of the strip board 1 penetrates the upper side of the strip board 1, and the mounting groove 110 on the lower layer penetrates the lower side of the strip board 1. When installing, first install the support body 420 into the space area of the contact block 410, and then insert the contact body 4 from the opening of the mounting groove 110. Then, the contact body 4 and the mounting groove 110 are fixed by the mutual adsorption of the first permanent magnet and the second permanent magnet. Of course, the two can also be fixed by a clamping method.

[0054] The support body 420 can be disassembled, so as to facilitate the replacement of the support body 420 to change the support elasticity of the contact body 4.

[0055] As Figure 6 shown, the contact block 410 includes: an inner plate 411 for contacting the pipe pile 7, an outer plate 412 provided in the mounting groove 110, an upper plate 413 for connecting the upper ends of the inner plate 411 and the outer plate 412, and a lower plate 414 for connecting the lower ends of the inner plate 411 and the outer plate 412. A space area is formed between the inner plate 411, the outer plate 412, the upper plate 413 and the lower plate 414; the mounting blocks 5 are provided at both ends of the outer plate 412, and limiting blocks 415 for restricting the movement of the support body 420 are provided at both ends of the space area.

[0056] A hard contact plate can be provided on the side of the inner plate 411 that contacts the pipe pile 7, or a contact plate for increasing the contact friction can be provided;

[0057] The support body 420 is inserted from one side of the space area, and after squeezing the limiting block 415 with elastic deformation ability on this side, it is inserted into the interior of the space area, and then is restricted in the space area by the limiting blocks 415 on both sides of the space area;

[0058] When fixing the strip board 1, the inner plate 411 is squeezed by the pipe pile 7, so that both the support body 420 and the outer plate 412 are squeezed. At this time, the pressure sensor can detect the change in pressure, so as to realize the positioning and locking of the strip board 1;

[0059] After the strip board 1 is arranged around the pipe pile 7, when the pipe pile 7 is under construction, the strip board 1 is subjected to up-and-down vibration forces. Since the inner board 411 is in close contact with the pipe pile 7, the vibration will be first transmitted to the inner board 411. The upper board 413 and the lower board 414 with elastic deformation ability will deform under the vibration, which will cause a relative movement trend between the inner board 411 and the outer board 414. Under the elastic recovery action of the upper board 413 and the lower board 414, the vibration transmitted to the outer board 414 can be reduced, thereby preventing the strip board 1 connected to the outer board 414 from generating position offset. Through multiple contact bodies 4, the influence of vibration on the strip board 1 can be reduced, thus ensuring the accuracy of the position of the strip board 1.

[0060] As Figure 7 shown, in one embodiment, two connecting ends 120 extend from both ends of the strip board 1 along its length direction. A receiving opening 130 is provided above one connecting end 120 and below the other connecting end 120. When the strip board 1 forms a ring, one connecting end 120 can be located at the receiving opening 130 on one side of the other connecting end 120.

[0061] When the strip board 1 forms a ring, the two connecting ends 120 are staggered up and down, and then the two connecting ends 120 can be fixed by the fixing part 2; the length of the connecting end 120 is equal to the length of the receiving opening 130. The length of the connecting end 120 can be set according to the circumference of the pipe pile 7, that is, the minimum circumference of the strip board 1 forming a ring should be less than the circumference of the pipe pile 7, and the maximum circumference of the strip board 1 forming a ring should be greater than the circumference of the pipe pile 7.

[0062] Furthermore, as Figure 3 shown, a contact body 4 is also provided inside the connecting end 120 to provide support for the installation and fixation of the strip board 1.

[0063] As Figure 2 、 Figure 7 and Figure 9 shown, in one embodiment, the fixing part 2 includes: a fixing plate 210, and a first sliding groove 121 for the fixing plate 210 to slide is provided on the connecting end 120; a plurality of first locking holes 122 are arranged along the length direction on the outer side of the connecting end 120. Second locking holes 211 corresponding to the first locking holes 122 of the two connecting ends 120 are provided on the fixing plate 210, and the first locking holes 122 and the second locking holes 211 are connected by a locking member 220.

[0064] Both the upper and lower ends of the fixing plate 210 are provided with first sliders corresponding to the first sliding grooves 121, so that the fixing plate 210 can slide within the first sliding grooves 121, enabling the vertically arranged second locking holes 211 to respectively align with at least one of the multiple first locking holes 122 on the two connecting ends 120, and then being fixedly installed through the locking member 220, thereby fixing the strip plate 1 on the outer side of the pipe pile 1.

[0065] Further, the first locking hole 122 is a threaded hole, the second locking hole 211 is a through hole, and the locking member 220 is a bolt;

[0066] Alternatively, both the first locking hole 122 and the second locking hole 211 are snap - connection holes, and the locking member 220 is a snap - connection piece that cooperates with the snap - connection holes.

[0067] As Figure 2 and Figure 9 shown, in one embodiment, the perpendicularity detector 3 is movably arranged on the strip plate 1 through the support plate 6; second sliding grooves 140 are respectively provided on the upper and lower sides of the strip plate 1, the support plate 6 is slidably arranged within the second sliding grooves 140, and the outer side of the support plate 6 is used for installing the perpendicularity detector 3.

[0068] Both the upper and lower ends of the support plate 6 are provided with second sliders corresponding to the second sliding grooves 140, so that the support plate 6 can slide within the second sliding grooves 140, and the perpendicularity detector 3 is installed on the support plate 6 by means of bolt connection; the perpendicularity detector 3 can be any instrument that can be installed on the support plate 6 and detect the perpendicularity of the pipe pile 7.

[0069] In one embodiment, the strip plate 1 that encloses to form a ring is at least divided into four detection regions; when detecting the perpendicularity of the pipe pile 7, the perpendicularity detector 3 respectively detects the perpendicularity of the pipe pile 7 within the four detection regions.

[0070] To further improve the detection accuracy, the strip plate 1 that encloses to form a ring can be divided into four detection regions, such as Figure 10 the four detection regions A, B, C, and D divided by the center line shown, then during detection, the perpendicularity detector 3 can be respectively placed within the four detection regions for detection, and the average value is taken as the perpendicularity detection result; in addition, the detection points within the four detection regions can be one or more.

[0071] A method for detecting the perpendicularity of a pipe pile, using the pipe pile perpendicularity detection device of the present invention, includes:

[0072] When the strip plate 1 is arranged around the outer side of the pipe pile 7, it is detected by the multiple pressure sensors of the positioning part whether the axis of the strip plate 1 that encloses to form a ring coincides with the axis of the pipe pile 7;

[0073] If not, adjust the strip board 1 until the axis of the strip board 1 forming a ring coincides with the axis of the pipe pile 7; if so, obtain the average value of multiple pressure sensors as the locking force detection value. When the locking force detection value reaches the set locking force, connect the two connecting ends 120 through the fixing part 2.

[0074] The strip board 1 forming a ring is at least divided into four detection areas, and the verticality detector 3 is used to detect the verticality of the pipe pile 7 in the four detection areas respectively.

[0075] Among them, the set locking force is: the static friction force generated between the positioning part and the pipe pile 7, which is greater than the locking force corresponding to the up-and-down vibration acting force generated by the pipe pile 7 when receiving the maximum hammering force on the strip board 1. This is because during the construction of the pipe pile 7, the strip board 1 will be subjected to vibration in the up-and-down direction, and the vibration will cause the position of the strip board 1 fixed outside the pipe pile 7 to shift, which will affect the detection accuracy of the verticality detector 3. Therefore, during the installation of the strip board 1, the locking force of the strip board 1 can be detected through the positioning part to prevent the strip board 1 from moving due to vibration. Of course, even if the position of the strip board 1 shifts, it is also possible to detect whether the axis of the strip board 1 forming a ring coincides with the axis of the pipe pile 7 through multiple pressure sensors of the positioning part to adjust the position of the strip board 1.

[0076] Such as Figure 10 The four detection areas A, B, C, and D divided by the center line shown. When detecting, the verticality detector 3 can be placed in the four detection areas respectively for detection, and then the average value is taken as the verticality detection result.

[0077] Through the above method, the position of the verticality detector 3 on the strip board 1 can also be quickly positioned, so that when the verticality detector 3 detects, the verticality of the axis of the pipe pile 7 can be accurately measured; moreover, during the construction of the pipe pile 7, the surrounding position of the strip board 1 does not affect the hammering of the pipe pile 7, and it is not necessary to find the position of the verticality detector 3 after each hammering, which is convenient to use; furthermore, the vibration effect generated by the construction of the pipe pile 7 on the strip board 1 will not cause the strip board 1 to shift in position, reducing the adjustment of the position of the strip board 1.

[0078] Furthermore, detecting whether the axis of the strip board 1 forming a ring coincides with the axis of the pipe pile 7 through multiple pressure sensors of the positioning part includes:

[0079] Two pressure sensors at corresponding positions in the upper layer and the lower layer are taken as a group, and the pressure difference between the two pressure sensors in each group is obtained.

[0080] Determine whether the pressure difference is within the set range. If the pressure difference of at least one set of pressure sensors is not within the set range, then there is a deviation between the axis of the strip 1 forming a ring and the axis of the pipe pile 7. If the pressure difference of each set of pressure sensors is within the set range, then the axis of the strip 1 forming a ring coincides with the axis of the pipe pile 7.

[0081] Through the above detection method, the positioning of the installation position of the strip 1 can be realized and adjusted in time, so that the axis of the strip 1 forming a ring coincides with the axis of the pipe pile 7, thereby ensuring the accuracy of the perpendicularity detection of the axis of the pipe pile 7 by the perpendicularity detector 3, improving the construction quality of the pipe pile 7, and thus ensuring the structural bearing capacity of the pile bridge.
