Description

Technical Field

[0001] This invention relates to the field of steel pipe pile measurement, and in particular to a method for measuring the positioning parameters of underwater steel pipe piles. Background Technology

[0002] Underwater steel pipe piles are widely used in the construction of water-related structures such as bridge foundations, port terminals, and cross-sea tunnels. The accuracy of their positioning parameters directly determines the overall stability and load-bearing capacity of the structure, and is a key link in the quality control of engineering construction.

[0003] Currently, underwater steel pipe pile positioning measurements mainly rely on optical measuring equipment such as total stations. However, these devices are limited by factors such as water refraction, water turbidity, and water depth, making it impossible to penetrate the water and directly obtain the true position data of the underwater steel pipe piles, resulting in significant measurement errors. Traditional measurement methods require underwater calibration by divers or coarse adjustments using simple hoisting devices, which are not only complex and inefficient but also pose safety risks during diving operations and make it difficult to accurately collect the positioning parameters of the steel pipe piles. Furthermore, existing measuring devices lack flexible adjustment mechanisms to adapt to different pile spacings and stable underwater fixing structures, further exacerbating the problem of insufficient measurement accuracy.

[0004] Therefore, there is an urgent need for a technical solution that can avoid water interference and achieve accurate measurement of underwater steel pipe pile positioning parameters, solving the core problems of limited applicability of total stations, low measurement accuracy, and poor operational safety in existing technologies. Summary of the Invention

[0005] The main objective of this invention is to provide a method for measuring the positioning parameters of underwater steel pipe piles, which solves the problem that traditional optical measuring equipment cannot avoid water interference and achieves accurate measurement of the positioning parameters of underwater steel pipe piles.

In the preferred embodiment, the top of the adsorption shell is also provided with multiple evenly distributed limiting posts, each of which is equipped with a lifting cylinder. The output shaft end of the lifting cylinder is equipped with a lifting plate.

Furthermore, the use of dual winches for hoisting enhances operational safety, providing a reliable technical means for underwater steel pipe pile positioning and measurement, significantly ensuring the construction quality and efficiency of water-related projects.

The gear 105 meshes with the rack 105, and the rotation of the gear 105 causes the telescopic rod 103 to extend and retract for fine adjustment to adjust the spacing of the measuring device.

[0021] In the preferred embodiment, in step S3, the lifting assembly 2 includes a lifting ring seat 201, which is arranged on the outside of the adsorption assembly 5.

The hydraulic motor 3209 can make the docking assembly 4 swing left and right at a certain angle to further align the steel pipe pile 6.

[0022] In the preferred embodiment, in step S3, the docking component 4 includes a trumpet-shaped docking flare 401, and the conical surface of the docking flare 401 is provided with a plurality of evenly distributed hollow gaps 402. The docking assembly 4 has a positioning cone 403 inside, which is used to connect with the inner control of the steel pipe pile 6.

[0023] In the preferred embodiment, in step S4, the adsorption assembly 5 includes an adsorption shell 501, and the adsorption shell 501 is provided with multiple adsorption cylinders 503. The output shaft end of the adsorption cylinder 503 is provided with an annular adsorption magnetic ring 505. Multiple pressure sensors are also evenly distributed below the adsorption magnetic ring 505. The adsorption magnetic ring 505 is used to adsorb the top surface of the steel pipe pile 6.

[0024] In the preferred embodiment, in step S4, after the docking plane 404 of the docking component 4 is attached to the top surface of the steel pipe pile 6, the adsorption cylinder 503 is activated to move the adsorption magnetic ring 505 downward to attach and adsorb to the top surface of the steel pipe pile 6. The pressure sensor below the magnetic adsorption ring 505 transmits pressure data to the workers on shore to indicate that the docking assembly 4 and the steel pipe pile 6 have been temporarily fixed. The adsorption housing 501 is also equipped with a hydraulic station 507 inside, which is used to provide power to multiple hydraulic motors. The top of the adsorption housing 501 is also equipped with a hinge seat 506, which is used to connect to the measuring component 3.

[0025] In the preferred embodiment, in step S5, the measuring component 3 includes a measuring base 301, a plurality of evenly distributed connecting rods 302 are provided above the measuring base 301, and a measuring top plate 303 is provided on the top of the connecting rods 302. The measuring top plate 303 is used to install a GPS locator 304. The bottom of the measuring base 301 is provided with a hinge rod 305, which is used to connect to the hinge seat 506 in a omnidirectional swing. Between the bottom of the hinge rod 305 and the top of the adsorption shell 501, there are also an adjusting cylinder 1 306 and an adjusting cylinder 2 314. The adjusting cylinder 1 306 and the adjusting cylinder 2 314 are used to adjust the verticality of the GPS locator 304 of the measuring component 3. In the preferred embodiment, the top of the adsorption shell 501 is also provided with a plurality of evenly distributed limiting posts 308, and the limiting posts 308 are provided with lifting cylinders 312. The output shaft end of the lifting cylinders 312 is provided with a lifting plate 313. The lifting cylinders 312 are used to lift upward together to temporarily keep the measuring component 3 fixed and unadjustable. A separate monitoring sleeve 307 is provided between the first regulating cylinder 306 and the second regulating cylinder 314 and the hinge rod 305. The monitoring sleeve 307 is provided with a rolling ball 309. The middle section of the monitoring sleeve 307 is an insulating part 310. Both ends of the insulating part 310 are provided with sensing parts 311. The sensing part 311 on one side is used to control the lifting of the first regulating cylinder 306 and the second regulating cylinder 314, and the sensing part 311 on the other side is used to control the retraction of the first regulating cylinder 306 and the second regulating cylinder 314.

[0026] In the preferred embodiment, in step S5, the measuring component 3 is used to fine-tune the perpendicularity of the measuring component 3 through the monitoring sleeve 307 and the ball bearing 309. The ball bearing 309 is rolled in the monitoring sleeve 307. The adjusting cylinder 1 306 and the adjusting cylinder 2 314 are arranged at a 90-degree angle to the circumferential surface. The adjusting cylinder 1 306 and the adjusting cylinder 2 314 adjust the Y-axis and X-axis directions of the measuring component 3 respectively. The tops of the first adjusting cylinder 306 and the second adjusting cylinder 314 are spherically hinged to the measuring base 301, and the bottoms of the first adjusting cylinder 306 and the second adjusting cylinder 314 are spherically hinged to the adsorption shell 501. In step S1, the crane uses two independent winches to control two independent slings 7 connected to the lifting ring 206. Example 2 Further explanation in conjunction with Example 1, such as Figure 1-10 The structure shown illustrates a method for measuring underwater steel pipe pile positioning parameters, implemented as follows: The measuring device is pre-assembled on the shore. The telescopic rod 103 of the telescopic component 1 is in its initial retracted state, or the spacing can be adjusted in advance according to the pre-designed steel pipe pile spacing. The lifting seat 208 of the lifting component 2 is located on the lifting guide rod 203. The positioning cone 403 of the docking component 4 remains vertical. The adsorption magnetic ring 505 of the adsorption component 5 is housed in the adsorption groove 504. The adjusting cylinders 306 and 314 of the measuring component 3 are in the neutral position. The lifting cylinder 312 is retracted. The GPS locator 304 completes debugging and calibration. The two independent winches of the crane are connected to the two lifting rings 206 at the top of the lifting top plate 204. The hydraulic station 507 inside the adsorption shell 501 is started and preheated, providing stable power to the hydraulic motors 102, 205, 309, and each cylinder.

[0027] The operator controls the crane's double winch through the control console to simultaneously release two independent slings 7, and smoothly hoist the measuring device to the top of the first target steel pipe pile 6, keeping the device horizontal to avoid component collision, until the lower surface of the device is about 50cm away from the top of the steel pipe pile 6 and then stops lowering.

[0028] Based on the preset distance data between the first steel pipe pile 6 and the adjacent pile to be measured, an adjustment command is sent to the hydraulic motor 102. After the hydraulic motor 102 starts, it drives the gear 105 to rotate. The gear 105 meshes with the telescopic racks 104 on both sides, driving the telescopic rod 103 to extend and retract axially along the telescopic sleeve 101. This, in turn, drives the lifting components 2, adsorption components 5, and docking components 4 at both ends to move synchronously until the center distance between the two docking components 4 matches the design distance. Then, the hydraulic motor 102 stops working, and the telescopic rod 103 is fixed by the hydraulic locking mechanism.

[0029] After confirming the spacing is correct, control the double winch to slowly lower the sling 7, and the measuring device descends at a uniform speed. When the flared opening 401 of the docking assembly 4 approaches the top of the steel pipe pile 6, start the hydraulic motor 205, whose output shaft drives the lifting screw 207 to rotate, so that the lifting seat 208 slides vertically along the lifting guide rod 203, driving the adsorption assembly 5 and the docking assembly 4 to finely adjust their height; if there is a horizontal deviation, start the hydraulic motor 209, so that the docking assembly 4 swings left and right around the end of the telescopic rod 103 until the conical surface of the docking opening 401 covers the top of the steel pipe pile 6.

[0030] The slotted gap 402 on the flared opening 401 reduces water resistance and lateral water flow impact. The hydraulic motor 205 is then finely adjusted so that the mating plane 404 contacts the top surface of the steel pipe pile 6. The positioning cone 403 is inserted into the inner hole of the steel pipe pile 6 to achieve coaxial fit. Subsequently, the hydraulic motor 205 and the hydraulic motor 209 stop working.

[0031] After docking is completed, the adsorption cylinder 503 of the adsorption assembly 5 is activated, and its piston rod extends downward, pushing the adsorption magnetic ring 505 down along the adsorption slide 504. The piston ring on the outside of the adsorption magnetic ring 505 ensures the movement is sealed. When the lower surface of the adsorption magnetic ring 505 is in complete contact with the top surface of the steel pipe pile 6, a strong magnetic force is generated for adsorption. The pressure sensor below collects the contact pressure data in real time and transmits it to the onshore control console. When the pressure reaches the preset threshold, the control console issues a "fixing complete" prompt. The adsorption cylinder 503 remains extended, realizing the temporary fixation of the measuring device and the steel pipe pile 6.

[0032] After fixing, start the verticality adjustment program. Adjusting cylinder 306 and adjusting cylinder 314 are arranged at a 90° angle, corresponding to the Y-axis and X-axis directions respectively. The top of both are spherically hinged to the measuring base 301, and the bottom is spherically hinged to the adsorption shell 501.

[0033] The ball bearing 309 inside the monitoring sleeve 307 rolls as the measuring component 3 tilts. When it contacts one end of the sensing part 311, the corresponding adjustment cylinder lifts up; when it contacts the other end of the sensing part 311, the cylinder retracts, and the horizontal state is corrected through closed-loop adjustment.

[0034] When the ball bearing 309 stops in the insulating part 310 area in the middle of the monitoring sleeve 307, it indicates that the GPS locator 304 is vertical. At this time, the lifting cylinder 312 in the limit column 308 is activated, and the piston rod extends to drive the lifting plate 313 to press against the measuring base 301, temporarily fixing the measuring component 3 to avoid the influence of water flow disturbance.

[0035] GPS locator 304 then collects data such as plane coordinates, verticality deviation, and pile top elevation for 10 seconds to ensure stability. The data is automatically stored and uploaded to the onshore database, and the measurement of the first steel pipe pile is completed.

[0036] After the first pile measurement is completed, the devices are unlocked in sequence: the lifting cylinder 312 retracts, and the lifting plate 313 disengages from the measuring base 301; the adjusting cylinder 306 and the adjusting cylinder 314 are reset to the center position; the adsorption cylinder 503 retracts, and the adsorption magnetic ring 505 rises and disengages from the top surface of the steel pipe pile 6; the hydraulic motor 205 rotates in the opposite direction, driving the lifting seat 208 to rise 50cm, and the docking assembly 4 separates from the steel pipe pile 6; the hydraulic motor 102 rotates in the opposite direction, and the telescopic rod 103 retracts to the initial spacing.

[0037] Then, the double winch of the crane is operated to move the measuring device horizontally to the top of the next target steel pipe pile 6, and the hoisting and positioning process is repeated. If the spacing is consistent with the previous pile, the spacing adjustment is skipped. Otherwise, the spacing of the docking component 4 is adjusted according to the aforementioned steps. Then, the steps of precise lowering, docking, adsorption fixation, verticality adjustment and parameter acquisition are repeated in sequence.

[0038] Following the cycle of unlocking → translation → spacing adjustment (as needed) → docking → fixing → measurement, the positioning parameters of all steel pipe piles 6 to be measured are collected in sequence. After all measurements are completed, the crane is used to lift the measuring device onto the transport ship, the hydraulic station 507 is turned off, all telescopic, lifting, and adjusting components are retracted to their initial state, and the docking assembly 4 and the magnetic adsorption ring 505 are cleaned and maintained to complete the entire measurement operation.
