Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a steel pipe pile rapid positioning device and a construction method. Background Art

[0002] During bridge construction, temporary trestles are usually required to transport materials, equipment, and personnel. The lower structure of the trestles is generally made of steel pipe piles. However, due to the uneven riverbed, the impact of water flow and wind speed, if lifting equipment is directly used to lift the steel pipe piles for pile foundation construction, the verticality and positioning accuracy cannot be guaranteed, which will cause the steel trestles to become unstable and collapse, causing irreparable losses to the construction safety of the project and the personal safety of the construction workers. Therefore, it is necessary to use a guide frame system to convert water positioning to land positioning to avoid the influence of external factors on the positioning and verticality of the steel pipe piles.

[0003] The existing steel pipe pile guide frame needs to use lifting equipment to continuously adjust the position of the guide frame during installation and positioning, which makes positioning difficult and the positioning accuracy is low and inaccurate. During the construction process, the steel pipe piles need to be hoisted using large lifting equipment, and the verticality needs to be observed manually using a total station during the pile sinking process. When deviation or tilt is found, timely adjustment is required. During the piling process, only one steel pipe pile can be driven at a time. Such operation not only has an unobvious pile-forming effect, but also causes a slow construction process and high economic costs. Summary of the Invention

The limited rotation assembly 32 includes a rotating handle 321, a first rubber clamp 322, a second rubber clamp 323, two limiting pieces 324, a threaded rod 325 and a cross screw handle 326. The rotating handle 321 is rotatably connected to the pipe mouth of the connecting stand pipe 313. Multiple first rubber clamps 322 are fitted on the arc surface of the rotating handle 321, and multiple second rubber clamps 323 are fitted on the inner annular surface of the connecting stand pipe 313. The second rubber clamp 323 is alternately distributed with the first rubber clamp 322. The two limiting pieces 324 are respectively fixed at both ends of the rotating handle 321. The threaded rod 325 is fixedly connected to the surface of the limiting piece 324. The cross screw handle 326 is fixedly connected to the end of the threaded rod 325 away from the rotating handle 321 through a plate. The cross screw handle 326 presents a "cross" plate structure;The clamping assembly 33 includes a traction plate 331, a wire sleeve 332, a clamping block 333, a mounting groove 334 and a rubber gasket 335. The traction plate 331 is fixed on the opposite surface of the limiting piece 324 facing the pinch plate 311.

Rubber sheets are provided on the surfaces of the sliding I-beams 492 to increase friction.

[0081] A method for quickly positioning a steel pipe pile is provided, which uses the aforementioned device for quickly positioning a steel pipe pile. The method comprises the following specific steps:

[0082] S1: Assemble the device and perform positioning during the assembly process. This step is the preparation and installation positioning;

[0083] S2: The positioning mechanism fixes the steel pipe pile and transports it to the predetermined pile position. This step is to transport the steel pipe pile.

[0084] S3: Control the verticality of the steel pipe pile so that it always remains vertical. This step realizes the control of the verticality of the steel pipe pile;

[0085] S4: Vibrate the steel pipe pile to ensure that it sinks vertically. This step allows the steel pipe pile to sink.

[0086] Furthermore, the specific steps of S1 are: first weld and assemble the Bailey beam guide frame, use the crawler crane to hoist the Bailey beam guide frame as a whole, connect the end of the guide frame with the front end of the trestle that has been laid by adjusting the guide wheel, calibrate and lay the sliding plate with steel pipe pile positioning holes opened in advance on the concave slide rail, and assemble the steel pipe pile limiting device on its upper surface. According to the design requirements, during the hoisting process using the crawler crane, first use the trestle that has been laid as a rough positioning guide for the steel pipe piles to be constructed, and then fine-tune the Bailey beam guide frame by adjusting the guide wheel to complete the precise positioning of the steel pipe piles.

[0087] Furthermore, the specific steps of S2 are: changing the height of the regulating bolts around the limit box to make the limit box in a horizontal state, adjusting the sliding plate to the front end of the trestle that has been laid, placing the steel pipe pile vertically in the steel pipe positioning hole, and adjusting the table jack to make the arc locator fix the steel pipe pile, controlling the sliding plate to drive the fixed steel pipe pile to slide to the predetermined pile position, using the track groove at the bottom of the concave slide rail to fine-tune the position, and finally lowering the wedge-shaped clip to fix the sliding plate.

[0088] Furthermore, the specific steps of S3 are: when the steel pipe pile slides to the specified position, the steel pipe pile is clamped by adjusting the sliding I-beam on the vertical frame, and the upper surface jack is used to ensure that the pile is always kept in a vertical state during the pile sinking process.

[0089] Furthermore, the specific steps of S4 are as follows: With the steel pipe pile limiter and sliding I-beam ensuring the verticality of the steel pipe pile, use a crawler crane in conjunction with a vibratory hammer to drive the steel pipe pile. During the driving process, the sliding I-beam and the hydraulic pressure of the hydraulic jack should be adjusted to adjust the verticality of the pile. During the vibration sinking process, if the verticality deviation of the pile is found to be too large, measures such as extending the vibration retention time and alternating lifting and vibration sinking are adopted to liquefy the soil around the pile and ensure that the steel pipe pile sinks vertically.

[0090] Finally, after a row of steel pipe piles are sunk, the sliding plate is removed, and the distribution beams, main beams and bridge deck system are laid. Finally, the construction of the next trestle is started and the above steps are repeated.

[0091] Working process: The U-shaped groove 315 and the Bailey beam 21 clamping handle are reinforced by bolts, and the cross screw handle 326 is rotated, and the threaded rod 325 rotates accordingly. When it needs to be fixed to the trestle 1, the cross screw handle 326 is rotated to make the thread sleeve 332 move vertically toward each other, driving the traction plate 331 to move toward each other, and then driving the clamping block 333 to move toward each other. When it is necessary to convert the rotation angle of the Bailey beam 21, the cross screw handle 326 is rotated to make the clamping block 333 release the trestle 1, and the Bailey beam 21 is rotated for fine adjustment, and then the above operation is repeated for precise positioning. When the steel pipe pile moves to the specified position, the sliding I-beam 492 is adjusted to clamp the steel pipe pile to ensure that the steel pipe pile is always vertical. The crawler crane cooperates with the vibrating hammer to hit the steel pipe pile. When the steel pipe pile deflects greatly, the soil around the pile is liquefied by extending the vibration time, alternating pulling up and vibrating sinking, etc., to ensure that the steel pipe pile sinks vertically.
