Description

TECHNICAL FIELD

[0001] The present application relates to the civil engineering technical field, specifically to a double chuck large-depth H-shaped pile delivery equipment and a pile delivery method thereof. BACKGROUND

[0002] In the prior art, with the development of national economic construction, the application of H-shaped piles is also more and more common. The H-shaped pile adopts a H-shaped prefabricated component, and has reliable pile body quality, simple process, fast construction speed, small occupied area, no (low) soil compaction, no (low) noise, no slurry transportation and other environmental pollution problems, and is therefore widely used.

[0003] In the prior art, in some foundation pit construction projects, a pile driver and a pile delivery machine are needed to jointly deliver the prefabricated pile into the designed pile top position in the soil, and this process is called pile delivery.

[0004] However, the present construction project, especially the industrial project, is affected by factors such as foundation embedding depth and process requirements, and there are several different pile top elevations in a region, and the pile top elevation is more than 2 meters below the ground surface, and the relative height difference between different pile top elevations is also large. This feature determines that the pile delivery depth cannot be reduced by lowering the ground elevation during the construction process, and only the pile foundation construction can be carried out on the original ground surface (close to ±0.00).

[0005] Therefore, the problem of large-depth pile delivery arises, and the pile delivery depth is generally more than 2 meters, and the deepest one even reaches nearly 10 meters. In the case that the pile top is designed to be below the ground surface, the site is limited and cannot be excavated on a large scale, and the pile driver and traffic cannot be developed during pile driving, the pile can be driven at the present ground surface, and then the pile top is driven below the ground surface by using the pile delivery device.

[0006] However, the pile delivery equipment in the prior art cannot meet the requirements of large-depth pile delivery on the one hand, and on the other hand, the clamping of the H-shaped pile is not stable during the specific pile delivery, and the uneven friction between the H-shaped pile and the clamping mechanism will cause the relative slip between the clamping mechanism and the H-shaped pile, resulting in uneven stress of the H-shaped pile during the pile delivery process, additional bending moment, and influence on the pile quality and even damage to the pile body.

[0007] Therefore, in order to solve the above problems, it is necessary to provide a double chuck large-depth H-shaped pile delivery equipment and a pile delivery method, which can meet the requirements of large-depth pile delivery and solve the problem of unstable clamping of the H-shaped pile.

[0061] The pile feeding process of the pile feeding device of this embodiment is as follows: when the pile is fed using the device, first, the position of the stabilizing mechanism is determined, the base 1 contacts the ground soil body with a compressive strength of at least 25 MPa to prevent equipment subsidence problems affecting the pile forming quality during the pile feeding process, then the position of the inclined brace 4 is quickly adjusted by the control room 3 to control the main lifting rod 11 and the secondary lifting rod 5, thereby adjusting the position of the main column 7, the adjustable angle range of the inclined brace 4 is 45-60°, and after adjustment, the height, angle and position of the clamping mechanism can be adjusted by the winch 12, the guide wheel line 9 and the pulley block 6, and the center of the clamping mechanism is aligned with the center of the web portion of the H-shaped pile, then the relative position of the clamping mechanism and the H-shaped pile is adjusted, and the outer sides of the left clamping plate 18 and the right clamping plate 24 are respectively closely attached to the upper and lower flange portions of the H-shaped pile, and the error of the two sides is within 50 mm, so that the clamping mechanisms are symmetrically arranged, on the one hand, the friction between the clamping mechanism and the H-shaped pile can be increased, and on the other hand, the H-shaped pile can be guaranteed to be uniformly stressed during the pile feeding process, and additional bending moment affecting the pile forming quality is prevented.

[0062] Then the winch 12, guide wire 9 and pulley block 6 are controlled to lower the clamping mechanism, at this time the rated speed of the guide wire 9 on the winch 12 drum is 6-12 m / min, when the left and right clamping plates 24 of the clamping mechanism can be completely projected on the web portion of the H-shaped pile, the clamping mechanism is controlled to clamp the H-shaped pile, at the same time the winch 12, guide wire 9 and pulley block 6 are controlled to continuously lower the counterweight assembly 8, pile depth measuring arm 10 and clamping mechanism, the H-shaped pile is driven into the soil by the weight of the counterweight assembly 8, during the pile driving process, the center of the counterweight assembly 8, pile depth measuring arm 10, clamping mechanism and H-shaped pile should be approximately on the same straight line, at the same time the worker observes the scale line 26 on the pile depth measuring arm 10, when the designed pile depth is reached, the lowering is stopped, the clamping mechanism is controlled to be released, and the clamping mechanism is slowly lifted to the initial position by the winch 12, guide wire 9 and pulley block 6, at this time the rated speed of the guide wire 9 on the winch 12 drum is 6-8 m / min, thereby the overall operation is completed.
