Embodiment 1

[0035] figure 2 A structural schematic diagram of a vibrating device for prefabricated pipe piles according to the present invention is shown. Such as figure 2 As shown, the vibration device 3 mainly includes a vibration component 31 , a hydraulic motor 32 and a slide rail 33 . The hydraulic motor 32 is supplied with high-pressure oil through known means such as an oil pipeline, and the hydraulic motor 32 drives the vibrating member 31 to vibrate.

[0036] The vibration device 3 also includes a pair of support arms 35 .

[0037] The upper ends of the pair of arms 35 are slidably fitted with the slide rails 33 , the lower ends of the pair of arms 35 are respectively provided with support plates 352 , and the middle parts of the pair of arms 35 are hinged by connecting parts 351 . The support plate 32 is preferably connected to the lower end of the support arm 35 by known means such as welding. The connection part 351 preferably adopts known connection elements such as pin...

Embodiment 2

[0042] Figure 4 It shows a top structural schematic view of another embodiment of the vibrating device for prefabricated pipe piles according to the present invention. Figure 5 shows along the Figure 4 Sectional view of line A-A. Such as Figure 4 and Figure 5 As shown, this embodiment is different from the first embodiment except that the support arm 36 is different, and other structures of the vibrating device 3 are the same. The number of the arms 36 of the vibrating device 3 involved in Embodiment 2 can be four, the four arms 36 are 90° to each other and the middle parts of the four arms 36 are respectively provided with openings 363, and the openings 363 are respectively Linked to the ring 361, the four arms 36 can rotate around the ring 361 like this. The opening portion 363 may preferably be provided as a circular hole portion.

[0043] In addition, at least four sets of limiting components 362 are provided on the circular ring 361 , and the limiting component...

Abstract

The invention provides a vibration device for a precast tubular pile. The vibration device mainly comprises a vibration part, a hydraulic motor and a slide rail, and also comprises a pair of support arms, wherein the upper ends of the support arms are respectively matched with the slide rail in a sliding way; the lower ends of the support arms are respectively provided with a support plate; and the middles of the support arms are hinged through a connecting part. Compared with the traditional method for piling by clamping the top of the precast tubular pile through a high frequency oscillation hammer, the vibration device with the structure is arranged at the bottom of the precast tubular pipe when used for piling, the vibration generated by the vibration device is directly applied to the bottom of the precast tubular pile, the loss brought by energy transfer is reduced and the piling capacity is improved.

Description

technical field [0001] The invention relates to the field of pile foundations, and more specifically, to a vibration device for prefabricated pipe piles. The invention also relates to a construction method of the prefabricated pipe pile. Background technique [0002] Pile foundation is a traditional foundation type, and it is also a widely used foundation type. The pile foundation has good vibration resistance, low cost and is conducive to the mechanization and industrialization of structural engineering, and can transmit the load of the superstructure to the deep and stable soil layer, thereby reducing foundation settlement and uneven settlement of buildings . [0003] In recent years, with the rapid development of the field of building foundations, prefabricated piles have become more and more widely used in pile foundation construction. Prefabricated piles are pre-prepared in batches in the factory, which reduces production costs, saves a lot of steel, has high bearing...
