Problems solved by technology

[0004] In order to prevent the damage to the pile foundation during the process of setting the casing, the present invention proposes an anti-breakage device for pulling out the underwater inclined pile, which adopts the construction technology for preventing the fracture of the underwater inclined pile, and is used to solve the Since most of the pile foundations are in the water, it is difficult to judge their inclination, and the technical problems of the pile foundation below the water surface are difficult to locate

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0019] like Figure 1 to Figure 3 As shown, the anti-broken pile device for pulling out an underwater inclined pile of the present invention includes a seamless spiral steel pipe 1 (divided into two sections), a groove steel plate 2 (several pieces), and a cylindrical roller 3. The seamless spiral steel pipe 1 is provided with several groove steel plates 2 on the inner wall of the entrance end of th...

Abstract

The invention relates to an underwater inclined pile pulling-out anti-breaking pile device. The device is provided with a seamless spiral steel pipe, the seamless spiral steel pipe is provided with aplurality of groove steel plates on the inner wall of the inlet end of a pile body to be pulled, and the plurality of groove steel plates are uniformly arranged along the inner wall of the seamless spiral steel pipe; and cylindrical rollers are arranged on the position, located on the upper portions of the groove steel plates, of the inner wall of the seamless spiral steel pipe, and grooves are correspondingly formed in the front ends of the plurality of groove steel plates. The device is not only suitable for pulling out pile foundation of a water area wharf, but also is suitable for pullingout pile foundation of a land, no matter whether the pile foundation is an inclined pile or a vertical pile, the pile body can be prevented from being damaged in the pulling-out process, and the problem that an underground pile foundation obstacle is difficult to clean is effectively solved.

Description

technical field [0001] The invention relates to an underwater pile foundation removal device, in particular to an anti-broken pile device which can prevent piles from being damaged during the removal process of pile foundations in wharves in water areas. Background technique [0002] It has been 30 years since the construction of shield tunnels in Shanghai across the Yangtze River, across the Huangpu River, and across various waters. From the initial construction of the No. A large number of tunnels cross the Yangtze River, Huangpu River, Suzhou Creek and other waters. During the traversing process, the shield section will inevitably pass through the completed ferry or vehicle wharf, and the pile foundation of the pier will become an obstacle for the shield tunneling construction. In most cases, at the initial stage of the construction of the wharf, the shield tunneling will not be considered in the later stage, and there is no reserved space at the axis of the tunnel, so t...
