Problems solved by technology

At present, there are mainly three driving methods for steel pipe piles: piling ship, integrated square barge, and elevating platform ship. However, piling with piling barge has the disadvantages of high cost and single performance; although integrated square barge piling saves ship machine It is expensive to use, but it is greatly affected by waves, and the piling accuracy is not easy to guarantee; the lifting platform ship piling improves the adaptability to wave conditions and the piling accuracy, but the cost is relatively high
At the same time, the installation of steel pipe piles has the characteristics of frequent parking, which puts forward high requirements for piling ships or elevating platform ships under severe wave conditions

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] The construction method of the pile top movable platform steel pipe pile designed by the present invention comprises the following steps:

[0032] Step 1: Set up multiple rows of steel pipe piles 1 (such as Image 6 shown);

[0033] Step 2: Select continuous three rows of steel pipe piles 1 according to construction needs, install an elevation adjustment device 2 on the top of the pile, and operate the elevation adjustment device 2 to clamp the top of the steel pipe pile 1 (such as Image 6 shown);

[0034] Step 3: Build the platform running track 3 on the top of the last two rows of steel pipe piles 1 located in the moving direction of the platform, so that the axis direction of the running track 3 is the same as the moving direction of the platform (such as figure 1 , Image 6 shown);

[0035] Step 4: Set up the clamping...

Abstract

The invention discloses a pile block movable platform steel pipe pile driving construction method. The method comprises the steps that an elevation adjustment device is utilized for erecting a movable platform, a pile clamping platform is erected at the rear portion of the platform, a pile driving guide frame is arranged at the front portion of the platform, and the platform is pulled through a core-crossing jack and a precision rolling screw-thread steel rod to move. Steel pipe pile driving and pile clamping construction are converted from water to land, the influence caused by wave conditions is small, the influence of waves is greatly lowered, and the method is particularly suitable for the region with the severe wave condition. The platform is simple in structure and low in manufacturing cost, all components can be recycled, the platform can be conveniently installed and moved forwards, steel pipe pile driving and pile clamping construction are integrated, the working efficiency is high, the working procedures are reduced, large-equipment input is lowered, and the cost is remarkably lowered. Platform standing, steel pipe pile driving and pile clamping construction are easy to control, and precision is high.

Description

technical field [0001] The invention relates to the technical field of pile foundation construction equipment, in particular to a construction method for steel pipe piles on platforms with movable pile tops. Background technique [0002] Due to its hollow structure, the high-pile wharf has a good effect on weakening waves, and its adaptability to super-deep dredging has become a widely used wharf form, and the construction of steel pipe piles is particularly critical in the entire construction process. At present, there are mainly three driving methods for steel pipe piles: piling ship, integrated square barge, and elevating platform ship. However, piling with piling barge has the disadvantages of high cost and single performance; although integrated square barge piling saves ship machine It is expensive to use, but it is greatly affected by waves, and the piling accuracy is not easy to guarantee; the lifting platform piling improves the adaptability to wave conditions and t...
