Problems solved by technology

Although this fixing method can stably position the platform on the water surface, in actual application, it is necessary to add permanent concrete pile foundations somewhere, which has poor environmental protection effect, and it is time-consuming and laborious to pour concrete pile foundations under the water, making the construction difficult

Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not limit the present invention.

[0036] Such as figure 1 As shown, the present invention provides a kind of construction method based on assembling mobile platform to carry out pile sinking, it is characterized in that: it comprises the following steps:

[0037] a. Construct steel pipe piles 1 side by side along the laying direction of sheet piles in the sheet pile construction area, the bottom surface of steel pipe piles 1 is located below the mud surface line 14, and there are 3 steel pipe piles 1 in each row;

[0038] b. A crossbeam 2 is set on the top of each row of steel pipe piles 1, and three steel pipe piles 1 jointly support the crossbeam 2 to ensure the stability of the crossbeam 2; the top of the steel pipe pile 1 is provided with a cross-shaped pile m...

Abstract

The invention provides a pile sinking construction method based on an assembly movable platform. The method comprises the following steps that a, steel pipe piles are constructed in a plate pile construction area in the plate pile paving direction side by side; b, the tops of each row of steel pipe piles are provided with a transverse beam; c, longitudinal beams are uniformly arranged between every two transverse beams at intervals and are distributed in the plate pile paving direction; d, panels parallel to the transverse beams are arranged on the longitudinal beams; e, crawler cranes are placed on a walking plane; f, guiding frames are erected between the tops of the two transverse beams which are not provided with the panels; g, plate piles are lifted through the crawler cranes, and the plate piles are constructed after being subjected to guiding positioning through the guiding frame; and h, the panels, the longitudinal plates and the guiding frames between the two transverse beams close to the plate piles are disassembled, and the steps from f to g are repeated in the area where the plate piles are not constructed. According to the pile sinking construction method based on the assembly movable platform, the stress is clear, the method cannot be influenced by wind waves, and the precision and efficiency of pile sinking are high.

Description

technical field [0001] The invention relates to the technical field of pile sinking construction on water, in particular to a construction method for sinking piles based on an assembled mobile platform. Background technique [0002] The difficulty of sinking piles in water is to maintain the stability of the pile sinking platform and ensure the accuracy of pile sinking. The common method of sinking piles over water generally uses a piling platform as the construction point for sinking steel pipe piles. There are generally two ways to use the platform at present, one is fixed by the anchor rope, and the floating platform is connected to the fixed structure on the shore by the anchor rope to position the platform. This method has a simple structure and is very convenient to install and operate. The disadvantage is that it can only be used In waters with slow flow velocity and small wind and waves, once it is applied to a watershed with turbulent flow velocity and large wind a...
