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 1

[0039] Embodiment 1: as Figure 1-7 , is the floating walking platform of the present embodiment, the floating walking platform of the present embodiment comprises a floating platform 1 and four supporting columns 2 vertically pierced on the four corners of the floating platform 1 respectively, and the floating platform 1 is a buoyant box type structure capable of It floats stably on the water surface and has a square structure. The four support columns 2 vertically pass through the four corners of the floating platform 1, and are symmetrically fixed on the floating platform 1. The upper end surface of the floating platform 1 is equipped with a fixed frame 3, which is a cylindrical structure, and the support columns 2 pass through the fixed frame. frame 3 and floating platform 1.

[0040] Such as Figure 4~5 As shown, the lower end of the fixed frame 3 is equipped with a fixed lock 5, and the upper end is fixedly equipped with a jacking jack 4, and the lower end of the jacki...

Embodiment 2

[0058] Embodiment 2: The structures of the floating walking platform and the guiding device used in this embodiment are the same as that of the device in Embodiment 1, and the method of use is the same.

[0059] During actual construction, during the jacking process, hard soil or rock structures may appear on the seabed, and the gravity of the floating platform 1 alone cannot directly drill through the structure, and the support column 2 cannot extend into the seabed. The load capacity of 1 does not meet the design requirements, if the crawler crane 7 and other devices are transported to the floating platform 1 rashly, a safety accident may occur. In order to increase the insertion depth of the support column 2, the embodiment alternately cooperates with the lifting jack 4, the fixed lock 5 and the movable lock 6 to lift the two support columns 2 on the diagonal of the floating platform 1 (such as image 3 Shown A and C two supporting columns 2) make it stop after inserting a ...

Abstract

The invention relates to the technical field of water pile sinking construction, in particular to a construction method for carrying out pile sinking based on a floating walking platform. The construction method comprises the following steps: pulling a floating platform to a pile sinking construction position, precisely positioning the floating platform, inserting a supporting post into a seabed for fixing the floating platform to the sea by virtue of matching of a lifting jack, a fixed lock and a movable block; taking the floating platform as a pile sinking construction platform to carry out pile sinking construction; and after the construction of the section is completed, pulling the floating platform out of the supporting post by virtue of reverse jacking of the lifting jack, and pulling the floating platform to the next construction section to sink and fix for carrying out pile sinking construction until construction of all pile locations is completed. According to the construction method, the floating platform can be used for quickly inserting the platform into the seabed or pulling the platform out of the seabed by virtue of matching of the supporting post, the lifting jack, the fixed lock and the movable block, so that the operation process is simple and convenient, the operation can be completed without a great deal of manpower and material resources, and therefore, the construction method has a great popularization value.

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 a floating walking 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 an...
