Description

Technical Field

[0001] This invention relates to the field of building construction technology, and specifically to a construction method for a stable measurement platform for offshore construction. Background Technology

[0002] Currently, surveying is crucial in marine engineering construction. Existing surveying work typically involves directly constructing surveying platforms in the construction area. However, during actual construction, the platforms are easily shaken by strong winds, waves, and tides, leading to significant construction errors and affecting the accuracy of the actual construction. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects of the prior art and provide a construction method for a stable measurement platform for offshore construction. This method involves constructing a first steel pipe pile and a second steel pipe pile within the construction area. An outer steel pipe pile is installed over the first and second steel pipe piles to reduce swaying caused by waves or sea winds. A connecting pipe is installed between the first and second steel pipe piles to reinforce them, thereby ensuring the stability of the measurement platform.

[0004] A construction method for a stability measurement platform used in offshore construction, comprising the following steps, aims to achieve the above objectives:

[0005] Confirm the construction area, provide the first steel pipe pile, and drive the first steel pipe column at the center of the construction area;

[0006] A plurality of second steel pipe piles are provided and driven into the construction area, with the second steel pipe piles spaced apart along the outer perimeter of the construction area.

[0007] Provide an outer steel pipe pile, the size of which is larger than that of the first steel pipe pile and the second steel pipe pile. Drive the outer steel pipe pile in the construction area. Each of the outer steel pipe piles is respectively fitted onto the first steel pipe pile and the second steel pipe pile. The outer steel pipe pile is concentrically arranged with the first steel pipe pile and the second steel pipe pile.

[0008] A connecting pipe is provided, which is passed through the outer steel pipe pile to connect the first steel pipe pile and the second steel pipe pile;

[0009] Concrete was poured into the first and second steel pipe piles;

[0010] A measuring platform is provided and is fixedly installed on top of the first steel pipe pile and the second steel pipe pile.

[0011] Furthermore, after the first steel pipe pile and the second steel pipe pile are grouted, insulation material is filled between the first steel pipe pile and the outer steel pipe pile.

[0012] Furthermore, after the first steel pipe pile and the second steel pipe pile are grouted, insulation material is filled between the second steel pipe pile and the outer steel pipe pile.

[0013] Furthermore, after connecting the first steel pipe pile and the second steel pipe pile with the connecting pipe, a fixing pipe is provided, which is passed through the outer steel pipe pile to connect two adjacent second steel pipe piles.

[0014] Furthermore, before connecting the fixed pipe to two adjacent second steel pipe piles, a through hole is opened at the position of the outer steel pipe pile corresponding to the fixed pipe, and the fixed pipe is passed through the through hole to connect the two adjacent second steel pipe piles.

[0015] Furthermore, after the fixed tube passes through the through hole, the gap between the through hole and the fixed tube is sealed.

[0016] Furthermore, before connecting the connecting pipe to the first steel pipe pile and the second steel pipe pile, an installation hole is opened on the outer steel pipe pile at the position corresponding to the connecting pipe, and the connecting pipe is passed through the installation hole to connect the first steel pipe pile and the second steel pipe pile.

[0017] Furthermore, after the connecting pipe is inserted into the mounting hole, the gap between the mounting hole and the connecting pipe is sealed.

[0018] Furthermore, before driving the first steel pipe pile into the construction area, a first steel pipe pile of appropriate size is selected based on the geological survey report of the construction area.

[0019] Furthermore, after the measurement platform is installed, measurement control points are set on the measurement platform.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] The stability of the measurement platform is ensured by constructing first and second steel pipe piles within the construction area, with outer steel pipe piles surrounding the first and second steel pipe piles to reduce swaying caused by waves or sea winds, and by installing connecting pipes between the first and second steel pipe piles to reinforce them.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] See Figure 1 A construction method for a stable measurement platform for offshore construction includes the following steps: identifying the construction area; providing a first steel pipe pile 2 and driving the first steel pipe pile at the center of the construction area; providing a plurality of second steel pipe piles 4 and driving the second steel pipe piles 4 into the construction area, with the second steel pipe piles 4 spaced apart along the outer perimeter of the construction area; providing an outer steel pipe pile 3, the outer steel pipe pile 3 being larger in size than the first steel pipe pile 2 and the second steel pipe pile 4, driving the outer steel pipe pile 3 into the construction area, with each outer steel pipe pile 3 respectively fitted onto the first steel pipe pile 2 and the second steel pipe pile 4, and the outer steel pipe pile being concentrically arranged with the first steel pipe pile 2 and the second steel pipe pile 4; providing a connecting pipe 6 and passing the connecting pipe 6 through the outer steel pipe pile 3 to connect the first steel pipe pile 2 and the second steel pipe pile 4; filling the first steel pipe pile 2 and the second steel pipe pile 4 with concrete; and providing a measurement platform 1 and fixing the measurement platform 1 on top of the first steel pipe pile 2 and the second steel pipe pile 4.

[0027] In a preferred embodiment of this invention, a piling vessel is used to drive a first steel pipe pile 2 into the construction area, embedding the bottom of the first steel pipe pile 2 into the seabed rock mass, with the top of the first steel pipe pile 2 protruding above the sea surface. A second steel pipe pile 4 is then driven into the construction area using the piling vessel. Preferably, several second steel pipe piles 4 are arranged in an equilateral triangle, with the bottom of the second steel pipe pile 4 embedded in the seabed rock mass and the top of the second steel pipe pile 4 protruding above the sea surface. The top elevation of the first steel pipe pile 2 and the top elevation of the second steel pipe pile 4 are level. An outer steel pipe pile 3 is then provided. The outer steel pipe pile 3 is driven outside the first steel pipe pile 2 and the second steel pipe pile 4. Preferably, the radius of the outer steel pipe pile 3 is more than 20 cm larger than the radius of the first steel pipe pile 2 or the second steel pipe pile 4. The bottom of the outer steel pipe pile 3 is embedded in the seabed rock. The connecting pipe 6 is connected to the first steel pipe pile 2 and the second steel pipe pile 4. Then, shrinkage concrete is filled into the first steel pipe pile 2 and the second steel pipe pile 4 to ensure the stability of the first steel pipe pile 2 and the second steel pipe pile 4. A measuring platform 1 is set on the top of the first steel pipe pile 2 and the second steel pipe pile 4. The measuring platform 1 is fixed to the top of the first steel pipe pile 2 and the second steel pipe pile 4 by welding.

[0028] Furthermore, after the first steel pipe pile 2 and the second steel pipe pile 4 are grouted, insulation material is filled between the first steel pipe pile 2 and the outer steel pipe pile 3. Preferably, the insulation material is a flexible and deformable material. By setting the insulation material between the first steel pipe pile 2 and the outer steel pipe pile 3, the influence of the huge diurnal and tidal temperature differences at sea on the temperature contraction of the first steel pipe pile 2 is reduced, improving the accuracy of the control point. Moreover, the flexible connection between the two steel pipe piles allows the flexible insulation material to absorb the impact when the outer steel pipe pile 3 is hit by external waves or tides, thereby reducing the influence of external forces on the inner first steel pipe pile 2 and reducing measurement errors.

[0029] Furthermore, after the first steel pipe pile 2 and the second steel pipe pile 4 are grouted, insulation material is filled between the second steel pipe pile 4 and the outer steel pipe pile 3. Preferably, the insulation material is a flexible and deformable material. By setting the insulation material between the second steel pipe pile 4 and the outer steel pipe pile 3, the influence of the huge diurnal and tidal temperature differences at sea on the temperature contraction of the second steel pipe pile 4 is reduced, improving the accuracy of the control point. Moreover, the flexible connection between the two steel pipe piles allows the flexible insulation material to absorb the impact when the outer steel pipe pile 3 is hit by external waves or tides, thereby reducing the influence of external forces on the inner second steel pipe pile 4 and reducing measurement errors.

[0030] Furthermore, after connecting the first steel pipe pile 2 and the second steel pipe pile 4 with the connecting pipe 6, a fixing pipe 5 is provided, which passes through the outer steel pipe pile 3 to connect two adjacent second steel pipe piles 4. Connecting adjacent second steel pipe piles 4 through the fixing pipe 5 further improves the stability of the measuring platform 1.

[0031] Furthermore, before connecting the fixed pipe 5 to two adjacent second steel pipe piles 4, a through hole is opened at the position of the outer steel pipe pile 3 corresponding to the fixed pipe 5, and the fixed pipe 5 is passed through the through hole to connect the two adjacent second steel pipe piles 4.

[0032] Furthermore, after the fixed pipe 5 passes through the through hole, the gap between the through hole and the fixed pipe 5 is sealed. By sealing the gap between the through hole and the fixed pipe 5, seawater is prevented from entering the interior of the second steel pipe pile 4 and the outer steel pipe pile 3, which would cause corrosion of the insulation material inside the second steel pipe pile 4 and the outer steel pipe pile, resulting in a decrease in their impact resistance and insulation performance.

[0033] Furthermore, before connecting the connecting pipe 6 to the first steel pipe pile 2 and the second steel pipe pile 4, an installation hole is opened on the outer steel pipe pile 3 at the position corresponding to the connecting pipe 6, and the connecting pipe 6 is passed through the installation hole to connect the first steel pipe pile 2 and the second steel pipe pile 4.

[0034] Furthermore, after the connecting pipe 6 is inserted into the mounting hole, the gap between the mounting hole and the connecting pipe 6 is sealed. By sealing the gap between the mounting hole and the connecting pipe 6, seawater is prevented from entering the interior of the first steel pipe pile 2 and the outer steel pipe pile 3, which would cause corrosion of the insulation material inside the first steel pipe pile 2 and the outer steel pipe pile, resulting in a decrease in their impact resistance and insulation performance.

[0035] Furthermore, before driving the first steel pipe pile 2 into the construction area, a first steel pipe pile 2 of appropriate size is selected according to the geological survey report of the construction area.

[0036] Furthermore, after the measurement platform 1 is installed, measurement control points are set on the measurement platform 1. Preferably, the measurement control points can be fixed to the measurement platform 1 by pre-embedding or welding.

[0037] The following describes the usage process of the construction method of a stability measurement platform for offshore construction according to the present invention.

[0038] A piling vessel is used to drive the first steel pipe pile 2 into the construction area. The bottom of the first steel pipe pile 2 is embedded in the seabed rock, while the top of the first steel pipe pile 2 protrudes above the sea surface. The piling vessel then drives the second steel pipe pile 4 into the construction area. Preferably, several second steel pipe piles 4 are arranged in an equilateral triangle, with their bottoms embedded in the seabed rock and their tops protruding above the sea surface. The top elevation of the first steel pipe pile 2 and the top elevation of the second steel pipe pile 4 are level. An outer steel pipe pile 3 is provided and driven into the first steel pipe pile. In addition to the first steel pipe pile 2 and the second steel pipe pile 4, preferably, the radius of the outer steel pipe pile 3 is more than 20 cm larger than the radius of the first steel pipe pile 2 or the second steel pipe pile 4. The bottom of the outer steel pipe pile 3 is embedded in the seabed rock mass. The connecting pipe 6 connects the first steel pipe pile 2 and the second steel pipe pile 4. Then, shrinkage concrete is filled into the first steel pipe pile 2 and the second steel pipe pile 4 to ensure the stability of the first steel pipe pile 2 and the second steel pipe pile 4. A measuring platform 1 is set on the top of the first steel pipe pile 2 and the second steel pipe pile 4. The measuring platform 1 is fixed to the top of the first steel pipe pile 2 and the second steel pipe pile 4 by welding.

[0039] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
