In addition, the terms "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0024] The present embodiment is mainly divided into land and water parts, and the following procedures can be followed during implementation: land construction: foundation setting-out - undisturbed soil compaction and sandbag slope protection - graded broken stone backfill - concrete hardening; water construction: measurement setting-out - pile machine positioning - steel pipe pile hammering into pile - steel pipe forming support structure - walkway plate construction in launching area - water floating cylinder / barrel - steel pipe fixed connection into steel structure frame - arrangement of walkway plate of water floating platform.

[0025] As shown in Figure 1 , 2 The floating body assembly platform provided by the present embodiment for the floating photovoltaic power station is composed of a turnover area 1 and an assembly area 2 on land, which are mainly used for temporary stacking and assembly of floating bodies / units.

[0026] The ground of the turnover area 1 is composed of a graded gravel backfill layer 5 and a concrete surface layer 6. The ground of the assembly area 2 is composed of a sand bag backfill layer 13, a graded gravel backfill layer 5 and a concrete surface layer 6. The in-situ soil compaction and sand bag slope protection can utilize the on-site excavated earthwork, mechanically load the sand bags and manually spread, economically and effectively preventing the water flow and wave scouring of the embankment and preventing the landslide accidents on the water side of the embankment. For the in-situ soil compaction, the cohesive soil can be compacted by a sheep foot roller and the non-cohesive soil can be compacted by a cylinder roller, with a compaction degree not less than 0.9. The gravel with a particle size of 40-200 mm is preferably used for the layered backfill, the large stones are first backfilled and compacted, the small stones are used for the compaction of the interstitial gaps and the surface layer, the spreading thickness is 20-40 cm, the cohesion between the in-situ soils and the foundation bearing capacity are enhanced. The concrete surface layer 6 is poured with C20 plain concrete, with a thickness of 10-20 cm, on the one hand, the working surface is ensured to be flat, preventing the floating body assembly from being cut or scratched, on the other hand, the foundation bearing capacity is appropriately improved, the concrete surface layer 6 of the assembly area 2 gradually reduces in height towards the water side, forming a slope surface.

[0027] To ensure the construction of the project throughout the year, the assembly area 2 and the turnover area 1 are both provided with a semi-enclosed workshop. The semi-enclosed workshop includes a plurality of workshop support members and a roof 12, the workshop support members are combined into a frame structure and fixed on the ground, and the roof 12 is fixedly laid on the top of the frame structure. Generally, the workshop support members are light square steel 11, and the roof 12 is made of color steel plate.

[0028] The waterborne part of the embodiment is composed of a launching area 3 and a waterborne floating platform 4, the launching area 3 is connected with the assembly area 2 and mainly completes the launching of the floating body array and the connection on the water surface, and then is moved to the permanent square anchor area by a tugboat.

[0029] As shown in Figure 2 , the launching area 3 is provided with two rows of steel pipe piles 7 in front and behind, the rear row of steel pipe piles 7 is arranged along the shore, and the front row of steel pipe piles 7 is kept a distance from the rear row of steel pipe piles 7. The lower parts of the two rows of steel pipe piles 7 are deeply embedded in the underwater bearing layer, the upper parts are connected with each other through a support structure 8, and the top of the support structure 8 is paved with the walkway plate 9. The waterborne floating platform 4 is connected with the launching area 3 through a cable or other similar flexible connecting member, so as to moor the waterborne floating platform 4 to the shore.

[0030] As shown in Figure 3As shown, the support structure 8 comprises several vertically adjustable supports 8.1 and several horizontal steel pipes 8.2. In each of the two rows of steel pipe piles 7, the top of each steel pipe pile 7 is fixed with three vertically adjustable supports 8.1, and all the vertically adjustable supports 8.1 are gradually raised in height from front to back, i.e. the height of the front vertically adjustable supports 8.1 is lower than that of the back vertically adjustable supports 8.1. The upper ends of the vertically adjustable supports 8.1 on the two adjacent rows of steel pipe piles 7 are connected one by one by the horizontal steel pipes 8.2, and the walkway plate 9 is laid on the top of the horizontal steel pipes 8.2. Since the vertically adjustable supports 8.1 on the two rows of steel pipe piles 7 are of different heights, the horizontal steel pipes 8.2 are arranged obliquely, and the walkway plate 9 is substantially parallel to the horizontal steel pipes 8.2, with the higher side being flush or close to the bank and the lower side being flush, close to or slightly lower than the water surface.

[0031] The vertically adjustable support 8.1 comprises several vertical steel pipes 8.11, active fasteners 8.12 (such as cross / straight fasteners) and reinforcing members. The lowermost vertical steel pipe 8.11 is connected to the steel pipe pile 7 by an angle steel 14. The vertical steel pipes 8.11 and the horizontal steel pipes 8.2 are fixed together by the active fasteners 8.12. Radial perforations 8.13 are formed in the vertical steel pipes 8.11, and reinforcing members are inserted into the perforations 8.13 on the upper side and / or lower side of the active fasteners 8.12. The reinforcing members can be selected from bolts or pins. The reinforcing members can further reinforce the stability of the steel pipe connections.

[0032] The steel pipe pile 7 has a pile diameter of not less than DN200, and the part above the water is not less than 0.5m in height. The vertical steel pipe 8.11 and the horizontal steel pipe 8.2 have a diameter of not less than 48mm, and the angle steel 14 can be a 50 angle steel 14, which serves to connect and reinforce the support.

[0033] The floating platform 4 above the water is provided with a steel structure frame 10, the bottom of which is fixed with a group of oil drums or pontoons as floating bodies. The steel structure frame 10 can effectively fix the floating bodies, and the walkway plate laid on the steel structure frame 10 provides an effective working platform for the floating bodies to enter the water.

[0034] The floating platform 4 above the water requires that the horizontal and horizontal arrangement spacing of the floating bodies / oil drums is not greater than 3.0m, and the total weight of the components entering the water meets the buoyancy requirement. The number of floating bodies needs to be reasonably arranged according to the bearing capacity of the floating platform 4 above the water to avoid the phenomenon of insufficient buoyancy causing instability of the platform.

[0035] In terms of shortening the construction period, the embodiment utilizes the existing site or directly backfills the excavated earth to form the land part of the assembly platform, and divides different construction areas according to the construction sequence, which can effectively shorten the construction period and improve the resource utilization rate.

[0036] In terms of site system planning, the embodiment divides the site according to different functions, and proposes four functional divisions of the turnover area 1, the assembly area 2, the launching area 3, and the water floating platform 4, which effectively arranges the site according to the photovoltaic module construction process, so that the installation of the floating body and the module is more efficient and convenient.

[0037] The water floating platform 4 is a working platform formed by connecting the floating cylinders / barrels in series, which mainly relies on the buoyancy provided by the floating cylinders / barrels to balance the gravity generated by the assembly of the floating body / module and the workers on the platform. The launching area 3 and the water floating platform 4 are connected in a flexible manner by a cable mooring to prevent the launching area 3 or the supporting structure 8 from being rigidly deformed due to the fluctuation of the water surface. The launching area 3 provides a transportation channel for the single assembled floating body and module, and the water floating platform 4 mainly undertakes the work of assembling the floating bodies and installing the cables between the modules.

[0038] The embodiment solves the problem of high water level fluctuation in the following ways. First, the water floating platform 4 is made of floating cylinders / barrels with good buoyancy. When the water level fluctuates greatly, the water floating platform 4 with strong buoyancy will change with the water level, and most importantly, the platform remains as a whole, providing a stable and reliable working surface for the assembly of the floating body / module. Second, the launching area 3 is supported by a stable pile foundation, and the vertical support 8.1 of the supporting structure 8 is connected by vertical steel pipes 8.11 through active fasteners 8.12. If the water level rises, in order to effectively connect the water floating platform 4 and the assembly area 2 on the shore, the inclination angle of the horizontal steel pipe 8.2 can be changed by increasing the number of vertical steel pipes 8.11 and reducing the overlap length between the vertical steel pipes 8.11, and finally the inclination angle of the walkway plate 9 of the launching area 3 is changed, so that the lower side of the walkway plate 9 is always flush with, close to, or slightly lower than the water surface. Conversely, if the water level drops, the inclination angle of the horizontal steel pipe 8.2 can be changed by removing the vertical steel pipes 8.11 or increasing the overlap length between the steel pipes, and finally the inclination angle of the walkway plate 9 of the launching area 3 is changed, so that the lower side of the walkway plate 9 is always flush with, close to, or slightly lower than the water surface. The higher side of the walkway plate 9 is always flush with or close to the shore.

[0039] In the aspect of high amplitude water level problem, the embodiment proposes a combination scheme of steel pipe pile 7 and support structure 8, the different working elevations of the platform of lower water area 3 are adjusted by controlling the vertical height of support structure 8, the high water level amplitude is adapted by using the float / oil drum, and sufficient buoyancy is provided, and the two effectively solve the problem of high water level amplitude. The assembled photovoltaic floating body and assembly can be moved to the permanent anchoring square matrix by means of the water tugboat.

[0040] The above only describes the preferred embodiments of the present application, and various modifications and changes can be made to the present application for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
