AI Technical Summary
When used in cold regions, the PHC pipe piles of the floating photovoltaic system crack due to the freezing and swelling of the internal mud-water mixture, affecting their durability and mechanical properties.
Multiple airbags arranged vertically are inserted into the hollow cavity of the pipe pile. The buoyancy of the airbags allows them to float vertically within the hollow cavity, providing deformation space to alleviate frost heave pressure. The stable installation and removal of the airbags are ensured by cross steel plates and connecting rings.
This effectively avoids internal stress damage to the pipe pile caused by frost heave, protects the pile body from damage, and improves the durability and mechanical properties of the pipe pile.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to photovoltaic support technical field, concretely relates to a water photovoltaic support anti -frost crack pipe pile. BACKGROUND
[0002] Prestressed high-strength concrete pipe pile (PHC pipe pile for short) is widely used in water engineering construction field such as water photovoltaic support due to its high single-pile bearing capacity, wide adaptability and low cost; however, with more and more use of PHC pipe pile in cold regions, the problem of pipe pile damage and cracking caused by internal filler frost heaving gradually appears, which seriously affects the durability and mechanical properties of the pipe pile.
[0003] Specifically, in the pipe pile construction process, the soil layers such as silt clay layer, silty clay, silty fine sand layer and loose medium sand layer are prone to segregation under the impact load of high-frequency vibration hammer, which produces excess pore water pressure at the bottom of the pile pipe, and then causes a large amount of suspended slurry mixture to accumulate in the internal cavity of the pile pipe; after the pile is in place, the bottom forms a soil plug, and the slurry in the pipe deposits, hindering the infiltration of accumulated water, which causes the slurry mixture accumulated in the pipe to be in a saturated state for a long time; finally, as the temperature continues to drop, the slurry mixture in the pile gradually freezes, increasing the frost heaving force of the internal frozen soil of the pipe pile, which in turn easily causes the pipe pile to crack and damage.
[0004] In view of the above, a water photovoltaic support anti-frost crack pipe pile is proposed. UTILITY MODEL CONTENTS

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. In the case of no conflict, the embodiments in the application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.
[0026] Please refer to Figures 1-4 The above technical solutions will be described in detail by the following embodiments.
[0027] The anti-freezing pipe pile in the embodiment is used for installing the water photovoltaic support, and is arranged at the position shown in the figure. Figure 1 The hollow cavity is arranged at the axial center of the anti-freezing pipe pile, the pipe body structure with the hollow cavity is convenient for plug-in installation, and is also the common pipe pile structure on the market at present. The application adopts the PHC pipe pile of prestressed high-strength concrete pipe pile. Then in the process of installing and inserting the pipe pile, the silt at the bottom of the pond will flow into the hollow cavity, which will cause a large amount of suspended slurry mixture to gather in the internal cavity of the pile pipe, and the silt at the bottom will block the bottom end after the plug-in installation and fixation of the pipe pile, that is, the internal cavity of the hollow cavity will be filled with slurry.
[0028] The air bags 3 arranged in the upper and lower positions are inserted into the hollow cavity. In order to obtain good buoyancy effect, the air bags 3 in the embodiment adopt the cylindrical structure, and the cross-sectional diameter of the air bags 3 is smaller than the inner diameter of the hollow cavity. Figure 1 As shown in the figure, the air bags 3 will float upward under the action of buoyancy according to the actual pipe pile construction height from the construction.
[0029] As shown in the figure, the cross-shaped steel plate 1 is detachably arranged at the bottom of the pipe pile in order to obtain the installation position. Figures 2-4 The blade 5 is arranged at the bottom end of the cross-shaped steel plate 1 in order to facilitate the plug-in installation of the pipe pile structure and reduce the obstruction.
[0030] The working principle of the water photovoltaic support anti-freezing pipe pile in the embodiment is as follows: the total length of the air bags 3 needs to be higher than the water surface or the height of the pipe pile after the water in the pipe pile freezes and expands. The total length of the air bags 3 can be adjusted according to the actual situation. In the process of freezing of the slurry, the volume of the slurry increases, but based on the flexible structure of the air bags 3, the deformation ability of the compressed air bags 3 can be obtained, which avoids the problem of directly stressed and frozen pipe pile body. The air bags 3 in the example adopt the rubber capsule, and are convenient for replacement and maintenance.

[0032] In addition, if the embodiment of the utility model has the description of "first", "second" and the like, the description of "first", "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. It is obvious for those skilled in the art that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be realized in other specific forms without departing from the spirit or essential characteristics of the utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the utility model is defined by the appended claims rather than the above description, therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the utility model.
