Description

Technical Field

[0001] This utility model relates to the field of new energy engineering pile foundation technology, and more specifically, to a rigid waterproof structure at the end of a precast concrete pipe pile foundation for photovoltaic support. Background Technology

[0002] Currently, the main structural forms of precast pipe pile foundations for photovoltaic supports are as follows:

[0003] The ring-shaped end plate is open. In this method, a ring-shaped steel plate is pre-embedded at the end of the precast concrete pipe pile foundation of the photovoltaic support, and the hollow core of the precast pipe pile is open to the outside. Since the foundation of the photovoltaic support is generally raised to a certain height above the ground, when this type of precast pile with a top structure is applied to the precast concrete pipe pile foundation of the photovoltaic support in new energy projects, the opening at the top of the pile will be exposed upwards, and water or snow will enter from the top in rainy or snowy weather.

[0004] Pre-embedded closed end plate type. This method involves pre-embedding a circular steel plate at the end of the precast pile to seal the opening, which to some extent solves the problem of rain and snow entering the core of the precast pile from the end. However, this method leaves gaps at the connection between the end plate and the pile body. When the groundwater level is high, groundwater can seep into the gaps, causing water accumulation in the pile core.

[0005] In some hot-summer and cold-winter areas north of the Yangtze River, freezing conditions occur in winter. If water accumulates in the core of the precast pipe pile foundation of the photovoltaic support, it will freeze and expand. During the process of water accumulation and freezing expansion in the pile core, additional stress will be generated on the pile body. Under the action of additional stress, cracks will appear on the surface of the pile body, affecting the durability of the precast pipe pile foundation of the photovoltaic support and hindering the safe and reliable operation of the photovoltaic power generation project within its design service life. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a rigid waterproof structure at the end of the precast concrete pipe pile foundation of photovoltaic support.

[0007] This utility model discloses a rigid waterproof structure at the end of a precast concrete pipe pile foundation for a photovoltaic support. The structure is achieved through the following technical solution: a steel end plate 4 is provided at the top of the precast pipe pile, and an annular water-stop steel strip 3 is provided on the surface of the steel end plate 4. The annular water-stop steel strip extends into the side wall of the precast pipe pile, and multiple steel end plate anchor bars 5 are axially and evenly arranged on the inner side wall of the annular water-stop steel strip.

[0008] The lower part of the annular water-stop steel strip is flared to form a water-stop bend.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] Based on the weak points of waterproofing at the ends of precast concrete pipe piles, this utility model significantly improves the waterproofing effect of precast pipe pile foundations for photovoltaic power generation projects compared to the traditional end structure of precast concrete pipe piles, thereby enhancing the reliability and durability of the engineering structure.

[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this utility model pertains. The terminology used in this specification of the utility model is for the purpose of describing particular embodiments only and is not intended to limit the utility model.

[0014] like Figure 1-2 As shown, the precast pipe pile includes a precast pipe pile sidewall 1 and a precast pipe pile hollow portion 2. A steel end plate 4 is provided at the top of the precast pipe pile, and an annular water-stop steel strip 3 is provided on the surface of the steel end plate 4. The annular water-stop steel strip extends into the sidewall 1 of the precast pipe pile, and multiple steel end plate anchor bars 5 are axially and evenly arranged on the inner sidewall of the annular water-stop steel strip. The lower part of the annular water-stop steel strip is flared to form a water-stop bend.

[0015] The annular water-stop steel strip of this utility model is designed with a water-stop bend. The connection mechanical properties of the precast pipe pile steel end plate 4, the annular water-stop steel strip 3 and the precast pipe pile side wall 1 are strengthened by the steel end plate anchor bar 5. This blocks the path of groundwater seeping into the gap between the precast pipe pile steel end plate 4 and the precast pipe pile side wall 1, which greatly improves the waterproof performance of the concrete pipe pile foundation end. Moreover, the waterproof structure of this utility model is a rigid waterproof measure with high durability and is suitable for photovoltaic support concrete pipe pile foundation under specific geological conditions.

[0016] The above description is only a preferred embodiment of the present utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
