Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a prestressed high-strength concrete pipe pile. Background Art

[0002] Prestressed high-strength concrete pipe piles, namely PHC piles, also known as prestressed pipe piles, are hollow cylindrical slender concrete precast components made by prestressing technology and centrifugal forming. GB13476-2009 stipulates that the concrete strength grade of PHC should not be lower than C80, that is, the compressive strength should be greater than 80MPa. In actual applications, if it is to adapt to complex terrain, it must be above C90.

[0003] The current structural design of prestressed high-strength concrete pipe piles often ignores the interaction with the surrounding environment, which leads to corrosion in moist and highly corrosive soils, thereby reducing the overall strength of the pipe piles. At the same time, when the pipe piles are subjected to external forces, stress concentration is prone to occur due to uneven force distribution, which increases the risk of pipe pile breakage, causing premature damage to the pipe piles, affecting their service life, increasing maintenance costs, and reducing engineering safety performance. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model proposes a prestressed high-strength concrete pipe pile, which significantly improves the performance stability, durability and construction efficiency of the prestressed high-strength concrete pipe pile, thereby enhancing its safety and reliability.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a prestressed high-strength concrete pipe pile, comprising a pipe pile body and high-strength bolts, wherein a pre-set steel bar skeleton is fixedly arranged in the pipe pile body, an aluminum alloy casing is fixedly installed on the circumference of the pipe pile body, an inverted triangle positioning ring is fixedly installed on the circumference of the aluminum alloy casing, a threaded ring is fixedly installed on one side of the aluminum alloy casing, a threaded groove is provided on the other side of the aluminum alloy casing, and the high-strength bolts penetrate the aluminum alloy casing and are threadedly connected to the pre-set steel bar skeleton.

[0006] Preferably, the pre-placed steel bar skeleton is formed by welding a plurality of annular reinforcing hoops and a plurality of column-type reinforcing bars, and is evenly distributed inside the pipe pile body.

[0007] Preferably, a threaded sleeve is fixedly installed on the periphery of the prefabricated steel bar skeleton and extends to the periphery of the aluminum alloy sleeve.

[0008] Preferably, the threaded collar on one side of the aluminum alloy casing is threadedly connected to the thread groove of another aluminum alloy casing, and the threaded collar of the other aluminum alloy casing is threadedly connected to a percussion drill bit.

[0009] Preferably, the aluminum alloy sleeve and the circumference of the inverted triangle positioning ring are coated with polyurethane coating.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] This type of prestressed high-strength concrete pipe pile has an aluminum alloy casing fixedly arranged on the side of the pipe pile body. The aluminum alloy casing has good corrosion resistance and can effectively prevent the pipe pile from being eroded by environmental factors such as soil and moisture, thereby extending the service life of the pipe pile. The inverted triangle positioning ring is arranged on the side of the aluminum alloy casing, so that the force on the pipe pile body is more uniform when it is subjected to pressure or tension, making the pipe pile more stable when subjected to external force and less likely to be deformed or damaged.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-Figure 4A prestressed high-strength concrete pipe pile comprises a pipe pile body 1 and a high-strength bolt 4. A preset steel bar skeleton 7 is fixedly arranged inside the pipe pile body 1, providing it with a strong structural support force. An aluminum alloy casing 2 is fixedly installed on the periphery of the pipe pile body 1. The aluminum alloy material itself has good corrosion resistance and can resist the erosion of humidity, chemicals and the like in the environment. An inverted triangle positioning ring 3 is fixedly installed on the periphery of the aluminum alloy casing 2. The fixed installation of the inverted triangle positioning ring 3 provides additional support and fixation for the aluminum alloy casing 2, significantly enhancing the stability of the entire structure. A threaded ring 5 is fixedly installed on one side of the aluminum alloy casing 2, and a threaded groove is opened on the other side of the aluminum alloy casing 2. The high-strength bolt 4 penetrates the aluminum alloy casing 2 and is threadedly connected to the preset steel bar skeleton 7.

[0019] When in use, the pipe pile body 1 is placed in the position and direction required by the design to ensure the verticality and stability of the pipe pile. The high-strength bolts 4 penetrate the aluminum alloy casing 2 and are threadedly connected with the pre-set steel frame 7, so that the aluminum alloy casing 2 is fixedly installed on the peripheral side of the pipe pile body 1. The aluminum alloy material has excellent corrosion resistance and can resist erosion by humidity, chemicals and the like in the environment, thereby extending the service life of the pipe pile. The pre-set steel frame 7 provides a strong structural support for the pipe pile body 1, significantly enhancing the strength and stability of the pipe pile body 1. The inverted triangle positioning ring 3 fixedly installed on the peripheral side of the aluminum alloy casing 2 makes the contact area between the pipe pile body 1 and the soil relatively large, so that the pipe pile can be accurately positioned at a predetermined position, reducing the displacement of the pipe pile caused by soil movement or external force, and can adapt to soils in different environments, so that the performance stability, durability and construction efficiency of the pipe pile body 1 are significantly improved, thereby enhancing its safety and reliability.

[0020] like Figure 4 As shown, the pre-set steel bar skeleton 7 is composed of a plurality of annular reinforcing hoops and a plurality of column-type reinforcing ribs welded together, and are evenly distributed inside the pipe pile body 1. During the above-mentioned use, the annular reinforcing hoops and the column-type reinforcing ribs are welded together to form a stable pre-set steel bar skeleton 7, which enhances the overall structural strength of the pipe pile, effectively resists external pressure and impact force, and ensures that the pipe pile body 1 is not easily deformed or damaged during use.

[0021] like Figure 4 It is shown that a threaded sleeve 8 is fixedly installed on the periphery of the pre-installed steel bar skeleton 7 and extends to the periphery of the aluminum alloy casing 2. During the above-mentioned use, the fixed installation of the threaded sleeve 8 ensures a firm connection between the pre-installed steel bar skeleton 7 and the aluminum alloy casing 2. Through the extension of the threaded sleeve 8, the connection area between the pre-installed steel bar skeleton 7 and the aluminum alloy casing 2 is increased, thereby improving the strength of the overall structure.

[0022] like Figure 1 or Figure 2It is shown that the threaded ring 5 on one side of the aluminum alloy casing 2 is threadedly connected to the thread groove of another aluminum alloy casing 2, and the threaded ring 5 of the other aluminum alloy casing 2 is threadedly connected with the impact drill bit 6. In the above-mentioned use process, the threaded ring 5 is threadedly connected to the thread groove and welded to the aluminum alloy casing 2 to achieve a firm connection, so that the entire pipe pile body 1 can maintain a high structural strength and stability when subjected to external force, reducing the risk of structural failure caused by loose connection.

[0023] like Figure 1 or Figure 2 It is shown that the aluminum alloy sleeve 2 and the inverted triangle positioning ring 3 are coated with polyurethane coating. During the above use process, the polyurethane coating has excellent anti-corrosion performance and can resist the erosion of the external environment, such as humidity, acid and alkali substances, etc. Applying polyurethane coating on the aluminum alloy sleeve 2 and the inverted triangle positioning ring 3 can effectively prevent them from being corroded, thereby extending the service life of the pile body 1.
