Description

Technical Field

[0001] The utility model relates to the technical field of concrete pipe piles, in particular to a concrete pipe pile which is convenient for lifting and positioning. Background Art

[0002] Prestressed concrete pipe piles have the characteristics of strong bearing capacity, good resistance to impact, strong penetration, short construction period, convenient construction, easy pile layout, and low comprehensive cost. They can be widely used in industrial and civil buildings, bridges, highways, railways, ports, water conservancy and other projects. The general processing technology of prestressed concrete pipe piles is: first, the ends of multiple steel bars at both ends of the steel cage are buckled on the two end plates, and then hoisted into the steel mold and poured with concrete, and finally formed by centrifugation. The existing concrete pipe piles are placed on the ground after processing. At this time, it is very inconvenient to bypass the concrete pipe piles when installing the lifting rope on the pipe piles. In addition, when lifting with the lifting rope, the lifting rope and the concrete pipe pile are prone to slippage, which leads to the problem of inconvenience in lifting; at the same time, when stacking, it is easy for the end faces of the concrete pipe piles to be uneven.

[0003] Patent application number CN202221965847.X discloses a concrete pipe pile that is convenient for lifting and positioning. The existing concrete pipe piles are processed and placed on the ground. At this time, it is very inconvenient to install a lifting rope on the pipe pile by bypassing the concrete pipe pile, and when lifting with the lifting rope, the lifting rope and the concrete pipe pile are prone to slippage, which leads to the problem of inconvenience in lifting; at the same time, the end faces of the concrete pipe piles are prone to unevenness when stacked. The concrete pipe pile body includes a pipe pile body, and a plurality of annular grooves arranged along the length direction are arranged on the circumferential side of the pipe pile body, and an annular iron sleeve is arranged on the circumferential side of the annular iron sleeve. A plurality of lifting rings distributed in a circular array and for the lifting rope to pass through during lifting are arranged, and the lifting rings do not protrude from the range of the annular grooves. The utility model has the following advantages and effects: by arranging multiple annular grooves on the pipe pile body, and arranging annular iron sleeves and multiple lifting rings in the annular grooves, it is convenient to pass the lifting rope through the multiple lifting rings to achieve bundling and lifting during lifting, which has the effect of facilitating lifting; and because the positions of the lifting rings in multiple places are fixed on the pipe pile body, the connection position of the lifting rope and the pipe pile body is fixed, which is convenient for aligning the ends of the pipe pile during the process of lifting by a crane; at the same time, because the lifting ring does not protrude from the annular groove, the existence of the lifting ring will not affect the placement and use of the pipe pile body. However, the above technical solution is easy to bend during the lifting of the pipe pile by arranging multiple annular grooves on the pipe pile body, and arranging annular iron sleeves and multiple lifting rings in the annular grooves. At the same time, the annular iron sleeve is easy to rust in the soil for a long time, causing soil pollution.

[0004] Therefore, we made improvements on this and proposed a concrete pipe pile that is easy to lift and position. Utility Model Content

[0020] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0021] Example: Figure 1-3As shown, the utility model is a concrete pipe pile convenient for lifting and positioning, comprising a pipe pile body 1, a plurality of trapezoidal blocks 2 are sleeved on the peripheral side of the pipe pile body 1, a plurality of rope threading holes 3 are opened on the top of the plurality of trapezoidal blocks 2, and the rope threading holes 3 pass through the bottom of the trapezoidal blocks 2, a bayonet assembly is installed at the joint between the trapezoidal blocks 2 and the pipe pile body 1, and the bayonet assembly includes a plurality of chambers 6 opened on the inner wall of the pipe pile body 1, a mounting hole 8 is installed between two adjacent chambers 6, and a limit plate 9 is installed inside the plurality of chambers 6 A spring 7 is connected to one side of the limit plate 9, and the other end of the spring 7 is connected to the end of the chamber 6 away from the limit plate 9. A limit block 10 is installed on the other side of the limit plate 9. Through the coordinated use of the chamber 6, the mounting hole 8, the limit plate 9, the spring 7, the limit block 10 and the T-block 5, when the T-block 5 on the trapezoidal block 2 is pushed to move into the mounting hole 8, the limit block 10 drives the limit plate 9 to move into the chamber 6, so that the T-block 5 is engaged with the mounting hole 8, and the pile body 1 and the trapezoidal block 2 are quickly installed.

[0022] Among them, a plurality of T-blocks 5 are installed on the inner wall of the trapezoidal block 2, and the T-block 5 passes between two adjacent limit blocks 10 and is snap-fitted into the mounting hole 8. Since the cross-section of the limit block 10 is an irregular shape, when the T-block 5 is snap-fitted into the inside of the mounting hole 8 through the limit block 10, the bayonet assembly has self-locking properties.

[0023] Among them, raised blocks 4 are installed at both ends of one half of the trapezoidal block 2, and grooves are opened at both ends of the other half of the trapezoidal block 2. The raised blocks 4 are engaged with the grooves. The engagement of the raised blocks 4 with the grooves facilitates the installation of the trapezoidal block 2 on the pipe pile body 1. When the pipe pile body 1 is driven into the soil, the trapezoidal block 2 plays a role in resisting pull-out.

[0024] The rope holes 3 inside the trapezoidal block 2 are symmetrically distributed, and the plurality of rope holes 3 on the trapezoidal block 2 can better cooperate with the downward pressing of the pipe pile body 1 to prevent the pipe pile body 1 from bending during the lifting process.

[0025] The material of the trapezoidal block 2 is stainless steel, which has good corrosion resistance and can prevent the trapezoidal block 2 from rusting and causing soil pollution.

[0026] Working principle: When using this kind of concrete pipe pile which is convenient for lifting and positioning, the trapezoidal block 2 is clamped and sleeved on the pipe pile body 1. The trapezoidal block 2 plays a role of resisting pull-out. During the process of sleeve installation, the T-block 5 on the trapezoidal block 2 will be pushed to move into the installation hole 8, and the limit block 10 will drive the limit plate 9 to move into the chamber 6, so that the T-block 5 is clamped into the installation hole 8. The pipe pile body 1 and the trapezoidal block 2 can be quickly installed and have a self-locking effect. When the concrete pipe pile needs to be lifted, the lifting rope is passed through the rope threading hole for lifting, and the rope threading holes 3 are symmetrically distributed, which improves the stability after being connected with the lifting rope. Through the above design, the several rope threading holes 3 on the trapezoidal block 2 can better cooperate with the downward pressure of the pipe pile body 1 to prevent the pipe pile body 1 from bending during the lifting process, and at the same time, it can also avoid the pollution of soil caused by rust of iron products.
