Description

Technical Field

[0001] This utility model relates to the field of pipe pile construction technology, and in particular to a PHC pipe pile strip centering positioner. Background Technology

[0002] Traditional PHC pipe pile installation methods involve using steel wire ropes or slings to hoist the PHC pipe piles into the borehole. When the PHC pipe pile is inserted, the verticality is adjusted and controlled by a pile driver or a theodolite to ensure it meets the required verticality. However, once the PHC pipe pile is fully inserted, its verticality cannot be adjusted, easily leading to tilting or toppling within the borehole. This results in uneven distribution of the protective layer thickness, severely affecting the pile's load-bearing capacity. Especially when the PHC pipe pile is used as a vertically load-bearing component, insufficient verticality can easily compromise the quality of the load-bearing structure.

[0003] Currently, centering positioners are generally used to keep the pipe piles centered and vertical during drilling. However, most positioners have a complex structure and are difficult to install, which affects construction efficiency. Summary of the Invention

[0004] This utility model aims to address the shortcomings of existing technologies by providing a PHC pipe pile strip centering positioner.

[0005] To achieve the above objectives, this utility model adopts the following technical solution:

[0006] A PHC pipe pile strip centering positioner includes:

[0007] A series of protrusions are pre-installed on the outer wall of the pipe pile from top to bottom, and the protrusions are in the shape of a ring.

[0008] Positioning steel pipes are evenly distributed around the circumference of each pair of bosses and inserted between their opposite faces.

[0009] The binding straps are used to fix several positioning steel pipes in series, and the two ends of the binding straps are tied together.

[0010] Specifically, the boss is a concrete boss.

[0011] Specifically, the protrusion is a circular steel plate pre-embedded on the outer wall of the pipe pile.

[0012] Specifically, the binding strap is made of nylon rope, and there are through holes in the middle of both sides of the positioning steel pipe. The nylon rope passes through the through holes and is fixed to the positioning steel pipe by knotting. The two ends of the nylon rope are also knotted for fixation.

[0013] Specifically, the binding strap is made of nylon. The outer wall of the positioning steel pipe has a groove in the middle. The nylon strap is bonded and fixed to the groove. One end of the nylon strap has a buckle, and both ends of the nylon strap are fixed by the buckle.

[0014] Specifically, the bottom of the positioning steel pipe is tilted away from the side of the pipe pile.

[0015] The beneficial effects of this utility model are as follows: By setting up a boss, positioning steel pipe, and binding strap, this utility model can effectively keep the PHC pipe pile in a centered and vertical state in the borehole, ensuring that the verticality of the PHC pipe pile in the borehole meets the requirements, ensuring that the PHC pipe pile is subjected to vertical force, and guaranteeing the quality of the pile body; at the same time, the locator has a simple structure, and the installation process only requires one person to operate, saving labor costs. It is easy to operate, convenient to construct, saves time and effort, and improves the hoisting efficiency of PHC pipe piles. Attached Figure Description

[0023] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0025] Example 1

[0026] like Figures 1-4 , Figure 6 As shown, a PHC pipe pile strip centering positioner includes:

[0027] A number of protrusions 2 are pre-installed on the outer wall of the pipe pile 1 from top to bottom. The protrusions 2 are circular and are made of concrete. The protrusions 2 provide installation space for the locator and can limit the positioning steel pipe 3. The positioning steel pipe 3 is easy to install.

[0028] Positioning steel pipes 3 are evenly distributed around the circumference of each pair of bosses 2 and inserted between their opposite faces. The bottom of the positioning steel pipes 3 is inclined on the side away from the pipe pile 1, and the corners at the intersection of the inclined surfaces are rounded to facilitate lowering into the borehole.

[0029] The binding straps are used to fix several positioning steel pipes 3 in series, and the two ends of the binding straps are tied and fixed. The binding straps are nylon ropes 4. There are through holes 5 in the middle of both sides of the positioning steel pipes 3. The nylon ropes 4 pass through the through holes 5 and are fixed by knotting. The two ends of the nylon ropes 4 are tied and fixed.

[0030] When this utility model is in operation, a suitable positioning steel pipe 3 is selected according to the borehole diameter. A through hole 5 is processed in the positioning steel pipe 3. Then, a nylon rope 4 is passed through the positioning steel pipe 3, and knots are tied on both sides of the positioning steel pipe 3 to fix the positioning steel pipe 3. Then, the series-connected positioning steel pipes 3 are inserted between a pair of bosses 2. After wrapping around once, the two ends of the nylon rope 4 are tightly tied and fixed. At this time, the centering positioner is installed. When the pipe pile 1 is lowered into the borehole, the positioning steel pipe 3 is in close contact with the inner wall of the borehole to ensure that the pipe pile 1 is centered and lowered vertically.

[0031] Example 2

[0032] like Figure 1 , Figure 5 , Figure 6 As shown, a PHC pipe pile strip centering positioner includes:

[0033] Boss 2, several pairs of bosses 2 are pre-installed on the outer wall of the pipe pile 1 from top to bottom. The bosses 2 are circular and are circular steel plates pre-embedded on the outer wall of the pipe pile 1. The setting of bosses 2 provides installation space for the positioner, which can limit the positioning steel pipe 3. The positioning steel pipe 3 is easy to install.

[0034] Positioning steel pipes 3 are evenly distributed around the circumference of each pair of bosses 2 and inserted between their opposite faces. The bottom of the positioning steel pipes 3 is inclined on the side away from the pipe pile 1, and the corners at the intersection of the inclined surfaces are rounded to facilitate lowering into the borehole.

[0035] A binding strap is used to fix several positioning steel pipes 3 in series, and the two ends of the binding strap are also fixed. The binding strap is a nylon strap 6. The outer wall of the positioning steel pipe 3 has a groove 7 in the middle. The nylon strap 6 is bonded and fixed to the groove 7. One end of the nylon strap 6 has a belt buckle 8. The two ends of the nylon strap 6 are fixed by the belt buckle 8.

[0036] When this utility model is in operation, a suitable positioning steel pipe 3 is selected according to the borehole diameter, and a groove 7 is processed on the positioning steel pipe 3. Then, a nylon strap 6 is bonded to the groove 7 of several positioning steel pipes 3. Then, the series-connected positioning steel pipes 3 are inserted between a pair of bosses 2. After wrapping around once, one end of the nylon strap 6 is passed through the belt buckle 8 and tightly fastened and fixed. At this time, the centering positioner is installed. When the pipe pile 1 is lowered into the borehole, the positioning steel pipe 3 is in close contact with the inner wall of the borehole to ensure that the pipe pile 1 is centered and lowered vertically.

[0037] This invention effectively keeps PHC pipe piles centered and vertical in the borehole, ensuring that the verticality of the PHC pipe piles meets the requirements, guaranteeing the vertical force on the PHC pipe piles, and ensuring the quality of the pile body. At the same time, the locator has a simple structure, and the installation process only requires one person to operate, saving labor costs. It is easy to operate, convenient to construct, saves time and effort, and improves the hoisting efficiency of PHC pipe piles.
