[0002] Concrete pipe piles are mainly made of concrete and steel materials. Concrete pipe piles are mainly made of concrete as raw material, and are manufactured by centrifugal pile making or prefabricated piles. Steel pipe piles are based on steel and are manufactured by welding or threaded connection. Concrete pipe piles have the characteristics of high single pile bearing capacity, low unit bearing capacity cost, fast construction speed, and reliable pile quality. Generally, they are suitable for soft soil, clay soil, silt soil, sandy soil and fully weathered rock mass, and are widely used in several construction fields;

[0003] However, when using concrete pipe piles to lay electric wires in mountainous areas, because the natural conditions at the construction site are poor, the portion of the concrete pipe piles inserted into the soil must have strong tensile and anti-tilting characteristics. However, the existing concrete pipe piles do not have a supporting and pulling structure at the bottom, which makes it easy for the portion of the concrete pipe piles inserted into the soil to tilt and collapse due to soil changes, external tension or natural disasters, resulting in no time for emergency repairs and causing serious accidents that endanger people's personal safety.

[0004] Therefore, it is urgent to improve the concrete pipe pile to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a concrete pipe pile, which can increase the tensile and anti-tilting properties of the bottom of the pipe pile body through a supporting and pulling structure inserted into the soil, so as to improve the overall stability of the pipe pile, so that if the part of the concrete pipe pile inserted into the soil encounters soil changes, external tension or natural disasters, it will not cause the concrete pipe pile to tilt or collapse to a large extent, thereby providing time for emergency repairs and at the same time will not cause serious accidents that endanger people's personal safety.

[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include: a pipe pile body, a first connecting base is arranged on the lower bottom surface of the pipe pile body, a supporting and pulling structure is arranged on the lower bottom surface of the first connecting base, the supporting and pulling structure includes a second connecting base, a hollow square tube arranged on the lower surface of the second connecting base, storage slots opened on the surface around the hollow square tube, a movable baffle hinged inside the storage slot, and an embedded end arranged under the hollow square tube, and the movable baffle is movably connected to the inner wall of the hollow square tube through a metal chain.

[0007] Preferably, the two sides of the lower end of the movable baffle are hinged to the two sides of the lower end of the receiving slot, and the movable baffle is provided with an outward-turned mud-entry tip block at the end away from the hinge, and a first connecting block is provided on the inner side of the mud-entry tip block, and a plurality of barbed protrusions are provided on the outer side of the movable baffle, and a movable baffle baffle strip is provided inside the receiving slot near the inner wall of the hollow square tube.

[0008] Preferably, a second connecting block is provided at a position corresponding to the receiving slot at the top end of the inner wall of the hollow square tube, and the first connecting block and the second connecting block are connected by a metal chain.

[0009] Preferably, a plurality of first threaded holes are formed on the first connection base, and a second threaded hole having a position corresponding to that of the first threaded holes and a size identical to that of the first threaded holes is formed through the upper surface of the second connection base.

[0010] Preferably, the first connecting base and the second connecting base are fixed by bolts, and the second threaded hole and the first threaded hole are screwed and connected by the bolt threads.

[0011] Preferably, a bolt rubber plug for hiding the bolt is provided in the second threaded hole.

[0012] Preferably, a plurality of exhaust holes are formed on the outer side of the pipe pile body away from one end of the supporting pulling structure, and metal supporting ring blocks are arranged in each of the exhaust holes.

[0013] Preferably, the top end of the embedded end head is configured to be conical, and the surface of the metal chain is sprayed with an anti-rust paint layer.

[0014] The utility model has at least the following beneficial effects:

[0015] 1. The utility model can increase the tensile and anti-tilting properties of the bottom of the pipe pile body by inserting a supporting and pulling structure into the soil. When subjected to a slight tilt and shaking, the barbed protrusions on the movable baffle plate will tightly grip the soil to reduce the tilt. When subjected to a larger tilt and shaking, the movable baffle plate will slowly open up with the shaking of the pipe pile body. As the shaking of the pipe pile body becomes more intense, the movable baffle plate will open further through the outward-turned mud-entering sharp blocks to penetrate the surrounding soil, so that the bottom of the pipe pile body has a larger contact surface with the soil, thereby improving the overall stability of the pipe pile. As a result, if the part of the concrete pipe pile inserted into the soil encounters soil changes, external tension or natural disasters, it will not cause the concrete pipe pile to tilt or collapse to a large extent, so that there is time for emergency repairs, and at the same time, it will not cause serious accidents that endanger people's personal safety.

When the pipe pile body 1 shakes, the movable baffle 6 can slowly expand with the shaking amplitude of the pipe pile body 1, and insert into the surrounding soil to increase the contact area between the bottom of the pipe pile body 1 and the soil, so that the pipe pile will not tilt or collapse to a large extent. The embedded end 7 is convenient for driving the pipe pile body 1 into the mud faster, and the metal chain 102 is convenient for pulling and fixing the movable baffle 6, so that the movable baffle 6 can only be opened to a certain angle.

[0024] The two sides of the lower end of the movable baffle plate 6 are hinged to the two sides of the lower end of the storage slot 5. The movable baffle plate 6 is provided with an outward-turned mud entry tip block 8 at the end away from the hinge. A first connecting block 9 is provided on the inner side of the mud entry tip block 8. A plurality of barbed protrusions 10 are provided on the outer side of the movable baffle plate 6. A movable baffle plate baffle bar 103 is provided near the inner wall of the hollow square tube 4 inside the storage slot 5. The mud entry tip block 8 facilitates the movable baffle plate 6 to be better inserted into the mud when it is stretched out. The first connecting block 9 facilitates the connection of the metal chain 102 to the mud entry tip block 8 on the movable baffle plate 6. The barbed protrusions 10 are intended to increase the resistance of the movable baffle plate 6 to the mud.

[0025] A second connecting block 11 is provided at a position corresponding to the receiving slot hole 5 at the top end of the inner wall of the hollow square tube 4 . The first connecting block 9 and the second connecting block 11 are connected by a metal chain 102 . The second connecting block 11 facilitates connecting the metal chain 102 to the inner wall of the hollow square tube 4 .

[0026] A plurality of first threaded holes 12 are provided on the first connecting base 101, and second threaded holes 13 corresponding to the positions of the first threaded holes 12 and having the same size as the first threaded holes 12 are provided through the upper surface of the second connecting base 3. The first connecting base 101 and the second connecting base 3 are fixed by bolts 14, and the second threaded holes 13 and the first threaded holes 12 are threadedly connected by the bolts 14. The first threaded holes 12, the second threaded holes 13 and the bolts 14 can fix the supporting pulling structure 2 on the first connecting base 101.

[0027] A bolt rubber plug 17 for hiding the bolt 14 is arranged in the second threaded hole 13. The bolt rubber plug 17 can prevent the bolt 14 from rusting when the bottom of the concrete pipe pile is driven into the mud.

[0028] A plurality of exhaust holes 15 are provided on the outer side of the pile body 1 away from the end of the supporting pulling structure 2. Metal support ring blocks 16 are provided in the exhaust holes 15. The exhaust holes 15 facilitate the smooth discharge of gas in the pile when the pile is sunk. The metal support ring blocks 16 can support the exhaust holes 15 and increase the compressive strength of the exhaust holes 15.

[0029] The top of the embedded end 7 is set to be conical, so as to just enter the mud. The surface of the metal chain 102 is sprayed with an anti-rust paint layer to prevent the metal chain 102 from rusting.

[0030] like Figure 1-Figure 4 As shown, the principle of the concrete pipe pile provided in this embodiment is as follows: when the device is used, the pipe pile body 1 should be placed horizontally first, and then the supporting pulling structure 2 should be fixed to the first connecting base 101 at the lower end of the pipe pile body 1 by bolts 14, and at the same time, the bolt rubber plug 17 should be inserted into the exposed opening of the second threaded hole 13, and then the hoisting vehicle will adjust the pipe pile body 1 together with the supporting pulling structure 2 to be vertical, and then drive it into the required soil through the precast pile driver, and when the concrete pipe pile is driven into the soil, the movable blocking plate 6 will be tightly fitted in the receiving slot 5 due to the extrusion of the soil;

[0031] When the concrete pipe pile is tilted and shaken by external influence, if it is a slight shake, the movable baffle plate 6 is a barbed protrusion 10 on the surface which will increase the contact area with the soil, thereby increasing the resistance to prevent shaking. If it shakes violently, the amplitude of the shaking will increase and the movable baffle plate 6 will slowly open from the receiving slot hole 5. At the same time, the mud-entering tip block 8 will slowly insert into the surrounding soil as the concrete pipe pile shakes, and the excess soil will also be poured into the hollow square tube 4. At this time, one end of the metal chain 102 will pull the movable baffle plate 6, and the other end will pull the supporting and pulling structure 2 fixedly connected to the first connecting base 101 under the pipe pile body 1, so that the bottom of the concrete pipe pile will shake accordingly to better insert into the soil and fit more closely to the soil, thereby preventing the concrete pipe pile from tilting or collapsing to a greater extent, and gaining more repair time for maintenance personnel, while reducing the occurrence of accidents and protecting people's personal safety as much as possible.
