[0002] With the continuous development of global trade, wharves bear the heavy responsibility of load transfer, cargo loading and unloading, and ship berthing. Hydraulic structures are a crucial part of wharf construction; their stability and reliability directly affect the safe, stable, and long-term operation of the entire wharf.
[0003] Crushed stone piles are an important criterion for assessing the load-bearing capacity of wharves. They are mainly used to fix and support various marine structures, such as wharves, seawalls, and breakwaters. Underwater construction of crushed stone piles requires immersed tubes. However, when current immersed tubes are inserted into the seabed, silt can enter the interior of the tubes. This silt can lead to insufficient load-bearing capacity of the crushed stone piles, reduced quality, and even consequences such as pile breakage or necking. If additional treatment measures are used to remove the silt, it will increase the construction difficulty, construction time, and construction costs. Utility Model Content

Detailed Implementation
[0034] In existing immersed tube technology, when the tube is inserted into the seabed, silt will enter the tube. The silt inside the tube will lead to insufficient bearing capacity of the crushed stone pile, reduced quality, and even cause pile breakage or necking. If additional treatment measures are used to remove the silt, it will increase the construction difficulty, construction time and construction cost.
[0035] In view of this, the present application provides an umbrella-type three-door pile tip, which has three pile tip doors hinged to the bottom of the cylinder. The inner side of the pile tip door is hinged to a door connecting rod, and the other end of the door connecting rod is hinged to a movable slider. The movable slider is slidably sleeved on a limiting pin, which is sleeved on an upper positioning sleeve fixedly installed with the cylinder. A top rod is sleeved on the limiting pin and below the movable slider. The bottom of the top rod passes through the lower positioning sleeve fixedly connected to the cylinder and connects to the pile tip. When the pile tip is inserted into the seabed, the three pile tip doors close, and their lower ends fit onto the outside of the lower positioning sleeve, isolating the inside and outside of the pile tip and effectively preventing the pipe from sinking. When the immersed tube is inserted into the seabed, sediment enters the interior. When the pile foundation material is injected into the immersed tube, the pile foundation material pushes the pile tip panel outward, expanding the foundation support surface. At the same time, the movable slider drives the top rod to move downward, allowing the pile tip to penetrate further into the seabed, improving stability. This solves the technical problem in the existing technology where sediment enters the immersed tube when it is inserted into the seabed. Sediment entering the immersed tube can lead to insufficient bearing capacity of the crushed stone pile, reduced quality, and even consequences such as pile breakage and necking. If additional treatment measures are used to remove the sediment, it will increase the technical difficulty, construction time, and construction cost.

That is, the upper positioning sleeve 2 and the lower positioning sleeve 3 are fixedly connected to the cylinder 1 through the door panel support plates 10.
[0045] The limiting pin 4 is sleeved inside the upper positioning sleeve 2. The movable slider 5 and the top rod 6 are both movably sleeved on the limiting pin 4, and the movable slider 5 is supported on the top rod 6. The end of the top rod 6 away from the movable slider 5 passes through the lower positioning sleeve 3. The top ends of the three pile tip gate plates 8 are all hinged to the lower end of the cylinder 1. Each of them has a door connecting rod 9 on its inner side. One end of the door connecting rod 9 is hinged to the pile tip gate plate 8, and the other end is hinged to the movable slider 5. When the three pile tip gate plates 8 are closed, the three pile tip gate plates 8 form a frustum structure that is larger at the top and smaller at the bottom. Its upper end is attached to the bottom end of the cylinder 1, and its lower end is sleeved on the outside of the lower positioning sleeve 3. The pile tip 7 is connected to the end of the top rod 6 away from the movable slider 5.
[0046] Specifically, when the three pile tip door panels 8 are closed, the inner sides of two adjacent pile tip door panels 8 abut against the bottom end of one door panel support plate 10. To ensure that the pile tip door panels 8 fit better against the door panel support plate 10, chamfers 11 are provided on both sides of the lower end of the door panel support plate 10 and on the inner sides of both ends of the pile tip door panels 8. The three door panel support plates 10 are spaced apart, and the interval between two adjacent door panel support plates 10 is 120°. Each pile tip door panel 8 is hinged to the cylinder 1 through two hinge components. The two hinge components are spaced apart. The hinge component includes two first door hinges 12, a second door hinge 13, and a first rotating pin 14. The two first door hinges 12 are symmetrically spaced and connected to the outer side of the bottom end of the cylinder 1. The top end of the second door hinge 13 is located between the two first door hinges 12 and is rotatably connected to the two first door hinges 12 through the first rotating pin 14. The bottom end of the door hinge 13 is fixedly connected to the outer side of the pile tip door panel 8. Each pile tip door panel 8 has a first door ear 16 on its inner side. The movable slider 5 has three second door ear 17 on its outer side. One end of the door connecting rod 9 is hinged to the first door ear 16 through a second rotating pin, and the other end is hinged to the second door ear 17 through another second rotating pin. The pile tip 7 includes a first pile tip plate 18 and two second pile tip plates 19. The two second pile tip plates 19 are symmetrically welded to the two sides of the middle of the first pile tip plate 18, and the second pile tip plates 19 are perpendicular to the first pile tip plate 18. Preferably, the top end of the middle of the first pile tip plate 18 is provided with a through groove, and the second pile tip plate 19 is provided with a connecting notch near the top end of the first pile tip plate 18. The through groove and the two connecting notches together form a connecting groove 20 that is recessed into the pile tip 7. The pile tip 7 is fixedly connected to the bottom end of the top rod 6 through the connecting groove 20.
[0047] The bottom end of the top rod 6 is inserted into the connecting groove 20 and then welded to improve the connection stability between the pile tip 7 and the top rod 6.
[0048] In some preferred embodiments, a cylinder reinforcing rib 15 is fixedly sleeved on the outer side of the cylinder 1, and the first door hinge 12 is connected to the side of the cylinder reinforcing rib 15 away from the cylinder 1. That is, the cylinder reinforcing rib 15 is located between the cylinder 1 and the first door hinge 12. By setting the cylinder reinforcing rib 15, the radial load capacity of the cylinder 1 is increased.
[0049] In some preferred embodiments, three door panel limiting blocks 21 are evenly spaced on the outer side of the cylinder 1. The top end of the door panel limiting block 21 is connected to the cylinder 1, and its bottom end is located on the outer side of the pile tip door panel 8. Each door panel limiting block 21 corresponds to one pile tip door panel 8. By setting three door panel limiting blocks 21, the maximum outward opening position of the pile tip door panel 8 is limited, preventing the pile tip door panel 8 from opening excessively and affecting the stability of the pile foundation.
[0050] Specifically, the top of the door panel limiting block 21 is connected to the cylindrical body reinforcing rib 15, that is, the door panel limiting block 21 is connected to the cylindrical body 1 through the cylindrical body reinforcing rib 15.
[0051] In summary, the umbrella-type three-door pile tip provided in this application embodiment has three pile tip doors hinged to the bottom of the cylinder. The inner side of the pile tip door is hinged to a door connecting rod, and the other end of the door connecting rod is hinged to a movable slider. The movable slider is slidably sleeved on a limiting pin, which is sleeved on an upper positioning sleeve fixedly installed with the cylinder. A top rod is sleeved on the limiting pin and below the movable slider. The bottom of the top rod passes through a lower positioning sleeve fixedly connected to the cylinder and connects to the pile tip. When the pile tip is inserted into the seabed, the three pile tip doors close, and their lower ends fit onto the outside of the lower positioning sleeve, isolating the inside and outside of the pile tip and effectively preventing sinking. When the pipe is inserted into the seabed, sediment enters the pipe. When the pile foundation material is injected into the pipe, the pile foundation material pushes the pile tip panel outward, expanding the foundation support surface. At the same time, the movable slider drives the top rod to move downward, allowing the pile tip to penetrate further into the seabed, improving stability. This solves the technical problem in the existing technology where sediment enters the pipe when it is inserted into the seabed. Sediment entering the pipe can lead to insufficient bearing capacity of the crushed stone pile, reduced quality, and even cause pile breakage or necking. If additional treatment measures are used to remove the sediment, it will increase the construction difficulty, construction time, and construction cost.
