Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated pipe pile construction, in particular to a structure suitable for preventing slag from falling and filling the core and sealing the bottom of prefabricated pipe piles. Background Art

[0002] During the process of sinking and after the pile sinking is completed, the top of the prefabricated pipe pile is generally lower than the ground. Especially in power transmission and transformation projects, in order to avoid the inconvenience of long-term expansion and sinking, the long-term pipe piles are often sunk in place at one time in this period. In order to prevent safety accidents, the top of the prefabricated pipe pile needs to be covered with soil in time and then dug up during expansion. This causes external mud, earthwork, and debris such as broken stones to easily fall into the core of the pipe pile. Before filling the core at the top of the pile, the debris in the pile head must be cleaned up first, otherwise the core filling depth required by the design cannot be guaranteed, and the holes on the top of the pile are prone to cause personnel falling accidents, which poses a major safety hazard and is not conducive to the passage of mechanical equipment, and mechanized operating conditions are difficult to guarantee. The traditional solution is to use a hook spoon or a shovel to bend the front section to clean it, which is labor-intensive, inefficient, time-consuming, and ineffective; or use templates or steel plates for capping or setting safety guardrails, which are easy to slide and run, and safety guardrails are overkill.

[0003] For this purpose, we design a structure suitable for preventing slag from falling off and filling the core and sealing the bottom of prefabricated pipe piles. Utility Model Content

The sealing plate 21 is fixedly mounted on the top of the short round tube 23. The reinforcing aid 22 is fixedly mounted at the top center of the sealing plate 21. The reinforcing aid 22 is cross-shaped. An external thread 23-1 is arranged on the outer wall of the short round tube 23. The interior of the short round tube 23 is filled with concrete. Please refer to Figure 1 The inner wall of the prefabricated pipe pile 1 is provided with an internal thread 1-1 that cooperates with the external thread 23-1. The plugging piece 2 is connected to the prefabricated pipe pile 1 through a thread. The plugging piece 2 can play a role in plugging the prefabricated pipe pile 1, thereby preventing external mud, earthwork, and debris such as broken stones from falling in and preventing personnel from falling. When the plugging piece 2 is moved to the bottom of the core-filled concrete, it can play a role in core-filling plugging. Through the cooperation of the thread, the plugging piece 2 can be rotated to make the plugging piece 2 move vertically. , thereby adjusting its position in the prefabricated pipe pile 1. The internal thread 1-1 on the inner side of the prefabricated pipe pile 1 can enhance the friction and bonding between the core-filled concrete and the inner wall of the prefabricated pipe pile after core filling, thereby reducing the core filling depth. The length of the internal thread 1-1 satisfies the rotation and fixation of the core filling assembly. Generally, the core filling depth is more than 3m, so the length of the internal thread 1-1 is preferably about 5m. The sealing plate 21 is made of steel plate, the stiffener 22 is made of steel stiffener, and the short round tube 23 is made of steel pipe;

[0023] See also Figure 4-Figure 6 The long handle 3 is composed of a plurality of sleeve sections 31, and the overall length of the long handle 3 can be adjusted by adjusting the extended length of each sleeve section 31. The side of each sleeve section 31 is provided with a plurality of equally spaced circular holes 31-2 that penetrate the sleeve 31. Two adjacent sleeves 31 are locked by bolts 32 passing through the circular holes 31-2. Nuts are tightened on the bolts 32. A slot 31-1 is provided at the bottom end of the lowest sleeve 31. The slot 31-1 is cross-shaped and can cooperate with the stiffening aid 22. The sleeve 31 is made of steel pipe, and the slot 31-1 is connected to the stiffening aid 22. The plugging member 2 can be driven to rotate by rotating the long handle 3. The bolt 32 is made of steel bolt.

[0024] The working principle and use process of the utility model: when the utility model is used for the structure of preventing slag from falling and filling the core to seal the bottom of the prefabricated pipe pile, before sinking the pile, place the plugging piece 2 on the prefabricated pipe pile 1, align the external thread 23-1 on the short round tube 23 with the internal thread 1-1 on the prefabricated pipe pile 1, and then screw the plugging piece 2 into the top of the pipe pile until the top of the reinforcement 22 is about 100mm away from the top of the prefabricated pipe pile 1. After sinking and delivering the pile, backfill the earth and use the plugging piece 2 to seal the top of the prefabricated pipe pile 1. During and after pile sinking, prevent external mud, earth, gravel and other debris from falling in, and prevent people from falling accidents. When filling the core, dig up the top of the pile to fill the soil. After cleaning the soil and rocks on the top of the sealing member 2, connect the slot 31-1 on the long handle 3 with the reinforcement 22 on the sealing member 2, and then rotate the long handle 3 to move the sealing member 2 to the bottom of the designed pile core, which can play the role of core filling and plugging. After tying the core filling steel cage, put it into the pile top hole, pour the core filling concrete, and complete the core filling work.
