Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anti-freezing and tamping, in particular to a PHC pipe pile anti-freezing and tamping device. Background Art
[0002] Frost heave prevention tamping is a method used in cold climates to reduce soil frost heave through compaction. This technique is primarily used to increase the density of foundations or fill materials, thereby enhancing their resistance to frost heave. Tamping involves repeatedly dropping a heavy object onto the foundation or fill materials to increase their density. In the construction industry, tamping is a crucial step in foundation construction and plays a crucial role in preventing soil frost heave.
[0003] The mechanism of action of anti-frost heave compaction: 1. Through compaction, the gaps between soil particles are compressed, the soil becomes more compact, and the volume expansion space generated by water during the freezing process is reduced, thereby increasing the soil density; 2. Compacting can change the arrangement of soil particles, making them more stable and less susceptible to freeze-thaw cycles, thereby improving the soil structure; 3. Dense soil has better thermal insulation properties and can slow down the rate of temperature drop inside the soil, thereby reducing the risk of soil freezing and enhancing the soil's frost resistance.
[0004] At present, when carrying out the anti-freeze expansion tamping of PHC pipe piles, workers generally use mechanical tamping machines. Mechanical tamping machines are heavy and inconvenient to carry, install and operate, especially when multiple PHC pipe piles need to be operated. It is even more troublesome, requires a lot of manpower and material resources, and has high operating costs. Utility Model Content

[0023] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.
[0024] Please refer to the attached Figure 1-3 The following is a description of a specific embodiment of the present invention: A PHC pile anti-freezing and compacting device includes a protective sleeve 1 that is movably mounted on the outside of a pile 8. A locking mechanism is provided at the top of the protective sleeve 1 for locking the pile 8. The locking mechanism secures the protective sleeve 1 to the outside of the pile 8, thereby securing the device to the outside of the pile 8.
[0025] Specifically, the locking mechanism includes a shrinkage kit and a locking hoop 3. The shrinkage kit is arranged at the top of the protective sleeve 1 and can be movably sleeved on the outside of the pipe pile 8. The locking hoop 3 is sleeved on the outside of the shrinkage kit. The locking hoop 3 can tighten the shrinkage kit and the pipe pile 8. By tightening the locking hoop 3, the shrinkage kit can be tightened to the pipe pile 8, thereby fixing the protective sleeve 1 on the outside of the pipe pile 8.
[0026] Specifically, the retraction kit includes two arc-shaped elastic clamps 2, both of which are fixed to the top of the protective sleeve 1 and symmetrically arranged on both sides of the pipe pile 8. The two elastic clamps 2 can clamp the pipe pile 8 and have a certain degree of adjustment capability to accommodate pipe piles 8 of different diameters.
[0027] Inside the protective sleeve 1, lifting rods 4 are positioned on either side of the pipe pile 8, parallel to each other. Slideways 101 corresponding to the lifting rods 4 are defined on either side of the protective sleeve 1. A handle 5 slides within the slideways 101. The inner end of the handle 5 extends into the interior of the protective sleeve 1 and connects to the top of the lifting rods 4. The bottom end of the lifting rod 4 extends below the protective sleeve 1 and connects to the annular hammer 6, which fits over the outside of the pipe pile 8. The handle 5 can move up and down along the slideways 101, driving the lifting rods 4 and, in turn, the annular hammer 6.
[0028] The working principle of the present invention is as follows: when in use, the construction worker first loosens the locking clamp 3 of the locking mechanism, then installs the protective sleeve 1 together with the annular hammer 6 on the pipe pile 8. After determining the position, the locking clamp 3 is installed to fix the device on the pipe pile 8. After the fixation is completed, the construction worker pulls the annular hammer up and down through the handle 5 to compact the anti-frost heave layer.
[0029] In one embodiment, the bottom surface of the annular hammer body 6 is provided with a plurality of conical hammer heads 7. The design of the hammer heads 7 can increase the mass of the annular hammer body 6, thereby increasing the tamping quality.
[0030] In one embodiment, the ring-shaped hammer body 6 is detachably connected to the lifting rod 4 by bolts. Through the above detachable design, the staff can replace the ring-shaped hammer body 6 of different qualities according to the actual working conditions, thereby improving the flexibility of the device.
[0031] In one embodiment, the annular hammer body 6 is detachably connected to a counterweight body via bolts, and the outer end of the handle 5 is detachably connected to a counterweight handle via bolts. This detachable design can indirectly increase or decrease the mass of the annular pituitary body 6, thereby improving the flexibility of the device.
