Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-uplift pile technology, specifically to a synergistic anti-buoyancy structure based on double-row piles and anti-uplift piles. Background Technology
[0002] Tension-resistant piles, also known as anti-buoyancy piles, are piles installed in building construction to counteract the buoyancy force exerted on the structure by soil water when the underground structure is below the surrounding water level. Tension-resistant piles primarily rely on the friction between the pile and the soil layer to resist axial tensile forces, ensuring the stability and safety of the structure.
[0003] When installing tension piles, the bottom of the pile is usually inserted into the soil layer below the river channel, and it is fixed by the friction between the pile and the soil layer below the river channel. However, in actual use, tension piles usually generate upward buoyancy, causing them to float upwards and become loose, which affects normal use.
[0004] Therefore, we propose a synergistic anti-buoyancy structure based on double-row piles and anti-uplift piles to solve the problems mentioned above. Utility Model Content

The tops of the support piles and tension piles are fitted with the same mounting frame, which is used to fix the support piles and tension piles. A base plate is provided on the top of the mounting frame, and a frame is fixed to the edge of the base plate.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0017] A synergistic anti-buoyancy structure based on double-row piles and anti-tension piles includes several support piles 1, which are arranged in two rows to form a double-row pile structure. Typically, the double-row piles are built on the ground. It should be noted that the piles in the front row are called the front row piles, and vice versa. Several tension piles 2 are set in front of the double-row piles (that is, several support piles 1); under normal circumstances, tension piles 2 are used to build the interior of the river channel; In detail: the support pile 1 includes a first mounting base 101 buried in the ground, and a support beam 102 is vertically fixed to the top of the first mounting base 101, and the top of the support beam 102 is set through the ground. In detail: The anti-tension pile 2 includes a second mounting base 201 installed below the river channel, and the second mounting base 201 is buried in the silt below the river channel. The top of the second mounting base 201 is vertically fixed with an anti-tension beam 202. Under normal circumstances, the height of the anti-tension beam 202 is lower than that of the support beam 102.
[0018] The top of several support beams 102 and several tension beams 202 are equipped with the same mounting frame 3. The mounting frame 3 serves to fix the several support beams 102 and several tension beams 202. The top of the mounting frame 3 is equipped with a base plate 4. In detail: The mounting frame 3 includes several fixed supports 301 and several mounting supports 302. The fixed supports 301 are fixed to the top of the support beam 102. The mounting supports 302 are installed on the top of the anti-tension beam 202. Crossbeams 303 are fixed between adjacent fixed supports 301, between adjacent mounting supports 302, and between adjacent fixed supports 301 and mounting supports 302. The arrangement of the crossbeams 303 serves to fix the fixed supports 301 and the mounting supports 302. In more detail: the mounting support 302 is a hollow structure; the top of the anti-tension beam 202 is fixed with an insert shaft 203 so that the bottom end of the mounting support 302 can be inserted into the insert shaft 203 to prevent the mounting support 302 from tilting during use; the top of the insert shaft 203 is fixed with several reinforcing ribs 204 extending into the mounting support 302. After concrete is poured into the interior of the mounting support 302, the concrete can solidify on the inner wall of the mounting support 302 and the several reinforcing ribs 204, thereby reinforcing the mounting support 302 and preventing the mounting support 302 from moving during use, thus having strong stability.
[0019] It should be noted that the base plate 4 consists of several precast slabs 401, with each precast slab 401 having its two ends placed on the crossbeams 303 to provide support.
[0020] Furthermore, a surrounding plate 5 is fixed to the top of the base plate 4. The surrounding plate 5 serves to shield and prevent concrete from leaking from the edge of the base plate 4. It should be noted that the surrounding plate 5 and the base plate 4 form a pouring trough, and a concrete layer 6 is poured inside the pouring trough. The front part of the concrete layer 6 can apply downward pressure to several tension piles 2 to prevent several tension piles 2 from becoming suspended.
[0021] It should be noted that the concrete layer 6 has an internal reinforcing layer 7. The reinforcing layer 7 serves to strengthen the concrete layer 6 and prevent it from cracking over time.
[0022] In detail: The reinforcement layer 7 includes several steel bars 701, which are placed horizontally and vertically. The connection between every two steel bars 701 can be tied with wire or welded to achieve the reinforcement effect and prevent the steel bars 701 from loosening during use.
