Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a pile pad for static pressure concrete pipe piles. Background Art
[0002] Static-pressed concrete pipe piles, also known as static-pressed prestressed concrete pipe piles, are a novel foundation construction technology based on prestressed steel and concrete forming techniques. These piles utilize a specific pressure to pack concrete into steel pipes and prestress the pipes with prestressed steel bars to achieve geometric stability and increase bearing capacity. During construction, the prefabricated pipe piles are driven into the soil using the deadweight of the static pile driver and the counterweights on the pile frame. This pile-sinking process is known as the static-pressing method.
[0003] Static pressure concrete pipe piles are generally suitable for industrial and civil building foundations on soft soils such as artificial plain fill, silt soil, clay soil, and silt soil. They should not pass through crushed stone layers, pebble layers, frozen soil, expansive soil, etc., nor should they be used as bearing layers with crushed stone, pebble, or weathered rock.
[0004] In the prior art, the main function of the pile pad is to reduce the hammer stress of the pile (although static pressure piles do not use hammering, the "hammer stress" here can be understood as the pressure stress generated during the pile pressing process), so that the pressure distribution is uniform and the impact time (more accurately, the time of the pile pressing process in static pressure piles) is extended, thereby facilitating the penetration of the pile. However, the pile pad may be deformed or damaged due to pressure during use. Utility Model Content
[0005] The purpose of the utility model is to provide a pile pad for static pressure concrete pipe piles, which has a simple structure, is easy to install and disassemble, and is simple to operate. It can facilitate timely replacement of the pile pad after it is damaged, thereby improving construction efficiency.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A pile pad for statically pressed concrete pipe piles comprises a mounting seat and a pressure-bearing pile pad arranged on the mounting seat; the mounting seat is connected to a pile driver, and a plurality of connecting rods are arranged on the mounting seat; a plurality of connecting holes adapted to the connecting rods are arranged in the pressure-bearing pile pad, and a plurality of locking holes are arranged on one side of the pressure-bearing pile pad, each locking hole is respectively connected to a corresponding connecting hole, and a locking pin is inserted into the locking hole, and a socket adapted to the locking pin is provided at the bottom of the connecting rod.
[0008] Furthermore, each of the connecting rods includes an outer tube and an inner tube movably connected in the outer tube, and the socket is provided at the end of the inner tube.
[0009] Furthermore, a connecting rod anti-slip ring is provided inside the outer cylinder, and an anti-slip step is provided at one end of the outer cylinder.
[0010] Furthermore, the connecting holes are L-shaped after being connected with the locking holes, and are evenly distributed in the pressure pile pad.
[0011] Furthermore, the locking pin passes through the locking hole and is connected to the socket at the bottom of the connecting rod.
[0012] Furthermore, the pile pad has a thickness between 50 mm and 100 mm.
[0013] Compared with existing technologies, the advantages of the present invention are: the pile mat of the present invention acts as a buffer layer during the pile driving process, protecting the pile body from direct impact and wear, and also protecting the pile driver from excessive reaction forces. Furthermore, the present invention can be fixed by inserting a locking pin and released by removing the locking pin, allowing for quick replacement of the pile mat, thereby reducing downtime and improving construction efficiency.

[0018] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.
[0019] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.
[0020] In the description of the present invention, it should be noted that if the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the utility model product is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0021] In addition, the terms "first", "second", "third", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.
[0022] Furthermore, the use of terms such as "horizontal," "vertical," and "overhanging" does not necessarily imply that the component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted.

[0023] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0024] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.
[0025] like Figure 1-Figure 2 As shown, a pile pad for statically pressed concrete pipe piles comprises a mounting base 1 and a pressure-bearing pile pad 2 arranged on the mounting base 1; the mounting base 1 is connected to a pile driver, and a plurality of connecting rods are provided on the mounting base 1; a plurality of connecting holes 5 adapted to the connecting rods are provided in the pressure-bearing pile pad 2, and a plurality of locking holes 7 are provided on one side of the pressure-bearing pile pad 2, each locking hole 7 is respectively connected to a corresponding connecting hole 5, and a locking pin is inserted into the locking hole 7, and a socket 6 adapted to the locking pin is provided at the bottom of the connecting rod.
[0026] In the prior art, the pile pad of a static pile refers to the buffer material placed between the pile top and the pile driver during the construction of the static pile. The materials of the pile pad of a static pile are diverse, and commonly used ones include polyethylene sheets, rubber sheets, wood, etc. These materials each have their own characteristics. For example, polyethylene sheets have high compressive strength and toughness, rubber sheets have excellent elasticity and impact resistance, and wood has strong compressive strength and good toughness. The pile pad should be placed between the pile top and the pile driver to ensure that the pile pad is in full cross-section contact with the pile top to avoid damage to the pile body due to excessive local force. However, as a consumable part, the pile pad requires a long downtime period to replace during long-term use. The pile pad of the present invention serves as a buffer layer during the pile driving process, which can protect the pile body from direct impact and wear, and can also protect the pile driver from the influence of excessive reaction force. At the same time, the present invention can be fixed by inserting a locking pin and released by removing the locking pin, so that the pile pad can be quickly replaced, thereby reducing downtime and improving construction efficiency.
[0027] Each connecting rod comprises an outer tube 3 and an inner tube 4 movably connected within the outer tube 3. The receptacle 6 is located at the end of the inner tube 4. A connecting rod anti-drop ring 9 is installed within the outer tube 3, and an anti-drop step 8 is provided at one end of the outer tube 3. The connecting rod is designed as a two-stage structure. Before the pile mat is deployed, the inner tube 4 extends into the bottom of the connecting hole 5 due to its own weight. During deployment and gradual deformation due to compression, the inner tube 4 gradually retracts into the outer tube 3 according to the degree of deformation, preventing damage to the connecting rod during compression. The anti-drop ring and anti-drop step 8 ensure that the inner tube 4 does not fall or otherwise fall in the direction of movement.
[0028] The connecting hole 5 is connected to the locking hole 7 to form an L shape and is evenly distributed in the pressure pile pad 2. The locking pin passes through the locking hole 7 and is connected to the socket at the bottom of the connecting rod.
[0029] The thickness of the pile pad is between 50mm and 100mm.
[0030] In actual use, the utility model sets the pile pad as an easily detachable part, which is respectively set as a pressure pile pad 2 and a mounting base, and the mounting base is connected to the static pressure pile foundation, and adopts a strong metal material. As the pressure pile pad 2 with a certain elasticity, it is necessary to adopt a material with a thickness between 50mm-100mm and good buffering and compression resistance, such as honeycomb paper, cardboard, etc. These materials can effectively absorb and disperse the pressure generated during the pile pressing process, protecting the pile body and pile driver from damage. The pile pad can reduce the pressure stress generated during the pile pressing process, making the pressure distribution more uniform, thereby reducing the risk of damage to the pile body and pile driver. Due to the material problem of the pile pad, after a period of use, its thickness will be significantly reduced, and its rigidity will gradually increase, slowly losing effectiveness. At this time, it is necessary to replace the pile pad, but in the utility model, it is only necessary to remove the locking pin, then the locking will lose effectiveness, and replace the pressure pile pad 2. The overall structure is simple and easy to implement.
[0031] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
