Description

Technical Field

[0001] The present invention relates to the technical field of concrete pipe piles, in particular to a high-strength concrete pipe pile with a built-in steel bar cage. Background Art

[0002] Concrete pipe piles are a type of prefabricated engineering piles. As the foundation material of buildings, they are driven into the ground by pile drivers under specific geological environments and act under stress in buildings and structures. There are two main uses for construction pipe piles: one is to transfer the weight of the upper building to the lower soil layer with high bearing capacity through the pipe piles, thereby improving the stability of the building; the other is to compact the soft soil layer, thereby increasing the bearing capacity of the foundation soil. The use of pipe piles can greatly reduce the cost of the foundation, and the strength is also sufficient. Therefore, they are widely used in engineering foundation fields such as railways, highways and bridges, ports, docks, water conservancy, municipal administration, buildings and large equipment.

[0003] For example, a high-strength concrete pipe pile is disclosed in the patent with application number CN202122388193.0. The high-strength concrete pipe pile is designed with inner piles, vertical plates, horizontal plates, first inclined plates and second inclined plates. The first inclined plates and second inclined plates are triangular reinforcements, which can improve the stability and compressive resistance of the concrete pipe pile body and effectively improve the overall strength of the concrete pipe pile body. The design of the first protective layer, the second protective layer and the third protective layer, the first protective layer can make the concrete pipe pile body waterproof and high-temperature resistant.

[0004] However, in actual use, the concrete pipe piles are only reinforced from the inside by a single-layer reinforcement structure. The concrete pipe piles not only have to withstand internal pressure, but also need to withstand the extrusion of external soil. Simply setting up a reinforcement structure inside cannot improve the strength of the concrete pipe pile body. At the same time, the required length of the pipe piles varies according to different needs, which is not convenient for connecting the pipe piles.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Summary of the Invention

The outer sleeve is provided with a plurality of holes which match the positioning posts, and the outer sleeve is provided with a plurality of connecting threads which are connected to the outer sleeve of the fixing plate. The connecting threads are connected to the fixing plates, and the fixing plates are connected to the fixing plates.

[0009] Furthermore, four sets of external positioning mechanisms are evenly and detachably mounted on the first concrete pipe pile and the second concrete pipe pile.

[0010] Furthermore, the external positioning mechanism includes a positioning piece, a cutting edge is integrally provided on the positioning piece, and a cutting edge is provided at one end of the positioning piece and the cutting edge.

[0011] Furthermore, an arc-shaped connecting plate having the same curvature as that of the outer covering steel sleeve is integrally mounted on the bottom of the positioning piece, and positioning through holes are symmetrically mounted on the arc-shaped connecting plate.

[0012] Furthermore, the sealing structure includes a metal sealing ring connected to one end of the concrete pipe pile 1 and the concrete pipe pile 2, and a cavity is provided at the center of the metal sealing ring.

[0013] Furthermore, four mounting bolts are installed on the metal sealing ring, and a sealing gasket is installed on one side of the metal sealing ring located on the mounting bolts.

At the same time, the positioning columns on the concrete pipe pile 1 and the concrete pipe pile 2 are inserted into the limiting holes on the outer metal connecting tube, thereby ensuring the accuracy of the docking of the concrete pipe pile 1 and the concrete pipe pile 2. When the concrete pipe pile 1 and the concrete pipe pile 2 are positioned, the connecting bolts are screwed through the connecting threaded holes through the action of the connecting bolts. And it is threadedly connected with the positioning thread groove to connect and fix the concrete pipe pile one and the concrete pipe pile two. After the connection and fixation are completed, the concrete pipe pile can be inserted into the ground through a pile driver. Through the action of the outer ring and the inner ring of the steel bars in the concrete pipe pile one and the concrete pipe pile two, in conjunction with the outer fastening ring, after pouring concrete from the concrete pouring cavity, the concrete and the outer ring and the inner ring of the steel bars are perfectly connected and matched, which greatly increases its structural strength. In conjunction with the positioning steel bars, the connection strength of the upper and lower adjacent outer rings of the steel bars and the inner ring of the steel bars is enhanced, making it less likely to be broken by the pressure of the soil and the pressure during piling. Finally, in conjunction with the external reinforcement structure, its overall structural strength is improved. Such a device has a simple structure, is convenient for connecting the adjacent concrete pipe piles one and two, and has good stability after connection. At the same time, it enhances the overall structural strength of the concrete pipe piles one and two, making it less likely to be broken and damaged, and the overall pouring production is relatively simple.
