Concrete bored piles can resist the effects of external forces such as earthquakes and wind while reducing foundation settlement. This method is suitable for various geological conditions, especially soft soil areas.

[0003] However, when existing concrete bored piles are used to reinforce the foundation, the pouring of the pile foundation is usually completed before the pouring of the foundation, which makes the mixing of the two poor. At the same time, the horizontality of the upper surface height of the pile foundation cannot be guaranteed, and further, when the formwork of the foundation is installed, the uniformity of the formwork installation height cannot be guaranteed, thereby reducing the convenience of use. Utility Model Content

[0011] Preferably, a casting hole is opened at the center of the support plate, and the inner diameter of the casting hole is equal to the inner diameter of the guide cylinder, and an overflow hole is opened on the circumference of the support plate.

[0012] Preferably, the support plate is provided with a through hole adapted for the threaded rod, and the overflow hole is located at the diameter of an adjacent through hole, and the axis of the overflow hole and the axis of the through hole are located on the same circular line.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 The utility model provides an embodiment: a building foundation reinforcement pile, comprising:

[0023] A concrete pile tube 1 is provided with a first end cap 2 at the bottom of the concrete pile tube 1, a second end cap 3 is provided at the top of the concrete pile tube 1, a threaded rod 4 is connected to the top of the second end cap 3, a support plate 5 is sleeved on the outside of the threaded rod 4, a nut 6 is connected to the outside of the threaded rod 4 through threads, a guide cylinder 51 is fixedly connected to the bottom of the support plate 5, and the guide cylinder 51 is slidably connected to the inner wall of the second end cap 3, and the support position of the support plate 5 is adjusted by adjusting the position of the nut 6 through the mutual cooperation of the threaded rod 4 and the nut 6, so as to facilitate its height adjustment, thereby ensuring the uniformity of the height of the support plate 5 at different positions, thereby ensuring the uniformity of the foundation poured above, and facilitating the horizontal installation and positioning of the foundation template;

[0024] The steel cage 7 is located inside the concrete pile tube 1 and penetrates to the top of the support plate 5. The steel cage 7 penetrates between the foundation and the pile foundation, so that when pouring concrete, the foundation and the pile foundation can be poured in an integrated manner, thereby improving the reinforcement stability.

[0025] Furthermore, the outer diameter of the concrete pile barrel 1 is equal to the outer diameter of the first end cap 2, the first end cap 2 and the second end cap 3 have the same structure, and the first end cap 2 and the second end cap 3 are symmetrically distributed, and the inner diameter of the concrete pile barrel 1 is equal to the inner diameter of the first end cap 2. By sleeve-fitting the end of the first end cap 2 and the second end cap 3, the high strength of the end of the concrete pile barrel 1 can be improved, and the end of the concrete pile barrel 1 can be prevented from being cracked.

[0026] Furthermore, a support mesh 21 is fixedly connected to the inner wall of the first end cover 2, and the bottom of the steel cage 7 is connected to the support mesh 21. The support mesh 21 can assist in supporting and connecting the steel cage 7 and improve the stability of the casting connection.

[0027] Furthermore, there are six groups of threaded rods 4 distributed around the circumference, and two nuts 6 are connected to the outside of each group of threaded rods 4. The two nuts 6 are respectively located at the upper and lower ends of the support plate 5, and then by adjusting the height of the nuts 6, the height of the support plate 5 inside can be adjusted, thereby improving its flexibility of use.

[0028] Furthermore, a casting hole is opened in the center of the support plate 5, and the inner diameter of the casting hole is equal to the inner diameter of the guide tube 51. An overflow hole 52 is opened on the circumference of the support plate 5. The guide tube 51 slides through the inside of the second end cover 3, so that the poured concrete can accurately enter the interior of the concrete pile tube 1, which plays a good guiding role.

[0029] Furthermore, a through hole adapted to the threaded rod 4 is provided on the support plate 5, and the overflow hole 52 is located at the adjacent through hole diameter, and the axis of the overflow hole 52 and the axis of the through hole are located on the same circular line. Through the setting of the overflow hole 52, the poured concrete can be diverted so that it is wrapped around the outside of the concrete pile tube 1 and the second end cover 3, which not only provides good support for the support plate 5, but also improves the external wrapping strength of the second end cover 3.

[0030] Furthermore, the outer surface of the threaded rod 4 is provided with a horizontal end, and the surface of the horizontal end is provided with scale lines. By providing the scale lines, the position of the nut 6 can be easily adjusted, thereby making the height adjustment of the support plate 5 more convenient.

[0031] Working principle: The concrete pile barrels 1 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be repeated here. When the utility model is in use, first, a hole is drilled in the ground, and then the concrete pile barrel 1 is inserted into the ground, and then the height of the support plate 5 at different positions is adjusted so that the support plate 5 is in the same horizontal plane, and then the foundation template is installed above the support plate 5, and at the same time, the steel cage 7 is inserted into the inside of the concrete pile barrel 1 and positioned, and finally, the foundation and the pile foundation inside the concrete pile barrel 1 are cast simultaneously, so that the foundation and the pile foundation are formed as one piece, and at the same time, the laying of the steel cage 7 is coordinated to greatly improve the connection strength, thereby effectively improving the reinforcement strength of the foundation.
