Description

Technical Field

[0001] This utility model relates to the field of building pile foundation technology, specifically a building support pile foundation structure. Background Technology

[0002] A deep foundation consisting of piles and pile caps connecting the pile tops, or a single pile foundation consisting of columns connected to the piles, is simply called a pile foundation. If the entire pile body is buried in the soil and the bottom surface of the pile cap is in contact with the soil, it is called a low pile cap pile foundation; if the upper part of the pile body is exposed above the ground and the bottom of the pile cap is above the ground, it is called a high pile cap pile foundation.

[0003] Existing reinforcement structures simply use steel bars and concrete to solidify inside the foundation pit to reinforce the bottom of the pile cap, resulting in poor fixing strength and low stability. Therefore, we propose a building support pile foundation structure. Utility Model Content

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figures 1-5 As shown, the present invention provides a technical solution: a building support pile foundation structure, comprising: a pile foundation cylinder 1; the pile foundation cylinder 1 is arranged vertically inside the foundation pit 6, a concrete-cast foundation 2 is provided at the top of the pile foundation cylinder 1, and a steel cage 3 extending through to the top of the foundation 2 is provided inside the pile foundation cylinder 1, a plurality of reinforcing nail modules 5 are provided on the side wall of the pile foundation cylinder 1 and inserted into the soil inside the foundation pit 6, and a pile driver vibrator 7 is provided inside the pile foundation cylinder 1, the pile driver vibrator 7 being used at least to insert the reinforcing nail modules 5 through the pile foundation cylinder 1 into the soil of the foundation pit 6.

[0022] In this embodiment, the structure includes: a pile foundation cylinder 1; the pile foundation cylinder 1 is multi-sectioned, each section having the same specifications, and the multiple sections of the pile foundation cylinder 1 are arranged vertically. The pile foundation cylinder 1 can be a precast structure. During pile foundation construction, after the foundation pit 6 is excavated, the pile foundation cylinder 1 is placed one by one inside the foundation pit 6. Alternatively, the pile foundation cylinder 1 can be cast on-site inside the foundation pit 6, that is, the foundation pit 6 is excavated first, and then steel bars and formwork are laid around the inner circumference of the foundation pit to realize the pouring of concrete. After the construction of each section of the pile foundation cylinder 1, the operation of the reinforcement nail module 5 and the grouting between the pile foundation cylinder 1 and the foundation pit 6 are carried out. These steps are repeated in sequence to form a complete pile foundation construction. Finally, the pile cap 2 is constructed on top of the pile foundation.

[0023] In this embodiment, the pile foundation cylinder 1 is arranged vertically inside the foundation pit 6. Several insertion holes 4 are provided on the inner wall of the pile foundation cylinder 1. The insertion holes 4 are pre-processed on the inner wall of the pile foundation cylinder 1. The reinforcing pin module 5 is inserted into the insertion hole 4. The insertion hole 4 is inclined downward. The inclination angle of the insertion hole 4 can be set to 45 degrees downward, thereby improving the connection strength between the pile foundation cylinder 1 and the foundation pit 6 and ensuring the stability of subsequent pile foundation construction.

[0024] In this embodiment, a concrete-cast foundation 2 is provided at the top of the pile foundation cylinder 1, and a steel cage 3 is provided inside the pile foundation cylinder 1, extending to the top of the foundation 2. The concrete is poured for the top foundation 2 by using the steel cage 3 inserted into the pile foundation cylinder 1, so that the foundation 2 and the pile foundation form an integral structure, thereby achieving stable support for the building on it.

[0025] In this embodiment, a number of reinforcing nail modules 5 are provided on the side wall of the pile foundation cylinder 1 and inserted into the soil inside the foundation pit 6. The reinforcing nail module 5 includes a column 51, which is inserted into the hole 4. The upper end of the column 51 is provided with an integrally formed end head 52. The end head 52 allows the pile driver vibrator 7 to contact it. As the pile driver vibrator 7 moves downward, the column 51 is driven into the soil inside the foundation pit 6 one by one, realizing the fixed connection between the pile foundation cylinder 1 and the foundation pit 6. The lower end of the column 51 is provided with a pointed tip 56. The pointed tip 56 structure makes it easier for the column 51 to be inserted into the foundation pit 6, which is convenient for construction. The column 51 has a through core tube 54 inside, and the end 52 has a threaded hole 53 inside. A conical hole 55 is provided between the threaded hole 53 and the core tube 54. The core tube 54, the conical hole 55 and the threaded hole 53 can be used to inject quick-drying mortar into the gap between the pile foundation cylinder 1 and the foundation pit 6 before pouring concrete inside the pile foundation cylinder 1. This improves the stability of the pile foundation cylinder 1 inside the foundation pit 6. The threaded hole 53 can better match the end connection for conveying mortar and realize the conveying of mortar.

[0026] In this embodiment, a pile driver vibrator 7 is installed inside the pile foundation cylinder 1. The pile driver vibrator 7 is used at least to insert the reinforcing nail module 5 through the pile foundation cylinder 1 into the soil of the foundation pit 6. The pile driver vibrator 7 includes an impact core 71, and an impact plate 72 is provided at the bottom end of the impact core 71. The impact core 71 drives the impact plate 72 to descend rapidly, and the impact plate 72 impacts the end 52 of the column 51, thereby causing the column 51 to be inserted into the foundation pit 6. The outer surface of the impact plate 72 is a sloping structure. A lifting ring 73 is provided at the top of the impact core 71 to facilitate the lifting and lowering movement of the impact core 71.
