Problems solved by technology
[0004] In the preparation process of existing concrete piles, the pile hole is adapted to the steel cage. When the foundation soil is relatively soft, it is easy to form sediment in the pile hole. The square pile has low strength, low bearing capacity and pullout resistance

Embodiment 1
[0039] see Figure 1-3 and Figure 6 , a high-strength concrete pile, including a reinforcement cage 1 inserted in the pile hole, the reinforcement cage 1 includes a plurality of outer straight bars 101 and inner stirrups 102 embedded and connected inside and outside, and the plurality of outer straight bars 101 are distributed in a ring On the outside of the multiple inner stirrups 102, the outside of the multiple outer straight bars 101 is provided with a pile hole attachment cage 2, and the pile hole attachment cage 2 includes an annular steel cage 201 attached to the outside of the multiple outer straight bars 101, There are a plurality of conical embedded steel plates 202 embedded in the pile holes on the outside of the annular steel cage 201. The annular steel cage 201 and the inner wall of the pile holes form a first pouring cavity, which is filled with the first concrete layer.
[0040] The inner and outer side walls of the annular steel cage 201 are attached with alk...

The invention discloses a high-strength concrete pile and its pouring process, which belongs to the technical field of concrete pile preparation. It is formed by arranging a pile hole attachment cage and an internal reinforcement body on the inside and outside of the reinforcement cage, and an annular steel cage and a conical embedded steel plate. The pile hole attachment cage is embedded in the pile hole, and the first concrete layer is filled in the first pouring cavity formed by the two to form a solid peripheral reinforcement layer outside the reinforcement cage, and then the reinforcement cage is inserted into the pile hole In the attachment cage, the second concrete layer is filled between the reinforcement cage and the pile hole attachment cage to realize the mechanical bonding of the two, and then an internal reinforcement is placed in the reinforcement cage, and the internal reinforcement includes a hollow injection steel pipe in the middle And the multiple fan-shaped reinforcing pieces distributed on the outside of the hollow injection steel pipe, the third concrete layer is filled between the multiple fan-shaped reinforcing pieces, and the pouring process of embedding and filling from the outside to the inside is used. On the one hand, the concrete piles are not easy to scatter On the other hand, it can effectively improve the bearing capacity and pull-out resistance of solid square piles.
Description
technical field [0001] The invention relates to the technical field of concrete pile preparation, in particular to a high-strength concrete pile and its pouring process. Background technique [0002] In the modern construction industry, foundations and piles are one of the most important parts of construction. Concrete piles are piles made of concrete (including ordinary reinforced concrete and prestressed concrete), which have the advantages of saving wood and steel, durable, and low cost. , has been widely used in the foundation engineering of hydraulic construction, industrial construction, civil construction and bridges, and is also commonly used in anti-skid or water isolation of slope and foundation pit support. [0003] The cross-section of the pile is square, rectangular, circular, etc., and the most commonly used ones are square cross-section piles and circular cross-section piles. Put it into the pile hole, pour concrete, and form a concrete pile after it solidifi...
