Conventionally, when a concrete structure with a crown beam is manufactured on land, a precast concrete pile with a top surface exposed from a reinforcing steel bar is usually selected, and the precast concrete pile is driven into a designated position by adopting a static pressure method; because the construction space on the ground is large, the construction can be performed by adopting a static pressure method, the exposed steel bars at the top of the precast concrete pile can not be damaged and bent, and the exposed steel bars are very convenient to be connected with the steel bar cages of the crown beams in the follow-up process. When the construction position becomes a river course, a static pressure method cannot be adopted, and only a hammering method (such as knocking by an excavator) can be adopted; when the precast concrete pile with the exposed reinforcing steel bars is adopted, the exposed reinforcing steel bars can be flattened due to repeated hammering actions, and the exposed reinforcing steel bars cannot be effectively connected with a reinforcement cage of the crown beam.
Therefore, when the river is constructed, the precast concrete pile without the exposed reinforcing steel bars is usually adopted, after the precast concrete pile is installed in the river, the top of the precast concrete pile is destroyed by the equipment to expose the reinforcing steel bars, so that the operation difficulty is high, the time is long, the exposed reinforcing steel bars and the top surface are uneven, and the construction quality is poor. And because the precast concrete pile is positioned in the river channel, the construction danger coefficient is higher when the top of the precast concrete pile is damaged.
In view of the special limitations of the hydraulic river support construction machine and the requirement that the pile body top is required to be connected with (exposed) steel bars to meet the pouring requirement of the crown beam, the application has a special structure and arrangement (a flush sleeve is arranged in the pile body top) on the pile body top; in the construction application, the anchoring steel bar is directly connected with the sleeve so as to perform crown beam pouring and pile forming structure and appearance integration, and a steel mesh protection sheet for reinforcing the protection of the pile head part against construction impact is arranged on one side of the steel bar cage close to the sleeve; the steel mesh protection sheet and the steel bars and pile head concrete on the steel bar cage are wrapped by the peripheral armatures, so that a new protection for reinforcing the pile head against construction striking is provided.
According to the pile body, the four sleeves 2 are symmetrically arranged on the pile body, the sleeves 2 are of hollow cylindrical structures, the anchoring cavities with the convex cross sections are arranged in the sleeves 2, and the structure can provide enough space, so that the anchoring steel bars 3 can be firmly embedded into the pile body, and the stability is improved; the T-shaped structure of the head of the anchoring bar 3 enables the anchoring bar 3 to be properly installed and firmly anchored in the sleeve, the T-shaped structure providing better load bearing capacity and load distribution. Specifically, the maximum diameter of the head of the anchoring bar 3 is larger than the minimum diameter in the anchoring cavity, the diameter of the middle part of the anchoring bar 3 is smaller than the minimum diameter in the anchoring cavity, the head of the anchoring bar 3 can be embedded and fixed in the anchoring cavity, and the middle part and the tail of the anchoring bar 3 extend out from the tail of the sleeve 2. After the concrete pile is installed in a river channel by adopting a hammering method, the top of the concrete pile is flat and clean, and no protruding exposed structure exists; the steel bars are installed in the sleeve only through threads (very fast and efficient), the steel bars can be connected with the steel reinforcement cage of the crown beam quickly through the newly installed steel bars, the sleeve is tightly connected with the steel bars in the concrete pile, the crown beam formed after casting is tightly connected with the concrete pile, and the connecting surface is smooth.
Pile tip 6 with high penetrating power is arranged at the bottom of the pile body, and pile tip 6 is of a conical structure and plays a guiding role, so that stability of the pile body is ensured, and the pile body is prevented from deviating at the bottom. Specifically, a cylindrical spike 61 is welded in the pile tip 6, the diameter of the spike 61 is greater than or equal to 20mm, and the length of the spike 61 extending from the bottom of the pile tip 6 is greater than or equal to 30mm.
