Description

Technical Field

[0001] The utility model relates to the technical field of large-diameter pile and cap connection structure, in particular to a large-diameter pile and cap connection structure. Background Art

[0002] In pile foundation design, when large diameter piles (design diameter greater than or equal to 800mm) are used, cast-in-place reinforced concrete piles are generally used, and the length of the pile top embedded in the cap is 100mm. The pile reinforcement is anchored into the cap by no less than 35 times the diameter of the reinforcement. The existing device still has some defects; for example;

[0003] For example, a large-diameter pile and cap connection structure with announcement number CN220035487U includes two foundation piles, and the multi-pile cap foundation is provided with cap reinforcement inside. The top outer surfaces of the two foundation piles are provided with a concave-convex rough surface layer, and the inner surfaces of the two foundation piles are provided with a number of pile body reinforcements and shear-resistant connecting short reinforcements. The large-diameter pile and cap connection structure can reduce the thickness of the cap reinforcement protection layer, reduce the foundation thickness, and improve the bearing capacity by providing a 50mm reinforcement protection layer, shear-resistant connecting short reinforcements, a concave-convex rough surface layer, and coating structural interface adhesive. This solves the problem that according to existing specifications, for large-diameter piles, the length of the pile embedded in the cap should not be less than 100mm, resulting in the thickness of the reinforcement protection layer at the bottom of the cap reaching 100mm, which has an adverse effect on the cap's bending, shear, and punching resistance, and may cause cracking of the concrete at the bottom of the foundation.

[0004] The above device has some problems. The device is cumbersome to use, and the connection effect between the diameter pile and the pedestal is poor. After the connection, the fixing effect of the pedestal is not good during use. The pedestal may tilt or deviate during use.

[0005] Therefore, we proposed a large-diameter pile and cap connection structure to solve the above-mentioned problems. Utility Model Content
