Rigid pile composite foundation fabricated pile cap and assembling method thereof

Abstract

The invention discloses a rigid pile composite foundation fabricated pile cap and an assembling method thereof. A pile sleeve is arranged at the top end of a rigid pile body, the end, being connectedwith a pile cap plate, of the pile top sleeve is arc, an arc gasket is arranged between the arc end of the pile top sleeve and the pile cap plate, a groove matched with the shape of the arc gasket isformed in the bottom center of the pile cap plate, the arc gasket is separately in contact with the pile top sleeve and the groove, and the arc gasket can separately slide relative to the groove and the pile top sleeve. According to the rigid pile composite foundation fabricated pile cap and the assembling method thereof, general members and materials are adopted, the structure is simple, the durability is high, the mounting is convenient, the assembly process of the pile cap is reduced, the member forming quality is improved, the cost is low, and popularization and use are facilitated.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and relates to an assembled pile cap of a rigid pile composite foundation and an assembly method thereof. Background technique [0002] The soft soil foundation in the subgrade is often reinforced by rigid pile composite foundation. Compared with the traditional foundation reinforcement treatment methods such as cushion replacement, cement grouting, and surcharge preloading, it has high efficiency, good effect, and high comprehensive cost performance. Advantages, setting a pile cap of a certain size at the top of the rigid pile can transfer the embankment load within the cap surface from the soil between the piles to the pile body, thereby improving the bearing efficiency of the rigid pile and better exerting the load effect of the composite foundation. [0003] The traditional method of connecting the pile cap and the pile body is to expose the main stress tendons by breaking the pile ...

AI Technical Summary

Problems solved by technology

This capping method mainly has the following defects: (1) The construction process is cumbersome and complicated, requiring a lot of labor and mechanical equipment, and the construction cost is high and the progress is slow; (2) The quality of the pile is easily affected by the on-site operating environment and construction personnel And the quality is difficult to guarantee, and it is difficult to repair and replace; (3) It is rigidly connected to the pile body. Although the integrity is good, it is prone to cracking and damage at the joint between the pile and the cap, which will affect the bearing performance of the entire composite foundation
