A rigid pile composite foundation assembled pile cap and its assembling method

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 a rigid pile composite foundation assembled pile cap and an assembling method thereof. Background technique [0002] Soft soil foundation treatment in roadbed is often reinforced by rigid pile composite foundation, which has high efficiency, good effect, and comprehensive cost-effectiveness compared with traditional foundation reinforcement treatment methods such as cushion replacement, cement grouting, and piling preloading. The advantage is that setting a certain size of pile cap 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 connection processing method between the pile cap and the pile body is to expose the main reinforcement bars by b...

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
