Pile cap for single pile bearing capacity detection of CFG pile and using method thereof

Abstract

The invention relates to a pile cap for single pile bearing capacity detection of a CFG pile. The pipe cap is used for bearing the CFG pile with a single pile bearing capacity of less than or equal to1000 KN. The pile cap comprises a steel protection barrel and a steel plate, and is characterized in that the steel protection barrel is a round hollow steel pipe matched with the end head of the CFGpile, and the steel pipe can movably sleeve the end head of the CFG pile to form the pile cap; the inner wall of the periphery of the hollow steel pipe abuts against the outer side of the end head ofthe CFG pile, and is filled with fine sand in the middle; the steel plate is a circular steel plate; and the round steel plate is centrally placed on the top of the fine sand on the upper opening ofthe steel pipe. The pile cap for the single pile bearing capacity detection of the CFG pile has the advantages that the pile cap is simple in structure, convenient to manufacture, safe and reliable indetection engineering quality, the pile inspection period is greatly shortened, and thus the construction total period is reduced, the material price of the pile cap is low, and the pile cap can be reused, and the construction cost is reduced.

Description

technical field [0001] The invention relates to a pile cap of a CFG pile, in particular to a pile cap used for testing the bearing capacity of a single pile of a CFG pile and a using method thereof. Background technique [0002] CFG piles are poured with plain concrete, and the CFG pile head is likely to crack or break when testing the bearing capacity of a single CFG pile, which may easily cause unqualified CFG pile test results and affect the quality of CFG piles. [0003] Therefore, when testing the bearing capacity of a CFG pile single pile, the pile head takes strengthening measures. One is to press the pile cap reinforcement cage into the pile head after the concrete pouring of the pile body is completed, but the construction of pressing the reinforcement cage is difficult; the other is to press the reinforcement cage into the pile head. After the concrete strength of the pile body is reached, the pile is cut to make a pile cap again. This method requires maintenance t...

AI Technical Summary

Problems solved by technology

Therefore, the grouting material pile cap of this method still needs maintenance time, and there is also the problem that the detection cycle is long, which affects the construction period

[0005] Therefore there is above-mentioned inconvenience and problem in the pile cap of known CFG pile
