Description:
To overcome the unstable quality, poor durability of the commonly used welded couplings and structural complexity of existing mechanical couplings, an emerging coupling design with simple structure and higher construction efficiency, with application to the construction of drilling and PHC pipe cased piles, is proposed in this paper. The load bearing capacities of the proposed coupling meets well with the requirements of corresponding standards and specifications. Meanwhile, it makes the connection of the piles strictly sealed, which prevents the grouted cement slurry from permeating into the core of the pipe piles and thereby is beneficial to the maintenance of grouting pressure and quality. Finite element method is employed to reveal its bearing mechanism under different load conditions. The load bearing capacity of the above coupling made of steel with different grades is verified, and its main design parameters are optimized, which can provide theoretical basis for its pract...
