Abstract

The invention discloses prefabricated piles, a connecting structure of the prefabricated piles and a construction method of the connecting structure. The prefabricated piles include pile bodies and end head plates at the two ends, wherein a plurality of connecting cylinders are arranged in the end head plates in an embedded mode, and the two ends of a main rib penetrate through the connecting cylinders and extend outwards; the connecting cylinders are filled with colloids in a sealing mode, and the whole pile bodies have no metal materials; ribs and the pile bodies can be effectively preventedfrom being eroded by chloride ions in corrosive environments such as seawater; the connecting structure of the prefabricated piles comprises columnar connecting bodies tightly connected between the prefabricated piles, and sleeves are arranged on the columnar connecting bodies in a sleeving mode; and gaps between the sleeves and the side walls of the columnar connecting bodies and the connectingcylinders are all filled with the colloids, the connecting structure can be tightly connected between the two prefabricated piles, the connection is reliable, and the function of corrosion resistanceand high-strength connection can be realized. The construction method of the connecting structure comprises the steps that the columnar connecting bodies and the sleeves are installed, and the installation is convenient.

Description

technical field

[0001] The invention belongs to the technical field of pile body connection, and in particular relates to a prefabricated pile, a connection structure of the prefabricated pile and a construction method of the connection structure. Background technique

[0002] Domestic prefabricated pile connections based on steel bars mainly include welding connections, mechanical connections, and hoop connections. Among them, the welding connection method in engineering is widely used because of its fast construction speed. However, for prefabricated piles based on carbon fiber materials, the characteristics of carbon fiber materials cannot be welded and extruded, so common connection forms in engineering cannot be applied. With the application of carbon fiber material reinforced prefabricated piles in the fields of foundation pit engineering, high pile wharf and slope engineering, the bearing performance of prefabricated piles and their joint connections has become the ke...
