Problems solved by technology

However, in this kind of pile connection structure, since each connecting pin interacts separately, it is difficult to ensure that the force of each connecting pin is the same. Therefore, after the prefabricated piles are connected, the pile connection part cannot be guaranteed to meet the force requirements during the stress process.

Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] As shown in the drawings, the prefabricated pile connection structure of the present invention includes an inner hoop 1 sleeved on the periphery of two pile joints that need to be piled to prefabricated piles, and an outer hoop 2 sleeved and fastened on the periphery of the inner hoop 1 . The inner hoop 1 is composed of two semicircles spliced ​​into a ring, and the inner ring of the inner hoop 1 is provided with two radial protruding rings 4, and each of the pile joints that need to be piled to the prefabricated pile is provided with a radial ring 4 on the periphery of the pile joint. The raised ring 4 matches the groove 5 . The outer wall of the inner hoop 1 and the inner wall of the outer hoop 2 are conical table surfaces that match each other, and the serrations 3 that can clamp the inner hoop 1 and the outer hoop 2 are arr...

Abstract

The invention discloses a pile splicing structure for precast piles, which comprises inner hoops (1) and outer hoops (2), wherein the inner hoops (1) are sheathed at the peripheries of two pile splicing parts required to perform pile splicing on the precast piles; the outer hoops (2) are sheathed and fastened onto the peripheries of the inner hoops (1); each inner hoop (1) is formed in a way that two or more than two arc-shaped components are spliced to form a ring; the inner ring of the inner hoop (1) is provided with at least two radial bulge loops (4); and the periphery of each pile splicing part required to perform the pile splicing on the precast piles is provided with a groove (5) matched with the radial bulge loops (4). By adopting the pile splicing structure for the precast piles, the pile splicing among the precast piles is firm, and the pile splicing parts reach the stress requirement.

Description

technical field [0001] The invention relates to the technical field of prefabricated piles, in particular to a prefabricated pile connection structure. Background technique [0002] At present, the pile connection of prefabricated piles in foundation pile construction in my country is mainly a welded structure. Because the welded structure is constructed on site, it cannot meet the needs of cleaning the end face of the end plate, and the electric welding of the groove groove at the joint needs to be performed symmetrically in three layers, and the weld seam needs to be full. The welded pile joints need to cool down naturally before continuous pile sinking, etc., which leads to the unguaranteed welding quality and the weak connection of prefabricated piles, making the joints of prefabricated piles the weakest link of foundation piles. [0003] Therefore, in the prior art, there are very few structures that use mechanical toothing to complete the pile connection of prefabricate...
