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 accompanying drawings, the prefabricated pile connection structure of the present invention includes a positioning ring 1 prefabricated on the periphery of the pile connection part of the prefabricated pile 4, and a connecting hoop sleeved on the periphery of the two positioning rings 1 that need to be piled to the prefabricated pile 4 2. A plurality of bolts 3 are fastened between the connecting hoop 2 and the positioning ring 1, and the distance between the plurality of bolts 3 is equal. The end of the end plate 5 of the prefabricated pile 4 is provided with a radial protruding ring 6 , and the inner wall of the connecting hoop 2 is provided with a groove 7 for accommodating the radial protruding ring 6 . The connecting hoop 2 is formed by splicing three arc parts with a radian of 120° into a circle. Of cour...

Abstract

The invention discloses a preformed pile connecting structure which comprises positioning rings (1) and connecting hoops (2). The positioning rings (1) are preformed at the periphery of the connection parts of preformed piles (4); the connecting hoops (2) are sleeved at the periphery of the two positioning rings (1) of the two preformed piles (4) needing to be connected; and the connecting hoops (2) and the positioning rings (1) are fastened by a plurality of bolts. Due to the adoption of the preformed pile connecting structure, the preformed piles can be connected firmly, and the connection parts of preformed piles can meet the force bearing 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...
