Problems solved by technology

[0003] Although prestressed centrifugal prefabricated square piles are reinforced against pullout piles, the welding method is still used. After the piles are welded and connected, they need to be naturally cooled for 8-10 minutes before continuing to sink the piles, which wastes a lot

Embodiment Construction

[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0024] see Figure 1-Figure 4a , a mechanical connection structure for connecting prefabricated square piles, mainly composed of a prefabricated square pile end plate 1 and a mechanical connection plate 3 for connecting the end plates. When two prefabricated square piles are docked, use the pile collar 2 on the end plates of the two prefabricated square piles and the four external mechanical connecting plates or use two V-shaped mechanical connecting plates or According to the number of bolts, a plurality of mechanical connecting plates 3 are arranged on each surface to connect with bolts 16, and then the mechanical connecting plates 3 and the screw holes 4 on the pile collar 2 are screwed and connected by bolts 16 until they are connected to th...

Abstract

The invention relates to a mechanical connection structure for splicing precast square piles. An end plate for butting is arranged at an end of a precast square pile to be butted. The mechanical connection structure is characterized in that: a screw hole is formed on a side surface of the end plate, mechanical connection plates are arranged on the side surfaces of the mutually butted end plates, and the mechanical connection plates are connected with the screw holes on the side surfaces of the end plates through bolts so that the butted end plates are fixedly connected. The connection structure can relatively reduce the mechanical connection points, improve the connection reliability, reduce the potential safety hazard of foundation engineering, further ensure the safety of a structure and simultaneously improve the convenience in construction.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a structure used for prefabricated square pile foundation pile connection, especially a structural connection suitable for uplift-resistant foundation piles and a specific construction operation method for this structure. Background technique [0002] With the increasing importance of modern buildings and the diversification of structural forms, the requirements for foundation treatment in construction projects have been continuously improved. Most of the supporting and force-transmitting rods between them are used as permanent pressure-bearing piles, which mainly bear the vertical load. However, there are more and more underground buildings such as underground garages, shopping malls, and pools. The piles commonly used in special occasions such as basements are Pullout piles, in the past few years, many pullout projects used prestressed pipe piles. Due to the di...
