Mechanical connection structure used for uplift pile foundation and connection method thereof

Abstract

The invention discloses a mechanical connection structure used for an uplift pile foundation. The mechanical connection structure comprises circular end plates which are fixedly arranged on two uplift pile heads respectively; a plurality of cambered mechanical connection clamps are clamped outside the two circular end plates at the joint parts of the uplift pipe heads; and the cambered mechanical connection clamps are fixedly connected to the circular end plates by a plurality of screws so that upper and lower uplift piles are connected together. The invention aims to overcome the shortages in the prior art, and provides the mechanical connection structure which has the characteristics of simple structure, capability of fixedly connecting two uplift piles quickly, safety and reliability.

Description

technical field [0001] The invention relates to a mechanical connection structure for uplift-resistant pile foundations; the invention also relates to a method for connecting uplift-resistant piles using the mechanical connection structure. Background technique [0002] With the improvement of the importance of modern buildings and the continuous increase of building height, higher requirements are placed on the bearing capacity of the foundation. The natural foundation can no longer bear the load from the upper building, and concrete piles are used to make The foundation piles of the foundation are formed by pressing the piles into the ground with a pile driver to allow the upper part of the foundation piles to carry the building. In the past, the concrete pipe pile foundation of building construction mainly bears the vertical compressive load, but at present, many pile foundations have to bear the vertical compressive load and the vertical pull-out load at the same time. ...

AI Technical Summary

Problems solved by technology

Due to the difference in the level of pile foundation construction units and personnel on site, the quality of welding between pile heads and pile heads is quite different. The quality of welding directly affects the use of uplift piles, causing safety hazards to the project

On the other hand, this welding method takes a long time, which affects the progress of the project and increases the workload of the construction personnel.

Because after the pile head is welded to the pile head, it takes 10 to 15 minutes to wait for the problem at the welding point to cool down before proceeding to sink the pile, which wastes a lot of time and affects the efficiency of construction

At the same time, many pile foundation construction workers continued to sink the piles without waiting for the weld to cool down, which reduced the quality of the weld.
