An auxiliary pile locking structure

Abstract

This utility model relates to the field of auxiliary pile installation technology and discloses an auxiliary pile locking structure, including: multiple C-shaped locking buckles connected to the outside of the auxiliary pile, the central axis of the auxiliary pile being parallel to the central axis of the C-shaped locking buckles, and the central axes of the multiple C-shaped locking buckles coinciding; a seismic buffer gap is formed between two adjacent C-shaped locking buckles; a supporting steel plate is symmetrically arranged on the surface of each C-shaped locking buckle, and the supporting steel plate is connected to the surface of the auxiliary pile. This auxiliary pile locking structure, by designing the C-shaped locking buckles in a spaced-out manner rather than a traditional continuous form, allows the seismic buffer gap formed between adjacent C-shaped locking buckles to act as a deformation buffer zone, enabling the C-shaped locking buckles to undergo certain plastic deformation and displacement under strong vibration conditions, effectively absorbing and dissipating energy, avoiding brittle failure caused by stress concentration, and improving the overall seismic performance and safety of the pile support system.

Description

Technical Field

[0001] This utility model relates to the field of auxiliary pile installation technology, specifically an auxiliary pile locking structure. Background Technology

[0002] In the foundation construction of building projects, port terminals, bridges, etc., it is often necessary to install auxiliary piles and splice them with the main engineering piles. The purpose of this splicing is usually to stabilize the main engineering piles so that subsequent concrete pouring, equipment installation or foundation pit support can be carried out. C-shaped steel buckles are installed between adjacent auxiliary piles for connecting adjacent auxiliary piles.

[0003] Traditional locking structures typically consist of C-shaped steel buckles welded continuously to the surface of auxiliary piles. During construction, auxiliary piles need to be reused and are frequently subjected to hammering vibrations. The rigid connection of the traditional C-shaped locking structure lacks a buffer mechanism and is prone to brittle failure due to stress concentration, failing to guarantee the overall safety of the support system. Furthermore, the traditional C-shaped locking buckle is only connected to the auxiliary pile through a weld. Under long-term, severe vibration loads, the weld is prone to fatigue cracking, causing the C-shaped locking buckle to fall off, resulting in the failure of the locking structure and posing a safety hazard. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an auxiliary pile locking structure, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: an auxiliary pile locking structure, comprising: multiple C-shaped locking buckles connected to the outside of the auxiliary pile, wherein the central axis of the auxiliary pile is arranged parallel to the central axis of the C-shaped locking buckles, and the central axes of the multiple C-shaped locking buckles coincide;

[0006] An anti-seismic buffer gap is formed between two adjacent C-type locking buckles;

[0007] Each of the C-type locking buckles is symmetrically provided with a supporting steel plate, and the supporting steel plate is connected to the surface of the auxiliary pile;

[0008] The surface of the C-type locking buckle has multiple cylindrical holes along the central axis, and the inner wall of the cylindrical holes is connected to a connecting steel column. One end of the connecting steel column passes through the cylindrical hole in sequence and is connected to the surface of the auxiliary pile.

[0009] Preferably, the distance between two adjacent cylindrical holes is 2m, and the diameter of the cylindrical hole is 8cm.

[0010] Preferably, the surface of the connecting steel column is fully welded to the inner circumference of the cylindrical hole, and the end of the connecting steel column is fully welded to the surface of the auxiliary pile.

[0011] Preferably, the surface of the supporting steel plate is fully welded to the surface of the auxiliary pile on one side, and the surface of the supporting steel plate is fully welded to the surface of the C-type locking buckle on one side.

[0012] Preferably, the thickness of the supporting steel plate is equal to the thickness of the C-type locking buckle, and the length of the supporting steel plate is equal to the length of the C-type locking buckle.

[0013] Preferably, the C-type locking buckle is 10m long and 18mm thick.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The auxiliary pile locking structure uses a C-shaped locking design with multiple spaced intervals instead of the traditional continuous form. The seismic buffer gap formed between adjacent C-shaped lockings acts as a deformation buffer zone, allowing the C-shaped lockings to undergo certain plastic deformation and displacement under strong vibration conditions. This effectively absorbs and dissipates energy, avoids brittle failure caused by stress concentration, and improves the overall seismic performance and safety of the pile support system.

[0016] 2. This auxiliary pile locking structure uses supporting steel plates and connecting steel columns. The two supporting steel plates support and fix the C-shaped locking buckle, while the connecting steel column passes through the C-shaped locking buckle and is welded to the auxiliary pile. The surface of the connecting steel column is fully welded to the inner wall of the cylindrical hole. The C-shaped locking buckle has multiple anchoring points. The C-shaped locking buckle is double-fixed by supporting steel plates and connecting steel columns, which improves the resistance of the C-shaped locking buckle to vibration and shear force caused by repeated hammering, prevents the C-shaped locking buckle from falling off the auxiliary pile, and ensures the durability of the structure and construction safety.
