A multi-level guide bracket for oblique insertion and driving of ultra-long diameter piles

Abstract

The invention discloses a multistage guiding support for oblique inserting piling of a super long and large diameter pile, and relates to the field of bridge pile foundation construction. The multistage guiding support comprises a main truss, a plurality of slide beams and a plurality of supporting and guiding components, wherein the main truss comprises two symmetrical triangular frames which are arranged at intervals, and a plurality of connecting rods are connected between the triangular frames; the top end, the middle and the bottom of the main truss are each provided with two parallel slide beams, and the supporting and guiding components are movably fixed to the slide beams at the top end, in the middle and at the bottom of the main truss, so that a channel for the pile to be subjected to inserting piling is formed. The multistage guiding support can effectively resist horizontal force generated in the inserting piling process of the pile, and meet the construction requirement of multi-section piles.

Description

Technical field [0001] The invention relates to the field of construction of bridge pile foundations, in particular to a multi-level guide support for the oblique insertion and driving of super long and large diameter piles. Background technique [0002] At present, in the construction of bridges, the construction method for the insertion and driving of oblique precast piles and steel pipe piles is generally as follows: use conventional frame structure guide brackets, which generally set up and down guides along the height direction, and set jacks in the guides , Adjust and control the angle and position of the precast pile or steel pipe pile to be inserted through the jack. However, for super-long and large-diameter precast piles or steel pipe piles, when conventional guide supports are used for inserting construction, because the conventional guide supports do not have good resistance to inserting oblique precast piles and steel pipe piles The super-long precast piles or steel...

AI Technical Summary

Problems solved by technology

However, for super-long and large-diameter prefabricated piles or steel pipe piles, when using conventional guide brackets for insertion construction, because conventional guide brackets do not have good resistance to inserting oblique prefabricated piles and steel pipe piles The horizontal force generated, and super-long prefabricated piles or steel pipe piles need to be divided into two sections for construction, and the conventional guide bracket does not have the conditions for the butt joint construction of the second section of steel piles. And large-diameter prefabricated piles or steel pipe piles for oblique insertion construction
