Ultra-long lock catch steel pipe pile guiding and positioning support and using method thereof

Abstract

According to the super-long lock catch steel pipe pile guiding and positioning support and the using method thereof, an upper-layer guiding frame positioning system and a lower-layer guiding frame positioning system are formed by correspondingly arranging a top guiding frame and a bottom guiding frame, and an arranged vertical position adjusting mechanism can accurately adjust the position of the whole guiding frame in the vertical direction; the lock catch steel pipe pile, especially a super-long lock catch steel pipe pile, is ensured to be in a precision controllable and adjustable state in the driving process, when the lock catch steel pipe pile is guided and positioned, the first positioning piece and the second positioning piece are matched with the C-shaped lock catch and the T-shaped lock catch on the corresponding sides of the lock catch steel pipe pile respectively, the positioning precision of the lock catch steel pipe pile is ensured, and the positioning accuracy of the lock catch steel pipe pile is improved. According to the steel cofferdam, lateral distortion and lateral displacement deviation are avoided, the rubber cushion blocks are installed on the inner sides of the first positioning pieces, the buffering and protecting effects are achieved in the sinking process of the steel cofferdam, deformation of a main body structure of the steel cofferdam is avoided, in addition, an assembled structure is adopted, production and installation are convenient, and replacement can be conducted according to different steel cofferdam structural forms.

Description

technical field [0001] The invention relates to the technical field of positioning and guiding of bridge engineering cofferdams. More specifically, the present invention relates to a guide positioning bracket for an ultra-long locking steel pipe pile and a method for using the same. Background technique [0002] In recent years, with the improvement of China's domestic infrastructure and the rapid development of various projects, the use of steel sheet piles is also increasing. Steel sheet piles are now very popular and widely used in other construction fields besides harbors, rivers and roads. With the increasing trend of bridge construction in deep water areas, deep mountains and other regions, the penetration depth of steel cofferdams is getting deeper and deeper, and steel cofferdams with combined structures are emerging one after another. Among them, there are still the following technical difficulties in the construction process of the super-long steel pipe pile coff...
