Problems solved by technology

The traditional steel casing guide frame is a cantilever type guide frame, and must be positioned on the platform for construction. On the one hand, the hoisting height of the door crane is required to be greater. On the other hand, it is difficult to control the accuracy of the steel casing and the construction efficiency is low

Abstract

The invention discloses a large-diameter steel protection cylinder three-frame guide frame and auxiliary positioning platform device. The device comprises an auxiliary positioning platform and a three-frame guide frame; the three-frame guide frame is provided with three guide frames and two connecting structures; the three guide frames are connected through the two connecting structures to form awhole; the connecting structures comprise connecting structure vertical rods, connecting structure cross bars and connecting structure inclined supports; the two ends of the connecting structure inclined supports are respectively connected to the middle parts of two adjacent connecting structure cross bars; the other ends of the two connecting structure inclined supports with the same top points are respectively connected to the top points of the two connecting structure vertical rods arranged at intervals; the auxiliary positioning platform comprises auxiliary piles and a guide frame mountingplatform; four auxiliary piles are provided, and are connected through I-shaped steel to form a whole; and the four auxiliary piles are connected through the I-shaped steels to form an auxiliary pileupper-layer structure and an auxiliary pile lower-layer structure. The device has the advantage of greatly improving the plane positions and the verticality precision of steel protection cylinders.

Description

Technical field [0001] The invention relates to the technical field of construction of water structures, and more specifically it is a three-frame guide frame and an auxiliary positioning platform device for a large-diameter steel protective tube. Background technique [0002] During the construction of the highway bridge, the verticality of the sinking of the pile foundation steel protective tube and the deviation of the center position directly affect the smooth formation of the pile and the construction quality of the pile foundation, and affect the lowering of the steel box of the cap. The traditional steel protective tube guide frame is a cantilevered guide frame, and the construction must be positioned on the platform. On the one hand, the hoisting height of the door crane is greater, and on the other hand, the precision of the steel protective tube is difficult to control and the construction efficiency is low. Summary of the invention [0003] The purpose of the present in...
