Embodiment Construction

[0045] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0046] Such as figure 1 As shown in the figure, a rapid construction method for steel trestle bridges, first of all, the steel pipe piles are inserted and driven by crawler cranes and vibratory hammers as pile foundations and pier columns, and the steel pipe piles are connected as a whole by welding parallel channel steel; secondly, the pile top longitudinal beams are installed , beams, Bailey beams, lay horizontal distribution beams and weld them firmly; lay vertical distribution beams ag...

Abstract

The invention relates to the technical field of bridge construction, in particular to a steel trestle rapid construction method which comprises the following steps that S1, a crawler crane is matchedwith a vibratory hammer to drive steel pipe piles in an inserted mode to serve as a pile foundation and a pier stud, and parallel connection channel steel is welded between the steel pipe piles to beconnected into a whole; S2, pile top longitudinal beams, cross beams and bailey beams are installed, and transverse distribution beams are laid and firmly welded; S3, the longitudinal distribution beams are laid again, steel plates with the thickness of 10 mm are laid, and the steel plates and the distribution beams are firmly welded to form a bridge deck; and S4, finally, protective barriers anda safety protection facility are arranged. The problems that an existing steel trestle construction method is complex in procedure, large in workload and low in working efficiency are solved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a rapid construction method for a steel trestle bridge. Background technique [0002] During the construction of the steel trestle bridge, the amount of welding on site is large and the welding conditions are poor, which has become an important factor restricting the rapid construction of the steel trestle bridge. Most of the existing steel trestle construction methods are that the crawler crane cooperates with the vibrating hammer to insert and drive the steel pipe piles, and the construction is pushed forward step by step. The specific construction process is as follows: first set up a special steel pipe pile insertion guide frame, after the steel pipe pile insertion is completed, the operator cuts the excess length of the steel pipe pile at the front end of the piling guide frame, welds the pile cap, and then removes the steel pipe pile Insert and drive the guide ...
