Problems solved by technology

[0006] The purpose of the present invention is to provide an integrated jacking steel structure bridge and its construction method to solve the problem of inconvenient disassembly and replacement of the anti-throwing net when the anti-throwing net existing in the prior art is damaged during construction. At the same time, there will be a risk of debris falling from a high altitude during the disassembly process, which will interfere with the traffic at the bottom of the bridge

Embodiment 1

[0032] like Figure 1 - Figure 4 , The integrated steel bridges pushing the present invention, including a temporary pushing holder 1, a top pushing the temporary holder 2 is mounted pushing device, said pushing means 2 is provided to the top steel structure continuous beam 3, 3 on both sides of the continuous beam structures 4 connected to the anti-polishing; the anti-polishing 4 includes a base structure 5 is connected to both sides of the continuous beam 3, the base 5 at one end defines a mounting cavity, the mounting motor chamber 6 is mounted, via a shaft of the motor 6 to the top of the retractor 7 with an anti-cast network 8, the other end of the base 5 is rotatably connected to the pawl by the coil spring 9, the other end of the anti-roll cast web 8 closing rod 9 in turn sidewall; in operation, the prior art anti-cast net 8 is fixed by bolts 8 anti-cast net framework, installation is relatively time-consuming, and when the damage prevention cast web 8 appear in the construc...

Embodiment 2

[0041] like Figure 5 As shown in the upper panel 21 defines a set of leakage hole 31, the baffle 32 is connected to the elastic film 16 on the side wall between the pressure chamber 21 and the block 19 stretching, the elastic film 32 and the leak hole at a position corresponding to block 31 is connected with a block 33, block 33 to the top of the connector block extends into the interior of the leakage to the positioning holes 31 34; operation, the leakage holes 21 provided on the baffle 31 can be made rainwater at the funnel-shaped cavity 20 to the interior of the pressure chamber fast bus 16, while when the telescopic water-swellable block 19, then block 19 telescopically movable tip 32 can be pressed upward movement of the elastic film and the elastic film 32 such that the sealing block 33 positioned in the positioning rod 34 and the leak hole 31 at an accurate motion to the leakage hole 31, hole 31 for closure and leakage, so that the shutter 21 is formed integrally in one pie...

Abstract

The invention belongs to the technical field of bridge engineering, and particularly relates to an integrated pushing steel structure bridge and a construction method thereof. The integrated pushing steel structure bridge comprises a temporary pushing support, a pushing device is installed at the top end of the temporary pushing support, a continuous beam of a steel structure is arranged at the top end of the pushing device, and anti-throwing structures are connected to the two sides of the continuous beam; the anti-throwing structure comprises bases connected to the two sides of the continuous beam, a mounting cavity is formed in one end of each base, a motor is mounted in each mounting cavity, an anti-throwing net is wound at the top end of each motor through a rotating shaft, a rotating rod is rotationally connected to the other end of each base through a coil spring, and the other end of each anti-throwing net is wound on the side wall of the corresponding rotating rod. According to the invention, the anti-throwing net can be replaced conveniently and rapidly, the damaged anti-throwing net does not need to be disassembled and replaced in a time-consuming and labor-consuming mode, meanwhile, high falling objects generated in the replacement process of the anti-throwing net can be reduced, and interference of bridge construction on traffic is reduced.

Description

Technical field [0001] The present invention belongs to the technical field of bridge engineering, and specifically involves integrated steel structural bridge and its construction method thereof. Background technique [0002] For bridges across the highway / railway, the bridge is generally used, and the steel box beam structure is generally used, and the bridge is used as an effective construction method. When the traditional top push method, the main structure of the steel box beam is first pushing, and the rest of the bridge area, such as the anti-collision guardrail, anti-thrombinal network, etc., the steel box beam main structure is pushed into place. Construction on the bridge, which inevitably performs a template installation, concrete pouring, steel structure welding, etc., there is a construction risk of high-altitude pendant, and there is no small interference on traffic demand during the construction of bridge. . [0003] There are also technical solutions for steel s...
