[0028] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0029] like Figure 1-3 As shown, the present embodiment provides a protective structure for bridge construction, comprising a plurality of interconnected bridge components 100, with mounting platforms 110 provided on the tops of the two bridge components 100 on both sides, and a vertically arranged anti-throwing net 300 provided on the mounting platform 110, for preventing falling objects such as fallen rocks from falling from the sides of the bridge components 100 during construction onto the railway track below, thereby affecting the driving safety of the railway.

[0030] In order to prevent falling objects such as falling rocks from passing over the anti-throwing net 300, a protective platform 200 is set on the outer walls of the two bridge components 100 on both sides. The protective platform 200 is tilted from bottom to top from the side close to the bridge component 100 to the side away from the bridge structure. Even if falling objects such as falling rocks pass over the anti-throwing net 300 and fall onto the protective platform 200, they will accumulate at the connection between the protective platform 200 and the bridge component 100 due to the tilting effect and cannot fall downwards, thereby improving the protection effect of the construction.

[0031] In order to improve the structural strength of the protection platform 200 , a wooden board layer 210 with a thickness of approximately 2.5 cm is laid on the top of the protection platform 200 , and a steel board layer 220 with a thickness of approximately 3 mm is laid on the wooden board layer 210 .

[0032] In order to improve the waterproof performance of the protection platform 200 , a waterproof canvas layer 230 is provided on the steel plate layer 220 .

[0033] In order to improve the fireproof performance of the protection platform 200 , a fireproof asbestos layer 240 is provided on the waterproof canvas layer 230 .

A fixing screw 600 is screwed from the mounting plate 250 through the first mounting hole and the second mounting hole to realize a detachable connection between the protection platform 200 and the bridge component 100.

[0035] The inclination angle of the protection platform 200 is 100° to 110°, and is preferably set to 104° in this embodiment.

[0036] In order to further improve the driving safety of the railway during the construction process, a protective plate 400 is provided between every two adjacent bridge components 100 , and both sides of the protective plate 400 are connected to the bridge components 100 on the same side.

[0037] Specifically, a connecting plate 500 is provided between two adjacent bridge components 100, and sleeves are pre-embedded on the connecting plate 500 and the bridge component 100. It also includes at least two connecting rods 410 arranged on the protective plate 400. The connecting rods 410 pass through the bridge component 100 and the connecting plate 500 through the sleeve and are detachably connected to achieve the connection and fixation between the protective plate 400 and the bridge component 100.

[0038] The construction steps of the protective platform 200 of the protective structure for bridge construction in this embodiment are as follows:

[0039] 1. Install the protection platform 200 on the outer wall of the bridge component 100;

[0040] 2. Laying a wooden board layer 210 on the protective platform 200;

[0041] 3. Laying the steel plate layer 220 on the wood plate layer 210;
