[0017] In this embodiment, the embedded steel bars of the crash barrier 1 and the main beam flange plate 2 are connected by longitudinal steel bars 10. At the same time, the two sides of the crash barrier 1 and the main beam flange plate 2 are connected by the outer support block 6 and the protective layer template 5 to form an epoxy resin mortar pouring cavity 11. Epoxy resin mortar is poured into the epoxy resin mortar pouring cavity 11 and cured for 6 hours. Then, the inlet pipe 7, the outlet pipe 9 and the protective layer template 5 are removed, thereby completing the installation of the prefabricated crash barrier. Epoxy resin mortar has the advantages of early strength and high durability. The curing time of epoxy resin mortar is significantly shortened, and it has strong corrosion resistance.

[0018] The epoxy resin mortar casting cavity 11 is provided with an inlet conduit 7 and an outlet conduit 9. The end of the inlet conduit 7 is provided with a funnel 8. The outer diameter of the inlet conduit 7 is 20mm~30mm and the wall thickness is 1mm~2mm. The top of the inlet conduit 7 is 10cm~30cm higher than the top of the outlet conduit 9.

[0019] In this embodiment, the inlet conduit 7 is inserted into the reserved hole of the anti-collision wall 1. The outer diameter of the inlet conduit 7 is 25mm and the wall thickness is 1mm. The funnel 8 is inserted into the inlet conduit 7, and the epoxy resin mortar is poured into the funnel 8. The epoxy resin mortar is gradually poured into the cavity 11 along the inlet conduit 7.

Excess air is discharged from the outlet conduit 9 until the epoxy resin mortar is gradually discharged from the outlet conduit 9. The construction method for the aforementioned rapid assembly crash barrier structure includes the following sequential steps: Step 1: Fabricate and install 3 U-shaped reinforcing bars for the flange; Fabricate the main beam flange plate 2. The thickness of the thinnest part of the edge of the main beam flange plate 2 is 150mm. Embed the flange U-shaped steel bar 3 in the main beam flange plate 2. The height of the flange U-shaped steel bar 3 exposed above the main beam flange plate 2 is 15cm. Step Two: Construct and Install Crash Barrier 1 The crash barrier 1 is fabricated and installed. The outer support block 6 of the crash barrier 1 is supported on the flange plate 2 of the main beam. The crash barrier U-shaped steel bar 4 is embedded in the crash barrier 1. The height of the crash barrier U-shaped steel bar 4 protruding from the crash barrier 1 is 15cm. The flange U-shaped steel bar 3 and the crash barrier U-shaped steel bar 4 embedded in the crash barrier are tied together with the longitudinal steel bar 10. The diameter of the bottom longitudinal steel bar 10 is 16mm.

[0020] Step 3: Create and install the protective layer template 5 The protective layer template 5 is fabricated and installed so that it fits only the position of the protective layer to be poured. The protective layer template 5 is a steel template with a thickness of 2mm. The anti-collision wall 1, the outer support block 6, the main beam flange plate 2 and the protective layer template 5 together form the epoxy resin mortar pouring cavity 11.
