Polymer composite materials and gabion nets, gabion or active protection nets prepared therefrom

Abstract

The invention belongs to the field of building construction, particularly relates to a polymer composite for outdoor project construction and a gabion mesh, a gabion or an active protecting mesh produced by the polymer composite, and aims to solve the technical problem that the gabion is long in mounting time and difficult in underwater connection with new foundation. The polymer composite comprises, by weight percentage, 33-85% of main material, 4-8% of anti-ultraviolet additives, 6-10% of toughness improving agent and 0-50% of auxiliaries. The polymer composite is high in toughness, high in corrosion resistance, high in fatigue resistance, and the like. The gabion produced by the polymer composite is high in multi-gabion combination strength, capable of achieving underwater connection with new foundation, short in construction cycle, suitable for fast emergency construction, and the like.

Description

technical field [0001] The invention belongs to the application field of polymer composite materials, and in particular relates to a polymer composite material for outdoor engineering construction and a gabion net, a gabion or an active protection net prepared therefrom. Background technique [0002] Gabion nets are mainly used for slope support, foundation pit support, mountain rock surface hanging net spraying, slope vegetation, railway and highway isolation protection barriers, and it can also be made into cages and mesh pads for rivers, dams And seawall anti-scouring protection and reservoir, river closure. The gabion currently used adopts ordinary steel frame, and the gabion net is mainly artificially woven lead wire mesh or machine-woven living net. Put the backfill medium in the steel cage to improve the integrity of the backfill body and increase the erosion resistance of the embankment. [0003] However, metal gabion nets have the following disadvantages: [0004...

AI Technical Summary

Problems solved by technology

[0004] (1) The gradation requirements of the filling in the cage are high, and it is necessary to sort a reasonable block size, otherwise the cage filling process cannot be realized;

[0005] (2) There must be no sediment impurities, otherwise it is difficult to ensure the fullness of the filler;

[0007] (4) Due to the artificially welded steel frame, artificial mesh connection, and manual filling, the construction period is relatively long, which is not suitable for rapid emergency construction;

[0008] (5) The gabion must first be welded on the dry and flat ground on the 5 sides of the gabion, and then filled with filler and then covered and closed. Because the construction is near the water bank, there is no working platform, and the filler should be fixed in place. tougher;

[0009] (6) The strength of the single cage is relatively high, but the integrity and strength of the multi-cage combination are not good
