The whole framework is composed of frame columns and frame beams, and the secondary frame columns and the secondary frame beams are combined and arranged above the frame beams, so that the rigidity and the stability of the column section can be increased.
Further, the two layers of protective nets are respectively connected with the prefabricated columns.
Furthermore, protective net connecting rails are arranged on two sides of the two layers of protective nets and can be mutually clamped with the rails.
Furthermore, after the rolling stones with smaller diameters fall onto the protective net, the connecting rails of the inner flexible protective net can be attached to the prefabricated rails more tightly.
Further, when the major diameter rolls the stone and falls down striking prefabricated post, the protection bamboo can play certain cushioning effect, can consume and roll stone partial energy to alleviate the striking that prefabricated post bore, and the bamboo can prevent effectively that prefabricated post from damaging in the prefabricated post outside rather than laminating.
Furthermore, a guest is selected as the flexible protective net, and a transparent PA is selected as the rigid protective net.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the middle prefabricated column of the utility model is made of steel, is convenient for large-scale production field assembly, can avoid using a large amount of concrete, and can be more effectively and conveniently transported and installed; the prefabricated column can reduce the calculated length of the prefabricated column through the secondary frame column and the secondary frame beam, strengthen the overall rigidity and stability, dissipate partial energy, have enough rigidity and better stability,
2. the bamboo is a gramineae plant that the quantity is many in the four-river region, and growth cycle is short and in large quantity, and its bending strength is also higher, and protection bamboo and prefabricated post's combination, the striking of keeping off the stone that rolls that can be better to, planting the bamboo at prefabricated post periphery, not only can cushion the striking, protection prefabricated post is suitable in addition to the appearance, and pleasing to the eye degree is higher, and it is natural to laminate more.
3. The protective net can be disassembled, so that after-disaster sediments can be cleaned conveniently, and later maintenance and repair can be carried out.
4. The protection network comprises one deck flexible protection network and one deck rigidity protection network, and when the rock rolling falls down, the inboard flexible net can play certain cushioning effect, reduces the outside rigidity protection network because of the damage that the striking caused, and rigidity protection network rigidity is great, with prefabricated post global function, more effectual stone rolling of blocking.
5. The flexible protective net adopts gabion, and has strong corrosion resistance, high strength and very good wear resistance; the rigid protective net is made of transparent PA, and the transparent PA has good tensile strength, impact strength, rigidity, wear resistance, chemical resistance, surface hardness and other properties. The two-layer protection network requires less to the environment, and adaptation that can be better is in comparatively abominable environment, and natural state life cycle is longer to two-layer protection network combined action, better performance blocks the ability.
