At the progresses of technology, at real need, Liuzhou link nurse has study for many years by mechanical Co., Ltd.s by Europe, Develop new-type anchors ask for and at 1997 by Guangxi willow of the Guangxi Zhuang Autonomous Region expressway and road bed strengthen project and phosphorus of Luzhai ammonia chemical fertilizer factory permanent dark base holeses slope Dam strengthen project adopt OVM pressure type,, OVM draw and pigeonhole type who disperses pressure anchor ask for and get good social economic result person who disperse OVM by dam foundation, To ask for anchor whether it is interior propose scientific classification strength state for anchor careless piece,namely: Anchor ask for, OVM pressure type anchor ask for pulling force type, OVM load OVM, OVM load anchor ask for and divide into person who disperse at OVM pulling force disperse, OVM pressure disperse.

So-called OVM ask for structure mean OVM ask for and load anchor ask for the series person who disperse with OVM by pressure type anchor by new-type anchors, Whether in the past commonly used pulling force type anchor ask for and receive strength mechanism rational, anchor careless result fine, considerable looks wider range of application economic benefitses they. These two kinds of anchors are asked for to the weak rock body, especially have irreplaceable function to bear the weight of the soil body permanent reinforcement with low strength , However, among projects and OVM load OVM pressure type anchor ask for person who disperse , especially anchor ask for type who disperses pressure OVM. Fact prove OVM ask for and solve traditional anchors ask for and deposit better by new-type anchors, Satisfy the requests of different type projects. Up till now, OVM new-type anchors are asked for and already gotten a large amount of application.

 Because technical progress, according to actual requirement, LiuZhou state OVM machine limited liability syndicate through much year study, develop new anchor cord amalgamation in 1997 in Guangxi laurel  express highway lap  and road foundation reinforce engineering and deer  phosphorus aminate fattyly plant permanence deeply radical pit and  river bank electricity station bigly bar - bar - radical reinforce engineering adoption OVM compressive force pattern, OVM compressive force dispersion pattern, OVM pull press diversify pattern anchor cord acquisition fair community economy result hereafter, to the cord of anchor press inside anchor  zone suffer towing force status propose science of assorting, scilicet:OVM tensile force pattern anchor cord, OVM compressive force pattern anchor cord, OVM lading dispersion pattern anchor cord, OVM lading dispersion pattern anchor cord again is divided into OVM tensile force dispersion, OVM compressive force dispersion, OVM pull press dispersion pattern anchor cord.
So-called OVM new model anchor cord structure is in reference to OVM compressive force pattern anchor cord sum OVM lading dispersion pattern anchor cord series, they opposite in former in common use of tensile force pattern anchor cord suffer towing force mechanism more reasonable, economic benefit considerable, application more wide.This two kind anchor cord vs weak rock mass, especially bearing power low mass permanence reinforce have can't supersede of action, thereupon, in manyly engineering OVM compressive force pattern sum OVM lading dispersion pattern anchor cord, especially OVM compressive force dispersion pattern anchor cord drive extensive appliance.
Factual proof, OVM new model anchor cord satisfaction every kind of type engineering of solicit.So far, OVM new model anchor cord already receive bulk analysis appliance.
