Description
Technical field
The invention belongs to field of engineering technology, be specifically related to a kind of combined type Recyclable anchor rope structural member and application thereof.
Background technology
In recent years, domesticly there occurs repeatedly great earthquake, as Wenchuan County in Sichuan, Yushu district, Qinghai, the Zhang County earthquake of Minxian County, Gansu etc. bring huge loss to the life of the people and property, therefore the protection against and mitigation of earthquake disasters situation of China is very severe.At present, prestress anchorage cable engineering protection limit (cunning) slope in water conservancy and hydropower, railway and highway sector application widely.Prestress anchorage cable is a kind of structural system bearing pulling force, its one end is fixed on (or in structure) in stable stratum, the other end be reinforced thing and combine closely, form a kind of new structural complexity, its core tension body is high strength wire.
Anchorage cable engineering has become a kind of efficient, economic and practical engineering means in geotechnical engineering.But this structure is under earthquake operating mode, because the strenuous vibration of side slope is out of shape, moment huge pulling force is produced to anchor cable, some positions of anchor cable structure very easily produce stress and concentrate, as the antiskid thread structure of Anchor Cable Anchorage intermediate plate and the steel strand position of clamping thereof, easily cause screw thread stripped thread or steel strand brittle failure when the steel strand of antiskid thread structure and clamping thereof can not bear this stress, cause the inefficacy of whole anchor cable structure, thus make slope instability cause huge harm.
Chinese patent 200910190942.X discloses a kind of quake-proof anchor rope, this anchor cable structure is when instant impact suffered by anchor cable exceedes the maximum static friction force between antidetonation ground tackle and anchor cable, anchor cable produces relative to antidetonation ground tackle and slides, thus the instant impact of buffering earthquake, the absolute growth of free section of anchor cable is elongated simultaneously, the instant impact of further reduction anchor cable, avoids anchoring system to transship or cable body is broken, and reaches the object of antidetonation.
Anchor cable structure disclosed in above-mentioned patent has certain effect to the impact force alleviating earthquake moment.But this structure mainly utilizes the telescopicing performance of free section of anchor cable to reduce the instant impact of anchor cable, and anchor cable self still may be in overload condition; When instant impact suffered by anchor cable exceedes the maximum static friction force between antidetonation ground tackle and anchor cable, anchor cable produces relative to antidetonation ground tackle and slides, and now the antiskid thread of antidetonation ground tackle may produce stripped thread, causes antidetonation ground tackle to lose efficacy.
Simultaneously, in the urban construction of making rapid progress, the temporary supportings such as the underground space, foundation ditch temporary lining, subway, mine, municipal administration, when adopting common anchor cable (bar), cannot reclaim after inefficacy, form underground building rubbish, cause environment pollution, cause significant impact to the exploitation of adjacent plot, cannot reclaim, also in other provisional reinforcing is speedily carried out rescue work, cause the wasting of resources, have impact on urban development, the development and utilization of the underground space.
Patent of the present invention relates to a kind of civil engineering work, and utilize steel wire, reinforcing bar or the steel wire etc. in geotechnical engineering field have the more high-tensile rigid material combination of rigidity, recyclable structure.For various anchorings such as building and reinforcings.In conjunction with all kinds of soil nailing, common bolt, enlarged footing anchor pole, high-pressure rotary-spray anchor pole, anti-floating (pressure) etc., anchor pole uses, and solving conventional anchor cable (bar) cannot reclaim, and forms underground building rubbish, cause environment pollution, to adjacent plot pile foundation construction, municipal administration, the excavation such as subway impacts.
Thus, need to be further improved existing anchor cable structure.
