Description
Technical field
The utility model relates to the non-grouting anchor of a kind of complete reclaiming type and grabs the cable bolting structure, is applicable to foundation ditch and all kinds of ground, open-pit slope and chamber.
Background technology
Deep foundation pit supporting structure pattern at present commonly used has cement-soil gravity supporting and protection structure, soil nailed wall retaining structure, pile-anchor retaining structure, stake support supporting and protection structure and five kinds of supporting and protection structure patterns of diaphragm wall, may only adopt single supporting and protection structure pattern in the engineering, also may adopt two or more supporting and protection structure pattern comprehensively to reduce cost.Also there is corresponding shortcoming in various supporting and protection structure in its advantage of performance.
Cement-soil gravity barricade compressive strength height, but tension and anti-side rigidity are less, the displacement of barricade top is bigger, to surrounding buildings thing, road, and piping facility security presence potential threat; It is subjected to degree of depth restriction bigger, is not suitable for the darker pattern foundation pit supporting structure of the supporting degree of depth.
Soil-nail wall support arranges soil nailing needs the bigger underground space, and soil nailing belongs to flexible support, is easy to generate moderate finite deformation, when foundation pit deformation is had strict demand, should not adopt the plate brad supporting structure, simultaneously soil nature be had relatively high expectations, be not suitable for being used in weak soil and the loosening sand stratum.
The shared working space of pile-anchor retaining is bigger, and setting up of anchor pole requires the place that spacious surrounding enviroment and the good underground space are arranged; Stable soil layer or rock stratum need be arranged so that anchoring body to be set; Use the pile-anchor retaining structure when the too poor or soil pressure of geological conditions is too big, the curved destruction or the destruction of toppling that be subjected to of supporting and protection structure taken place easily.
The dismounting that the inner support of stake support supporting forms necessary strength and inner support all need occupy certain duration, the inner support of arranging in the foundation ditch has reduced working space, increased the difficulty of excavation, muck haulage and underground structure construction, be unfavorable for raising labour efficiency and saving the duration, along with the increase of cutting depth, this adverse effect is more obvious; When the foundation ditch planar dimension is big, not only to increase the length of inner support, the sectional dimension of inner support also increases thereupon, and economy is relatively poor.
Diaphragm wall cost height, construction technical requirement height, spoir and waste mud need to handle, and except increasing engineering cost, as deal with improperly, also can cause new environment pollution.In addition, the construction of continuous concrete wall duration is generally longer.
Emerging enlarged footing anchor cable and recoverable anchor cable have stronger advantage in recent years.The enlarged footing anchor cable can reduce than the anchoring section length of common anchor cable, and anchor cable construction reduces the influence of surrounding building, and safety improves.The place of some original unconditional construction anchor cable also becomes feasible.The quantity in anchor cable hole reduces, to the globality of underground diaphragm wall with prevent from being leaked with benefit.The uplift resistance of enlarged footing anchor cable can improve more than 2～3 times than common anchor cable, and therefore, the radical of anchor cable and whole project can reduce more than 50%, consider the influence of the some other factor in the actual engineering, and engineering quantity and total cost can reduce about 30%.The enlarged footing anchor cable can overcome the shortcoming of common anchor cable effectively, and single uplift resistance is big, and displacement is little, reliability height, good economy performance; Recoverable anchor cable place compliance is strong, when being used for the temporary work reinforcing, after finishing, its function of use can realize the recovery of anchor cable body easily, thereby can not cause engineering to close on the pollution of the underground space and the obstacle of subsequent development, in the urban construction afterwards wide application prospect will be arranged.
But all exist the job practices complexity in the existing deep foundation pit support technology, the construction costs costliness, the recoverable anchor cable also can not be realized reclaiming fully, etc. problem.In application number was 200410027469.0 Chinese patent, the recyclable anchor cable of the civil engineering that the inventor proposes had been realized the partially recycled of anchor cable, but still left a part of cement paste and metal material in the soil body; In application number was 200620130273.9 Chinese patent, the recoverable prestress anchorage cable that the inventor proposes can be realized the recovery of anchor cable, but still leaves cement paste in the soil body, and recovering means need be by the hoist engine main equipment; In application number was 200910116447 Chinese patent, earth-layer internally strutting umbelliform earth anchor head and strutting tool thereof that the inventor proposes need not grouting, but can not reclaim, and can cause the soil body plastic failure when load is excessive simultaneously, and anchored force is subjected to certain restriction.More than three kinds of inventions in existing literature, there is no and promote the use of.
