Description
Technical field
The present invention relates to anchoring support field, particularly relate to a kind of combination that is used to geotechnical anchor engineering that temporary supporting is providedMember and utilize its construction method.
Background technology
In City Excavation Engineering temporary supporting, anchor rod construction process is widely used, steel strand wires etc., and hardware often surmounts and buildsBuild red line, in the underground netted radiation of contiguous zone, after main structure construction completes, the steel member of residual inefficacy can be to proximityTerritory exerts an influence, and arranges pipeline to construction in later period, and underground space development causes difficulty.
Along with the enhancing of underground space property right protection consciousness in city development, in anchor bolt construction, surmount the phenomenon of building red line by strictRestriction. 20th century the eighties, American-European countries's recoverable anchor rod construction technology progressively start application, through more than 30 years send outExhibition, the land development region of anchorage engineering construction limits relevant laws and regulations gradual perfection, carries out related measure and progressively strengthens. At home,Wuhan, Kunming, the application of common bolt has strictly been limited in the areas such as Jiangsu, formulated " soil bolt can not surmount red line,Steel strand wires must reclaim " etc. relevant regulations, ensure not allow adjacent ground property rights are invaded from law angle.
Successively researched and developed multiple recoverable anchor bolt construction technology both at home and abroad, general introduction can be divided three classes substantially, and the one, mechanical type can returnReceive prestress anchorage cable, mainly adopt mechanical device structure to reclaim, represent that there is the SAMWOO of Korea S etc. in enterprise, it uses hookupAnchor cable body and special-shaped deformed bar equijoin are got up, in the time reclaiming, apply with the power of fastening opposite direction and rotate, make anchor cableBody and hookup throw off after by its taking-up; The 2nd, the recoverable prestressed anchor cable of mechanics formula, represents that there are Japanese KTB etc., state in enterpriseInterior Metallurgical Research Institute, Department of Architecture is introduced the U-shaped anchor of exploitation etc., is with having the steel strand wires of outer tube as anchor cable body, is reclaimingTime, steel strand wires are applied to stretching force, it is extracted out by root in anchor cable body; The 3rd, the recoverable prestressed anchor cable of chemical formula, representativeThere is UBC etc. in enterprise, is electro-heat equipment is first installed in stretch-draw body of rod free segment bottom or demolition set is installed, and in the time reclaiming, usesPoint apparatus is processed key point respectively, makes the adhesive section body of rod lose efficacy and extract. Numerous scientific research institutions and enterprise are to recyclable anchorA large amount of research and development that pole technology carries out, have created good economical, societal benefits. Current recoverable anchor pole technology is notWith some shortcomings of existence of degree, financial cost is high, complex process, the shortcoming such as the rate of recovery is low, and single anchor bearing capacity is little.
