Abstract
A novel prestressed spiral anchor tube relates to the technical field of prestressed spiral anchor tubes. The novel prestressed spiral anchor tube comprises an anchoring anchor tube section, a free anchor tube section, an anchor plate, a prestress lock nut and a spiral anchor tube section. The free anchor tube section is arranged between the anchoring anchor tube section and the spiral anchor tube section and is fixed with the spiral anchor tube section via the anchor plate and the prestress lock nut. The free anchor tube section is an unthreaded anchor tube. A PE (poly ethylene) plastic sleeve tube is arranged on an outer wall of a joint between the free anchor tube section and the anchoring anchor tube section, an antiseptic butter layer is coated between the free anchor tube section and the PE plastic sleeve tube, and a grout stop valve is arranged at the top of the PE plastic sleeve tube. The novel prestressed spiral anchor tube is manufactured by simple process, low in manufacturing cost and suitable for temporary and permanent supports for various slopes. Besides, construction cost can be saved, and working benefit and safety can be effectively improved.
Description
Technical field
The utility model relates to prestressed anchor Manifold technology field, is specifically related to a kind of high-pressure slip-casting prestressed spiral anchor tube that pattern foundation pit supporting structure, road slope, building slope are used that is used for.
Background technology
Along with the high speed development that Chinese Urbanization is built, the traffic of aboveground space becomes more and more serious problem, so just makes human traffic have to develop to the underground space.Therefore the reinforcing of underground construction just becomes the right matter of utmost importance of demand side.The prestressing force anchor tube is as an important method of geotechnical engineering reinforcing in modern age; In China's developing history of existing decades; At present, people apply to the prestressing force anchor tube in tunnel and the underground construction, and the prestressing force anchor tube can improve the non-deformability of underground construction.
Present anchor tube kind on the market is more, but also there is certain defective in it: 1, self tapping precession anchor tube: parameters cooperates appropriate, and the rig torque demand is big, and the unit anchored force is little under the individual cases; 2, spin grouting anchor pile: the grouting process holding time, construction environment is poor, limited speed system; 3, spin resin anchor tube: the anchor pole installation needs specific drilling tool; 4, bore the precession anchor tube certainly: construction needs specific drilling tool; 5, spin whitewashing anchor tube: can not be used for rock crushing band loose media.Therefore, there is certain restriction in existing anchor tube when using, and applicable surface is little.
Summary of the invention
The purpose of the utility model provides a kind of novel prestressed spiral anchor tube, and its job practices is easy, and cost is low, can effectively improve working efficiency and safety, is applicable to the interim and permanent support of all kinds of side slopes.
In order to solve the existing problem of background technology; The utility model is to adopt following technical scheme: it comprises anchoring section anchor tube, free section anchor tube, form anchor, prestressing force lock nut and thread segment anchor tube; Be provided with free section anchor tube between anchoring section anchor tube and the thread segment anchor tube, and free section anchor tube is fixed through form anchor, prestressing force lock nut and thread segment anchor tube.
Described anchoring section anchor tube is for there being spiral anchor tube (market has finished product), and its outer wall evenly is provided with triangle and revolves silk.
A described free section anchor tube is an irrotationality silk anchor tube, and its junction outer wall with the anchoring section anchor tube is provided with the PE plastic bushing, and is coated with anticorrosion butter layer between free section anchor tube and the PE plastic bushing, and the end of PE plastic bushing is provided with grouting stop-valve.
The utility model as the basis, is provided with free section and anchoring section with common spiral anchor tube.The free section of anchor tube coating butter is made outer again PE sleeving plastic pipe after the preservative treatment, is provided with form anchor at thread segment, locks through nut with torque wrench during stress tension.This is a kind of novel prestressed spiral anchor tube, and this prestressed anchor pipe has recuperability.The utility model job practices is easy, and cost is low, can effectively improve working efficiency and safety, is applicable to the interim and permanent support of all kinds of side slopes.
