Description

A kind of recoverable soil nail bar construction
Technical field
This utility model relates to vibration isolation wall technology field, is specially a kind of recoverable soil nail bar construction.
Background technology
In the reinforcing and support technology of foundation ditch, side slope and underground engineering, Concrete-Nail Bracing Technology Used application is the widest General, plate brad supporting is a kind of new gear soil technology for building foundation pit and stability of slope, due to this technique Economical, reliable and construct quick, easy, the most it is widely used, plate brad supporting takes full advantage of The intensity of foundation soil itself, arranges the method for soil nailing by excavation soil body limit, limit and reaches the purpose of supporting, soil Nail Stress property is different from anchor pole, and anchor pole is typically provided with free segment and anchoring section, by the stable soil of far-end Anchoring section in body provides bigger withdrawal resistance, and soil nailing is not the longest and suffered relative to for anchor pole Pulling force is typically small, and Normal practice is to use total length grouting in hole, and centre arranges a reinforcing bar, injecting cement paste It is bonded to a cylindric entirety to bear tension load with reinforcing bar, now, injecting cement paste and the equal tension of reinforcing bar, When side slope is excavated downwards, the soil body deforms, and makes soil nailing bear withdrawal resistance, thus the reinforcing side slope soil body.
Soil nailing has been widely used at present in the pattern foundation pit supporting structure and side slope consolidation projects of architectural engineering, but, In work progress, substantial amounts of soil nailing is set in the soil body, owing to reinforcing bar and injecting cement paste bond integral, its In reinforcing bar cannot pull out, in soil, become permanent barrier by Preserving time, to day rear perimeter edge engineering Foundation construction leaves bigger hidden danger.So, how after soil nailing completes its use function, in time by soil nailing Can the body of rod be pulled out and is seemed more and more important, the most also become the critical problem that use soil nailing.
China Patent Publication No. CN202108052U discloses a kind of after using in building foundation pit supporting engineering Can complete the soil nailing reclaimed, it is in rock, the soil body after pore-forming, in the cement injection body in hole, utilizes Anchorage node is by tight to steel strand wires or reinforcing bar anchor, thus completes the function of carrying, is provided with insurance in anchorage node It is provided with separation sleeve between device, steel strand wires or reinforcing bar and injecting cement paste, after a protective function completes, insurance can be opened Device, makes steel strand wires or reinforcing bar and anchorage separately, and steel strand wires or reinforcing bar are pulled out the soil body, completes to reclaim, One soil nailing can arrange multiple anchorage node, is positioned at the anchorage node of diverse location by its internal strength Spring can adjust steel strand wires or the deformation of reinforcing bar and stressing conditions, to intermediate node by endpoint node Playing anchorage effect successively, this technical pattern is more complicated, owing to mutually being limited by multiple anchorage nodes Making in-situ test, power transmission is not the clearest and the most definite, it is impossible to soil nailing cement slurry Shi Hanzhang, and the body of rod is returning Time receiving needs to break through the intermediate plate of multiple node, reclaims and has bigger difficulty.
Utility model publication number CN101608450A discloses a kind of removable soil nailing, but it merely illustrates soil Some ingredients of nail wall, soil nailing does not has concrete recyclable structure, and the most broadly explanation is to pull out The soil nailing removed, practical value is little, to this end, we have proposed a kind of recoverable soil nail bar construction.
