With the infringement of urban operating mechanism, bad border is also protected, there is good social benefit.
External supporting structure and construction method in a kind of building foundation pit provided by the invention, take hole in ball-type turning support and
Upperpush rod, down-pressed pole connect with support pile, reach and support pile supported retaining is acted on, reduce or avoid high inclination-angle anchor pole/rope
Level pulls the phenomenon reduced, and reduces pressure at right angle of the high inclination-angle anchor pole/rope to support pile, effective protection device.
External supporting structure and construction method in a kind of building foundation pit provided by the invention, anchor pole/rope are directly embedded into rock mass,
The anti-pulling capacity of anchor pole/rope can be not only increased substantially, and soil bolt and weathering mudstone layer creep can be avoided
The adverse effect of amount.Due to the raising of anti-pulling capacity, so that it may reduce anchor pole dosage, save raw material and reduce construction costs.
External supporting structure and construction method in a kind of building foundation pit provided by the invention, by the pull-type retaining structure of anchor and support
Formula retaining structure is combined, and forms combined retaining structure system, suitable for relatively deep big base pit engineering.Not only increase earth-retaining knot
The elastic support of structure, anchor pole axial tension and inner support axial compressive force value are improved, base pit engineering quality and base is also effectively ensured
Cheat the security used.
