Background technology
Along with the high speed development of urban construction, the buildings such as a large amount of high-rise buildings, underground garage, sunk type square and subway, underground store have proposed higher level requirement to the utilization of the underground space.Yet, underground soil layer moisture enrich soil layer property be large thickness weak soil coastal cities as Shenzhen, Dalian and Qingdao etc., the superstructure run-off the straights such as the building being caused by Groundwater buoyancy, structure, the accident of collapsing occur repeatedly, basement anti-floating problem is seemed and become increasingly conspicuous.
Pile-raft foundation is the combination of pile foundation and raft foundation, it has the feature of pile foundation and raft foundation concurrently, there is the advantages such as integral rigidity is large, bearing capacity is high, non-deformability is strong, anti-seismic performance is good, and can effectively adjust and avoid structure generation uneven subsidence, be widely used in high level or super highrise building, the ground that also can be used for harbour, airport, large-scale logistics stockyard is processed project.In the higher area of groundwater table, along with the increase of the basement degree of depth, the anti-floating of pile foundation and raft plate is had higher requirement.
Anti-float anchor rod is the anti-floating technology of existing modal application quantity maximum, and large-scale stake raft structure also usually solves anti-floating problem by anti-float anchor rod is set.Traditional anti-float anchor rod operating principle is to adopt high-pressure slip-casting technique to make slurry infiltration among the hole of Rock And Soil, utilizes the frictional resistance of the interaction generation of anchor pole and the finished soil body of slip casting to carry out balance buoyancy.The feature of anti-float anchor rod has: the more general anti-floating pile of side friction of (1) anchor pole is larger, and larger stretching resistance can be provided; (2) anchor pole arranges than comparatively dense, even so the bending and shearing of the required balance of sole plate also reduces thereupon and one or two anchor pole lost efficacy still can guarantee integrally-built anti-floating performance; (3) anti-float anchor rod can play the effect of certain consolidated subsoil, but more limited to the contribution of load.Due to above-described anti-float anchor rod, Gu compare with other anti-float methods, there is the equipment of anchor bolt construction simple, technique is clear and definite, and speed of application is fast, Gu it has larger advantage aspect functional performance, construction, cost and duration.
Although traditional anti-float anchor rod has above various advantages, but also exist its deficiency and shortcoming: first the anchoring effect of the longer anchor pole of length of anchor pole is just better, but in deep soft clay area in order to obtain good anchoring effect, the length of anchor pole certainly will will increase, and this has obviously increased difficulty of construction and cost; Secondly longer anchor pole will inevitably strengthen difficulty and the quality of slip casting, affects anchoring effect; Then traditional anchor pole is to adopt first pore-forming and then bury anchor pole underground, can cause the problems such as collapse hole, particularly for the area that has deep soft soil, can affect the anchoring effect of anchor pole; Last anchor pole is very limited to the contribution of basic vertical bearing capacity, other structures generally need to be set and bear vertical bearing capacity.
