Background technology
Construction of buildings on soft foundation at first needs to solve the settlement issues (bulk deposition and different sedimentations) on basis.And on soft foundation construction of buildings, generally adopt pile foundation, deep layer improvement basis, perhaps the composite foundation form that combines with raft foundation of stake.When adopting the support stake, because pile body has run through soft layer, be placed on the supporting layer of ground, and pile body is the perfect rigidity body with respect to soft layer, the peripheral soil in basis changes and during sedimentation in natural conditions etc., building will and ground between because distortion is inconsistent and segment occurred difference phenomenon causes obstacle on the functional performance of building.Thereby for keeping the functional performance of building, in recent years at home and abroad, raft foundation successively occurred to combine with foundation improvement, raft foundation combines with friction pile, composite foundation forms such as deep foundation improvement.In the very dark situation of weak soil layer, since the restriction of execution conditions, difficult stake or the deep foundation improvement worker method supported that be suitable for.And during low layer under construction (in light-duty) building, use and support stake, raft foundation combines with friction pile, during ground forms such as deep foundation improvement, with respect to upper building, tends to become the relatively poor basic worker's method of economic effect.The artificial economy that improves basic worker's method such as applicant, and the different sedimentations on control basis have proposed the basic worker method of raft foundation with following spill foundation improvement.But this worker's method is the shallow layer foundation improvement, and the supporting capacity of vertical direction is comparatively limited.
Summary of the invention
The purpose of this utility model is to provide a kind of raft plate to reach the composite foundation that outer enclosure wall formula foundation improvement combines with cylindricality, adopt the peripheral foundation improvement form of deepening of wall formula in ground edge, to improve the horizontal resistivity of ground, the relative rising of the structure that prevent effectively because the consolidation settlement of peripheral foundation soil etc. caused, thus the long-term functional performance of building kept.
The utility model is achieved through the following technical solutions:
The composite foundation that a kind of raft plate combines with cylindricality and outer enclosure wall formula foundation improvement, this basis have adopted at depth direction and have been the cylindricality foundation improvement of trapezoidal profile and the composite foundation that basic periphery adopts shallow-layer wall formula foundation improvement shape.
The composite foundation that above-mentioned a kind of raft plate combines with cylindricality and outer enclosure wall formula foundation improvement, described composite foundation are that when foundation soil changed, the column of distribution triangular in shape improved.
The composite foundation that above-mentioned a kind of raft plate combines with cylindricality and outer enclosure wall formula foundation improvement, described composite foundation is that when foundation soil changed, the ground periphery was local shallow-layer wall formula foundation improvement.
Advantage of the present utility model and effect are:
1. the utility model is carried out base integral large tracts of land trapezoidal profile column foundation improvement.
2. when the utility model reduces the settling amount of whole building,, the different settling amounts on basis can be reduced, thereby the destruction of the superstructure that causes by different sedimentations can be effectively avoided by regulating the column improvement degree of depth of diverse location.
3. the utility model has relatively large viscosity and certain compressibilty simultaneously because the conditioned soil rigidity will descend to some extent than the rigidity of pile body, can effectively absorb seismic wave energy, exempts to shake effect thereby reach.
