Abstract
The utility model relates to a kind of base arrangement of underground structure, described underground structure is provided with some basement structure posts, each basement structure column bottom is provided with pile foundation, described pile foundation comprises pile foundation and is positioned at the pile cap above pile foundation, it is characterized in that arranging splash guard between the pile cap of described some pile foundations, under splash guard, lay polyphenyl plate bed course.Bottom described pile cap, plain concrete cushion layer is set.The utility model adopts pile foundation in conjunction with the form of structure of splash guard, and it, meeting under the conditions such as stressed, distortion and function, suitably can reduce construction costs relative to traditional design method.
Description
Technical field
The utility model relates to the base arrangement form of the underground structure without superstructure, is specifically related to the form of structure of a kind of pile foundation in conjunction with splash guard, can be applicable to the base arrangement form of underground garage especially.
Background technology
For the underground garage without superstructure, when ground geological conditions is better and groundwater table is higher, base arrangement adopts flat board or beam slab in conjunction with the form of pile foundation usually, causes structural thickness comparatively large, economically relatively poor because base plate bears larger vertical subgrade reaction.
Summary of the invention
The purpose of this utility model is the base arrangement proposing a kind of underground structure, adopts pile foundation in conjunction with the form of structure of splash guard, and it, meeting under the conditions such as stressed, distortion and function, suitably can reduce construction costs relative to traditional design method.
For achieving the above object, the technical solution of the utility model is: a kind of base arrangement of underground structure, described underground structure is provided with some basement structure posts, each basement structure column bottom is provided with pile foundation, described pile foundation comprises pile foundation and is positioned at the pile cap above pile foundation, it is characterized in that arranging splash guard between the pile cap of described some pile foundations, under splash guard, lay elastic deformation bed course.In specific embodiment of the utility model, described elastic deformation bed course is polyphenyl plate bed course.Bottom described pile cap, plain concrete cushion layer is set.Described splash guard adopts armored concrete slab, is disposed with pea gravel concreten layer, separation layer, polyphenyl plate bed course, waterproof roll and plain concrete bed course bottom splash guard.
The utility model considers that ground geological conditions better and the higher feature of groundwater table, adopt piling strtucture form to bear upper load on the one hand, give full play to the good feature of geological conditions, pile foundation can be used as the effect that anti-floating pile plays opposing water buoyancy simultaneously; On the other hand between the pile cap of pile foundation, adopt splash guard resist buoyancy force of underground water, simultaneously for reduction pile foundation when bearing vertical load on the impact of splash guard, under splash guard, lay the polyphenyl plate bed course that relative rigidity is less.Because the thickness of splash guard can calculate according to actual loading situation, and do not limit by detailing requiments, decrease base plate and the quantity such as excavation of foundation pit, backfill in many cases, thus reduce construction costs.
Accompanying drawing explanation
Fig. 1 is the utility model form of structure floor map.
Fig. 2 is the I-I sectional drawing in Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model will be further described.
Figure 1 shows that a kind of base arrangement of underground structure, described underground structure is provided with some basement structure posts 4, pile foundation 1 is provided with bottom each basement structure post 4, the pile cap 5 that described pile foundation 1 comprises pile foundation 6 and is positioned at above pile foundation 6, its load reaches pile foundation 1 by basement structure post, and the pile foundation 6 in pile foundation 1 can resist as anti-floating pile the water buoyancy that high water level produces.Between the pile cap 5 of pile foundation, adopting splash guard to resist buoyancy force of underground water, in order to reduce the impact of pile foundation 1 when bearing load on splash guard 2, below splash guard 2, laying polyphenyl plate bed course 3.In the utility model, splash guard 2 only needs to resist water buoyancy.Because polyphenyl plate bed course rigidity is little yielding, therefore produce distortion when being subject to load, to dissolve the impact of vertical load, thus make splash guard 2 to bear vertical load, only need to bear water buoyancy, therefore the thickness of splash guard 2 can be smaller.Plain concrete cushion layer 7 is not also set in contact position with pile foundation bottom described pile cap 5.Described splash guard 2 adopts armored concrete slab, is disposed with pea gravel concreten layer 8, separation layer 9, polyphenyl plate bed course 3, waterproof roll 10 and plain concrete bed course 11 bottom splash guard.
The utility model is applicable to ground geological conditions better and the higher situation of groundwater table.
