Abstract
The utility model provides a building pile foundation structure on a soft soil foundation. The structure comprises pile bodies and a bearing platform which are connected in a jacking mode; the bearing platform is sequentially provided with a base layer, a reinforced concrete raft board, a filling layer and a seepage layer from top to bottom; drainage ducts are arranged on the seepage layer at certain intervals; a permeable layer is paved between the reinforced concrete raft board and the filling layer; the permeable layer can effectively ensure the reinforcing effect of a shallow soil layer and really forms a hard shell layer with engineering value, so that the bearing capacity of the pile bodies on the bearing platform is fully exerted, and an effect of stress dispersion is achieved; in the presence of the seepage layer and the drainage ducts, water is timely drained in the construction process, the solidification process of soft soil is quickened, and the aims of improving the early solidification strength and the bearing capacity of a surface sludge foundation and reducing later settlement are fulfilled; and the structure is simple and convenient to construct, has the advantages of stability, safety and economical cost, and is widely applied in building construction.
Description
Technical field
The utility model relates to the foundation treatment technology field in the civil engineering work, refers to especially a kind of building pile structure on soft foundation.
Background technology
As everyone knows, no matter be skyscraper, or brick and tile one-storey house, any building whether firm all be unable to do without construction early stage to the processing of ground, in case improper to treatment of Foundation Construction, the situations such as building collapsing, casualties then occur easily, bring and seriously influence for people's production, life.So the soundness of ground is directly determining the steadiness of building.
China's area is vast, and soft foundation is not within minority, especially is seen everywhere especially in the riverine and coastal area, has brought sizable difficulty for various engineering constructions.And mainly be to adopt cushion or surcharge preloading method for the processing method of soft foundation at present.
But obversion can only be applicable to the Soft Ground of shallow-layer, processes thickness and is no more than 2m; The duration that the surcharge preloading method needs is very long, be not suitable for very much for the engineering that construction period is arranged, and the expenditure cost of these two kinds of methods is higher, is unfavorable for reducing the cost of construction enterprises.
Therefore, be with widely soft soil layer at China's riverine and coastal one, need economical rationality, construct soft-soil foundation treatment method fast or structure are technical barriers of the vast construction enterprises of restriction.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy construction in order to overcome the existing defective of above-mentioned background technology exactly, has firm safety, the more economical novel soft foundation structure of cost.
For achieving the above object, the technical solution adopted in the utility model is: a kind of novel soft foundation structure, consisted of by pile body, cushion cap, described pile body and cushion cap hold and join, this cushion cap is provided with basal layer, Reinforced Concrete Raft plate, packed layer and seepage floor from top to bottom successively, be provided with the drainage pipe of arranging at a certain distance on the seepage floor, between Reinforced Concrete Raft plate and packed layer, also be equipped with pervious layer; Drainage pipe is located at the side of pile body, and the soft foundation layer is goed deep in the lower end of drainage pipe.
Further step is: the spacing of drainage pipe is 5～15m; The thickness of Reinforced Concrete Raft plate is no less than 30cm; Pervious layer is equipped with rubble or rough sand in its structure, the thickness of its pervious layer is no less than 15cm; Packed layer is equipped with sandstone in its structure, the thickness of its packed layer is no less than 30cm; Seepage floor is the aspect of the mesh shape made by timber or geo-grid or reinforcement bar, and the thickness of its seepage floor is no less than 10cm.
Compared with prior art, the utility model is reasonable in design, simple in structure, favorable working performance, in the cushion cap each layer structure can be processed separately, can guarantee compactness, the pervious layer that arranges between Reinforced Concrete Raft plate and packed layer, can effectively guarantee the consolidation effect of superficial part soil layer, real form the crust layer with construction value, so that pile body can be not fully exerted to the bearing capacity of cushion cap, play the effect of stress diffusion.
Shorten the duration of a project and reduce construction costs, for programming provides reliable guarantee, seepage floor and drainage pipe have a timely discharge that is beneficial to moisture in the work progress, accelerated the process of soft soil consolidation, to reach the purpose that improves early stage consolidation strength, top layer muck foundation bearing capacity and reduce posterior settlement.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present utility model.
Among the figure, 1, basal layer, 2, the Reinforced Concrete Raft plate, 3, pervious layer, 4, packed layer, 5, seepage floor, 6, drainage pipe, 7, pile body, 8, soft foundation.
The specific embodiment
In conjunction with shown in Figure 1, the utility model comprises the cushion cap that is laid on soft foundation 8 surfaces, and deep pile body 7 two parts to soft foundation 8 inside, wherein cushion cap is provided with basal layer 1, Reinforced Concrete Raft plate 2, packed layer 4 and seepage floor 5 from top to bottom successively, between Reinforced Concrete Raft plate 2 and packed layer 4, also be equipped with pervious layer 3, drainage pipe 6 is evenly arranged in the side of pile body 7 with the spacing of 5m, the upper end of drainage pipe 6 and seepage floor 5 connect, the lower end of drainage pipe 6 is beneficial in time discharge moisture deeply to soft foundation 8.
During construction, according to the situation of soft foundation 8, determine the quantity of pile body 7 and the area of cushion cap.At first squeeze into pile body 7 toward the inside of soft foundation 8, lay the seepage floor 5 of the mesh shape of being made by reinforcement bar on the surface of pile body 7 again, the thickness of its seepage floor 5 is 10cm at least, lays simultaneously the drainage pipe 6 suitable with pile body 7 quantity; Secondly on the surface of seepage floor 5 from the bottom to top successively laying depth be the packed layer 4 of 30cm, thickness is the pervious layer 3 of 15cm, and thickness is the Reinforced Concrete Raft plate 2 of 30cm; Situation according to building is laid basal layer 1 above Reinforced Concrete Raft plate 2 at last, to guarantee the steadiness of building on the cushion cap.
