Abstract
The invention relates to a foundation structure comprising foundation walls, concrete piles, a flyash-lime pile, backing layers and a concrete raft. The foundation walls are walls with trapezoidal sections, cross sectional area of the bottom of each foundation wall is larger than that of the top of the same, the concrete piles and the flyash-lime pile are arranged between the two foundation walls, the depth of the foundation walls is larger than that of the concrete piles and the flyash-lime pile, the backing layers are arranged at the top ends of the foundation walls, the concrete piles and the flyash-lime pile, and the concrete raft are arranged above the backing layers. The foundation structure is hollowed in the middle, force borne on the upper portion is uniformly scattered to the lower layer of the concrete, and the structure is more stable and firm through the hollowed design. By arranging the foundation walls, the concrete piles and the flyash-lime pile, and sinking of the soft soil layer and tilting of the foundation can be effectively prevented. Meanwhile, deep concrete piles are used partly, and manufacturing cost is low.
Description
Technical field
The invention belongs to the realm of building construction, particularly relate to a kind of Toft foundation structure.
Background technology
At present, the building of building on the soft foundation such as lakeside, river marsh by the sea,, depression or rhegma much can occur to tilt, as very high in whole use deep pile foundation costs, and adopt raft foundation that common strip foundation is single etc. can cause that a large amount of sinkings even tilt, cause very large economic loss.Common Toft foundation structure adopts the solidifying soil layer of very thick meeting as ground, needs a large amount of concrete, has caused certain waste.
Summary of the invention
The present invention provides a kind of simple in structure, easy to install, Toft foundation structure of increasing work efficiency for solving the technical problem existing in known technology.
The technical scheme that the present invention takes for the technical problem existing in solution known technology is: this Toft foundation structure comprises: ground body of wall, concrete pile, the stake of two ash, bed course, concrete raft plate; Described ground body of wall is that cross section is trapezoidal body of wall, the bottom transverse sectional area of ground body of wall is greater than top cross-sectional area, between two ground bodies of wall, mix and be provided with concrete pile and two ash stake, the degree of depth of the depth ratio concrete pile of ground body of wall and two ash stakes wants dark, top in ground body of wall and concrete pile and two ash stakes is provided with bed course, is provided with concrete raft plate above bed course.
The present invention can also adopt following technical measures:
Described concrete pile is arranged on the diagonal of two ground bodies of wall, and two ash stakes are arranged on other regions between two ground bodies of wall.
The cross section of described concrete pile is circular, and the top of concrete pile and the cross-sectional area of bottom are greater than the cross-sectional area of middle part.
Described two ash stakes are made up of quicklime, flyash and coarse sand.
Described bed course is formed by rubble, gravel and cement compacting.
A kind of Toft foundation structure also comprises: concrete pile, concrete lower floor, concrete hollow out frame, concrete upper strata; Described concrete pile is arranged on underground, and concrete pile upper end is connected with concrete lower floor, and described concrete hollow out frame is arranged in the middle of concrete lower floor and concrete upper strata, and is connected with concrete lower floor and concrete upper strata with bar construction.
Advantage and good effect that the present invention has are: the Toft foundation structure in the present invention adopts three layer concrete layers, the design of middle employing hollow out, the power that upper part can not only be born is distributed to Hui Ningtu lower floor uniformly, and hollow out project organization is more stable, firmer, in ensuring the quality of products, reduce again concrete use amount.By ground body of wall is set, layout concrete pile and two ash stake, can effectively prevent that Soft Soil Layer from sinking and ground tilts, and avoided the dark stake of whole use concrete simultaneously, and cost is lower.

Detailed description of the invention
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Embodiment 1:
Fig. 1 is the schematic diagram of a kind of Toft foundation structure provided by the invention, and this Toft foundation structure comprises: ground body of wall 1, concrete pile 2, two ash stake 3, bed course 4, concrete raft plate 5; Described ground body of wall 1 for cross section be trapezoidal body of wall, the bottom transverse sectional area of ground body of wall 1 is greater than top cross-sectional area, between two ground bodies of wall 1, mix and be provided with concrete pile 2 and two ash stake 3, the degree of depth of the depth ratio concrete pile 2 of ground body of wall 1 and two ash stakes 3 wants dark, top in ground body of wall 1 and concrete pile 2 and two ash stakes 3 is provided with bed course 4, is provided with concrete raft plate 5 above bed course 4.
Described concrete pile 2 is arranged on the diagonal of two ground bodies of wall 1, two ash stake 3 other regions that are arranged between two ground bodies of wall 1.
The cross section of described concrete pile 2 is circular, and the top of concrete pile 2 and the cross-sectional area of bottom are greater than the cross-sectional area of middle part.
Described two ash stakes 3 are made up of quicklime, flyash and coarse sand.
Described bed course 4 is formed by rubble, gravel and cement compacting.
A kind of Toft foundation structure also comprises: concrete pile 2, concrete lower floor 6, concrete hollow out frame 7, concrete upper strata 8; Described concrete pile 2 is arranged on underground, and concrete pile 2 upper ends are connected with concrete lower floor 6, and described concrete hollow out frame 7 is arranged in the middle of concrete lower floor 6 and concrete upper strata 8, and is connected with concrete lower floor 6 and concrete upper strata 8 with bar construction.
Advantage and good effect that the present invention has are: the Toft foundation structure in the present invention adopts three layer concrete layers, the design of middle employing hollow out, the power that upper part can not only be born is distributed to Hui Ningtu lower floor uniformly, and hollow out project organization is more stable, firmer, in ensuring the quality of products, reduce again concrete use amount.By ground body of wall is set, layout concrete pile and two ash stake, can effectively prevent that Soft Soil Layer from sinking and ground tilts, and avoided the dark stake of whole use concrete simultaneously, and cost is lower.
