Abstract
The utility model discloses a pile-plate foundation for a self-supporting iron tower, which pertains to construction components. The pile comprises a root pile (3), a bottom plate (2) and basic poles (1). The bottom plate (2) is connected with the root pile (3) into a whole to be buried under the ground. The basic poles (1) of the same number as column feet are arranged above the bottom plate (2). The basic poles (1) extend out of the ground. The vertical and horizontal bearing properties are good under the foundation of the subjacent bed with flabby ooze. The pile-plate foundation is convenient to construct and the production cost is lower, thus being suitable for all soil textures, especially the foundation with a relatively deep supporting layer, a not thick soft soil layer and a shell layer with certain hardness.
Description
Technical field
The utility model relates to a kind of underground building member of surface structures, more particularly is meant a kind of stake slab foundation of the iron tower of supporting oneself.Be particularly suited for as the basis of building power transmission and transformation self-support iron tower on the soft soil layer.
Background technology
What often adopt in the soft soil layer at present is the big plate base or the pile foundation of self-support tower, and for the bearing stratum buried depth is big, thickness of soft soil is little and the ground of certain crust layer is arranged, then has anti-pulling and the relatively poor phenomenon of effect of toppling.As the 500 kilovolt important transmission lines of electricity of Gezhouba Water Control Project to Wuchang, wherein PengPeng Hu-extremely solely Cang Hu is the Plain landforms for about about 130 kilometers, upward is mud matter lam and silt clay alternating layers, based on mud matter lam, between folder thin layer powder fine sand, soft moulding is main, is plastic interlayer secondly, about thick about 15～25m, in be grey fine silt, in close, this layer thickness is about 55～65m, 80m is following to be basement rock.About 50 kilometers to the Wuchang kV Substation of and for example only Cang Hu upward are mud matter and mud matter lam layer, and soft moulding is main, be mingled with some plastic shape thin layers, its thickness is about 15～20m, and the middle level is a fine sand layer, in close, about thick about 60m, be basement rock about the 80m of lower floor.Under above-mentioned geological condition, if big slab foundation or pile type foundation have been adopted in design, will exist occupy cultivated land many, problems such as the prestressing force frequent adjustment of needs of backguy and anti-pulling and the effect of toppling are bad, especially as continue under the situation that snow disaster and storm wind weather increases gradually, its security and stability is faced with great threat.Thereby ground is handled and the pattern selection on basis is the key subjects that weak soil matter area work transmission line presses for solution with design optimization.
Summary of the invention
The purpose of this utility model is defective and the deficiency that overcomes prior art vertical and Its ultimate bearing capacity difference under the weak substratum foundation condition of mud matter, and a slab foundation of the good self-support iron tower of a kind of horizontal force resistant and overturning or slip resistance analysis power is provided.
For realizing above-mentioned technical purpose, the technical scheme of taking of the present utility model is: a kind of stake slab foundation of the iron tower of supporting oneself, comprise the pile that supports column foot, described pile is made up of pile, base plate and pilum, base plate and pile link into an integrated entity and are embedded in below ground, be provided with the pilum that equates with column foot quantity above base plate, pilum elevates above the soil.
The diameter of described pile is 0.3～0.5 meter, and the quantity of pile is more than or equal to the quantity of pilum.
The top of described pile is provided with the back taper boss that is connected with base plate.
Described base plate is square plate or circular slab, and the length of side of base plate or diameter are 1.2～1.5 times of adjacent two pilum spacings, 0.3～0.5 meter of the thickness of base plate.
Described base plate is made up of chassis and structural slab, structural slab be arranged on the outer on chassis and earthward the top turn up, the angle on structural slab and plane, chassis is 20～90 to spend.
Described base plate base plane is 1～2 meter apart from the buried depth on ground.
Described pilum is cubic cylindricality, and its cross dimensions is 0.6 * 0.6～1 * 1 meter, perhaps is cylindrical, and its diameter is 0.6～1 meter.
The center of the axle center of the stone bolt misalignment pilum of connection column foot and close base plate on the described pilum.
By implementing technique scheme, the beneficial effects of the utility model are:
1. owing to adopted the structure of pre-buried base plate and mini pile, combine big plate base and pile foundation advantage separately, basic horizontal force resistant and overturning or slip resistance analysis power have been improved and vertical and horizontal bearing characteristic under the weak substratum foundation condition of mud matter, improved the performance of basis differential settlement under horizontal loads, strengthened the stability of working in the basis on deep mud substratum.Increased the column foot basis lifting surface area.Thereby guaranteed self-support iron tower stability of ground fixedly time the on the weak soil quality layer.
2. used mini pile diameter is less, and pre-buried base plate is provided with acclivitous structural slab, and horizontal bearing capacity is higher, easy construction, manufacturing cost is lower, is applicable to various soil properties area, is particularly suited for that the bearing stratum buried depth is big, thickness of soft soil is little and the ground of certain crust layer is arranged.
