Description
Technical field
The utility model is related to technical field of building construction, more particularly to a kind of anti-depression Toft foundation structure.
Background technology
Foundation is the important component of building, and foundation is firm, just building above can be made to use more
To be remote, because of some reasons such as foundation and the building own wt of top, pressure generated to natural ground, can be caused
A series of influences for destroying structure stability, such as settlement of foundation, settlement of foundation are inevitable, the sedimentation journey of a ground
Spend a big chunk factor depend on foundation stability and foundation to the pressure pressure size of subsoil.Mesh
Before, it is increasingly deficient with urban resource with the development of economy, it is enterprising in coastal, riverine, waterfront areas subgrade in recent years
Capable geotechnical engineering is increasing, since these grounds include a large amount of water source in water source, soil property, causes these soft
Property ground compressibility is very strong, stability is very poor, result even in building run-off the straight or occur the phenomenon that sinking.
Utility model content
For the above situation, to overcome the defect of the prior art, the purpose of the utility model to be just to provide a kind of anti-depression
The problems such as Toft foundation structure, the effective solution prior art cannot prevent building run-off the straight or depression well.
Its technical solution solved is that the utility model includes multiple waterproof layers, and waterproof layer is positioned opposite two-by-two to form one
A rectangle, waterproof layer inside are surrounded by double cement-soil-stirred pile, multiple cement are equipped on the inside of double cement-soil-stirred pile
Stake, concrete stake is at cross arrangement and forms the cornerwise structure of surrounding on the inside of double cement-soil-stirred pile, is equipped in concrete stake
It is equipped with mattress layer above first dowel, concrete stake and waterproof layer, flexible foundation is equipped with above mattress layer, is equipped in flexible foundation
Bower Anchor muscle.
Compared with prior art, the utility model has the beneficial effects that：Using waterproof layer, it effectively prevent water around the house
Or to weaken the intensity of ground in Groundwater infiltration to ground, cross concrete stake is set and the first dowel reinforces bearing for ground
Ability, this is simple in structure, fixation, and service efficiency is high.
Description of the drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is the sectional view of A-A in the utility model Fig. 1.
Specific implementation mode
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing.
It is provided by Fig. 1 to Fig. 2, the utility model includes multiple waterproof layers 1, and waterproof layer 1 is positioned opposite two-by-two to form one
Rectangle, 1 inside of waterproof layer are surrounded by double cement-soil-stirred pile 2, and multiple cement are equipped in 2 inside of double cement-soil-stirred pile
Stake 3, concrete stake 3 is at cross arrangement and forms the double 2 cornerwise structure of inside surrounding of cement-soil-stirred pile, in concrete stake 3
Equipped with the first dowel 4, concrete stake 3 and 1 top of waterproof layer are equipped with mattress layer 5, and 5 top of mattress layer is equipped with flexible foundation 6, flexible
Bower Anchor muscle 7 is equipped in basis 6.
The waterproof layer 1 one enclosing square of composition sealed around.
The curing agent of the double cement-soil-stirred pile 2 is P32.5 or P42.5 Portland cements, double coagulation
The stake diameter of native mixing pile 2 is 700mm, and stake spacing is 500mm, and row's spacing is 500mm, is respectively engaged 200mm.
First dowel, 4 upper end is stretched out mattress layer 5 and is welded together with Bower Anchor muscle 7.
Sand, coarse sand, graded sand and stone or rubble etc. during the mattress layer 5 uses, the maximum diameter grain of mattress layer 5 is less than
30mm, the thickness of mattress layer 5 are the length that 150mm-300mm and surrounding width are slightly wider than waterproof layer 1.
The surrounding width of the flexible foundation 6 is slightly less than the width of mattress layer 5.
When the utility model is used,
Waterproof layer 1 is placed downwards in 8 surrounding of ground and forms it into a closed rectangle, in 1 inside surrounding of waterproof layer
Place forms double cement-soil-stirred pile 2 using jet mixing machine pore-forming grouting stirring, in the square that double cement-soil-stirred pile 2 is formed
Concrete stake 3 is squeezed at surrounding and centre position on the inside of shape, the first dowel 4 is placed in concrete stake 3, in concrete stake 3 and waterproof layer 1
Flexible foundation 6 is arranged to form mattress layer 5 in sand, coarse sand, graded sand and stone or rubble etc. above mattress layer 5 during upper surface is placed,
Bower Anchor muscle 7 in flexible foundation 6 is welded together with the first dowel 4.
In 8 surrounding digging groove of ground, waterproof layer 1 is placed in the trench, and waterproof layer 1 is made to form a closed rectangle,
It prevents inside the Groundwater infiltration to ground 8 around the rainwater or ground 8 of sleet sky, to reinforce the whole fastness of ground 8,
In 1 inside surrounding of waterproof layer, single cement-soil-stirred pile 2 is formed by the way that the slip casting of jet mixing machine pore-forming is repeatedly secondary, in coagulation
Native mixing pile 2 continues second row of constructing in the same way before not solidifying, guarantee stake spacing is 500mm, and row's spacing is 500mm,
Each occlusion 200mm, and double-row pile spacing is also engaged 200mm, and multiple concrete stakes 3 are arranged in 2 inside of double cement-soil-stirred pile,
Before concrete stake 3 does not solidify, the first dowel 4 is set in concrete stake 3, the first dowel 4 is made to be welded by mattress layer 5 and Bower Anchor muscle 7
It is connected together, increases the basic integral strength of ground 8.Even if impacting house with sudden force in water or depositing the feelings of many water around the house
Under condition, due to the effect of waterproof layer 1 and cement-soil-stirred pile 2 and concrete stake 3 etc., house run-off the straight or depression will not be made.
Using mattress layer 5 in order that reducing the stress concentration of the bottom of foundation.
Flexible foundation 6 is using tension, resistance to compression, bending resistance, the preferable Reinforced Concrete Materials of shearing resistance.
Compared with prior art, the utility model has the beneficial effects that：Using waterproof layer, it effectively prevent water around the house
Or to weaken the intensity of ground in Groundwater infiltration to ground, cross concrete stake is set and the first dowel reinforces bearing for ground
Ability, this is simple in structure, fixation, and service efficiency is high.
