Description
Technical field
The utility model is related to a kind of side slope embankment supporting construction, more particularly to a kind of stake top counterfort wall supporting knot
Structure.
Background technology
In Civil Engineering Construction, side slope embankment is common engineering usually to be needed to ensure the stability of engineering structure
Will in side slope construction supporting structure, in the processing of side slope embankment through frequently with supporting construction mainly have Cantilever Retaining
Structure and counterfort wall structure.
1, overhang mill pilework
In current slope retaining, overhang mill pilework is applied than wide.It is by artificial digging pile or drilling
Bored concrete pile is arranged in a straight line, and is connected by connection beam, the common structure type for resisting soil lateral pressure or side slope thrust.Cantilevered branch
The advantages of fender pile is, stake can bear larger vertical load, while also have the ability for undertaking stronger horizontal loading, structure by
Force mode is clear, and structure Design and Calculation is simple.
It is more than that certain altitude and support pile fixed section Rock And Soil intensity are insufficient in side slope embankment, overhang mill
Stake lateral force resisting is poor, and deformation is difficult to control, and safety is difficult to be guaranteed, to limit its use scope, even if
It uses reluctantly, it is insufficient to will also result in material use, deficiency in economic performance.
2, counterfort wall structure
Counterfort wall is a kind of armored concrete thin wall-type retaining wall, is mainly characterized by simple structure, construction party
Just, wall body section is smaller, and sole mass is light, can preferably play the strength character of material.On counterfort wall heel slab
Soil body gravity can be reasonably resistant to topple and slide, and riser and counterfort bear the moment of flexure and shearing that soil pressure generates jointly, relatively
Cantilever retaining wall stress is good.
Since the structural stability of counterfort wall is ensured by the gravity to banket above wall body and wall heel slab,
And the setting main function of toe of wall plate is to enhance itself stability against overturning and substrate contact stress, therefore, to foundation soil
Body self stability, bearing capacity and resistance to deformation are more demanding, when barricade ground is in slope edges, it is understood that there may be stability of slope
Property, foundation soil body bearing capacity etc. cannot meet situation, safety it cannot be guaranteed that, then application is restricted.
Invention content
In order to overcome the advantage of the disadvantages mentioned above of the prior art, the utility model combination stake and counterfort wall, provide
A kind of simple, practical, the superior new supporting structure of stress performance, i.e. stake top counterfort wall supporting construction, the supporting construction
By shortening cantilever pile length, stake top is set to be reduced to side slope top between the following ranges of original ground 2m, stake is in the supporting and retaining system lower part soil body
Lateral force (sliding force or soil pressure) while, also to help, the sliding of arm-type barricade provides lateral resistance and vertical ground is held
Power is carried, guarantee helps arm-type barricade to stablize.Since pile length is reduced, the arm of force shortens, and torque reduces, and the moment of flexure of stake is also reduced by, from
And achieve the purpose that the lateral resistance of enhancing.Stake top counterfort wall supporting construction and construction method provided by the utility model,
It itself stability against overturning when can enhance slope edges or weaker foundation soil body bearing capacity and bears side slope and bankets to branch
The transverse pressure that protection structure generates, resistance to deformation and sliding.
The utility model is technical solution used by solving its technical problem：A kind of stake top counterfort wall branch is provided
Protection structure, including stake, connection beam, chock and counterfort wall, wherein the stake is embedded in present situation slight slope face hereinafter, described
Connection beam is located at the stake top portion and connects adjacent studs, the chock be located at the connection beam top edge and with the connection beam
Vertical connection, the counterfort wall include the toe of wall plate that bottom level is arranged at the top of the connection beam and rectangle wall heel slab,
Perpendicular to the shingle nail of bottom and the triangle floor of the connection shingle nail and the wall heel slab, the shingle nail is located at institute
It states right at the top of connection beam, the wall heel slab and the floor extend to the backfill side of counterfort wall, the toe of wall
Plate and the chock horizontal connection.
Stake insertion protolith (soil) the body depth and stake top height determine that general stake top height exists according to stable calculation
Present situation below ground 0.5m~2.0m；Counterfort wall height is determined according to specific geology and project situation, generally takes 4m~15m；
Floor is triangular in shape, and thickness and height are calculated according to stress size and determined；Contact beam section size foundation helps arm-type barricade lotus
It carries and determines；Chock plays the role of blocking and helps arm-type barricade horizontal sliding, and wall heel slab, shingle nail, toe of wall plate are respectively according to the soil body
Horizontal and vertical load, which calculates, determines its thickness.
In the utility model, stake, connection beam, chock, counterfort wall use reinforced concrete structure, and concrete grade is not
Less than C30.
The construction method of the utility model：
According to engineering practice, operating condition and stress to stake and counterfort wall structure carry out Force Calculation, really
Determine number of steel bars, structural form, concrete grade and the quantity of stake and buried depth of stake, chock, connection beam and counterfort wall.
According to arrangement and method for construction, construction stake, connection beam, chock and counterfort wall backfill pressure after concrete strength reaches design strength
The soil body after blank wall.
The utility model compared with prior art, has the following advantages and beneficial effect：
(1) the utility model citation form has the advantages that easy, safe efficient, anti-slipping property is good and bearing capacity is good.
(2) being directed to counterfort wall has wall body section smaller, and sole mass is light, gives full play to soil body Gravitative Loads, gear
The strong feature of native ability, but when being used in that part of the foundation bearing capacity is poor or the place on soil-slope top, foundation capability is not
Both it can meet or ground is unstable, influence its application, the utility model organically combines stake and counterfort wall, give full play to
Advantage can enhance vertical foundation bearing capacity using stake and enhance the self stability of slope foundation, be increased using counterfort wall
The strong ability for resisting transversely acting of banketing, by stake and the common stress of barricade, to greatly improve the support capacity of retaining wall.
