Technical field
The present invention relates to a kind of foundation pile, particularly relate to a kind of concrete-pile being used in architectural engineering and Structural Engineering
And Combined concrete stake.
Background technology
When building large-scale or high-rise, if meeting with that formation strength is not enough or during soft soil horizon, application is often needed to put
Enter underground foundation pile and the load-carrying of the building on upper strata is transferred to the domain of soil bearing bed or harder, to increase building
The safety of thing structure and stability.Wherein, modal pile-type formula in again with prestressed concrete pipe pile as Engineering Market.
Refering to Fig. 1,2, existing prestressed concrete pipe pile 1 includes one with made by concrete and in define one
The concrete pile lining in hole 111 11, two lays respectively at 11 liang of end opposite of this concrete pile lining and can be connected with this endoporus 111
Ring-type end plate 12, several two ends are embedded in described ring-type end plate 12 and respectively along the abnormity of this concrete pile lining 11 longitudinal extension
Rod iron 13, and one along this concrete pile lining 11 Y-direction total length and the spiral steel wire 14 outside being wound around described profiled bar 13.
On practice is applied, the winding spacing of this spiral steel wire 14 in the two ends head section of this prestressed concrete pipe pile 1 is
Less, it is typically spacing 5 to 10 centimetres (cm), and is bigger at the interlude of this prestressed concrete pipe pile 1, typically
About at spacing 10 to 30 centimetres (cm), this is to cooperate with structure design, to strengthen this prestressed concrete pipe pile 1 close to termination
The intensity at position, and cost can be taken into account.Described profiled bar 13 generally has applying first pull-type prestressing force, mixed to increase this prestressing force
The intensity of solidifying soil pile tube 1 and durability.
Put on the active force on the stake top of this prestressed concrete pipe pile 1, be transferred to this end plate 12 or described different on stake top
Shape rod iron 13, then it is transferred to the lower section of this prestressed concrete pipe pile 1.And this spiral steel wire 14 is except being used for bearing this concrete
Outside horizontal shear suffered by pile lining 11, also it is provided that the lateral support of described profiled bar 13.
Existing prestressed concrete pipe pile mostly 1 is to make the most in the factory, then with vehicle load to construction at, for fear of system
Making the length limitation of mould and carriage of vehicle, therefore, the length of existing prestressed concrete pipe pile 1 is mostly at 8 to 18 meters (m)
Between.If the degree of depth length more than a prestressed concrete pipe pile 1 of this prestressed concrete pipe pile 1 underground need to be inserted
Time, just must engage several prestressed concrete pipe piles 1, to reach required soil depth demand.
Refering to Fig. 3, the relatively conventional joint of existing prestressed concrete pipe pile 1 be utilize welding manner seam two upper,
The end plate 12 of lower stacked prestressed concrete pipe pile 1, to be combined into longer stake, extends prestressed concrete pipe pile 1
Entire length.It is stacked the combination between two prestressed concrete pipe piles 1 up and down, is to rely on two prestressed concrete pipe pile 1 joints
End plate 12 seam combine, rely on other mechanical bolts engage or plug engage mode reach.Due to these two in advance should
Combination between power concrete tubular pile 1 is the mode generally implemented on current civil engineering worksite, and not special in the present invention
Profit application range, is seldom described herein at this.
It is equally known that the structural strength of this weld 100 is the most fragile, and this weld 100 Prolonged exposure in
In the environment of underground or subsoil water, and described end plate 12 is all steel part, be susceptible to corrosion and affect bond strength with
