Abstract
The invention discloses a kind of enhanced cross stake of slip casting and its application method, the cross stake includes several slip casting steel pipes, the slip casting steel pipe is arranged at the avris of the cross stake, slip casting steel pipe closing ring is enclosed with the outside of some slip casting steel pipes, the cross stake middle part, which is provided with several core reinforcing bars, the slip casting steel pipe closing ring, is marked with concrete.The present invention uses symmetrical star section, and sets slip casting steel pipe in each end, when prospective design is wrong, test pile or during complicated geology, pile body sinking occurs, can improve bearing capacity at any time by grouting and reinforcing ground, and slip casting steel pipe can also serve as reinforcing bar and be used.Meanwhile, any one steel pipe is blocked, and can be supplemented by closing on slip casting steel pipe, not only increase efficiency of construction, and improves the characteristic of soil around pile matter, increases pile body bearing capacity.
Description
Technical field
The present invention relates to a kind of enhanced cross stake of slip casting and its application method.
Background technology
Due to current mostly using the tradition pile foundation such as steel-pipe pile, rectangular concrete pile, circular cutout stake or CFG, often
When Chang Yinwei prospectings are inaccurate, design is slipped up or constructed in soft layer, cause around pile foundation bottom or stake and weak substratum occur,
So as to cause pile foundation deflection after designed elevation or carrying is goed deep into excessive, so that scrapping pile body, then drive piles again, this is not
But wasting human and material resources, material, and leave many construction problems needs solution.To overcome the problem of weak soil piling is difficult,
People start to explore new structure basis, are ensureing that pile body itself is indeformable simultaneously, are improving top bearing capacity, now a kind of note
Enhanced cross stake is starched just to be born.It is simple because making, and can make can also industrialize prefabricated, high capacity, adaptation
Property it is strong and enjoy favor.At present, pile foundation is rested on using the support such as traditional artificial digging pile, prefabricated pile, steel-pipe pile always
The stage of superstructure stress, it is impossible to pile soil horizon is reinforced by itself slip casting, and a kind of slip casting of present invention offer is enhanced
Cross stake and its application method, can both ensure pile foundation stable stress in various soil layers, and prevent excessive deformation, can increase again on
Portion's bearing capacity.
The content of the invention
The technical problem to be solved in the present invention is to overcome the defect of prior art there is provided a kind of enhanced cross stake of slip casting
And its application method, increase the security used.
In order to solve the above-mentioned technical problem, the invention provides following technical scheme：
A kind of enhanced cross stake of slip casting of the present invention and its application method, the cross stake include several slip casting steel pipes,
The slip casting steel pipe is arranged on the outside of the avris of the cross stake, some slip casting steel pipes and is enclosed with slip casting steel pipe envelope
Hoop is closed, the cross stake middle part, which is provided with several core reinforcing bars, the slip casting steel pipe closing ring, is marked with concrete.
Further, the slip casting steel pipe that opposition is set is fixed by steel pipe closing ring.
Further, several described core reinforcing bars are connected and fixed by strengthening stirrup.
Further, the slip casting steel pipe bottom is provided with the pulp mouth of pipe, and the root of the slip casting steel pipe is provided with plug.
Further, by using steel pipe closing ring, across is fixed into the colligation of slip casting steel pipe；By using enhanced hoop
Muscle, can be fixed into symmetrical structure by core arrangement of bar；By using the pulp mouth of pipe and plug, slip casting steel pipe is sealed, it is ensured that suitable
Sharp slip casting；By casting concrete and slip casting, the enhanced cross stake of slip casting is formed.
The beneficial effect that is reached of the present invention is：Using symmetrical star section, and in each end, slip casting steel pipe is set,
When prospective design is wrong, test pile or during complicated geology, there is pile body sinking, grouting and reinforcing ground can be passed through at any time, carrying is improved
Power, and slip casting steel pipe can also serve as reinforcing bar and be used.Meanwhile, any one steel pipe is blocked, and can be able to by closing on slip casting steel pipe
Supplement, not only increases efficiency of construction, and improves the characteristic of soil around pile matter, increases pile body bearing capacity.
