Description
Technical field
The invention belongs to forming pile technical field, more particularly, to a kind of stake with welded reinforcement concrete pile tip and its
Construction method.
Background technique
Stake is the vertical or inclined basic component being set in soil, and its role is to pass through weak high-compressibility soil layer
Or water, the load that stake is born are transmitted on harder, the lesser soil supporting layer of more closely knit or compressibility.Pile top is welded on stake
Head, band pile body enter soil layer, as the pile top that first segment head is broken ground, break ground and squeeze into convenient for pile crown.Play the role of having
It prevents infiltration from entering stake inner hole, is also prevented from the inner wall that soil squeezes swollen stake during piling, while also increasing bottom face loading end
Product increases bearing capacity.
In the prior art, steel pile tip is using welding, and high reliablity, hard breaking ground property is good, but at high cost, anti-corrosion effect
Difference, easily infiltration；Concrete pile tip production is simple, cheap, but connects without reinforcing bar, poor mechanical property, and pile top part
Folding is easy in construction to fall.
Summary of the invention
In view of this, the present invention is directed to propose a kind of welded reinforcement concrete pile tip, by the way of welding by pointed cone and
Reinforcing bar combines, and is poured concrete vibrating forming；The advantage of the two is taken into account, high reliablity, breaking ground property is good, and prepares simple.
