Description
Technical field
The utility model relates to technical field of building construction, hammer into shape more particularly, to a kind of base expanding and base expanding pile.
Background technique
It needs to handle ground before construction of buildings, to enhance the bearing capacity of ground, to ground pore-forming
When, it will usually use column hammering blow pore-forming, specific operation process are as follows: column hammer, which is increased to certain height again, falls its freely
Under, pore-forming is realized by impact force, finally carries out the perfusion of installation reinforcing bar and concrete.But the load of traditional pile body is mainly by stake
Collateral resistance undertakes, and when stake top bears the load that superstructure transmits, then passes to soil layer by pile body.Pile body have downward displacement or
Displacement trend, the soil body then provide the frictional force for preventing the displacement or being displaced trend, and bored concrete pile can generate sedimentation in the process, lead
Cause the bearing capacity of single pile poor, the withdrawal resistance that can bear is small.
Utility model content
The purpose of this utility model is to provide a kind of base expanding and base expanding pile hammers, can increase the volume at bottom, stake bottom friction
Increase, single pile bearing capacity with higher and withdrawal resistance reduce sedimentation.
To achieve the above object, the utility model the following technical schemes are provided:
