Description
Technical field
The present invention relates to building pile foundation engineering construction technical field, more particularly to a kind of stake and stake attachment structure and its construction
Method.
Background technology
Pile foundation can bear larger uplift load due to high capacity, and field, embankment work are built so as to be widely used in room
Journey, retaining wall structure and transmission line foundation etc..Precast reinforced concrete pile can in factory's mass production, pile quality
Lean on, be the larger pile foundation material of current usage amount.
In prefabricated pile basis work progress, the connection of stake and stake is an important construction technology, and it resists to foundation pile
It is larger to pull out performance impact.Connection between stake and stake at present uses and is welded to connect or enters along pile body transverse direction built-in bolt sleeve mostly
Row connection.When being welded to connect, because staff's level difference causes pile body quality of connection to differ greatly, construction technology quality is not
Easy to control, pile crown welding quality is difficult to carry out mechanics detection.In addition, during Site Welding, uncertain factor is more, difficulty of construction
Larger, welding interval is grown, and labor strength is big, and welding quality is difficult to control.Connected along pile body transverse direction built-in bolt sleeve
When connecing, the bolt shearing resistance under uplift load effect, required Number of Bolts is more.Bolt collar is typically welded on pile crown end plate, its
The more difficult accurate control in position, therefore stake side connecting plate upper bolt hole is usually slotted hole, so that bolt is connected with bolt collar.Should
Under less uplift load, two may disengage for connection method, produce the amount of pulling out on certain, until on screw rod and connecting plate
Uplift effect is just played when bolt hole is in close contact.
