Description
Technical field
The invention belongs to building foundation engineering and base pit engineering, more particularly to a kind of quick pile splicing structure, prefabricated pile and
Method.
Background technology
In foundation ditch process of construction, generally using cast-in-situ bored pile as interim building enclosure, foundation ditch inside subject structure is complete
After, interim fender post does waste treatment, causes material largely to waste, and geological environment is polluted；Drill simultaneously
Bored concrete pile cast in situs, pile-forming speed and pile quality are influenceed by geological environment, plant equipment.Prefabricated pile is used in foundation ditch,
Prefabricated pile is implanted directly into stratum by drawing hole measure, pile-forming speed is fast, and prefabricated pile can be protected effectively with factorial praluction
Demonstrate,prove pile quality.But traffic condition, site condition and lifting factor are limited to, more than more than 20 meters of prefabricated pile can not whole life
Production, need to meet engine request by pile extension at the scene.As foundation pit enclosure stake, pile body is passed during foundation ditch is ended by the soil body
The lateral pressure come, produces shearing and moment of flexure, on the higher stratum of water level also by the pulling capacity on stratum, therefore, pile body in pile body
Attachment means should meet multiple requirements such as bending resistance, shearing resistance, tension simultaneously.
At this stage, method is welded and mechanically connected more than pile extension mode using end plate.For Type of Welding, prefabricated tubular pile should
With more, stake is saved up and down and is welded at seam crossing two and half steel loops of parcel, steel loop lower edges with stake end steel loop, the connection
Form is preferable for transmission vertical pressure, but is limited to steel loop material, thickness and weldquality, and the form is in resist torque, drawing
Poor in terms of pull out force and shearing force, quality is difficult to ensure that；Mechanical connection method is to be entered using pin by the bolt hole of upper and lower section stake
Row anchoring, this form is influenceed greatly by quantity, the quality of bolt, and the form is sheerly in mechanical connection, it is impossible to form whole with pile body
Body, causes joint shearing resistance, anti-bending strength to meet requirement；It is fast that application number 201610112378.X have submitted a kind of prefabricated pile
Sub-buckle, box are attached by fast mechanical connecting device and construction method, this form using pin, but the joint form stress
Transmission is complex, and stress concentration occurs easily at bolt hole position, material local yielding is caused, and the joint construction costs compared with
Height, in addition, the problem of can not being also balanced in the presence of prefabricated pile verticality and connection speed in the prior art, i.e., in order to protect
The perpendicularity of prefabricated pile is demonstrate,proved, connection speed is just restricted, conversely, then perpendicularity can not be guaranteed.
Accordingly, it would be desirable to for connecting two structures for saving prefabricated pile, carrying out new research and design.
The content of the invention
