Description
Technical field
The present invention relates to engineering construction technology fields, and in particular to prefabricated pile and its construction party is inscribed in a kind of mortise and tenon type
Method.
Background technique
Prefabricated pile can make in factory, and building-site carries out piling, and short time limit may be implemented to produce in batches, and reduction is applied
Work cost.Since the prefabricated pile length of plant produced is generally 10~12 meters, when engineering geological condition difference needs long stake
When, it needs to carry out pile extension in building-site.Currently used pile extension technology has welded connecting to connect with ring flange, both pile extensions
Method is needed in the connection pre-buried steel ring of pile crown.And have the following disadvantages a little: 1, when using being welded to connect, in order to avoid weldering
Connection pile crown dislocation caused by deformation is connect, two workers is needed symmetrically to weld, it is more demanding to the technical level of worker, it needs
Higher labour cost is wanted, while connecting steel ring under welding residual stress effect, is easily corroded.2, when being connected using ring flange,
It will cause connection pile crown section and be greater than pile body section to increase piling difficulty, and ring flange also easily corrodes in soil.
Summary of the invention
