Description

A scarfing cinder fat liquoring curing means for tubular pile mould

Technical Field

The invention relates to the field of die application, in particular to a slag-removing, oil-coating and maintenance device for a tubular pile die.

Background

The pipe piles are classified into post-tensioned prestressed pipe piles, pre-tensioned prestressed pipe piles, prestressed concrete pipe piles (PC pipe piles), prestressed concrete thin-wall pipe piles (PTC pipe piles) and high-strength prestressed concrete pipe piles (PHC pipe piles). The pre-tensioning prestressed pipe pile is a hollow cylindrical elongated concrete prefabricated member made up by adopting pre-tensioning prestressed process and centrifugal forming method, mainly formed from cylindrical pile body, end plate and steel ferrule. The tubular pile is divided into a prestressed concrete tubular pile, a prestressed high-strength concrete tubular pile with the code of PC, a prestressed high-strength concrete tubular pile with the code of PHC, a thin-wall tubular pile with the code of PTC, wherein the concrete strength of the pile is not lower than that of C50 concrete, the strength of the thin-wall tubular pile is not lower than that of C60, and the strength of the PHC pile is not lower than that of C80. The PC piles and the PTC piles are generally maintained by normal pressure steam, and can be driven after 28 days. And the PHC pile is subjected to autoclave steam curing after demoulding, and the concrete strength grade reaches C80 and only needs three or four days from forming to using after the steam curing is carried out at about 180 ℃ under 10 atmospheric pressure.

The pretensioned prestressing pipe pile is a hollow cylinder body elongated concrete prefabricated component which is manufactured by adopting a pretensioned prestressing process and a centrifugal forming method, a pipe pile mould is needed in the centrifugal process, the pipe pile mould is one of main equipment in the pipe pile production process, the use frequency is high, and the working condition is severe. The mould produces the deformation easily, and running wheel wearing and tearing are very fast, damage the back, just can't reach the required rotation rate of centrifugal forming, seriously influences the tubular pile quality, and normal use is generally just restoreed 2 ~ 3 years. Some tubular pile enterprises can only simply repair damaged moulds and continue to use the moulds with diseases. The professional factory repair not only has long period, but also has high repair cost, and the repair method is not reasonable. Therefore, how to reduce the repair cost and prolong the service life of the die is a very concerned problem in the pipe pile industry. The pipe pile die can be used for removing slag and maintaining in time, so that the service life of the die can be prolonged, and therefore, a slag-removing and oil-coating maintenance device for the pipe pile die is urgently needed to be developed for removing slag and maintaining the pipe pile die.
