Further, described production method adopts vertical die batch production, and mould comprises external mold (1), core (7), collet (5) and shaping cap (8).
Further, described production method sets up the production room, underground (10) integrating production and steam curing.
Further, core (7) is fixed in production room, underground (10).
Based on the electric pole production method of self-compacting concrete compared with traditional horizontal centrifugal bar method, following beneficial effect should be had:
(1) the present invention relies on dead load forming by self-compacting concrete, removes centrifugal forming operation from, and little to the damage of mould, mould utilization factor is high.
(2) production of high mechanization of the present invention, automation and the good combination property of self-compacting concrete, good product quality, qualification rate are high, without phenomenons such as dew muscle, laitance, running pulps.
(3) each operation of the present invention all can realize continuous productive process mass production, and labour takies less, production efficiency is high.
(4) the present invention reduces construction noise, improves the working environment of workman and the living environment of surrounding resident, realizes Green civilization and produces.
In sum, mould utilization factor of the present invention is high, good product quality, and production efficiency is high, realizes Green civilization and produces.
