The invention provides a kind of novel core tubulation apparatus: comprise bottom tray, external mold and roll dish, described bottom tray comprises tray body, in described tray body, there is through hole, the upper surface of described tray body has for the fixing parts of socket steel ring, on described parts, have a plurality ofly around the uniform screwed hole in the center of described through hole, in described screwed hole, there is the screw through described screwed hole by described parts outside;
Described external mold comprises outer mould body, the upper surface of described outer mould body has for the fixing bellmouth steel ring retainer ring of bellmouth steel ring, described bellmouth steel ring retainer ring and described outer mould body coaxial line, on described bellmouth steel ring retainer ring, have around the uniform a plurality of screwed holes of described external mold body axis, in the described screwed hole on described bellmouth steel ring retainer ring, be rotary with screw;
On the sidewall of described outer mould body, lean on its position, upper surface around the uniform a plurality of screwed holes of described external mold body axis, described screwed hole described in each on external mold body sidewall all has the threaded rod matching with it, described threaded rod mould body outer wall from described stretches out through described screwed hole inwall of mould body from described, and its extension can be held bellmouth steel ring;
The described working face that rolls dish is plane.
Further, the specific practice that screwed hole is set on the sidewall of mould body is outside: pre-buried a plurality of nuts on the sidewall of described outer mould body, the screwed hole by its position, upper surface on the sidewall of described outer mould body is the screwed hole in described nut.
Further, describedly for the fixing parts of socket steel ring, comprise a plurality of socket steel ring fixed heads, described socket steel ring fixed head is uniform around the center of described through hole, described in each, the plate face of socket steel ring fixed head is all over against the center of described through hole, and described screwed hole is positioned on described socket steel ring fixed head plate face.
The present invention also provides a kind of core pipe-making method that adopts the said equipment, comprises the steps:
, socket steel ring is positioned in the through hole of bottom tray, be fixed;
(2), the inside and outside framework of steel reinforcement assembling is placed on bottom tray, fix, outer die casing, on framework of steel reinforcement, is fixed on bottom tray;
(3), threaded rod is tightened, bellmouth steel ring is positioned in the part of stretching out external mold madial wall of threaded rod, tightens the screw on bellmouth steel ring retainer ring, with this, bellmouth steel ring is fixed;
, (1) step is enclosed within fixedly to internal mold to the mould assembling in (3) on, with the short muscle of connection, framework of steel reinforcement and socket steel ring and bellmouth steel ring are welded and then carry out concreting;
, built after concrete, first with the vibration moulding that runs up of core main shaft, then roll socket plan with rolling dish, hang out pipe die.
Because the application adopts socket, be inverted tubulation, socket is the effect of being stressed in bottom, and maximum at bottom core plug exciting force, so concrete is the most closely knit; And socket size is by the size Control of socket steel ring, and spigot is shaped on collet, can not produce any distortion; Bellmouth size is due to the common configuration control of bellmouth steel ring, jackscrew and threaded rod.Therefore the present invention has advantage and good effect are: owing to adopting technique scheme, the concrete steel pipe socket concrete compaction of producing, socket size is accurate, not yielding, while rectifying a deviation in jacking construction cushion rubber keep away water-based can be good.
