Description
Technical field
The present invention relates to honeycombed cement tube-making technology fields, more specifically to a kind of honeycombed cement tubulation and its system
Make technique.
Background technique
It with reinforcing bar is material that pipe of cement, which is with cement, a kind of preset pipeline manufactured with the principle of electric pole centrifugal force.
Concrete duct is also known as cement pressure pipe, concrete reinforced pipe, it can be used as urban construction and builds sewer pipe in base, can be with blowdown
Water, the upper hose and farmland motor-pumped well used in flood control draining and some special factories and miness.It is generally divided into: flat mouth armored concrete
Pipe of cement, flexible tongue and groove armored concrete pipe of cement, bell and spigot armored concrete pipe of cement, F fashioned iron bellmouth pipe of cement, flat mouth set
Ring interface pipe of cement, tongue and groove pipe of cement etc..
The technique of production pipe of cement has centrifugation three kinds of tubulation, overhang roll tubulation and core mould vibrating techniques, in the prior art relatively often
What is used is usually core mould vibrating tubulation, since vertical core mould vibrating tube-making process is using inside and outside two whole pipe dies, mould
The rigidity of tool is very good to be unlikely to deform, and a specification only needs one set of die, so molding concrete Guan Yuandu, caliber size mark
Standard, pipe shaft do not heal up seam, and inside pipe wall finish has compared with centrifuging process and overhang roll technique to be obviously improved.In addition, vertical core model
Tube-making process is vibrated after concrete pan feeding, and rotary squeezing is carried out again to concrete in the axial direction, it is significantly more efficient
The intensity and verticality of nozzle are increased, construction and installation are smooth.
Middle-size and small-size cement tube wall in the prior art is typically all solid core, and centre is without hole, after theing cement solidifies
Characteristic, mutual stress is excessive, and the stress pipe of cement between this material can not disperse or eliminate itself, result in
This structure can not bear very strong external force, will appear broken situation in many cases, and waste many water
Mud material results in the increase of cost, can not but promote the intensity of pipe of cement well, wastes many manpower and material resources, and

Step 2: concreting: by intensity be C30 concreting in one and half outer tube dies (4) and interior pipe mold
(10) between, while pouring, starting shock column (12) makes to shake column (12) vibration, finish until pouring；
Step 3: through-hole generates: room temperature stands 1-3 hours, is again turned on vibration column (12), while it is outer from half to shake column (12)
It is extracted between pipe mold (4) and interior pipe mold (10), until vibration column (12) completely disengages the concrete poured in step 2；
Step 4: maintenance demoulding: maintenance process routinely is conserved, and is dismantled one and half outer tube dies (4) when demoulding, will
Extra reinforcing rod (3) is cut, then interior pipe mold (10) are taken out, and completes demoulding, also will be through to honeycombed cement pipe (1) after demoulding
Often watering continues to conserve, and is covered with film, continues maintenance one week or more time, prevents concrete dry and cracked；
Step 5: examining factory: it includes concrete crushing strength, presentation quality, dimensional discrepancy, interior water that product export, which examines project,
Pressure and external pressure are examined, and can be dispatched from the factory after product quality inspection is qualified.
3. a kind of honeycombed cement tubulation according to claim 1, it is characterised in that: the raw material of the concrete include water,
Cement, sand, stone and concrete additive.
4. a kind of honeycombed cement tubulation according to claim 1, it is characterised in that: the cement redundancy of the concrete
It is 1.00,20 millimeters of maximum size of coarse aggregate, Ta Luodu is 35-50 millimeters, sand coarse aggregate ratio 28-30%, ratio of mud 0.36-
0.39。
5. a kind of manufacture craft of honeycombed cement tubulation according to claim 2, it is characterised in that: multiple vibration columns
(12) upside is equipped with lifting mechanism (11), and the lifting mechanism (11) is fixedly connected with vibration column (12).
6. a kind of manufacture craft of honeycombed cement tubulation according to claim 2, it is characterised in that: half outer tube die
(4) outer surface is fixedly connected with multiple equally distributed vertical reinforcing ribs (5) and horizontal stiffener (6), and vertical reinforcing rib
(5) it is interspersed with horizontal stiffener (6).
7. a kind of manufacture craft of honeycombed cement tubulation according to claim 2, it is characterised in that: a pair of half outer tube
The fixed block (7) being mutually matched is fixedly connected on mold (4), digging on the fixed block (7) there are a pair of of blocked hole (8).
8. a kind of manufacture craft of honeycombed cement tubulation according to claim 2, it is characterised in that: half outer tube die
(4) and the material of interior pipe mold (10) is mould steel, the inner sidewall of half outer tube die (4) and interior pipe mold (10) it is outer
Polishing layer is equipped on side wall.
9. a kind of manufacture craft of honeycombed cement tubulation according to claim 2, it is characterised in that: the vibration column (12)
Surface be coated with polytetrafluorethylecoatings coatings, the polytetrafluorethylecoatings coatings with a thickness of 0.5-1.5 millimeters.
