Description
Technical field
The present invention relates to processing unit (plant) and the processing method thereof of a kind of small-bore PCCP pipe (below Φ 1000mm).
Background technology
Prestressed concrete cylinder pipe (Prestressed Concrete Cylinder Pipe) is called for short PCCP, is a kind of novel rigidity tubing.
At present, domestic making PCCP tube core has a following two conventional method:
First, for Φ 1000mm dimensions above (containing Φ 1000mm), use vertical vibrating technological forming tube core, the folding of interior mould uses
The method being manually entered the manual folding of interior mould；
Second, for the following size of Φ 1000mm (the most small-bore PCCP pipe), use centrifuging process, because below Φ 1000mm's is interior
Mode diameter is the least, and workman cannot be introduced into operation.Meanwhile, use centrifuging process molding tube core exist big, the useless slurry of power consumption cannot process, pollute big,
The rough shortcoming of inwall.Therefore, producing small-bore PCCP pipe, according to vertical vibrating technique, needing to realize not being manually entered
Interior mould, thus complete the action of interior mould folding.Such as Figure 10, shown in 11, when centrifugal forming, motor 101 drives the torr of centrifuge 103
Wheel rotates, and the support roller of centrifuge 103 drives centrifugal pipe die 102 to rotate by friction, concrete by method manually or mechanically send into from
The inside of heart pipe die 102, the tube core high speed centrifugation power molding by centrifugal pipe die 102.
Additionally, State Intellectual Property Office is CN2853353Y in the notification number of on 01 03rd, 2007 bulletin, entitled " vertical vibrating
Pipe die " patent, it makes interior mould form a complete closed circle together with being cooperated with right door-plate by left-hand door plate by tommy bar, including
Penetration concrete slurry between mould and external mold, and make concrete grout the most closely knit, after concrete curing, get final product the demoulding.Base when it is actually used
Present principles as shown in figure 12, offers an axial tear at interior mould, and the both sides of tear install two door-plates respectively additional.Before cast, utilize cylinder 104
Drive link mechanism realizes fitting between two door-plates so that interior mould is rounded；After molding, air cylinder driven linkage is utilized to realize two door-plate phases
Motion mutually so that interior mould is easy to the demoulding to contract.But this structure there is the problem that one, can only be for mould 301a in large scale pipe
(more than Φ 1000mm, containing Φ 1000mm), reason is cylinder and linkage is tangential setting, needs to take certain space, if
Undersized (less than Φ 1000mm), such as the contour line of mould 301 in figure, then is difficult to lay；Two, the program needs to set at differing heights
Put multiple air cylinder connecting rod assembly, and it is well known that in differing heights the pressure of concrete slurry outside mould be different.If used
The sealing effectiveness of same cylinder assembly then top and bottom there will be great difference；If for the difference overcoming differing heights door-plate gap
Pressure and use the cylinder assembly of draught head cannot realize the most technically.Meanwhile, this technical scheme utilizing cylinder, after being cast
Need to keep the pressure of long period during concrete setting so that energy consumption during use is very big, and cost is high.
Summary of the invention
