Description
Technical field
The present invention relates to processing unit (plant) and the processing method thereof of a kind of small-bore PCCP pipe (Φ 1000mm is following).
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 following two kinds of conventional methods:
The first, for the above size of Φ 1000mm (containing Φ 1000mm), adopt vertical vibrating technological forming tube core, the folding of internal mold adopts the method that manually enters the manual folding of internal mold;
The second, for the following size of Φ 1000mm (being small-bore PCCP pipe), adopt centrifuging process, because the interior mode diameter below Φ 1000mm is too little, workman cannot enter operation.Meanwhile, adopt centrifuging process moulding tube core to exist large, the useless slurry of power consumption cannot process, pollute large, the rough shortcoming of inwall.Therefore, producing small-bore PCCP pipe, if adopt vertical vibrating technique, needing to realize manually not entering internal mold, thereby complete the action of internal mold folding.As shown in Figure 10,11, in the time of centrifugal forming, motor 101 drives the support roller of centrifuge 103 to rotate, the support roller of centrifuge 103 drives centrifugal pipe die 102 to rotate by friction, concrete is sent into the inside of centrifugal pipe die 102 by artificial or mechanical method, tube core is by the high speed centrifugation power moulding of centrifugal pipe die 102.
In addition, State Intellectual Property Office is CN2853353Y in the notification number of on 01 03rd, 2007 bulletin, name is called the patent of " Vertical vibrating pipe mold ", it cooperatively interacts left-hand door plate by tommy bar with right door-plate together with, make internal mold form a complete closed circle, penetration concrete slurry between internal mold and external mold, and make concrete grout closely knit gradually, after solidifying, concrete gets final product the demoulding.General principle when its actual use as shown in figure 12, is offered an axial tear at internal mold, and the both sides of tear install respectively two door-plates additional.Before cast, utilize between cylinder 104 drive link winding machine two door-plates and fit, make internal mold rounded; After moulding, utilize air cylinder driven linkage to realize two door-plates and mutually move, make internal mold inwardly shrink and be convenient to the demoulding.But the problem that this structure exists is: one, can only be for more than large scale pipe internal mold 301a(Φ 1000mm, containing Φ 1000mm), reason is that cylinder and linkage are tangential setting, need to take certain space, undersized if (being less than Φ 1000mm), as the outline line of internal mold in figure 301, be difficult to lay; Two, this scheme need to arrange multiple air cylinder connecting rod assemblies at differing heights, and well-known be to be different at the pressure of the concrete slurry of differing heights internal mold outside.If adopt same cylinder assembly, the sealing effectiveness of top and bottom there will be great difference; If adopt the cylinder assembly of draught head in order to overcome the different pressures in differing heights door-plate gap, cannot realize technically.Meanwhile, this technical scheme of utilizing cylinder needs to keep the pressure of long period after cast in concrete setting process, and the energy consumption while making to use is very big, and cost is high.
