Description

内肋增强外波纹型塑料缠绕结构壁管材及其制造方法 Enhanced inner rib wound outer corrugated plastic pipe wall structure and manufacturing method

技术领域 FIELD

[0001] 本发明涉及一种内肋增强外波纹型塑料缠绕结构壁管材及其制造方法,该种管材的外波纹加强筋内含一条和管壁垂直的加强肋。 [0001] The present invention relates to an inner rib reinforced plastic outer corrugated pipe wall winding structure and a manufacturing method, the kind of the corrugated tubing outer bead containing a vertical wall and the reinforcing ribs.

背景技术 Background technique

[0002] 在市政排污管道建设中,为减少污水渗漏,保护地下水源和土壤不受污染,大量地推广使用大口径塑料排水管。 [0002] in the municipal sewage pipeline construction, in order to reduce water leakage and protect groundwater and soil from pollution, promote the use of a large number of large-diameter plastic pipes. 埋地自流式排水管道一般承受内压小,主要需提高抗土壤外挤压力。 Gravity and the buried drain pipe is generally subjected to pressure is small, the outer major need to improve the soil release the pressing force. 这就需要一方面提高管材的环刚度,另一方面通过增加管材与土壤的结合面积、加强回填土的密实度来完善管土共同作用,以提高管材抗压性。 This requires on the one hand to improve the ring stiffness of the pipe, on the other hand by increasing the area of ​​the pipe and soil combine to enhance the density of backfill to improve the pipe-soil interaction, in order to improve the compression of the pipe. 目前市场上的钢带增强聚乙烯(PE)螺旋波纹管、聚乙烯塑钢缠绕排水管、双平壁钢塑排水管、硬聚氯乙烯(PVC-U)钢塑复合缠绕管等都是通过复合钢带的方式增强管材的环刚度。 Currently on the market reinforcing strip polyethylene (PE) spiral bellows, polyethylene wound steel pipes, double flat plates Plastic pipes, PVC (PVC-U) Steel winding pipe and the like through the composite are strip ways to enhance pipe ring stiffness. 但钢塑复合的技术还有待完善,钢材的耐腐蚀性差等问题,使钢塑类复合管在用于输送腐蚀性的污水时仍存在一定的质量安全隐患。 But plastic composite technology should be improved, and poor corrosion resistance of steel, so that steel-plastic composite pipe there are still some quality and safety problems when used in sewage transporting corrosive.

[0003] 大口径纯塑料管目前主要有聚乙烯或硬聚氯乙烯双壁波纹管、硬聚氯乙烯加筋管、增强聚丙烯(FRPP)模压管、聚乙烯缠绕结构壁管材A型、聚乙烯缠绕结构壁管材B型。 [0003] large diameter plastic pipe is mainly pure polyethylene or PVC double-wall bellows, PVC pipe reinforced, reinforced polypropylene (of FRPP) molding pipe, polyethylene pipe wall winding structure type A, poly ethylene-wall pipes type B winding structure. 各种管材管壁的轴向局部剖面结构分别如图1的a、b、c、d和e。 a, b, c, d and e 1 is a partial axial cross-sectional structure of a variety of pipe wall are shown in Figs.

[0004] 双壁波纹管的制造方法是由塑机在熔融状态下连续挤出内外两层同心管,在内外管刚挤出还未冷却时,外管在上下或左右履带式模块的牵引和真空吸附下,形成连续的中空波型加强筋,并将该中空波形的“波谷”部位和内管的外壁在半熔融状态下压接在一起, 冷却后形成管体。 [0004] The method for producing a double-walled corrugated pipe presses by inner and outer concentric tubes continuously extruded in a molten state, when freshly extruded inner and outer tubes has not yet cooled, the outer tube of the crawler traction module in the vertical or horizontal, and under vacuum, to form a continuous wave-type hollow stiffener, and "trough" portion of the outer wall and the inner tube in a semi-molten state together with the crimped hollow waveform, the tubular body is formed after cooling. 该管材外壁中空波形加强筋所形成的管材结构厚度可以达到管材直径的8%,有较高的管壁惯性矩,所以能经济有效地提高管材的环刚度;同时外壁的波纹形也增加了管材外表面积,有利于实现管土共同作用。 The outer wall of the hollow pipe structure pipe thickness waveform reinforcing rib formed can reach 8% of the pipe diameter, the wall has a higher moment of inertia, it is possible to effectively improve the economy of the pipe ring stiffness; while the outer wall of the corrugated pipe increases The external surface area, is conducive to interaction of soil pipe. 但是,如在生产过程中因材料粘接性差或温度控制上的问题没有使内外层有效熔接(见图1. a, 1熔接位),在施工回填后极易在土壤的挤压下造成内外层分层甚而垮塌。 However, as in the production process because of a problem on the poor adhesion material or temperature control is not effective welding the inner and outer layers (see FIG. 1. a, 1 welding position), inside and outside can easily result in the extrusion of the soil after the application backfilling layer delamination even collapse. 同时其制造设备价格昂贵,市场发展空间有限。 While its manufacturing equipment is expensive, limited market development.

[0005] 硬聚氯乙烯加筋管和增强聚丙烯(FRPP)模压管的管壁轴向剖面结构基本相同, 分别如图lb、c,由于没有形成中空的加强筋结构,在环刚度相同时其经济性较同材质的波纹管差。 [0005] PVC pipe reinforced and reinforced polypropylene (of FRPP) molding the tube wall axially substantially the same cross-sectional structure as shown in Figures lb, c, since the hollow rib structure is not formed, in the same ring stiffness its economy is poor compared with the same material bellows.

[0006] 聚乙烯缠绕结构壁管A型的管壁轴向剖面结构如图ld,其制造方法是先由第一挤塑机挤出断面为矩形的管坯,经真空水冷定型后成为矩形管2,然后使该矩形管连续有规律地并排螺旋缠绕在和成型管材直径对应的圆形成型滚筒上,成型滚筒上装有多条受链轮驱动旋转的小滚轴。 [0006] A polyethylene-type winding structure wall of the tube wall structure of FIG axial section LD, which is for the manufacturing method of the first extruder extruded tube of rectangular cross section, after shaping into a rectangular water-cooled vacuum tube 2, and then the regular rectangular tube continuously spirally wound side by side on the forming drum and forming a circular pipe diameter corresponding to how small roller coat forming drum driven in rotation by a sprocket strips. 与此同时,再由第二挤塑机不断向并排螺旋缠绕矩形管的相邻侧面间隙中挤出熔融的塑料熔胶3,相邻的矩形管在侧向压力下,由熔胶相互熔接在一起,并随着旋转小滚轴转动产生轴向力的推动下不断旋出,形成连续中空壁管材。 At the same time, by the second extruder and then continuously helically wound in parallel to adjacent sides of a rectangular tube gap extruded molten plastic melt 3, adjacent rectangular tubes under lateral pressure, the melt fused to each other in together, and the roller is rotated with rotation of the pinion generates an axial force to push the screw out, form a continuous wall of the hollow tube. 该管材管壁的结构厚度决定于第一挤塑机所成型的矩形管的高度,由于矩形管是在冷却后再缠绕的,矩形管高度越大,则缠绕越困难,一般矩形高度只能在成型管材直径的6%左右,管壁惯性矩较同材质和同重量波纹管差,所以在环刚度相同时经济性也较同材质的波纹管差,同时其外壁为平面不利于形成管土共同作用。 The thickness of the pipe wall structure is determined by the height of the rectangular tube formed by the first extruder, since the rectangular tube is then cooled in the wound, the greater the height of the rectangular tube, the more difficult is wound in a generally rectangular height only about 6% of the diameter of the pipe forming, with the wall material and the moment of inertia compared with the difference between the weight of the bellows, the same economy is also worse than the same material in the ring stiffness of the bellows, while the outer wall is flat against the tube forming a common earth effect. 但该种管材结构稳定、设备简单、生产易于控制。 But such pipes structural stability, the device is simple, easy to control production.

[0007] 聚乙烯缠绕结构壁管材B型的管壁轴向剖面结构如图le,其制造设备和制造过程复杂,同时由于其加强筋是由聚丙烯圆管4外复合聚乙烯组成,在熔融状态下熔接在管壁上,造成管材结构壁惯性矩小,所以尤其是大口径管材在达到同等要求的环刚度时,比其他缠绕结构壁管材经济性差。 [0007] polyethylene pipe wall winding structure B-type wall structure is shown in axial section Le, manufacturing equipment and its manufacturing process is complicated, and because of its reinforcing ribs consists of polypropylene polyethylene composite outer tube 4, the molten when the fused state in the tube wall, resulting in a small moment of inertia of the structural wall pipes, especially large-diameter pipe so that the same reach the required ring stiffness, economy is worse than the other winding structure pipe wall.

[0008] 目前市场上有一种螺旋缠绕波纹管的管壁轴向剖面结构如图2. a,其制造方法是先有第一挤塑机挤出熔融条形塑料片材5,然后使该片材连续有规律地并排螺旋缠绕在装有多只主动旋转小滚轴的圆形成型滚筒上,同时由另一挤塑机构挤出相应梯形管状加强筋6,经水冷真空定型。 [0008] There are an axial cross-sectional structure of a wall of the helically wound FIG 2. a bellows on the market, which is the first manufacturing method of the first extruder, extruding the molten plastic sheet strip 5, and then the sheet material regularly continuously spirally wound side by side on a circular cylinder formed with more than just a small active rotating roller, while the other extruded from the respective extrusion means trapezoidal tubular reinforcing ribs 6, the water-cooled vacuum sizing. 以同样螺旋缠绕方式跨压于管壁上各条状塑料片材相邻边缘的搭接缝部位,梯形管状加强筋底面经适当加热,同时由于塑料片材处于半熔融状态。 In the same manner as the voltage across the spirally wound strip in each of the adjacent edges of the plastic sheet on the wall portion of the lap seam, the bottom surface of the trapezoidal tubular rib suitably heated, and because plastic sheet in a semi-molten state. 在梯形方管上的压轮的碾压下,方管和两层相互搭接的条状塑料片材熔合在一起。 In the trapezoidal square tube under pressure rolling wheel, and the two layers overlap each square tube of plastic sheet strips fused together. 该管材外壁波纹形有利于管土共同作用。 The pipe outer wall corrugated pipe-soil interaction in favor. 但由于其加强筋和聚乙烯缠绕结构管材B型类似,也是冷却定型后缠绕,其结构高度不能太大,所以其管壁惯性矩较同材质和同重量的波纹管小,但较聚乙烯缠绕结构管材A型稍好。 But because of its reinforcing ribs and the like polyethylene pipe B-type winding structure, the winding shape is cooled, the height of the structure can not be too large, so the wall material and the moment of inertia compared with the same weight of a small bellows, but more polyethylene wound A pipe-type structure slightly better. 最大的问题在于其加强筋和管壁的粘接很难控制,如条状塑料片温度过低,则粘接差;如温度过高,条型塑料片材则会从成型滚筒上下坠而难以控制成型。 The biggest problem in that it is difficult to control the adhesive bead and the pipe wall, such as a strip of plastic sheet temperature is too low, the adhesion is poor; such as high temperature, plastic sheet bar will fall from the forming drum is difficult control of the molding. 而且即使完成粘接,条形塑料片材的温度一定低于聚乙烯缠绕结构壁管材A型的熔胶,所以加强筋的侧面始终留有隙缝7,造成应力集中,在环境温度交替变化时熔接面会由隙缝逐步开裂,易造成管壁和加强筋分离而垮塌。 And even if the bonding is completed, the temperature of the plastic sheet strip is less than a certain melt polyethylene wall pipes A winding structure type, the side surface of the rib 7 always remains slot, causing stress concentration, when the ambient temperature welding alternating surface will gradually crack from the slot, easily lead to the separation wall and ribs and collapsed.

[0009] 另外一种传统的缠绕波纹管的管壁轴向剖面结构如图2. b,其制造方法类似聚乙烯缠绕结构壁管材A型,不同的是第一挤塑机挤出的是底面两侧各带有一个相互熔接用的适当形状翼片的异型矩形管8经真空冷却定型后,螺旋缠绕在成型滚筒上,再由第二挤塑机不断向并排螺旋缠绕异形矩形管相邻对应的翼片连接部位挤出熔融的塑料熔胶9,经压轮碾轧而熔接在一起。 [0009] Further the wall of a conventional bellows the winding structure shown in axial section 2. b, which is similar to the manufacturing method of polyethylene type winding structure wall pipes A, except that the first extruder is extruded bottom surface both sides of the rectangular shaped flap having a suitable shape are fused together with a tube 8 by vacuum cooling and sizing, helically wound on the forming drum, and then from the second extruder to keep the rectangular tube shaped spiral wound side by side adjacent the corresponding fin connecting portion melt extruding a molten plastic 9, the press roller grinding mill and welded together. 该种管材最大的弱点是熔接位在管材的最薄弱部位(如图2.b,9熔接位),且熔接面小、熔胶量少,从而降低了管材整体抗弯强度。 The kinds of maximum weakness welded pipe located in the weakest portion of the pipe (FIG. 2.b, 9 bits welding), and the weld surface of small, less melt, thereby reducing the overall flexural strength of the pipe.

[0010] 本发明目的是提供一种新结构形式内肋增强外波纹型塑料缠绕结构壁管材。 [0010] The object of the present invention is to enhance the outer rib corrugated plastic pipe inner wall winding structure to provide a new structure. 本发明的另一个目的是提供该结构形式管材的制造方法。 Another object of the present invention is to provide a method for manufacturing a pipe structure.

[0011] 本发明所提出的新结构形式的螺旋波纹型塑料结构壁管材(如图3)是由圆柱面管壁10,和与管外壁成一体的螺旋加强筋11,加强筋11内含一条和管壁垂直的增强内肋12,垂直增强内肋12将加强筋11分成两个并列的内空腔13,内空腔13是由两个相互垂直的边131和132和另外两条边组成直角梯形。 [0011] The proposed new structure of the present invention, the spiral corrugated plastic pipe wall structure (FIG. 3) is a cylindrical surface wall 10, and a helical tube wall integral reinforcing rib 11, the rib 11 containing an and the inner wall of the vertical reinforcing ribs 12, the ribs 12 will enhance the vertical reinforcing rib 11 is divided into two parallel cavity 13, the cavity 13 is formed and the other two sides 132 and two mutually perpendicular edges 131 composition right trapezoid. 螺旋加强筋11的两个内腔13还可以是两个垂直边和一条斜边组成直角三角形如图4. b,也可以是由两条直角边和各种曲线组成的其它不同形状如图4. C。 Two helical rib 13 of the bore 11 may also be two vertical side and a hypotenuse of a right triangle consisting FIG 4. b, may be a different shape from the other two sides at right angles and curves of various compositions in FIG. 4 . C.

[0012] 在螺旋加强筋11的外顶部,增强内肋12的上部还可以增加实心凸起14。 [0012] In the top of the helical reinforcing bead 11 of the outer, upper portion of the reinforcing rib 12 may also be a solid projection 14 increases.

[0013] 制备本发明上述结构形式的内肋增强外波纹型塑料缠绕结构壁管材,可以通过两套相互配合的挤塑机及相应的辅助设备进行。 [0013] Preparation of the present invention, the above-described structure of the inner ribs reinforcing the outer corrugated plastic pipe wall winding structure, may be performed by two cooperating extruder and the corresponding auxiliary equipment. 首先,第一挤塑机构配合相应的模具挤出塑料异型带材(如图4. a,b,c,15),其断面为一个片材连接着两个中空腔体13 (中空腔体靠近塑料异型带材外侧底角适当小于90度,如图4,151),经水冷真空定型,然后使该塑料异型带材连续有规律地并排螺旋缠绕在成型滚筒上,同时由第二挤塑机不断向并排螺旋缠绕的塑料异型带材相邻间隙中挤入熔融的塑料熔胶,再经过设置于成型滚筒外周对应部位处带相应凹槽结构形式的压轮,对相邻塑料异型带材熔接间隙两边相对应的两个凸起管状空腔进行碾压。 First, the first mechanism with the corresponding extrusion die extruded plastic profile strip (shown in FIG 4. a, b, c, 15), which cross section is connected to a sheet 13 (the two hollow cavity near the body cavity shaped plastic strip suitable base angle less than 90 degrees outward, as shown in FIG 4,151), cooled by vacuum forming, and then the plastic profiled strip continuously helically wound regularly side by side on a forming drum, while the second extruder plastisol gap continuously extruded molten plastic profiled strip to the adjacent spiral wound side by side, then after pressing rollers disposed on the periphery of the outer drum corresponding to the molding portions of the belt structure corresponding grooves of adjacent strip-shaped plastic welding clearance on both sides of the corresponding tubular cavity two protrusions for rolling. 由于塑料异型带材的两个凸起的管状空腔具有上窄下宽的结构形式,使具有相适应凹槽结构形式的压轮的碾压力分解成使两个塑料异型带材充分粘合的挤压力,相邻塑料异型带材侧边的两个管状凸起经熔接后形成管外壁的外凸加强筋11,加强筋11内含一条垂直于管壁的增强内肋12和两个空腔13,相邻塑料异型带材的侧边和熔胶粘接成一体, 形成加强筋11的增强内肋12,相邻塑料异型带材侧边的凸起管状空腔形成加强筋11的两个空腔13。 Since the two plastic hollow tubular projections profiled strip having a narrow width of the upper structure, so that the pressure wheel having a grinding pressure groove structure adapted exploded into the two profiled strips of plastic sufficient adhesion pressing force, two adjacent tubular plastic profile strip side convex projection tube wall is formed by the welding bead 11, bead 11 contains a reinforcing vertical ribs in the wall 12 and two cavity 13, adjacent sides and the melt plastic adhesive strip shaped contact integrally formed within the reinforcing rib 11 of the rib 12, adjacent side edges of the plastic profiled strip forming a cavity of the tubular projection 11 of the bead two cavities 13.

[0014] 设置于大成型滚筒外周对应部位的压轮机构根据需要可以是两个或两个以上,可以通过改变压轮上的凹槽结构形式,逐步压紧两个塑料异型带材之间的熔接缝,使熔接缝中的熔胶在第二次受压时未冷却硬化部份挤出至加强筋11的上部,在压轮上对应凹槽的碾压定型下,塑造起加强筋顶部的实心凸起14。 [0014] disposed on the outer periphery of forming drum large pressure wheel mechanism corresponding to parts required may be two or more, by changing the structure in the form of grooves on the puck, and gradually pressed between two profiled plastic strip weld the welded seam of the melt in the second pressure receiving portion is not cooled and solidified extrudate to the upper reinforcing ribs 11, the shape corresponding to the rolling groove in the pressure wheel from the top of the reinforcing rib shape solid projections 14.

[0015] 为保证接缝中未冷却硬化的熔胶在受第二次及以后压轮碾压时,向加强筋的顶部挤出,应保证塑料异型带材缠绕在成型圆筒上时底角(如图4,151)适当小于90度,同时第一个压轮16的凹槽顶部宽度适当大于相邻塑料异型带材的两个凸起管状空腔的底宽,这样开始时熔胶呈尖口向下的契形(如图5. a, 17熔胶契形截面),使第一个压轮16的碾压完成后,塑料异型带材的底部契形熔胶的尖端由于熔胶量少而温度稍底接近硬化,则在第二个压轮161碾压时,压轮的凹槽会使相邻管状空腔的顶部靠紧,使接缝中多余熔胶从未冷却硬化的顶部熔胶口挤出(如图5. b),形成实心凸起14。 When the base angle [0015] To ensure that the seam is not cooled and solidified by the melt during the second and subsequent pressure wheel rolling, extruding the top reinforcing ribs, to ensure that the plastic profiled strip to be wound on a cylindrical molding (FIG. 4,151) suitably less than 90 degrees, while the top of the groove width of the first pinch rollers 16 by a suitable cavity of the tubular projection is greater than the bottom width of two adjacent profiled plastic strip, this melt was started when after the beak downward wedge (FIG. 5. a, 17 melt wedge-shaped cross section), so that a rolling completion of the first press wheel 16, the bottom of the plastic profiled strip wedge tip melt due melt near the bottom and slightly less curing temperature, the pressure at the time of the second rolling wheel 161, the wheel will press the groove against the tops of adjacent tubular cavities, so that the seam excess hardened melt was cooled never the top of the melt is extruded (Figure 5. b), the solid protrusion 14 is formed.

[0016] 本发明的上述结构形式塑料管材与现有各类型结构壁管材比较有以下优势: [0016] The plastic pipe structure according to the present invention with various types of conventional pipe wall structure has the following comparative advantages:
