技术领域
本发明涉及增强热塑复合结构壁管技术领域，特别涉及一种增强热塑复合结构壁管管材、带材及其成套 生产装置。
背景技术
水资源的保护是保护生态环境的重要组成部分。 目前，造成地下水污染的主要原因是城市或工业排污管 道的渗漏， 为此传统的铸铁管、 钢筋混凝土管已逐渐或正在被各种类型的埋地用塑料结构壁管材所替代。
塑料结构壁管有两种主要工艺： 直接挤出成型和様绕成型。缠绕成型的塑料结构壁管是由塑料中空带材 或塑料异型带材连续缠绕而成，这种工艺既适用于较大口径，也适用于全尺寸规格系列的塑料结构壁管的制 造。
推广这种塑料结构壁缠绕管的最大难点在于不能保证補设施工的质量。 由于种种条件的限制， 并不是所 有的工程都能够保证管道周围的回填材料达到规定的压实程度， 比如铺设场地的土壤条件较差、承受的负栽 较重， 或者虽然能够达到但是工程费用太高， 例如需要从外地购买和运进全部回填材料， 在这种情况下采用 较高环刚度的管道常常是必须的或者是更经济的。
全塑料結构壁管由于材料弹性模量比较低， 需要耗用较多的材料才能达到要求的环刚度。 例如： 内径 2000mm ， 环刚度 SN8 的全塑料缠绕结构壁管米重达到 499公斤。 无论 ¾料结构壁管有多少优点， 如果 价格太高， 用户也 4 接受。

从上述的技术方案可以看出， 本发明提供的增强热塑复合结构壁管具有如下突出优点：
一是可以提髙管材环刚度，以增强型材为钢带，热塑材料以聚乙烯为例，钢的弹性模量是聚乙烯的 200 倍以上（碳素钢的弹性模量在 190000 Mpa左右， 聚乙烯的弹性模量在 800Mpa左右） , 在大弹性模量钢 材的作用下， 增强热塑复合结构壁管可轻易达到 SN16 ( kN/m2 )或以上的环刚度， 弥补了较大直径全塑料 结构壁管一般环刚度较难达到 SN8 或以上的弱点。 因此在各种使用条件下的工程中都可以采用。 例如在某 些沿海地区，由于土壤中含腐蚀性物盾，如果使用混凝土管工作寿命会很短，但是当地的土壤承载能力很差， 地下水位又高， 过去因为没者高环刚度的塑料结构壁管产品无法满足设计要求， 现在就可以采用增强热塑复 合结构壁管。
二是原材料的消耗量显著较少， 上迷增强热塑复合结构壁管最重要最突出的优点就是在达到高性能的 同时， 非常显著地节约原材料。 众所周知， 一项技术创新能够降低材料消耗 10%通常就认为是重要成果。 增强热塑复合结构壁管和全塑缠绕结构壁管相比在同样直径同样环刚度下材料米重将减少近一半，成本的降 低将更多。 原因就在钢的弹性模量比聚乙烯大 200倍， 钢塑复合加强结构达到的环刚度远超过多层厚实的 聚乙烯结构 产生的效果。 适当设计增强型材复合加强结构的厚度和高度就可以轻易地达到要求的环刚度。 以环刚度 SN8 为例， 在全系列规格尺寸中增强热塑复合结构壁管和全塑缠绕结构壁管的米重比在 0.35-0.61 。 值得注意的是在增强热塑复合结构壁管的米重内大约近一半是聚乙烯的重量， 另一半是钢材的 重量。 钢材的价格大约是聚乙烯价格的一半。 以内径 2000mm , 环刚度 SN8 为例， 全塑料缠绕结构壁管 米童高达到 499公斤，增强热塑复合结构壁管总的米重为 170公斤，折合材料成本降低至全塑管的 25% , 消耗的聚乙烯为 85 公斤仅为全塑管的 17% 。在全系列规格尺寸中增强热塑复合结构壁管的材料成本不到 全塑缠绕结构壁管的三分之一， 消耗的聚乙烯材料不到全塑管的五分之一，在塑料原材料价格爆涨的经济形 势下是非常有价值的应对措施。
增强热塑复合结构壁管既保留了塑料管材具有优良的水力特性， 极强的内外防腐能力及适度的轴向柔 韧性等优点， 又以大弹性模量增强材料优化支撑结构， 可使管材以较低的材料成本， 具备抵抗土壤载荷的足 够环刚度， 因此具有卓越的综合性能。

下面将结合本发明实施例中的附图， 对本发明实施例中的技术方案进行清楚、 完整地描述， 显然， 所描 述的实施例仅仅是本发明一部分实施例， 而不是全部的实施例。基于本发明中的实施例， 本领域普通技术人 员在没有做出创造性劳动前提下所获得的所有其他实施例， 都属于本发明保护的范围。
请参阅图 1-图 4, 图 1为本发明实施例提供的一种增强热塑复合结构壁管带材的结构示意图； 图 2为图 1中 B的局部放大图； 图 3为本发明实施例提供的另一种增强热塑复合结构壁管带材的结构示意图； 图 4为 本发明实施例提供的又一种增强热塑复合结构壁管帝材的结构示意图。
本发明实施例提供的一种增强热塑复合结构壁管带材包括基板 111和与基板 111成一体的加强肋 112, 加强肋 112优选为多条。在加强肋 112内或在基板 11 1和加强肋 112内同时复合有增强型材 113 ,基板 111、 加强肋 112和增强型材 113均沿带材长度方向延伸设置。 其中， 增强型材 113与加强肋 112, 或同时与基板 111和加强肋 112的热塑材料层挤出复合为一体， 且被热塑材料层完全包覆， 增强型材 113为弹性模量大于 热塑材料层的弹性模量的型材。 上述增强型材 113可为至少一个， 或多个条形型材组成。
增强热塑复合结构壁管带材的加强肋 112可由基板 111一侧向同一方向直立并沿带材的长度方向延伸， 基板的另一侧为连续表面 1103 (续绕成管材后， 该侧表面为管材的内壁） ， 并沿带材的长度方向延伸。 多 奈与加强肋 112挤出复合为一体的增强型材总体成间隔排列的 "I"形、 "L"形、 "Γ"形、 "T" 形、 "丄" 形、 "工" 型或其他沿所述直立方向增强的树形截面结构。
在增强热塑复合结构壁管带材内复合弹性模量大于热塑材料层的增强型材 113 , 能够显著提高管材的环 刚度， 并且可以使原材料的消耗量昱著较少。 在大弹性模量增强型材 113的作用下， 由该增强热塑复合结构 壁管带材缠绕成的增强热塑复合结枸壁管可轻易达到 SN16 ( kN/m2 )或以上的环刚度， 弥补了较大直径全 塑料结构壁管一般环刚度较难达到 SN8或以上的弱点， 因此在各种使用条件下的工程中都可以采用。 由该 增强热塑复合结构壁管带材缠绕成的增强热塑复合结构壁管最重要最突出的优点就是在达到高性能的同时， 非常显著地节约原材料。增强热塑复合结构壁管和全塑缠绕结构壁管相比在同样直径同样环刚度下材料米重 将減少近一半， 成本的降低将更多。
如图 3所示，本发明实施例提供的另一种增强热塑复合结构壁管带材的结构示意图，该示意图并非优选 的典型带材结构， 而是用于表示本发明提供的带材结构的各个技术特征。
在多条加强肋 112中，沿带材宽度方向两侧的一个加强肋的外侧面设置了可沿带材宽度方向挤靠的凸块 114构成的横向受力面。 该凸块 1 14构成的橫向受力面用于在带材缠绕成管材时， 与缠绕机上外径成型辊轮 开始端设置的挡块或台阶挤靠，并在多个上述挡块或台阶的螺旋导向下， 使带材卷绕一周时向前旋进一个带 材宽度， 同时也使已卷绕成型的管材螺旋旋进一个带材宽度。 上述加强肋 112之间或顶端还可设置连接筋 ( 115、 116 ) ,用于上述带材和管材螺旋旋进时，增强加强肋 112对横向受力的承载能力；并可在管材制造、 运输、 施工和使用过程， 对管材内壁提供保护， 防止管材内壁因意外受损造成泄漏。 设置在加强肋 112顶端 的连接筋 116还可使螺旋卷绕成型的管材同时具有平整的内壁和外壁， 以便于管道之间的连接。
增强型材 113可包括支撑板 1131 ,或支撑板 1131、第一增强板 1132和 /或第二增强板 1133，支撑板 1131 与第一增强板 1132和 /或第二增强板 1133光滑过渡连接 。
其中， 支撑板 1131位于加强肋 112内， 或同时位于基板 111和加强肋 112内， 并与加强肋 112， 或同 时与基板 111和加强肋 112的热塑材料层挤出复合为一体，且被所述热塑材料层完全包覆。 其作用是提高管 材的环刚度的同时使塑料的消耗量显著减少。
第一增强板 1132位于基板 11 1 内， 并与基板 1 1 1的热塑材料层挤出复合为一体， 且 板 111的热塑 材料层完全包覆。 其作用是保持支撑板 1131的结构稳定和增强带材缠绕成管材时， 加强肋 112对横向受力 的承栽能力， 防止因加强肋的歪斜或倒伏造成管材的环刚度下降。
优选第一增强板 1132的宽度超出支撑板 1131 为 2~5mm， 第一增强板 1132埋入基板 111 的深度为 1/2-1/3处。
第二增强板 1133可设置于支撑板 1131的任一側端部， 并与加强肋 112，或同时与加强肋 112和 /或连接 筋 115、 116的热塑材料层挤出复合为一体， 且被所述热塑材料层完全包覆。 其作用一是以较少的材料成本 提高管材的环刚度， 二是保持支撑板 1131的结构稳定和增强带材缠绕成管材时， 加强肋 112对横向受力的 承载能力。调整第二增强板 1133超出支撑板 1131的宽度和形状,还可在不改变带材外形尺寸规格的条件下， 调整、 改变管材的环刚度。
上述多个加强肋 112的支撑板 1131与第一增强板 1 132和 /或第二增强板 1133 ,可成组或通过连接筋（ 115、 116 ) 总体构成梯形、 波 ί文或其他有利于带材制成管材后， 承受径向压力载荷的组合截面结构。
上述多个加强肋 112的各个增强型材 113的第一增强板 1132和 /或第二增强板 1133从支撑板 1131的外 伸方向可 同或相反。
增强型材 1 13的支撑板 1131 可以至少两个为一组集束设置， 每组加强肋 112的至少两个增强型材 113 的支撑板 1131与第一增强板 1132和 /或第二增强板 ] 133从支撑板 1131外伸的指向可相背排列成 "L" 形、 "Γ" 形、 "Τ" 型、 "丄" 形、 "工" 型或总体排列成其他沿从所述基板外伸的直立方向增强的树形截面 结构。 加强肋 112顶端相背排列的第二增强板 1133之间的凹陷处可被所述加强肋的包覆塑料层填充为平面， 以增加结构的稳定性和外壁的防护， 并可用于带材的上、 下面压紧， 以利于带材的稳定牵引和输送。
上述集束设置的两个支撑板 1 131之间可从一端光滑连接成一体、 或通过结合层连接为一体， 或分别被 挤出成一体的塑料分隔。
增强型材 1 13的最小外覆塑胶层大于 0.8mm。
上述增强型材 113的树形截面结枸具有如下作用：
一是可采用同一套生产装置兼容不同环刚度的管材生产。全塑缠绕结构壁管采用多层厚实的聚乙烯结构 层产生较高的环刚度， 对不同环刚度的管材， 带材的结构层高度差异很大， 造成其成套生产装置的结构变化 较大， 不能通用。 本发明釆用弹性模量远大于塑料的增强材料和树形截面的增强结构， 可在带材结构高度基 本不变的条件下， 以材料成本的最小化为 3标， 通过优化增强型材的树形截面结构来调整管材的环刚度， 以 满足不同土壤条件和回填土变形模量的条件下的管材环刚度要求。因此可采用同一套生产装置兼容不同环刚 度的管材生产。
二是兼容持大管径与通用管径的管材生产。对于采用单一结构模式的增强热塑复合结构壁管， 特大管径 管材的增强型材的结构变化较大， 造成其成套生产装置的结构变化较大， 不能通用。 本发明采用弹性模量远 大于塑料的增强材料和树形截面的增强结构， 可在带材结构尺寸和增强型材的结构尺寸基本不变的条件下， 通过改变增强型材的树形截面结构和增强型材的数量，并以材料成本的最小化为目标进行带材结构的优化设 计， 兼容特大管径与通用管径的管材生产。
三是可对全尺寸规格系列的管材进行结构最优化设计。本发明采用弹性模量远大于塑料的增强材料和树 形截面的增强结构，可以材料成本的最小化为目标，在带材结构尺寸和增强型材的结构尺寸基本不变的条件 下 ,对全尺寸规格系列和不同管材环刚度要求的管材进行优化设计， 实现全尺寸规格系列和不同管材环刚度 要求的管村结构最优化和成本最小化， 以及成套生产装置的总体最优化设计。
将现有的塑料直肋缠绕管、塑料波纹4绕管、 塑料双平壁缠绕管等单一结构设计模式的产品合并为统一 标准、 工艺和设备生产， 可使产品在较高的技术水平上起步， 促进塑料结构壁管材产品的系列化和产品品种 的合理发展， 并将有助于迅速提高塑料结构壁管材的生产技术水平。

增强型材 1 13可包括条形型材的的支撑件 1 134和增强件 1 135。

增强型材 1 13可优选为增强金属带， 增强金属带的弹性模量较大， 环刚度较好。 增强金属带可为钢带、 铝带等适用的金属材料。组成基板 1 1 1和加强肋 1 12的热塑材料 J:为聚乙烯层、 聚氯乙烯层或聚丙烯层等塑 料层。
在其他实施例中， 将上述带材的中空腔结构制成实心结构， 或将上述带材的包覆塑料层改为使用喷塑、 涂敷等适用工艺的塑料层亦在本发明的保护范围之内。 本发明提供的增强热塑复合结构壁管管材，其为由如上实施例公开的增强热塑复合结构壁管带材螺旋缠 绕成型的增强热塑复合结构壁管管材。螺旋缠绕成增强热塑复合结构壁管管材的增强热塑复合结构壁管带材 之间的相邻边之间设置相同或相容材质的挤出塑料焊条或粘合剂层。螺旋缠绕成增强热塑复合结构壁管管材 的增强热塑复合结构壁管带材之间的相邻边表面设置挤出焊条或粘合剂层，且相邻边成相互搭接或榫合搭接 结构。 增强热塑复合结构壁管管材具有光滑平整的内壁和有间距螺旋环绕的增强热塑复合加强结构的外壁。

本发明提供的增强热塑复合结构壁管具有如下突出优点：
一是可以提高管材环刚度，以增强型材为钢带，热塑材料以聚乙烯为例，钢的弹性模量是聚乙烯的 200 倍以上（碳素钢的弹性模量在 190000 Mpa左右， 聚乙烯的弹性模量在 800Mpa左右） ， 在大弹性模量钢 材的作用下， 增强热塑复合结构壁管可轻易达到 SN16 ( kN/m2 )或以上的环刚度， 弥补了较大直径全塑料 结构壁管一般环刚度较难达到 SN8 或以上的弱点。 因此在各种使用条件下的工程中都可以采用。 例如在某 些沿海地区，由于土壤中含腐蚀性物质，如果使用混凝土管工作寿命会很短 ,但是当地的土壤承载能力很差 , 地下水位又高， 过去因为没有高环刚度的塑料结构壁管产品无法满足设计要求， 现在就可以采用增强热塑复 合结构壁管。
二是原材料的消耗量显著较少， 上述增强热塑复合结构壁管最重要最突出的优点就是在达到高性能的 同时， 非常显著地节约原材料。 众所周知， 一项技术创新能够降低材料消耗 10%通常就认为是重要成果。 增强热塑复合结构壁管和全塑缠绕结构壁管相比在同样直径同样环刚度下材料米重将减少近一半，成本的降 低将更多。 原因就在钢的弹性模量比聚乙烯大 200倍， 钢塑复合加强结构达到的环刚度远超过多 J:厚实的 聚乙烯结构层产生的效果。 适当设计增强型材复合加强结构的厚度和高度就可以轻易地达到要求的环刚度。 以环刚度 SN8 为例，在全系列规格尺寸中增强热塑复合结构壁管和全塑缠绕结构壁管的米重比在 0.35-0.61。 值得注意的是在增强热塑复合结构壁管的米重内大约近一半是聚乙； ^的重量， 另一半是钢材的重量。钢材的 价格大约是聚乙烯价格的一半。 以内径 2000mm， 环刚度 SN8为例， 全塑料缠绕结构壁管米重高达到 499 公斤， 增强热塑复合结构壁管总的米重为 170公斤， 折合材料成本降低至全塑管的 25% ， 消耗的聚乙烯为 85公斤仅为全塑管的 17% 。 在全系列规格尺寸中增强热塑复合结构壁管的材料成本不到全塑缠绕结构壁 管的三分之一 , 消耗的聚乙婦材料不到全塑管的五分之一，在塑料原材料价格爆涨的经济形势下是非常有价 值的应对措施。
增强热塑复合结构壁管既保留了塑料管材具有优良的水力特性，极强的内外防腐能力及适度的轴向柔韧 性等优点， 又以大弹性模量增强材料优化支撑结构， 可使管材以较低的材料成本， 具备抵抗土壤栽荷的足够 环刚度， 因此具有卓越的综合性能。

增强型材成型机的辊压成型轮上有动力输入， 当增强型材进入时会由于摩擦力的作用而被推动向前移 动。 当增强型材在经过增强型材成型机时， 增强型材经过若千组前辊压成型轮组（其由上辊轮 401和下辊轮 402组成） 时， 由平直的 "Γ 形增强型材逐渐成型为如图 1 3所示的增强型材的结构形式。

初步成型后的增强型材继续辊压， 由于后辊压成型轮组的下轮 404 的槽间距比前辊压成型轮组的下辊 轮 4G2的槽小， 增强型材会被再次将压， 开口的部位被桥压而贴合在一起， 终形成如图 15所示的所需要 的增强型材结构。

送带机 12的作用是将带材 23输送至设置在其后端的管材缠绕笼 17内， 并为带材 23的缠绕过程提供 动力。增强热塑复合结构壁管带材 23通过牵引机 11后进入缠绕机中的送带机 12, ^牵引机 11和送带机 12 的共同作用下， 带材 23连续不断地进入管材缠绕笼 17中。
管材缠绕笼 17是增强热塑复合结构壁管生产的主要设备，它包括机架、由压合外辊 171、压合内辊 172、 压合外定径辊 173、 以及以压合外定径辊 173为起点， 沿缠绕管外圆周导向的一组间隔布置的外定径辊 174 组成的卷绕机构。 卷绕机构的作用是使平直带材弯成一定弧度。 压合外辊 171与压合内辊 172位于带材 23 进入管材缠绕笼 17的入口。 压合外定径辊 173设置在压合外辊 171和压合内辊 172之后。 压合内辊 172设 置了位置调整机构， 其作用是调整平直带材的压弯弧度。
在本实施例中，压合内辊 172为主动辊，它通过链条传动机构由电机 123带动与送带机 12的送料辊 121 同步驱动。
在其他实施例中， 压合外辊 171与压合内辊 172同时为主动辊， 其中压合外辊 171通过链条传动机构 由电机 123带动与送带机 12的送料辊 121同步驱动。压合内辊 172与送带机 12的送料辊 121之间通过链条 传动保持同步驱动。
压合外辊 171、 压合外定径辊 173、 间隔布置的多个外定径辊 174为槽辊， 其开槽不仅容纳增强热塑复 合结构壁管带材 23的加强肋， 辊轮开始端设置的挡块或台阶还作为缠绕成管材过程中的螺旋导向槽， 按螺 旋升程的展开图间隔布置 , 以压合外定径辊为起点， 沿带材宽度方向两侧的加强肋的外侧面设置的可沿带材 宽度方向挤靠的橫向受力面， 与缠绕机上外径成型辊轮开始端设置的挡块或台阶挤靠， 并在多个上述挡块或 台阶的螺旋导向下，使带材卷绕一周时向前旋进一个带材宽度， 同时也使已卷绕成型的管材螺旋旋进一个带 材宽度。
在本实施例中， 一台缠绕机通过更换管材缠绕笼 17后可以生产多种管径和环刚度规格的增强热塑复合 结构壁管材。 在其他实施例中， 通过给压合外定径辊和间隔布置的外定径辊增加往复位置调整机构， 不需要 更换管材缠绕笼 17也可以生产多种管径和环刚度规格的增强热塑复合结构壁管材。
在本实施例中， 压合内辊 172还作为带材挤出焊接搭接处的压合辊， 相邻带材的基板搭接处同时被热 风加热器 15加热， 以提高带材基板搭接处的粘接强度； 平直带材的基板搭接处被焊条料挤出机 14连续挤出 焊条料， 并与卷绕一周后的相邻带材的基板搭接在一起， 搭接面被压合内辊 172的延伸部分进行滚压， 以加 强管材粘合面间的粘接强度， 压合并被卷绕成有间距螺旋加强结构的连续圆管状增强热塑复合结构壁管材。 焊条料挤出机 14的螺杆与无级调速装置相连， 可实现螺杆转速（即焊条料的挤出速度）平稳无级可调， 并 与带材缠绕输送速度的同步， 以实现管材的同步焊接成型。
请参阅图 21 , 图 21为本发明实施例提供的管材切割锯的结构示意图。
