Description

一种自清洁异形实壁管及其安装方法 技术领域
本发明涉及一种实壁管及其安装方法，特别是一种自清洁异形实壁管及其安装方法。
背景技术
排污管道是城市排水系统以及工业排水系统中非常重要的设施。目前常见的排污管道有塑料管、复合材料管以及混凝土浇筑管等。这些管道的一个共同是其截面均为圆形。也就是说，目前采用的排污管道均为圆筒形管道。
众所周知，圆筒形的排污管道的优势在于，其截面积大，在同等大小规格的排污管道中，其排水能力最强。另外，其内部无棱角，不容易卡塞固体物。但是，根据本申请研究者多年的研究和经验的积累，发现我国目前的城市和工业排污系统仍然容易发生堵塞，尤其是在固体物较多的排污段，经常出现管道堵塞的情况。本研究者经研究发现，造成堵塞的主要原因在于，固体物容易沉积在管道的底部，而圆筒形的排污管在水流本身不够湍急的情况下，底部的水流速度是非常平缓的，也就导致了底部的固体物排出困难的问题，日积月累之后，沉积的固体物越来越多，也就造成了管道的堵塞。
基于此，本研究者从改变管道形状的角度对排污管道进行了改进，设计了一种能够提高排污能力，降低堵塞概率的排污管道。
发明内容
本发明的目的在于，提供一种自清洁异形实壁管及其安装方法。本发明的排污管道具有排污能力强，堵塞概率低，可自清洁的特点。
本发明的技术方案：一种自清洁异形实壁管，所述实壁管包括有实壁管本体，实壁管本体的截面呈瓜子型，截面轮廓较大的一端为圆弧形顶部，较小的一端为圆弧形底部，侧面为与圆弧形顶部和圆弧形底部相切连接的侧弧 部，侧弧部分别与圆弧形顶部和圆弧形底部所在的圆形的下半部分相切。
前述的自清洁异形实壁管，所述圆弧形底部的半径与圆弧形顶部的半径比为1:2-3。
前述的自清洁异形实壁管，所述圆弧形底部的半径与圆弧形顶部的半径比为1:2.5。
前述的自清洁异形实壁管，所述圆弧形底部的半径与实壁管本体内部的最大高度之比为1:6-8。
前述的自清洁异形实壁管，所述圆弧形底部的半径与实壁管本体内部的最大高度之比为1:7。
前述的自清洁异形实壁管，所述实壁管本体为塑料管、钢管、混凝土浇筑管或复合材料管材。
一种前述的自清洁异形实壁管的安装方法，是在安装架上开设与实壁管本体截面形状一致的限位孔，安装时在实壁管本体的两端分别套设1个安装架，即可完成实壁管本体的铺设和便于多段实壁管本体之间的拼接。
前述的自清洁异形实壁管的安装方法，当实壁管本体与所述限位孔同轴时，限位孔与实壁管本体之间存在0.1-0.5cm的安装间隙。
本发明的有益效果
本发明通过将排污管道的截面设计呈瓜子型，顶部与底部采用弧形设计，无棱角，而两侧的侧弧部自上而下逐渐向内侧倾斜。这种结构在排污的过程中，由于底部宽度大幅度变小，其排污宽度变窄，底部的单位截面积上受到的水流冲击力大幅提高，固废下降在管道底部时，很容易在水流较大冲击力作用下排出，从而减少了固废在底部沉降堆积的可能，大大提高了排污能力，降低了堵塞概率，具有自清洁的优点。同时，本发明还对管道的圆弧形顶部和圆弧形底部的直径比例以及侧面侧弧部的夹角进行了设计，能够保证在提高排固废污染能力的基础上，还不影响排水的能力。
本发明的研究者进行了相关实验，分别制作了截面积一致的圆筒形塑料 管道和本发明所述的异形实壁管，其中异形实壁管的圆弧形底部的半径为16cm，圆弧形顶部的半径为39cm，异形实壁管本体内的最大高度为108cm(附图1所示)。
将圆筒形塑料管道和异形实壁管分别拼接至200m的长度，铺设在平整的地面上，倾斜角度均为10°。将碎石块、碎布片、垃圾袋和蔬菜叶混合后均分成2份，分别分散在圆筒形塑料管道和异形实壁管的底部，以灌满圆筒形塑料管道截面1/3高度左右的水流分别从圆筒形塑料管道和异形实壁管较高的一端自然流入，排水5min后观察管内的固废排出情况。重复试验3次，结果如下表：

在安装时，首先在安装架5(安装架5可为三角形或者方形)上开设与实壁管本体1截面形状一致的限位孔6，为了便于实壁管本体1插入限位孔6，通常将限位孔6的尺寸加工成稍大于实壁管本体1截面尺寸(整体间隙在0.1-0.5cm)，然后在实壁管本体1的两端分别套设1个安装架5，使实壁管本体1能够平稳的放置在铺设位置，从而实现管道的安装以及便于管道之间的相互连接。
