Description

通讯、电力用检查井
技术领域
本发明涉及一种检查井,具体涉及一种通讯、电力用检查井。
背景技术
在通讯、电力设施铺设过程中,需要埋设通讯、电力检查井,方便今后的维护和检查。通讯、电力检查井按材料区分,主要有金属检查井、混凝土浇注检查井、塑料检查井和木质检查井。金属检查井成本高,费用贵;混凝土浇注检查井施工麻烦;木质检查井容易腐蚀,并且不牢固;塑料检查井近年来得到广泛使用,塑料检查井是由整块面板装配成框体,检查井的体积取决于插入导管的数量以及电工在井里操作所需的安全空间,所以有的检查井体积很大,那么就需要大面积的面板,而整块的大面积面板容易受到周围土、石的挤压变形,甚至断裂,造成塌方,危害井内通讯、电力设施的安全,如果加厚厚度,又提高了生产成本。
发明内容
本发明的目的是提供一种通讯、电力用检查井,结构牢固,体积小,操作使用安全,施工时间短,寿命长,维护费用低,密封性好,防水防潮。
本发明所述的一种通讯、电力用检查井,包括检查井井座,检查井井座外壁上设置线路进出管,线路进出管一端设置挡板,挡板上设置多个线路进出口,相邻线路进出口与线路进出口之间设置第一加强筋,线路进出口与线路进出管外壁之间设置第二加强筋;线路进出管与检查井井座连接处为圆弧。
检查井井座上端设有检查井人员入口。
检查井井座上方设置检查井井筒,检查井井筒上方设置检查井井盖。
检查井井座和线路进出管的外壁上设置网状加强筋。
检查井井座上的线路进出管个数为2‐4个。
圆弧大而光滑便于电线线路在检查井中的布道。圆弧机构能够减少电线线路在抽拉过程中的摩擦,减小对电线线路的损害,操作更为安全。提高线路电线的使用寿命,以及施工使用当中的安全性。
线路进出口优选6‐12个。线路进出管上设置的多个线路进出口能够将电线线路进行分类,降低线路的杂乱程度,操作更为准确,大大缩短检修时间。
圆弧所在圆的半径为R=50‐100mm。
检查井的井座部分采用高分子材料一次注塑成型。
以重量份数计,高分子材料原料配比为:HDPE:70‐90份,PP:12‐18份,LLDPE:2‐7份,色母:1‐3份。
以重量份数计,高分子材料原料配比为:HDPE:80份,PP:15份,LLDPE:5份,色母:2份。
LLDPE优选牌号7042,生产厂家为中国石化齐鲁石油化工公司。
HDPE优选牌号2480H,生产厂家为中国石化齐鲁石油化工公司。
PP优选牌号EPS‐30R,生产厂家为中国石化齐鲁石油化工公司。
色母为WDK:生产厂家为青岛威东科橡塑科技有限公司,WDK为PE管材专用黑色功能母粒。
本发明所用产品均为市售。
与现有技术相比,本发明具有以下有益效果:
本发明通讯、电力用检查井,结构牢固,体积小,操作使用安全,施工时间短,寿命长,维护费用低,密封性好,防水防潮。检查井强度增大,耐冲击,荷载能力增强;环刚度提高,和管道连接后,强度更大,整体稳定性提高。绝缘性能好,安全可靠,使用寿命提高3倍。改进后通讯、电力用检查井,原料熔体流动速率增大,产品成型质量好。
