Description

一种带自清污功能的可伸缩导杆
技术领域
本实用新型涉及建筑施工领域,具体是一种带自清污功能的可伸缩导杆。
背景技术
目前,在施工地下室上部带有空孔的长螺旋压灌桩时,灌注桩身下部的混凝土后,空孔的护孔套管与钻杆有一定的间隙,导致钻杆上的泥土掉落至桩顶,污染桩顶尚未凝结的混凝土,插入钢筋笼时会将泥土带入桩身内,影响桩顶部的混凝土质量,无法达到施工质量要求,目前只能将混凝土灌满桩孔,然后凿掉空孔部分的混凝土,造成了极大的浪费,大幅增大了工程造价。
发明内容
本实用新型要解决的技术问题是提供一种结构简单、设计新颖、能有效清除带有空孔的长螺旋压灌桩施工中所产生的污染物的可伸缩导杆。
本实用新型的技术方案是:一种带自清污功能的可伸缩导杆,包括导杆本体,其特征在于:所述导杆本体由不同直径可自伸缩的导杆从内到外套接构成,其中直径最小的导杆通过转动部件一和钢丝绳与桩机顶部的鹤嘴滑轮相连,所述直径最小的导杆底部设置有月牙刀,所述月牙刀上设置有清污斗。
所述清污斗由圆环、多个锥形活瓣叶片、支架构成,所述支架设置在圆环中间,并通过螺栓固定在月牙刀两端,所述锥形活瓣叶片尾部通过转动部件二固定在圆环的外缘上,头部设置有与桩机顶部的鹤嘴滑轮相连的拉绳。
所述拉绳通与桩机顶部的鹤嘴滑轮相连。
所述多个锥形活瓣叶片合拢后成圆锥体。
本实用新型对传统长螺旋钻机用导杆进行改进,在原导杆底部设置了可方便下钢筋笼的月牙刀,并在月牙刀上设置有可清除桩内污染物的清污斗,有效的解决了,长螺旋钻机用于地下室带空孔桩基施工时,产生的污染物无法取出的技术难题,突破了长螺旋钻机用于地下室带空孔桩基的施工瓶颈,扩大了长螺旋钻机的使用范围,大幅提高了桩基的施工速度和效益,确保了桩身顶部质量,因此该导杆具有广阔的市场空间。
附图说明
图1是本实用新型可伸缩导杆剖视图;
图2是本实用新型可伸缩导杆清污时的使用状态图。
具体实施方式
一种带自清污功能的可伸缩导杆,如图1、2所示,包括导杆本体,所述导杆本体由不同直径可自伸缩的导杆1从内到外套接构成,其中直径最小的导杆2通过转动部件一3和钢丝绳4与桩机顶部的鹤嘴滑轮相连,所述直径最小的导杆2底部焊接有月牙刀5,所述月牙刀5上可安装清污斗6,所述清污斗6由圆环7、多个锥形活瓣叶片8、支架11构成,所述支架11设置在圆环7中间,并通过螺栓固定在月牙刀5两端,所述每个锥形活瓣叶片8尾部通过转动部件二9固定在圆环7的外缘上,头部设置有与桩机顶部的鹤嘴滑轮相连的拉绳10。
本实用新型带自清污功能的可伸缩导杆的工作原理为:在带空孔的桩基施工中,使用长螺旋钻机完成钻孔和压灌混凝土施工提出钻杆后,采用专用振动器夹住可伸缩导杆1,将其振入至混凝土表面下部20公分处,然后通过卷扬机向上提起拉绳10,使得锥形活瓣叶片8合拢形成圆锥体清污斗6,再用卷扬机向上提起钢丝绳4带动清污斗6至桩孔口外,完成桩内清污工作;
采用专用振动器和可伸缩导杆1将钢筋笼振送至设计深度,然后提出可伸缩导杆1,完成插入钢筋笼的工作。
以上所述,仅为本实用较佳的具体实施方式,但本实用新型保护范围并不局限于此,根据本实用新型的技术方案及其发明构思加以等同替换或改变,都应涵盖在本实用新型的保护范围之内。
