The invention discloses a manhole opening device and a using method thereof. The manhole opening device comprises an opening frame with the telescopic length, sliding assemblies arranged on the two sides of the opening frame in a sliding mode, and sleeve rod assemblies arranged on the sliding assemblies in a rotating mode and with the telescopic length. The length of the inner frame of the trepanning frame is adjusted to be equal to the diameter of the arc section of the manhole, then the sliding assembly is moved to the center of the sliding groove of the trepanning frame, the scribing radius can be rapidly adjusted, the semi-arc section of the manhole can be rapidly drawn, and then the linear section of the manhole can be drawn through the inner frame edge in the width direction of the trepanning frame. Therefore, drawing of the contour line of the manhole is completed, the manhole opening efficiency can be improved, potential errors caused by manual construction are reduced, and a foundation is laid for subsequent opening in a segmented structure.

    本发明公开了一种人孔开孔装置及其使用方法,所述装置包括长度可伸缩的开孔框架、滑动设置在开孔框架两侧的滑动组件、以及转动设置在滑动组件上的长度可伸缩的套杆组件。本发明通过将开孔框架的内框长度调整至与人孔的圆弧段直径相等,再将滑动组件移动至开孔框架的滑动槽中央,可快速调整划线半径,能够快速画出人孔的半圆弧段,再利用开孔框架宽度方向的内框沿可画出人孔的直线段,从而完成人孔轮廓线的绘制,可以提高人孔开孔的效率,减少人为施工带来的潜在误差,为后续在分段结构上开孔打下基础。
