Fabricated telescopic manhole
The invention discloses a fabricated telescopic manhole, and belongs to the technical field of manhole production and construction. A rib-free concrete manhole is located in the ground surface, and around hole stepped opening in the top is covered with a manhole cover; a ribbed concrete manhole is formed below the rib-free concrete manhole; a series of fabricated telescopic manhole units are matched with one another level by level, and annular teeth and annular grooves which are both located at the same height of the adjacent fabricated telescopic manhole units of the previous level are matched with arc-shaped grooves and arc-shaped teeth of a plurality of clamping pieces with toothed grooves which are evenly distributed in the circumference. The fabricating speed is high, the cost is low, the length of the manhole can be adjusted at will, components are very convenient to transport, the waterproof performance is good, joints have good durability, and construction and maintenance areconvenient.
本发明公布了一种装配式伸缩人孔，属于人孔生产与施工技术领域。无肋混凝土人孔位于地表，顶部圆孔阶梯口上盖人孔盖；在无肋混凝土人孔的下方为带肋混凝土人孔；一系列装配式伸缩式人孔单元一级一级相互契合，位于相邻上一级的装配式伸缩式人孔单元的同一高度的环齿、环槽上与若干个在圆周上均匀分布的带齿槽卡件的弧形槽、弧形齿相互契合。本发明装配速度快、成本低，人孔长度可以任意调整，且构件运输十分便利，不仅防水性能好，而且接缝具有良好的耐久性，便于施工与维护。
