Long-distance horizontal hole concrete pouring device and pouring method
A long-distance horizontal hole concrete pouring device solves the problem that long-distance holes are not completely filled with concrete. The device comprises a concrete feeding device and a vacuumizing connector, a discharge hole of the concrete feeding device is communicated with the preformed hole; and the vacuumizing joint is communicated with the hole. Municipal comprehensive pipe galleries, underground passages and subway stations are gradually subjected to large-scale pipe jacking construction, the structure adopts prefabricated assembly components, the construction method is used for a certain pipe jacking underground excavation subway station, and in the project, the construction is carried out strictly according to specifications, design requirements and construction process key points in the concrete construction process of vacuumizing and pouring duct piece reserved holes, and the construction efficiency is greatly improved. And the concrete pouring quality of the project is guaranteed, and the expected effect is achieved. The device is simple in structure, convenient to mount and suitable for filling reserved holes under various long-distance and small-aperture working conditions.
一种长距离水平孔洞混凝土灌注装置，解决长距离孔洞填充混凝土不完全的问题。其包括混凝土进料装置和抽真空接头；所述混凝土进料装置的出料口与预留孔连通；所述抽真空接头与孔洞相通。市政综合管廊、地下通道以及地铁车站逐渐采用大型顶管施工，结构采用预制拼装构件，本发明用于某顶管暗挖地铁车站，在本项目抽真空灌注管片预留孔洞混凝土施工过程中,严格按规范、设计要求和施工工艺要点进行，保证该工程的混凝土灌注质量，达到了预期效果。该装置构造简单、安装方便、适应于各种长距离小孔径工况下的预留孔洞填充。
