Prefabricated integrated reinforced concrete inspection well and construction method thereof

CHENG QUAN'AN

The invention discloses a prefabricated integrated reinforced concrete inspection well and construction method thereof. The prefabricated integrated reinforced concrete inspection well comprises an inspection well body and a preformed hole. A pipeline and a connecting sleeve are connected into the preformed hole. The connecting sleeve is connected with the preformed hole through a bonding material. A plurality of expansion screws are arranged between the connecting sleeve and the wall of the inspection well body. The construction method comprises the steps that the pipeline is intercepted, theconnecting sleeve is formed at a pipe opening of the pipeline through a steel die, the preformed hole is drilled in the wall of the inspection well, marble glue or expansive cement mortar is smearedon the periphery of the wall of the preformed hole, the connecting sleeve is immediately inserted into the preformed hole to be compacted, and after the initial setting period, the expansion screws are driven into the four sides of the connecting sleeve to connect the wall of the inspection well with the connecting sleeve. The prefabricated integrated reinforced concrete inspection well and construction method thereof have the advantages of simple structure, reasonable design, simple and convenient pipeline installation, short pipeline installation time, high pipeline position accuracy, strongsealing performance, high overall strength and the like.

一种预制一体式钢筋混凝土检查井及其施工方法，包括检查井本体、预留孔，所述预留孔内连接有管道、连接套，所述连接套与预留孔通过粘结材料相连接，所述连接套与检查井本体的井壁之间设有若干根膨胀螺丝；截取管道，通过钢模在管道的管口处形成连接套，在检查井的井壁上钻取预留孔，在预留孔的孔壁一周涂抹云石胶或膨胀水泥砂浆，并立即将连接套插入到预留孔内压紧密实，待初凝期过后，在连接套的四侧打入膨胀螺丝来连接井壁与连接套；本发明具有结构简单、设计合理、管道安装简单方便、管道安装耗时短、管道位置正确率高、密封性能强、整体强度大等优点。
