The invention discloses a one-time pre-embedded water stop joint for building construction engineering drainage. The one-time pre-embedded water stop joint comprises a stand column, and a first devicecavity is formed in the side wall of the stand column. A device groove is formed in the upper end of the stand column, and a driving motor is fixedly connected to the side wall of the stand column. An output shaft of the driving motor penetrates through the side wall of the stand column and extends into the first device cavity, and a first bevel gear is fixedly connected to the tail end of the output shaft of the driving motor. A second bevel gear is rotatably connected to the inner wall of the first device cavity, and a first threaded rod is fixedly connected to the end, away from the innerwall of the first device cavity, of the second bevel gear. The upper end of the first threaded rod penetrates through the inner wall of the first device cavity and extends into the device groove, anda first cylinder is connected to the upper end of the first threaded rod in a threaded mode. The one-time pre-embedded water stop joint is convenient to install, the waterproof performance around thewater stop joint after being fixed is good, the bad phenomenon of water seepage around the water stop joint can be avoided, and the construction quality and efficiency are improved.
Description
technical field [0001] The invention relates to the technical field of construction, in particular to a disposable pre-embedded water stop for drainage in house construction projects. Background technique [0002] At present, in the building installation and construction, the general method of fixing the water-stop section is: before the hanging hole, the reserved hole is chiseled into a bell mouth type, and the inner wall of the bell mouth is chiseled. Then place the water-stop section in the bell mouth, and shape the bottom with a mold. Formwork adopts shaped formwork to ensure the compactness of concrete pouring. The water-stop section is fixed by concrete filling and compaction between the water-stop section and the trumpet hole. The entrance of the hole is poured twice with fine stone concrete (mixed with expansion agent). Although this method can also play the role of fixing the water-stop section to a certain extent, there are also relatively large disadvantages. ...
