Background
With the construction of subway systems and the improvement of old urban buildings, more and more foundation pit excavation construction is carried out in cities, and the main construction method is open excavation. Before open cut construction excavation, existing concrete pipelines need to be cut off and plugged, and untight plugging can cause water in the existing pipelines to seep into a foundation pit or even cause water to be poured into the foundation pit in the excavation process of the foundation pit.
In the prior art, the blocking of the cut concrete pipeline is mostly filled by adopting brick masonry or concrete. This method requires manual work to be performed inside the pipeline. The problem that exists in this kind of current method is because space is limited, and manual construction can't be with concrete or brick brickwork with all gaps packing in the pipeline closely. When resuming its original drainage function after the pipeline shutoff, if water pressure too big can lead to along not having the closely knit gap of shutoff to the foundation ditch internal water seepage, gush water, have great potential safety hazard.
In published patent documents, for example, chinese patent application No. cn202120187831.x discloses a temporary blocking structure for a drainage pipeline, which includes a pipe cover, a connecting rod is slidably connected to the pipe cover, a clamping member that deforms along with the displacement of the connecting rod is disposed between the connecting rod and the pipe cover, and a limiting member that limits the sliding of the connecting rod through a screw thread is disposed on the pipe cover; the clamping piece is of a two-hinged-connection-rod structure, one end of the clamping piece is hinged to the outer peripheral surface of the connection rod, and the other end of the clamping piece is hinged to the pipe wall; the limiting piece is a nut and is rotatably arranged on the pipe cover; the connecting rod is in threaded connection with the nut.
Although the problem that manual construction cannot be carried out due to limited space is solved in the prior art, the following problems still exist: the plugging cover is stressed unevenly to cause untight sealing; the clamping piece is easy to damage the wall of the concrete pipe; the manufacturing cost is high.
