[0002] Use the conduit method to pour bentonite cement mortar underwater. Due to the small proportion of bentonite cement mortar, it is difficult to pour it in with the ordinary conduit method. In this case, a pressure pump must be used to pass through the pipeline, and the conduit will press it into the groove. The connection with the conduit is flanged, which is labor-intensive and time-consuming

Description
1. Technical field [0001] The invention relates to a connector for conduit filling with underwater swelling and cement mortar, in particular to a pressure grouting connector. 2. Technical background [0002] Use the conduit method to pour bentonite cement mortar underwater. Due to the small proportion of bentonite cement mortar, it is difficult to pour it in with the ordinary conduit method. In this case, a pressure pump must be used to pass through the pipeline, and the conduit will press it into the groove. The connection with the conduit is flanged, which is labor-intensive and time-consuming. 3. Contents of the invention [0003] The invention provides a threaded connection pressure grouting connector, which can conveniently and quickly connect pipelines and conduits. [0004] The present invention is achieved through the following technical solutions: [0005] A pressure grouting connector, including a pipe cap, a wire cap, an O-ring, an outer wire, etc. The upper e...
