Description

Technical Field

[0001] The utility model relates to the technical field of sewage pipe suspension protection, and specifically, to a socket-type concrete sewage pipe suspension protection device. Background Technique

[0002] When large-scale underground space projects such as subways and utility tunnels are constructed in cities, the open-cut method is often used for foundation pit engineering. During the excavation process, existing pipelines are often encountered, which affects the excavation of the foundation pit. For sewage pipes built earlier, most of these pipelines are socket-type concrete pipe joints, and the socket and spigot are located within the foundation pit excavation range. In most cases, the existing concrete socket-type sewage pipes need to be excavated and then suspended in situ.

[0003] After retrieval, the utility model patent with the publication number CN214169076U discloses a socket-type concrete sewage pipe suspension protection device. Its technical solution is as follows: It includes retaining piles and a capping beam arranged on the retaining piles, and a Bailey beam is arranged on the capping beam; it also includes a fixed suspension assembly located at the socket and spigot of two sections of sewage pipes and a flexible suspension assembly located on a single section of sewage pipe on the Bailey beam; the fixed suspension assembly includes semi-circular ring plates located on both sides of the socket and spigot of two sections of sewage pipes, column assemblies are arranged above both ends of the semi-circular ring plates, screws are arranged above the column assemblies, and two column assemblies on the same side of different semi-circular ring plates are connected by a connecting rod; the flexible suspension assembly includes a flat sling, flower basket bolts are arranged at both ends of the flat sling, and the other ends of the flower basket bolts are arranged on the Bailey beam; this patent provides in-situ suspension protection for socket-type concrete sewage pipes that affect foundation pit excavation.

[0004] However, the above patent still has the following deficiencies: When installing and adjusting, the nut needs to be repeatedly screwed, and the height of the suspension assembly is adjusted through the cooperation of the nut and the screw, and the convenience during adjustment is poor; moreover, there are differences in the outer diameters of sewage pipes, and semi-circular ring plates with different inner diameters need to be equipped to wrap and support the lower part of the sewage pipe, which increases the difficulty of suspension protection. For this reason, we propose a socket-type concrete sewage pipe suspension protection device. Content of the Utility Model
