Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering pipeline hoisting, and particularly relates to a convenient hoisting device for multi-specification concrete pipelines. Background Technique

[0002] At present, many cities in China are facing problems such as frequent urban waterlogging, water resource loss, and ecological environment damage. Urban underground drainage systems lag behind urban construction, resulting in urban waterlogging. As the phenomenon of waterlogging gradually increases, municipal engineering construction shows an increasingly important role, and municipal drainage pipelines are important projects in municipal engineering construction. However, due to the influence of many factors such as surrounding residents, urban traffic, and complex underground space pipe networks during the construction of drainage pipelines, the construction progress of pipelines is particularly important. If traditional hoisting methods such as steel wires, steel plates, and hooks are used for lowering pipes, the construction progress is slow, and the pipes are prone to offset and damage during the pipe lowering process, with a relatively high risk factor, and it is not applicable to concrete pipelines with multiple specifications and pipe diameters.

[0003] In the past, during the construction of municipal pipelines, the installation of pipelines mostly used methods such as steel wires and hooks for hoisting and lowering pipes. If steel wires are used for pipeline hoisting, although the manufacturing cost is relatively low, the risk factor during the construction process is relatively high, the pipeline is prone to offset, the pipeline positioning is difficult, the construction progress cannot be guaranteed, the labor cost is relatively high, and it is easy to cause damage to concrete pipelines, thus increasing the construction cost indirectly. If hooks are used for pipeline hoisting, the production of hooks is relatively difficult, and it is not applicable to the hoisting of concrete pipelines with multiple specifications and pipe diameters. The manufacturing cost is relatively high, and the phenomenon of hook detachment is prone to occur during the construction process, with a relatively high risk factor. Content of the Utility Model
