Description

Technical Field

[0001] The utility model relates to an installation tensioning device for drainage pipes in the field of engineering construction, and particularly to an electric tensioner for double-wall corrugated pipes. Background Art

[0002] During the construction process of corrugated pipes, it usually involves the socket joint installation of two pipes. At present, most commonly, two methods are used to insert and tension the upstream and downstream corrugated pipes, namely manual tensioning or using an auxiliary tensioner. Among them, manual tensioning is simple in operation but time-consuming and laborious, with low work efficiency. And the commonly used pipe auxiliary tensioners on the market usually have poor adaptability of the snap ring size, and the snap ring needs to be frequently replaced when connecting pipes of different diameters. In response to this, the applicant has proposed a diameter-adjustable HDPE double-wall corrugated pipe installation tensioner (application number 2023222086502), which can be used for the docking tensioning of HDPE double-wall corrugated pipes with different diameters. However, this tensioner requires manual repeated operation of the ratchet wrench to tension the upstream and downstream double-wall corrugated pipes, which is time-consuming and laborious. Moreover, due to objective conditions such as the narrow construction site and limited working space for pipe installation, the above operation is rather inconvenient, thus reducing the construction efficiency.
