AI Technical Summary
During the PCCP pipeline connection process, a gap of a specified size needs to be reserved at the connection surface of two adjacent pipelines. However, due to the large size and weight of the pipelines, it is difficult to achieve a gap of a certain size during hoisting and installation.
A limiting clamp consisting of a pad and a crossbar is used. The thickness of the pad is equal to the gap width, and the length is greater than or equal to the gap depth. The pads are set on both sides inside the pipe and supported by the crossbar. With the help of tooling equipment or manual operation, the gap consistency is achieved, reducing construction risks.
It meets the standard requirements for pipe connection gaps, avoids misaligned installation, reduces safety risks for construction workers, and has a simple structure and is easy to use.
