The invention discloses a straight-buried pipe aligning and connecting device and method. The straight-buried pipe aligning and connecting device comprises a fixed ring body and fixed lugs arranged onthe fixed ring body. The fixed lugs are arranged on the fixed ring body at intervals. Each fixed lug is provided with a base body and a clamping part. The diameter of the circle where the inner surface of each clamping part is located is larger than the outer diameter of a clamped pipe. Each clamping part is provided with a threaded hole and an adjusting bolt. The inner diameter of the fixed ringbody corresponds to the outer diameter of the pipes. The fixed ring body is a detachable ring body. The connecting method includes the steps of preparing the pipe aligning and connecting device according to needs, laying a basic sand-gravel cushion layer and digging a pipe aligning working pit, putting down the pipes, aligning, adjusting and fixing the pipes through the pipe aligning and connecting device, spot-welding and fixing the pipes, detaching the pipe aligning and connecting device, and conducting welding formally. By means of the device and method, the joint can be rapidly and stablyfixed during pipe aligning and connecting, the axis consistency of the pipes is improved, and the welding quality and welding efficiency are improved.
Description
technical field [0001] The invention relates to pipeline construction, in particular to a direct-buried pipeline-to-pipe connection device and a connection method thereof. Background technique [0002] Since most of the direct buried pipeline installation projects are livelihood projects and are closely related to people's lives, in order to meet the requirements of serving the people, on the premise of ensuring the construction quality and safety, completing the construction tasks according to the planned construction period is also an assessment of the organizational ability of the construction team Conditions, such as heating pipelines, gas pipelines, etc. Whether these projects that affect people's lives can be completed on schedule will be an important assessment indicator. [0003] According to previous engineering construction experience, it is found that the construction progress of pipeline trench earthwork and welding can meet the requirements of project progress b...
