Non-excavation electric power pipe pulling construction hoop type pipeline connecting device in complex environment

Abstract

The invention discloses a non-excavation electric power pipe pulling construction hoop type pipeline connecting device in a complex environment, the device comprises two MPP electric power pipes and two fastening mechanisms arranged outside the MPP electric power pipes, and a connecting mechanism is jointly connected between the two MPP electric power pipes in a sleeved mode. The two fastening mechanisms are detachably installed on the left side and the right side of the connecting mechanism correspondingly According to the invention, the connecting mechanism wraps a connecting opening between the two MPP electric power pipes, the good sealing effect can be achieved, water seepage in the MPP electric power pipes is prevented, the sealing effect is good, the fastening mechanism is convenient to clamp, the locking force is large, fixing is firm, and the stability is high; and the rubber pad can improve the close attaching degree between the MPP electric power pipe and the connecting mechanism, increase the friction force, give full play to the hooping force of the semicircular galvanized flat steel, ensure that the pipeline connection does not fall off, and can be popularized and used.

Description

technical field [0001] The invention relates to the technical field of road reconstruction, in particular to a hoop-type pipeline connection device for non-excavation electric pipe-drawing construction in complex environments. Background technique [0002] At present, as our country vigorously promotes the transformation and improvement of back streets and alleys and old residential areas, implements the spirit of the important instructions of the city's refined management level, improves the image of the city, and enhances the happiness and satisfaction of residents. The problem of renovation of the old street style is particularly prominent. In the construction of roadside poles and overhead lines involving "three lines" into the ground, the non-excavation pipe pulling technology of "not opening the road" and "running underground pipes" has been widely used. However, in residential areas where the environment is relatively complex, it is difficult to connect some pipe sect...

Problems solved by technology

The problem of renovation of the old street style is particularly prominent. In the construction of roadside poles and overhead lines involving "three lines" into the ground, the non-excavation pipe pulling technology of "not opening the road" and "running underground pipes" has been widely used. However, in residential areas where the environment is relatively complex, it is difficult to connect some pipe sections and open cut sections, the construction progress is relatively slow and there are large safety hazards

[0003] Existing pipeline connection devices are fixed with threads and screw holes at the joints, resulting in gaps in the joints, affecting the sealing degree of the joints, prone to leakage, and the vibration generated by the pipeline during use. For a long time, the connecting devices will become loose, which will affect the stability of the connection
