Description

Groove pipeline construction device and construction method thereof Technical Field The invention relates to the field of pipeline construction, in particular to a trench pipeline construction device and a construction method thereof. Background Along with the continuous promotion of the urban process, the underground pipe network is used as a 'blood vessel' of the city, the construction scale of the underground pipe network is increasingly enlarged, and the requirements on construction quality and efficiency are also higher. In the conventional urban road trench pipeline construction process, a plurality of complex links such as trench excavation, substrate treatment, pipeline laying, pipeline butt joint, subsequent backfilling and the like are generally involved. At present, although some mechanized devices have been presented for each link of pipeline construction, for example, an urban road trench backfill construction device with publication number CN120401593B in the prior art, the device includes a trench, a pipeline disposed at the bottom of the trench, a support plate, a lifting and moving device, a limiting device, a positioning device, and other structures. According to the guide system formed by the support plate and the telescopic rotating wheel in the prior art, the guide system is matched with the pressing plate assembly driven by the electromagnet in the limiting device, accurate filling control can be carried out on the included angle area at the bottom of the pipeline, the problem that an overhead structure is easy to form in the area in the traditional process is effectively solved, and the uniformity of packing compactness is improved. However, while the above prior art technique achieves a better optimization in the specific process of "backfilling" the trench, there are significant drawbacks in the overall process of the overall pipe construction. Firstly, in the substrate treatment stage before the pipeline is in a ditch, the existing construction mode often relies on manual work or simple machinery to lay and level materials, the flatness and compactness of a cushion layer at the bottom of a ditch are difficult to ensure, and if the substrate is improperly treated, uneven stress or sedimentation deviation is extremely easy to occur after the pipeline is installed. The prior art CN 120401593B is mainly focused on backfilling compaction after pipeline installation, and lacks an integrated treatment means for paving and tamping and leveling the bottom of the trench. Secondly, in the pipeline laying and butt joint link, especially for concrete pipes or metal pipes with large caliber and high weight, the traditional hoisting mode is difficult to accurately control the posture of the pipelines, so that the pipe orifices of the two pipelines are difficult to align. Usually, auxiliary adjustment is carried out by manually matching tools such as a crowbar in the groove, so that the labor intensity is high, the butt joint precision is difficult to ensure, and the pipe orifice sealing structure is easy to damage. Moreover, the trench construction environment is complex, collapse risks exist in deep foundation pit operation, the existing construction equipment often lacks matched targeted safety support measures, and when constructors need to enter the trench to perform inspection or auxiliary operation, personal safety cannot be effectively guaranteed. Therefore, a comprehensive construction device integrating the functions of base spreading and tamping, accurate grabbing and butting of pipelines and safe support is needed, so as to solve the problems of scattered working procedures, difficult butting and uneven base treatment quality in the prior art. Disclosure of Invention The application mainly aims to provide a trench pipeline construction device and a construction method thereof, and solves the problems that in the existing trench pipeline construction technology, the leveling quality of a base pavement is difficult to control, the butt joint of pipelines depends on manpower and has low precision, and the lack of integrated construction and safety support equipment causes the rupture of a construction process and high safety risk. In order to solve the technical problems, the technical scheme adopted by the invention is that a trench pipeline construction device is characterized in that a plurality of travelling mechanisms are arranged on two sides of a frame, and a spreading device is arranged at one end of the frame and used for spreading and filling a trench; the other end of the device is provided with a tamping device which is used for tamping and leveling the material sprayed by the spreading equipment; a portal structure is formed in the middle of the frame, a pipe grabbing butt joint device is arranged on the portal structure, and the spreading equipment, the tamping device and the pipe grabbing butt joint device are integrated on one frame; the pipe grabbing and butting device is
