Description

Technical Field

[0001] The utility model relates to the field of pipeline construction, in particular to a large-diameter concrete casing inner steel pipe crossing construction device. Background Art

[0002] Large-diameter concrete casing crossing plays an important role in the construction of domestic long-distance pipeline projects. During the crossing construction process, due to the influence of equipment capacity, geological conditions, process methods, and environmental factors, there are great difficulties in controlling the direction of large-diameter concrete casing crossing. For example, in the case of relatively simple geology, semi-automatic crossing and hand-dig pipe jacking crossing are used to carry out steel pipe crossing construction in large-diameter concrete casing. However, since the steel pipe is also a large-volume steel structure during the construction process, it is easy to cause disturbance to the outer concrete casing when using semi-automatic crossing and hand-dig pipe jacking crossing, affecting the installation and pre-embedded quality of the concrete casing. In addition, the above construction method is not applicable when constructing long pipelines. At the same time, the above construction method is not applicable to the construction of steel pipe crossing in large-diameter concrete casing under complex geology.

[0003] In order to solve the above problems, a large-diameter concrete casing inner steel pipe crossing construction device is disclosed in the utility model patent with authorization announcement number CN218063645U. The device moves the steel pipe by setting a mobile vehicle and a track, thereby solving the above problems. However, when the device is in use, there are still problems such as: the device cannot adjust the height of the guide assembly, and it is difficult to adapt when the distance between the concrete casing and the inner steel pipe is different, which easily causes the inner steel pipe to be offset during construction.

[0004] Therefore, the utility model proposes a large-diameter concrete casing inner steel pipe crossing construction device to solve the above problems. Utility Model Content
