Detailed Description
The following provides a further description of the present invention with reference to the accompanying drawings and examples.
As shown in fig. 1 and 2, an existing pipeline casing installation assembly includes a hoisting module and a protection module; the lifting module comprises lifting ropes 3 sleeved at two ends of an existing pipe section 5, a cross beam 4 crossing the lifting ropes 3 at the two ends and a crow bar 1 for prying the cross beam 4 through the lever action, wherein one side of the crow bar 1 is a long rod for pressing down, the other side of the crow bar 1 is a short rod for upwarping, the middle of the crow bar is a supporting point, a platform for supporting the cross beam 4 is arranged on the short rod, and the supporting point is hinged to a support 2; the protection module comprises an upper pipe sheet 6 and a lower pipe sheet 7 which surround the existing pipe section 5 in a formed circle from top to bottom respectively, and the upper pipe sheet 6 and the lower pipe sheet 7 are all welded and fixed by adopting steel pipes and surrounding. During construction, the existing pipe section 5 is excavated, then the existing pipe section 5 is lifted by a simple prying tool (a wooden stick, an iron stick, a conventional crow bar and the like), a skid is placed at the bottom of the existing pipe section 5, then the lifting rope 3 is sleeved at the end part of the existing pipe section 5 through the bottom gap, the beam 4 is transversely crossed through the lifting ropes 3 at the two ends, then the support 2 is placed near the excavation groove, the platform on the short rod of the crow bar 1 is pressed upwards against the cross beam 4, the long rod of the crow bar 1 is pressed downwards, the cross beam 4 is pried up through the lever action, so that enough space is reserved below the existing pipe section 5, then, placing lower pipe pieces 7 below the existing pipe sections 5, resetting the existing pipe sections 5 after all the lower pipe pieces 7 are placed, enabling the lower parts of the existing pipe sections 5 to fall on the lower pipe pieces 7, finally covering the upper pipe pieces 6 on the upper parts of the existing pipe sections 5, enclosing the existing pipe sections 5 in a formed circle by matching with the lower pipe pieces 7, and welding and fixing the upper pipe pieces 6 and the lower pipe pieces 7; the assembly is simple to install, low in cost, safe in installation process and suitable for protecting pipelines which are not densely arranged.
As shown in FIG. 2, in the present embodiment, the lower tube sheet 7 occupies 1/3-1/2 of the circle formed by the enclosure, so that the welding points 8 at two sides can be arranged below the farthest end, and the welding points 8 are prevented from being directly exposed upwards. In this embodiment, the lifting rope 3 is a steel wire rope with connectors at two ends, the beam 4 is a channel steel or a steel pipe, and the upper pipe sheet 6 and the lower pipe sheet 7 are discontinuously welded. In the present embodiment, the pipe diameters of the upper pipe sheet 6 and the lower pipe sheet 7 are determined according to the diameter of the existing pipe section 5, for example, the diameter of the existing pipe section 5 is 100mm, the diameter is 150mm, and the diameter of the existing pipe section 5 is 50mm, the diameter is 100 mm.
