SUMMARY

[0005] In order to adjust the size of the laying area, the present application provides a pipeline installation structure and a jacking method.

[0015] Optionally, a support plate for supporting the pipeline is slidably mounted on the top wall of the support strip; the limiting member comprises a limiting strip and a return spring, the limiting strip is connected with the support plate, and the limiting strip is slidably mounted between the limiting area and the limiting groove; the return spring is mounted between the support plate and the support strip, and the return spring normally keeps the limiting strip in the limiting area; when the support plate is supported on the pipeline, the support plate sinks and forces the limiting strip to be clamped in the limiting groove.

[0027] In summary, the application has at least one of the following beneficial technical effects:

[0028] 1. By arranging the mounting seat and the adjusting member, the plurality of support strips provide a support carrier for laying the pipeline. When the size of the laying area needs to be adjusted, the pipeline above the support strip is lifted, then the two mounting seats are moved to a suitable height, and the position between the mounting seat and the mounting rod is fixed by the adjusting member, so that the size of the laying area is adjusted, the possibility that the size of the laying area is too large or too small when the pipeline is laid is reduced, and the space utilization is improved.

[0029] 2. By gradually reducing the height of the reinforcing strip from the middle position to both ends, the shape of the reinforcing strip forms an arc-shaped arch structure, which greatly improves the support effect of the reinforcing strip on the support strip, thereby reducing the possibility that the support strip is deformed under the weight of the pipeline.

[0030] 3. By the setting of the pull ring and the pull piece, the pipeline is laid on the top wall of the support strip, the weight of the pipeline is transmitted to the reinforcing strip, and then transmitted to the two mounting seats through the two ends of the reinforcing strip, so that the two mounting seats have a mutual away thrust, the two pull rings are driven to each other by the pull piece, so as to balance the thrust received by the mounting seat, and further reduce the possibility of deformation of the mounting rod under the action of the thrust of the mounting seat; on the other hand, the pull piece forces the two pull rings to approach each other, so that the pull ring can pull the adjusting sleeve, and force the adjusting sleeve to tightly abut against the peripheral wall of the mounting rod, reduce the possibility of free rotation of the adjusting sleeve, and improve the connection stability between the adjusting sleeve and the mounting rod.
