Background
Along with the continuous development of the economy of China, the construction of urban industrial parks is as well as fierce, along with the construction of industrial parks, the demand of central heating steam supply pipe networks is increased day by day, particularly under the background of carbon peak reaching and carbon neutralization, the nation sends out the notice about the reformation and upgrading of coal-electric units in the whole country, wherein the notice that the centralized heating demand needs to be fully expanded, the heat supply resources are integrated, the construction of matched heat network projects and old pipe network reformation projects are supported, the interconnection and intercommunication of heat networks in heat supply areas are accelerated, the networking operation of various heat sources is realized as early as possible, and the heating capacity of cogeneration units is fully exerted. The heat and power cogeneration unit is encouraged to properly develop long-distance heat supply projects on the premise of reasonable technical economy, industrial heat load enterprises are attracted to develop to the periphery of coal-storage power enterprises, and the heat supply range is expanded.
In most of pipe network designs at present, a pipeline bracket still adopts the traditional design thought, a steel plate is pre-embedded when a buttress is used for civil engineering, a rigid sliding bracket bottom plate is placed on the pre-embedded steel plate in parallel when the pipeline is installed in place, so that relative sliding is realized, but in the actual construction process, the pre-embedded steel plate on the buttress is probably not in a horizontal state and can incline towards a certain direction, the pipeline is fixed and can not be adjusted, the bracket bottom plate can not be completely parallel to the pre-embedded steel plate when the bracket is installed in place, the condition can cause that the sliding bracket can not smoothly slide relative to each other or even be blocked when the pipeline is used for heat supply, the sliding bracket becomes a fixed bracket, the buttress is required to bear great thrust, the caliber of a heat supply pipe network is small before, the problem that the sliding bracket is blocked can not be caused, but the problem that the sliding bracket is blocked can not appear increasingly collided with the heat supply demand, the steam pipe network is built larger and laid longer, more and more large-caliber high-temperature steam pipes are erected, the diameter of the pipe can reach 80cm or even larger, if the whole diameter of the heat insulation material on the outer surface is increased to 140cm, if the sliding support is still choked and locked in the operation process, the support pier can be damaged, the support pier can be overturned seriously, and great safety hazards exist.
At present, under the working condition that an embedded steel plate is not horizontal or a high-temperature steam pipe network on a sloping field needs to be obliquely laid, the inclination of one inclined side of a support is compensated by plugging a wedge-shaped gasket so as to ensure that the lower surface of a pipeline support is completely attached to the upper surface of the embedded steel plate as far as possible. However, this approach also has certain drawbacks: 1) because the inclined angles are different, the inclined plane angles of the wedge-shaped gaskets need to be matched with the inclined plane angles, and the wedge-shaped gaskets with different inclined plane angles are needed, so that the cost is increased; 2) the gasket needs to be fixed at the buttress upper surface, has increased a construction procedure to if the gasket does not fix well and drops from the buttress, can lead to the support can't laminate with the steel sheet of buttress upper surface is complete, causes the incident easily.
