Anti-sedimentation joint structure of buried heat preservation steel pipes and construction method of anti-sedimentation joint structure

Abstract

The invention relates to an anti-sedimentation joint structure of buried heat preservation steel pipes and a construction method of the anti-sedimentation joint structure. The anti-sedimentation joint structure comprises an anti-sedimentation joint connected between the heat preservation steel pipes by flanges, a metal bellows arranged on the anti-sedimentation joint in a sleeving manner, a heat shrinkable sleeve arranged on the metal bellows in a sleeving manner, and glass wool arranged between the anti-sedimentation joint and the metal bellows in a filled manner, wherein the end parts of the metal bellows are positioned on the outer side surfaces of the adjacent heat preservation steel pipes. The anti-sedimentation joint is wrapped with the glass wool, so that the heat preservation function is exerted, and the energy loss is reduced; and the metal bellows has certain rigidity, can prevent the glass wool from being compressed, exerts the function of protecting the glass wool, and further has a waterproof effect. The anti-sedimentation joint structure has the conventional building sedimentation absorption function, can exert the heat preservation function and the waterproof function, reduces the energy loss, prolongs the service life of a product, and improves the building construction quality.

Description

technical field [0001] The invention relates to the field of building construction, in particular to an anti-subsidence joint structure of buried thermal insulation steel pipes and a construction method thereof. Background technique [0002] Cold and hot water anti-settling joints are widely used in group projects for centralized cooling and heating. Cold water and hot water for air conditioning are provided by the centralized cooling, heating and power cogeneration energy center, and then transported to each cooling and heating facility through the underground pipe network. of monomers. [0003] Traditional anti-sedimentation joints can only meet the subsidence absorption function of the monomer, and do not have thermal insulation and waterproof performance. Therefore, when the pipe network is in normal operation, the loss of cooling and heat at the anti-settling joints is relatively large, which not only causes waste of energy, but also greatly The service life of the ant...
