Problems solved by technology

[0003] Buried pipes can be directly buried in the ground or in water. The construction is simple and fast, and the overall cost is low. However, when the existing buried pipes are installed with a crane, the hook directly hangs on the nozzle of the buried pipe. Easy to fall off, there is a safety hazard

Embodiment Construction

[0016] In order to enable those skilled in the art to better understand the present invention, the technical solutions of the present invention are further described below with reference to the accompanying drawings and embodiments.

[0017] like figure 1 , figure 2 , image 3 As shown in the figure, the thermal insulation prefabricated buried pipe includes a prefabricated pipe layer 1, an insulating layer 2 and a protective layer 3 which are sequentially arranged from the inside to the outside. The edges of both ends of the prefabricated pipe layer 1 leak out the protective layer 3. 101 and the outer layer 102, the inner layer 101 and the outer layer 102 are separated from each other to form a cavity, the inner layer 101 and the outer layer 102 are fixed by the connector 4, and the outer layer 102 is provided with openings 5 ​​at both ends.

[0018] like Figure 4 As shown, in the preferred embodiment, the openings 5 ​​are two of different sizes arranged along the pipe wa...

Abstract

The invention discloses a thermal insulation prefabricated buried pipe, relates to a combined pipe, and is used to solve the problem that the existing buried pipe is easy to fall off when installed by a crane. It includes a prefabricated pipe layer, an insulation layer and a protective layer arranged sequentially from the inside to the outside. The edges of both ends of the prefabricated pipe layer leak out of the protective layer. The outer layers are separated from each other to form cavities, the inner layer and the outer layer are fixed by connecting pieces, and openings are arranged at both ends of the outer layer. By setting the composite layer, it can not only ensure the tightness of the inner layer, but also ensure the safety of lifting.

Description

technical field [0001] The present invention relates to a combined pipe, in particular, to a thermally insulated prefabricated buried pipe. Background technique [0002] The buried pipe is suitable for heat preservation and cold preservation projects for conveying various media in the range of -50℃ to 150℃. [0003] The buried pipe can be directly buried in the ground or water, the construction is simple and rapid, and the overall cost is low, but when the existing buried pipe is installed by a crane, the hook directly hangs the nozzle of the buried pipe, so that when the buried pipe is lifted, the buried pipe It is easy to fall off and there is a safety hazard. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a thermal insulation prefabricated buried pipe that is safe for lifting. For realizing the above-mentioned technical purpose, the technical scheme adopted in the present invention is as follows: [0005] The thermal insulation p...
