Embodiment Construction

[0015] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 , figure 2 , image 3 As shown, the thermal insulation prefabricated direct-buried pipe includes precast concrete layer 1, insulation layer 2 and protective layer 3 arranged sequentially from inside to outside. A layer 101 and an outer layer 102 are formed. 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 connecting pieces 4 . The outer layer 102 is provided with openings 5 ​​at both ends.

[0017] Such as Figure 4 As shown, in the preferred embodiment, the openings 5 ​​are two of different sizes arranged along the pipe wall, the precast concrete layer 1 is embedded with seamless steel pipes, the insulation layer 2...

Abstract

The invention discloses a heat-preserving prefabricated direct-buried pipe, relates to a composite pipe, and is used for solving the problem that the existing direct-buried pipe is easy to fall off when installed by a crane. It includes a prefabricated concrete layer, an insulation layer and a protective layer arranged sequentially from the inside to the outside, the edges of both ends of the precast concrete layer leak out of the protective layer, the precast concrete layer is composed of an inner layer and an outer layer, the inner layer and 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 invention relates to a composite pipe, in particular to a prefabricated directly buried pipe with thermal insulation. Background technique [0002] The direct buried pipe is suitable for heat preservation and cold preservation projects of various media in the range of -50°C to 150°C. It is widely used in heat preservation and cold preservation projects in urban central heating, warm rooms, cold storage, coal mines, oil ports, and chemical industries. [0003] The direct buried pipe can be buried directly in the ground or in the water. The construction is simple and fast, and the overall cost is low. However, when the existing direct buried pipe is installed by a crane, the hook directly hangs on the nozzle of the direct buried pipe. The tube is easy to fall off, which poses a safety hazard. Contents of the invention [0004] The purpose of the present invention is to provide a safe hoisting thermal insulation prefabricated direct buried pipe. F...
