Detailed Implementation

[0018] like Figure 1 As shown, a trench pipe spacing fixing device is mainly used in the laying of prefabricated direct-buried insulated pipes 1 and related operations. As the object of pipe installation, the spacing between two adjacent prefabricated direct-buried insulated pipes 1 is quite important for the quality of the project, and the spacing has fixed requirements according to the pipe diameter. In order to ensure the spacing between adjacent prefabricated direct-buried insulated pipes 1, this utility model provides a trench pipe spacing fixing device.

[0019] This utility model includes two arc-shaped pressure plates 2, an upper support component 3, a middle support component 4, and a lower support component 5. The two arc-shaped pressure plates 2 are disposed between two prefabricated direct-buried insulated pipes 1, and are tightly attached to the outer wall of the prefabricated direct-buried insulated pipes 1. The upper support component 3, the middle support component 4, and the lower support component 5 are respectively disposed at the upper, middle, and lower positions of the arc-shaped pressure plates 2.

[0020] The upper support assembly 3 and the lower support assembly 5 are symmetrically arranged with the middle support assembly 4 as the center. The middle support assembly 4 is horizontally arranged on the line connecting the midpoints of the two arc-shaped pressure plates 2. The length of the middle support assembly 4 is the pipe spacing. By controlling the length of the middle support assembly 4, the spacing between the two prefabricated direct-buried insulated pipes 1 can be guaranteed.

[0021] This utility model effectively increases the spacing between two prefabricated direct-buried insulated pipes 1 by simultaneously setting support components at the top, middle, and bottom, and by setting multiple sets of groove spacing fixing devices at intervals along the length of the prefabricated direct-buried insulated pipe 1. This utility model has the advantages of convenient installation and dismantling and wide applicability.

[0022] The main components of the trench pipe spacing fixing device have been described in detail in the above embodiments, but the specific structure of the components has not been described in detail.

[0023] The arc-shaped pressure plate 2 includes a base plate 23. In practice, the base plate 23 can be made of flat iron, which can be bent freely to fit tightly against the tube wall. Ear plates 21 are provided at both ends of the base plate, and a connecting sleeve 22 is provided at the center of the base plate 23. The center line of the connecting sleeve 22 coincides with the center line of the base plate 23.

[0024] The upper support assembly 3 includes two end connectors 31, two support rods 32, and a central connecting sleeve 33. The two end connecting sleeves 32 are respectively connected to two ear plates 21. One end of the end connecting sleeve 32 is provided with a pin hole for connection with the ear plate 21, and the other end is provided with an internal thread hole.
