Embodiment 2
[0033] In the heat preservation and heating device used in the low temperature environment of a culvert described in Example 1, there is a left outer edge plate 12 between the inner arc plate and the left wall plate, and the inner arc plate and the upper wall There is an upper outer edge plate 13 between the plates, a right outer edge plate 14 between the inner arc plate and the right wall plate, and a lower outer edge plate between the inner arc plate and the lower wall plate. Along the plate 15, the left outer edge plate has a set of left fixing holes 16, the upper outer edge plate has a set of upper fixing holes 17, and the right outer edge plate has a set of right fixing holes 18. Said lower outer edge plate has a group of lower fixing holes 19.
[0034] The outer edge plate makes the assembly between the inner arc plates convenient and fast. After the inner arc plates are connected, it is firm and stable, and can fix the thermal paste well, and the heating effect for the ...
Embodiment 3
[0036] In the heat preservation and heating device used in the low-temperature environment of a culvert described in Example 2, when the left and right sides of the inner arc plates are overlapped and connected, the left outer edge plate and the right outer edge plate are superimposed, and the The left fixing hole and the right fixing hole coincide and are fixed by bolts 20. When the upper and lower parts of the inner arc plate are overlapped and connected, the upper outer edge plate and the lower outer edge plate are superimposed, and the The upper fixing hole is overlapped with the lower fixing hole and fixed by bolts.
[0037] The inner arc plates fixed by bolts are firm and stable, safe to use and effective to use.
