Problems solved by technology

[0002] The concrete in the culvert cannot be constructed normally in a relatively low temperature environment. If the strength of the concrete does not meet the requirements, the quality of the culvert will not meet the design requirements and cannot be used normally. There will also be safety hazards. Once an accident occurs, it will cause Great economic loss, and may cause personal injury

Embodiment 1

[0024] An insulation heating device used in culvert low temperature environments comprising: an internal arc plate 1, the inner arc board sequentially connected to the left wall plate 2, the upper wall plate 3, the right wall plate 4, the lower wall plate 5, The left wall panel, the upper wall plate, the right wall plate, the lower wall plate, and the lower wall plate is connected to the steel mesh 6, and the steel mesh is fixedly coupled to a set of rod 7, the The rod is arranged laterally, and then vertically, the inner arc plate opens an assembly port 8, which is arranged laterally, and vertically, the arc plate and the steel mesh. There is a hot post 9, the thermal post bonds the hard strip 10, the bottom of the hard bar, has an inverted U-shaped bayonet 11, and the down-U-shaped bayonet card The rod is fixed.

[0025] Left panel, upper wall, right walled, lower wall plate, can form a frame, circle the heat posts after assembly, do not ran out the range of the internal arc, ca...

Embodiment 2

[0028] Embodiment 1 The heat preservation heating device used in the culvert low temperature environment, the arc plate and the left wall panel having left outer panel 12, the inner arc plate and the upper wall The board has an upper alternate along the plate 13, and the inner arc plate has a right outer panel 14 between the right wall plate, the inner arc plate and the lower wall plate. Along the board 15, a set of left fixing holes 16 are opened along the left outer panel, and the upper and outer panels are opened, and a set of right fixing holes 18, the right outer panel 18. An additional set of fixing holes 19 are opened apart from the panel.

[0029] The outer edge is convenient when assembling the inner arc plate, fast, stable, stable, stable, and well-stable in the arc board, and the heating effect of the condensed concrete is good.

Embodiment 3

[0031] Example 2 The insulation heating device used in the culvert low temperature environment is connected between the left and right of the arc plate, and the left outer panel is superimposed on the right outer panel. The left fixing hole is fixed by a bolt 20 by a bolt 20, and the upper and outer panels are laminated, and the upper exterior panels are superposed along with the upper and lower panels. The upper fixing hole is rejected by the lower fixing hole by the bolt.

[0032] Strust, stable, safe use, and good use effect.
