Problems solved by technology

[0004] 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

[0029] A heat preservation and heating device used in a low-temperature environment in a culvert, the composition of which includes: an inner arc plate 1, and the inner arc plate is sequentially connected to a left wall plate 2, an upper wall plate 3, a right wall plate 4, and a lower wall plate 5, The left wall, the upper wall, the right wall, and the lower wall are connected by a steel mesh 6, and the steel mesh is fixedly connected to a set of support rods 7, and the The support rods are arranged horizontally and then vertically. The inner arc plate is provided with a set of material openings 8. The charging openings are arranged horizontally and then vertically. The inner arc plate and the steel mesh There is a hot post 9 between them, the hot post is bonded to the hard strip 10, and the bottom of the hard strip is provided with an inverted U-shaped bayonet 11, and the inverted U-shaped bayonet is snapped into the The support rod described above is fixed.

[0030] The lef...

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.

The product comprises the following components: an inner arc board, the inner arc board is sequentially connected with a left wall board, an upper wall board, a right wall board and a lower wall board, the left wall board, the upper wall board, the right wall board and the lower wall board are connected through steel meshes. The steel mesh is fixedly connected with a group of supporting rods, the supporting rods are transversely arranged and then vertically arranged, theinner arc board is provided with a group of charging ports, the charging ports are transversely arranged and then vertically arranged, a hot paste is arranged between the inner arc board and the steel mesh, the hot paste is bonded with a hard strip board, an inverted U-shaped bayonet is formed in the bottom of the hard strip board, and the supporting rods are clamped into the inverted U-shaped bayonet to be fixed. The heat preservation heating device is used for heat preservation heating in the culvert low-temperature environment.

Description

[0001] Technical field: [0002] The invention relates to a heat preservation and heating device used in a low-temperature environment of a culvert and a use method thereof. [0003] Background technique: [0004] 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 or death. [0005] Invention content: [0006] The object of the present invention is to provide a thermal insulation and heating device and a method of use that can heat and insulate concrete in a culvert, improve the quality of the culvert, and have a good use effect in the low-temperature environment of the culvert. [0007] Above-mentioned purpose realizes by following technical sch...
