挡热板

Our country firstly put forward such design principle of Qinghai-Tibet railway engineering as "lower temperature actively, reduce the heat into the subsoil, and assure the heat stability of frozen earth for the quality stability of construction", creatively adopt such corresponding measures of frozen earth construction problem as: for the poor frozen earth developing section, line should avoid as possible;for the geology of ice at high temperature and unstable frozen earth zone, the method of bridge instead of subgrade shall be adopted;in subgradeconstruction, such facilities as heat stick, rubble ventilation subgrade , rubble ventilation berm, ventilation pipe subgrade and laying heat preservation board etc shall be adopted to raise the stability of frozen earth subgrade;during the excavation of bridge, culvert , foundation pit and scouring prevention trough, creatively adopt single-tooth knapper and solve the problem of frozen earth excavation;during the construction of bridge and culvert, durable concrete and three-step maintenance method are adopted to assure the outside and inside beauty of structure.

我国在世界上首次提出"主动降温、减少传入地基土的热量、保证多年冻土的热稳定性，从而保证修筑在上面的工程质量的稳定性"的青藏铁路工程设计原则，创造性地采取了解决冻土施工难题的相应对策：对于不良冻土现象发育地段、线路尽量绕避；对于高温极不稳定冻土区的高含冰量地质，采取"以桥代路"的办法；在路基施工中采用了热棒、片石通风路基、片石通风护道、通风管路基、铺设保温板等多项设施，提高冻土路基的稳定性；在桥涵基坑、挡水埝基槽开挖中，创造性地应用了单齿破碎器，解决了冻土开挖难题；在桥涵工程施工中，采用了耐久性混凝土，采用了三步养生法，保证了结构物内实外美。

Only then will the charred heat shield be ejected.

只有在那时给烧坏的挡热板会给丢弃

VICO has made a large Sheet Coater for Vikram Sarabhai Space Centre, Trivandrum. It is used to coat 1.5meterx 2.5meter PolyImide Sheet which works as Heat Shield for the Satellite.

VICO为维克拉姆-萨拉巴航天中心生产了一大批薄板覆膜机，用于为1.5米*2.5米的聚酰亚胺板覆膜，该板是人造卫星的挡热板。
