Research On The Construction Techniques Of The Industrial Remains Of The Third-front Movement In The Western Areas Of Hubei,Henan And Hunan Provinces

Since 1949,New China has undergone several tremendous social changes,among which the Third-Front Movement began in the early 1960 s.Faced with the unstable international situation at that time,the central government made a decision to build a strategic rear area,and carried out large-scale industrial construction in the deep valleys of southwest and northwest China,leaving behind a large number of industrial building remains for later generations.As an important type of modern heritage in China,these three-line construction remains have obvious characteristics of the times and buildings,and their factories have obvious characteristics of the built environment.The material technology of mining institutes and other units is a typical representative of the socialist construction period in our country.At the same time,in the course of many years of construction,a large number of economic construction modes have been accumulated,such as saving building materials,rapid construction,everyone can participate in,and the experience and lessons of disaster prevention and mitigation in remote areas.According to the decision of the CPC Central Committee,taking the BeijingGuangzhou Railway as the boundary,the western part of Hubei,Hunan and Henan provinces are divided into three lines.This paper chooses the three-tier Industrial Relics in Western Hubei,western Hunan and Western Henan as the main research object.On the basis of combing the historical background,studying the archives and drawings,and investigating the cases on the spot,it collects the cases extensively,and takes the Jiao-Liu Railway as the clue to connect the cases in series.As the core content of this paper,the research on the record of the construction techniques of factories,mines and institutes in the third-line construction will be carried out step by step from all levels.The first is to analyze the construction techniques of the specific cases of the third-line construction in Western Hubei,western Hunan and Western Henan;the second is to carry out the overall construction system and special construction techniques in the specific background of the three-line construction remains in Western Hunan,western Hunan and Western Henan.In a comprehensive summary,the overall construction system includes construction organization,building materials,structural system and detailed structure,and the special construction techniques under specific background include traditional house "Gan Da Lei" and modern assembled "big board building".Thirdly,it analyses the relationship between architectural form and content in the special period at that time,including "dry battle" and "big board building".The construction mode reflects the social background at that time.The following conclusions are drawn from the analysis: The construction techniques left over from the third-line construction reflect that in the difficult economic period,our country has adopted various construction methods adapted to local conditions in order to achieve the construction goal of "how fast,how good and how economical",so as to meet a large number of construction needs in a short period of time;ideologically,it is an important manifestation of the spirit of the third-line arduous struggle.
