Study On Construction Technology Of Palms-together Dagoba In Famen Temple And Its Application

Palms-together Dagoba in Famen Temple has a special shape which is double fold,and ultra-limit high-rising structure, Many parts have beyond the specification requirements, and with the short construction period. so, The construction of the project is very difficult, this topic is According to the characteristics of the project and the problem in the stage of implementation and it carries out a series of theoretical studies,and summarize a series of special construction technology.These construction which reciprocating angel reach 36 degree like Palms-together Dagoba in Famen Temple, traditional climbing large formwork technology can not meet the construction requirements, in accordance with this strange structural shape, we researched and designed a specialized technique. Under the feature of the project which steel should build two layers, use the structure of steel and the programme of attached type. Use the Steel reinforced concrete column to be the supporting point, set the external beam as scaffolding; set a vertical track for the template, use the single template to promote; set the beam as horizontal track and supporting, add an intermediary agency between the beam templates. This scheme can be divided to five systems, they ‘re outside beam system, template system, the template constraint,template promoting system, safeguard system, this article has carried on the design to them one by one and checking them with the real construction load, it lays out the construction technological process which is inclined and lifted large formwork. As it turned out, this big template technique is convenient, flexible turnover, simple removingand it’s propitious to shorten the construction period, also reducing the construction costs.In order to ensure the ultimate configuration of this complex structure fixed the designing configuration, this article also designed construction technology for dynamic control of large inclined steel reinforced concrete which is based on the simulation technology, through construction simulation to find out the stability problem or security problem in the construction processing, to ensuring the default values of sloping structure which can be used on the construction by the way of Construction preset displacement analysis. Based on the construction simulation technique and Construction preset displacement analysis, to research the installation, measuring, controlling of the large inclined steel structure, construction skills and reinforce linking or removing the truss on this engineering.In order to get the service life of the high-strength and high-performance concrete of Palms-together Dagoba in Famen Temple can be 100 years, after researching, we decided to use the Dunshi brand concrete P.O42.5 which is from the Jidong Haidebao Fufeng cement company, the sandstone is from Wei He, the water reducing agent is PCA. The article also researched the mix ratio between the C35 cement and C60 cement and get the related technical parameters. In the light of the construction of over-thick wall, pumping construction in winter and the construction of structure durability, and successfully satisfied every performance requirements of cement requirements to this project, prevent many problems, such as temperature stress cracking, frozen damage,and durability problem. In this context, the research of the high performance concrete technique would made a reference to any other same kinds of constructions in the future.
