uncompensated

A new theory is advanced in the design of fixed base of the uncompensated heating supply pipe that is directly buried into ground.

　对无补偿直埋供热管道固定墩的设计提出新的想法,拟采用支架式固定支座代替混凝土固定墩,以避免原有固定墩体积大、工程造价高易下沉等缺陷,并对设计中管道轴向推力、土壤与管道摩擦力、地耐力等的计算及理论依据进行了阐述。

The theoretic basis of cover-type preheated and directly buried installation without expansion joint,the design parameter calculation and the construction technology requirements are analyzed.

分析了覆盖式预热无补偿直埋敷设的理论基础、设计参数计算及施工技术要求,结合工程实例,对某计算管段进行了设计计算。
