泰安中联水泥有限公司(以下简称公司)的一条5 000t/d生产线,由南京凯盛国际工程有限公司EPC总承包,其中两个Φ25m×55m熟料筒库,储量为2×25 000t,预应力混凝土区段壁高43m,壁厚0.45m。该库设计施工使用了预应力混凝土,内置无粘结钢绞线,库体采用了清水混凝土滑模工艺进行浇筑,混凝土强度等级为C40。本文介绍熟料库无粘结预应力混凝土的特点、施工要求和注意事项,以及其使用效果。1无粘结预应力混凝土预应力混凝土是在构件加载前,预先用人工加力
Taian Zhonglian Cement Co., Ltd. (hereinafter referred to as the company) of a 5000t / d production line by the Nanjing Kaisheng International Engineering Co., EPC general contracting, of which two Φ25m × 55m clinker storage, storage capacity of 2 × 25 000t, pre The wall of the stress concrete section is 43m high and the wall thickness is 0.45m. The library design and construction of the use of prestressed concrete, built-in non-bonded strand, the reservoir body using a clear water sliding mode pouring process, concrete strength grade C40. This paper introduces the characteristics of unbonded prestressed concrete clinker, construction requirements and precautions, as well as its use effect. 1 unbonded prestressed concrete prestressed concrete is in the component before loading, pre-force with artificial
