Abstract: China attaches great importance to people's livelihood and gradually builds various types of water conservancy and hydropower projects. Concrete structures are widely used in water conservancy and hydropower projects. The construction technology of concrete structures is relatively special, and cracks often occur. However, there are many factors affecting the problem of concrete cracks. In order to improve the durability of water conservancy and hydropower construction projects, construction units need to strengthen the prevention and control of concrete cracks and maintain the stability of the operation of water conservancy and hydropower projects. This paper analyzes the causes of concrete cracks in the construction of water conservancy and hydropower construction, and puts forward targeted prevention measures to ensure the comprehensive benefits of water conservancy and hydropower construction.
Keywords: water conservancy and hydropower; construction engineering; concrete cracks; prevention measures
1 概述
近些年,我国不断扩大水利水电建筑工程施工规模,在施工过程中由于受各种因素影响会发生各种安全质量事故,威胁到人们的生命财产安全。在水利水电建筑工程施工中,混凝土裂缝属于常见的问题,影响到水利水电建筑结构的稳定性,施工单位需要明确水利水电建筑工程施工中混凝土裂缝引发原因,提出针对性防治措施,提高水利水电建筑工程施工质量。
2 水利水电建筑工程施工中混凝土裂缝的诱因
2.1 温差过大。温差过大会直接引发水利水电建筑工程施工中混凝土裂缝,在混凝土施工过程中,如果结构内外温差比较大,将会引发混凝土裂缝。混凝土施工阶段,水泥是重要的原材料,水泥性质比较特殊,遇水会出现发热反应,不利于及时散发混凝土内部的热度,内外温差因此被拉大,再加上混凝土具有热胀冷缩特征,如果内外应力过大,混凝土强度无法承受内外应力,因此引发混凝土裂缝。……
