Description
Technical field
The present invention relates to Construction of Rolled Concrete Dam quality control method in a kind of hydraulic engineering.Particularly relate to a kind of grinding concrete construction Coating combination time method for real-time monitoring.
Background technology
Roller compacted concrete is a kind of concrete of dry poor-water mud, and use portland cement, flyash, water, additive, sand become the dry concrete without slump with the coarse aggregate mixing of step control.Compared to normal concrete, roller compacted concrete has admixed a large amount of flyash, reduces the use amount of cement, thus reduces hydration heat, is conducive to dam temperature and controls.In work progress, RCCD adopts the transport identical with rock fill dam construction and paving equipment, closely knit with vibrating roller press layered rolling, can carry out streamlined, large area sequential production, improve concrete construction intensity, shortens the construction period.But due in roller compacted concrete, cement content is lower, adopts layered rolling simultaneously, therefore need binding time between key-course, to ensure bond quality between concrete layer.
The RCCD Coating combination time comprises the interlayer cover time, rolls band activity duration and time interval between layers.Incorporation engineering is on-the-spot actual, interlayer interval may be defined as lower base layer concrete from first time close a position play upper base layer concrete close a position complete till last and will control within the interlayer cover time; Roll band operation may be defined as every layer concrete from first time close a position play roll complete till last and will control rolling within the band activity duration; Interlayer interval may be defined as lower base layer concrete from first time close a position play upper base layer concrete roll complete till last and will control within time interval between layers.The Coating combination time is monitored in real time to be mainly and prevents from occurring cold seam between concrete rolling layers, and then the necessary means ensureing grinding concrete construction quality and Coating combination quality thereof and take.
The current research for roller compacted concrete interlayer bond quality control aspect focuses mostly in concrete raw material and proportioning test research, and Jiang Rongmei, Wang Shuyin are studied the presetting period extending concrete mix efficient retarding and water reducing agent; Long Zhihong, Zhang Shaowei, Chen Gang etc. set forth concrete mix control with raw material, describe the importance of raw material quality for concrete mix quality; Xie Yanhui, Wu Xu, Long Zhihong, Wei Hua, Li Shengfu etc. distribute rationally concrete mix and analyze, and have set forth the importance that concrete match ratio is compared to concrete mix quality; Long Zhihong, Zhang Shaowei highlight the material impact of MIXING SYSTEM CONTROLLED BY for roller compacted concrete quality, and cause the impact on Coating combination quality thus.Xie Yanhui, Chen Gang etc. have carried out certain research to the process of putting in storage in face, pouring construction storehouse to the impact of Coating combination quality on concrete production, they propose transportation to dam affects concrete quality, and Transport Machinery is cleaned, discharge process drop control etc., may cause aggregate separation case to be analyzed.Long Zhihong, Wei Hua, Zhang Shaowei discuss Roller Compacted Concrete Dam layer surfaces construction technology, for practice of construction provides guidance; Zhou Yihong, Xie Yanhui, Wu Xu, Chen Gang etc. are studied for rolling layers time interval between layers, and proposition will ensure that time interval between layers will complete within the concrete initial set time, otherwise need rise layer to process according to temperature rise layer the latter is cold; Therefore, Wei Hua, Wang Yingchun rise layer, temperature rise layer and cold life flat construction technique be studied the rolling layers heat under different time interval between layers; Wu Xu, Zhang Shaowei, Chen Gang etc. have studied varying environment, face, storehouse microclimate to the impact of Construction of Rolled Concrete Dam and construction method.Chen Gang carries out mending to construction position not up to standard and to grind and the construction technology of vibrating is studied, thus ensures, on a large scale in construction operation situation, local to be leaked to stones roller, owed the construction technology in stone roller region.
To sum up, although extensive for roller compacted concrete interlayer connexus quantifier elimination at present, but focus mostly in concrete raw material control and macro qualitative analysis control device, and close a position after putting in storage for roller compacted concrete, roller compaction process meticulous, real-time monitoring then not yet relates to, current roller compacted concrete interlayer binding time controls the other observation of standing of the main supervisor of dependence, obtain roughly heat and rise the layer time, the pedestrian that goes forward side by side exceedes Coating combination time controling standard for judging whether, the continuous extensive management of this mode, also there is the situation that face, part storehouse error in data is even omitted, control to bring larger hidden danger to roller compacted concrete interlayer bond quality.
