渣场拦渣防洪系统设计

Design of slag and flood control system

首先对灰渣场的环境、容量、作用、工程内容进行了简单的说明,其次对拦渣坝的结构做法进行了详细的设计,坝体为均质坝,主体部分由粘土压实砌筑,坝上游坡面防渗体采取土工膜防渗,坝外采取浆砌石护坡,并详细说明了地基处理、坝面排水、护坡、坝顶道路的做法,最后对防洪系统进行了系统的阐述,防洪系统截洪沟结构均采用MU30浆砌块砌筑,并按照场区情况对排水沟、场底导排干管、渗滤液收集池、竖井进行详细的设计。

Firstly,the environment,capacity,function and engineering content of the ash yard are explained in this paper.Secondly,the structure of the dam is designed in detail.The dam body is a homogeneous dam,the main part is compacted by clay,the impermeable surface of the upper reaches of the dam adopts geotechnical membrane impermeability,and the outside of the dam adopts slurry stone protection.The practices of foundation treatment,dam surface drainage,slope protection and dam top roads are explained in detail.Finally,the flood control system is described systematically.The structure of flood control system is made of MU30 mortar block masonry,and the drainage ditch,drainage dry pipe,leachate collection pool,and shaft are designed in detail according to the situation of the field area.
