Aiming at the low natural moisture content of natural wide graded gravel anti-seepage soil material in 300 m level high core wall rockfill dam, field contrast test between the process of “belt conveyor filling water + stacker heap + bin stuffy material” and the process of “layered paving + pipe network water + bin stuffy material” was carried out to verify the rationality and feasibility of the relevant filling water process. The test results show that the combination process of belt conveyor with water is superior to the pipe network stratified water process, mainly manifested that the belt conveyor automatic water system can achieve real-time, efficient and accurate automatic water filling soil; After water replenishment, the soil material is transported by the belt and piled by the stacker, which can realize automatic and uniform piling. After adding water to soil material, the moisture content inside the soil material is basically stable during 3-4 days of smother, and the time required for smother is short. This paper also put forward the improvement measures of water filling process of belt conveyor. The improved process of "water filling of belt conveyor + stoker + silo boring" can provide reference for soil water content adjustment of similar earth-rock dam.

针对某300 m级特高土质心墙堆石坝的天然宽级配砾石防渗土料存在“天然含水率低”的特点,进行了“皮带机加水+堆料机堆料+料仓闷料”工艺和“分层摊铺+管网加水+料仓闷料”工艺的现场对比试验,验证相关加水工艺的合理性、可行性。试验结果表明,皮带机加水工艺较管网分层加水工艺具有优势,主要表现在皮带机自动化加水系统能实时、高效、精准地实现土料自动化加水;补水后的土料经过皮带运输由堆料机堆料,可实现自动化均匀堆料;土料加水完毕,闷制3~4 d后内部含水率基本稳定,闷料所需时间短;并提出了皮带机加水工艺的改进措施,改进后的“皮带机加水+堆料机堆料+料仓闷料”工艺可为类似土石坝的土料含水率调整提供参考。

针对某300 m级特高土质心墙堆石坝的天然宽级配砾石防渗土料存在“天然含水率低”的特点,进行了“皮带机加水+堆料机堆料+料仓闷料”工艺和“分层摊铺+管网加水+料仓闷料”工艺的现场对比试验,验证相关加水工艺的合理性、可行性。试验结果表明,皮带机加水工艺较管网分层加水工艺具有优势,主要表现在皮带机自动化加水系统能实时、高效、精准地实现土料自动化加水;补水后的土料经过皮带运输由堆料机堆料,可实现自动化均匀堆料;土料加水完毕,闷制3~4 d后内部含水率基本稳定,闷料所需时间短;并提出了皮带机加水工艺的改进措施,改进后的“皮带机加水+堆料机堆料+料仓闷料”工艺可为类似土石坝的土料含水率调整提供参考。

Aiming at the low natural moisture content of natural wide graded gravel anti-seepage soil material in 300 m level high core wall rockfill dam, field contrast test between the process of “belt conveyor filling water + stacker heap + bin stuffy material” and the process of “layered paving + pipe network water + bin stuffy material” was carried out to verify the rationality and feasibility of the relevant filling water process. The test results show that the combination process of belt conveyor with water is superior to the pipe network stratified water process, mainly manifested that the belt conveyor automatic water system can achieve real-time, efficient and accurate automatic water filling soil; After water replenishment, the soil material is transported by the belt and piled by the stacker, which can realize automatic and uniform piling. After adding water to soil material, the moisture content inside the soil material is basically stable during 3-4 days of smother, and the time required for smother is short. This paper also put forward the improvement measures of water filling process of belt conveyor. The improved process of "water filling of belt conveyor + stoker + silo boring" can provide reference for soil water content adjustment of similar earth-rock dam.
