小浪底大坝填筑机械化施工

Mechanized construction of the Xiaolangdi earth rockfill dam

小浪底工程堆石坝施工的主要特点是拦洪及度汛标准高、填筑方量大、工期短、填筑强度高。为实现高强度的施工 ,引进了先进、大容量、性能好的成套施工机械设备 ,施工中针对填筑工序作业特点合理地配置组合机械设备 ,实行科学的统一管理、调度、维护和保养 ,提高了每台机械设备的完好率、利用率和生产率。开工至今大坝填筑进度不断超前于合同计划目标 ,填筑强度高和不均匀系数低 ,填筑施工技术和水平已达国际先进水平 ,说明科学的施工管理加上成龙配套的。

The construction of Xiaolangdi rockfill dam is characterized by high standard of flood retaining and control,large quantity of dam filling,short construction period and high filling rate.To bring about high speed construction,advanced and complete set of construction mechanical equipment with large capacity and good performance are introduced.The mechanical equipment are rationally combined and disposed in consideration of operations of dam filling procedure,which are scientifically managed,dispatched and maintained in a unified way and thus the good condition rate,utilization rate and productivity of each piece of equipment are increased.From biginning up to date the dam filling progress always keeps high filling rate,low nonuniform rate and advance of the contractual schedule,and the construction technology and level have reached the international advanced level.This is owed to scientific construction management and excellent complete set of construction machinary.
