龙门式布料机在袁冲暗涵工程中的深入应用
|
摘要
龙门式布料机具有轨道式行走、连续作业、成本低廉的优势,在南水北调箱涵、倒虹吸工程中得到充分利用,但鄂北调水暗涵工程具有地面起伏大、截面多样的特点。从袁冲暗涵工程实例出发,进行多项研究和应用,采取活动溜槽、坡面溜槽、固定桁架溜槽配合龙门布料机和铰接变幅龙门布料机等方式解决了不同坡面高度受料问题;采取桁架伸缩、调节门轨宽度的方式解决了布料机满足不同截面暗涵的使用问题;采用鱼刺缓冲串筒减小了高落差下的混凝土离析。以上应用均取得了较好效果,可供同类型工程参考。
Gantry distributing machine has the advantages of rail-type walking,continuous operation and low cost. It has been fully utilized in the box culvert and inverted siphon work of south-north water diversion project. However,the dark culvert project of Hubei north water diversion project has the characteristics of large ground fluctuation and diversified sections. Yuanchong dark culvert engineering example shows that a number of researches and applications have been done.Activity chute,slope chute chute and fixed truss chute are combined with gantry distributing machine and articulated luffing gantry distributing machine,etc. for solving the problem of material receiving at different slope heights. Truss scale and door track adjustment are adopted for solving the problem that the distributing machine meets different section dark culverts.Barb string buffer tube is adopted for reducing concrete segregation under high drop. The above applications have achieved good results,which can be used as reference for similar projects.
