新型埽工——笼埽在黄河控导工程中的应用

Application of a new type fascine - cage fascine to training works for Yellow River

介绍了新型埽工——笼埽的结构形式、施工方法,其优点为:(1)克服传统埽工施工工序复杂、速度慢、效率低的缺点;(2)笼埽可工厂化生产,减少现场作业工序和作业面后移;(3)充分利用大型施工机械进行大体积单个笼埽结合机械化施工,作埽速度快、强度高;(4)减少柳料用量,利于环境保护.结合在兰考蔡集控导工程水中进占工程中的应用,从施工准备、机械配合与人员安排及施工流程等方面对笼埽施工技术作进一步说明,并总结了施工注意事项.最后,进行了效益评价并提出了扩大技术应用范围和进行水槽实验的完善思路.

The structure and the construction method of a new type of fascine are introduced herein, of which the advantages are as the follows. (1) The shortages of the complicated construction process and low construction progress with low efficiency are o-vercome. (2)The fascine cage can be industrially made,so as to reduce the working procedure in site. (3)The heavy construction equipments can be used for the mechanical construction of the single large size fascine cage with high construction speed and intensity. (4) It is favorable to the environment protection as the amount of the fascine material being decreased. Base on the application to Caiji training works in Lankao county, the construction procedure consisting of the preparation and the construction combined with the mechanical equipment is further described for the technique, and then some key points necessary to be reminded during the construction are summarized as well. At last the benefit evaluation is made and an idea to enlarge the application with the water tank test is put forward.
