新型钻探工具在河道勘察中的应用

Application of a New Drilling Tool in River Survey

随着城市化进程的加速,城市中河道污染、淤积、水质差等问题日益严峻。近些年很多城市进行了大规模的河道清淤治理工程,在一些中小型河道清淤清障治理工程勘察中由于存在河道较窄、河水较浅、河道底部淤泥性质较差等问题,导致在河道底部水上作业难度较大。本文结合满堂河生态环境提升改造治理工程,提出一种新型的钻探工具,进行河道底部淤泥的勘探,结合传统的钻机进行护岸等配套工程的勘探工作,很好地解决了河道综合治理的勘察工作,为以后中小型河道清淤工程勘察提供参考。

With the acceleration of urbanization,the problems of river pollution,siltation and poor water quality in cities are becoming more and more serious.In recent years,many cities have carried out large-scale river dredging and control projects.In the survey of some small and medium-sized river dredging and control projects,it is difficult to operate on the water at the bottom of the river due to the problems such as narrow river,shallow river and poor sludge properties at the bottom of the river.Now a new drilling tool is proposed,which is mainly used for the exploration of silt at the bottom of the river.Combined with the traditional drilling rig,it is used for the exploration of bank protection and other supporting projects,which well solves the investigation work of comprehensive treatment of the river.Combined with the ecological environment improvement and treatment project of Mantang River,this new drilling tool is introduced in detail,which provides a reference for the future dredging engineering investigation of small and medium-sized rivers.
