锯槽成墙法在蛤蟆通水库防渗中的应用

Groove-Sawing Technigue for Building Cut-off Wall and Its Application at Hamatong Reservoir

锯槽成墙法是一种建造地下截水墙的新技术．本文主要介绍应用锯槽成墙法在蛤蟆通水库建造地下防渗墙的施工工艺．实践证明，采用该技术建造的地下防渗墙具有墙体连续、厚度均匀、适应变形能力强、施工效率高及成本低等优点．

This paper mainly introduces the construction process of applying the grooving wall construction method in building the underqround antiseeping wall in Hamatong Reservoir. The construction has proved that the underground antiseeping wall built with this technical process has the advantages ot successive wall body,even thichness,strong adaptability to the deforma-tion,high construction efficiency, low production cost etc. This technique has been studied and developed by the Northeast Geotechnical Co. and has gained the national patent right. The birth of this new technique has opened up a new way and vast prospects for the construction of the un-derground successive wall.
