At present，Railway Construction Heavy IndustryLSJA series of chain-knife diaphragm wall equipment has been continuously constructed for four months in the key embankment reinforcement project of Dongting Lake.，The construction volume is up to 80000㎡，Maximum daily footage of transverse wall formation: 60m/d，The permeability coefficient of the wall can reach 1×10e-6cm/sAnd above，The construction efficiency and anti-seepage reinforcement quality have been unanimously recognized by customers.。

The key embankment reinforcement project of Dongting Lake has a long and narrow construction site.、The construction area is wide and scattered.。Railway Construction Heavy IndustryLSJ60 Maximum wall-forming depth of chain-knife continuous wall equipment 60m，Wall width 500-900mm，Outer width of two tracks 4.8m，Adapt to greater depthTRDEngineering construction；LSJMaximum wall-forming depth of 35 series chain knife type continuous wall equipment 35m，Wall width 500-1200mm，Outer width of two tracks 3-4m，Can better adapt to 6mConstruction of narrow dike surface。LSJSeries chain knife type continuous wall equipment has stable and reliable performance、And that construction efficiency is high、The transition speed is fast、And that occupy area is small、Strong ability to extricate oneself from difficulties、High degree of informatization，And can well meet that requirement of long-distance dike reinforcement construction and remote informatization supervision.，Solve a wide range of customersTRDSafety during fleet construction、Problems with high quality requirements and difficult supervision，Make the construction progress、The quality is guaranteed。

China Railway Construction Heavy Industry will continue to adhere to customer demand-oriented，Carry out independent innovation，Vigorously develop informatization、Intelligent construction equipment，Build flood control safety for the country、Ecological security、Water conservancy projects contributing to water supply safety。
