内容简介《DL/T 5199－2004水电水利混凝土防渗墙施工规范(英文版)》内容简介：This Standard is compiled according to the document issued byformer Ministry of Electricity Industry, referred to as ZKJ[1998] 28,named as "Notice on the Plan of Stipulating and Revising Standardsand Specifications of Electricity Industry in 1997 ".

The application of concrete cut-off wall in hydropower andwater resources industry has been started since the end of 1950s inChina, which has a history of more than 40 years. During itsapplication, three industrial specifications has been stipulated byhydropower and water conservancy industry and issued respectivelyin 1963, 1979 and 1996. These three specifications immediatelyconcluded the achievements made during the development ofconcrete cut-off wall technique, and had played an important role inguiding the construction of concrete cut-off wall in our nation'shydropower development, promoting the application of newtechnique, new material and new technologies, and guaranteeing thequality of project.

A tremendous progress has been made in recent years in ournation's cut-off wall technique. Many new experiences had beenaccumulated, especially in our nation's key project such as ThreeGorges Project, Xiaolangdi Project, etc.. This Standard is compliedby summarizing the new technique in our nation's cut-off wallconstruction practice and also combining the experiences fromoverseas projects.

7.0.1The axis and top elevation of the cut-off wall shall becontrolled by survey benchmarks according to design requirements.

7.0.9Determination of the trench length shall consider the factors,such as the engineering geological and hydrogeological conditions,construction location, trenching method, capability of equipment,duration of trenching, the supply of wall material, preformed holes inthe wall, the layout of tremie pipes and the plan shape of the wall.

The short trench may be adopted for closure trench, andarranged at location where the depth is relatively shallow and theconditions are relatively good.

7.0.3Trenches may be constructed by stages and enough safetyspacing shall be maintained between contiguous trenches that areconstructed simultaneously.7.0.4Trenching equipment and method can be selected accordingto the strata, the structural type of wall and the capability ofequipment, a combination of different equipment can be adoptedwhen necessary. The trenching methods are as follows: trenching byconcussion and split, trenching by drilling and grabbing, trenching bygrabbing, trenching by cutting, etc.
