当渠堤外侧地面有相当长度（超过100m）上体不能利用（如苇塘、淤泥、树林等）时，只能用汽车从堤外上料场运上填筑，进行加高培厚，如图1：回l第境外运土加高培厚平面示意图外运土筑坝程序如下：l料场选择土料场尽量选择在所筑堤段的中间部位，以缩短间距，如与渠堤相隔一段树 When there is a considerable length (more than 100m) of upper body on the outside of the canal bank (such as reed ponds, silt, woods, etc.), it can only be filled by car from the loading area outside the embankment to increase the height of the embankment, as shown in Figure 1 l Outline of Plane for Earth Raising Plane of Embarkation Abroad Procedure of embankment for earth embankment is as follows: l Selection of material yard The soil material field should be selected as far as possible in the middle of the embankment section to shorten the distance, for example,
