在堤防施工中,经常用到边坡放样的坡度尺。常用坡度尺是木制的,尺寸较大,不便携带,坡度变化范围小、精度低、易损坏。笔者在１９９９年松花江堤防施工中,根据实际使用情况,设计制作了一种铝合金坡度尺,长１２米、高０４米,可以拆卸、伸缩,便于携带,精确度高,是一种实用的堤防施 In embankment construction, often use the slope to set out the slope of feet. Common slope scale is wooden, large size, inconvenient to carry, small gradient range, low accuracy, easy to damage. In 1999, the Songhua River embankment construction, according to the actual use of the situation, designed a slope of aluminum alloy, 12 meters long, 04 meters high, can be demolished, telescopic, easy to carry, high accuracy, is a practical Dike facilities
