Trench spoil pit should be placed away from the trench by at least 0.4 meter with a height of less than 1.5m.

6、在土質(zhì)松軟地帶挖溝、坑時(shí)應(yīng)按斜坡形開挖，坡度的大小應(yīng)根據(jù)土壤的性質(zhì)、濕度及坑深確定，宜符合下表的規(guī)定：

When trench in soft soil area, excavate a slope with its angle based on the nature, moisture of the soil and pit depth. The slope should meet the following requirements:

 

溝、坑的坡度表

Table of slope of trench and pit

 

 

7、挖水溝、坑及流沙溝、坑時(shí)應(yīng)采用防護(hù)板或沉箱等加固措施。

Digging ditches, pits and sandy ditch, pit, reinforcement measures like protection shield or caisson should be taken.

8、防護(hù)板的安裝或撤除應(yīng)有人監(jiān)護(hù)。嚴(yán)禁將防護(hù)板一次全部撤除。強(qiáng)流沙地帶不宜撤防護(hù)板。
