A WORKING METHOD FOR A PROTECTIVE STRUCTURE

摘要

The method constructs a simple protective structure against the slope of heaped earth. The method comprises the steps of: excavating and pouring concrete for foundation work to install concrete pipes and steel pipes to form a breast wall in front of the sloped earth; fastening the upper parts of the pipes together close to one another and steadying the lower parts by pouring concrete to them; securing anchor bolts in the earth to steady the pipes firm; filling earth in the space between the pipes and sloped ground; repeating prior steps to build stepwise breast walls against the sloped ground.
