Because robots are good development of the technology makes a good optimization of productive capital, and robot shows this unique advantages, such as: has good compatibility, wide availability, hardware is complete, and programming that can be mastered in a short time, so in the context of ind
6、ustrial PLC applications became ubiquitous. Manipulator in many developed country agriculture and industry has been applied, such as the use of mechanical harvesting large areas of farmland, repeated operations on the high-speed line that uses a robotic arm, and so on. Today, the high level of autom

13、侧，科技街南侧。由于基坑深度为0.000以下10.5米，因此基坑开挖需要进行基坑的支护，基坑支护方案采用深层搅拌桩止水帷幕加土钉墙支护。止水帷幕采用深层搅拌水泥浆喷桩进行处理。帷幕桩设计桩径500mm，两排水泥搅拌桩呈三角形布置，排间距为350，桩间距为300，相互搭接100，采用湿法施工，桩的垂直度0.5%，水泥搅拌桩采用P.S32.5水泥，桩身强度R281.5MP。桩深为自然地面下17。水泥掺入量为不少于60kg/m。基坑支护采用预应力锚索加土钉墙支护，土钉长度9-13m，孔径100mm，土钉与水平夹角10-15。竖向排距和水平间距均为1.3m。注浆采用水灰比为0.5的纯水泥浆，应采用二次
14、常压注浆，注浆量不小于30Kg。第三排为预应力锚索，预应力锁定值为100KN。第4-7排土钉，可能因在地下水位以下不能成孔，可改为40（3mm厚）钢管打入式管钉，土钉长度相应增加1m，钢管采用普通钢管，沿管壁每300mm开一双出浆孔，出浆孔孔径6-8mm管钉外端部2m范围不设孔眼，出浆孔处焊小角钢或短钢筋护孔。降水井直径600mm，井深至-16m，共设降水井18口。基坑周围设置水位观测井（兼作回灌井），定时监测地下水位变化，井径600mm，井深至-16m。本工程0.000相当于绝对标高778.450。二、工程地质概况拟建场地标高为777.76-778.63，地貌单元属于汾河东岸级阶地，地层基本
