深基坑施工安全技术保障及措施 深基坑施工安全技术保障及措施提要：采用250*250H型钢实施围护桩，周边围令加固，并根据具体情况增设对角斜撑距离及数量，现场配备压密注浆机，对个别渗漏处进行止漏处理 源自建筑资料 深基坑施工安全技术保障及措施 ⑴、为提高深基坑围护的安全可靠性对拉森桩的入土深度，进行理论数据的计算，并对围护桩的强度及稳定性进行验证，确保深基坑施工的可靠性。 ⑵、沉设围护桩的施工中，严格按照沉桩规范施工，基坑四角必需采用角桩，最大程度的提高小齿口拉森桩防漏性能，保证下道工序顺利进行。 ⑶、采用250*250H型钢实施围护桩，周边围令加固，并根据具体情况增设对角斜撑距离及数量，现场配备压密注浆机，对个别渗漏处进行止漏处理，实现拉森桩围护项，技术参数达到规范要求。 ⑷、严格按照基坑施工规范实施每道工艺的施工，开挖坑土堆放至10m～15m（1倍桩长）以外，坑土堆放要平整最大程度的减小堆土对围护桩的侧压力，增强围护的安全系数，即时对坑内积水进行抽排。在对基层实施挖土时，挖土机械严格按照规范操作，最大程度的减小挖土机械单位受力面积，杜绝冲击荷载，对围护桩的破坏，确保基坑安全。 ⑸、建立严格的工序交接程序，制定科学、严谨、可行的施工计划，最大程度的调动施工群体的主观能动性，拟定合理的奖罚条律，坚持以人为本，安全第一的原则，加强协作意识，高度重视施工质量，如期完成施工任务。 源自建筑资料 Measures for the routine management of moral education in Middle SchoolsMethod of conventional management of moral education in middle schoolFirst, the guiding ideology:School moral education is an organic whole of the whole education work, always adhere to the school adhere to the moral education, education for this product, and actively promote the quality education, the school building efficient curriculum system of moral education, moral education, improve the sense of attraction and appeal, enhance the moral education work for through and timeliness. Teach everyone, service education and management education, and school moral education work must be with family education and community education closely together, to form a concerted pattern, and strive to create a good atmosphere for education, and to promote the all-round development of students, to establish a scientific moral education full of vigor the For long-term mechanism.Two, the goal of moral education:To guide the students to form the correct world outlook, outlook on life, values, to cultivate students unity and mutual assistance, honest and trustworthy, law-abiding, good quality, hard work, set a good XX students ideological quality, psychological quality and image quality.
