深基坑工程检查验收 深基坑工程检查验收提要：预应力锚索最大检验荷载为锚索设计轴向拉力的倍，且不应超过锚筋Afptk的倍。预应力锚索验收合格标准为：（1）检验曲线的总弹性位移应 深基坑工程检查验收 1常规材料检测，施工用的原材料如水泥、钢筋、砂石等。 2为确定土钉与土体之间的抗剪强度及有关施工参数，应进行基本抗拔试验。基本试验数量不宜少于三根，如果地层复杂，可适当增加试验数量。 3土钉应按相关规范规定进行抗拔力验收试验，其注浆体强度应按相关规范规定进行检测。 4土钉抗拔力设计值在人工填土中为4kN/m；在其他土层中取8kN/m。 5喷射砼强度检验，试块按每500m2取一组，每组试块不得少于三个。 6坡面喷射混凝土厚度应采用钻孔检测，钻孔数宜每100㎡墙面积一组，每组不应少于3点； 7钢筋土钉及锚索注浆体强度检验试块数量每30根不少于一组，每组试块数量为3块，水泥净浆为6块；土钉及锚索抗拔力检验应在锚固体强度达到设计强度的80％以后进行；检验数量土钉不宜少于总数的1%且不少于3根，锚索取总数的5%且不少于3根。如果地层复杂，可适当增加试验数量。 8土钉验收合格标准为：土钉抗拔力平均值应大于设计抗拔力，抗拔力最小值应大于设计抗拔力的倍。 9预应力锚索最大检验荷载为锚索设计轴向拉力的倍，且不应超过锚筋Afptk的倍。预应力锚索验收合格标准为：（1）检验曲线的总弹性位移应超过自由段长度理论弹性伸长的80%，且不小于自由段长度与1/2锚固段长度之和理论弹性伸长值；（2）在最大检验荷载作用下，锚头位移趋于稳定。 10混凝土灌注桩应采用低应变动测法检测桩身完整性，低应变动测法检测数量不宜少于总桩数的10%，且不得少于5根。 11旋喷桩帷幕施工质量主要进行开挖后渗漏检查，有明显渗漏处应进行注浆堵漏。 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 stud
