工程建设标准根据土地整治项目规划设计规范（DB50Tl（H5-2020）、重庆市土地整治工程建设标准（试行）（2015）、土地整治项目工程量计算规则（TD/T1039-2013）、重庆市市级土地整治项目规划设计、单体及预算审查要点（试用稿）和当地实际特点，项目区工程建设标准如下：土地平整工程：梯田化率不低于80%,耕作区集中连片规模N50亩，田面坡度36。,坡面台面宽度6m,耕作层厚度20cm,有效土层厚度50cm,适宜小、微型农机作业的耕地面积占项目区耕地面积的比例70%.灌溉与排水工程：灌溉标准按抗旱天数为30天，水田灌溉保证率及0%,农田有效灌溉面积比例不低于85%；灌溉水利用系数为0.75,渠系水利用系数0.85,排涝设计标准按10年一遇设计；水田区暴雨历时l-3d,3-5d排至作物耐淹水深，旱地暴雨历时l-3d,l-3d排至田面无积水，农田有效排水面积比例不低于95%。田间道路工程：为满足项目区机械化耕作和农民生产生活出行需要，田间道路面宽度规划为3.0m,路面采用C20舲现浇；生产大路路面宽度为2.0m,采用C20建现浇。规划实施后的田间道路通达度达到80%以上。1.2 土地平整工程1.2.1 田块归并项目区田块归并，将相邻的不同台面的小田块归并为大田块，归并零星地块，整理田边地角闲置地。田块大小根据田块实际高差等情况，田块面积2-20亩不等。田块归并选择区域地势较为平坦，对每个区域均建设为条田，平整后每个条田处于同一高程面，按照设计情况设计高程，田面允许相对高差为土3cm,针对产业发展和田块实际地形，主要工程措施挖高填低，修建田坎。1）表土剥离工程量表土剥离工程量按下式进行计算：V=SXh式中：V表土剥离方量，m3;S一面积，m2；h一表土剥离的厚度，0.2m；2) 土方移动工程量水田整理区的土方移动量为每一块拟整理归并的水田区域的土方移动量之和。本方案采用散点法进行土方移动量的计算，计算原理为：根据同一个归并区域内部各零碎田块间挖填方平衡的原则，设同一归并区域内零碎田块1、田块2、田块n的土方移动量为TLT2、Tn(若T>0则为挖方,T<0则为填方),则Tl+T2+Tn=O0为求得区域内各田块的土方移动量Tn,设各田块的面积分别为SI、S2、Sn,各田块的高程分别为HI、H2、Hn,平整后的田面高程为Ha,则：Tl=SlX(Hl-Ha);T2=S2×(H2-Ha);Tn=SnX(Hn-Ha);平整前各田块的面积S和高程H可根据实测地形图测算所得，平整后的田面高程可按下式计算：SiX%+S2X/2+SXHa=S1+S2+S31根据以上计算方法，即可求得某一个田块内各零碎田块的土方移动量为TkT2、Tn,同时得到这个整理区域的土方移动量：Rl+Il÷十区I1 =2根据以上的计算原理，对每一块拟规划的区域进行计算，最终得出本项目水田整理的土方开挖量。田块归并时，相邻归并田块挖填高度在0.2m以内的，不进行表土剥离设计，直接进行挖高填低；挖填方高度大于0.2m的需进行犁底层重构，犁底层重构过程如下：将新建的田块平整后注水，注水后采用旋耕机进行第一次翻耕，翻耕后注水沉淀3-5天后进行第二次翻耕，第二次翻耕完后再沉淀35天再进行第三次翻耕，第三次翻耕完后再沉淀3-5天再进行第四次翻耕并人工修筑田坎；在施工时注意严格按照设计高程进行放线开挖和回填，做到挖填平衡。表
