9、并、台面重构、旱改水、梯田改造、边角地整治、开发零星未利用非耕地、低效园林地整治等工程。1.1.1 台面重构本项目土地平整采用局部平整方式，不搞统一化，应根据地形、面积、空间结构特点将项目区划分成若干坡度土地平整单元，单元内土地平整的填挖方尽可能限制在本单元内部，追求单元内土地平整的统一化；挖高填低，尽可能挖填平衡，相邻单元之间平整后的高差作为相邻梯田的高差。土地平整施工分四个程序：即坡改梯前将原坡耕地较肥沃的表土（厚0.2m）先剥离，待平整后回填作梯田表土，以利耕作，运距控制在10-2Om之内；未成台旱地田土移动、挖高填低，以实现梯地平整要求，土方移动运距控制在30-4Om之内；下层深翻，使
10、梯地土层达到06m厚的要求；表土回填，即将原剥离的表土均匀覆在平整后的田块表面，确保熟化表土的回填率达90%以上。土地平整中降坡平整土方量计算：对于项目区的台面重构土方移动工程，设计选取项目区具有代表性的台面重构地块进行样方测算，测算加权平均后得出项目区平均土方移动工程量。表LlJ样方测量工程量表编号格田编号面积(m2)设计高程(m)机械除杂(m2)土方开挖移动(m3)表土剥离面积(m2)表土剥离V(m3)表土剥离场内转运田坎长度(m)方量(m3)台面重构021482.45502.183482.45112.2241.2348.254.825116.5821101498.9361101.0049

18、：将挖方区域的土推运至填方区域，使合并后田块内的田面平整度基本一致，根据实际测算平均挖填运距约为50米；4）田填修筑：新修田坎为土质田坎，采用生土分层夯实，迎水面采取泥浆”搭田边、糊田坎”的方式进行防渗处理，根据实际情况每条田坎设置1到3处放水口（土），修筑好的田坎具有囤水功能；5）犁底层夯实：在深层土方移动过程中（挖填大于0.2m的田块）会破坏原有犁底层结构，因此在完成第5步工序后，需对平整的深层土进行压实，压实后的犁底层土壤容重控制在1.82.0gcm3之间；6）机械造浆：待犁底层夯实后，在田块内进行机械造浆。采用的施工方法为机械造浆，蓄水深度20cm,蓄水后使田块表层土充分浸泡，浸泡时间
19、每次不少于5天，最后对充分浸泡后的田块进行翻耕打浆，翻耕采用人工翻耕，翻耕深度控制在20Cm以内，翻耕过程中使表层土得到充分搅动，保证田面蓄水深度基本一致；7）表土回填：将剥离的表土回填至合并后的田块，均匀摊铺；8）人工细部平整：在犁底层夯实后，田块内平整度不能满足设计要求，因此需要通过人工进行细部平整，保证田面的平整度达到3cm;9）地力培肥。1.1.2.2质量检测要求和验收标准表L1.2-1土地平整验收技术指标技术指标基本具备型精加整治型全面整治型有效土层厚度（Cm）505050田面高差（cm）333新作层厚度（cm）15犁底层月度（Cm）10田境高度（Cm）151515田间渗漏强度（mm
