土地平整工程土地平整工程：根据土地开发整理标准(TDTlOU-IOI3/22000)、土地开发整理项目规划设计规范(TD-TlOI2-2000)和重庆市土地整治工程建设标准(2015)等，结合项目区自然条件和地形条件及农民耕作习惯、农业种植品种结构等实际情况进行土地平整工程。确定本项目需达到的技术要求为：中低山槽谷区域，梯田化率不低于70%,田面坡度1(但项目区由于本身土层较薄及坡度较大，部分坡地区域整治后田面坡度设计为12°o坡面台面宽度N3m,旱地耕作层厚度N25cm,水田耕作层厚度N20cm,有效土层平均厚度N50cm,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%°(2)灌溉与排水工程根据灌溉与排水工程设计规范(GB50288-1999)、土地开发整理项目规划设计规范(TD/T1012-2000)、节水灌溉工程技术规范(GB/T50363-2006)、微灌工程技术规范(SL103-95)、农田灌溉水质标准(GB508292)、水利建设项目经济评价规范(SL72-94)和开发建设项目水土保持方案技术规范(SL204-98),结合项目区降雨分布、水土资源、作物种植结构、濯区规模及灌水方法等因素，确定灌溉标准按抗旱天数30天，灌溉保证率为75%；灌溉水利用系数为0.7,渠系水利用系数为0.75。根据高标准基本农田建设“集中连片、高产稳产”的建设原则，本项目要求满足灌溉设计保证率的农田面积比例不低于95%。(3)田间道路工程根据土地开发整理项目规划设计规范(TD/T1012-2000),田间道路设计应符合“与田、林、村、渠、沟等项目设施布局相协调，有利于田间生产的管理；注重保护生态环境，防止水土流失”等原则。根据公路工程技术标准(JTGBOl-2003),项目区内田间道参照四级公路标准设计。田间道设计标准按照重庆市土地开发整理工程建设标准(试行)(2007)设计要求，田间道路最大纵坡小于9%,田间道的平曲线半径一般应不小于15m。新建田间道路基填方在08m深度范围内，其压实度必须达到93%,且应分层碾压；填方在0.8m深度范围以上，其路基压实度必须达到90%以上，且应分层碾压。若压实度达不到要求，则必须经过12个雨季，使路基相对沉降稳定后，才能铺筑泥结碎石路面或硬化路面。生产路设计标准根据项目区生产生活需求，路面宽设计为20.8m,当生产路纵向坡度为大于6。时，表面应横向拉渡槽，防止路面溜滑，方便人畜行走，大于15。时应修建为梯步。（4）农田防护与生态环境保持工程按照重庆市土地开发整理工程建设标准（试行）（2007）设计要求，田防护与生态环境保持工程的布置在满足主体工程需要的前提下，应尽量做到土石方的挖填平衡和不产生弃渣，减少地面扰动，维护原生态系统。1.2 土地平整工程设计土地平整工程在整个土地整理工程中处于首要位置，是田块、渠道、道路规划设计的前提和基础，对合理灌排，节约用水，提高劳动生产率。发挥机械作业效率，以及改良土壤、保水、保土、保肥等方面，都有着重要的作用。1.2.1 台面重构项目区的旱地有两种情况，即已成台旱地和未成台旱地，已成台旱地为旱地田面已经形成一定台阶的旱地，而未成台旱地目前田块零碎、水土流失严重，本次需要将这部分未成台旱地进行坡改梯，经综合考虑投资、土层厚度、水土流失程度和耕作层质量等因素，规划对自然坡度为6。10。的旱地通过土地平整使台面坡度平均降到4,10。15。旱地的台面坡度平均降到68°,15。25。旱地的台面坡度平均降到降坡后为了防止水土流失的再次发生，统一对田块进行田坎设计。A、土地平整设计（1） 土地平整方式设计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：对垮塌摞荒杂草较多区域进行清杂；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，使梯地土层达到0.6m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。（2）台面重构中降坡平整土方量计算根据典型断面图确定单位面积挖（填）放量V关于H'（H÷h）即台面高差的函数关系:。一原地面坡度，(°)：B一降后地面坡度，(°)；H田坎高度，(m)；a一出坎坡度.一)：B-Hl面净宽，(m)：Bn-比坎占地宽度，(m：Bm四面毛宽，m)：Bx一田面斜宽,(m)；h一线段GE高度，(m)：Hz一台面高姜,(m)：a线段CD的长度：b一线段OC的长度：GK=H2说明：C、K为上下两坎中点v=SeoDXL12(gasin(-。)10000×tga×(tgtgXtiX×8sina×cos0×tga×(tg-tg)(tga-tg×H=1250×zg6yz×/tga=1250g'-'g“'表1.2.1-1台面重构整土方工程量计算表序号工程名称面积(hm2)表土剥离/回覆(m3)土方移动(m3)人工精细平土(hm2)1台面重构010.3065613337.150.30652台面重构-020.51951039571.450.51953台面重构-031.15322306.41268.521.15324台面重构-040.0537107.459.070.05375台面重构-051.07621521183.61.0766台面重构060.209418229.90.2097台面重构-071.55331061708.31.5538台面重构-080.67931358.6747.230.67939台面重构-090.3372674.4370.920.337210台面重构-100.2259451.8248.490.225911台面重构-110.97611952.21073.710.976112台面重构-121.40342806.81543.741.403413台面重构-130.74431488.6818.730.744314台面重构/40.94431888.61038.730.944315台面重构150.1138227.6125.180.113816台面重构-160.54911098.2604.010.549117台面重构-170.1941388.2213.510.194118台面重构-180.0781156.285.910.078119台面重构-190.50621012.4556.820.506220台面重构-200.2099419.8230.890.209921台面重构-212.28745742515.72.28722台面重构220.66011320.2726.110.660123台面重构232.65295305.82918.192.652924台面重构-240.1513302.6166.430.151325台面重构-250.54411088.2598.510.544126台面重构-262.96175923.43257.872.961727台面重构-270.77861557.2856.460.778628台面重构-280.0581116.263.910.058129台面重构-290.041683.245.760.041630台面重构-300.2518503.6276.980.251831台面重构-310.2142428.4235.620.214232台面重构-320.149298163.90.14933台面重构-331.10722141217.71.10734台面重构-340.91371827.41005.070.913735台面重构-350.88321766.4971.520.883236台面重构-360.97121942.41068.320.971237台面重构-370.62931258.6692.230.629338台面重构-380.1253250.6137.830.125339台面重构.392.15764315.22373.362.157640台面重构-400.56901138625.90.56941台面重构-410.4497899.4494.670.4497合计30.3896077833427.930.3891.2.2梯田整治a、田块归并工程设计对项目区零散存在的、田面高差在20Cm左右的田块实施田块归并。1）表土剥离/回填：为保护耕作层不被破坏，对整治区域进行表土剥离，剥离厚度不低于0.1m,剥离的表土堆放在周边整治地块内，作为表土回覆。（推运距离30-40m）o2）挖高填低：将挖方区域的土推运至填方区域（推运距离3040m）,使合并后田块内的田面平整度基本一致；各改造水田区域的挖填平衡计算见表；3）重构犁底层：在深层土方移动过程中会破坏原有地块土壤底层结构，因此在完成上一步工序后，需对平整的深层土进行压实，通过机械碾压原土,中间间隔润土，共碾压2次，特别是填方区域应是碾压的重点，压实后的犁底层土壤容重控制在1.82.0gcm3之间；4）新建田坎：田坎采用粘土人工夯实，顶宽设计为0.4m,内坡比1：0.5o外坡比根据田坎高度不同分别设置。高度低于Im（不含Im）的田坎外坡比为1:0.5,高度小于1.5m不含1.5m）外坡比为1:0.75,高度大于1.5m的田坎外坡比为l:lo另根据实际情况每条田坎设置1-2处放水口，放水口尺寸为0.4mX0.3mo放水口是为了保障旱地改成水田后、相邻田块之间能够水系互通，同时为保障田坎上部行人而综合考虑设计的。放水口采用土质夯实，在搭田坎时对放水口进行夯筑。5）机械翻耕、耙田：田块土坎夯筑好后，通过灌溉渠将水引到田块内，浸润土壤，采用旋耕机进行翻耕1次和耙田3次，可以恢复土壤耕层结构、提高土爆蓄水保墙（指土壤适合种子发芽和作物生长的湿度）能力、消灭部分杂草、减少病虫害、平整地表以及提高农业机械化作业标准，在达到要求的情况下相比人工、畜力犁耙田更经济；表122-1梯田整治工程量表序号工程名称面积(hm2)表土剥离/回覆(m3)土方移动(m3)犁底层重构(hm2)泡田打浆(hm2)1梯田整治-011.71592573.852402.261.71591.71592梯田整治-020.75011125.151050.140.75010.75013梯田整治-032.57583863.736()6.122.57582.57584梯田整治-040.0793118.95111.020.07930.07935梯田整治-050.2733409.95382.620.27330.27336梯田整治-060.1045156.75146.30.10450.10457梯田整治-070.3699554.85517.86036990.36998梯田整治-089.109813664.712753.729.10989.10989梯田整治-094.61826927.36465.484.61824.618210梯田整治01.19271789.051669.781.19271.192711梯田整治-110.4419662.85618.660.44190.441912梯田整治-122.61533922.953661.422.61532.615313梯田整治“32.63893958.353694.462.63892.638914梯田整治-142.80924213.83932.882.80922.809215梯田整治54.64786971.76506.924.64784.647816梯田整治-1612.662318993.4517727.2212.662312.662317梯田整治711.337117005.6515871.9411.337111.337118梯田整治-180.6311946.65883.540.63110.631119梯田整治-191.7632644.52468.21.7631.76320梯田整治-201.62224332270.81.6221.62221梯田整治-2116.399724599.5522959.5816.399716.399722梯田整治-220.73091096.351023.260.73090.730923梯田整治-230.4443666.45622.020.44430.444324梯田整治-2412.829619244.417961.4412.829612.829625梯田整治252.27573413.553185.982.27572.275726梯田整治-2610.22915343.514320.610.22910.22927梯田整治-270.80851212.751131.90.80850.808528梯田整治-280.1163174.45162.820.11630.116329梯田整治290.5401810.15756.140.54010.54013()梯田整治-300.4747712.05664.580.47470.474731梯田整治-312.02493037.352834.862.02492.024932梯田整治-320.8951342.512530.8950.895序号工程名称面积(hm2)表土剥离/回覆(m3)土方移动(m3)犁底层重构(hm2)泡田打浆(hm2)33梯田整治-334.67797016.856549.064.67794.677934梯田整治-340.3991598.65558.74039910.399135梯田整治-351.40842112.61971.761.40841.408436梯田整治-361.50852262.752111.91.50851.508537梯田整治-370.95691435.351339.660.95690.956938梯田整治3810.7981619715117.210.79810.79839梯田整治-395.68288524.27955.925.68285.682840梯田整治-403.41565123.44781.843.41563.415641梯田整治-413.47215208.154860.943.47213.472142梯田整治-422.13319529822.132.1343梯田整治-432.27113406.653179.542.27112.271144梯田整治-440.87641314.61226.960.87640.876445梯田整治-453.48815232.154883.343.48813.488146梯田整治-463.26094891.354565.263.26093.260947梯田整治-470.4158623.7582.120.41580.415848梯田整治-480.3625543.75507.50.36250.362549梯田整治-490.4748712.2664.720.47480.4748合计155.3257232988.55217455.98155.3257155.3257表L25梯田整治田坎修筑工程量统计表编号长度(m)顶宽(m)田坎夯筑量(m3编号长度(m)顶宽(m)田坎夯筑量(m3TK-I57.580.427.9TK-4363.250.430.7TK-IO47.270.422.9TK-430270.110.4131TK-I(X)43.830.421.3TK-431114.260.455.4TK-IO(X)25.70.412.5TK-4447.220.422.9TK-100l80.990.439.3TK-4566.910.432.5TK-100
