1、1 排水工程施工方案一、工程概况道路总体呈丁字形，道路东西段长496米，南北段长 195米，全长共 691 米。污水管道全长596米，雨水管道全长911米。二、施工要求（一）、排水工程：排水工程包括雨水及污水，雨水管采用承插式钢筋混凝土圆管，接口为承插式柔性接口。雨水口连接管由于覆土较浅均采用满包混凝土加固。雨水口连接管采用 D300管，坡度不小 1.0%。圆管规格为 D300 D1500之间多钟规格。污水管道采用双壁波纹管（环钢度8）管道基础采用砂垫层基础，管道连接采用承插式弹性密封橡胶圈，管道与检查井接口采用膨胀橡胶圈配套用件必须由管材生产厂配套供应。污水管有 300、400二种规格的双壁

2、波纹管，本工程排水管道数量较多、对工期影响较大，在施工时需引起足够的重视。（二）、工艺流程：测量放线沟槽开挖管道安装检查井的砌筑闭水实验沟槽回填。1、施工工艺流程：平整场地2 定位放线施出挖土灰线考虑放坡采用降水措施土方开挖土方运走地基处理测量槽底标高验槽结束施工2、沟槽以逆流方向进行开挖，使已铺设的下游管道先期投入使用，供后段工程的施工排水。3、根据施工设计图纸、现场地质情况及场地条件，测量人员在开挖前放出开挖边线（上口线和下口线），撒白灰线，上口四角打木桩，并标出开挖深度。机械应按上口线和下口线放坡开挖沟底，保留20cm的保护层。测量工应在开挖底面每35m设测点,严格按设计要求控制槽底标高

3、。4、沟槽开挖采用 1m3反铲挖掘机、人工配合的方法开挖。沟槽开挖深度均大于2m，采用大放坡开挖、放坡坡度为1：1。（见开挖沟槽断面图（一）一部挖掘机开挖无法满足要求，必须采取两台挖掘机传送文档编码:CK10A6H4Z4J2 HZ8I4K4B3X5 ZD7Q7O4V9C8文档编码:CK10A6H4Z4J2 HZ8I4K4B3X5 ZD7Q7O4V9C8文档编码:CK10A6H4Z4J2 HZ8I4K4B3X5 ZD7Q7O4V9C8文档编码:CK10A6H4Z4J2 HZ8I4K4B3X5 ZD7Q7O4V9C8文档编码:CK10A6H4Z4J2 HZ8I4K4B3X5 ZD7Q7O4V9C8

35、道，先由一人用棉纱绳吊住被安装管道的插口，另一人用长橇棒斜插入基础。并抵住该管端部中心位置的横挡板，然后用力将该管缓缓插入原管的承口预定位置；D500mm 管道可由 2 台 0.5 吨手拉葫芦将管材拉动就位。接口合拢时，管材两侧的手拉葫芦应同步拉动，使橡胶密封圈正确就位，不扭曲、不脱落。（八）、预防接口合拢时已排设管道轴线位置移动，需采用稳管措施。具体方法可在编织袋内灌满黄砂，封口后压在已排设管道的顶部，其数量视管径大小而异。管道接口后，应复核管道的高程和轴线使其符合要求。（九）、雨季施工防止管材漂浮措施。可先回填到管顶以上一倍管以上的高度。（十）、管道与检查井的衔接，采用中介层作法，即在管材

36、或管件与井壁相接部位的外表面预先用聚氯乙烯粘接剂、粗砂做成中介层然后用水泥砂浆砌入检查井的井壁内。中介层的长度与检查井厚度相同。直接与检查井连接的管段长度为5080cm，后面再连以不少于一根的长度不大于 2m的短管，然后再与上下游标准管长的管段连接。四、雨水钢筋砼承插管施工文档编码:CK10A6H4Z4J2 HZ8I4K4B3X5 ZD7Q7O4V9C8文档编码:CK10A6H4Z4J2 HZ8I4K4B3X5 ZD7Q7O4V9C8文档编码:CK10A6H4Z4J2 HZ8I4K4B3X5 ZD7Q7O4V9C8文档编码:CK10A6H4Z4J2 HZ8I4K4B3X5 ZD7Q7O4V9C

43、4V9C87（一）、地基处理：管沟开挖完毕，按规定对基底整平，并清除沟底杂物，如遇不良地质情况或承载力不符合设计要求应及时与甲方、设计、监理单位协商，根据实际情况分别采用重锤夯实，换填灰土、填筑碎石、排水、降低水位等方法处理。管基采用砂石基础，即采用粒径2.5mm 碎石或中粗砂，厚度为 100-200mm，经检查符合设计及有关规定要求后及时施工基础以封闭基坑。（二）、管道安装：管道敷设前应对沟槽进行检查，测量槽底高程和宽度，清除槽底杂物等。管节敷设应平顺、稳固，管底坡度不得出现反坡，管内不得有泥土、砂石等杂物。管材经过检查、修补后，运至沟边，按图纸要求排管，核对管节、管件位置无误后方可下管。安

44、管要求直顺，从下游排向上游，插口向下游，承口向上游。安管时，要求保证管道安装的线型直顺；在每个井段安装中，随时用水准仪测设管道安装的高程，确保流水面的高程准确。带承口的半节管排在检查井的进水方向，带插口的半节管排在检查井的出水方向。管节合拢采用手扳葫芦方法：手扳葫芦一端用钢丝绳与承口拉钩连接，另一端作为固定反力端，管节合拢时两只手扳葫芦应放置在管节水平直径处，拉钩勾在被合拢管节的承口壁，手扳葫芦反力端可用钢丝绳，卡扣等固定于临时方木，合拢时两只手扳葫芦应同步拉动，使管节合拢。管子承插就位，应进行下列检查：复核管节的高程（标高）和中心线。高程有误差时利用吊车系管点动找准；高时用特别小铲除去砂层，

45、低时塞入砂料并用小锺击实。检查承插口之间的间隙为 9mm15mm。接口处采用 O 形橡胶圈密封。之后对接口进行检查，检查承口插口的位置是否符合要求，用钢板尺伸入承插口间隙中文档编码:CK10A6H4Z4J2 HZ8I4K4B3X5 ZD7Q7O4V9C8文档编码:CK10A6H4Z4J2 HZ8I4K4B3X5 ZD7Q7O4V9C8文档编码:CK10A6H4Z4J2 HZ8I4K4B3X5 ZD7Q7O4V9C8文档编码:CK10A6H4Z4J2 HZ8I4K4B3X5 ZD7Q7O4V9C8文档编码:CK10A6H4Z4J2 HZ8I4K4B3X5 ZD7Q7O4V9C8文档编码:CK10
