Thus, for flood control in those periods, we should set up emergency handling system for weather forecast, ensuring construction quality and project progress. So the works in rainy seasons are as follows: 地基与基础工程、防水工程、钢筋工程、模板工程、混凝土工程、砌筑工程、装饰装修工程、机电安装工程、脚手架工程。Foundation works, water-proof works, reinforcement works, formwork, concrete works, masonry works, decoration works, mechanical and electrical works and scaffolding. 主要施工机械：塔吊、电焊机、切割机、砂浆搅拌机等。Main Equipment: tower crane, welding machine cutting machine and mortar mixer. 第7节 、雨季施工主要技术管理措施Chapter VII Main Technical Measures7.1 雨季施工管理7.1 Management in Rainy Season 7.1.1雨季施工前领导小组认真组织有关人员分析雨季施工生产计划，并在进入雨季前组织各单位进行工程全面检查，落实方案措施的实施情况，检查施工中存在的隐患。在进入雨季后定于每周四定期进行综合检查，雨季施工及防汛所需的各种材料、设备要在雨季施工前准备好。7.1.1 Construction scheme will be properly planned and arranged. Overall check will be performed for each construction unit and concrete measures will fully be taken on. Defects and risks should be fully inspected. Comprehensive check and inspection will be done every week on Thursday. All needy and urgent materials, tools and equipment should be fully prepared in advance. 7.1.2成立防汛领导小组，制定防汛计划和应急预案措施。7.1.2 Flood control leadership crew is set up and control plan and emergency measures are prepared. 7.1.3项目部执行夜间值班制度，夜间设专职的值班人员，保证昼夜有人值班并随时做好值班记录。夜间值班人员同时担任天气预报员，负责收听和收集有关部门的天气预报，并及时提供给项目部各有关部门和单位。7.1.3 On night shifts we arrange staffs on duty, ensuring 24-hour recording. Staffs on night shifts will also follow weather forecast and collect climate information, submit to leadership crew and inform each construction units.7.1.4应做好施工人员的雨季施工培训工作，进入雨季前，组织相关人员进行一次全面检查，检查施工现场的雨季施工及防汛的准备工作，主要包括临时设施、临电、机械设备、外装修用脚手架及屋面各楼层是否渗漏水。7.1.4 Training will be given to each construction staff. Before entering into rainy season, we arrange full and over inspection for temporary facility, temporary power, equipment and scaffolding for flood control and rain leakage. 7.1.5检查施工现场及生产生活基地的排水设施，疏通各种排水管道，清理排水口，保证雨天排水通畅。7.1.5 drainage facilities for the whole camping spots should be checked and inspected, ensuring each spot pipe line open, clean and smooth for rains running.7.1.6由于本工程的基础工程、主体结构工程及机电安装工程正好赶上雨季，应严格按方案要求做好各分项工程的施工，所有机电材料应进入室内仓库摆放，屋面的排水管应畅通并接入指定管网。7.1.6 Since rainy season encounters the main foundation work, structural works and mechanical and electrical works, we strictly make plans for each sub divisional work, make electrical material stay in storage house and make drainage pipes smooth and connected with appointed rain system. 7.2地基与基础工程7.2 Base and Foundation Works 7.2.1土方开挖7.2.1 Earthwork excavation土方开挖施工过程中，要保证降水工程的降水效果达到土体开挖要求；基坑四周设置截水沟及集水坑，防止地表水流入基坑对边坡造成破坏。对深基坑、高边坡设置支护措施：50mm厚C20混凝土护坡内配A4200双向钢筋网片，钢筋网片用C12长400mm，纵横间距为1m插筋固定。On the process, we ensure drainage works fully meet excavation requirements: basins and trench troughs should be set along foundation pits, avoiding rains in destroying sloping. We make supports for deep pits and high sloping: we use 50mm thickness C20 concrete with A4200 two-way fabricated bar (C12, 400mm length) for sloping fixing（spacing 1m with dowel bar).1、 严格按照土方开挖施工方案及相应技术规范要求进行开挖，严禁超挖。1. No over excavations are allowed, all excavation specifications should be in line with required schemes.2、当现场降水等级超过中雨时，根据现场土壤情况，表层土接近或达到饱和，此时严禁进行挖土施工，以免发生机械倾覆等安全事故。2. No accidents allowed. With this in mind, we ensure top soils are dry enough for construction. When heavy rain arrives, we totally stop work for the over- humidity of top soil. 3、现场基槽内如有积水，应立即用水泵抽出，抽放至排水沟。3. We pump out rains which staying in foundation pits. 4、土方开挖时，应安排专人定期观测边坡土体的稳定性，当降水较集中时，应加大观测的次数，发现问题时立即停止开挖及坑底的作业施工。对未来得及做喷射混凝土的边坡，雨前应采用塑料布等覆盖。4. We take a regular look at the stability of sloping. When the heavy rain comes frequently, we should take more looks at sloping stability. In addition, if the sloping is unstable, we should immediately stop the excavation works. For those sloping which are not covered by concrete, we use
