立交桥泵站深基坑施工应急预案

一、应急预案的方针与原则
坚持“安全第一，预防为主”、“保护人员安全优先，保护环境优先”的方针，贯彻“常备不懈、统一指挥、高效协调、持续改进”的原则。更好地适应法律和经济活动的要求；给企业员工的工作和施工场区周围居民提供更好更安全的环境；保证各种应急资源处于良好的备战状态；指导应急行动按计划有序地进行；防止因应急行动组织不力或现场救援工作的无序和混乱而延误事故的应急救援；有效地避免或降低人员伤亡和财产损失；帮助实现应急行动的快速、有序、高效；充分体现应急救援的“应急精神”。
二、应急策划
(一)工程概况及地质条件
(1)工程概况
济南市城区工程建设指挥部拟在经十路南侧、铁西路东侧修建一座泵房站，建筑物长22.00米，宽度2.8－11.5米，基坑开挖深度12.00米，根据场地工程地质及水文地质条件，在基坑开挖和使用过程中需要进行临时性基坑支护。
 (2)工程地质
1、岩土工程条件
拟建场地地形平坦，地貌单元为山前冲洪积平原下部，场区内与基坑支护工程有关的底层主要为上部的填土及下部的冲洪积粉土和粘性土。
Overpass contingency plans for deep excavation pump

First, the policy and principles of the emergency plan
Adhere to the "safety first, prevention first" and "protecting the safety of priority, to protect the environment first" approach, implementation of the "safety, unity of command, and efficient coordination and continuous improvement" principle. Better adapt to the requirements of law and economic activities; to the work of employees and residents around the construction site area better and more secure environment; to ensure all emergency resources in a good state of readiness; guide emergency operations planned and orderly ; prevent inadequate emergency response organizations or on-site rescue the disorder and confusion and delay emergency plan; effectively avoid or reduce casualties and property losses; help achieve rapid response, orderly, and efficient; fully reflect the emergency rescue "contingency spirit."
Second, contingency planning
(A) Survey and Geological Engineering
(1) Project Overview
Construction headquarters in Jinan City to be in the south by the 10 Road, Rail Road east to build a pump station, building long 22.00 meters, width 2.8-11.5 m, excavation depth 12.00 m, according to geological sites and hydrological and geological conditions, in the excavation and the need for temporary use during excavation.
 (2) Engineering Geology
1, geotechnical engineering conditions
The proposed flat site topography, geomorphology units for the piedmont alluvial plain of the lower part of field excavation projects in the region and the bottom of the main filling the top and bottom of the alluvial silt and clay.
