***大酒店楼房移位工程施工组织设计

一． 工程概况：
***大酒店位于南京市模范马路南侧，是一座接近3星级的酒店，装修较为豪华，房屋结构为整体六层、局部七层框架，占地面积约700m2，总建筑面积约5400 m2。由于模范马路拓宽，***大酒店需要拆除。若拆除重建费用较高（含装潢费用总造价约1860万），而且工期较长，酒店停业期间会造成较大的间接损失。因此，经市建委和酒店业主公交总公司研究决定采用整体向南平移28米的方案。
新位置处和轨道经过部位的地层和地下水情况见《地质勘察报告》。
二． 平移方案简介：
平移方案的基本思路是将建筑物和基础分离，放到移动系统上，移动系统安放到轨梁上，在建筑物一侧施加推力或拉力，移动系统和建筑物就会在轨道上移动，到达预定新位置后，将建筑物和新基础连接。
施工过程如下：
1． 制作下轨道梁并安放滚动装置。
2． 在滚动装置上制作上托架。
3． 切断柱和墙体，使建筑物支撑在移动装置上。同时切断水、电管线。
4． 安放反力支座。
5． 施加水平推力，建筑物在轨道上平移。
6． 就位连接。包括其它生活配套设施。
方案的关键是托换技术（将建筑物托换到滚动装置上）、切割技术、同步移动施力系统和就位连接构造。本方案采用安放滚动装置和同时浇筑上加固梁的托换技术，同先切断再用千斤顶顶起的托换方法相比，节省顶升千斤顶费用，避免因顶升不同步产生附加应力的危险。同步移动的动力系统采
*** Hotel building construction organization design displacement

1. Project Overview:
*** Hotel is located in Nanjing, the south side of the road model, is a nearly 3-star hotel, the decoration is more luxurious, the overall structure of six houses, seven local framework, covers an area of about 700m2, total construction area of about 5400 m2 . As a model road widening, *** Hotel need to be removed. If the higher cost of demolition and reconstruction (including the decoration costs of about 18.6 million total cost), and a longer duration, the hotel will result in the closure period greater indirect losses. Therefore, the Municipal Construction Commission and the hotel owners decided to use Public Transport Company of overall southward shift of 28 meters of the program.
Department through the new location and orbital parts of strata and groundwater conditions, see "geological survey report."
2. Translation program profiles:
The basic idea is to shift the program will be the basis of the building and separated into mobile systems, mobile systems to track the beam placed in the buildings impose thrust or pull side, mobile systems and buildings will be moving in orbit, to reach Book a new location, will be the basis of the building and the new connection.
Construction process is as follows:
1. Produced and placed under the rail beam rolling device.
2. Produced on a rolling device bracket.
3. Cut off the columns and walls, to building support for mobile devices. At the same time cutting off water and electricity lines.
4. Placement reaction bearing.
Five. Applied horizontal force, building on the shift in orbit.
6. Place to connect. Including other living facilities.
Program is the key underpinning technologies (underpinning the building to the rolling device), cutting technology, synchronous mobile force on the system and place the bolts. The program uses the same time pouring device and placed on a rolling reinforcement beam underpinning, with the first cut since then jack Underpinning methods, lifting jack to save costs, avoid lifting of sync the risk of additional stress. Adoption of mobile power system synchronization
