***大酒店樓房移位工程施工組織設計

一． 工程概況：
***大酒店位于南京市模范馬路南側，是一座接近3星級的酒店，裝修較為豪華，房屋結構為整體六層、局部七層框架，占地面積約700m2，總建筑面積約5400 m2。由于模范馬路拓寬，***大酒店需要拆除。若拆除重建費用較高（含裝潢費用總造價約1860萬），而且工期較長，酒店停業期間會造成較大的間接損失。因此，經市建委和酒店業主公交總公司研究決定采用整體向南平移28米的方案。
新位置處和軌道經過部位的地層和地下水情況見《地質勘察報告》。
二． 平移方案簡介：
平移方案的基本思路是將建筑物和基礎分離，放到移動系統上，移動系統安放到軌梁上，在建筑物一側施加推力或拉力，移動系統和建筑物就會在軌道上移動，到達預定新位置后，將建筑物和新基礎連接。
施工過程如下：
1． 制作下軌道梁并安放滾動裝置。
2． 在滾動裝置上制作上托架。
3． 切斷柱和墻體，使建筑物支撐在移動裝置上。同時切斷水、電管線。
4． 安放反力支座。
5． 施加水平推力，建筑物在軌道上平移。
6． 就位連接。包括其它生活配套設施。
方案的關鍵是托換技術（將建筑物托換到滾動裝置上）、切割技術、同步移動施力系統和就位連接構造。本方案采用安放滾動裝置和同時澆筑上加固梁的托換技術，同先切斷再用千斤頂頂起的托換方法相比，節省頂升千斤頂費用，避免因頂升不同步產生附加應力的危險。同步移動的動力系統采
*** 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
