Overview
Service overview
This service is designed for building rectification, foundation reinforcement, bridge jacking, bridge slope adjustment, structural strengthening and complex urban renewal projects. It provides design consulting, technical scheme development, structural analysis, construction-method recommendations and construction-stage technical support. It is applicable to engineering issues such as uneven settlement, structural inclination, foundation defects, wall cracking, road or bridge elevation adjustment and functional upgrading of existing structures.
Based on the structural conditions, construction constraints, safety control requirements and future use objectives of a project, the company can propose coordinated solutions for jacking, reinforcement, underpinning, rectification and monitoring. This type of service emphasizes the integration of design schemes with construction feasibility, focusing on both structural safety and risk and deformation control during construction.
该服务面向建筑纠偏、基础加固、桥梁顶升、桥梁调坡、结构加固和城市更新复杂工程，提供设计咨询、技术方案编制、结构分析、施工工艺建议和施工阶段技术配合等服务。服务适用于不均匀沉降、结构倾斜、基础缺陷、墙体开裂、道路或桥梁标高调整、既有结构功能提升等工程问题。
公司可根据项目结构条件、施工约束、安全控制要求和后续使用目标，提出顶升、加固、托换、纠偏和监测协同方案。该类服务强调设计方案与施工可实施性的结合，既关注结构安全，也关注施工阶段的风险控制和变形控制。

Technical Details & Applications
Representative Project References
Company project: Daishan Petrochemical Circular Economy Industrial Park Workshop No. 6 jacking and rectification design project. The project is located in Zhoushan. Due to pile foundation quality issues, the building experienced significant uneven settlement and tilted eastward as a whole, with a maximum settlement exceeding 50 cm. The design adopted foundation supplemental piling reinforcement and an active lifting rectification scheme for repair and reinforcement.
Company project: Foundation reinforcement and jacking rectification design project for the building at No. 108 Hangwan Road, Nanhui New Town, Pudong New Area. The project is located in Shanghai. It involved a five-storey brick-concrete structure with a raft foundation and a building area of approximately 1,000 m². Drainage improvement works nearby caused wall cracking. The design used 57 square piles of 250 mm for foundation reinforcement and 33 jacks of 200 tonnes, with a PLC hydraulic synchronous control system, to carry out column-cutting jacking and rectification.
Company project: Nanning Lingli Bridge jacking modification project. Due to navigation-channel upgrading, the north and south approach bridges were jacked and modified. The maximum jacking height was 2.3 m and the total jacking area was 30,000 m². A slope-adjustment jacking scheme was adopted in the design.
Company project: Luoyang Peony Pavilion viewing platform jacking, rectification and reinforcement project. The project has a building area of 1,557.83 m². Foundation sliding caused structural columns to tilt and led to uneven settlement of the upper platform. Local foundation reinforcement, local column reinforcement and local jacking were adopted to restore the structure to its original state.
技术说明与应用案例
代表项目参考
公司案例：岱山石化循环经济产业园6#车间顶升纠偏设计项目 项目位于舟山市，因桩基质量影响，建筑出现较大不均匀沉降并整体向东倾斜，最大沉降量超过50cm。设计采用基础补桩加固、主动提升纠偏方案进行维修加固。
公司案例：浦东新区南汇新城镇杭湾路108号房屋基础加固及顶升纠偏设计工程 项目位于上海市，为五层砖混结构、筏板基础，建筑面积约1000㎡。周边排水改造工程导致墙体开裂，设计采用57根250mm方桩进行基础加固，并使用33台200t千斤顶，由PLC液压同步控制系统进行断柱顶升纠偏。
公司案例：南宁市伶俐大桥顶升改造工程 项目因航道升级对南北引桥进行顶升改造，最大顶升高度2.3m，总顶升面积30000㎡，设计采用调坡顶升方案。
公司案例：洛阳牡丹阁观景平台顶升纠偏加固项目 项目建筑总面积1557.83㎡，因基础滑移造成结构柱倾斜，并导致上部平台不均匀沉降。项目采用局部基础加固、局部柱加固和局部顶升方式，使结构恢复至原始状态。
