安装单位应组织安装技术人员进行现场勘察

安装单位应组织安装技术人员进行现场勘察 安装单位应组织安装技术人员进行现场勘察 近些年来，随着我国经济的持续稳定发展，工程建设的规模也越来越大，高层建筑大量涌现，建筑施工中投入的建筑起重设备日趋增多，尤其是塔式起重机和施工升降机使用较多，机电方面安全管理的工作量及难度也随之增加。但由于当前建筑市场还不够完全规范，部分施工单位对安全管理的形势和风险认识不足，在资金和人员投入上明显不足，故监理单位对起重机械安全使用方面的安全监理工作要更加积极主动。下面以本人监理的一个项目为例，和大家一起探讨如何做好建筑机电设备安全监理工作。In recent years, along with our country economy sustained and stable development, the scale of the project construction is becoming more and more big, high-rise buildings springing up, the investment in the construction of construction lifting equipment increasing, especially the tower crane and construction hoist use is more, mechanical and electrical aspects of safety management of the workload and difficulty also will increase. But due to the current construction market is not enough completely specification, part construction units insufficient understanding of the situation of safety management and risk, in money and personnel, so the supervision company for safe use of lifting machinery safety supervision work to be more proactive. Here in my supervision of a project, for example, to discuss with you how to do a good job of building mechanical and electrical equipment safety supervision. 一、工程安全评估及目标A, engineering safety assessment and goal 本项目由中建系统某下属公司总承包，虽然总承包单位的资质等级为特级，但报建的项目经理不到位，现场技术及管理人员较少，安全管理人员仅3名，且无专业机电方面人员，施工方的机电管理力量明显薄弱。本项目总工期较短，投入使用的建筑起重设备多，存在的交叉作业也较多，时有加班抢工现象，很容易出现安全监管漏洞。而建筑起重设备的使用事关公众安全，近几年来高层建筑由塔吊、施工升降机不当使用及违规安装、拆除引发的安全事故不在少数，所以塔吊、人货电梯的安全监管工作必须扎实、严密，来不得半点疏忽。本项目的安全管理目标是自始至终不发生重大安全事故和人身伤亡事故，塔吊、施工升降机的安全监管是不可忽视的一个重要环节。监理机构应充分认识到本项目起重设备安全监管任务的复杂性，对塔吊及升降机等起重设备在安装、拆除、使用、维护等关健环节要采取积极主动的安全监理，确保本项目所用的塔吊（升降机）等安装、拆除及使用过程自始至终不出现安全事故及未遂安全事故。Some subordinate company general contracting this project by the build system, while the overall contractor qualification level as special, but to establish the project manager does not reach the designated position, on-site technical and management personnel is less, only 3 safety management personnel, and no professional mechanical and electrical aspects, construction of mechanical and electrical power management is obvious weak. This total project duration is shorter, put into use of construction lifting equipment, existing cross homework more, also often work overtime to rob workers phenomenon, it is easy to appear safety regulatory loopholes. And the use of construction lifting equipment is a matter of public safety, high-rise buildings in recent years by the tower crane, construction elevator misuse and illegal installation, dismantle safety accident caused by not a few, therefore, tower crane, one cargo lift safety supervision must be solid, closely, which permits no neglect. The safety management objectives of this project is not a major safety accident and casualty accidents, tower crane, construction elevator safety regulation is an important link of cannot be ignored. Supervision agency should fully realize the project hoisting equipment safety supervision of the complexity of the task, for tower crane and hoist and other lifting equipment during the installation, dismantling, operation and maintenance and so on key link to take active safety supervision, to ensure that the tower crane used in this project (elevator) and other installation, removal and use process from beginning to end not attempted safety accident and safety accidents. 二、安全监理工作措施几点概述Second, some overview of work safety supervision and management measures 1.总监理工程师亲自布置与检查安全方面的有关工作1. The general supervision engineer personally arrangement related to check the safety work 通过安全方面的评估，本项目的安全生产形势不容乐观，稍有懈怠，可能会发生安全事故，尤其是起重机械使用方面。总监本人对本项目施工始终紧绷着一根时刻要安全的弦，时刻保持与业主、总包单位的沟通交流，提倡三方每周对施工现场进行一次安全专项检查。每次周检查监理人员都积极参加，尤其重视对塔吊、施工升降机的检查，监理组安排机电专业监理工程师负责塔吊、施工升降机及临时用电方面的安全监理工作，总监经常对监理组的安全监管工作进行检查。Through safety evaluation, the objective of the production safety situation is not optimistic, fact, safety accident may occur, especially the use of hoisting machinery. Director himself to this project construction always tight string with a moment to safety, keep communication with owner, the contractor unit, advocates the three parties to the construction site safety special inspection once a week. Took an active part in each week inspection supervision personnel, especially the value of tower crane, construction elevator inspection and supervision group of mechanical and electrical professional supervision engineer is responsible for the tower crane, construction elevator and temporary electricity utilization in terms of work safety supervision, director of group supervision often inspect safety supervision work. 2.定期组织学习，提高监理人员安全监管水平2. Organize regular learning, improve the level of supervision personnel safety regulation 监理组通常每半月进行一次安全学习，通过学习，监理人员熟悉了塔吊、施工升降机等的建筑机械的工作原理，另一方面也提高了安全风险意识和法律责任意识，从而提高了对建筑机械设备安全监理的能力和力度。就以通联QTZ63B塔吊为例， 该塔吊额定起重力矩72t.m，最大工作幅度55m，最大起重量为6t，最大起重力矩为84tm，最大附着起升高度为140m。为了保证塔机工作的稳定性和整机刚性，减少上部塔身的自由长度，在塔身全高设置四套附着架，四套附着相对位置h1=31.5m，h2=27.5m，h3=25m，h4=25m。每节标准节长度为2.5m。监理学习后就很清楚地知道塔吊安装附着的具体要求，也就是不超过12个标准节必须安装首道附着，其后是不得超过11、10、10个标准节应安装第二、三、四道附着。Supervision group usually once every half month to safety study, through the study, supervision personnel familiar with the tower crane, construction elevator construction machinery works, on the other hand also improves the security risk consciousness and legal responsibility consciousness, to improve the ability of safety supervision of construction machinery equipment and strength. As tonly QTZ63B tower crane as an example, the crane rated lifting moment 72 t. m, the maximum working range 55 m, maximum weight of 6 t, the largest lifting torque of 84 tm, biggest adherent lifting height is 140 m. In order to ensure the stability of tower crane and the rigidity, reduce the free length of the upper tower, four sets of attachment is set in the towers are all high, four sets of attached relative position h1 = 31.5 m, h2 = 27.5 m, h3 = 25 m, h4 = 25 m. Each section length is 2.5 m. Supervising learning know very well that after the tower crane installation to the specific requirements of the attachment, which is not more than 12 standard attached section must be installed first, followed by shall not exceed 11, 10, 10 standard section should be installed the second, three, four attachment. 3.定期检查安全漏洞，分析安全形势，制定安全监理措施。3. Regularly check the security vulnerabilities, analyze the security situation, make the safety supervision measures. 项目监理组通常每月召开一次安全形势的评估分析会议，重点进行安全形势分析。对塔吊、人货电梯的初安装、加节、附着安装、拆除施工等关键环节可能出现的问题或隐患进行分析，制定安全监理措施。监理人员定期对现场使用的塔吊、人货电梯的操作使用、运行、维护、保养、人员上岗等情况进行监督检查，查找施工方在安全监管上漏洞，督促施工完善监管措施，及时消除安全隐患。Project supervision group are usually held once a month security assessment of the situation analysis meeting, focus on analysis the security situation. For tower crane, cargo elevator installation, add section, at the beginning of such key links as attached installation, demolition of construction possible problems or hidden dangers were analyzed, and the safety supervision measures. Supervisory staff on a regular basis for field use of tower crane and one cargo lift operation, operation, maintenance, maintenance, staff, and so on and so forth, conducting supervision and inspection to find loopholes in safety supervision, quality supervise construction perfect regulatory measures, timely eliminate safe hidden trouble. 4.重点审查塔吊、施工升降机、物料提升机的安装（拆卸）专项施工方案，在巡视中检查方案落实情况4. Focus on review the installation of the tower crane, construction elevator, material hoist (remove) special construction plan, during a tour of inspection scheme to carry out the situation 项目监理机构从安全角度应重点审查以下几方面内容：1）选用的设备是否满足项目施工需要2）设备基础方案、平台方案是否满足安装需要，主要查看计算书；3）安装（拆卸）单位资质、人员是否符合要求；4）安装（拆卸）作业对周边环境设施是否有影响，实施前是否履行告知义务；5）设备安全管理协议、安全交底、应急救援预案等是否齐全，这些方案审查通过后，组织监理人员进行学习、交底，使监理人员掌握设备的关键技术指标及有关参数，以便监理人员在巡视时能够检查发现问题。Project supervision mechanism from a security perspective review should focus on the following aspects: 1) selection of equipment whether meet the needs of the project construction scheme, 2) equipment foundation platform solutions whether meet the requirements of installation, mainly to check the calculations; 3) install (remove) unit qualification, personnel is in line with the requirements; 4) installation (remove) homework, does this have any impact on surrounding environment facilities, whether before the implementation performance of the inform obligation; 5) equipment safety management, safety disclosure agreement, such as contingency plan is complete, these solutions, after the assessment, disclosure supervision personnel for organizational learning, the key technical indicators of supervisory staff to grasp equipment and related parameters, so that when a supervisory staff on patrol inspection found the problem. 5.在巡视检查中注重检查是否存在安全隐患5. Pay attention to check whether there is potential safety hazard in the patrol inspection 项目监理机构的每一个成员在巡视检查时均要关注机电设备的安全情况，在监理工作初期未进行专门的安全隐患巡视记录，后来总监认为不进行专项的安全记录（平行检查），监理人员在巡视中容易忽视安全情况，尤其是机电方面的安全。因此在后期实行了专门的安全巡视记录，专门记录安全隐患的发现及处理情况，并将有关情况告知业主和施工单位。Project supervision institutions of every member in the patrol inspection when all attention to the security situation, the mechanical and electrical equipment at the beginning of the supervision work without special security patrol record, then director think without special safety record (parallel) examination, supervision of staff in the tour is easy to ignore the security situation, especially mechanical and electrical safety. So in the later has a dedicated security patrol record, record the safety problems found and processing conditions, and shall inform owner and the construction of the relevant units. 三、起重机械设备安全监理监控要点Three, lifting machinery safety supervision control points 1. 监理要点：1.
