塔靴关系到铁塔的安全稳固。山东枣庄铁塔公司在安全隐患排查中发现,存量铁塔中90%以上的塔靴没有进行包封或者采取空心包法进行包封,塔靴下面的螺丝锈蚀严重,存在严重的安全隐患。为此,枣庄铁塔从3月份开始启动了“固塔行动”,对现网所有地面铁塔的包封进行核查,并针对不同类型隐患进行分类和研究,总结制定了标准工艺流程,遴选优秀的土建队伍,对发现的隐患进行全面整治。
一是全面开展隐患排查,明确整治范围。为保证包封前的铁塔垂直度符合标准,枣庄铁塔从3月份开始,在全市范围内统一组织垂直度测试培训,统一测试标准。各代维单位梳理自己维护区域内所有的地面塔明细,逐个基站进行铁塔垂直度。为了保证工作的成效和检查,各代维单位利用枣庄铁塔APP软件记录并上传现场测试的照片和结果,铁塔公司技术人员从后台提取需要调整垂直度的铁塔明细,安排施工方进行整改。
二是研究分析现网包封隐患。通过排查发现,除了大量没有包封的情况外,已经包封的铁塔塔靴也存在诸多隐患,如包封里面使用泥土,或使用极低标号混凝土材质,或使用用砖做包封材质,还有的塔靴被埋入土中或者被水浸泡,这些情况都会造成塔靴螺栓锈蚀严重。
三是制定标准工艺流程。为规范操作流程,保证施工质量,枣庄铁塔结合前期建设经验,总结编制了《枣庄铁塔塔靴螺栓除锈标准流程》,主要包括:拆除包封、除锈、刷防锈漆3个步骤;总结编制了《枣庄铁塔塔靴包封标准流程》,主要包括:垂直度检查、支模板、调制微膨胀混凝土、震实、完工、质量管控6个步骤。通过标准化的流程规范,可以有效管控施工方的施工操作,做到标准统一、工艺统一、效果统一。
四是遴选优秀土建队伍。枣庄铁塔抽调5名业务骨干人员组成专家组,对目前合作的15家土建施工队伍逐一进行施工质量评分,并按得分高低顺序逐个进行约谈,最终挑选出三家优秀的施工队伍承接塔靴包封工作,从而保证了施工的工艺和质量。
截止目前,枣庄铁塔通过“固塔行动”累计发现各类铁塔塔靴隐患786处(含610处原包封不合格),目前已经完成72座铁塔的塔靴包封整改工作,调整了65座铁塔的垂直度,铁塔的安全性得到了显着的提升,为平稳度过汛期打下了坚实的基础。
The tower boots are related to the safety and stability of the tower. The Shandong Zaozhuang iron tower company found that more than 90% of the tower boots in the storage tower have not been sealed or sealed with hollow bags. The screws underneath the tower boots are corroded seriously, and there are serious safety problems. To this end, the tower of Zaozhuang iron tower started the "action of fixing the tower" from March, inspecting the envelopment of all ground iron towers in the present network, classifying and studying different types of hidden dangers, summarizing and formulating the standard process flow, selecting excellent civil construction teams, and comprehensively regulating the hidden dangers.
First, carry out hidden dangers investigation and clarify the scope of rectification. In order to ensure the verticality of the tower before encapsulation, the tower of Zaozhuang iron tower began in March, unified the verticality test and training in the whole city, and unified the test standard. Each generation unit combs itself to maintain all the ground pagodas in the area, and carries out the vertical alignment of the towers one by one. In order to ensure the effectiveness and inspection of the work, various generation units use the Zaozhuang tower APP software to record and upload the photos and results of the field test. The technical personnel of the tower company extract the detail of the tower from the backstage to adjust the verticality and arrange the construction parties to carry out rectification.
The two is to study and analyze the hidden danger of the present network package. It has been found that, in addition to a large number of non enveloping cases, there are many hidden dangers in the tower boots that have been enclosed, such as the use of clay in the envelops, or the use of extremely low marked concrete, or the use of bricks to cover the material, and the tower boots buried in the soil or soaked by water. The suppository is rusty.
为加快需求交付,及时满足客户网络覆盖要求,淄博分公司多项举措做好需求承接交付工作。
一是未雨绸缪,提前选址。淄博分公司分析以往影响需求交付时间的原因,从16年年底根据客户网络规划进行预选址。在今年移动LTE五期以及移动G网规划中,淄博分公司的预选址比例达63%,极大缩短了需求的交付起租时间,提前满足了客户网络覆盖需求,并增加了自己的营业收入。
二是加强日常对接,增强双方互信。淄博分公司在向客户按时提供服务周报、月报的基础上,还定期组织每周的地市、办事处双方的沟通会,双方在选址以及设计方案上共同协商,更好更快更顺利的满足了客户网络覆盖要求。
三是借力城市规划,引领客户需求。淄博分公司在全力承接客户需求的基础上,根据客户的网络覆盖需要,依托政府融建工作,在各级政府、园林处、规划局等各部门支持下,在公共绿地、景区、以及道路两旁规划了一批站址。目前淄博马踏湖景区规划的4个站点和马南路两侧规划的18个站点均已完工,临淄办事处获批公共绿地零场租的27处站址目前已勘察完毕,准备施工。
四是成立攻坚小组,多元化满足客户需求。淄博分公司为了解决客户多年的硬骨头站址需求,区域双方成立硬骨头站址攻坚小组,双方共同赴现场勘查、讨论,在满足客户覆盖的要求的情况下,采用“一塔变多塔”、室分、微站等多元方式进行覆盖满足。目前针对多年阻工严重的小区,淄博分公司正积极采取路灯杆微站进项覆盖,已有两个实验点已现场勘察待施工进场。
The three is to make standard process flow. In order to standardize the operation process and ensure the construction quality, Zaozhuang iron tower combined with the previous construction experience, summed up the "Zaozhuang iron tower tower shoe bolt rust removing standard process", mainly including:华为ETP4890,ETP4890-A2嵌入式通信电源,ETP4890-A2开关电源,模块电源。 removal of sealing, rust removal, brush antirust paint 3 steps, summary and compilation of "Zaozhuang tower tower shoe sealing standard process", mainly including: verticality 6 steps include checking, formwork, modulating micro expansion concrete, compaction, completion and quality control. Through standardized process specification, the construction operation can be effectively controlled, so as to achieve unified standard, unified process and uniform effect.
Four is the selection of excellent civil construction team. The Zaozhuang iron tower is mad华为ETP4890,ETP4890-A2嵌入式通信电源,ETP4890-A2开关电源,模块电源。e up of 5 professional staff members to make up an expert group. The construction quality score of the 15 civil construction teams is carried out one by one, and according to the order of score and height, three outstanding construction teams are selected to undertake the work of tower boots, thus guaranteeing the construction technology and quality.
Up to now, Zaozhuang tower, through the "action of tower fixing", has found 786 hidden dangers of tower tower boots (including 610 original packages unqualified). At present, the tower boots for 72 towers have been completed, the verticality of 65 tower towers has been adjusted, and the safety of the tower has been greatly improved, which has been laid down in the flood season smoothly. A solid foundation.
