Weekly Report: Base Installation for Wayfinding Signage

Weekly Report: Base Installation for Wayfinding Signage

This week, the primary focus is mapping out locations and utility lines for the park's signage system. We are now entering the foundational phase, starting with location verification. Compare drawing coordinates against on-site features to confirm the alignment and burial depth of underground water supply, drainage, power, and communication lines. For sections involving municipal roads, coordinate with relevant authorities for validation. Inaccurate location data will compromise all subsequent work.

本周主线先把点位与管线摸清

园区导视牌本周进入基础阶段,我们先做点位复核。图纸坐标与现场地物比对,确认地下给排水、电力与通信管线的走向与埋深,涉及市政路段的还需与相关管理单位核对。点位定不准,后面所有工序都在返工。

基槽开挖与垫层

按设计尺寸放线开挖,槽底整平夯实后铺垫层。雨季施工要留排水坡度,槽内积水必须清干净再进下一道工序,否则混凝土与基底粘结受影响,后期沉降直接反映在牌体垂直度上。

预埋件定位是核心环节

地脚螺栓组与钢筋骨架绑扎后入模,用型钢架固定螺栓上口,防止浇筑时位移。螺栓间距、外露长度、对角线偏差逐项复测并记录,与导视牌底座孔位对得上才算合格。螺纹部分缠胶带保护,避免浆液污染。

钢筋骨架协同

钢筋网按图绑扎,保护层垫块布点均匀,地脚螺栓组与钢筋骨架冲突时先调钢筋、后动螺栓孔位,孔位以底座样板复核。我们习惯在合模前做一次联合校验:结构、水电、标识三方图纸叠图,把碰撞点消灭在浇筑前。

浇筑与养护按记录走

混凝土按设计标号浇筑,振捣密实不留蜂窝,顶面收光找平。终凝后覆盖洒水养护,达到强度前不安排吊装。同期留置试块,作为验收与追溯依据,浇筑日期与方量写入施工记录。

不同点位的固定选择

户外立柱与精神堡垒走预埋加二次灌浆;立柱类导视牌多用抱箍与背栓固定,不破坏柱体结构。配图为该类作业的现场记录:牌体分片包覆于雨棚立柱钢结构,作业人员登高对位,地面构件按编号待装。两类方式的验收重点不同:预埋看垂直度与螺栓偏差,抱箍看紧固点间距与柱面保护。

隐蔽记录与照片留档

基槽尺寸、钢筋规格与螺栓组定位在覆盖前拍照,并填写隐蔽验收记录,标注日期与点位编号。回填分层夯实,每层厚度写入记录,防止一次填满留下后期沉降。

常见偏差与纠正方式

螺栓组位移多因架固刚度不足,浇筑前需二次复测;基础水平度超差用垫片与二次灌浆调整,不靠牌体自身校正;养护期不足即吊装会造成倾斜,判定以试块与强度记录为准。

下周衔接

基础复测完成后进入构件吊装准备,同步确认运输路线与吊装设备站位,避开园区高峰时段,减少现场等待。周记随进度滚动更新,下周主线转入牌体拼装与垂直度初校。
