Description

全预制叠合装配式地下综合管廊及其连接节点 技术领域:
本发明属于市政工程技术领域,具体涉及一种全预制叠合装配式地下综合管廊及其连接节点。
背景技术:
国务院办公厅关于推进城市地下综合管廊建设的指导意见(国办发〔2015〕61号)于2015年8月10日公布。工作目标是到2020年,建成一批具有国际先进水平的地下综合管廊并投入运营,反复开挖地面的“马路拉链”问题明显改善,管线安全水平和防灾抗灾能力明显提升,逐步消除主要街道蜘蛛网式架空线,城市地面景观明显好转。全国各省市的地下综合管廊建设一时之间成为热点。传统的地下管廊建设有两种方式:一、现场现浇,二、工厂预制。
现场现浇地下管廊现场开挖较宽,以保证两侧留有足够的施工操作空间,因此土方开挖量大,回填量也较大;由于所有工作均在现场完成,所以侧墙及顶板均要配置模板,且顶板模板必须要在混凝土完全达到强度后才能拆除,施工周期长,人工需求量大,所有原材料均以散装形式运到现场,污染环境,混凝土现场浇注,人工振捣要求高,如果振捣不实,会留下漏水隐患,而且现场混凝土养护条件差,混凝土出现微裂纹的可能性较大,后期会通过微裂纹渗水。
传统预制管廊由一节一节预制管廊在现场拼接而成,拼接缝较多,拼接缝处的防水要求高,难度大,特别是运输吊装困难,需要大型运输车辆和大型吊装设备,施工成本高;由于一节一节预制管廊是整体工厂预制, 模具复杂,不能流水线生产,制作效率低,而且预制管廊占用空间大,所以单车次运输量小,影响建设速度。
发明内容:
本发明所要解决的技术问题是:解决上述背景技术存在的问题,而提供一种全预制叠合装配式地下综合管廊及其连接节点,通过工厂预制一部分,现场叠合现浇一部分,充分发挥工厂预制质量好、效率高和现场现浇整体性好、结构强度高的优势,克服两者的缺点,改变传统预制管廊生产效率低、运输困难的落后状况,实现现场无模板化施工,环保、节材、优质、高效,并具有优良的防水性能。
本发明采用的技术方案是:一种全预制叠合装配式地下综合管廊,其底板为预制叠合底板,其侧墙或侧墙与中间墙体为预制夹心叠合墙,其顶板为预制叠合顶板,底板、侧墙或侧墙与中间墙体、顶板三者通过现浇连接成整体地下综合管廊。

1)开挖地下管廊;
按略宽于地下管廊宽度开挖地下管廊基坑,并在地下管廊基坑两侧做好护壁;
2)在地下管廊基坑上铺好垫层;
3)用吊车吊起预制叠合底板安装在上述垫层上;
4)预制夹心叠合墙的制备:
a将底层的单层钢筋网片与桁架绑扎,然后单层钢筋网朝下放入模具内定位;
b在模具内浇注混凝土,混凝土应覆盖单层钢筋网片,满足设计的预制夹心叠合墙预制层厚度要求,振捣混凝土;养护;
c养护后,在桁架上面绑扎上层的单层钢筋网片;
d用专用设备吊起上述预制夹心叠合墙的一层预制层及桁架,脱模,并整体翻转;

9)做好防水工程;
10)土方回填。
上述技术方案中,所述的预制夹心叠合墙的现浇层在现场浇注混凝土前为夹心层。
本发明与传统技术相比,具有突出的实质性特点和显著效果:
一、由于传统技术的地下管廊全部现场浇注,因此两侧需要留出足够施工操作空间,基坑开挖较宽,土方开挖量大,回填量也大;而本发明的侧墙和底板、顶板都为工厂预制件,现场装配,基坑开挖不宽,土方量小,回填量小。
二、传统技术的地下管廊全部现场浇注,所有工作量都在现场完成,所以浇注侧墙及底部、顶板均要配置模板,且模板必须要在混凝土完全达到强度后才能拆除,模板量巨大,人工需求量大,施工周期长,而本发明的外墙大部和底板、顶板下部都为工厂预制件,现场装配,无需配置模板,现场工作量少,人工需求量小,施工周期短,建设速度快,效率高。
三、传统技术的地下管廊全部现场浇注,侧墙、底板和顶板均是混凝土现场浇注、人工振捣,质量难以控制,如果振捣不实,就会留下漏水隐患,加上现场混凝土养护条件差,混凝土出现微裂纹的可能性较大,后期通过微裂纹渗水现象严重。而本发明的侧墙和底板、顶板大部都是工厂预制,机器振捣,质量可控,生产效率高,无微裂纹,防水性能好。
四、由于传统技术的工厂预制地下管廊,模具复杂,不能流水线作业,所以生产效率低,而且预制地下管廊体积庞大笨重,运输困难,只能制成很短的一节一节的预制管廊现场拼接,因为预制管廊整体预制,占用空间大,所以单车次的运输小。而这一节一节的预制管廊现场拼接,需配备大型吊装机械作业,一节一节预制管廊拼接缝多,对拼接缝的防水要求高,处理难度大,防水性能差。本发明只在工厂预制夹心叠合墙板和预制叠合板,板与板之间可叠放运输到现场,方便运输,现场组装,部分浇注混凝土,无拼接缝,因而防水性能有保障,而吊装墙板、底板和顶板,无需大型吊装机械作业,节约设备和施工成本。
本发明是一种新型的地下管廊技术体系,通过工厂预制一部分、现场叠合现浇一部分,充分发挥工厂预制和现场浇注两者的优势,克服两者的缺点和不足,特别是既克服了传统预制管廊生产效率低和运输量小的不足,又能让现场无模板化施工,环保节能,效率高,并具有优良的防水性能,为我国建设具有国际先进水平的地下综合管廊并投入运营提供了实施技术。
