Construction method for improving circular tunnel bottom plate concrete construction quality
The invention discloses a construction method for improving the construction quality of circular tunnel bottom plate concrete, which comprises the following steps of: 1, forming working windows in a bottom template of a lining trolley along the tunnel direction, and forming exhaust holes in the periphery of each working window; secondly, layered warehousing pouring, layered vibrating and exhausting are conducted through a working window; and thirdly, when the distance between the concrete surface and the bottom formwork of the lining trolley is 1-2 cm, the remaining bottom plate concrete is poured through a side window in a side formwork of the lining trolley, and a vibrator is used for vibrating and exhausting. The working window and the exhaust hole are formed in the bottom formwork of the lining trolley, bottom plate concrete pouring is facilitated, vibration observation can also be facilitated, bubbles in the bottom plate concrete are discharged through vibration, gas is smoothly discharged to the outside through the exhaust hole, the appearance quality and the entity quality of circular tunnel lining bottom plate concrete pouring are improved, and the service life of the lining trolley is prolonged. The post-treatment cost and time are reduced, and the construction progress is promoted.
本发明公开了一种提高圆形隧洞底板混凝土施工质量的施工方法，包括：第一步，在衬砌台车的底模板上沿顺隧洞方向开设工作窗口，并在每个工作窗口的四周开设排气孔；第二步，通过工作窗口分层入仓浇筑，分层振捣并排气；第三步，当混凝土面与衬砌台车的底模板之间的距离为1cm～2cm时，通过衬砌台车的侧模板上的侧窗口浇筑剩余的底板混凝土，并利用振动器振捣并排气。本发明在衬砌台车的底模板上设置工作窗口和排气孔，不仅方便浇筑底板混凝土，还能方便振捣观察，以通过振捣将底板混凝土中的气泡排出，排气孔使得气体顺利排出至外界，提高了圆形隧洞衬砌底板混凝土浇筑的外观质量和实体质量，减少了后期处理费用和时间，促进了施工进度。
