我公司承建的常德烟厂8层烟叶仓库及6层成品仓库,因楼板每块重量达1.3t,需在原有混凝土马路上安装1台 TQ60/80上回转式塔吊。如采用挖地锚的办法,会破坏原有的混凝土路面;地下水位高,地下1m 处就有水,埋地锚填土要分层夯实,拆除时要挖出地锚,填土分层夯实,还须修补混凝土道路,施工场地狭窄,无处堆放散土。安塔吊工期较长,影响工地正常施工。在这种情况下,我们采取用压重加撑杆的办法代替地锚。把地锚拉力分解成向上的垂直力及对塔吊底座的水平抗滑动
The 8-story tobacco leaf warehouse and the 6-layer finished product warehouse of Changde Cigarette Factory, which was contracted by our company, require a TQ60/80 rotary tower crane to be installed on the original concrete road for a weight of 1.3 tons per floor. If the method of digging the ground anchor is adopted, the original concrete pavement will be damaged; the groundwater level will be high, and there will be water at a place 1m below the ground. The buried anchoring soil must be layered and tamped, and the ground anchors must be excavated during the demolition. It is also necessary to repair the concrete roads. The construction site is narrow and there is no place for dumping. Anta has a long construction period, which affects the normal construction of the site. In this case, we replaced the ground anchors with a weighted strut. Decomposes the ground anchor tension into upward vertical forces and horizontal anti-sliding to the tower base
