Construction method for supporting and excavating foundation pit of integrated lifting pump station
The invention discloses an integrated lifting pump station foundation pit supporting excavation construction method. The method comprises the following steps that firstly, construction preparation is conducted; secondly, a pipe twisting machine is installed; thirdly, the first section of steel cylinder is hoisted, and the first section of steel cylinder is connected with a driving ring of the pipe rolling machine; fourthly, the first section of steel cylinder is pressed into the soil body while a power system of the pipe rolling machine is used for shaking towards the ground, and when the top face of the first section of steel cylinder sinks to be exposed out of the ground by a certain height, a next section of steel cylinder is welded to the top face, exposed out of the ground, of the first section of steel cylinder; 5, when the power system of the pipe rolling machine cannot press the steel cylinder into the soil, the telescopic arm excavator is adopted to excavate the earthwork in the steel cylinder; sixthly, the fourth step and the fifth step are repeated till the last section of steel cylinder is pressed into the soil body to reach the designed elevation; and seventhly, concrete of the foundation pit bottom plate is poured. According to the construction method, the construction efficiency can be effectively improved, and the construction cost, the safety risk and the environmental protection risk are reduced.
本发明公开了一种一体化提升泵站基坑支护开挖施工方法，包括以下步骤：步骤一，施工准备；步骤二，安装搓管机；步骤三，吊装首节钢制圆筒，并将首节钢制圆筒与搓管机的驱动环连接；步骤四，利用搓管机的动力系统向地面边摇动边将首节钢制圆筒压入土体中，待首节钢制圆筒的顶面下沉至露出地面一定高度时，在露出地面的首节钢制圆筒的顶面上焊接下一节钢制圆筒；步骤五，当搓管机的动力系统无法将钢制圆筒压入土中时，采用伸缩臂挖掘机挖除钢制圆筒中的土方；步骤六，重复步骤四和步骤五，直至将最后一节钢制圆筒压入土体至设计高程；步骤七，浇筑基坑底板的混凝土。本发明的施工方法能有效提高施工效率，降低施工成本、安全风险和环保风险。
