Local deep foundation pit supporting construction method under extremely soft soil condition
The invention relates to a local deep foundation pit supporting construction method under the extremely soft soil condition. The method comprises the following steps that firstly, materials are prepared; secondly, a steel plate support caisson is manufactured; thirdly, a steel plate supporting caisson is placed; the method comprises the steps that 1, after a machined caisson is hoisted to the position of an excavated local foundation pit through hoisting machinery such as a tower crane, bottom positioning angle steel is used for positioning, and angle steel and a steel plate on the lower edge of a bottom steel channel frame are pressed into soil through the machinery; 2, the perpendicularity of the caisson is measured, and construction is performed after deviation is adjusted in time, so that the construction quality of the deep foundation pit is ensured; and fourthly, after construction of the local deep foundation pit is completed, the caisson is hoisted out through hoisting equipment and then reused. The support of the local foundation pit under the condition of extremely soft soil texture is newly designed, and the support is simple in manufacturing process, good in safety, capable of saving the construction period, capable of being repeatedly used, economical and practical.
本发明涉及一种极软土质状况下的局部深基坑支护施工方法，包括以下步骤：步骤一：准备材料；步骤二：钢板支护沉箱制作；步骤三：放置钢板支护沉箱；1、利用塔吊等起重机械将加工好的沉箱吊装至开挖完成的局部基坑位置后，利用底部定位角钢定位，用机械将底部槽钢边框下沿的角钢及钢板按入土中；2、测量沉箱的垂直度，有偏差及时调整后再施工，确保深基坑施工质量有保证；步骤四：局部深基坑施工完成后利用起重设备将沉箱吊出后重复利用。本发明对极软土土质状况下局部基坑的支护进行新的设计，做到制作工艺简单、安全性好，节约工期、可重复利用、经济实惠。
