求翻译：成孔顺序：挖掘程序将以土层性质确定，土层紧密、地下水位不大者，集中一角抽水，以降低其水位。土层松软、地下水位较高者，采用对角开挖，避免孔间间隔层太薄造成坍塌。是什么意思？

Hole sequence: excavation process will determine the nature of soil, soil close, the water table is not who focus on the corner of pumping to reduce its water level. Soft soil, the higher water table, using the diagonal excavation, the interval between the layer is too thin to avoid the hole caused

cheng gong sequence: exhumation procedures will be determined by nature and the soil layer, and the soil layer is not close, groundwater pumping, focus on one point, in order to reduce its water level. Layer loose, groundwater levels, higher-point digging holes, so as to avoid causing collapse too t

Becomes the hole order: The excavation procedure determined by the soil layer nature that, soil layer close, subsoil water level not big, concentrates a jiao pump, reduces its water level.Soil layer soft, subsoil water level high, uses the opposite angle to excavate, avoids the panel gap level too b

Poreforming order: mining procedures to soil properties determine, soil, groundwater is not closely, a corner of Central pump, to lower the water level. Soil is soft, high groundwater level, using diagonal excavation, avoid collapse holes between every layer is too thin.

Hole sequence: excavation process will determine the nature of soil, soil close, the water table is not who focus on the corner of pumping to reduce its water level. Soft soil, the higher water table, using the diagonal excavation, the interval between the layer is too thin to avoid the hole caused
