在煤田地区,特别是在零星开采的小煤窑地区,浅基础井口地基很常见。由于年代已久,一些老井口在地面上很难发现,只有当基槽开挖到一定深度后才能看到,而这时常因已定点的建筑物不能移位而需要对井口进行处理。处理的方法可归纳为以下四点。 In the coalfield area, especially in the small coal mines that are sporadicly mined, shallow foundation wellhead foundations are common. Due to the ages, some old wellheads are difficult to find on the ground. They can only be seen when the foundation trenches are excavated to a certain depth, and the wellhead needs to be dealt with because the fixed-point buildings cannot be displaced. The method of processing can be summarized as the following four points.
