处理强夯机施工遇到关键性问题的方法

Methods to deal with key problems encountered in dynamic compaction machine construction

在强夯机施工的过程中，操作人员可能会遇到一些难以处理的问题，而对于这些问题的出现又常常会对于整个施工的质量起着关键的作用，所以说对于这种关键性问题的处理万万不可大意，下边小编就主要对于强夯机施工中遇到的关键问题处理办法进行相应的介绍：

During the construction of dynamic compaction machine, operators may encounter some difficult problems, and the emergence of these problems often plays a key role in the quality of the whole construction. Therefore, the treatment of such key problems must not be careless, The following small series mainly introduces the key problems and treatment methods encountered in the construction of dynamic compactor:

其一、关于局部淤泥包的处理方案。在场地回填过程中，由于填土荷载的作用，淤泥可能会流动，淤泥表面的标高会发生变化，导致场地局部淤积，形成淤泥包。在这种情况下，如果出现在浅层，应该先处理碎石地基，然后进行强夯;如果是在较深的地方，应当提高强夯的能级。

First, the treatment scheme for local sludge bags. In the process of site backfilling, due to the effect of filling load, the sludge may flow, and the elevation of sludge surface will change, resulting in local siltation of the site and the formation of sludge bag. In this case, if it occurs in the shallow layer, the gravel foundation should be treated first, and then dynamic compaction should be carried out; If it is in a deep place, the energy level of dynamic compaction should be improved.

其二、关于夯坑强夯施工的处理方案。强夯时，不得在夯坑底部有水或淤泥的情况下进行施工。如果夯坑内有水或淤泥，应当先降低土壤含水量再进行强夯施工处理。

Second, the treatment scheme of dynamic compaction construction of tamping pit. During dynamic compaction, construction shall not be carried out when there is water or sludge at the bottom of the tamping pit. If there is water or sludge in the tamping pit, the soil water content shall be reduced first, and then the dynamic compaction construction treatment shall be carried out.

其三、关于地面隆起的处理方案。强夯过程中，如果地面隆起影响施工，应该及时开挖隆起。如果隆起土方为淤泥，应适当开挖到一定深，然后用碎石土回填夯面标高，并继续进行强夯施工，以保证强夯施工设备的正常运行。

Third, the treatment scheme of ground uplift. During dynamic compaction, if the ground heave affects the construction, the heave shall be excavated in time. If the uplifted earth is silt, it shall be properly excavated to a certain depth, then backfilled with gravelly soil to the tamping surface elevation, and the dynamic compaction construction shall be continued to ensure the normal operation of the dynamic compaction construction equipment.
