Now many construction teams in the foundation compaction project, generally will adopt the dynamic compaction method to reinforce the foundation, the advantages of dynamic compaction method are very many, the foundation dynamic compaction project for dynamic compaction equipment requirements is also very low, and the construction is convenient, which greatly reduces the construction cost to a certain extent, and its application scope is very wide, in the dynamic compaction construction too The consumption of materials in the project is also very small, and the construction time is short, which can better help the follow-up project to start quickly. So, what control points should we pay attention to when we use dynamic compaction equipment to tamp foundation? Next, we'll learn about the control points of dynamic compaction machine construction!

1.施工前应进行试夯，选定夯锤重量、底面直径和落距，以便确定下沉量及相应的少夯实遍数和总下沉量等施工参数。试夯的密实度和夯实深度必须到达设计要求。

1. Trial compaction shall be carried out before construction, and the weight, bottom diameter and falling distance of rammer shall be selected so as to determine the final settlement, the corresponding minimum tamping times and total settlement and other construction parameters. The compactness and tamping depth of trial compaction must meet the design requirements.

2.基坑的夯实范围应大于基础底面。开挖时，基坑每边比设计宽度加宽不宜小于0.3米，以便于夯实工作的进行，基坑边坡适度放缓。夯实前，基坑底面应高出设计标高，预留土层的厚度可为试夯时的总下沉量加50100毫米。夯实完毕，将基坑表面拍实设计标高。

2. The tamping range of foundation pit should be larger than the bottom of foundation. During excavation, the width of each side of the foundation pit should not be less than 0.3 m than the design width, so as to facilitate the compaction work and slow down the slope of the foundation pit. Before tamping, the bottom of foundation pit shall be higher than the design elevation, and the thickness of reserved soil layer can be the total settlement of trial compaction plus 50-100 mm. After tamping, tamp the surface of foundation pit to the design elevation.

3.做好施工过程中的监测和记录工作，包括检查夯锤重和落距，对夯点放线进行复查，检查夯坑位置，按要求检查每个夯点的夯击次数、每夯的夯沉量等，对各项施工参数、施工过程实施情况做好详细记录，作为质量控制的依据。

3. Do a good job of monitoring and recording in the construction process, including checking the weight and falling distance of the rammer, rechecking the setting out of the tamping point, checking the location of the tamping pit, checking the tamping times of each tamping point and the tamping settlement of each tamping point as required, and making detailed records of the construction parameters and the implementation of the construction process as the basis for quality control.

以上就是关于强夯地基的施工质量要掌握的控制要点，希望能够通过以上的了解能够更好地帮助大家进行强夯工程施工。

The above is about the construction quality of dynamic compaction foundation to grasp the control points, hope to be able to better help you through the above understanding of dynamic compaction engineering construction.
