The common problems such as bridge pier falling and local foundation slope falling after tamping by hydraulic pulley can be solved.

针对常规压实机械折转区、无路地域等现有大型压实或夯实机械不可能接近区域的基础，如桥台背、涵侧、桥墩周边、边坡等液压夯实机均可施工，方便快捷，还有助于截断管涌，特别适应江河堤坝的加固处理及快速抢修。

For the foundation in the turning area of conventional compaction machinery, areas without roads and other areas where the existing large compaction or compaction machinery cannot approach, such as abutment back, culvert side, pier periphery, slope and other hydraulic compactors can be constructed, which is convenient and fast, and also helps to cut off piping, especially suitable for the reinforcement treatment and rapid rush repair of river dikes and dams.

对于初使用者来说，液压夯实机怎样施工、液压夯实机常见的施工方案是什么，尤其需要了解，小编结合多年的生产经验及施工经验，为大家介绍下液压夯实机部分常见的施工方案。

For beginning users, how to construct the hydraulic tamping machine and what are the common construction schemes of the hydraulic tamping machine. In particular, we need to know. Combined with many years of production experience and construction experience, I will introduce some common construction schemes of the hydraulic tamping machine.

首先，试验夯实很重要。由于施工现场地质状况、施工条件，质量要求差异较大，因此，高速液压夯实机的具体施工方法要具体分析对待，不可一概而论。

First, experimental compaction is very important. Due to the great differences in geological conditions, construction conditions and quality requirements at the construction site, the specific construction method of high-speed hydraulic tamping machine should be analyzed and treated in detail, which can not be generalized.

试验夯实通常是在实际施工现场分别做夯点试验，具体为：1档9锤、12锤、15锤布点夯实；2档6锤、9锤、12锤布点夯实；3档6锤、9锤、12锤布点夯实；夯实后测密实度，按可达标档位及对应锤数夯实作业。

The compaction test is usually conducted at the actual construction site, specifically: 1-stage 9-hammer, 12 hammer and 15 hammer point compaction; Point distribution and compaction with 6, 9 and 12 hammers of gear 2; 3 gears, 6 hammers, 9 hammers and 12 hammers for point distribution and compaction; Measure the compactness after tamping, and tamp according to the standard gear and the corresponding number of hammers.

若采用以上试验方法达不到施工要求，可适当增加夯击次数，增加夯击次数仍无法达标的，应考虑更改施工方案。

If the above test methods fail to meet the construction requirements, the number of tamping can be appropriately increased. If the number of tamping still fails to meet the standard, the construction scheme shall be considered to be changed.

冲击夯实试验

施工时，要根据现场情况，如下方有无涵洞、管道，邻近构造物有无冲击力限制等，合理选择施工档位。

During construction, the construction gear shall be reasonably selected according to the site conditions, such as whether there are culverts and pipelines below, whether there are impact force restrictions on adjacent structures, etc.

参照实际实验数据，使用高速液压夯实机对分层碾压达标高速公路路基补强时，用以下施工方案，并应根据实验段数据适当调整。

Referring to the actual experimental data, when using the high-speed hydraulic compactor to reinforce the subgrade of the expressway with layered rolling up to the standard, the following construction scheme shall be used and shall be adjusted appropriately according to the data of the experimental section.
