高等级公路可液化地基处理方案的确定。

Determination of liquefiable foundation treatment scheme for high-grade highway.

液化地基处理恰当与否，关系到整个工程的质量、投资和进度。因此其重要性已越来越多地被人们所认识工程强夯机租赁。对于高速公路这样大面积处理可液化土而言强夯机租赁，强夯法和干振碎石桩法是的处理手段。

Whether the liquefaction foundation treatment is appropriate or not is related to the quality, investment and progress of the whole project. Therefore, its importance has been more and more recognized by people. For the treatment of liquefiable soil in such a large area as expressway, dynamic compaction method and dry vibration gravel pile method are the most effective treatment methods.

当全液化地基路段较长，需处理面积大，公路沿线外缘较近范围内无村庄，无重要构造物时，强夯法是比较理想的地基处理方法。

When the full liquefied foundation section is long, the treatment area is large, and there are no villages or important structures in the near range of the outer edge of the highway, the dynamic compaction method is an ideal foundation treatment method.

强夯法处理地基是20世纪60年代末Menard技术公司创立的，该方法将80…400kN重锤从落距6—40m处自由落下，给地基以冲击和振动，从而提高地基土的强度并降低其压缩性。强夯法常用来加固碎石、砂土、粘性土、杂填土、湿隐性黄土等各类地基土强夯机租赁。

The dynamic compaction method for foundation treatment was first established by Menard technology company at the end of 1960s The 400kN heavy hammer falls freely from the drop distance of 6-40m to impact and vibrate the foundation, so as to improve the strength of foundation soil and reduce its compressibility. Dynamic compaction method is often used to reinforce gravel, sand, clay, miscellaneous fill, wet hidden loess and other foundation soil.

由于其具有设备简单、施工速度快、适用范围广、节约三材、经济可行、效果显著等优点，经过20多年来的应用与发展，强夯法处理地基受到各国工程界的重视，并得以迅速推广，取得了较大的经济效益和社会效益。

Because of its advantages of simple equipment, fast construction speed, wide application range, saving three materials, economic feasibility and remarkable effect, after more than 20 years of application and development, dynamic compaction method for foundation treatment has been paid attention to by the engineering circles of various countries, and has been rapidly promoted, and has achieved great economic and social benefits.

强夯机租赁注意事项：

Notice for lease of dynamic compaction machine:

1.避震：城市道路强夯需要对周围的建筑物做出分析，如果是江西强夯施工对周围的建筑会造成威胁，就需要提前进行做避震保护。例如深挖避震沟福建强夯机租赁。

1. Shock absorption: the dynamic compaction of urban roads needs to analyze the surrounding buildings. If the dynamic compaction construction in Jiangxi will cause a threat to the surrounding buildings, it needs to be protected in advance. For example, deep excavation of vibration ditch, Fujian dynamic compaction machine rental.

2.注意施工的时间；白天周围的环境比较的嘈杂，强夯施工带来的一些影响其实并不是很大，但是在晚上声音就会传出很远。一般晚八点之后就不要进行施工了，这时间很多的人已经回到家中，如果是声音较大会影响大家休息，对于和谐施工不利。

2. Pay attention to the construction time; the surrounding environment is noisy during the day, and the impact of dynamic compaction construction is not great, but the sound will spread far away at night. Generally, construction should not be carried out after 8 p.m. because many people have already returned home. If the sound is too loud, it will affect everyone's rest, which is not conducive to harmonious construction.

3.周围建设围挡；围挡的目的就是保证施工不被打扰，再者可以有效的防治一些施工的灰尘乱飞。

3. Build enclosure around; the purpose of enclosure is to ensure that the construction will not be disturbed, and it can effectively prevent some construction dust flying around.

4.做好管理工作，城市中道路强夯施工多个工种共同工作，这对于施工有一定的潜在威胁。工作中一定要做好防范。

4. To do a good job in safety management, multiple types of work in urban road dynamic compaction construction work together, which has a certain potential threat to construction safety. We must do a good job of security in our work.
