1. Multiple devices (SH) è b è i) Simultaneous operation

这是直接的一个缩短工期的方法，如果是现场允许，并且自己的设备齐全的话可以多台设备同时操作控制，可以有用的缩短时间。强夯置换其特点是：可使用工地常备简单设备；施工工艺、操作简单；适用土质范围广，加固效果显著，可取得较高的承载力，一般地基强度可提高2～5倍；压缩性可降低2～10倍，加固影响深 度可达6～10m；工效高，施工速度快（一般设备每月可加固5000～10000m地基），较换上回填和桩基可缩短工期一半；节省加固原材料；施工费用低，节省投资，比换土回填节省50%费用，与预制桩加固地基相比，可节省投资50%～70%等。

This is a direct way to shorten the construction period. If it is allowed on site, and its own equipment is complete, multiple equipment can be operated and controlled at the same time, which can effectively shorten the time. The features of dynamic compaction replacement are: it can use simple equipment on site; The construction technology and operation are simple; It can be applied to a wide range of soil, and the reinforcement effect is remarkable. It can obtain higher bearing capacity, and the general foundation strength can be increased by 2-5 times; The compressibility can be reduced by 2-10 times, and the reinforcement depth can reach 6-10m; High efficiency and fast construction speed (common equipment can reinforce 5000-10000m foundation per month), which can shorten the construction period by half compared with the replacement of backfill and pile foundation; Save raw materials for reinforcement; The construction cost is low, the investment is saved, the cost is 50% less than that of soil replacement and backfilling, and the investment is 50% ～ 70% less than that of precast pile foundation reinforcement.

强夯机租赁强夯施工结束后应间隔一定时间方能对地基质量进行检验。对于碎石土和砂土地基，其间隔可取1～2周；低饱和度的粉土和黏性土地基可取2～4周。

After the lease of dynamic compaction machine and the completion of dynamic compaction construction, the foundation quality should be inspected at a certain interval. For gravel soil and sand foundation, the interval can be 1-2 weeks; For silty soil and cohesive soil with low saturation, 2-4 weeks can be taken.

2、做好预期

2. Make expectations

每天做一个预期，每周做一个预期。例如今天可以做多少工作，明天可以做多少工作，然后每天每周都把这些工作做完，这样可以增加紧张感。不要小看这一项工作，有的时候做好预期会比不做预期节省(spare)几天的时间。预期其实就是给员工一个目标(cause)，有紧张感。

Make an expectation every day and an expectation every week. For example, how much work you can do today, how much work you can do tomorrow, and then finish it every day and every week, which can increase tension. Don't underestimate this work. Sometimes, it will save a few days to do well than not to do well. Anticipation is actually giving employees a cause and a sense of tension.

3、做好前期交流：这个十分的重要，有的时候交流不到位就会造成后期的停工，或者是返工现象，这样只会增加时间不会缩短时间。交流包含非常多的方面，例如资料的整理，现场的定位，施工技术员的现场测试（TestMeasure)等等，把所有的细节交流到位，并且是记录在案，这样对于后期的施工有很大的便利。

3. Do a good job of early communication: This is very important, sometimes communication is not in place will cause later downtime, or rework phenomenon, this will only increase the time, will not shorten the time. Communication includes many aspects, such as data arrangement, site positioning, construction technician's test measure, etc. all details are communicated in place and recorded, which is very convenient for later construction.

4、做好问题的评估

4. Do a good job in problem assessment

对现场好检验之后，评估一下后期的时候会遇到哪些问题，会需要哪些设备(shèbèi)进行协助。强夯检查强夯施工过程中的各项测试数据和施工记录，不符合设计要求时应补夯和采取其它有用措施。这个时候就需要提前准备(ready)，基本的就是不能耽误设备的运转，不能耽误强夯(hāng)施工，不能出现强夯机械停机等待其他工作。

After on-site inspection, evaluate what problems will be encountered in the later stage and what equipment will be needed (SH) è b è i) Help. Dynamic compaction shall check the test data and construction records in the process of dynamic compaction. If they do not meet the design requirements, supplementary compaction and other useful measures shall be taken. At this time, we need to prepare in advance. The basic thing is not to delay the operation of the equipment and the dynamic compaction (H ā (NG) during the construction, the dynamic compaction machine shall not stop and wait for other work.
