强夯机使用的强夯法优点见效好可推荐

现在的建筑工程的地基都需要对松土进行压实处理,也就都离不开打夯,小的建筑工程夯实地基用小的电动打夯机就能完成,较大的建筑工程通常对地基都有着硬性的指标,需要夯实到某种程度才算合格,这样就对打夯机有了某些指标上的要求,因此就需要用到强夯机。
At present, the foundation of construction projects requires compaction of loose soil, which is inseparable from tamping. Tamping the foundation of small construction projects can be completed with a small electric tamping machine. Larger construction projects usually have hard indicators for the foundation, and they need to be tamped to a certain extent before they are qualified. In this way, there are certain indicators for the tamping machine, so the dynamic tamping machine is required.
强夯法即强力夯实法,又称动力固结法。是利用大型履带式强夯机将8-30吨的重锤从6-30米高度自由落下,对土进行强力夯实,迅速提高地基的承载力及压缩模量,形成比较均匀的、密实的地基,在地基一定深度内改变了地基土的孔隙分布。强夯法施工已广泛运用到高速公路铁路,机场、核电站、大工业区、港口填海等基础加固工程。优点工期短、效果好、造价低。
Dynamic compaction method is also called dynamic consolidation method. A large crawler type dynamic compactor is used to free fall 8-30 tons of heavy hammer from a height of 6-30 meters to strongly compact the soil, rapidly improve the bearing capacity and compression modulus of the foundation, form a relatively uniform and dense foundation, and change the pore distribution of the foundation soil within a certain depth of the foundation. The dynamic compaction method has been widely used in the foundation reinforcement projects of expressways, railways, airports, nuclear power plants, large industrial areas, port reclamation and so on. The utility model has the advantages of short construction period, good effect and low cost.
强夯机租赁厂家认为强夯法适用于处理碎石土、砂土、低饱和度的粉土与粘性土、湿陷性黄土、素填土和杂填土等地基。强夯施工前,应在施工现场有代表性的场地上选取一个或几个试验区,进行试夯或试验性施工。试验区数量应根据建筑场地复杂程度、建设规模及建筑类型确定。
The dynamic compaction machine rental manufacturer believes that the dynamic compaction method is applicable to the treatment of gravel soil, sandy soil, silt and clay with low saturation, collapsible loess, plain fill and miscellaneous fill and other foundations. Before dynamic compaction construction, one or several test areas shall be selected on the representative site of the construction site for trial compaction or experimental construction. The number of test areas shall be determined according to the complexity of the construction site, construction scale and building type.

强夯机设备施工的优点有哪些?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。
What are the advantages of dynamic compaction machine construction? Simple construction process and operation; It is applicable to a wide range of soil, with remarkable reinforcement effect. It can obtain high 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 influence depth of reinforcement can reach 6 ~ 10m; High work efficiency and fast construction speed (general equipment can reinforce 5000 ~ 10000m foundation per month), which can shorten the construction period by half compared with backfilling and pile foundation; Save reinforcement raw materials; The construction cost is low and the investment is saved, which is 50% less than that of soil replacement and backfilling, and 50% ~ 70% less than that of precast pile foundation reinforcement.
此外正确的施工事项要了解到,比如认真调查,确保强夯场地范围内的地下无构筑物。清除地表土,清除范围为路基坡脚外2~3m。整平后在场地上标出一遍夯点的位置,点位偏差控制在±20cm范围内,并测量场地高程。起重机就位,使夯锤对准夯点位置,测量夯前锤顶高程。
In addition, correct construction matters should be understood, such as careful investigation to ensure that there are no underground structures within the dynamic compaction site. The surface soil shall be removed within 2 ~ 3M outside the subgrade slope toe. After leveling, mark the position of one tamping point on the site, control the point position deviation within ± 20cm, and measure the site elevation. The crane shall be in place to align the rammer with the tamping point and measure the hammer top elevation before tamping.
