强夯机强夯前应做好夯区地质勘察,对不均匀土层适当增多钻孔和原位测试工作,必要时进行现场试验性强夯,确定强夯施工的各项参数。下面强夯机出租厂家来讲讲强夯机的施工操作工艺注意事项。
Before the dynamic compaction by the dynamic compaction machine, the geological survey of the compaction area shall be done well, and the drilling and in-situ test shall be appropriately increased for the uneven soil layer. If necessary, the field experimental dynamic compaction shall be carried out to determine the parameters of the dynamic compaction construction. Next, the rental manufacturer of the dynamic compaction machine will talk about the construction and operation process precautions of the dynamic compaction machine.
1.强夯施工程序为:
1. Construction procedure of dynamic compaction:
清理、整平场地~标出遍夯点位置、测量场地高程一起重机就位、夯锤对准务点位置一测量夯前锤顶高程一将夯锤吊到预定高度,脱钩自由下落进行奔去,测量锤顶高程~往复奔去,按规定夯击次数及控制标准,完成一个夯点的夯击一重复以上工序,完成遍全部夯点的夯击~用推土机将夯坑填平,测量场地高程一在规定的间隔时间后,按上述程序逐次完成全部夯击遍数~用低能量满夯,将场地表层松土夯实,并测量夯后场地高程。
Clean and level the site - mark the location of each tamping point, measure the elevation of the site, put the heavy machine in place, align the tamping hammer with the service point - measure the elevation of the hammer top before tamping - lift the hammer to the predetermined height, unhook and fall freely to run away, measure the elevation of the hammer top - run back and forth, complete the tamping of one tamping point according to the specified tamping times and control standards - repeat the above procedures, complete the tamping of all tamping points - fill the tamping pit with bulldozer, Survey site elevation I after the specified interval, complete all tamping times one by one according to the above-mentioned procedures to fully tamp with low energy, tamp the loose soil on the surface of the site, and measure the site elevation after tamping.
2.强夯应分段进行,对厂房柱基亦可一排一排夯,起重机直线行驶,从一边向另一边进行,每夯完一遍,用推土机整平场地,放线定位,即可接着进行下一遍夯击。强夯法的加固顺序是:先深后浅,即先加固深层土,再加固中层土,加固表层土。一遍夯完后,再以低能量满夯一遍,有条件的以采用小夯锤夯击为佳。
2. The dynamic compaction shall be carried out in sections. The column foundation of the power house can also be compacted in rows. The crane travels in a straight line from one side to the other. After each compaction, the bulldozer is used to level the site, set out and position, and then the next compaction can be carried out. The reinforcement sequence of the dynamic compaction method is: deep first and then shallow, that is, deep soil is reinforced first, then middle soil is reinforced, and surface soil is reinforced. After the first tamping, the full tamping shall be carried out with low energy. If conditions permit, it is better to use a small rammer for tamping.

3. The column foundation of the plant can also be tamped in rows. The crane runs in a straight line from one side to the other. After each tamping, the bulldozer is used to level the site, set out and position, and then the next tamping can be carried out. The reinforcement sequence of the dynamic compaction method is: deep first and then shallow, that is, deep soil is reinforced first, then middle soil is reinforced, and surface soil is reinforced. After the first tamping, the full tamping shall be carried out with low energy. If conditions permit, it is better to use a small rammer for tamping.
4.夯击时应按试验和设计确定的强夯参数进行,落锤应保持平稳,夯位应准确,夯击坑内积水应及时排除。若错位或坑底倾斜过大,宜用砂上将坑底整平;坑底含水量过大时,可铺砂石后再进行夯击。在每一遍夯击之后,要用新土或周围的土将夯击坑填平,再进行下一遍夯击。强夯后,基坑应及时修整,浇筑混凝土垫层封闭。
4. The tamping shall be carried out according to the dynamic compaction parameters determined by the test and design. The hammer drop shall be stable, the tamping position shall be accurate, and the water in the tamping pit shall be removed in time. In case of dislocation or excessive inclination of pit bottom, the pit bottom should be leveled with sand; When the water content at the bottom of the pit is too large, sand and gravel can be laid before tamping. After each tamping, the tamping pit shall be filled with new soil or surrounding soil before the next tamping. After dynamic compaction, the foundation pit shall be repaired in time, and the concrete cushion shall be poured for sealing.

5.每务击一遍完成后,应测量场地平均下沉量,并做好现场记录。
5. After the completion of each blow, the average settlement of the site shall be measured and the site records shall be made.
6.雨季施工时,夯坑内或夯击过的场地如有积水,应及时排除。夯坑回填土时,宜用推土机稍加压实,并稍高于附近地面,防止坑内填土吸水过多,奔去出现橡皮土现象。
6. During construction in rainy season, if there is water in the tamping pit or tamped site, it shall be removed in time. When tamping the backfill of the pit, the bulldozer should be used to compact it slightly, and it should be slightly higher than the nearby ground, so as to prevent the filling in the pit from absorbing too much water and causing rubber soil.
注意:冬期施工,如地面有积雪,必须。如有冻土层,应先将冻土层击碎,并适当增加夯击数。强夯结束,待孔隙水压力消散后,间隔一定时间后进行检测,检测点数一般不少于3处。关注我们http://www.sddhfjx.cn,了解更多!
Note: during winter construction, if there is snow on the ground, it must be removed. If there is frozen soil layer, the frozen soil layer shall be broken first and the number of tamping shall be appropriately increased. After the completion of dynamic compaction, after the pore water pressure is dissipated, the detection shall be carried out after a certain interval. The number of detection points is generally not less than 3. Follow us http://www.sddhfjx.cn Yes, learn more!
