1、强夯施工宜在干旱季节进行,在雨季施工时应采取措施防止场地积水,导致土质变软,出现挤出现象,降低强夯效果。
1. Dynamic compaction construction should be carried out in dry season, and measures should be taken to prevent site water accumulation during rainy season, resulting in soil softening, crowding phenomenon and reducing dynamic compaction effect.
2、根据强夯施工图利用自然地形确定明沟排水方向,按规定坡度开挖明沟,以确保强夯施工质量。
2. According to the dynamic consolidation construction drawing, the drainage direction of the open ditch is determined by using natural terrain, and the open ditch is excavated according to the specified gradient to ensure the quality of the dynamic consolidation construction.
3、对强夯区域及时进行表面碾压。
3. Surface rolling of dynamic compaction area in time.
4、掌握天气变化情况,做到事先预防。
4. Grasp the weather change and prevent it beforehand.
5、履带式强夯机在雨期强夯时,严禁在未经夯实的虚土上或低洼处作业,同时进行预夯试吊,反复将夯锤吊离地面1m以上起落数次,确定稳定后方可进行强夯。
5. When the crawler dynamic compactor is in the rainy season, it is strictly forbidden to work on the unreinforced virtual soil or low-lying areas. At the same time, the pre-compaction test crane is carried out, and the tamping hammer is repeatedly hoisted from the ground for more than 1 m to take off and fall several times. It is determined that the dynamic compaction can be carried out only after stabilization.
6、使用轮胎式超重机时,在强夯和移机过程中均应铺设垫板
6. When using tyre type overweight machine, cushion plate should be laid during dynamic compaction and moving process.
