Progressive dynamic compaction construction method and construction equipment thereof
The invention relates to the technical field of construction matching devices, in particular to a progressive dynamic compaction construction method and construction equipment thereof, one-time hammer falling is divided into two or more times of tamping at the same tamping point position, and a certain landing time difference is set between tamping. The landing time difference meets the requirement that the shock waves generated by the previous ramming are applied in a landing mode before the shock waves generated by the previous ramming are not dissipated, so that the shock waves generated by the previous ramming are progressively superposed through the subsequent ramming. The method has the advantages that 1) two or more times of tamping are performed on a single tamping point in one-time drop hammer dynamic tamping, and the construction effect is superposed, so that the total construction time of the tamping point is shortened, and the tamping efficiency is improved; the annular hammer and the solid hammer of the combined hammer set can be connected through a rope and released at the same time, it is guaranteed that the tamping centers are the same, and therefore mutual damage between the rammers is reduced, the annular rammer serves as a main hammer to conduct tamping on the stratum, and the tamping effect on the stratum is more uniform within the effective depth range.
本发明涉及施工配套装置技术领域，尤其是一种递进式强夯施工方法及其施工设备，在同一夯点位置处将一次落锤分为两次或两次以上的夯击，其中夯击之间设置一定的落地时间差，所述落地时间差满足于使后次夯击在前次夯击所产生的冲击波未消散前落地施加，以通过后次夯击对前次夯击所产生的冲击波进行递进式叠加。本发明的优点是：1）在一次落锤强夯中对单夯点进行两次或以上夯击，叠加施工效果，从而减少对夯点的总施工时长，提升夯击效率；2）组合锤组的环形锤与实心锤之间可采用绳索相连，同时释放，确保夯击中心相同，从而减少夯锤与夯锤之间的相互破坏；3）环形夯锤作为主锤对地层进行夯击，在有效深度范围内，对地层夯击效果更为均匀。
