Dynamic compaction construction method for high-filled roadbed
The invention discloses a dynamic compaction construction method for a high-filled roadbed. The dynamic compaction construction method comprises the following steps of (S1) flattening a field; (S2) drawing arrangement diagrams of first-time tamping points and second-time tamping points by applying CAD, and extracting coordinates of all the tamping points; (S3) marking the positions of the first-time tamping points on the construction site by using marking lines according to the coordinates of the tamping points, and measuring the elevation of the tamping points; (S4) putting a tamping machine in place, and performing dynamic compaction operation on the tamping point positions according to the principle of interlaced jumping from inside to outside; (S5) bulldozing a tamping pit formed during first-time tamping by using a bulldozer, and setting out the positions of the second-time tamping points by using marking lines; and then tamping all the second-time tamping points according to the tamping method and sequence of the tamping operation in the step (S4), and interrupting the dynamic compaction once after a certain period of time; (S6) performing full tamping construction, wherein during tamping, a tamping mark between two tamping points is in lap joint with 1/4 hammer diameter for tamping; (S7) tamping the first-time tamping points and the second-time tamping points again according to the construction methods from (S3) to (S6); and (S8) rolling the rammed roadbed by using a road roller.
本发明公开了一种高填方路基强夯施工方法，包括如下步骤：S1，平场；S2，应用CAD绘制出第一遍夯点和第二遍夯点的布置图并提取各个夯点坐标；S3，根据夯点坐标，在施工场地上用标线标示出第一遍夯点的位置，测量夯点高程；S4，夯机就位并根据由内而外，隔行跳打的原则对夯点位置进行强夯作业；S5，推土机将第一遍夯击时所形成的夯坑推平，并用标线放出第二遍夯点位置；然后按照S4中夯击作业的夯击方法和顺序将第二遍夯点全部夯击完成，强夯一遍后间歇一定时间；S6，进行满夯施工，夯击时，两个夯击点之间的夯印搭接1/4锤径夯击；S7，按照S3‑S6的施工方法对第一遍夯点和第二遍夯点再次夯击；S8，用压路机对夯击完成后的路基进行碾压。
