Roadbed construction method of peat soil foundation
The invention provides a roadbed construction method of a peat soil foundation. The roadbed construction method comprises the following steps of an acquiring step, specifically, acquiring the optimalwater content value of sea sand in the maximum dry density state; a laying step, specifically, laying the sea sand on the peat soil foundation; a watering step, watering the sea sand to a preset degree; a rolling step, specifically, rolling the watered sea sand; and a detecting step, specifically, detecting whether the compaction degree of the rolled sea sand meets the preset standard or not, determining the preset standard according to the optimal water content value, and if the compaction degree of the rolled sea sand does not meet the preset standard, repeating the watering step, the rolling step and the detecting step till the compaction degree of the rolled sea sand meets the preset standard. By means of the roadbed construction method, the roadbed construction quality of the peat soil foundation can be effectively guaranteed, the construction difficulty is lowered, and the construction progress is accelerated; in addition, the sea sand is used for filling, especially in coastal areas rich in sea sand resource, resources can be effectively utilized, and the engineering cost is saved; and according to the method, static pressure is only needed once, repeated rolling is not needed, and the construction steps and the engineering cost are saved.
本发明提供了一种泥炭土地基的路基施工方法，该方法包括如下步骤：获取步骤，获取海砂在最大干密度状态下的最佳含水率值；铺设步骤，将海砂铺设于泥炭土地基；洒水步骤，对海砂进行洒水至预设程度；碾压步骤，对洒水后的海砂进行碾压；检测步骤，检测碾压后的海砂的压实度是否满足预设标准；其中，预设标准根据最佳含水率值确定；若不满足预设标准，重复洒水步骤、碾压步骤和检测步骤直至满足预设标准为止。本发明能有效地保证泥炭土地基的路基施工质量，降低了施工难度，加快了施工进度，并且利用海砂填筑，尤其是沿海海砂资源丰富的地区，能有效利用资源，节省工程成本，该方法只需静压一次即可，无需多次碾压，节省了施工步骤和工程造价。
