The invention discloses a foundation reinforcement construction method which comprises the following steps: S100, determining the area of a to-be-reinforced foundation, and investigating the peripheral area of the to-be-reinforced foundation; s200, the surveying range of the foundation to be consolidated is delimited; s300, determining whether tamping is needed or not according to the survey result, executing the step S400 when tamping is needed, and executing the step S500 when tamping is not needed; s400, dynamic compaction is conducted in three times, point compaction is conducted in the first two times, and full compaction is conducted in the last time; and S500, grouting pipes are arranged on the ground surface of the to-be-reinforced ground, gravels are poured into the grouting pipes, cement paste is injected after the grouting pipes are pulled out, gravel piles are formed, and a foundation reinforcing structure is formed. According to the method, the to-be-reinforced foundation is surveyed, the foundation information is obtained, compaction reinforcement or compaction and gravel pile reinforcement are selected according to the actual survey result, the foundation strength is effectively improved, foundation collapse is avoided, the construction method is rapid and simple, and the construction quality can be effectively guaranteed.
本发明公开了一种地基加固施工方法，包括以下步骤：S100、确定待加固地基的面积，对待加固地基周边区域进行勘察；S200、划定待加固地基的勘测范围；S300、根据勘测结果确定是否需要进行夯实，需要夯实时进行步骤S400，不需要夯实时进行步骤S500；S400、分三遍进行强夯，前两遍为点夯，最后一遍进行满夯；S500、在待加固地基地面上布设注浆管，向注浆管中灌入碎石，拔出注浆管后注入水泥浆形成碎石桩，形成对地基加固结构。本发明通过对待加固地基进行勘测，获取地基信息，从而根据实际勘测结果选择夯实加固或夯实结合碎石桩加固，有效提高地基强度，避免地基坍塌，而且施工方法快速简便，施工质量能得到有效保证。
