Disease road single-hole composite grouting reinforcement base layer and roadbed construction method
The invention relates to the technical field of road grouting, in particular to a construction method for reinforcing a base layer and a roadbed through single-hole composite grouting of a diseased road, and the construction method comprises the following steps: step 1, selecting a cement-based grouting material, and designing a grouting process and an acceptance index after grouting according to the disease type of the base layer and the roadbed and a grouting reinforcement target; 2, according to the technical requirements of the cement-based grouting material, proper raw materials are selected, the mixing proportion of grouting liquid is designed, the grouting liquid is injected into one filling barrel, and the other filling barrel is filled with water; 3, grouting design parameters are determined, wherein the grouting design parameters comprise the grouting pressure, the hole diameter and the hole distance. According to the grouting device, soil in the grouting pipe can be sent out from the top end of the connecting pipe through rotation of the auger, so that the situation that holes in the outer wall of the grouting pipe are blocked by excessive soil in the grouting pipe is prevented, and the grouting efficiency of a base layer and a foundation can be improved.
本发明涉及道路注浆技术领域，具体是病害道路单孔复合注浆加固基层和路基施工方法，该施工方法包括如下步骤：步骤一：根据基层和路基的病害类型和注浆加固的目标，选择水泥基注浆材料，设计注浆工艺和注浆后的验收指标；步骤二：根据水泥基注浆材料的技术要求，选择合适的原材料，并设计注浆液的配合比，将注浆液注入其中一个灌装桶内，另一个灌装桶内灌装水；步骤三：确定注浆设计参数，包括注浆压力、孔径直径和孔距。本发明中，该装置通过绞龙的转动可以将注浆管内的泥土从连接管的顶端送出，因此防止注浆管内的泥土过多而将注浆管外壁的孔堵住，从而可以提高对基层和地基的灌浆的效率。
