The invention relates to the technical field of railroad bed diseases, and discloses a construction process for treating railroad bed diseases by adopting subgrade bed sealing and subgrade body grouting, which comprises the following steps: step 1, carrying out sleeper drawing and square sleeper digging according to requirements, carrying out ballast bed and subgrade bed clearing and digging by using an excavator, and paving thick gravel cement layers at two ends of a subgrade bed and on the surface layer of the subgrade bed, and super absorbent resin and silica gel desiccant are mixed in the thick gravel cement layer. The water absorption stone cement layer is laid on the top of the thick gravel cement layer, water can be rapidly absorbed through the loose and porous structure of the water absorption stone cement layer and is discharged from the side face of the foundation bed through the water outlet pipe, and accumulation of the water in the foundation bed is avoided; the super absorbent resin and the silica gel desiccant can be used for improving the water absorption performance of the thick gravel cement layer, and after water absorption of the silica gel desiccant is completed, moisture in the silica gel desiccant can be evaporated through high temperature, so that the silica gel desiccant can be repeatedly used.
本发明涉及铁路路基病害技术领域，公开了一种采用基床封闭及路基本体注浆处理铁路路基病害的施工工艺，包括以下步骤：步骤一：按要求进行抽枕、方枕，挖掘机进行道床、基床清挖，并在基床两端和基床表层铺设厚碎石水泥层，在厚碎石水泥层内部掺混有超吸水树脂和硅胶干燥剂。本发明通过在厚碎石水泥层顶部铺设吸水石水泥层，可以利用吸水石水泥层疏松多孔的结构，将水快速吸收，并经过出水管从基床侧面排出，避免了水在基床内部堆积，在厚碎石水泥层内部掺混有超吸水树脂和硅胶干燥剂,可以利用超吸水树脂和硅胶干燥剂增加厚碎石水泥层的吸水性能，而且硅胶干燥剂在吸水完成后，经过高温能够将内部的潮气蒸发，使硅胶干燥剂能够重复使用。
