The invention relates to the technical field of roadbed frost boiling treatment, and discloses a construction scheme for sealing a foundation bed to achieve thorough roadbed frost boiling treatment, which comprises the following steps: carrying out sleeper drawing and sleeper squaring according to requirements, carrying out ballast bed excavation by an excavator, carrying out foundation bed excavation, replacing new ballasts on the whole section of the line, washing the stone ballasts with water, and carrying out cleaning and transportation on dirty ballasts after the ballast bed is replaced. Four thick gravel cement layers are laid on the surface layer of the foundation bed, and each thick gravel cement layer is 5 cm thick. The four gravel cement layers are arranged, the waterproof viscose cloth is laid among the four gravel cement layers, multiple waterproof layers can be formed, compared with a traditional waterproof layer, the waterproof effect is improved, water is prevented from entering the roadbed, the anti-condensation cotton plate is arranged on the surface of the waterproof viscose cloth, water can be actively absorbed, and the waterproof effect is improved. And the water can be automatically discharged from the side surface after being saturated by absorbing water, so that automatic drainage is realized, and subgrade frost boiling is avoided.
本发明涉及路基翻浆整治技术领域，公开了一种封闭基床以达到彻底整治路基翻浆的施工方案，包括以下步骤：按要求进行抽枕、方枕，挖掘机进行道床、基床清挖，对本段线路全断面换新砟，石砟采用水洗道砟，对道床更换后的污砟进行清运，基床表层铺设四层厚碎石水泥层，每层厚碎石水泥层为5cm。本发明通过设置四层碎石水泥层，并在四层碎石水泥层之间铺设防水粘布，能够形成多层防水层，比起传统防水层提升了防水的效果，避免了水进入到路基内部，而且在防水粘布表面设置有防凝露棉板，不仅能够主动式的进行吸水，而且在吸水饱和后能够自动从侧面排出，从而自动排水，避免了路基翻浆。
