Tropical zone roadbed settlement treatment method
The invention discloses a tropical zone roadbed settlement treatment method. The method comprises the steps of: inserting a plurality of first water seepage pipes into a soft soil foundation, and extending the lower ends of the first water seepage pipes into the soft soil foundation; laying a concrete layer on the soft soil foundation, arranging a drainage pipe in the concrete layer, wherein the drainage pipe comprises two drainage pipe sections and each drainage pipe section obliquely extends downwards, extending the outer ends of the drainage pipe sections to the positions of side slopes ontwo sides of the concrete layer, and connecting the upper ends of the first water seepage pipes with the drainage pipe; laying a graded gravel layer on the concrete layer, disposing a plurality of second water seepage pipes in the graded gravel layer, extending the lower ends of the second water seepage pipes into the concrete layer, and connecting the second water seepage pipes with the drainagepipe; digging two drainage ditches in the two sides of the concrete layer, and making the outer side ditch walls of the drainage ditches lower than the drainage pipe. The drainage effect of the foundation and the interior of the roadbed can be improved, and then differential settlement of the roadbed in the tropical zone is reduced.
本发明公开了一种热带地区路基沉降处治方法，包括：在软土地基内插设多个第一渗水管，第一渗水管的下端延伸至软土地基的内部；在软土地基的上方铺设混凝土层，在混凝土层的内部设置排水管，排水管包括两个排水管段，每个排水管段倾斜向下延伸，排水管段的外端部延伸至混凝土层的两侧边坡位置，将第一渗水管的上端与排水管连接在一起；在混凝土层上方铺设级配砂石层，在级配砂石层的内部设置多个第二渗水管，第二渗水管的下端延伸至混凝土层内部，将第二渗水管与排水管连接在一起；在混凝土层的两侧挖设两条排水沟，且排水沟的外侧沟壁高度低于排水管的高度。本发明可以改善地基以及路基内部的排水效果，进而减少热带地区路基的不均匀沉降。
