Permeable dredger fill wharf yard pavement structure
The invention discloses a permeable dredger fill wharf yard pavement structure. The permeable dredger fill wharf yard pavement structure sequentially comprises a geocell permeable concrete layer, a geocell medium-coarse sand layer, a medium-coarse sand mattress layer and a PHC tubular pile cement-soil composite pile layer from top to bottom. A permeable mode is adopted, rainfall directly permeatesinto a foundation through geocell permeable concrete, and redundant moisture permeates into a drainage channel through horizontal permeation; and water in the foundation can move upwards through medium-coarse sands under the capillary action at high temperature, so that the surface temperature of the storage yard is reduced. compared with impermeable cement concrete, the pervious concrete on thesurface layer is less influenced by temperature change, so that the workload is reduced. Compared with wharf storage yards constructed through a traditional construction technology, the permeable dredger fill wharf yard pavement structure of the invention has the advantages of being small in post-construction settlement and differential settlement, capable of achieving self-drainage, low in construction cost, short in construction period, good in pavement integrity, free of cracking, long in service life, wide in application range and the like, and is suitable for construction of storage yardsof dredger fill or other soft soil foundations of inland river wharfs or harfs.
本发明公开了一种透水型吹填土码头堆场铺面结构，自上而下依次包括土工格室透水混凝土层、土工格室中粗砂层、中粗砂褥垫层和PHC管桩水泥土复合桩层。本发明采用透水模式，降水通过土工格室透水混凝土直接渗入地基中，多余的水分则通过水平渗透渗入排水通道；高温时地基中的水分会经由中粗砂通过毛细作用上移，进而降低堆场表面温度；本发明的表层透水混凝土与采用不透水的水泥混凝土相比，受温度变化的影响较小，减少了工作量。与传统码头堆场建设技术相比较，本发明具有工后沉降及差异沉降小、自排水、施工造价低、工期短、铺面整体性好、不开裂、服役寿命长、适用范围广等优点，适用于内河码头或海港码头的吹填土或其它软土地基的堆场建造。
