Fabricated recycled aggregate cement concrete plate structure and construction method
The invention relates to the technical field of assembly type cement concrete construction, and provides an assembly type recycled aggregate cement concrete plate structure and a construction method.The recycled aggregate cement concrete plate structure is formed by splicing a plurality of foundation plates or semi-foundation plates; and the side plates of the basic plate blocks or the semi-basic plate blocks are inserted into the grooves of the adjacent basic plate blocks or the semi-basic plate blocks to form mortise and tenon joint structure connection. The invention further provides a construction method, the soft soil foundation is treated in advance, the water content of the roadbed is reduced, and the shear strength of the roadbed is enhanced; according to the connection mode between the base plates, the shear stress and the bottom tensile stress of the pavement are reduced, and the cement concrete pavement has high bending tensile strength. The cement concrete pavement has high extensibility by utilizing the preformed hole structures of the side plates, the driving load can be better decomposed and transmitted to other concrete plates, the risk of cracks is effectively avoided, and the maintenance cost during operation is reduced.
本发明涉及装配式水泥混凝土施工技术领域，提供一种装配式再生骨料水泥混凝土板块结构及施工方法，再生骨料水泥混凝土板块结构由若干基础板块或半基础板块拼接而成，基础板块或半基础板块的边板插入相邻基础板块或半基础板块的凹槽，形成榫卯结构连接。本发明还提供一种施工方法，事先对软土地基进行处理，降低路基含水率、增强路基的抗剪强度；本发明基础板块间的连接形式，降低了路面的剪应力以及底部拉应力，使水泥混凝土路面具备较强的抗弯拉强度。利用边板的预留孔结构使得水泥混凝土路面具有较强的延伸性，能够更好的将行车荷载分解并传递到其他混凝土板块，有效规避出现裂缝的风险，降低了运营期间的维护成本。
