Bridge leveling layer, bridge and construction method
The invention discloses a bridge leveling layer, a bridge and a construction method, and the leveling layer comprises a hybrid fiber concrete layer which is arranged on the top surface of each beam plate; the at least one high-ductility cement-based composite material layer is used for being arranged at the interval position of the adjacent beam plates and is embedded into the hybrid fiber concrete layer from the top face of the hybrid fiber concrete layer, and the width of the high-ductility cement-based composite material layer is larger than the width of the interval between the two corresponding beam plates. The bridge leveling layer comprises the hybrid fiber concrete layer, internal fibers of the hybrid fiber concrete layer have high homogeneity, and therefore a reinforcing mesh in a traditional leveling layer can be omitted; in addition, the high-ductility cement-based composite material layer is arranged in the hogging moment area of the bridge, and large cracks can be avoided. The hybrid fiber concrete layer and the high-ductility cement-based composite material layer are used for replacing a traditional leveling layer, the characteristics of low shrinkage rate and high crack resistance are achieved compared with the traditional leveling layer, shrinkage cracking of the leveling layer can be reduced, and the service life is prolonged.
本申请公开一种桥梁整平层、桥梁，及建造方法，该整平层包括:混杂纤维混凝土层，用于设于各梁板的顶面；至少一个高延性水泥基复合材料层，用于设于相邻梁板的间隔位置处，且从混杂纤维混凝土层的顶面嵌入至混杂纤维混凝土层内，高延性水泥基复合材料层的宽度大于其对应的两梁板之间的间隔宽度。本申请中的桥梁整平层，包括混杂纤维混凝土层，其内部纤维具有较高的均质性，故而可以取消传统整平层中的钢筋网片；另外在桥梁的负弯矩区设置高延性水泥基复合材料层，可以避免产生大裂纹。利用混杂纤维混凝土层和高延性水泥基复合材料层，代替传统的整平层，相比之下具有低收缩率和高抗裂的特性，能够降低整平层收缩开裂的出现，提高使用寿命。
