Coal conveying belt conveyor trestle deformation joint and construction method thereof
The invention discloses a coal conveying belt conveyor trestle deformation joint and a construction method thereof. The trestle deformation joint sequentially comprises a bottom layer, a top layer, a bottom layer and a top layer from bottom to top, wherein the bottom layer is a U-shaped pocket made of two-cloth eight-coating LEAC acrylic polymer cement waterproof coating impregnated native polyester fiber reinforced cloth; the thermal insulation layer comprises a rubber surface filled in the deformation joint and a waterproof coating emulsion poured in a gap between the rubber surface and the deformation joint; the waterproof layer comprises a two-cloth eight-coating LEAC acrylic polymer cement waterproof coating layer and an LEAC waterproof emulsion layer; the protective layer is made of aluminum foil glass fabric or a steel plate with the same width as the deformation joint. It can be guaranteed that the waterproof layer has enough binding power and certain flexibility, deformation can be achieved along with a floor and a deformation joint, damage is avoided during large deformation due to enough stretching and twisting strength, and the waterproof layer can return to the original position after deformation is recovered due to enough elasticity; the performance is not obviously changed under the action of vibration load and temperature of the next year due to sufficient fatigue resistance.
本发明公开了一种输煤皮带机栈桥变形缝及其施工方法，该栈桥变形缝从下往上依次包括：底层，采用由两布八涂LEAC丙烯酸聚合物水泥防水涂料浸渍原生聚酯纤维加筋布制成的U型兜；保温层，包括填充在变形缝内的橡胶面，以及灌注在橡胶面与变形缝之间间隙内的防水涂料乳液；防水层，包括两布八涂LEAC丙烯酸聚合物水泥防水涂料层和LEAC防水乳液层；保护层，采用与变形缝同宽的铝箔玻纤布或钢板。本发明能够保证防水层具有足够的粘结力和一定的柔性，可伴随楼面、变形缝的变形、足够的拉伸及扭曲强度在大变形时不发生破坏，足够的弹性在变形恢复后能回到原位，足够的抗疲劳性在振动荷载及年复一年的温度作用下性能不发生显著改变。
