Horizontal hollow pipe landfill vibration isolation barrier and construction technology thereof
The invention discloses a horizontal hollow pipe landfill vibration isolation barrier and a construction technology thereof. The horizontal hollow pipe landfill vibration isolation barrier is composed of concrete hollow pipes (1) and clay (2) backfilled and compacted around the concrete hollow pipes (1). The construction technology comprises the steps that during environmental vibration isolation engineering, firstly, a groove is excavated under a steel sheet pile enclosure structure, concrete hollow pipe joints are hung in the groove in a layered mode after excavation is finished, after each layer of pipe joint is hung, soil is backfilled on the upper part of the pipe joint and compacted into a pipe base matched with the radian of a pipe body, then the upper layer of pipe joint is placed, and the whole groove is filled with the concrete hollow pipe joints and the clay; and a certain angle is formed between a plane formed by connecting the center lines of the upper and lower concrete hollow pipes and the horizontal plane. By adjusting the embedding inclination angle alpha of the upper-layer hollow pipe and the lower-layer hollow pipe and the radial distance between the upper-layer hollow pipe and the lower-layer hollow pipe, the vibration isolation effect of the vibration isolation barrier can be further optimized, and better vibration isolation performance is achieved on the premise that cost is not increased.
一种水平空心管填埋隔振屏障及其施工工艺，所述水平空心管填埋隔振屏障由混凝土空心管（1）及其周围回填压实的黏土（2）组成。所述施工工艺在用于环境隔振工程时，先在钢板桩围护结构下进行沟槽的开挖，开挖结束后在沟槽内分层吊放混凝土空心管节，每层管节吊放完成后在其上方回填土体并压实成与管身弧度相适应的管座再安防上一层管节，直至整个沟槽被混凝土空心管节和黏土填满为止；上下层混凝土空心管中心线连线构成的平面与水平面之间成一定角度。本发明通过调整上下层空心管的埋设倾角α以及上下空心管之间的径向间距，能够进一步优化该隔振屏障的隔振效果，在不增加成本的前提下实现更好的隔振性能。
