Inverted trapezoidal pile vibration isolation barrier and construction method thereof
The invention relates to the technical field of vibration reduction on a propagation path, in particular to an inverted trapezoidal vibration isolation barrier and a construction method thereof, and the inverted trapezoidal vibration isolation barrier is arranged on the propagation path between a vibration source and a vibrated object. The barrier is mainly composed of concrete, a stable vibration isolation groove can be dug in the middle of the barrier, and soft filler filling or soft and hard material alternate filling can be further carried out in the groove. According to the construction method, the step-shaped groove is excavated firstly and then poured and filled, or the jet grouting pile is adopted for construction, and the section width is controlled through the lifting speed and the injection pressure of the drill rod. The inverted trapezoidal vibration isolation barrier is constructed by making full use of the propagation rule (the characteristic of large proportion of surface wave energy near the earth surface) of vibration waves in a soil body, the difficulty of trench excavation is reduced, filling materials are saved, and the efficient filling trench vibration isolation barrier is formed. The method is used for controlling environment vibration caused by traffic, construction and the like.
本发明涉及在传播路径上减振技术领域，具体涉及倒梯形隔振屏障及其施工方法，在振源与受振物体之间的传播路径上设置倒梯形隔振屏障。该屏障主要由混凝土构成，屏障中间可挖成稳定的隔振沟槽，进一步可在沟槽内进行软填充料填充或软、硬材料交替填充。施工方法可采用先开挖阶梯型沟槽后浇筑填充，或采用旋喷桩施工，通过钻杆提升速度和喷射压力控制截面宽度。本发明充分利用振动波在土体中的传播规律(近地表的面波能量占比大的特点)，构筑倒梯形隔振屏障，降低开挖沟槽的难度，节省了填充材料，形成高效的填充沟隔振屏障。本发明用于交通、施工等引起的环境振动控制。
