Novel tunnel portal external expansion type open cut tunnel protection structure
The invention discloses a novel tunnel portal external expansion type open cut tunnel protection structure which comprises an arched open cut tunnel, a protection blocking edge and a foundation supporting part, one end of the arched open cut tunnel is a vertical cutting type portal, the other end of the arched open cut tunnel is an inclined cutting type portal, the upper end of the inclined cutting type portal inclines towards one side of the vertical cutting type portal, and the protection blocking edge is obliquely arranged at one end of the inclined cutting type portal of the arched open cut tunnel. The foundation supporting part is arranged at the lower ends of the arched open cut tunnel and the protective blocking edge; the arched open cut tunnel expands outwards in an arc shape from one end of the vertical cutting type hole to one end of the inclined cutting type hole, the inner wall of the protective blocking edge is flush with the inner wall of the arched open cut tunnel, the inner wall of the protective blocking edge expands outwards in an arc shape from one end close to the arched open cut tunnel to one end away from the arched open cut tunnel, and the wall thickness of the protective blocking edge is gradually reduced from the middle to the two ends. According to the open cut tunnel protection structure, the tunnel portal can be effectively protected, meanwhile, airflow generated at a high speed can be guided and discharged, and therefore noise is effectively reduced.
本发明公开了一种新型隧道口外扩型明洞防护结构，包括拱形明洞、防护挡沿和基础支撑部，拱形明洞的一端为竖切式洞口、另一端为斜切式洞口，斜切式洞口的上端向竖切式洞口一侧倾斜，防护挡沿倾斜设置在拱形明洞的斜切式洞口一端，基础支撑部设在拱形明洞和防护挡沿的下端；拱形明洞从竖切式洞口一端向斜切式洞口一端呈弧形向外扩张，防护挡沿的内壁与拱形明洞的内壁平齐，防护挡沿的内壁由靠近拱形明洞一端向远离拱形明洞一端呈弧形向外扩张，防护挡沿的壁厚由中部向两端逐渐减小。本发明的明洞防护结构不仅可以对隧道口起到有效的防护作用，同时还可以对高速产生的气流起到导向外排作用，从而有效减少噪音的产生。
