Utility tunnel resistant to gas explosion
The invention discloses a utility tunnel resistant to gas explosion and relates to the technical field of utility tunnels. The utility tunnel comprises a gas cabin, a low-risk cabin and a comprehensive cabin. The low-risk cabin is adjacent to the gas cabin. The comprehensive cabin is arranged on the upper side of the low-risk cabin. The outline of a section of a connecting node for the gas cabin,the low-risk cabin and the comprehensive cabin is in the shape of a cross. By taking the design position of the gas cabin into reasonable consideration and by optimizing gravity and structure, the gasexplosion resistance of the utility tunnel is improved through the cross-shaped outline of the section of connecting node, it can be guaranteed that partition plates inside the cabins are not damagedwhen mild gas explosion occurs, the safety of the comprehensive cabin can be still guaranteed when explosion in extreme situations occurs, the safety of gas access to the tunnel is improved, the construction and operation cost is lowered on the premise that the gas explosion resistance is improved when compared with a gas cabin built by adopting a special structure, smooth implementation of the gas access policy for the tunnel is promoted, and application and popularization are facilitated.
本发明公开了一种抗燃气爆炸的综合管廊，涉及综合管廊技术领域，包括燃气舱室、低风险舱室、综合舱室，低风险舱室与燃气舱室相邻，综合舱室设于低风险舱室的上侧，燃气舱室、低风险舱室与综合舱室的连接节点的断面外形呈十字形，通过对燃气舱室的设计位置进行合理考虑，利用重力和结构上的优化，通过十字形连接节点的断面外形提高了综合管廊的抗燃气爆炸能力，发生轻度燃气爆炸时，能够保证舱室内隔板不发生破坏，发生极端情况的燃气爆炸时，仍能够保证综合舱室的安全，增加了燃气入廊的安全性，在提高抗燃气爆炸能力的前提下，相较于采取特殊构造建设的燃气舱室而言，建设和运营成本降低，利于推动燃气入廊政策的顺利实施，利于推广使用。
