Research on One-Time Pouring Technology of Tunnel Indoor Fire Pool
With the rapid development of tunnel engineering technology,multi-purpose tunnel facilities have appeared.The fire pool,as an important building to prevent fire hazards in the tunnel,its construction quality is particularly important,usually the tunnel floor is served as fire pool floor,and the tunnel lining,end wall and partition wall are used as side walls.However,as a water storage structure,the fire pool has high requirements for waterproof.It is necessary to pour the floor and side walls simultaneously during construction to ensure the integrity of the fire pool structure.But in construction,due to the limitation of space,existing construction technology cannot achieve one-time pouring.By setting up scaffolding twice,building transverse supports on the floor reinforcement,a support system frame was researched to realize one-time pouring fire pool,which successfully solved the construction safety,quality,duration,environmental protection,cost and a series of problems of the fire pool.Through extensive engineering practice,it has been proven that the construction technology that has been formed is becoming increasingly mature and perfect,which has a significant effect on ensuring the stability and control of the quality of the tunnel indoor fire pool.This can provide reference and inspiration for the construction of fire pool in similar tunnels in the future.
