The 3000m barrier pool run is a combination of long-distance running and crossing obstacles. There are five hurdles on the runway, and the fourth hurdle has a pool. Throughout the entire process, we must overcome 15 obstacles, including seven crossing the pool. Today, Xiao Bian specifically stated how the 3,000-metre running obstacle pool was maintained.
The maintenance of the 3000m-meter barrier pool includes construction maintenance and maintenance.
The main point of maintenance during construction is the maintenance of the floor after cement concrete is poured. After the concrete is poured, it is better to use a large canvas to cover the obstacle pool, prevent the evaporation of water, prevent the sunlight from shining, and prevent wind and rain. After pouring 24, It can be maintained by means of watering to keep the floor moist. It is forbidden to fill the pool with water, because the concrete is not yet strong enough to bear the pressure of water.
Barrier pool maintenance in the use of the stage, when not in use, the use of wood cover to cover the entire pool, on the one hand to prevent personal injury, on the other hand to prevent surface heat after the summer sun exposure, sudden cooling after the rain caused shrinkage cracks. The most important thing is that before the arrival of each winter season, the water in the barrier pool should be cleared away, and the bottom and side walls of the barrier pool should be covered with straw curtains or rock wool, etc., in order to maintain the protection against freezing and freezing, because in the winter In the seasons, due to the temperature of the gas, the site has suffered from frost heave, which can often freeze the bottom of the barrier and the side walls. This is due to the loss caused by maintenance and is a lesson that has already occurred.
