Football field construction process

Abstract

The invention discloses a football field construction process. The football field construction process comprises following steps: 1, earth excavation and original soil ramming; 2, square grid laying;3, gradient adjusting; 4, sodium bentonite waterproofing carpet laying; 5, backfilling and soil ramming; 6, blind drain excavation and spraying water supply system installation; 7, graded broken stonelayer laying; 8, loess coarse sand layer laying; 9, planting soil coarse sand layer laying; and 10, natural grass layer plantation. When rain is too heavy, a double way water pump is turned on, rainin the blind drains and rain on football field surface are pumped into a spraying main pipe through a pipe network and nozzles, and is discharged into a water reservoir, so that football field draining speed is accelerated, and water accumulation of football fields is avoided. In drought days, water in the water reservoir can be conveyed into the pipe network, and sprayed onto lawn through the nozzles, so that water recycling is realized, water resource is saved. Under the action of single-way membrane, rainwater can be pumped into the pipe network, and flowing out from the pipe network is prevented, so that water and soil loss of a second base layer is reduced.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction technique for a football field. Background technique [0002] At present, the traditional football fields used in our country are prone to water accumulation or large-scale water accumulation when the weather is raining. If football players train or compete at this time, it will be difficult to train or compete due to accumulated water, which will affect football players. The play of the technical level will also increase the damage of the football field. [0003] The existing authorized announcement date is September 16, 2015, and the authorized announcement number is CN204644828U. This patent discloses a non-water-retaining football field, which includes a traditional football field. It is a non-water-retaining football field built on a hardened ground or foundation that is made of river pebbles that are bonded and rolled into a whole with many water seepage...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of this technical solution is: although it can effectively solve the problem that the traditional football field is easy to store water or store water in a large area when the weather is raining, when the water storage capacity of the irregular water seepage gap or void reaches saturation, it will still cause Accumulated water affects the technical level of football players; and because the seepage gap or gap is formed by bonding and rolling river pebbles, the seepage speed of the seepage gap or gap is relatively slow. Even when there is a lot of weather, it will still cause water accumulation
