Gravel-pebble permeable layer in fine sand layer and construction method thereof
The invention discloses a gravel-pebble permeable layer in a fine sand layer and a construction method thereof. The gravel-pebble permeable layer comprises a permeable layer, a gravel-pebble layer is bricked in the permeable layer, a water inlet pipe is arranged in the gravel-pebble layer, an isolating layer covers the top of the gravel-pebble layer, and the isolating layer is hermetically connected with the permeable layer. A foundation pit is excavated in a region which needs underground water replenishment, and the bottom of the foundation pit enters a fine sand aeration zone under the water seepage level; permeable material is paved on the side wall of the foundation pit, gravels and pebbles are paved and bricked, the water inlet pipe is paved, and the top surface of the gravel-pebble layer is higher than the water seepage level; the isolating layer covers the top surface of the gravel-pebble layer, fine sand covers the isolating layer to finish the construction of the gravel-pebble permeable layer, wherein the fine sand is parallel to the ground line. The gravel-pebble permeable layer enables the fine sand aeration zone to be converted into a water-bearing layer to ascend the underground water level to increase the water resource quantity for the water-bearing layer, the water resource quantity replenishment is realized for the underground water level descending region or when the underground water is polluted, and the underground water level is restored by a certain degree in a short time.
