Method for filling dug well or waste pumping well with sand for recharging underground water and storing water

Abstract

The invention discloses a method for filling a dug well or a waste pumping well with sand for recharging underground water and storing water. According to the technical scheme, the new dug well or thewaste dry well is filled with sand to form a sand well, the mouth of the well is finished to be low, so that rainwater flows into the sand well, the rainwater permeates under the well along the gapsof the sand, the rainwater permeates into the soil when coming into contact with the soil in the well, namely, the recharge for the underground soil is realized, a water filtering column or a water filtering ball is reserved at the bottom of the well, one pipe is connected to the ground from the water filtering column or the water filtering ball, and when water is needed, a water pump is connectedfor pumping the water for use, namely, an underground water storage pool is formed.

Description

technical field [0001] The technology belongs to the field of pumping water from deep underground wells. technical background [0002] China's North China Plain is a semi-arid area. Many places have a high population density and a lot of farmland has been reclaimed. Due to the lack of rain, many years when the crops are in need of water, it does not rain every day. When it rains, this season's crops will be harvested by several percent. For many years, people used to dig wells to water, and used this method to make up for the water shortage of crops. Since the 1960s, more and more wells have been used to pump water, and the pumping has become more and more advanced. In the 1990s, the wells were drilled deeper and deeper. , The pumps are getting bigger and deeper, and as a result, many wells have no water and become abandoned wells. [0003] The media reported that a child fell into a 40-meter-deep dry well in Zhongmengchang Village, Lixian County, Hebei Province. More than ...

Problems solved by technology

But there are also many deficiencies. Water seepage pavement has only been developed in recent years. It is impossible to replace all pavement at once like Nanjing. At present, there are few small and medium-sized cities implementing water seepage pavement. Water seepage pavement relies on the gaps between stones, and water flows from the gaps Seep to the bottom, the dust and all kinds of garbage on the ground will slowly block the gaps over time, and the seepage speed of the seepage road will gradually decrease over time. In addition, the water seeping from the seepage road will have some impact on the subgrade. At present, only the roads paved on sidewalks, high-grade highways, and roads with tens of tons or hundreds of tons of vehicles have not used water seepage pavement.
