The well type for extracting shallow groundwater is also an ancient well type. Manual excavation is commonly used, with structures including well heads, shafts, inlet sections, and sediment settling sections, often constructed with bricks and stones or concrete pipes. The water inlet and sedimentation parts of the tube well and pipe well are mostly constructed with bricks and stones or concrete pipes. There is no strict difference between tube wells and pipe wells. The term 'tube well' is no longer used in the 'Technical Specification for Machine Wells' issued by China in 1986. ③ Big mouth well. A well type with a diameter generally ranging from 2 to 8 meters and a depth not exceeding 20 meters. ④ Radiation well. Composed of vertical collection wells and horizontal collection pipes (radiation pipes) radiating along the collection wells. Radiation tubes are often made of perforated steel or bamboo pipes. This well type is particularly suitable for water rich fine sand aquifers, loess aquifers, or clay fissure aquifers with poor water content.

As ground source heat pumps cover a wide range of areas, including the construction of air conditioning, shallow geothermal, and energy-saving industries, we need to fully consider these factors when analyzing their development prospects. At present, China's energy-saving industry is undergoing significant changes, shifting from the traditional coal-fired power utilization method to a diversified supply mode in various aspects. In this process, the use of geothermal energy is crucial. Geothermal energy has strong reliability and regeneration, and compared with wind and solar energy, there is no fluctuation or indirectness. Through the development and application of ground source heat pump wells, it can meet the increasing demand for cooling, heating, and hot water in China, and the application market is very promising. After analyzing the data from the Geothermal Conference, it is not difficult to find that the capacity and annual growth rate of ground source heat pump wells have exceeded our expectations, especially in the past 20 years, with a several fold increase rate. The growth rate has slowed down in the past 5 years. However, this does not mean that the ground source heat pump profession will decline in the future, but rather tend to develop towards a sustainable and benign direction. What is the installation of well casing like?

1 to 1.5 meters away from the foundation pit, with a spacing of 0.8 to 1.6 meters. Well point pipes are arranged at regular intervals around the foundation pit. A filter pipe is inserted into the permeable layer at the bottom of the well point pipe, and a flexible hose is connected to the water collection main pipe at the top. The water collection main pipe is made of φ 150 steel pipe, and a φ 40 suction pipe is set around the circumference with the same spacing as the well point pipe. The water in the water collection pipe is pumped out by a vacuum suction pump to reduce the groundwater level around the foundation pit and ensure that the base is dry and free of water. Water wells can be roughly divided into four categories: intact wells without pressure, incomplete wells without pressure, intact wells under pressure, and incomplete wells under pressure. In well point precipitation, the well point pipe (with a filter pipe at the bottom) and filter pipe are components of the well point pipe, used for filtering impurities from fine sand and silt formations in the well, to prevent these impurities from entering the precipitation pump and causing damage to the pump. Bridge filter pipes are produced using hot-rolled coils. The rolling process of the hot-rolled strip mill has a series of advantages and has the metallurgical process capability to produce high-quality pipeline steel. For example, a water cooling system is installed on the output rack to accelerate cooling, which allows the use of low-alloy components to achieve special strength levels and low-temperature toughness, thereby improving the weldability of steel.
