[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] A pump house located in a mountainous area, which is located above the pump well 4 and is combined with Figures 1 to 2 As shown, it includes a pump house 1, a ring beam 101, a foundation pit 2, a cover plate 3, a pump well 4, a steel plate 41, a header pipe 5, a PE pipe 511, a submersible pump 6, a temperature sensor 7, a PLC controller 8, and a heater 9. The header pipe 5 includes a right-angle elbow 51, an inlet and outlet valve 52, a rubber flexible joint 53, a straight pipe 54, a pressure gauge 55, a check valve 56, a butterfly valve 57, an electromagnetic flowmeter 58, a reducer 59, and a through-wall steel pipe 510.

[0018] Ring beams 101 are provided at the top and bottom of the pump room 1. The ring beams 101 are made of reinforced concrete to enhance the overall rigidity and the bending and vibration resistance of the wall, and to prevent the adverse effects of uneven foundation settlement or large vibration loads on the pump room 1.

[0019] Pump house 1 is 3.2m high, 0.24m thick, and has a 0.1m thick fine stone concrete floor. The foundation of pump house 1 adopts a brick-concrete strip foundation, and the foundation of pump house 1 is buried 1.5m deep and 0.8m wide.

[0020] The inner and outer walls of pump house 1 are plastered with 20mm thick cement mortar. The outer wall of pump house 1 is painted with yellow paint, and the inner wall is painted with white mortar.

[0021] A foundation pit 2 is excavated below the ground at the bottom of pump house 1, located above the pump shaft 4. The walls of pit 2 are a brick-concrete structure, 0.24m thick, and finished with M10 mortar. A reinforced concrete cover 3 is installed on the top of pit 2, and a concrete cushion is placed at the bottom.

[0022] A steel plate 41 is provided at the top of the well 4 for sealing the well. A submersible pump 6 is provided in the well 4, and the submersible pump 6 is connected to a header pipe 5 provided in the foundation pit 2. The header pipe 5 includes a right-angle elbow 51 connected to the submersible pump 6, and an inlet and outlet valve 52 is provided on the right-angle elbow 51. The inlet and outlet valve 52 is connected to a rubber flexible joint 53, which is connected to a straight pipe 54. The straight pipe 54 is provided with a pressure gauge 55, a check valve 56, a butterfly valve 57, and an electromagnetic flowmeter 58 in sequence. The outlet end of the straight pipe 54 is connected to a reducer 59 via a flange. The reducer 59 is connected to a through-wall steel pipe 510 that passes through the wall of the foundation pit 2, and the through-wall steel pipe 510 is connected to a PE pipe 511.

[0023] A temperature sensor 7 for detecting the temperature in the foundation pit 2 is provided in the foundation pit 2, and an output end of the temperature sensor 7 is connected to a PLC controller 8. An output end of the PLC controller 8 is connected to a heater 9, and the PLC controller 8 is connected to a power supply.

[0024] During actual use, the submersible pump 6 draws water from the well 4, which then flows through the header pipe 5 and out of the pump room. The header pipe is located in a subsurface foundation pit, where the temperature is higher than the ground, effectively preventing equipment from freezing. If the temperature drops below a set point, the temperature sensor 7 sends a signal to the PLC controller, which controls the heater 9 to heat the pit, ensuring that the temperature does not drop too low and the equipment operates normally. When maintenance is required, personnel enter the pump room and open the cover 3 to perform maintenance.
