Description

Technical Field

[0001] This application relates to the field of foundation treatment in civil engineering, and in particular to a solar-air energy complementary intelligent heating consolidation construction system and method. Background Technology

[0002] In some regions, soft soil strata with high compressibility, low permeability, and low strength are widely distributed. Improper foundation treatment in these areas can lead to excessive or differential settlement, causing serious engineering quality problems. Currently, the common method for soft soil foundation treatment is to install vertical wells leading to drainage wells to accelerate soil consolidation. However, this method suffers from smearing and well resistance effects, slowing down the consolidation rate. To address this issue, some researchers have explored heating to increase the permeability of the soft soil around the wells, thereby accelerating consolidation. Studies show that thermal drainage consolidation can achieve better consolidation results within the same timeframe, accelerating settlement. However, conventional electric heating leads to significant energy consumption and increased costs, and also poses certain safety hazards. Summary of the Invention

[0034] In another exemplary embodiment of this application, please refer to Figure 3The air source heat pump heating device 2 includes an evaporator 15, a compressor 16, a condenser 17, and an expansion valve 18 connected in sequence. The evaporator 15 is connected to the hot water storage tank 14; the expansion valve 18 is connected to the evaporator 15; the condenser 17 is connected to the insulated water tank 3; the evaporator 15 is used to absorb heat energy provided by the solar collector 1 or to obtain heat energy from the air, thereby converting the liquid medium into a gaseous medium, and the evaporator 15 can be an air-cooled evaporator; the compressor 16 is used to pressurize and heat the gaseous medium; the condenser 17 is used to exchange heat between the pressurized and heated gaseous medium and the hot water drawn from the drain plate 4 into the insulated water tank 3, thereby heating the hot water to a set temperature and converting the pressurized and heated gaseous medium into the liquid medium; the expansion valve 18 is used to allow the liquid medium in the condenser 17 to flow back to the evaporator 15.

[0035] The working principle of the air source heating device 2 in this embodiment is as follows: a compressor 16 draws in a low-temperature, low-pressure gas medium, compresses it into a high-temperature, high-pressure gas medium through mechanical movement, and a condenser 17 causes the high-temperature, high-pressure gas medium to release heat energy which is absorbed by the cooled liquid medium to obtain a high-pressure liquid medium. An expansion valve 18 adjusts the high-pressure liquid medium to a low-pressure liquid medium so that it can enter the evaporator 15.

[0037] In another exemplary embodiment of this application, the solar-air energy complementary intelligent heating consolidation construction system further includes: a vacuum pre-compression pump 5; the vacuum pre-compression pump is connected to the system control device 7; the system control device 7 is also used to control the vacuum pre-compression pump to extract air from the target soil 24, so that the water in the target soil 24 is discharged through the drainage plate 4.

[0038] In another exemplary embodiment of this application, the temperature measuring device 6 includes a temperature sensor.

[0039] In another exemplary embodiment of this application, the drainage board 4 may be a heated plastic drainage board 4.

[0040] In another exemplary embodiment of this application, the solar-air energy complementary intelligent heating consolidation construction system further includes: a sand cushion layer 22, woven fabric, geotextile, and sealing membrane. The sand cushion layer 22 is disposed on the surface of the target soil 24, and the sand cushion layer 22 is used to assist the drainage of hot water in the drainage board 4. In practical applications, in order to improve the stability and safety during foundation construction, the system is placed on the surface of the foundation that needs to be reinforced, with the sand cushion layer 22 laid first, followed by the pipes, and then the woven fabric, geotextile, and sealing membrane laid in sequence.

[0041] In practical applications, a more specific deployment process of the solar-air energy complementary intelligent heating and consolidation construction system is as follows: Drainage boards 4 in both forward and reverse directions are inserted in the heating and consolidation drainage area. After completion, a sealing trench is set up around the installation. Vacuum branch pipes are laid parallel to the drainage boards 4. The drainage boards 4 are connected to the vacuum branch pipes using hand-shaped plate heads. The vacuum main pipe 23 is arranged perpendicular to the vacuum branch pipes. A reducing tee or four-way valve is used to connect the vacuum branch pipes and the vacuum main pipe 23. The solar collector 1, air energy heating device 2, and insulated water tank 3 are connected in series. The outlet of the insulated water tank 3 is connected to the hot water pipe 21 and the inlet of the drainage board 4 in sequence. The inlet of the air energy heating device is connected to the solar collector 1. The hot water in the drainage board 4 is extracted by the circulating water pump 19 and transported into the insulated water tank 3, where it is heated by the air energy heating device 2. Woven fabric, geotextile, and sealing membrane are laid sequentially in the heated consolidation and drainage zone. Air is extracted from the target soil 24 using a vacuum pre-pressure pump 5, and water in the target soil 24 is discharged through the drainage board 4. This combines new clean energy with thermal drainage consolidation technology, which improves the rate of foundation consolidation, while being energy-saving, environmentally friendly, and low-cost.

[0042] The solar-air energy complementary intelligent heating and consolidation construction system is controlled by the system control device 7. The system control device 7 can decide whether to pump back some of the lower-temperature hot water in the drainage board 4 based on parameters such as soil temperature and sunlight conditions in different heating and consolidation drainage areas. It can also decide whether to heat the additional cold water based on the hot water level in the insulated water tank 3. For example, after the hot water in the drainage board 4 is replenished and the pumped hot water has been heated and transported to the drainage board 4, if the hot water level in the insulated water tank 3 does not reach the set level (e.g., 75%), the cold water valve in the insulated water tank 3 is opened to replenish the cold water and heat it to achieve the purpose of replenishing the hot water in the insulated water tank 3. When it is sunny or there is sufficient sunlight during the day, the solar power generation device 10 stores the obtained electrical energy in the electrical energy storage device 11. When it is cloudy or there is insufficient sunlight at night, the air energy heating device 2 will give priority to using the electrical energy in the electrical energy storage device 11. If the electrical energy in the electrical energy storage device 11 is exhausted, the external power supply 12 is used to maintain the operation of the heating system.

[0043] The drainage board 4 in the solar-air energy complementary intelligent heating and consolidation construction system can include multiple hot water pipes, for example, five hot water pipes (which can be adjusted according to actual conditions) can be laid in a heating and consolidation drainage area. The five hot water pipes are connected to a hot water supply pipe 21. A temperature measuring device 6 is installed in a heating and consolidation drainage area. The temperature measuring device 6 feeds back the soil temperature of each heating and consolidation drainage area to the system. When the soil temperature of a certain heating and consolidation drainage area is lower than 45°C, all the hot water in the drainage board 4 in that heating and consolidation drainage area is extracted and new hot water is added.

[0044] The arrangement of drainage boards 4 in the heated consolidation drainage zone can be designed based on the numerical simulation calculation results. By inputting the stratum information of the heated consolidation drainage zone, a more optimized drainage consolidation scheme can be obtained. For soils with low thermal conductivity, the drainage boards 4 are arranged more densely, while for soils with high thermal conductivity, the drainage boards 4 are arranged more sparsely. At the same time, the drainage consolidation effects of triangular arrangement, rectangular arrangement, different heating temperatures, and different spacing of drainage boards 4 can be compared to optimize the arrangement scheme of drainage boards 4.

[0045] The solar-air energy complementary intelligent heating and consolidation construction system also detects pore water pressure to calculate the degree of consolidation of the soil in the heating and consolidation drainage zone. When the degree of consolidation reaches 90% or more, heating is stopped and a notification is issued. The calculation process is as follows: first, the initial excess pore water pressure is subtracted from the detected pore water pressure to obtain the difference, and then the difference is divided by the initial excess pore water pressure to obtain the degree of consolidation.

[0046] Based on the above layout, a complete heating process of this solar-air energy complementary intelligent heating consolidation construction system is as follows: Figure 4 As shown.

[0047] The solar-air energy complementary intelligent heating consolidation construction system in this embodiment reduces energy consumption in the foundation treatment method of thermal consolidation drainage by using solar-air energy complementarity, and also reduces the construction period required for foundation consolidation. Based on the real-time feedback of soil temperature in each heating consolidation drainage zone by the temperature measuring device 6, hot water is promptly replenished to the heating consolidation drainage zone with lower temperature, thereby improving energy utilization.

[0048] The solar-air energy complementary intelligent heating and consolidation construction system proposed in this application can optimize the layout of drainage boards 4 according to the geological conditions of the thermal consolidation drainage zone, achieving better heating and consolidation drainage effect with less resource consumption and improving the foundation consolidation rate. By complementing solar and air energy, two clean energy sources, hot water circulation between drainage boards 4 is achieved, making the foundation treatment method of thermal consolidation drainage low-carbon and low-energy consumption. In response to the problem of uneven soil temperature distribution in the heating and consolidation drainage zone, a temperature measuring device 6 is used to feed back the soil temperature of the heating and consolidation drainage zone to the system in real time, and hot water is only supplemented to the heating and consolidation drainage zone with lower temperature, thereby improving energy utilization.

[0054] (4) When the solar radiation is less than the set value, the air source heating device is controlled to obtain heat energy from the air and the heat energy obtained from the air is used to heat the hot water drawn from the drainage plate into the insulated water tank.
