[0002] Existing soft soil foundation treatment devices are mainly used to improve and reinforce the problems of low bearing capacity, poor stability, and large deformation of soft soil foundations. Common treatment methods include preloading, replacement, and reinforcement methods. The preloading method accelerates the discharge of pore water in the soil by applying preloading, thereby improving the bearing capacity and stability of the foundation. The replacement method is to excavate the soft soil layer and replace it with sand, gravel and other materials to increase the bearing capacity of the foundation. Reinforcement methods include deep mixing, high-pressure jet grouting, soil nailing walls and other technologies, which enhance the strength and stability of the soil by adding solidifying materials to the soil or using special equipment.

[0003] The specification of Chinese invention patent CN114197443B discloses a soft soil foundation processing device, including a spiral drill bit and a connecting shaft. The spiral drill bit is welded to the lower end of the connecting shaft. The connecting shaft drives the toggle mechanism to rotate, so that the toggle lever drives the rotating pressure plate to squeeze the air bag, so that the gas inside the air bag enters the interior of the heat-conducting column and blows air to the ventilation holes to prevent the ventilation holes from being blocked by soil, accelerate the circulation of heat from the heat-conducting column, and enable the heat-conducting column to quickly heat the soil and improve the heating efficiency; in the process of squeezing the air bag, the protective shell is also driven to rotate intermittently on the upper side of the spiral drill bit, so that the heat-conducting column fully heats the soil, reduces the moisture in the soil, and solidifies the soil; when the toggle lever is separated from the rotating pressure plate, the spring drives the rotating pressure plate to return to the initial state, so that the air bag automatically sucks water vapor into the interior of the protective shell, and is quickly extracted by the vacuum device, thereby reducing the loss of the vacuum device and saving energy.

[0043] An auxiliary heat pipe 6 is threadedly connected to one end of the guide shaft 4 close to the outer shell tube 1. The auxiliary heat pipe 6 includes a main body 61. The upper and lower ends of the main body 61 are provided with flat grooves, and the flat grooves are provided with water permeable holes; a through hole matching the auxiliary heat pipe 6 is provided on the outer shell tube 1; a filter is installed in the water permeable hole, and a pressure sensor matching the filter is installed on the inner wall of the water permeable hole.

[0044] An electromagnetic valve is connected between the guide shaft 4 and the vacuum tube 2, a sealing shell 62 is slidably connected in the main body 61, an electromagnet 63 is fixedly connected to the end of the main body 61 away from the vacuum tube 2, a permanent magnet matching the main body 61 is installed on the sealing shell 62, a limited telescopic rod is connected between the main body 61 and the sealing shell 62, and when the sealing shell 62 reaches the maximum displacement, the sealing shell 62 closes the water permeable hole;

[0045] Optionally, a self-resetting stretching spring is provided in the limit telescopic rod, and when the electromagnet 63 is turned on, the sealing shell 62 moves outward to stretch the self-resetting stretching spring, and after the electromagnet 63 is turned off, the sealing shell 62 is reset by the self-resetting stretching spring;

[0046] One end of the main body 61 close to the guide shaft 4 is fixedly connected with a one-way jet pipe 64. A branch air pipe communicating with the air supply pipe 9 is penetrated in the partition plate 3. The input end of the one-way jet pipe 64 is connected to the branch air pipe through an elastic hose.

[0047] An electric motor 7 is embedded and installed on the inner wall of the outer shell 1, and a driving gear column 71 meshing with the inner gear ring 5 is fixedly connected to the power output end of the electric motor 7;

[0048] A plurality of evenly distributed jet belts 8 are fixedly connected to the outer wall of the outer shell tube 1. The jet belts 8 are located between two adjacent through holes. Each jet belt 8 is connected to a partition plate 3. A plurality of evenly distributed jet holes are provided at the side ends of the jet belts 8.

[0049] The jet belt 8 includes a tube strip 81, in which a first inner tube 82 and a second inner tube 83 are arranged in pairs, the end of the second inner tube 83 is closed, a three-way solenoid valve 84 is connected between the bottom ends of the first inner tube 82 and the second inner tube 83, the input end of the first inner tube 82 is connected to a partition plate 3, the output end of the three-way solenoid valve 84 is connected to another partition plate 3, the top end of the second inner tube 83 is closed, and the side ends of the first inner tube 82 and the second inner tube 83 are connected to a plurality of evenly distributed nozzles.

[0050] An air delivery pipe 9 matching with the multiple jet belts 8 is provided between the multiple partition plates 3 , and an air pump and a heater are installed at the input end of the air delivery pipe 9 .

[0051] When the present solution is working, the hot air flow is firstly charged into the multiple partition plates 3 through the air delivery pipe 9, and then the hot air flow is input into the jet belt 8, so that the hot air flow is ejected to both sides through the first inner tube 82 and the second inner tube 83 in the jet belt 8; the area outside the auxiliary heat pipe 6 is heated, and then the motor 7 is controlled to work, so that the active gear column 71 rotates, drives the inner gear ring 5 to rotate, and then drives the multiple driven gear columns 44 to rotate, and finally drives the second bevel gear 43 to drive the first bevel gear 42 to rotate, so that the threaded air pipe 41 rotates, and the main pipe body 61 moves outward;

[0052] Then, the main body 61 is exposed outside the outer shell tube 1. At this time, the electromagnetic opening and closing valve on the guide shaft 4 is opened, and vacuum is drawn through the vacuum tube 2, so that the moisture in the soil enters the main body 61 through the water-permeable holes, thereby draining the moisture in the soil to reinforce the soft soil;

[0053] Optionally, during the soil reinforcement process, the electromagnetic on-off valve is closed, and then the electromagnet 63 is opened, so that the electromagnet 63 repels the permanent magnet on the sealing shell 62, so that the sealing shell 62 moves inward until the sealing shell 62 closes the water permeable hole. At this time, air is supplied to the one-way air injection pipe 64 through the air supply pipe 9, so that the main body 61 is filled with hot air flow. At this time, the main body 61 is heated as a whole and heat-treats the surrounding soil to reinforce the soil;

[0054] After the heating is completed, the electromagnet 63 is closed to reset the sealing shell 62 (reset is achieved by air flow or the self-resetting tension spring in the limit telescopic rod). At this time, air is further supplied through the one-way jet pipe 64 to make the main body 61 spray air out of the water permeable hole to loosen the solidified and blocked soil at the water permeable hole so that the water vapor can be extracted when the vacuum tube 2 works later; after the one-way jet pipe 64 supplies air for a set time, it stops working and the electromagnetic opening and closing valve is restored to open.

[0055] When the present solution is working, the auxiliary heat pipe 6 used for water vapor extraction can be displaced outward to be further inserted into the soil, so that the auxiliary heat pipe 6 can further expand the soil heating area and adjust the water vapor extraction range, and the auxiliary heat pipe 6 can actively store air by closing the water permeable hole through the sealing shell 62 for heating, and after the auxiliary heat pipe 6 opens the water permeable hole, the water permeable hole can be cleaned by the airflow discharged from the auxiliary heat pipe 6 to prevent the water permeable hole from being blocked.

[0056] Second implementation method:

[0057] Fig. 9 - Fig.10 As shown, it also includes an auxiliary processing system, which includes a processor, and the processor is connected to a control module, a monitoring module, a data processing module and a data storage module;

[0058] A control module, used to control the operation of the air pump, the electromagnet 63, the electromagnetic stop valve and the plurality of motors 7;

[0059] A monitoring module is used to collect monitoring data, including soil moisture outside the outer shell 1, pressure sensor data, and temperature monitoring data of the jet belt 8 and the auxiliary heat pipe 6. The jet belt 8 and the auxiliary heat pipe 6 are equipped with temperature sensors, and the outer wall of the outer shell 1 is equipped with a humidity sensor;

[0060] A data processing module is used to process monitoring data and adjust the operation of the control module according to the monitoring data;

[0061] The data storage module stores monitoring data and work logs;

[0062] The control module is provided with a unidirectional jet mode and a bidirectional jet mode. In the unidirectional jet mode, the jet is ejected outward through the first inner tube 82, and in the bidirectional jet mode, the jet is ejected outward through the first inner tube 82 and the second inner tube 83;

[0063] In the one-way jet mode, the three-way solenoid valve 84 closes the input end of the second inner tube 83. At this time, the air supply pipe 9 supplies air to the first inner tube 82 through the partition plate 3, and the air flow is ejected outward through the nozzle on the first inner tube 82.

[0064] In the two-way jet mode, the three-way solenoid valve 84 is adjusted to make the input end of the second inner tube 83 communicate with the output end of the first inner tube 82. At this time, the gas supply pipe 9 supplies gas to the first inner tube 82, and the air flow passes through the first inner tube 82 to the second inner tube 83. The air flow is sprayed to both sides through the nozzles on the first inner tube 82 and the second inner tube 83;

[0065] Optionally, in the two-way jet mode, the three-way solenoid valve 84 is adjusted so that its bottom input port is connected to both the first inner tube 82 and the second inner tube 83. At this time, the partition plate 3 located at the lower side of the three-way solenoid valve 84 supplies air, so that the airflow is simultaneously supplied to the first inner tube 82 and the second inner tube 83 and sprayed out through the nozzle.

[0066] This solution is convenient for selecting the most suitable jetting method, heating range and water vapor suction position according to different construction stages and soil conditions, thereby improving treatment efficiency and quality, and the water vapor suction work is not easily affected by blockage during operation.

[0067] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
