Technical Field

[0001] This invention relates to the field of water conservancy engineering and dike engineering technology, specifically to a high-pressure steam aeration device for drilling holes in soil layers. Background Technology

[0002] Most of the soil used for building dikes in water conservancy projects comes from the riverbanks on the water-facing side of the dikes. The moisture content of the soil increases significantly every year during the flood season, making the dike construction progress uncontrollable. If more drying and turning areas are added, large-scale land acquisition is required, and the drying and turning costs will also increase significantly, indirectly increasing the project investment.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, so as to provide a better understanding of the concept of the present invention, the technical problem solved, the technical features constituting the technical solution, and the technical effects brought about.

[0025] like Figure 1 and Figure 2 As shown, a high-pressure steam aeration device for soil drilling includes a mobile trolley 1, a lifting device, a steam generator 6, a drilling pipe 8, a first rotating device, and a lifting plate 10. When using this device for aeration, the steam generator 6 is activated. An electric heating plate is installed at the bottom of the steam generator 6, and a spiral heat-conducting pipe is installed at the top of the heating plate. Simultaneously, a water tank is installed on the mobile trolley 1. Water from the water tank enters the steam generator 6 through a connecting pipe. The electric heating plate heats the spiral heat-conducting pipe, heating the water in the steam generator 6 to form high-temperature steam. Activating the lifting device moves the lifting plate 10 downwards, which in turn moves the drilling pipe 8 downwards. The first rotating device rotates the drilling pipe 8, enabling the drilling pipe 8 to move downwards and drill. The telescopic pipe 72 can adapt to the downward movement of the drilling pipe 8, drilling to a suitable depth. After reaching a certain depth, high-pressure steam is delivered into the borehole pipe 8 and discharged into the soil layer through the first vent 801. The high-pressure steam entering the soil layer quickly vaporizes the liquid water in the underground soil layer into water vapor. Multiple first vent 801s can be set to improve the inflation efficiency and simultaneously inflate soil layers at different depths. After the inflation operation is completed, the lifting device is activated to drive the lifting plate 10 upward, and the borehole pipe 8 moves upward to detach from the soil layer. The moving trolley 1 moves by the universal wheels 101 at the bottom to another area for operation. In order to further increase the steam capacity, a steam storage tank 7 can also be set. The steam heated by the steam generator 6 is transported to the steam storage tank 7 for storage through the compression pump 71 and the gas delivery pipe. The rotary joint 73 can realize the pipeline connection without causing the connecting telescopic pipe 72 to twist.

[0026] like Figure 1 and Figure 2 As shown, an exhaust pipe 11 and a second rotating device are also provided. When exhausting, the second rotating device is activated, and the second motor 1201 rotates, driving the first bevel gear 1202 to rotate. Since the first bevel gear 1202 and the second bevel gear 1203 mesh, the second bevel gear 1203 drives the exhaust pipe 11 to rotate. When the second exhaust hole 1101 on the exhaust pipe 11 and the first exhaust hole 801 on the borehole pipe 8 are aligned, the high-pressure steam is discharged from the telescopic pipe 72 through the exhaust pipe 11 and the borehole pipe 8 into the soil layer. The discharge of high-pressure steam can be better controlled through the first exhaust hole 801 and the second exhaust hole 1101.

[0027] like Figure 1As shown, starting the third motor 508 rotates the lead screw 501. Since the rack 502 is screwed to the lead screw 501, the rack 502 moves left and right, causing the drive column 509 on the tooth surface of the first gear 506 to rotate. Because the drive column 509 is engaged in the elongated through hole of the loop block 507, when the drive column 509 follows the arc movement of the first gear 506, it causes the loop block 507 to move up and down, completing the lifting operation. The setting of the drive column 509 allows for more precise control of the lifting height. When setting the third motor 508, in order to better fix the third motor 508, it is installed on the upper end face of the moving trolley 1 and connected to the lead screw 501 through belt drive. When setting the lifting device, an electric push rod can also be used for vertical setting.

[0028] like Figure 1 As shown, a lifting device can be installed at both the left and right ends, working together to push the lifting plate 10 up and down, thus improving the accuracy of the movement.

[0029] like Figure 1 As shown, starting the first motor 901 causes the second gear 902 to rotate. Since the second gear 902 meshes with the third gear 903, the third gear 903 rotates accordingly, driving the drill pipe 8 to rotate and completing the drilling operation. Depending on the installation position and output shaft of the first motor 901, a bevel gear can also be used to drive the drill pipe 8 to rotate.

[0030] like Figure 1 As shown, when inflating the soil, a fixing device is also provided to stabilize the mobile trolley 1. After the mobile trolley 1 moves to the work area, the operator rotates the reciprocating screw 1306. The rotation of the reciprocating screw 1306 drives the threaded plate 1302 to move downward. The threaded plate 1302 drives the first limit rod 1303 and the second limit rod 1304 to move downward, and the positioning tooth plate 1305 moves downward. The serrations at the bottom insert into the soil to complete the fixation. In order to make the device more stable, a fixing device is set at both ends of the mobile trolley 1 for fixation. After the operation is completed, the positioning tooth plate 1305 can be removed from the soil by moving in the opposite direction. In order to make it easier for the operator to operate the fixing device, a turntable can also be set at the top of the reciprocating screw 1306 to drive the reciprocating screw 1306 to rotate.

[0031] like Figure 1 As shown, in order to better control the input of high-pressure steam, a solenoid valve 14 is installed on the gas supply pipe between the steam generator 6 and the telescopic pipe 72, and is controlled by the control panel 2 on the side wall of the moving trolley 1. When the steam storage tank 7 is vertical, the solenoid valve 14 can be installed on the gas supply pipe between the steam storage tank 7 and the telescopic pipe 72, and the storage battery 3 can power the device.

[0032] like Figure 1As shown, in order to achieve better drilling results, a threaded drill bit 4 is installed at the bottom of the drill pipe 8. The threaded drill bit 4 is used to drill holes in the soil layer, which improves the work efficiency.
