[0032] The technical effect of the above solution is that it enables the formation of an intermediate integrated component and realizes vertical movement on the support platform.

[0033] The present invention is designed such that the bearing platform and the hinged frame are distributed with the first track, the second track, the mobile frame and the longitudinal moving unit in a way that pushes the seat, and the bearing platform, the hinged frame, the first track, the second track, the mobile frame and the longitudinal moving unit are distributed with the vertical moving unit and the thrust telescopic cylinder in a way that extends and supports.

[0035] This invention designs a comprehensive testing method for subgrade, the steps of which are: a rail locomotive connects and supports the comprehensive subgrade testing instrument and subgrade construction equipment; a bearing platform connects and supports the subgrade for comprehensive testing; and a movable frame connects and supports the bearing platform by changing its distribution state, thereby enabling the subgrade for comprehensive testing to be in a stationary state during the test and in a self-flowing state after the test.

[0036] The technical effect of the above technical solution is that it highlights the technical characteristics of the soil foundation in the comprehensive test being in a stagnant state during the test and in a self-flowing state after the test, and introduces its application in the technical field of comprehensive test methods for soil foundations.

[0037] The present invention is designed with the following steps: When telescopic cylinder I and telescopic cylinder II perform telescopic movements, telescopic cylinder I swings between the second lug I and the first lug II, and telescopic cylinder II swings between the third lug I and the second lug II, causing the first lug I to swing at the upper end of the insert beam, thus putting the frame in a flipped state and adjusting the tilt angle of the bearing platform. When telescopic cylinder III performs telescopic movements, telescopic cylinder III moves between the upper end face of seat I and the lower end face of lug II, causing the lower end of the insert beam to move up and down within the cylinder of seat I, putting the frame in a stepped height state and adjusting the height of the bearing platform. When the moving frame is in operation... In operation, the wheels are energized and rotate on the pin located in the ear seat III, causing them to move along the first and second tracks, thus enabling the moving trolley to move laterally along these tracks. When the moving trolley is not in operation, the wheels are de-energized and stop rotating on the pin located in the ear seat III. When the longitudinal moving unit is in operation, motor I and motor II are energized, driving the ends of lead screw I and lead screw II to rotate in the rotating holes of the supporting beam I and supporting beam II, respectively. Through the threaded movement of the receiving hole II with lead screw I and lead screw II, the receiving groove II moves between the crossbeams of the entire beam I and the entire beam II. The movement allows the longitudinal moving unit to move longitudinally on the moving frame, adjusting the longitudinal position of the vertical moving unit and the thrust telescopic cylinder. When the longitudinal moving unit is not in operation, motor I and motor II are de-energized, causing the ends of lead screw I and lead screw II to stop rotating in the rotating holes of support beam I and support beam II, respectively. When the vertical moving unit is in operation, when telescopic cylinder IV is in the extended state, it causes the front and rear vertical bodies of the moving frame to move upward in the receiving tank I, placing the moving frame in a high position. When telescopic cylinder IV is in the retracted state, it causes the front and rear vertical bodies of the moving frame to move downward in the receiving tank I, placing the moving frame in a low position. When Part III is energized, it drives the end of the lead screw to rotate in the rotating hole of the moving frame. Through the threaded hole of the nut seat II and the threaded movement of the lead screw III, the receiving groove III moves on the front and rear vertical bodies of the moving frame, adjusting the vertical position of the nut seat II. When the vertical moving unit is not in operation, the motor part III is de-energized, causing the end of the lead screw III to stop rotating in the rotating hole of the moving frame. When a comprehensive soil test is required, the movable frame is placed between the first and second tracks, the ground nail is placed in the through hole of the seat I, the tip of the ground nail is driven into the comprehensive test foundation, the end of the curtain belt is placed on the end of the frame, and then the pressure plate is placed on the end of the curtain belt.Insert the intermediate connecting bolt into the through hole of the pressure plate, allowing the inner end of the bolt to rotate within the threaded hole at the end of the frame. This causes the flange of the bolt to act on the pressure plate, thereby installing the curtain section between two adjacent movable frames. Using the intermediate connecting bolt, install the bearing platform onto the frame. By adjusting the frame's tilting state and step height, the inclination angle and height of the bearing platform correspond to the distribution of the subgrade support structure. This allows the bearing platform and movable frame to be installed between the first and second tracks, placing the moving frame in a high position. Connect the intermediate connecting frame on the subgrade construction equipment to the telescopic end of the thrust telescopic cylinder. The moving trolley moves laterally on the first and second tracks, and the longitudinal moving unit moves longitudinally on the moving trolley, causing the subgrade construction equipment to move on the bearing platform. Subgrade construction is then performed on the bearing platform, resulting in the subgrade structure located on the bearing platform. After the soil foundation construction on the bearing platform is completed, the intermediate connecting frame on the soil foundation construction equipment is separated from the telescopic end of the thrust telescopic cylinder. The soil foundation comprehensive testing instrument is connected to the installation opening, and the moving frame is in a low position. The moving trolley moves laterally on the first and second tracks, and the longitudinal moving unit moves longitudinally on the moving trolley, positioning the soil foundation comprehensive testing instrument at the soil foundation testing point. By adjusting the vertical position of the nut seat II, the height of the soil foundation comprehensive testing instrument is adjusted, and parameters of the soil foundation on the bearing platform are tested, thus achieving a comprehensive soil foundation test. After the comprehensive soil foundation test is completed, the soil foundation comprehensive testing instrument is separated from the installation opening, and the moving frame is in a high position. Then, by adjusting the flipping state of the frame and its step height, the tilt angle and height of the bearing platform meet the requirements for the soil foundation to slide down, allowing the soil foundation to automatically move off the bearing platform.

[0038] The technical effect of the above solution is that it enables the operation of the soil foundation used for comprehensive testing through the linkage and flipping of the transport platform during construction and removal.

[0039] In this technical solution, the supporting platform and the movable frame are the basic components and essential technical features of the invention. The first track, the second track, the moving frame, the longitudinal moving unit, the vertical moving unit, and the thrust telescopic cylinder are functional components, features that achieve other technical effects of the invention. The design of the frame section, the curtain belt section, the insert beam section, the telescopic cylinder section I, the telescopic cylinder section II, the telescopic cylinder section III, the seat section I, the ground nail section, the ear seat section I, the ear seat section II, the seat section II, the wheel section, the ear seat section III, the through beam section I, the through beam section II, the supporting crossbeam section I, the supporting crossbeam section II, the lead screw section I, the motor section I, the lead screw section II, the motor section II, the nut seat section I, the ear seat section III, the receiving hole section I, the receiving groove section I, the receiving groove section II, the receiving hole section II, the moving frame section, the lead screw section III, the motor section III, the nut seat section II, the telescopic cylinder section IV, the receiving groove section III, and the installation opening are technical features that comply with the Patent Law and its implementing regulations.

[0040] In this technical solution, the stagnant state of the soil foundation during the comprehensive test and the self-flowing state after the test are achieved by the movable frame and the bearing platform.

[0041] The key technical features of this technical solution are the track locomotive, the movable frame, and the bearing platform that enable the soil foundation to be in a stagnant state during the test and in a self-flowing state after the test.

[0073] The present invention will be further described below with reference to embodiments. These embodiments are intended to illustrate the present invention and not to further limit the present invention.

[0074] A comprehensive testing method for soil subgrade includes the following steps: When telescopic cylinder I 23 and telescopic cylinder II 24 extend and retract, telescopic cylinder I 23 swings between its second lug I 28 and its first lug II 29, and telescopic cylinder II 24 swings between its third lug I 28 and its second lug II 29, causing the first lug I 28 to swing at the upper end of the insert beam 22, thus putting the frame 21 in a flipped state and adjusting the tilt angle of the bearing platform 1. When the telescopic cylinder III 25 extends or retracts, it moves between the upper end face of the seat I 26 and the lower end face of the ear seat II 29, causing the lower end of the insert beam 22 to move up and down within the cylinder of the seat I 26. This positions the frame 21 in a stepped height position, adjusting the height of the bearing platform 1. When the mobile carriage 5 is in operation, the wheel 52 is energized and rotates on the pin located on the ear seat Ⅲ 53, causing the wheel 52 to move along the first track 3 and the second track 4, thus causing the mobile carriage 5 to move laterally along the first track 3 and the second track 4. When the mobile carriage 5 is not in operation, the wheel 52 is de-energized and stops rotating on the pin located on the ear seat Ⅲ 53. When the longitudinal moving unit 6 is in operation, motor section I 64 and motor section II 66 are energized, driving the ends of lead screw section I 63 and lead screw section II 65 to rotate in the rotating holes of supporting beam section I 61 and supporting beam section II 62, respectively. Through the threaded movement of receiving hole II 602 with lead screw section I 63 and lead screw section II 65, receiving groove II 601 is positioned in the middle of the cross body of the through beam section I 54 and through beam section II 5. The horizontal movement of unit 5 causes the longitudinal moving unit 6 to move longitudinally on the moving frame 5, adjusting the longitudinal position of the vertical moving unit 7 and the thrust telescopic cylinder 8. When the longitudinal moving unit 6 is in a non-working state, motor I 64 and motor II 66 are de-energized, causing the ends of lead screw I 63 and lead screw II 65 to stop rotating in the rotating holes of support beam I 61 and support beam II 62, respectively. When the vertical moving unit 7 is in operation, when the telescopic cylinder part IV 75 is in the extended state, it drives the front and rear vertical bodies of the moving frame part 71 to move upward in the receiving tank I 60, so that the moving frame part 71 is in a high position. When the telescopic cylinder part IV 75 is in the retracted state, it drives the front and rear vertical bodies of the moving frame part 71 to move downward in the receiving tank I 60, so that the moving frame part 71 is in a low position. The motor part III 73 is energized, driving the end of the lead screw part III 72 to rotate in the rotating hole of the moving frame part 71. Through the threaded hole of the nut seat part II 74 and the threaded movement of the lead screw part III 72, the receiving tank III 76 moves on the front and rear vertical bodies of the moving frame part 71, adjusting the vertical position of the nut seat part II 74. When the vertical moving unit 7 is not in operation, the motor part III 73 is de-energized, driving the end of the lead screw part III 72 to stop rotating in the rotating hole of the moving frame part 71. When a comprehensive test of the subgrade is required, the movable frame 2 is placed between the first track 3 and the second track 4. The ground nail part 27 is placed into the through hole of the seat part I 26, and the tip of the ground nail part 27 is driven into the comprehensive test subgrade. The end of the curtain belt part 20 is placed on the end of the frame part 21, and then the pressure plate is placed on the end of the curtain belt part 20. The intermediate connecting bolt is placed into the through hole of the pressure plate, so that the inner end of the intermediate connecting bolt rotates in the threaded hole at the end of the frame part 21, so that the flange of the intermediate connecting bolt acts on the pressure plate, thereby installing the curtain belt part 20 between two adjacent movable frames 2. Through the intermediate connecting bolt, the bearing platform 1 is installed on the frame part 21. By adjusting the flip state of the frame part 21 and the state of the step height, the tilt angle and height of the bearing platform 1 correspond to the distribution state of the subgrade support base, thereby installing the bearing platform 1 and the movable frame 2 between the first track 3 and the second track 4. The mobile frame 71 is positioned at a high position. The intermediate connecting frame on the soil foundation construction equipment is connected to the telescopic end of the thrust telescopic cylinder 8. The mobile frame 5 moves laterally on the first track 3 and the second track 4, and the longitudinal moving unit 6 moves longitudinally on the mobile frame 5, causing the soil foundation construction equipment to move on the bearing platform 1. Soil foundation construction is carried out on the bearing platform 1, resulting in a soil foundation located on the bearing platform 1. After the soil foundation construction on the bearing platform 1 is completed, the intermediate connecting frame on the soil foundation construction equipment is connected to the thrust telescopic cylinder 8. The telescopic cylinder 8 separates its telescopic ends, connecting the comprehensive soil testing instrument to the installation opening 77. This lowers the movable frame 71. The movable carriage 5 moves laterally on the first track 3 and the second track 4, while the longitudinal moving unit 6 moves longitudinally on the movable carriage 5, positioning the comprehensive soil testing instrument at the soil testing point. The height of the instrument is adjusted by regulating the vertical position of the nut seat Ⅱ 74, allowing for parameter testing of the soil located on the bearing platform 1, thus enabling a comprehensive soil test. After the comprehensive test of the subgrade is completed, the subgrade comprehensive testing instrument is separated from the installation opening 77, so that the moving frame part 71 is in a high position. Then, by adjusting the flipping state of the frame part 21 and the state of the step height value, the tilt angle and height of the bearing platform 1 are made to meet the requirements for the subgrade to slide down and move, so that the subgrade is automatically moved off the bearing platform 1.

The lateral movement of vehicle 5 on the bearing platform 1 increases the load-bearing capacity, resulting in the fourth unexpected technical effect: longitudinal movement of the longitudinal moving unit 6 on the bearing platform 1 increases the operating range of the soil foundation comprehensive testing instrument and the soil foundation construction equipment, resulting in the fifth unexpected technical effect: vertical position adjustment of the soil foundation comprehensive testing instrument is achieved through the vertical moving unit 7, improving the height and position accuracy of the instrument and its measurement accuracy, resulting in the sixth unexpected technical effect: vertical position adjustment of the soil foundation construction equipment is achieved through the thrust telescopic cylinder 8, improving the lifting strength of the equipment, resulting in the seventh unexpected technical effect: it eliminates the need for the use of integrated comprehensive testing chambers. This increases the inspection The difficulty of the completed foundation demolition was assessed, eliminating interfering factors that could hinder the demolition process and improving efficiency.
