Before use, a lower compression spring 308 with proper length is selected (after the soil planing wheel 306 is in contact with the ground, the lower compression spring 308 is still in a compressed state), then the soil planing wheel 306 is sleeved on the spline shaft 309, at the moment, the soil planing wheel 306 can be in contact with the ground under the action of gravity and the elastic force of the lower compression spring 308, then the soil planing motor 302 is started, an output shaft of the soil planing motor 302 drives the transmission shaft 305 to rotate through the transmission belt 304, the transmission shaft 305 drives the soil planing wheel 306 to rotate through the spline shaft 309, and the soil planing wheel 306 is used for trimming and leveling the ground surface.

The swing handle 208 is swung by hand, the swing handle 208 drives the extrusion swing arm 209, the extrusion swing arm 209 swing can extrude the slide steel sheet 210, the slide steel sheet 210 extrudes the elastic film 211 (the elastic film 211 compresses, in order to dodge the extrusion swing arm 209), let the extrusion swing arm 209 swing towards the direction of keeping away from the removal supporting seat 213 this moment, make its extrusion swing arm 209 separate with the slide steel sheet 210 (make its extrusion force of two disappear), then crossbeam 207 no longer atress, the dull and stereotyped 206 of extrusion no longer atress, let the rubber pad in the extrusion groove 2061 separate with the guide slide bar 205, the guide slide bar 205 no longer receives frictional force this moment, then can free whereabouts, synchronous counter weight frame 201 also can free whereabouts. On the contrary, when the swing handle 208 is swung to enable the pressing swing arm 209 to swing towards the direction of the moving support 213, the pressing swing arm 209 will press the sliding steel plate 210 to compress the elastic film 211, then the pressing swing arm 209 swings to a position contacting with the moving support 213 to clamp the pressing swing arm 209 between the beam 207 and the sliding steel plate 210 (since the movement of the beam 207 is limited by the guiding sliding rod 205, the movement of the pressing swing arm 209 is limited by the sliding steel plate 210, and at this time, the swinging angle of the pressing swing arm 209 is not parallel to the moving support 213 but is an included angle set at a negative angle with the moving support 213, so the force applied by the pressing swing arm 209 will be directed to the moving support 213 to clamp the pressing swing arm 209).
The falling of the counterweight frame 201 causes the hanging frame 102 to fall through the damping slide bar 203, the falling of the hanging frame 102 causes the measuring beam arm 101 to fall, the first acoustic wave receiving sensor 107, the second acoustic wave receiving sensor 108, the first ultrasonic probe 116 and the second ultrasonic probe 117 on the measuring beam arm 101 are in contact with the ground, then slide with the ground while following movement, and after a certain distance of movement, the movement is stopped, and then detection is performed. Wherein the first ultrasonic probe 116 and the second ultrasonic probe 117 emit ultrasonic waves, and when the corresponding sound waves strike the pipeline, the ultrasonic waves return to the first ultrasonic probe 116 and the second ultrasonic probe 117, and the distance between the first ultrasonic probe 116 and the second ultrasonic probe 117 and the pipeline is determined by determining the round trip time of the sound waves, so that the distance between the first ultrasonic probe 116 and the second ultrasonic probe 117 and the pipeline is ensured to be the same, the first sound wave receiving sensor 107 and the second sound wave receiving sensor 108 are ensured to be positioned right above the pipeline, for improving the measurement accuracy, and the like, the difference between the two can be used for judging the specific position of the pipeline under the ground, and the function of guiding the device to advance (controlling the moving direction to move along the direction of the pipeline) can be realized. And the first sound wave receiving sensor 107 and the second sound wave receiving sensor 108 are arranged along the moving direction, so that when the sound wave (not the ultrasonic wave on the first ultrasonic probe 116 and the second ultrasonic probe 117) received by the first sound wave receiving sensor 107 (the direction of the first sound wave receiving sensor 107 is exemplified herein as the advancing direction) is abnormal, it is indicated that there is breakage of the pipe in front, the intensity of the sound wave received by the first sound wave receiving sensor 107 becomes larger and larger as the movement is continued, then the sound wave is also received by the second sound wave receiving sensor 108, but the intensity of the sound wave received by the second sound wave receiving sensor 108 is smaller than that of the first sound wave receiving sensor 107, when the intensity of the sound wave received by the first sound wave receiving sensor 107 is weakened, the position below the position is a position where the pipeline is damaged, but the intensity of the sound wave received by the second sound wave receiving sensor 108 is gradually increased, and when the intensity of the sound wave received by the first sound wave receiving sensor 107 and the intensity of the sound wave received by the second sound wave receiving sensor 108 are the same, the position right below the device is a position where the pipeline is damaged, and punctuation is performed on a map at the moment for subsequent maintenance personnel to carry out rush repair. In summary, the example between the first sound wave receiving sensor 107 and the second sound wave receiving sensor 108 determines the accuracy of measurement, so that the distance between the first sound wave receiving sensor 107 and the second sound wave receiving sensor 108 is selected appropriately according to the depth of the pipe buried under the ground (the distance between the first sound wave receiving sensor 107 and the second sound wave receiving sensor 108 may also be made non-adjustable, and selected according to the actual situation). When the distance between the first sound wave receiving sensor 107 and the second sound wave receiving sensor 108 needs to be adjusted, the adjusting motor 115 is started, the output shaft of the adjusting motor 115 drives the rotating disk 113 to rotate, the rotating disk 113 drives all the limiting deflector rods 110 to rotate, the limiting deflector rods 110 drive the triangular friction limiting blocks 111 to move downwards towards the inclined planes of the triangular grooves 1061, so that the triangular friction limiting blocks 111 are separated from the inner walls of the friction limiting cover 109, and the other symmetrical triangular friction limiting blocks 111 also move downwards towards the inclined planes of the triangular grooves 1061 under the action of friction force with the friction limiting cover 109, the check disc 106 can rotate when the check disc 106 is separated from the inner wall of the friction limiting cover 109, the check disc 106 rotates to drive the adjusting gear 104 to rotate and then drive the first rack 103 and the second rack 105 to move so as to drive the corresponding first sound wave receiving sensor 107 and second sound wave receiving sensor 108 to move and adjust the distance between the first sound wave receiving sensor 107 and the second sound wave receiving sensor 108, the first sound wave receiving sensor 107 and the second sound wave receiving sensor 108 can receive the friction force of the ground, so that the force is transmitted to the adjusting gear 104 and then transmitted to the check disc 106, in order to prevent the check disc 106 from rotating, that is, in order to prevent the distance between the first sound wave receiving sensor 107 and the second sound wave receiving sensor 108 from changing in the process of friction with the ground, when the check disc 106 rotates in any direction, the friction force between one of the triangular friction limiting blocks 111 and the friction limiting cover 109 drives the triangular friction limiting block 111 to move upwards towards the inclined surface of the triangular groove 1061, so that the triangular friction limiting block is clamped between the triangular groove 1061 and the inner wall of the friction limiting cover 109, and the rotation of the check disc 106 is limited.
