An outer shaft sleeve 306 is fixedly arranged in the middle of the transverse moving platform 304, and an inner shaft sleeve 307 is arranged inside the outer shaft sleeve 306. A ramming hammer rod 308 is slidably connected inside the inner shaft sleeve 307, and a ramming hammer head 309 is arranged at the lower end of the ramming hammer rod 308. A positioning sleeve 31 is sleeved on the ramming hammer rod 308. 0, the positioning sleeve 310 is located below the inner shaft sleeve 307, and the position of the positioning sleeve 310 on the tamping hammer rod 308 is adjustable. The soil spreading device 2 and the compaction auxiliary device 3 can be movably arranged on the track 4. The soil spreading frame 201 and the compaction frame 301 are both movably connected with the track 4. The track 4 adopts a convex track. The soil spreading frame 201 and the compaction frame 301 are both provided with a slideway matching the convex track. The convex track and the slideway cooperate to realize sliding connection. The compaction mold 1 is arranged at a position between the soil spreading frame 201 and the compaction frame 301.

[0021] Working principle: when in use, the soil-laying device 2 is pushed to move it above the compaction mold 1, and the soil-laying hopper 202 is controlled to descend to a set height through the lifting drive device 205. The lifting drive device 205 adopts a third screw rod 206 set on the soil-laying machine frame 201. The upper and lower ends of the third screw rod 206 are connected to the soil-laying machine frame 201 through a bearing seat. A limit plate 207 is fixedly set on the top of the third screw rod 206. A thrust bearing 208 is set on the top of the third screw rod 206 between the bottom of the limit plate 207 and the bearing seat. The thrust bearing 208 cooperates with the bearing seat to provide axial support force for the third screw rod 206. A third screw sleeve 209 is fixedly set on the soil-laying hopper 202. The third screw sleeve 209 is sleeved on the third screw rod 206 and is screwed therewith. The worm gear 210 and the worm 211 are connected to each other through a worm wheel 210 and a worm screw 211. The worm 211 is connected to the soil paving frame 201 through a bearing seat. The worm 211 is connected to a driving motor or a hand crank. The worm gear 210 and the third screw rod 206 are coaxially fixed. The worm gear 210 and the worm screw 211 are connected in transmission. In order to better support the third screw rod 206, two screw rods 206 can be provided, which are symmetrically arranged on both sides of the soil paving frame 201 and driven by the same worm screw 211. When the worm screw 211 is driven to rotate, the third screw rod 206 rotates accordingly, thereby driving the soil paving hopper 202 to rise and fall. Since the worm gear 210 and the worm screw 211 have a reverse transmission locking function, that is, the worm gear 210 cannot drive the worm screw 211 to rotate, and the worm screw 211 can be driven to rotate. The wheel 210 can amplify the torque, which saves labor during manual operation. The lifting connection structure includes at least four slide grooves 212 arranged in the vertical direction on the soil paving frame 201, and sliders 213 are arranged around the soil paving hopper 202. The sliders 213 are slidably connected in the slide grooves 212. The lifting drive device 205 is used to make the soil outlet 203 at the bottom of the soil paving hopper 202 located at one end of the square cavity. The gate assembly 204 is opened to allow the soil to fall into the compaction mold 1. The soil paving frame 201 is slowly moved to allow the soil paving hopper 202 to move along the internal cavity of the compaction mold 1 to the other end of the square cavity to complete the soil paving. After the soil is paved, the soil paving hopper 202 is lifted by the lifting drive device 205, and then the soil paving device 2 is removed, and then the compaction auxiliary device 3 is moved to the compaction mold 1. At the top, the longitudinal moving platform 302 and the transverse moving platform 304 can be operated to adjust the position of the ramming hammer. After determining the position and height of the ramming hammer, lift the ramming hammer and let it fall freely. Repeat the operation until all the ramming operations are completed. After the ramming is completed, measure the thickness and density of the compacted soil layer inside the compaction mold 1, and analyze whether the actual earth site wall repair operation can achieve higher work efficiency while ensuring the quality of the rammed earth according to the soil laying thickness, ramming hammer weight and ramming times corresponding to this process. If the requirement of higher work efficiency while ensuring the quality of the rammed earth cannot be achieved, change the parameters such as soil laying thickness, ramming hammer weight and ramming times, and continue the measurement work.

[0022] The lower part of the soil paving hopper 202 gradually shrinks, and the gate assembly 204 can adopt a sliding gate plate 215 structure. A gate plate slide 214 is set at the lower end of the soil paving hopper 202. The gate plate slide 214 runs through the lower part of the soil paving hopper 202. A gate plate 215 is slidably set inside the gate plate slide 214. The gate plate 215 can prevent the discharge of soil. After the gate plate 215 is pulled out, the soil can be discharged. Rope holes 216 are provided at the front and back of the gate plate 215. The rope holes 216 can be fixed and retracted and can be used to manually control the opening and closing of the gate plate 215. Since the soil outlet 203 is located in the square cavity 101, the gate plate 215 needs to be movable in both the front and rear directions.

[0023] The first sliding structure includes two slide rails 311 arranged on the compaction frame 301, and the longitudinal moving platform 302 is provided with slide holes 312 matching the slide rails 311. The slide rails 311 pass through the slide holes 312 at corresponding positions, so as to realize the sliding connection between the longitudinal moving platform 302 and the compaction frame 301. The longitudinal moving platform 302 can move along the direction of the track 4, and is designed to adjust the position of the tamping hammer head.

[0024] The first locking assembly 303 includes a longitudinal positioning beam 313 arranged on the compaction frame 301, and a plurality of first positioning holes 314 are evenly distributed on the longitudinal positioning beam 313. A first pressure plate 315 is arranged on the longitudinal movable platform 302. The middle part of the first pressure plate 315 is hinged to the longitudinal movable platform 302 through a first pin shaft. One end of the first pressure plate 315 is located above the longitudinal positioning beam 313. A first pointed pin 316 is arranged at the bottom of the end of the first pressure plate 315 located above the longitudinal positioning beam 313. The first pointed pin 316 is inserted in the first positioning hole 314. The diameter of the first positioning hole 314 is between the maximum diameter and the minimum diameter of the pointed end of the first pointed pin 316. A first compression spring 317 is connected between the other end of the first pressure plate 315 and the longitudinal movable platform 302.

[0025] The hole spacing of the first positioning holes 314 is the distance that the ramming hammer 309 moves longitudinally each time. The hole spacing is related to and equal to the diameter of the ramming hammer 309. In actual use, longitudinal positioning beams 313 with various hole spacings can be set to adapt to ramming hammers 309 with various diameters. When the ramming hammer 309 is moved longitudinally, the first pressing plate 315 is lifted to make the first pointed pin 316 withdraw from the first positioning hole 314, and then the longitudinal moving platform 302 is moved to make the first pointed pin 316 snap into the next first positioning hole 314, so as to realize the positioning of the longitudinal moving platform 302, and the first pressing plate 315 is lifted to make the first pointed pin 316 withdraw from the first positioning hole 314. When the pressure plate 315 and the first pointed pin 316 withdraw from the first positioning hole 314, the other end of the first pressure plate 315 moves downward to compress the first compression spring 317. After the first pressure plate 315 is released, under the action of the first compression spring 317, the first pointed pin 316 is inserted into the next first positioning hole 314. The first compression spring 317 is welded and fixed to the first pressure plate 315 and the longitudinal moving platform 302 at both ends, or the first compression spring 317 is only welded to the longitudinal moving platform 302. A spring bowl is set at the bottom of the first pressure plate 315, and the upper end of the first compression spring 317 is located inside the spring bowl.

[0026] The second sliding structure includes a rectangular sliding hole 320 in the middle of the transverse moving platform 304, and the longitudinal moving platform 302 passes through the rectangular sliding hole 320 and is slidably connected thereto. In this way, the transverse moving platform 304 is slidably connected to the longitudinal moving platform 302, and the transverse moving platform 304 can move along the length direction of the longitudinal moving platform 302. In this way, the transverse moving platform 304 cooperates with the longitudinal moving platform 302 to adjust the position in the horizontal plane. Since the ramming hammer rod 308 is provided with a positioning sleeve 310, the positioning sleeve 310 is located below the inner shaft sleeve 307, and the position of the positioning sleeve 310 on the ramming hammer rod 308 is adjustable, and the highest height of the ramming hammer head 309 is adjustable.

[0027] The second locking assembly 305 includes a transverse positioning beam 321 arranged on the compaction frame 301, and a plurality of second positioning holes 322 are evenly distributed on the transverse positioning beam 321. A second pressure plate 323 is arranged on the transverse moving platform 304. The middle part of the second pressure plate 323 is hinged to the transverse moving platform 304 through a second pin shaft. One end of the second pressure plate 323 is located above the transverse positioning beam 321. A second pointed pin 324 is arranged at the bottom of the end of the second pressure plate 323 located above the transverse positioning beam 321. The second pointed pin 324 is inserted into one of the second positioning holes 322. The diameter of the second positioning hole 322 is between the maximum diameter and the minimum diameter of the pointed end of the second pointed pin 324. A second compression spring 325 is connected between the other end of the second pressure plate 323 and the transverse moving platform 304.

[0028] The hole spacing of the second positioning holes 322 is the distance that the ramming hammer 309 moves horizontally each time. The hole spacing is related to and equal to the diameter of the ramming hammer 309. In actual use, the horizontal positioning beams 321 with various hole spacings can be set to adapt to ramming hammers 309 with various diameters. When the ramming hammer 309 is moved horizontally, the first pressing plate is lifted to make the second pointed pin 324 withdraw from the second positioning hole 322, and then the horizontal moving platform 304 is moved to make the second pointed pin 324 snap into the next second positioning hole 322, so as to realize the horizontal moving platform 304 moving once for positioning, and the next movement is also Similarly, lift the second pressure plate 323, and the other end of the second pressure plate 323 moves downward to compress the second compression spring 325. After the transverse moving platform 304 is in place and the second pressure plate 323 is released, under the action of the second compression spring 325, the second pointed pin 324 is immediately inserted into the next second positioning hole 322. The second compression spring 325 is welded and fixed to the second pressure plate 323 and the transverse moving platform 304 at both ends, or the second compression spring 325 is only welded to the transverse moving platform 304. A spring bowl is set at the bottom of the second pressure plate 323, and the upper end of the second compression spring 325 is located inside the spring bowl.

[0029] When adjusting the position of the tamping hammer 309, the position of the horizontal moving platform 304 can be fixed so that it is at the second positioning hole 322 corresponding to the most side position. At the same time, in the initial state, the longitudinal moving platform 302 is also at the first positioning hole 314 corresponding to the most side position. The tamping hammer 309 is lifted to the highest position, that is, when the positioning sleeve 310 contacts the inner shaft sleeve 307, the tamping hammer 309 is released to fall freely. The tamping hammer 309 first moves longitudinally, that is, the longitudinal moving platform 302 is moved first, until one longitudinal row is tamped, and then the position of the horizontal moving platform 304 is adjusted once, and then the next row of tamping is completed.

[0030] The positioning sleeve 310 is provided with a first threaded hole in the radial direction, and the first threaded hole is internally threadedly connected with a first top screw 328 . The first top screw 328 can tighten the tamping hammer rod 308 to adjust the relative positions of the positioning sleeve 310 and the tamping hammer rod 308 in turn.

[0031] The inner sleeve 307 is slidably connected to the inner part of the outer sleeve 306. The outer sleeve 306 is provided with a second threaded hole in the radial direction. The inner part of the second threaded hole is threadedly connected to a second top screw 329. The second top screw 329 can tighten the inner sleeve 307. The relative position of the inner sleeve 307 and the outer sleeve 306 is adjustable, which can further increase the height adjustment range of the ramming hammer head 309.

[0032] The compaction mold 1 includes a bottom plate 330, on which four side plates 331 are arranged. The four side plates 331 and the bottom plate 330 enclose a square cavity.
