Description

Technical Field

[0001] The present invention relates to the technical field of rammed earth foundation, and in particular to a rammed earth foundation processing device and method for building construction. Background Art

[0002] During the construction process, the foundation generally needs to be backfilled with rammed earth. The quality of the backfilled rammed earth directly affects the strength of the foundation, as well as the service life and safety of the superstructure. The effect and quality of the rammed earth of the foundation are directly affected by the way the backfilled earth is treated. Therefore, the treatment method of the rammed earth of the foundation is one of the important processes in the rammed earth process.

[0003] In existing foundation ramming devices, the treatment process, backfill process, and compaction process are generally performed separately. Although this approach has certain advantages, it cannot shorten the construction period and cannot further improve the treatment efficiency, backfill efficiency, and compaction efficiency. At the same time, existing foundation ramming devices cannot effectively compact sloped base surfaces. Therefore, there is a need for a foundation ramming device and method for construction that can perform the treatment process, backfill process, and compaction process simultaneously and effectively compact sloped base surfaces to address the shortcomings of existing foundation ramming devices and methods.

[0004] For example, the patent with announcement number CN111691393B provides a saline soil foundation treatment device, which includes a base car body, a tamping device, a bulldozer, a transmission device and an anchoring device; the tamping device is used for compacting the foundation, and the bulldozer is used for rapid backfilling of backfill soil. This application enables bulldozing and tamping to be carried out simultaneously, and in the process of retracting the bulldozer, the anchoring device is driven at the same time for fixed support, and the new anchoring structure is more stable; however, this solution can only simply push and fill the backfill soil, and is unable to crush and screen the soil blocks in the backfill soil at the same time, nor is it able to properly change the humidity of the backfill soil during the backfill process; the existing backfill soil processing solution requires a longer conveyor belt to transport the backfill soil, which cannot effectively save the volume of the processing system, and cannot transport the processing device together with the backfill tamping device; this solution cannot realize the integration of the processing process, backfill process and tamping process; this solution cannot perform effective tamping when facing a slope base surface, and cannot realize the tilting and folding function, thereby failing to reduce the overall height of the device and improving the passability of the tamping device.

[0015] A method for treating rammed earth foundation for building construction comprises the following steps:

[0016] Step 1: The first electric push rod on the moving device drives the plunger to slide inside the hydraulic cylinder, and the plunger drives the hydraulic oil in the hydraulic cylinder to be pressed into the hydraulic pipeline of the rotating assembly, and then enters between the hydraulic baffle and the rotating baffle from the hydraulic pipeline. At this time, the pressure of the hydraulic oil drives the rotating baffle and the rotating shaft to rotate, and the rotating shaft drives the linkage rotating wheel to rotate. The linkage rotating wheel drives the arc slide to rotate through the linkage gear and linkage slot, and the arc slide drives the support frame to flip forward to a vertical state, realizing the conversion of the working mode of the support device;

[0017] Step 2: When the support frame is in a vertical state, the servo motor drives the second pulley to rotate, and the servo motor drives the first pulley on the card-off assembly to rotate through the transmission belt, and the first pulley drives the card-off turntable to rotate, and the card-off turntable drives the milling shell to rotate around the periphery of the screening assembly through the card-off slider and the milling groove, and the milling shell drives the milling blades to rotate around the periphery of the screening drum, so that the milling blades and the screening drum grind the backfill soil, and at the same time, the milling wheel rolls on the upper surface of the support ring, and the milling wheel drives the conical runner and the spiral blades to rotate inside the milling shell, which will drive the backfill soil from the screening hole into the inside of the screening drum, and then fall from the inside of the screening drum to the inside of the compacting screw, thereby improving the efficiency of stirring and advancing the backfill soil;

[0018] Step 3: When the milling shell rotates forward, the nut turntable drives the tamping screw to lift upward. When the tamping screw is lifted to the highest position, the tamping linkage plate drives the disengagement block to disengage from the milling groove. At this time, the disengagement block is stuck in the disengagement groove at the lower end of the disengagement turntable. Then the tamping disk drives the tamping screw to fall freely. The tamping screw drives the nut turntable and the milling shell to rotate in the opposite direction, realizing the secondary processing function of the milling device and the tamping function of the tamping device.

[0019] Step 4: As the compacting screw is lifted upward, the limiting pillar in the screening cylinder is inserted into the interior of the compacting screw and presses the backfill soil in the compacting screw downward. The pressure generated drives the soil drop plate to separate from the interior of the compacting plate, so that the lower end of the compacting plate is connected to the outside world. The backfill soil then falls to the ground, completing the backfilling of the backfill soil. At the same time, an appropriate amount of water or other reagents is added from the upper end of the screening cylinder to change the moisture content and viscosity of the backfill soil.

[0020] Step 5: When the tamping disc collides with the ground, the tamping disc and the tamping screw will vibrate. The vibration of the tamping screw is transmitted to the release disc through the nut disc and the grinding shell, and then transmitted from the release disc to the release groove, causing the release slider to fall out of the release groove and reinsert into the grinding groove.

[0021] Step 6: While the compacting device is compacting the soil, the vehicle drives the mobile base on the mobile device to move forward, and then the mobile base drives the rolling drum to roll the ground. The mobile base also drives the compacting device to move forward to achieve the compaction function in a mobile state;

[0022] Step 7: Before step 1, the support frame is in an inclined lying state, and the grinding device and the tamping device are also in an inclined lying state. Then the second electric push rod on the positioning assembly drives the positioning rod to move inward, so that the positioning rod is inserted into the support hole on the side of the arc-shaped slide to achieve temporary positioning;

[0023] Step 8: Then remove the tamping disc from the tamping device, and fix an extension rod on the lower end of the tamping screw, and then re-fix the tamping disc on the lower end of the extension rod to achieve the tamping function on the slope.

[0024] The beneficial effects of the present invention compared with the prior art are:

[0025] (1) The milling device drives the milling shell to rotate through the snap-off assembly, and the milling shell drives the milling blades to rotate, so that the milling blades and the screening drum grind the backfill soil. At the same time, the milling wheel will roll on the upper surface of the support ring and drive the conical wheel and spiral blades to rotate, thereby improving the efficiency of stirring and pushing the backfill soil.

[0026] (2) When the milling shell rotates in the forward direction, the nut turntable drives the tamping screw to lift upward. When the tamping screw is lifted to the highest position, the tamping linkage plate drives the card block to disengage from the milling groove. Then the tamping plate drives the tamping screw to fall freely. The tamping screw drives the nut turntable and the milling shell to rotate in the opposite direction, realizing the secondary processing function of the milling device and the tamping function of the tamping device at the same time.

[0027] (3) When the support frame is in an inclined lying state, the grinding device and the tamping device will also be in an inclined lying state. Then the second electric push rod on the positioning assembly drives the positioning rod to move inward, so that the positioning rod is inserted into the support hole on the side of the arc-shaped slide bar to realize the temporary positioning function. Then the tamping disc on the tamping device is removed, and an extension rod is fixed to the lower end of the tamping screw. Then the tamping disc is re-fixed and installed on the lower end of the extension rod to realize the tamping function of the slope. BRIEF DESCRIPTION OF THE DRAWINGS

When adding backfill soil to the milling shell 201, the backfill soil is first transported to the first feed pipe 205 in the connecting frame 206, and then enters between the milling shell 201 and the screening drum 211 through the first feed pipe 205 and the second feed pipe 214.

[0057] A method for treating rammed earth foundation for building construction comprises the following steps:

[0058] Step 1: The first electric push rod 507 on the moving device 5 drives the plunger 508 to slide inside the hydraulic cylinder 509. The plunger 508 drives the hydraulic oil in the hydraulic cylinder 509 to be pressed into the hydraulic pipe 517 of the rotating assembly 512. Then, the hydraulic oil enters between the hydraulic baffle 518 and the rotating baffle 520 from the hydraulic pipe 517. At this time, the pressure of the hydraulic oil drives the rotating baffle 520 and the rotating shaft 519 to rotate. The rotating shaft 519 drives the linkage rotating wheel 506 to rotate. The linkage rotating wheel 506 drives the arc slide 409 to rotate through the linkage gear 505 and the linkage slot 410. The arc slide 409 drives the support frame 406 to flip forward to a vertical state, realizing the conversion of the working mode of the support device 4;

[0059] Step 2: When the support frame 406 is in a vertical state, the servo motor 405 drives the second pulley 404 to rotate, and the servo motor 405 drives the first pulley 101 on the card-off assembly 1 to rotate through the transmission belt 403. The first pulley 101 drives the card-off turntable 102 to rotate. The card-off turntable 102 drives the grinding shell 201 to rotate around the periphery of the screening assembly 204 through the card-off slider 103 and the grinding groove 203. The grinding shell 201 drives the grinding blades 210 to rotate in the screening cylinder. The outer periphery of the grinding wheel 211 rotates, causing the grinding blades 210 and the screening drum 211 to grind the backfill soil. At the same time, the grinding wheel 202 rolls on the upper surface of the support ring 402. The grinding wheel 202 drives the conical runner 208 and the spiral blades 209 to rotate inside the grinding housing 201, which drives the backfill soil into the screening drum 211 through the screening holes 212. Then, the backfill soil falls from the inside of the screening drum 211 to the inside of the compacting screw 304, thereby improving the efficiency of stirring and advancing the backfill soil.

[0060] Step 3: When the milling shell 201 rotates forward, the nut rotary disc 207 drives the tamping screw 304 to lift upward. When the tamping screw 304 is lifted to the highest position, the tamping linkage plate 302 drives the disengagement block 105 to disengage from the milling groove 203. At this time, the disengagement block 105 is stuck in the disengagement groove 104 at the lower end of the disengagement rotary disc 102. Then, the tamping disc 305 drives the tamping screw 304 to fall freely. The tamping screw 304 drives the nut rotary disc 207 and the milling shell 201 to rotate in the opposite direction, realizing the secondary processing function of the milling device 2 and the tamping function of the tamping device 3.

[0061] Step 4: As the tamping screw 304 is lifted upward, the limiting pillars 216 in the screening cylinder 211 are inserted into the interior of the tamping screw 304 and press the backfill soil in the tamping screw 304 downward. The pressure generated drives the soil drop plate 307 to separate from the interior of the tamping plate 305, so that the lower end of the tamping plate 305 is connected to the outside. The backfill soil then falls to the ground, completing the backfilling of the backfill soil. At the same time, a proper amount of water or other reagents are added from the upper end of the screening cylinder 211 to change the moisture content and viscosity of the backfill soil.

[0062] Step 5: When the tamping disc 305 collides with the ground, the tamping disc 305 and the tamping screw 304 vibrate. The vibration of the tamping screw 304 is transmitted to the latching disc 102 through the nut disc 207 and the grinding housing 201, and then transmitted from the latching disc 102 to the latching groove 104, causing the latching slider 103 to fall out of the latching groove 104 and reinsert into the grinding groove 203.

[0063] Step 6: While the compacting device 3 is compacting the soil, the mobile base 501 on the mobile device 5 is driven forward by the vehicle. Then, the mobile base 501 drives the rolling drum 511 to roll the ground. The mobile base 501 also drives the compacting device 3 forward to achieve the compaction function in the mobile state.

[0064] Step 7: Before step 1 is performed, the support frame 406 is in an inclined lying state. At this time, the grinding device 2 and the tamping device 3 are also in an inclined lying state. Then, the second electric push rod 514 on the locking assembly 504 drives the locking rod 513 to move inward, so that the locking rod 513 is inserted into the support hole 411 on the side of the arc-shaped slide 409, thereby achieving temporary locking.

[0065] Step 8: Then remove the tamping disc 305 on the tamping device 3, and fix an extension rod on the lower end of the tamping screw 304, and then re-fix the tamping disc 305 on the lower end of the extension rod to achieve the tamping function on the slope.

[0066] The present invention is not limited to the above-mentioned specific implementation methods. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work are all within the scope of protection of the present invention.

6. A method for treating rammed earth foundation for construction, characterized in that: The rammed earth treatment device for construction as claimed in claim 5 comprises the following steps: Step 1: The first electric push rod (507) on the moving device (5) drives the plunger (508) to slide inside the hydraulic cylinder (509), and the plunger (508) drives the hydraulic oil in the hydraulic cylinder (509) to be pressed into the hydraulic pipe (517) of the rotating assembly (512), and then enters between the hydraulic baffle (518) and the rotating baffle (520) from the hydraulic pipe (517). At this time, the pressure of the hydraulic oil drives the rotating baffle (520) and the rotating shaft (519) to rotate, and the rotating shaft (519) drives the linkage wheel (506) to rotate. The linkage wheel (506) drives the arc slide (409) to rotate through the linkage spline (505) and the linkage slot (410), and the arc slide (409) drives the support frame (406) to flip forward to a vertical state, thereby realizing the conversion of the working mode of the support device (4); Step 2: When the support frame (406) is in a vertical state, the servo motor (405) drives the second pulley (404) to rotate, and the servo motor (405) drives the first pulley (101) on the snap-off assembly (1) to rotate through the transmission belt (403), and the first pulley (101) drives the snap-off turntable (102) to rotate, and the snap-off turntable (102) drives the grinding shell (201) to rotate on the periphery of the screening assembly (204) through the snap-off slider (103) and the grinding groove (203), and the grinding shell (201) drives the grinding blade (210) to rotate on the periphery of the screening assembly (204). The periphery of the screening cylinder (211) rotates, causing the grinding blades (210) and the screening cylinder (211) to grind the backfill soil. At the same time, the grinding wheel (202) rolls on the upper surface of the support ring (402). The grinding wheel (202) drives the conical wheel (208) and the spiral blades (209) to rotate inside the grinding shell (201), driving the backfill soil to enter the interior of the screening cylinder (211) through the screening hole (212), and then fall from the interior of the screening cylinder (211) to the interior of the compacting screw (304), thereby improving the efficiency of stirring and advancing the backfill soil. Step 3: When the milling shell (201) rotates forward, the nut turntable (207) drives the tamping screw (304) to lift upward. When the tamping screw (304) is lifted to the highest position, the tamping linkage plate (302) drives the snap-off block (105) to disengage from the milling groove (203). At this time, the snap-off block (105) is stuck in the snap-off groove (104) at the lower end of the snap-off turntable (102). Then, the tamping disk (305) drives the tamping screw (304) to fall freely. The tamping screw (304) drives the nut turntable (207) and the milling shell (201) to rotate in the opposite direction, thereby realizing the secondary processing function of the milling device (2) and the tamping function of the tamping device (3); Step 4: During the upward lifting of the tamping screw (304), the limiting support (216) in the screening cylinder (211) is inserted into the interior of the tamping screw (304) and presses the backfill soil in the tamping screw (304) downward. The generated pressure drives the soil drop plate (307) to separate from the interior of the tamping plate (305), so that the lower end of the tamping plate (305) is connected to the outside world. Then, the backfill soil falls to the ground, and the backfill soil is backfilled. At the same time, a proper amount of water or other reagents is added from the upper end of the screening cylinder (211) to change the water content and viscosity of the backfill soil. Step 5: When the tamping disc (305) collides with the ground, the tamping disc (305) and the tamping screw (304) vibrate. The vibration of the tamping screw (304) is transmitted to the latching disc (102) through the nut rotary disc (207) and the grinding shell (201), and then transmitted from the latching disc (102) to the latching groove (104), causing the latching slider (103) to fall out of the latching groove (104) and be reinserted into the grinding groove (203); Step 6: While the tamping device (3) is tamping the soil, the mobile base (501) on the mobile device (5) is driven forward by the vehicle, and then the mobile base (501) drives the rolling cylinder (511) to roll the ground. The mobile base (501) also drives the tamping device (3) to move forward, thereby realizing the tamping function in the mobile state; Step 7: Before step 1 is performed, the support frame (406) is in an inclined lying state, and at this time, the grinding device (2) and the tamping device (3) are also in an inclined lying state, and then the second electric push rod (514) on the locking assembly (504) drives the locking rod (513) to move inward, so that the locking rod (513) is inserted into the support hole (411) on the side of the arc-shaped slide (409), thereby achieving temporary locking; Step 8: The tamping disc (305) on the tamping device (3) is then disassembled, and an extension rod is fixedly installed at the lower end of the tamping screw (304), and the tamping disc (305) is re-fixed and installed at the lower end of the extension rod to achieve the tamping function on the slope.
