AI Technical Summary
[0004]虽然上述设备能对地基进行夯实操作,但是该设备不便于根据需求调控对地基夯实的强度和深度,同时上述设备在单位时间对地基进行夯实的效率也存在不足,因此现有的设备需要进行改进
[0022] First, this invention, by setting up a support device, allows the servo motor to drive the connecting turntable to rotate via an L-shaped planetary reducer during the cyclic compaction operation of the test site. The connecting turntable synchronously drives the ball bearing slide and the limiting shaft to rotate in a circular motion. This allows the limiting shaft to cyclically drive the guide rail to move up and down during the circular rotation. Simultaneously, the guide rail can synchronously drive the fixed slide on the side to move up and down. This allows the fixed slide to synchronously drive the compaction device on the other side to move up and down through the meshing of the transmission rack and spur gear. The two sets of compaction devices can then alternately compact the interior of the test site using rammed earth blocks, effectively improving the efficiency of compacting the foundation of the test site.

Description
Technical Field
[0001] This invention relates to the field of foundation construction technology, specifically a foundation compaction construction method. Background Technology
[0002] During construction, compacting the foundation is a common construction operation. Foundation compaction helps improve shear properties to prevent shear damage, strengthens the shear strength of the foundation, and prevents arching of the bottom of the pit due to insufficient bearing capacity, thus improving water retention properties.
[0003] According to Chinese Patent Publication No. CN214005648U, a foundation compaction device for building construction is disclosed, including a base. A support frame is fixedly connected to the top surface of the middle part of the base. A first clearance groove is opened on the inner side of the middle part of the base. A compaction plate is set on the top of the first clearance groove. An electric hydraulic rod is fixedly installed in the middle of the top surface of the compaction plate. The middle part of the electric hydraulic rod is fixedly sleeved on the inner side of the top of the support frame. A mud scraping mechanism is set on one side of the compaction plate. This utility model uses a first small servo motor inside the mud scraping mechanism to drive the scraper to automatically scrape mud on the bottom surface of the compaction mechanism formed by the electric hydraulic rod, the compaction plate, and the support frame. Moreover, the mud scraping operation is carried out during the working interval of the compaction mechanism, without the need for deliberate stopping. Thus, while replacing manual labor, it further improves the working efficiency and quality of the device.
[0004] Although the aforementioned equipment can compact the foundation, it is not convenient to adjust the intensity and depth of compaction according to needs. In addition, the efficiency of the equipment in compacting the foundation per unit time is also insufficient. Therefore, the existing equipment needs to be improved. Summary of the Invention
[0005] To address the problems in the prior art, the present invention provides a foundation compaction construction method.
[0006] The technical solution adopted by this invention to solve its technical problem is: a foundation compaction construction method, characterized by comprising the following steps:
[0007] S1. Level the test site. Before the test compaction, clean up all kinds of debris such as garbage in the test site. At the same time, dig drainage ditches in the test site to drain the test site.
[0008] S2. Perform predictive measurement operations, place various positioning tools at the test site to plan the test area, and use measuring equipment to calibrate, measure and record the test area of the selected test site.
[0009] S3. Compact the foundation of the test site by dropping a tamping hammer and using a combined tamping machine to repeatedly tamp the ground within the test site area.
[0010] S4. Evaluation of compaction effect: Measure the depth of multiple locations of the compaction pits in the test site and calculate the average value to obtain the average depth of the internal compaction pits.
[0011] Specifically, the tamping hammer is a 3m, 11t square hammer.
[0012] Specifically, the tamping hammer strikes 6 times, the full tamping energy is 1100KN, and the tamping hammer marks overlap by 1 / 4 of the hammer blows.
[0013] Specifically, the average penetration depth of the last two hammer blows is 60-70mm.
[0014] A foundation compaction construction device includes a transmission device, a support device, an arc-tooth synchronous pulley, a transmission guide shaft, an arc-tooth synchronous belt, a reduction motor, a protective top plate, and support rollers. A protective top plate for protection is fixedly installed at the center of the upper end face of the support device, and a transmission device is fixedly installed on the side of the upper end face of the support device opposite to the protective top plate. Support rollers for guidance are symmetrically and rotatably engaged on the lower end face of the support device. Arc-tooth synchronous pulleys for transmission are installed on the inner end faces of both sets of support rollers. The two sets of arc-tooth synchronous pulleys on the same side are meshed and connected by an arc-tooth synchronous belt. The two sets of arc-tooth synchronous pulleys on the same axis and the support rollers are fixedly connected by a transmission guide shaft. A reduction motor is fixedly installed on the side end face of the support device opposite to the transmission guide shaft.
[0015] The transmission device includes an L-shaped planetary reducer, a servo motor, a fixed clamping plate, a fixed slide groove, a ball bearing slide, a guide rail, a limiting shaft, a ball screw, a stepper motor, and a connecting turntable. An L-shaped planetary reducer for transmission is fixedly installed at the center of the rear end face of the fixed clamping plate, and a servo motor is fixedly installed at the center of the upper end face of the L-shaped planetary reducer. A connecting turntable for guidance is fixedly installed at the center of the front end face of the L-shaped planetary reducer, and a fixed slide groove is formed at the center of the inner end face of the connecting turntable. A ball screw is rotatably clamped at the center of the inner end face of the fixed slide groove, and a stepper motor is fixedly installed at the inner end face of the fixed slide groove, directly opposite the ball screw. A ball bearing slide is slidably connected to the inner end face of the connecting turntable via the ball screw thread. A limiting shaft is fixedly installed at the center of the side end face of the ball bearing slide, and a guide rail for guidance is slidably clamped to the outer end face of the limiting shaft.
[0016] Specifically, the support device includes a cylindrical spur gear, a compaction device, a guide slide shaft, a fixed clamping frame, a support side plate, a guide slide groove, a fixed rotating seat, a limiting plate, a guide slide plate, and a positioning slide. A fixed rotating seat for limiting is symmetrically arranged at the center of the lower end face of the limiting plate, and a fixed clamping frame is symmetrically arranged near the side of the lower end face of the limiting plate. Support side plates are symmetrically arranged at the center of the upper end face of the limiting plate, and a cylindrical spur gear is rotatably engaged between the two sets of support side plates. Two sets of positioning slide plates are symmetrically arranged on the upper end face of the limiting plate with the support side plate as the center. A guide slide groove is formed at the center of the inner end face of the positioning slide plate, and a guide slide shaft for guiding is fixedly arranged at the center of the inner end face of the guide slide groove. Two sets of compaction devices are slidably engaged on the inner end faces of the two sets of guide slide grooves through the guide slide shaft. A guide slide plate is symmetrically arranged on the inner end face of the limiting plate opposite the compaction device.
[0017] Specifically, the compaction device includes a transmission rack, a limiting guide seat, a support base, a rammed earth block, a compaction counterweight, a spring buffer shaft, and a fixed slide. The rear end face of the limiting guide seat is provided with three sets of transmission racks for transmission at equal intervals, and the support base is fixedly installed at the center of the lower end face of the three sets of transmission racks. The lower end face of the support base is symmetrically provided with a spring buffer shaft, and the lower end face of the two sets of spring buffer shafts is fixedly provided with a rammed earth block. The inner end face of the rammed earth block is detachably provided with a compaction counterweight. The side end face of the limiting guide seat is symmetrically provided with a fixed slide.
[0018] Specifically, the side end face of the guide slide rail is fixedly connected to the side of the fixed slide block. The limiting guide seat is adapted to the guide slide shaft through the fixed slide block and then slidably engaged with the inner end face of the guide slide groove. Both sets of opposing transmission racks are meshed with the cylindrical spur gear. When one set of compaction devices is raised, the compaction device can drive the other set of compaction devices to move down through the cylindrical spur gear, which facilitates the subsequent cyclical driving of the two sets of compaction devices to alternately compact the test site, thereby improving compaction efficiency.
[0019] Specifically, the rammed earth block is slidably engaged with the inner end face of the limiting plate via the guide slide plate. The internal opening length of the guide slide rail is greater than the diameter of the connecting turntable, and the diameter of the limiting rotating shaft is equal to the opening width of the guide slide rail. The limiting rotating shaft can rotate circumferentially, thereby cyclically driving the guide slide rail to move up and down, thus facilitating the subsequent provision of sufficient power by the guide slide rail for the compaction device to compact the test site, improving the compaction efficiency.
[0020] Specifically, a support plate is fixedly installed on the upper surface of both sets of guide slides, and a protective front plate is fixedly installed on the upper surface of both sets of support plate.
[0021] The beneficial effects of this invention are:
[0022] First, this invention, by setting up a support device, allows the servo motor to drive the connecting turntable to rotate via an L-shaped planetary reducer during the cyclic compaction operation of the test site. The connecting turntable synchronously drives the ball bearing slide and the limiting shaft to rotate in a circular motion. This allows the limiting shaft to cyclically drive the guide rail to move up and down during the circular rotation. Simultaneously, the guide rail can synchronously drive the fixed slide on the side to move up and down. This allows the fixed slide to synchronously drive the compaction device on the other side to move up and down through the meshing of the transmission rack and spur gear. The two sets of compaction devices can then alternately compact the interior of the test site using rammed earth blocks, effectively improving the efficiency of compacting the foundation of the test site.
[0023] Second, by setting up a transmission device, when adjusting the compaction strength and height, the stepper motor can drive the ball slide and the limiting shaft to move inside the fixed slide groove through the ball screw, thereby adjusting the distance between the limiting shaft and the center of the connecting turntable, and thus adjusting the distance of the guide rail to move up and down in cycles. This allows for adaptive control of the compaction height and strength of the rammed earth block, effectively improving the adaptability of the equipment's compaction performance.

[0038] like Figure 1-7 As shown, a foundation compaction construction method of the present invention is characterized by comprising the following steps:

A limit shaft 17 is fixedly installed at the center of the side end face of the ball slide 15. A guide rail 16 for guiding is slidably engaged at the outer end face of the limit shaft 17.
[0048] The support device 2 includes a cylindrical spur gear 21, a compaction device 22, a guide slide shaft 23, a fixed clamping bracket 24, a support side plate 25, a guide slide groove 26, a fixed rotating seat 27, a limiting clamping plate 28, a guide slide plate 29, and a positioning slide 210. A fixed rotating seat 27 for limiting is symmetrically arranged at the center of the lower end face of the limiting clamping plate 28, and a fixed clamping bracket 24 is symmetrically arranged near the side of the lower end face of the limiting clamping plate 28. Support side plates 25 are symmetrically arranged at the center of the upper end face of the limiting clamping plate 28, and are located between the two sets of support side plates 210. A cylindrical spur gear 21 is rotatably engaged between the 5. Two sets of positioning slides 210 are symmetrically arranged on the upper end face of the limiting plate 28 with the supporting side plate 25 as the center. A guide groove 26 is opened at the center of the inner end face of the positioning slide 210. A guide slide shaft 23 for guidance is fixedly arranged at the center of the inner end face of the guide slide groove 26. Two sets of compaction devices 22 are slidably engaged on the inner end face of the two sets of guide slide grooves 26 through the guide slide shaft 23. A guide slide plate 29 is symmetrically arranged on the inner end face of the limiting plate 28 opposite to the compaction device 22.
[0049] The compaction device 22 includes a transmission rack 221, a limiting guide seat 222, a support base 223, a tamping block 224, a compaction counterweight 225, a spring buffer shaft 226, and a fixed slide 227. Three sets of transmission racks 221 for transmission are equidistantly arranged on the rear end face of the limiting guide seat 222, and the support base 223 is fixedly installed at the center of the lower end face of the three sets of transmission racks 221. The lower end face of the support base 223 is symmetrically arranged with a spring buffer shaft 226. The tamping block 224 is fixedly arranged on the lower end face of the two sets of spring buffer shafts 226, and the compaction counterweight 225 is detachably arranged on the inner end face of the tamping block 224. The fixed slide 227 is symmetrically arranged on the side end face of the limiting guide seat 222.
[0050] The side end face of the guide slide rail 16 is fixedly connected to the side of the fixed slide seat 227. The limiting guide seat 222 is adapted to the guide slide shaft 23 through the fixed slide seat 227 and then slidably engaged with the inner end face of the guide slide groove 26. Both sets of opposing transmission racks 221 are meshed with the cylindrical spur gear 21. When one set of compaction devices 22 is raised, the compaction device 22 can drive the other set of compaction devices 22 to move down through the cylindrical spur gear 21, which facilitates the subsequent cyclical driving of the two sets of compaction devices 22 to alternately compact the test site, thereby improving the compaction efficiency.
[0051] The rammed earth block 224 is slidably engaged with the inner end face of the limiting plate 28 via the guide slide plate 29.

This facilitates the subsequent provision of sufficient power by the guide slide rail 16 for the ramming device 22 to ram the test site, thus improving the ramming efficiency.
[0052] The working principle of Example 1 is as follows: During use, the user can simultaneously start the reduction motor 6 and the servo motor 12 through an external control device. During displacement operations, the reduction motor 6 drives the transmission guide shaft 4 to rotate, which in turn drives the arc-shaped toothed synchronous belt pulley 3 and the support roller 8 to rotate. The support roller 8, located on the same side, rotates synchronously through the meshing of the arc-shaped toothed synchronous belt pulley 3 and the arc-shaped toothed synchronous belt 5, thereby driving the support device 2 to move. During the compaction operation of the test site foundation, the servo motor 12 drives the L-shaped planetary reducer 11 to rotate, which in turn drives the connecting turntable 110 to rotate in a circular motion. The connecting turntable 110 synchronously drives the ball bearing slide 1... 5. The limiting shaft 17 rotates in a circle. At this time, the limiting shaft 17 can slide and displace with the guide rail 16, thereby driving the guide rail 16 to move up and down in a cycle on the upper part of the limiting plate 28. The guide rail 16 can drive the limiting guide seat 222 to move down. The limiting guide seat 222 can drive the transmission rack 221 to move down. At the same time, the transmission rack 221 can mesh with the cylindrical spur gear 21, thereby synchronously driving the compaction device 22 on the other side to move up and down. The two sets of transmission racks 221 can move up and down alternately under the drive of the cylindrical spur gear 21, so that the two sets of transmission racks 221 can drive the rammed earth block 224 to perform a cyclic compaction operation on the area to be compacted through the support base 223.
