[0002] In the initial stage of engineering construction, it is necessary to ram the construction ground so that the soil layer within a certain depth below the construction ground reaches a dense state, improve the bearing capacity of the foundation, and eliminate the collapsibility of collapsible foundations; however, it is found through investigation that the existing ramming equipment all adopts an intermittent pressure plate structure, and it is necessary to calculate the ramming movement amount of each step during the actual ramming process, and the process is relatively cumbersome. At the same time, in the intermittent ramming, some parts fail to achieve a sufficient ramming effect, resulting in ramming omission and affecting the safety of later building construction.

Specific embodiments

[0020] Please refer to Figure 1 , in the embodiment of the present invention, a ground ramming device for building construction includes: an outer frame column 1, on one side of the outer frame column 1, a connecting member 11 is fixed, and it can be fixed to an external roller through the connecting member 11. An installation cavity is provided inside the outer frame column 1. A self - vibrating pressing component 3 is vertically and slidably limited below the installation cavity. The self - vibrating pressing component 3 can contact the building ground and actively ram the ground. Above the installation cavity, a gravity impact component 2 is provided. The gravity impact component 2 can provide vertical impact potential energy to the self - vibrating pressing component 3 so that the self - vibrating pressing component 3 can achieve a continuous ramming effect. That is to say, the self - vibrating pressing component can actively ram at a certain height during displacement, while the gravity impact component can continuously provide impact potential energy, thereby realizing the continuity of ramming.

[0021] In this embodiment, the self - vibrating pressing component 3 includes: a fixed shaft cylinder 31, which is vertically slidably arranged in the installation cavity of the outer frame column 1. A piston 32 is hermetically and slidably arranged inside the fixed shaft cylinder 31, and its upper end is horizontally connected to a main air supply pipe 33. One end of the main air supply pipe 33 is communicated with an external booster pump (not shown in the figure). Below the fixed shaft cylinder 31, a ramming plate 35 is coaxially arranged. A plurality of limiting rods 37 are vertically fixed on the ramming plate 35. The piston 32 is slidably connected to each of the limiting rods 37 through a strengthening pillar. An inner spring is sleeved below the strengthening pillar on the limiting rod 37. A plurality of strip - shaped discharge holes are circumferentially opened on the side wall of the fixed shaft cylinder 31.

[0022] As a preferred embodiment, an outer sleeve 38 is also sleeved and fixed on the fixed shaft cylinder 31. A ring plug 39 is slidably arranged in the outer sleeve 38. And a flow guide ring 4 is hermetically and slidably arranged below the outer sleeve 38 on the fixed shaft cylinder 31. The flow guide ring 4 is fixed to the ring plug 39 through a support rod. A plurality of air flow holes corresponding to the strip-shaped row holes are arranged on the flow guide ring 4. A plurality of first return springs 34 are connected below the piston 32 in the fixed shaft cylinder 31. Wherein, when the air supply main pipe continuously supplies air to increase the pressure, the piston slides vertically and crosses the strip-shaped row holes, and the first return springs are gradually compressed. At this time, the air flow quickly discharges from the strip-shaped row holes. The first return springs elastically reset and drive the piston to displace in the reverse direction. Therefore, the external booster pump can drive the piston to reciprocate under continuous pressurized exhaust to achieve the high-speed ramming effect. Especially, the vertical sliding action of the flow guide ring is used to adjust the position of the air flow holes on the flow guide ring relative to the strip-shaped row holes (the strip-shaped row holes and the air flow holes are always communicated), so as to adjust the reset height of the piston and control the ramming intensity.

[0023] In this embodiment, a pressure-bearing seat 36 is fixed directly below the strengthening strut on the ram plate 35. And a guide seat 5 is embedded and fixed in the installation inner cavity of the outer frame column 1. A casting plate frame 51 is vertically slidably arranged in the guide seat 5. The lower part of the casting plate frame 51 is connected to the fixed shaft cylinder 31 through a plurality of connecting columns 52. A plurality of second return springs 53 are connected between the casting plate frame 51 and the guide seat 5. A pressure-sharing seat 54 is also installed on the casting plate frame 51. The gravity impact assembly can provide impact potential energy to the self-vibrating pressure assembly through the pressure-sharing seat to ensure the stability of the main body.

[0024] In this embodiment, the gravity impact assembly 2 includes: an air injection inner cavity 21, which is circumferentially distributed in the installation inner cavity of the outer frame column 1. Plunger rods 22 are slidably arranged in the air injection inner cavities 21. A counterweight seat 23 is fixed below each of the plunger rods 22. A plurality of air vents 24 are arranged on the outer frame column 1 at the installation inner cavity. And a circulation hood 27 is fixed on the outer frame column 1. The circulation hood 27 is communicated with each of the air vents 24. An air supply pump 26 is fixed outside the outer frame column 1 through a connecting frame. The air supply pump 26 is connected to the circulation hood 27. That is to say, the air supply pump can supply air to increase the pressure to the air injection inner cavities through each air vent, so as to correspondingly drive the vertical displacement of each counterweight seat.

[0025] In this embodiment, a plurality of booster pipes 25 are also vertically connected below the circulation hood 27 on the outer frame column 1. The booster pipes 25 can be correspondingly communicated with each of the air injection inner cavities 21.

[0026] As a preferred embodiment, a control valve (not shown in the figure) is provided in each of the vent ports 24, and a one-way exhaust member (not shown in the figure) is provided on the air injection cavity 21 for discharging the air flow in the air injection. In particular, during use, the control valves on each vent port are opened one by one in sequence. At this time, the plunger rod in the air injection cavity slides correspondingly and forms an impact by the counterweight seat. After the stamping is completed, the corresponding booster pipe can drive the plunger to reset. At this time, the next control valve is opened, so that the next counterweight seat can perform an impact, and the interval time is short (negligible).

[0027] In this embodiment, a compression spring is further provided above the plunger rod 22 to further increase the stamping potential energy under compression.

[0028] Specifically, the external roller can control the vertical erection of the outer frame column. At this time, the external booster pump can supply air and increase the pressure to the fixed shaft cylinder. The ramming plate is continuously impacted by the pressure-bearing seat to form reciprocating ramming on the building ground. At the same time, the counterweight seat in the gravity impact assembly can form impact potential energy during vertical displacement and impact and press down on the self-vibration pressing assembly through the pressure-dividing seat. Among them, multiple counterweight seats can provide impact ramming effects in sequence (circumferential sequence or diagonal sequence), with a short interval time and can achieve continuous ramming effects, avoiding incomplete ramming in the area.

[0029] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
