[0002] High-pressure jet grouting piles use high-pressure rotating nozzles to spray cement slurry into the soil layer and mix it with the soil to form a continuous overlapping cement reinforcement body. The construction occupies a small area, has low vibration and low noise, but it is easy to pollute the environment and has a high cost. It is not suitable for special soils that cannot solidify the sprayed slurry.

[0003] In order to effectively prevent production safety accidents caused by illegal operations of pile-driving machinery, it is necessary to carry out anti-dumping reinforcement on the high-pressure rotary jet pile machine during construction to avoid the high-pressure rotary jet pile machine from invading the municipal road outside the enclosure when it overturns, so as to ensure construction safety.

[0015] The structure of the resistance component is as follows: it includes an air bag arranged on the outer wall of the counterweight block, and the air bag is higher than the soil insertion rod.

[0016] The inner walls on both sides of the counterweight block are provided with connecting grooves, and the connecting grooves on both sides are connected with connecting pipes connected with the airbags. Movable plates are fitted and connected to the inner walls of the connecting grooves on both sides, and connecting frames are provided on the movable plates on both sides. The connecting frames on both sides are respectively connected to the sliding rods on both sides, and the connecting grooves are located above the sliding rails.

[0017] Both sides of the counterweight block are connected with lifting components, and the lifting components are provided with moving components.

[0018] The structure of the lifting assembly is as follows: it includes a fixed frame, a through slot 1 is vertically opened on a side of the fixed frame away from the counterweight block, a through slot 2 is vertically opened on a side of the fixed frame close to the counterweight block, a fixed rod is slidably connected to the through slot 2, the fixed rod is connected to the counterweight block, the fixed rod is screwed to a screw rod 1, and a rotating shaft 1 connected to the fixed frame through bearings is provided on both the top and bottom sides of the screw rod 1.

[0019] The structure of the moving component is as follows: it includes a second screw rod, a second rotating shaft is provided on both the top and bottom sides of the second screw rod, and the second rotating shaft is connected to the fixed frame through a bearing, a wheel frame is screwed on the second screw rod, and universal wheels are provided on the front and rear sides of the bottom of the wheel frame, gears are provided on the first rotating shaft and the second rotating shaft, and the gears on both sides are meshed with each other, and a motor is provided on the fixed frame, and the output shaft of the motor is connected to the second rotating shaft.

[0020] A support rod is arranged between the fixing frames on both sides, and a handle is arranged on one of the fixing frames.

[0021] A method for preventing a high-pressure rotary jet pile machine from tipping over a support, comprising the following operation procedures:

[0022] Step 1: Pre-embed the steel plate to fix the steel support, and then tightly connect the steel support to the pile driver through the steel wire rope. When the pile driver tilts, the steel support can stabilize the pile driver to prevent it from overturning and ensure construction safety;

[0023] Step 2: When encountering strong winds and bad weather, pre-dig a pit on the ground around the pile driver that matches the outer diameter of the counterweight, then insert the counterweight into the pit, and then place the steel plate at the bottom of the steel support on the counterweight. The steel plate and the counterweight can be fixed together by screws and nuts, which increases the counterweight of the steel support and the depth of insertion into the soil. In this way, when encountering strong winds, the stability of the steel support can be improved, thereby better stabilizing the pile driver;

[0024] Step three: When the steel plate and the counterweight are fixed, the connecting rod squeezes the mounting frame, so that the reset spring stretches, and then the inclined rod squeezes the slide plate, so that the soil insertion rods on both sides move to the side away from each other, so that they can be inserted into the soil laterally, making it difficult for the counterweight to move upward from the soil pit, thereby further improving the stability of the steel support and further stabilizing the pile driver. Since the soil pit is difficult to be in close contact with the outer wall of the counterweight, an air bag is arranged on the outer wall of the counterweight. When the mounting frame moves downward, the slide rod drives the connecting frame to move downward, so that the movable plate squeezes the air in the connecting groove, and then inflates the air bag through the connecting pipe, so that the air bag expands and fills the gap between the counterweight and the soil pit, increasing the contact area with the soil pit, increasing the friction, thereby further improving the stability of the steel support;

[0025] Step 4: After the counterweight is inserted into the pit, the bottom of the fixed frame is supported by the ground. When the pile driver needs to be moved, loosen the wire rope, then remove the nut, and move the steel support and the steel plate upward, so that the reset spring drives the mounting frame to reset upward, so that the airbag can be deflated, and the soil insertion rod is retracted into the counterweight. Then, the fixed rod is driven upward by the lifting assembly to move the counterweight upward and out of the pit. When the counterweight moves upward, the wheel frame drives the universal wheel to move downward, so that when the counterweight moves out of the pit, the universal wheel can contact the ground to lift the fixed frame, so that it is convenient to move the fixed frames on both sides and the counterweight in the middle to the next location of the pile driver construction for reinforcement through the handle and the support rod.

[0026] The beneficial effects of the present invention are as follows:

[0027] 1. The steel plate is embedded in advance to fix the steel support, and then the steel support is tightly connected to the pile driver through the steel wire rope. When the pile driver tilts, the steel support can stabilize the pile driver to prevent the pile driver from overturning and ensure construction safety;

[0028] 2. When encountering severe weather with strong winds, the steel plate is no longer pre-buried. Instead, a pit matching the outer diameter of the counterweight block is pre-dug on the ground around the pile driver. The counterweight block is then inserted into the pit, and the steel plate at the bottom of the steel support is placed on the counterweight block. The steel plate and the counterweight block can be fixed together by screws and nuts, which increases the counterweight of the steel support and the depth of soil insertion. Therefore, when encountering strong winds, the stability of the steel support can be improved, thereby better stabilizing the pile driver;

[0029] 3. When the steel plate and the counterweight are fixed, the connecting rod squeezes the mounting frame, so that the reset spring stretches, and then the inclined rod squeezes the slide plate, so that the soil insertion rods on both sides move to the side away from each other, so that they can be inserted into the soil horizontally, making it difficult for the counterweight to move upward from the soil pit, thereby further improving the stability of the steel support and further stabilizing the pile driver. Since the soil pit is difficult to be in close contact with the outer wall of the counterweight, an air bag is arranged on the outer wall of the counterweight. When the mounting frame moves downward, the slide bar drives the connecting frame to move downward, so that the movable plate squeezes the air in the connecting groove, and then inflates the air bag through the connecting pipe, so that the air bag expands and fills the gap between the counterweight and the soil pit, increasing the contact area between the soil pit and the friction force, thereby further improving the stability of the steel support;

[0030] 4. After the counterweight is inserted into the earth pit, the bottom of the fixed frame is supported by the ground. When the pile driver needs to be moved, loosen the wire rope, then remove the nut, and move the steel support and the steel plate upward, so that the reset spring drives the mounting frame to reset upward, so that the air bag can be deflated, and the soil insertion rod is retracted into the counterweight. Then, the fixed rod is driven upward by the lifting assembly to move the counterweight upward out of the earth pit. When the counterweight moves upward, the wheel frame drives the universal wheel to move downward, so that when the counterweight moves out of the earth pit, the universal wheel can contact the ground to lift the fixed frame, so that it is convenient to move the fixed frames on both sides and the counterweight in the middle to the next location of the pile driver construction for reinforcement through the handle and the support rod.

[0038] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0039] Embodiment 1:

[0040] Reference Figure 1 , a high-pressure rotary jet pile driver anti-dumping bracket, comprising a pile driver 1;

[0041] Steel support;

[0042] The steel support comprises two steel sections 1 2, both ends of the bottom of the two steel sections 1 2 are provided with steel sections 2 3, and opposite sides of the two steel sections 1 2 are evenly provided with steel sections 3 5;

[0043] A steel wire rope 6 is connected between one of the steel sections 5 and the pile driver 1;

[0044] The bottom of the steel section 2 3 is provided with a pre-embedded steel plate 4.

[0045] The embedded steel plate 4 can fix the steel support, and then the steel support is tightly connected to the pile driver 1 through the steel wire rope 6. When the pile driver 1 tilts, the steel wire rope 6 pulls the pile driver 1, and the pile driver 1 can be stabilized by the steel support to prevent the pile driver 1 from overturning, thereby ensuring construction safety.

[0046] Embodiment 2:

[0047] Reference Figures 2 to 6 The bottom of the steel plate 4 is fitted and connected with a counterweight block 7, and screws 8 are arranged around the top of the counterweight block 7. The screws 8 vertically penetrate the steel plate 4, and a nut 9 screwed on the screw 8 is fitted and connected to the steel plate 4. The counterweight block 7 is provided with a fixing component and a resistance component.

[0048] When encountering severe weather with strong winds, the steel plate 4 is no longer embedded. Instead, a pit matching the outer diameter of the counterweight block 7 is pre-dug on the ground around the pile driver 1. The counterweight block 7 is then inserted into the pit, and the steel plate 4 is placed on the counterweight block 7. The steel plate 4 and the counterweight block 7 can be fixed together by screws 8 and nuts 9, so that the counterweight of the steel support and the depth of insertion into the soil can be increased, thereby improving the stability of the steel support when encountering strong winds, thereby better stabilizing the pile driver 1.

[0049] The fixing assembly includes a connecting rod 17 connected to the bottom of the steel plate 4, the bottom of the connecting rod 17 passes through the top of the counterweight block 7, and the bottom of the connecting rod 17 is closely connected to the mounting frame 12, and both sides of the top of the mounting frame 12 are provided with reset springs 16 connected to the top of the inner wall of the counterweight block 7, and both sides of the mounting frame 12 are provided with slide bars 11, and the inner walls of both sides of the counterweight block 7 are provided with slide rails 10 slidably connected to the slide bars 11, and the bottom of both sides of the mounting frame 12 are hinged with inclined rods 13, and the bottom of the inclined rods 13 is hinged with a slide plate 14 slidably connected to the inner wall of the bottom of the counterweight block 7, and the sides of the slide plates 14 on both sides are evenly provided with soil insertion rods 1 that transversely penetrate the counterweight block 7. 5. When the steel plate 4 and the counterweight 7 are fixed, the connecting rod 17 squeezes the mounting frame 12, so that the reset spring 16 is stretched, and the slide bar 11 slides downward on the slide rail 10, thereby making the inclined rod 13 squeeze the slide plate 14, so that the soil-inserting rods 15 on both sides move to the side away from each other, so that they can be inserted into the soil laterally, making it difficult for the counterweight 7 to move upward from the pit, thereby further improving the stability of the steel support. When it is necessary to move the pile driver 1, loosen the wire rope 6, and then remove the nut 9, the steel support and the steel plate 4 can be moved upward, so that the reset spring 16 drives the mounting frame 12 to reset upward, and the soil-inserting rod 15 can be retracted into the counterweight 7.

[0050] The abutment assembly includes an air bag 18 disposed on the outer wall of the counterweight block 7, and the air bag 18 is higher than the soil-inserting rod 15 to avoid puncture.

[0051] The inner walls of both sides of the counterweight block 7 are provided with connecting grooves 20, and the connecting grooves 20 on both sides are connected with connecting pipes 19 connected with the airbag 18. The inner walls of the connecting grooves 20 on both sides are fitted with movable plates 22, and the movable plates 22 on both sides are provided with connecting frames 21. The connecting frames 21 on both sides are respectively connected to the sliding rods 11 on both sides, and the connecting grooves 20 are located above the slide rails 10. Figure 5As shown, since it is difficult to accurately dig the pit to a size that is in close contact with the counterweight 7, it is difficult for the pit to be in close contact with the outer wall of the counterweight 7. Therefore, an airbag 18 is set on the outer wall of the counterweight 7. When the mounting frame 12 moves downward, the slide rod 11 drives the connecting frame 21 to move downward, so that the movable plate 22 can squeeze the air in the connecting groove 20, and then inflate the airbag 18 through the connecting pipe 19, so that the airbag 18 expands and fills the gap between the counterweight 7 and the pit, increasing the contact area with the pit and increasing the friction. After removing the steel plate 4, the movable plate 22 can be moved upward to extract the gas in the airbag 18, so that the airbag 18 is deflated, which does not affect the removal of the counterweight 7.

[0052] Both sides of the counterweight block 7 are connected with lifting components, and moving components are arranged on the lifting components.

[0053] The lifting assembly includes a fixed frame 23, a through slot 1 24 is vertically opened on the side of the fixed frame 23 away from the counterweight block 7, a through slot 25 is vertically opened on the side of the fixed frame 23 close to the counterweight block 7, a fixed rod 26 is slidably connected to the through slot 25, the fixed rod 26 is connected to the counterweight block 7, the fixed rod 26 is screwed to the screw rod 1 27, and a rotating shaft 1 28 connected to the fixed frame 23 through bearings is arranged on both the top and bottom sides of the screw rod 1 27, the rotating shaft 1 28 drives the screw rod 1 27 to rotate, so that the fixed rod 26 is raised and lowered, and the counterweight block 7 is raised and lowered.

[0054] The moving assembly includes a screw rod 29, a rotating shaft 2 30 is provided on both the top and bottom sides of the screw rod 29, and the rotating shaft 2 30 is connected to the fixed frame 23 through bearings, a wheel frame 31 is screwed on the screw rod 29, and universal wheels 32 are provided on the front and rear sides of the bottom of the wheel frame 31, gears 34 are provided on the rotating shaft 1 28 and the rotating shaft 2 30, and the gears 34 on both sides are meshed with each other, and a motor 33 is provided on the fixed frame 23, and the output shaft of the motor 33 is connected to the rotating shaft 2 30. The motor 33 drives the rotating shaft 2 30 to rotate, so that the gear 34 rotates with it, thereby driving the rotating shaft 1 28 and the rotating shaft 2 30 to rotate in the opposite direction, so that the moving directions of the fixed rod 26 and the wheel frame 31 are opposite.

[0055] A support rod 36 is disposed between the fixing frames 23 on both sides, and a handle 35 is disposed on one of the fixing frames 23 , so that the fixing frames 23 on both sides are connected together and can be pushed by the handle 35 .

[0056] When it is necessary to take out the counterweight 7, since the counterweight 7 is heavy, it is necessarily laborious to carry and take it out. Therefore, when the counterweight 7 is used, the fixed frame 23 contacts the ground outside the pit, and then the motor 33 works to make the wheel frame 31 drive the universal wheel 32 to move downward, so that the fixed rod 26 drives the counterweight 7 to move upward, and the pit can be moved out. At this time, the universal wheel 32 can contact the ground to lift the fixed frame 23, so that the fixed frames 23 on both sides and the counterweight 7 in the middle can be moved on the ground by the universal wheel 32 to the next location of the pile driver 1 for reinforcement, thereby reducing labor intensity.

[0057] The rest of the structure is the same as that of the first embodiment.

[0058] A method for preventing a high-pressure rotary jet pile machine from tipping over an anti-tipping bracket, using a high-pressure rotary jet pile machine from the second embodiment, specifically comprising the following steps:

[0059] Step 1: The steel plate 4 is embedded in advance to fix the steel support, and then the steel support is tightly connected to the pile driver 1 through the steel wire rope 6. When the pile driver 1 tilts, the steel support can stabilize the pile driver 1 to prevent the pile driver 1 from overturning, thereby ensuring construction safety;

[0060] Step 2: When encountering severe weather with strong winds, a soil pit matching the outer diameter of the counterweight block 7 is pre-dug on the ground around the pile driver 1, and then the counterweight block 7 is inserted into the soil pit, and then the steel plate 4 at the bottom of the profile steel support is placed on the counterweight block 7, and the steel plate 4 and the counterweight block 7 can be fixed together by screws 8 and nuts 9, thereby increasing the counterweight of the profile steel support and the depth of insertion into the soil, so that when encountering strong winds, the stability of the profile steel support can be improved, thereby better stabilizing the pile driver 1;

[0061] Step three: When the steel plate 4 and the counterweight 7 are fixed, the connecting rod 17 squeezes the mounting frame 12, so that the reset spring 16 is stretched, and then the inclined rod 13 squeezes the slide plate 14, so that the soil insertion rods 15 on both sides move to the side away from each other, so that they can be inserted into the soil laterally, making it difficult for the counterweight 7 to move upward from the soil pit, thereby further improving the stability of the steel support and further stabilizing the pile driver 1. Since the soil pit is difficult to be in close contact with the outer wall of the counterweight 7, an air bag 18 is arranged on the outer wall of the counterweight 7. When the mounting frame 12 moves downward, the slide bar 11 drives the connecting frame 21 to move downward, so that the movable plate 22 squeezes the air in the connecting groove 20, and then the air bag 18 is inflated through the connecting pipe 19, so that the air bag 18 expands and fills the gap between the counterweight 7 and the soil pit, increasing the contact area with the soil pit, increasing the friction force, thereby further improving the stability of the steel support;

[0062] Step 4: After the counterweight 7 is inserted into the earth pit, the bottom of the fixed frame 23 is supported by the ground. When the pile driver 1 needs to be moved, the wire rope 6 is loosened, and then the nut 9 is removed, and the steel support and the steel plate 4 can be moved upward, so that the reset spring 16 drives the mounting frame 12 to reset upward, so that the air bag 18 can be deflated, and the soil insertion rod 15 is retracted into the counterweight 7, and then the fixing rod 26 is driven upward by the lifting assembly, so that the counterweight 7 can be moved upward out of the earth pit. When the counterweight 7 moves upward, the wheel frame 31 drives the universal wheel 32 to move downward, so that when the counterweight 7 moves out of the earth pit, the universal wheel 32 can contact the ground to lift the fixed frame 23, so that it is convenient to move the fixed frames 23 on both sides and the middle counterweight 7 to the next location of the pile driver 1 for reinforcement through the handle 35 and the support rod 36.

[0063] That is, the present invention can effectively prevent the bracket from tipping over, thereby greatly improving the safety factor.

[0064] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any form of modification may be made within the scope of protection of the present invention.

The steel plate (4) at the bottom of the profile steel support is then placed on the counterweight (7), and the steel plate (4) and the counterweight (7) are fixed together by means of screws (8) and nuts (9), thereby increasing the counterweight of the profile steel support and the depth of insertion into the soil, thereby increasing the stability of the profile steel support when encountering strong winds, and thus better stabilizing the pile driver (1); Step 3: When the steel plate (4) and the counterweight (7) are fixed, the connecting rod (17) squeezes the mounting frame (12), so that the reset spring (16) is stretched, and then the inclined rod (13) squeezes the slide plate (14), so that the soil insertion rods (15) on both sides move to the side away from each other, so that they can be inserted into the soil horizontally, making it difficult for the counterweight (7) to move upward from the soil pit, thereby further improving the stability of the steel support and further stabilizing the pile driver (1). Since the soil pit is difficult to contact with the counterweight (7), The outer wall of the counterweight (7) is in close contact with the outer wall thereof, so an air bag (18) is arranged on the outer wall of the counterweight (7). When the mounting frame (12) moves downward, the slide bar (11) drives the connecting frame (21) to move downward, so that the movable plate (22) squeezes the air in the connecting groove (20), and then inflates the air bag (18) through the connecting pipe (19), so that the air bag (18) expands and fills the gap between the counterweight (7) and the earth pit, thereby increasing the contact area between the counterweight and the earth pit, increasing the friction force, and further improving the stability of the steel support; Step 4: After the counterweight (7) is inserted into the earth pit, the bottom of the fixed frame (23) is supported by the ground. When the pile driver (1) needs to be moved, the steel wire rope (6) is loosened, and then the nut (9) is removed, and the steel support and the steel plate (4) can be moved upward, so that the reset spring (16) drives the mounting frame (12) to reset upward, so that the air bag (18) is deflated, and the soil insertion rod (15) is retracted into the counterweight (7), and then the fixing rod (26) is driven by the lifting assembly. By moving upward, the counterweight (7) can be moved upward out of the earth pit. When the counterweight (7) moves upward, the wheel frame (31) drives the universal wheel (32) to move downward, so that when the counterweight (7) moves out of the earth pit, the universal wheel (32) can contact the ground to lift the fixed frame (23), so that the fixed frames (23) on both sides and the middle counterweight (7) can be moved to the next location of the pile driver (1) for reinforcement through the handle (35) and the support rod (36).
