Description

Technical Field

[0001] This invention belongs to the field of grouting machine technology, and in particular relates to a high-frequency grouting machine for oscillating grouting of environmentally friendly casing piles with a stable structure. Background Technology

[0002] Environmentally friendly casing piles are a new type of pile foundation engineering material, characterized by fast construction speed, high bearing capacity, strong adaptability, and environmental protection. Because environmentally friendly casing piles have an approximately 10mm annular gap on their sides, vibratory grouting machines are typically used during construction to grout the pile sides, thereby improving the bearing capacity of the environmentally friendly casing piles and reinforcing the pile foundation. Furthermore, if borehole collapse occurs during construction, grouting also helps to correct the resulting voids. Using vibratory grouting machines for pile side grouting is a novel grouting technology. During grouting, pressure pulses and fluid switching are generated, allowing the grout to spread more evenly in the soil around the pile, significantly improving the pile's bearing capacity.

[0003] However, this technology also has some problems: ① During grouting, the motor of the existing grouting machine will vibrate, causing the entire grouting machine to shake. This can lead to slippage during operation, affecting the use of the grouting machine and potentially impacting the smoothness of grout discharge; ② The grouting machine is used for drilling and grouting of environmentally friendly casing piles. The length of the grouting is long, there are many different strata, and the grout easily spreads along highly permeable strata and easily oozes upwards along the gap between the pile and the soil. However, the grouting pipe used in the existing grouting machine is a straight pipe, which leads to uneven grout flow and only one direction of velocity. The grout is prone to blockage in the forward direction, which has certain defects. Therefore, we propose a high-frequency grouting machine with a stable structure for environmentally friendly casing pile side oscillation grouting. Summary of the Invention

[0004] To address the problems existing in the prior art, the purpose of this invention is to provide a high-frequency grouting machine for environmentally friendly casing pile side vibration grouting with a stable structure.

Detailed Implementation

[0035] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0036] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0037] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0038] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0039] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0040] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0041] like Figures 1 to 10 As shown in the figure, the present invention provides a high-frequency grouting machine for side vibration grouting of environmentally friendly casing piles with a stable structure, comprising: a machine body 1, a base plate 2 provided on the lower surface of the machine body 1, rollers 4 provided at the four corners of the lower surface of the base plate 2, a grouting pipe 3 provided at one end of the machine body 1, and a nozzle 5 provided at one end of the grouting pipe 3; a limiting component 7, the limiting component 7 including a support rod 701 and a fixing component, the support rod 701 being provided on the lower surface of the base plate 2, the rollers 4 being rotatably installed at one end of the support rod 701, and the fixing component being slidably installed on the support rod 701, the fixing component and the rollers 4 being arranged vertically in correspondence;

[0042] Specifically, such as Figures 1 to 7 As shown, during use, the rollers 4 located below the base plate 2 facilitate the movement of the machine body 1 to the desired location, thereby improving the flexibility and convenience of the grouting machine. After the movement is completed, the base plate 2 descends, causing the fixing component to slide within the support rod 701. The lower end of the fixing component then contacts the rollers 4, automatically limiting the rollers 4 and preventing them from rotating. This completes the limiting function, thus preventing the entire grouting machine from moving. By using the weight above the base plate 2 and the fixing component to limit the rollers 4, the machine maximizes the limitation of the rollers 4, effectively preventing the concrete grouting machine from shaking during operation, which would affect its normal use. This also effectively avoids the problem of uneven grout flow during grouting, improves the stability of grouting, and prevents wear on some parts, thereby extending the service life of the grouting machine.

[0043] Furthermore, the support component 6 is fixedly connected to the limiting component 7, and the upper end of the support component 6 is correspondingly positioned to the lower surface of the base plate 2.

[0044] Specifically, such as Figures 1 to 4As shown, the support assembly 6 uses the support rod 701 as a support point. In use, the operator drives the support assembly 6 to make the base plate 2 slide down. The base plate 2 drives the fixing component to slide down within the support rod 701, thereby limiting the roller 4. Conversely, when the support assembly 6 rises, the base plate 2 drives the fixing component to rise, and the fixing component releases the limitation on the roller 4. This facilitates the movement of the fixing component and improves ease of use. After rising, the support assembly 6 serves as a support point for the base plate 2, supporting the device above the base plate 2, playing a crucial role. It should be noted that the support assembly 6 can only drive the base plate 2 to move up and down, thus avoiding jamming and unstable support.

[0045] Furthermore, the fixing component includes a movable block 702, which is slidably mounted on the upper end of the support rod 701. The movable block 702 has a groove inside, and multiple sets of first springs 703 are provided on the inner wall of the groove. The upper end of the first spring 703 is fixedly mounted on the lower surface of the base plate 2.

[0046] Specifically, such as Figure 3 As shown, multiple sets of first springs 703 are provided at the connection between the movable block 702 and the base plate 2. When the movable block 702 slides down into the support rod 701, the multiple sets of first springs 703 can eliminate the vibration generated by the grouting machine motor on the base plate 2 during operation, thereby preventing the grouting machine from shaking and slipping, and further improving the stability during use.

[0047] Furthermore, a support rod 704 is fixedly installed on the lower surface of the movable block 702, and a card seat 705 is provided at the lower end of the support rod 704. The card seat 705 includes a fixed seat 7051. Clamping blocks 7052 are rotatably installed at both ends of the lower surface of the fixed seat 7051. A protrusion 7054 is fixedly installed on the inner side of the clamping block 7052. The protrusion 7054 is correspondingly arranged with the outer side of the roller 4.

[0048] Specifically, such as Figures 5 to 7 As shown, when the movable block 702 slides down, the support rod 704 slides along with it. At this time, the support rod 704 presses down on the fixed seat 7051, causing the two sets of clamping blocks 7052 to move to both sides of the roller 4, limiting the roller 4. Furthermore, the roller 4 is further limited and fixed by multiple sets of protrusions 7054 contacting the outer side of the roller 4, thereby preventing the roller 4 from slipping due to vibration during use and improving the stability of use.

[0049] Furthermore, the clamping block 7052 and the fixed seat 7051 are rotatably connected by a rotating shaft 7055. A gear 7053 is provided at one end of the rotating shaft 7055. A notch is provided on one side of the inner wall of the support rod 701. A toothed plate 706 is provided on both sides of the notch. The gear 7053 is meshed with the toothed plate 706.

[0050] Specifically, such as Figure 6 and Figure 7 As shown, when the fixed base 7051 slides down, the gear 7053 slides along the teeth on the gear plate 706 to rotate, thereby causing the rotating shaft 7055 to drive one end of the two sets of clamping blocks 7052 to rotate below the fixed base 7051 to clamp the roller 4, thus achieving the effect of automatically limiting and fixing the roller 4 when the base plate 2 descends.

[0051] Furthermore, the support assembly 6 includes two sets of fixing plates 603, the fixing plates 603 are fixedly installed between the two sets of support rods 701, the support plate 8 is fixedly installed between the two sets of fixing plates 603, the connecting plate 604 is provided above the support plate 8, the lifting component 606 is provided between the connecting plate 604 and the support plate 8, and two sets of buffer components 9 are fixedly installed on the upper surface of the fixing plates 603.

[0052] Specifically, such as Figure 2 and Figure 3 As shown, the fixing plate 603 is fixed between two sets of support rods 701 that are far apart. The support rods 701 increase the support force of the fixing plate 603. Thus, when the support plate 8 is fixed between the two sets of fixing plates 603, it can provide support for the lifting component 606, so that the lifting component 606 can operate normally.

[0053] Furthermore, the connecting plate 604 is arranged in an X shape, and extension blocks 605 are fixedly installed on both sides of the intersection of the connecting plate 604. The upper end of the extension block 605 is set on the lower surface of the base plate 2. A support column 601 is fixedly installed on the lower surface of the extension block 605. The upper surface of the support plate 8 has slots at both ends, and the support column 601 is slidably installed in the slots. A gripping plate 602 is fixedly installed at the lower end of the support column 601.

[0054] Specifically, such as Figures 1 to 4 As shown, the X-shaped arrangement of the connecting plate 604 reduces the area occupied without diminishing the support effect, allowing other devices to better showcase their respective effects. The extension blocks 605 on both sides of the X-shaped connecting plate 604 can move along the movement trajectory of the base plate 2. Thus, when the base plate 2 rises, it will cooperate with the connecting plate 604 to support the base plate 2. When the base plate 2 falls, it will cause the support column 601 to fall, allowing the gripping plate 602 to contact the ground for support. At the same time, the lower surface of the gripping plate 602 can provide gripping force, which, together with the limiting component 7, supports and stabilizes the entire grouting machine.

[0055] Furthermore, the lifting component 606 includes an adjusting wheel 6061 and two sets of lead screws 6063. The upper surface of the support plate 8 has placement grooves on both sides. The lead screws 6063 are placed in the placement grooves. A folding rod 6065 is provided on the lead screws 6063. The adjusting wheel 6061 is provided at one end of the lead screws 6063. A rotating wheel 6064 is provided on the outer surface of one end of each set of lead screws 6063. A belt 6062 is provided between the two sets of rotating wheels 6064.

[0056] Specifically, such as Figure 3 and Figure 4 As shown, when the operator rotates the adjusting wheel 6061, it drives a set of lead screws 6063 to rotate. At this time, the belt 6062 causes two sets of rotating wheels 6064 to rotate simultaneously, thereby causing the two sets of lead screws 6063 to rotate simultaneously. This unfolds the folding rod 6065, causing the base plate 2 to rise. Conversely, rotating in the opposite direction causes the folding rod 6065 to retract, which in turn causes the base plate 2 to fall, thus achieving the effect of convenient use.

[0057] Furthermore, the buffer component 9 includes a mounting base 901, which is disposed on the fixed plate 603. Multiple sets of second springs 903 are disposed inside the mounting base 901. A movable plate 902 is disposed at one end of each second spring 903. The movable plate 902 is disposed vertically and vertically corresponding to the lower surface of the base plate 2.

[0058] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, after the base plate 2 is lowered, its lower surface will fit against the mounting base 901. Subsequently, during use, the mounting base 901 uses the second spring 903 to dampen the base plate 2. At the same time, in conjunction with the multiple sets of first springs 703 mentioned above, it eliminates the vibration generated by the grouting machine motor, further improving the stability of the grouting machine during use.

[0059] Furthermore, the nozzle 5 includes an outer cylinder 501, with an inlet 502 at the upper end of the outer cylinder 501, an outlet 503 at the lower end of the outer cylinder 501, and a cross-shaped rotating mixing channel 504 inside the outer cylinder 501.

[0060] Specifically, such as Figure 1 , Figure 9 and Figure 10 As shown, the inlet 502 is used to introduce grouting material. The grout generates a rotating acceleration motion through the cross-shaped rotating mixing channel 504 and is sprayed out in the direction of rotation. The outlet 503 is used to guide the sprayed grouting material into the target area.

[0061] Furthermore, the outer side of the cross-shaped rotary mixing channel 504 is a rotary channel 505, the middle part inside the cross-shaped rotary mixing channel 504 is a direct current channel 506, one end of the outer cylinder 501 is provided with an external thread, and one end of the grouting pipe 3 is provided with an internal thread that is threaded to the external thread.

[0062] The upper 15mm of the outer cylinder 501 is externally threaded, and it is connected to the grouting pipe 3 through the external thread, thus achieving the effect of convenient installation. Finally, the grouting pump provides pressurized grout, which is injected into the external building structure through the pump, the pipeline and the nozzle 5.

[0063] Specifically, such as Figure 1 , Figure 9 and Figure 10 As shown, the cross-shaped rotating mixing channel 504 is directly connected to the inner wall of the outer cylinder 501. The rotating channel 505 forms a rotating channel by its own twisting. The fluid passes through the rotating channel 505 and rotates at the edge of the rotating channel 505. It is repeatedly impacted and stirred evenly with the middle direct current channel 506. Under the pressure of the fluid behind, it changes from direct current to mixed vortex, which solves the problems of uneven grouting and poor grouting effect in the existing technology. At the outlet 503, the grout is evenly mixed and obtains velocity in three directions, which effectively solves the phenomenon of grout overflowing upward along the pile side and alleviates the phenomenon of particle blockage, greatly improving the grouting performance.

[0064] It is worth noting that the nozzle 5 injects grout in the form of a rotating jet through the cross-shaped rotating mixing channel 504. By utilizing the characteristics of the rotating jet, the uniformity of grouting is improved. Furthermore, the rotation direction of the nozzle 5 can be adjusted according to actual needs to adapt to the grouting requirements of different engineering projects. Compared with traditional grouting nozzles, the rotating jet nozzle 5 of this invention can better fill voids and loose areas, improve soil compaction, and enhance foundation stability.

[0065] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0066] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
