Description

Technical Field

[0001] This invention relates to the field of civil engineering technology, specifically to a grout preparation and injection device for delamination grouting. Background Technology

[0002] In a broad sense, delamination refers to the difference in settlement between different rock strata in a top slab due to asynchronous settlement. In a top slab composed of multiple rock strata, delamination can occur in multiple locations. Delamination mostly occurs between rock strata with significant lithological differences. Delamination grouting is a commonly used foundation reinforcement method. It involves injecting grout into the foundation to form a solid grout layer, thereby improving the foundation's bearing capacity and stability. The principle of delamination grouting is to utilize the viscosity and adhesion of the grout to fill loose soil layers and voids in the foundation, forming a solid grout layer, thus increasing the foundation's bearing capacity and stability.

[0003] Existing equipment often only allows the prepared slurry to be injected into the delamination. However, the properties of the slurry will change to some extent during the transportation process, and this method will increase the loss of slurry and increase the time for delamination grouting. When grouting into the existing delamination, the grouting hole is not necessarily a vertical hole, and its depth is also uncertain. At the same time, during the grouting process, the height of the grouting port should rise as the slurry is injected. Existing equipment cannot take multiple aspects into account at the same time, which greatly reduces the efficiency of delamination grouting.

[0004] Therefore, it is necessary to provide a grout preparation and injection device for delamination grouting to solve the above problems. Summary of the Invention

[0028] Compared with the prior art, the present invention provides a grout preparation and injection device for delamination grouting, which has the following beneficial effects:

[0029] 1. In this invention, multiple sets of device components work together to simultaneously prepare and inject slurry, simplifying the slurry injection process and improving its injection efficiency. The fluid injection component, solid injection component, and raw material mixing tank are all equipped with weight monitoring components to monitor the overall weight in real time, preventing residues from affecting the proportion of subsequent slurry raw materials, improving the accuracy of the device, and utilizing the residues to save resources, eliminate cleaning time, and improve the efficiency of preparation and slurry injection. Simultaneously, the volumes of the slurry storage tank and raw material mixing tank maintain a certain volume relationship, ensuring stable slurry volume in the slurry storage tank, maintaining slurry pressure and slurry rate to a certain extent. Furthermore, a raw material screening sieve is installed above the solid injection component, sending large particles in the raw materials to a solid pulverizer for crushing before injecting them into the solid mixing tank. This reduces the screening work of solid raw materials while ensuring the solid volume, reducing preparation time to a certain extent, and the method does not affect the quantitative injection ratio of raw materials.

[0030] 2. In this invention, the grout injection device includes a grout injection component that can adjust the injection angle and a certain range of injection depth. With the assistance of the injection depth adjustment component, the range of injection depth can be adjusted to prevent the grout injection nozzle from being too high, causing splashing and affecting the adhesion of the delamination layer, thus ensuring the bearing capacity and stability of the foundation. Conversely, it prevents the grout injection nozzle from being too low, causing blockage. Additionally, three sets of fixing and clamping components assist the injection depth adjustment component in its operation, facilitating the process and improving grouting efficiency.

[0039] Please see Figures 1-7 This invention provides a grout preparation and injection device for delamination grouting, comprising:

[0040] The equipment frame 1 has a fluid injection component 2 fixedly mounted on its upper end and a solid injection component 3, a raw material mixing tank 4, a slurry storage tank 5, and a slurry injection device 7 fixedly mounted on its lower end. The fluid injection component 2, the raw material mixing tank 4, the slurry storage tank 5, and the slurry injection device 7 are connected through an output pipe. The solid injection component 3 is connected to the raw material mixing tank 4, and the raw material mixing tank 4 is connected to the slurry storage tank 5 through a screw conveyor component 6.

[0041] A stirring assembly 8 is fixedly installed on the fluid injection assembly 2, the solid injection assembly 3, the raw material mixing tank 4, and the slurry storage tank 5.

[0042] The fluid injection component 2 and the solid injection component 3 are provided with a telescopic connecting pipe 9 at the connection with the lower end;

[0043] In a preferred embodiment, the raw materials for slurry preparation are quantitatively conveyed to the fluid injection component 2 or the solid injection component 3 via an external conveying device. After initial mixing by the stirring component 8 within the component, the materials are conveyed to the raw material mixing tank 4 via an output pipe or a screw conveyor component 6. The stirring component 8 in the raw material mixing tank 4 further mixes the raw materials to prepare a slurry, which is then conveyed to the slurry storage tank 5 via another set of screw conveyor components 6. The slurry injection device 7 adjusts its injection angle and initial injection depth according to the specific situation of the injected delamination and the state of the injection hole, and then transfers the slurry from the slurry storage tank 5. The fluid is drawn out of tank 5 and injected into the separation layer. The fluid injection component 2, solid injection component 3, and raw material mixing tank 4 are all equipped with weight monitoring components to monitor their overall weight in real time. Let the initial mass be A, and the mass after one slurry preparation and injection process be B (a certain amount of raw material will adhere to the tank wall, and the adhered material is the residue of the mixed material). The absolute value of the difference between the two is the mass of the mixed raw material in the corresponding tank. Multiplying this mass by the mixing ratio yields the residual mass of each raw material in the tank. When the types of raw materials for the slurry injected into the separation layer before and after the equipment remain unchanged, the residual mass can be used to determine the mass of the raw material in the subsequent... The raw materials are replenished continuously to prevent residues from affecting the proportion of subsequent slurry raw materials, improve the accuracy of the device, and utilize the residues to save resources, eliminate cleaning time, and improve the efficiency of preparation and slurry injection. The mixing time in the raw material mixing tank 4 is denoted as t1, the time required to transfer the slurry from the raw material mixing tank 4 to the slurry storage tank 5 is denoted as t2, the stirring volume in the raw material mixing tank 4 is denoted as s1, the maximum volume of slurry in the slurry storage tank 5 is denoted as s, the volume of slurry in the slurry storage tank 5 is denoted as s2, and the slurry injection rate is denoted as v. Therefore, during the slurry injection process, s2 = s1 - vt1. This ensures the slurry volume in the slurry storage tank 5, maintains the grouting pressure to a certain extent, and maintains the grouting rate. In the selection of the slurry volume in the slurry storage tank 5, 10%s≤s2≤90%s is selected to ensure that the slurry inside has a certain pressure, while preventing the internal volume from being too large, so that the stirring scraper set in the slurry storage tank 5 can not effectively clean the attached slurry inside. The setting of the telescopic connecting pipe 9 separates the fluid injection component 2 and the solid injection component 3 from the corresponding output pipe or spiral conveying component 6 in terms of mass, preventing its own weight from affecting the measurement of the weight of the fluid injection component 2 and the solid injection component 3.

[0044] Furthermore, the solid injection component 3 includes:

[0045] Three sets of support columns 31 are vertically arranged and are fixedly assembled on the inner wall of the bottom of the equipment. A tank weighing component 32 is fixedly arranged between the support columns 31, and a solid mixing tank 33 is fixedly arranged at the upper end of the support columns 31. A raw material screening screen 34 is arranged at the upper end of the solid mixing tank 33.

[0046] A fixed bracket 35 is fixedly mounted on the upper end of the equipment frame 1, and a solid pulverizer 36 is fixedly mounted on it. A solid injection pipe 37 is provided on the lower output port of the solid pulverizer 36 and connected to the solid mixing tank 33.

[0047] In a preferred embodiment, the solid raw materials have certain requirements regarding particle size. Particles that are too large will affect the adhesion of the delamination layer and cannot effectively increase the bearing capacity and stability of the foundation. The raw material screening sieve 34 can identify the injected raw materials, placing the qualified particles into the solid mixing tank 33, while the unqualified particles fall into the solid pulverizer 36 under its shaking. The solid pulverizer 36 pulverizes the large particles and injects the pulverized solid particles into the solid mixing tank 33 through the solid injection pipe 37 for mixing. During the preparation process, the screening of solid raw materials is reduced while ensuring the solid volume, which reduces the preparation time to a certain extent. Moreover, this method does not affect the proportion of the quantitatively injected raw materials. The shrinkage tank weighing component 32 can monitor the quality of the solid mixing tank 33 and provide feedback, which facilitates the subsequent work.

[0048] Furthermore, the tank weighing assembly 32 includes:

[0049] Two sets of bearing blocks 321 are mirror-arranged and fixedly assembled between the support columns 31. A weighing component 322 is fixedly assembled between the two sets of bearing blocks 321.

[0050] A first hydraulic cylinder 323 is fixedly mounted on the lower bearing block 321, and a tank fixing block 324 is horizontally fixedly mounted on the other end of the first hydraulic cylinder 323.

[0051] In a preferred embodiment, during the raw material mixing and preparation process, the first hydraulic cylinder 323 extends, causing the three sets of tank fixing blocks 324 to clamp the solid mixing tank 33, preventing the weighing component 322 from maintaining a weighing state at all times, reducing its pressure, and increasing its service life. When weighing is required, the first hydraulic cylinder 323 retracts, and the weight of the solid mixing tank 33 is borne by the three sets of weighing components 322, which facilitates the measurement of the weight of the solid mixing tank 33 and the adhering substances on its tank wall, and facilitates the subsequent work.

[0052] Furthermore, the support frame of the fluid injection component 2 is also equipped with a tank weighing component 32, which facilitates subsequent work.

[0053] Furthermore, the slurry injection device 7 includes:

[0054] A fixed plate 71 is fixedly mounted on the inner wall at the bottom of the equipment frame 1. A pressurizing component 72 is fixedly mounted on its front side. The pressurizing component 72 is equipped with a switch valve 74 and a pressure gauge 75. The left and right ends are respectively connected to a slurry injection component 76 and a slurry storage tank 5 through a slurry flow pipe 73. The slurry injection component 76 is fixedly mounted with an injection depth adjustment component 77 and three sets of fixed clamping components 78.

[0055] In a preferred embodiment, the slurry injection component 76 can adjust the injection angle and a certain range of injection depth. With the assistance of the injection depth adjustment component 77, the range of injection depth of the slurry injection component 76 can be adjusted. The three sets of fixing and clamping components 78 assist the operation of the injection depth adjustment component 77. The pressurizing component 72 increases the injection pressure of the slurry and stabilizes it at a certain pressure value.

[0056] Furthermore, the slurry injection assembly 76 includes:

[0057] A rotating disk 761 has a drive motor embedded in a fixed plate 71 on its back side, and a sliding rail 762 is fixedly mounted on it. A slurry injection pipe 763 and a sliding drive assembly 764 are slidably mounted on the sliding rail 762. The sliding drive assembly 764 is fixedly mounted above the slurry injection pipe 763. A slurry flow pipe 73 is connected to the right side of the slurry injection pipe 763. A rotating connecting sleeve 765 is rotatably mounted at the lower end of the slurry injection pipe 763. n sets of connecting pipes 766 are coaxially mounted at the lower end of the rotating connecting sleeve 765, and a slurry injection nozzle 767 is coaxially mounted at the lower end of the lowest connecting pipe 766.

[0058] In a preferred embodiment, the drive motor on the back of the drive disc 761 can rotate the slurry injection component 76, thereby changing the angle between the slurry injection pipe 763 and the ground, and thus changing the injection angle of the slurry. At the same time, the sliding track 762 allows the slurry injection pipe 763 to move up and down under the action of the sliding drive component 764, so as to change the relative height of the slurry injection nozzle 767 within a certain range, that is, to change the injection depth of the slurry. The number n of the extension pipes 766 is a positive integer and greater than or equal to 1. The device should select the maximum number of extension pipes 766 according to the depth of the delamination, so that the slurry injection nozzle 767 can start injecting from the bottom of the delamination, preventing it from splashing too high and affecting the adhesion of the delamination, thereby ensuring the bearing capacity and stability of the foundation.

[0059] Furthermore, the upper and lower ends of the connecting pipe 766 and the upper end of the slurry injection nozzle 767 are all provided with external threads, and the lower end of the connecting pipe 766 is coaxially threaded with a connecting sleeve 768.

[0060] In a preferred embodiment, the connecting sleeve 768 and the threaded design allow the extension pipe 766 to be connected to the slurry injection pipe 763, thereby adjusting the relative height of the slurry injection nozzle 767 and ensuring the slurry injection effect.

[0061] Furthermore, the injection depth adjustment component 77 includes:

[0062] A fixed frame 771 is fixedly mounted on a rotating disk 761, and a second hydraulic cylinder 772 is fixedly installed on its right side. A clamping and fixing component 773 is fixedly installed on the right side of the second hydraulic cylinder 772.

[0063] The continuation pipe storage box 774 is fixedly mounted on the rotating disk 761. A spring 775 is provided on its left inner wall. A push plate 776 is provided on the right side of the spring 775. Multiple sets of continuation pipes 766 are placed on the right side of the push plate 776.

[0064] The descending buffer block 778 is fixedly mounted on the rotating disk 761;

[0065] In a preferred embodiment, the slurry injection is from bottom to top. After the sliding drive assembly 764 drives the slurry injection pipe 763 to rise to a certain height, the second hydraulic cylinder 772 extends, causing the clamping and fixing member 773 to clamp onto the corresponding extension pipe 766. The three sets of fixing and clamping assemblies 78 clamp the corresponding positions, and by rotating the clamping position, the extension pipe 766 is unloaded. The second hydraulic cylinder 772 retracts, and the extension pipe is placed into the extension pipe storage box 774 by an external robotic arm. At the same time, the sliding drive assembly 764 drives the slurry injection pipe 763 to descend and connect to the lower end under the action of the corresponding fixing and clamping assembly 78, facilitating subsequent slurry injection work.

[0066] Furthermore, an anti-fall plate 777 is fixedly provided on the upper end of the clamping and fixing member 773, and the anti-fall plate 777 is slidably disposed at the bottom of the extension pipe storage box 774;

[0067] In a preferred embodiment, when the splicing of the extension pipe 766 is performed in the initial state, the second hydraulic cylinder 772 extends, causing the splicing pipe 766, held by the clamping and fixing member 773, to reach a position coaxial with the slurry injection pipe 763. The connection is completed under the action of the corresponding fixing and clamping assembly 78. During this process, the anti-fall plate 777 blocks the drop hole of the splicing pipe storage box 774 to prevent it from falling. After a set of splicing pipes 766 is spliced, the second hydraulic cylinder 772 retracts. Under the action of the spring 775 and the push plate 776, the splicing pipe 766 is pushed to the far right and falls through the lower hole. It is then buffered by the descending buffer block 778 and falls between the clamping and fixing members 773. The previous operation is repeated until the splicing pipe 766 is replenished.

[0068] Furthermore, the fixing clamping assembly 78 includes:

[0069] A clamping block 781 is fixedly mounted on a rotating disk 761. A first drive motor 782 is fixedly mounted on its lower end. A fixed connecting rod is fixedly mounted on the output shaft of the first drive motor 782. Two sets of drive connecting rods 783 are rotatably mounted on the other end of the fixed connecting rod. Clamping connecting rods 784 are rotatably mounted on the other end of the drive connecting rods 783. The clamping connecting rods 784 are rotatably mounted on the clamping block 781. A clamping ring 785 is rotatably mounted on the inner side of the clamping connecting rod 784. The two sets of clamping rings 785 are rotatably connected on the right side. The lower end of the rings 785 is provided with teeth and meshes with a drive gear 786. A second drive motor 787 is provided on the right side of the drive gear 786. The second drive motor 787 is fixedly mounted on the lower end of the clamping block 781.

[0070] In a preferred embodiment, the left middle of the clamping and fixing block 781 is provided with an adsorption telescopic rod, which is adsorbed onto the rotating shaft between the two sets of clamping and fixing blocks 781, keeping it on the central axis of the adsorption telescopic rod. When the second drive motor 787 is started, it stops adsorption, thereby ensuring the rotation of the two sets of clamping rings 785, and continues adsorption after the second motor 787 is driven. The inner radius of the clamping ring 785 is smaller than the inner radius of the clamping connecting rod 784. In the initial state, the fixing and clamping assembly 78 is in an open state. After it is clamped by the action of the first drive motor 782, the clamping ring 785 meshes with the drive gear 786 and rotates under the action of the second drive motor 787, driving the corresponding rotating connecting sleeve 765 or connecting sleeve 768 to rotate, so that the extension pipe 766 is disengaged from or inserted into the slurry injection pipe 763.

[0071] In specific implementation, the following steps are included: the raw materials for slurry preparation are quantitatively conveyed to the fluid injection component 2 or the solid injection component 3 by an external conveying device, and after preliminary mixing by the stirring component 8 inside, they are conveyed to the raw material mixing tank 4 through the output pipe or the screw conveying component 6. The stirring component 8 inside the raw material mixing tank 4 further mixes the raw materials to prepare a slurry, and then conveys it to the slurry storage tank 5 through another set of screw conveying components 6. The slurry injection device 7 adjusts its injection angle and initial injection depth according to the specific situation of the injected delamination and the state of the injection hole, and sucks the slurry out of the slurry storage tank 5 and injects it into the delamination.

[0072] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
