Description

Technical Field

[0001] This utility model relates to the field of in-situ solidification construction, and in particular to an in-situ solidification construction device based on deep silt soft foundation. Background Technology In the field of foundation treatment, in-situ solidification equipment for deep silt soft soil foundations is being used more and more widely. This equipment works by bringing solidifying agents (such as cement, lime, fly ash, and industrial waste) into full contact with the soil particles. Through a series of physicochemical reactions, the soft soil with low bearing capacity is rapidly formed into a hard shell layer with a certain strength in situ, thereby meeting the foundation strength requirements of the project.

[0002] The curing construction equipment mainly consists of a conveying device, a mixing device, and a control device. First, the conveying device is responsible for transporting the curing material from the raw material silo to the mixing device, which then mixes the material. Finally, the control device monitors and adjusts the entire system to ensure that all parts of the equipment work together to achieve a stable and efficient construction process.

[0003] In existing technologies, some curing construction equipment and devices typically use replacement filling for curing, which cannot guarantee that the slurry can be uniformly mixed and penetrated to the specified depth in situ. This makes it unsuitable for the construction needs under the complex geological conditions of intertidal mudflats, thus reducing the curing efficiency. To address this issue, a new in-situ curing construction equipment based on deep silt soft foundation is proposed. Utility Model Content

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 8 This application will be described in further detail below.

[0032] Example: An in-situ solidification construction device based on deep silt soft foundation, referring to... Figure 1 , Figure 2 and Figure 4 The system includes a support base plate 1, which ensures the stability of the equipment during construction. Two admixture preparation mechanisms 2 are installed on the top of the support base plate 1. Each admixture preparation mechanism 2 includes two support frames 21, which ensure the small mixing tank a24 is stably positioned in a designated location, preventing displacement and tipping due to vibration during mixing, thus ensuring the smooth progress of the admixture preparation process. The bottoms of the two support frames 21 are fixedly connected to the top of the support base plate 1, and the small mixing tank a24 is fixedly connected to the top of the support frames 21. The small mixing tank a24 is used for separately containing and initially mixing different admixture solutions. Multiple partition plates 25 are fixedly connected inside the small mixing tank a24, dividing the interior of the small mixing tank a24 into multiple independent areas. A support column 23 is fixedly connected to the bottom of the small mixing tank a24, connecting the small mixing tank a24 and the extraction component 26, serving as a support and conveying transition. The output end of the support column 23 is fixedly connected to the extraction component 26. Specifically, during construction, the admixture raw materials are placed into the small mixing tank a24 and divided into different areas by the partition plate 25 to complete the initial mixing. Then, the admixture solution enters the extraction component 26 through the support column 23. The extraction component 26 extracts the solution. The support frame 21 of the two admixture preparation mechanisms 2 stably supports the small mixing tank a24. The whole process is carried out under the support of the support base plate 1. The various structures work together to complete the admixture preparation process, providing the required admixture for the subsequent in-situ solidification of the deep silt soft foundation.

[0033] The extraction assembly 26 includes two extraction pumps 2601, which provide power to extract the solution from one container and transport it to another. The inlet of one extraction pump 2601 is fixedly connected to the output of the support column 23, and the output of the other extraction pump 2601 is fixedly connected to an inlet pipe a2602. The inlet pipe a2602 transports the external admixture solution extracted by the extraction pump 2601 to the interior of the large mixing tank b32. The output of the inlet pipe a2602 is fixedly connected to the inside of the top side of the large mixing tank b32. Multiple support columns 23 are fixedly connected to the bottom of the small mixing tank a24. A support frame 22 is fixedly connected inside the support frame 21. A mixing mechanism 3 is provided on the top of the support base 1. The mixing mechanism 3 includes a support seat 31, which supports the large mixing tank b32 and the large mixing tank c35, providing a mounting base for them. The bottom of the support seat 31 is fixedly connected to the top of the support base 1. A large mixing tank b32 is fixedly connected to the top of the support base 31. The large mixing tank b32 performs preliminary mixing of multi-component materials. A large mixing tank c35 is fixedly connected to the bottom of the inner side of the support base 31. Two fixing sleeves 33 are fixedly connected to the top of the large mixing tank b32. The fixing sleeves 33 fix the input pipe 38 to ensure the stability of the connection between the input pipe 38 and the large mixing tank b32. The input pipe 38 is fixedly connected to the right side of the fixing sleeves 33. A support plate 34 is fixedly connected to the top of the support base 31. The support plate 34 provides auxiliary support for the large mixing tank b32 and other components, enhancing the stability of the top structure of the support base 31. A water inlet 36 is fixedly connected to the top of the large mixing tank c35. The large mixing tank c35 can dynamically adjust the dilution ratio according to the actual moisture content of the sludge on site, so that the mixture is more compatible with the sludge. Water is injected into the large mixing tank c35 through the water inlet 36 to dilute the pre-mixed materials. Specifically, during operation, the support column 23 at the bottom of the small mixing tank a24 provides stability, the support frame 22 inside the support frame 21 provides support, the extraction pump 2601 of the extraction component 26 is started, and the external admixture solution is transported to the large mixing tank b32 through the inlet pipe a2602. At the same time, the input pipe 38 feeds the material into the large mixing tank b32 through the fixing sleeve 33. The large mixing tank b32 performs preliminary mixing of the multi-component materials. The support plate 34 on the support base 31 provides auxiliary support. The pre-mixed material enters the large mixing tank c35, and the water inlet 36 injects water into the large mixing tank c35. The large mixing tank c35 adjusts the dilution ratio according to the moisture content of the sludge to complete the preparation of the mixed solution.

[0034] A power assembly 37 is fixedly connected to the bottom of the large mixing tank b32. The power assembly 37 controls the conveying of the initially mixed material in the large mixing tank b32 to the large mixing tank c35, as well as the output of the material in the large mixing tank c35. The power assembly 37 includes a control valve a3701, which controls the opening and closing of the output pipe 3702 and regulates the material flow rate through the output pipe 3702. The inlet end of the control valve a3701 is fixedly connected to the inner bottom of the large mixing tank b32, and the output end of the control valve a3701 is fixedly connected to the inside of the large mixing tank c35. The output pipe 3702 is fixedly connected to the outside of the control valve a3701. The output pipe 3702 conveys the initially mixed material in the large mixing tank b32 to the inside of the large mixing tank c35. An input pipe 38 is fixedly connected to the right side of the inside of the large mixing tank c35. The input pipe 38 serves as one of the material conveying channels, working with other components to complete the transfer of materials between different devices and ensuring the integrity of the entire material conveying system. For smooth operation, the output end of the input pipe 38 is fixedly connected to a mortar pump 3703. The mortar pump 3703 provides power for the material diluted in the large mixing tank c35 to be transported through the inlet pipe 3704. The output end of the mortar pump 3703 is fixedly connected to the inlet pipe 3704, which realizes the transportation of material from the large mixing tank c35 to the subsequent construction equipment, providing material guarantee for the sludge solidification treatment of equipment such as the tracked excavator 6. The outside of the inlet pipe 3704 is fixedly connected to a control valve b3705, which controls the on / off of the material transportation and the flow rate in the inlet pipe 3704. The top of the support base plate 1 is fixedly connected to the tracked excavator 6. The tracked excavator 6 flexibly adjusts the working depth and mixing intensity of the mixing head 41 according to the irregularity of the sludge depth, and cooperates with the slurry transportation system for construction. One of the external admixture configuration mechanisms 2 is equipped with a diluent mixing mechanism 5 on its top. The diluent mixing mechanism 5 mixes the diluent to ensure the uniformity of the diluent. Specifically, the material initially mixed in the large mixing tank b32 is conveyed under the action of the power component 37. The control valve a3701 is opened, and after the flow rate is adjusted, the material enters the large mixing tank c35 through the output pipe 3702. At the same time, the input pipe 38 can convey other materials to the large mixing tank c35. The diluent mixing mechanism 5 at the top of the external admixture preparation mechanism 2 mixes the diluent and sends it into the large mixing tank c35. The diluted material in the large mixing tank c35 is powered by the mortar pump 3703 and conveyed through the inlet pipe 3704. The control valve b3705 controls its on / off state and flow rate. The material is finally conveyed to the tracked excavator 6 and other subsequent construction equipment. The tracked excavator 6 adjusts the working depth and intensity of the mixing head 41 according to the silt depth to cooperate in the silt solidification treatment.

[0035] Reference Figure 3 and Figure 8 The diluent mixing mechanism 5 includes a sealed processing box 51, which ensures the safety and cleanliness of the diluent mixing process, avoids waste of diluent and the mixing of external impurities, and ensures the purity and quality of the diluent. The bottom of the sealed processing box 51 is fixedly connected to the top of the support frame 21. The output end of another extraction pump 2601 is fixedly connected to the feed pipe b52, which provides a solution delivery channel for the diluent mixing mechanism 5, ensuring the supply of materials required for diluent mixing and ensuring the normal operation of the diluent mixing mechanism 5. The tracked excavator 6 is equipped with a quick-change mechanism 4 on the outside. The output end of the inlet pipe 3704 is fixedly connected to the inside of the left side of the tracked excavator 6. The support base 31 is fixedly connected to the outside of the slurry conveying frequency controller 8. The right side of the tracked excavator 6 is fixedly connected to the outside of the curing agent outlet 7. Specifically, the sealed processing box 51 of the diluent mixing mechanism 5 starts to operate. At this time, another extraction pump 2601 delivers the required solution to the sealed processing box 51 through the inlet pipe b52. The diluent is mixed in the sealed processing box 51. Meanwhile, the quick change mechanism 4 on the outside of the tracked excavator 6 is in standby mode, ready to replace the corresponding parts according to the operation requirements. The inlet pipe 3704 delivers the relevant materials to the left side of the tracked excavator 6 to provide the necessary material support for the operation of the tracked excavator 6. The slurry frequency controller 8 on the outside of the support base 31 monitors and adjusts the slurry frequency of the entire device in real time to ensure that the slurry process is stable and orderly. After the tracked excavator 6 completes the corresponding operation steps, the curing agent is discharged through the curing agent outlet 7 on its right side to participate in the subsequent operation.

[0036] Reference Figures 5 to 7The quick-change mechanism 4 includes a protective support shell 42, which connects the tracked excavator 6 and the mixing head 41, enabling the mixing head 41 to operate under the drive of the tracked excavator 6. It also protects internal components from external environmental influences, extending their service life. The top of the protective support shell 42 is fixedly connected to the bottom of the tracked excavator 6, and the mixing head 41 is rotatably connected to the bottom of the protective support shell 42. The mixing head 41 mixes the sludge and the mixture, ensuring thorough mixing and solidification of the sludge. Multiple limiting grooves 46 are provided inside the mixing head 41, providing sliding tracks for limiting blocks 47, thus limiting the movement trajectory of the limiting blocks 47 and constraining the movement direction of the supporting sliding block 410. Limiting blocks 47 are slidably connected inside the limiting grooves 46, connecting the limiting grooves 46 and the supporting sliding block 410. The moving block 410 transmits the constraint of the movement trajectory of the limiting groove 46 to the supporting sliding block 410, and at the same time enhances the connection stability between the supporting sliding block 410 and the internal structure of the stirring head 41. The supporting sliding block 410 is fixedly connected to the side of the limiting block 47. The supporting sliding block 410 plays a supporting and sliding adjustment role inside the stirring head 41, participates in the structural adjustment of the stirring head 41 and the realization of the auxiliary stirring function. The bottom of the protective support shell 42 is fixedly connected to the drive assembly 411. The drive assembly 411 provides power output for the rotation of the stirring head 41 and the movement of the follower plate 48, and is the power source of the entire quick change mechanism 4. The drive assembly 411 includes a motor 41101. The motor 41101 is the core power device of the drive assembly 411 and provides rotational power. The motor 41101 is externally fixedly connected inside the protective support shell 42. Specifically, when the quick-change mechanism 4 starts operating, the motor 41101 in the drive assembly 411 is first started, outputting rotational power. This power drives the stirring head 41 to start rotating. As the stirring head 41 rotates, it directly acts on the sludge and the mixture, stirring them together. During the rotation of the stirring head 41, the supporting sliding block 410 moves inside the stirring head 41. Since the limiting block 47 is fixedly connected to the side of the supporting sliding block 410 and slidably connected inside the limiting groove 46, the movement direction of the supporting sliding block 410 is constrained by the limiting groove 46. The limiting block 47 slides along the track of the limiting groove 46, thus moving the supporting sliding block 410 along the defined trajectory. During this process, the drive assembly 411 continuously provides power to ensure that the rotation of the stirring head 41 and the movement of the supporting sliding block 410 and the limiting block 47 can continue until the sludge and the mixture are fully mixed under the action of the stirring head 41, completing the sludge solidification operation.

[0037] The drive end of the drive assembly 411 is fixedly connected to a support connecting shell 41102. The support connecting shell 41102 connects the drive end of the motor 41101 to the cylinder 41103, providing a mounting and fixing structure for the cylinder 41103 and transmitting the rotational power of the motor 41101. The cylinder 41103 is fixedly connected inside the support connecting shell 41102, providing linear extension and retraction power to drive components such as the support sliding block 410 to perform linear motion. The follower plate 48 effectively diverts and transmits the power of the drive assembly 411, ensuring the synchronicity and coordination of the movements of the rotating rod 44 and the rotating long rod 49. The drive end of the drive assembly 411 is fixedly connected to the follower plate 48, and multiple connecting blocks a43 are fixedly connected to the outside of the drive assembly 411 and the outside of the follower plate 48. The connecting blocks a43 ensure... To ensure the stability and efficiency of power transmission between the follower plate 48 and the rotating rod 44 and the rotating rod 49, stable rotational support is provided for the rotating rod 44 and the rotating rod 49. Each connecting block a43 is externally rotatably connected to two rotating rods 44. The rotating rods 44 transmit power through rotational motion, realizing the motion linkage between related components, assisting in the adjustment of the internal structure of the stirring head 41 and enhancing the stirring action. In addition, the adjacent side of each connecting block a43 is fixedly connected to the outside of the follower plate 48, and the rotating rod 49 is rotatably connected to the outside of each connecting block a43. Each supporting sliding block 410 is fixedly connected to the adjacent side of each supporting sliding block b45, connecting the rotating rod 49 and the supporting sliding block 410, converting the rotational motion of the rotating rod 49 into the sliding motion of the supporting sliding block 410. Specifically, after the motor 41101 starts, it outputs rotational power, which is transmitted to the cylinder 41103 through the support connecting shell 41102. After receiving the rotational power, the cylinder 41103 converts it into linear extension and retraction power, and drives the support sliding block 410 to move linearly. At the same time, the drive end of the motor 41101 drives the follower plate 48 to rotate. The rotation of the follower plate 48 is transmitted to the rotating rod 44 and the rotating long rod 49 through the connecting block a43, so that they rotate synchronously. The rotation of the rotating long rod 49 is converted into the sliding motion of the support sliding block 410 through the connecting block b45, which further assists in the adjustment of the internal structure of the stirring head 41 and enhances the stirring action.

[0038] The implementation principle of this application embodiment is as follows: First, different external admixture solutions are introduced into the small mixing tank a24, and the flow frequency converter 8 accurately controls the process, laying the foundation for subsequent performance adjustment of the mixing system. After mixing, the mixture enters the support column 23, and is then started by the extraction pump 2601 and fed into the large mixing tank b32 inside the support base 31 through the feed pipe a2602. Simultaneously, the initial mixing of the multi-component materials is achieved inside the large mixing tank b32. Next, the mixture enters the large mixing tank c35 through the output pipe 3702, controlled by the control valve a3701, and water enters through the inlet 36. The mixture is diluted to a full tank. The dilution ratio can be dynamically adjusted according to the actual moisture content of the silt on site to ensure the compatibility of the mixture with the silt. At the same time, the flow rate of the diluted solution in the large mixing tank C35 is adjusted with the help of the slurry delivery frequency controller 8. For silt layers of different depths, the slurry delivery frequency controller 8 can adjust the delivery pressure and flow rate to ensure that the slurry can penetrate evenly to the specified depth and avoid uneven solidification caused by depth differences. Secondly, with the use of the tracked excavator 6, the working depth and mixing intensity of the mixing head 41 can be flexibly adjusted according to the irregularity of the silt depth. Combined with the dynamic adjustment of the slurry delivery system, it can effectively adapt to the construction needs under the complex geological conditions of the intertidal mudflat area.

[0039] Secondly, while the mixing head 41 is in use, it is connected to the tracked excavator 6 through the protective support shell 42. At the same time, the cylinder 41103 is activated, pushing the follower plate 48 to extend and retract vertically. Simultaneously, the cylinder 41103 drives the rotating rod 44 and the rotating long rod 49 to open and close, thereby driving the support sliding block 410 to open and close. Meanwhile, a limit groove 46 is opened inside the mixing head 41. When the support sliding block 410 opens and closes, the limit block 47 is limited inside the limit groove 46 to prevent the mixing head 41 from falling off during rotation. This not only ensures the safety of equipment operation but also enhances the reliability of the operation process and saves replacement time.
