Description

Technical Field

[0001] The present invention relates to the technical field of soft soil solidification, and specifically to on-site soft soil solidification equipment. Background Art

[0002] Soft soil refers to clay in a soft plastic or fluid plastic state with a large natural water content, high compressibility, low bearing capacity, and very low shear strength. In modern society, many construction projects are carried out on soft soils such as tidal flats and silt lands. The properties of soft soil determine that construction teams cannot directly carry out construction on it. It is necessary to first solidify the soft soil to form a stable base with a certain bearing capacity, and then construction equipment can be driven into the construction site for construction. On-site soft soil solidification, simply speaking, is not to transfer the soil mass, but at the construction site, directly through grouting or powder spraying and mixing equipment, cement, fly ash and other solidifying agents are fully mixed with the soil mass to cause a chemical reaction, so as to achieve the purpose of dewatering and cementitious hardening of the site.

[0003] Conventional in-situ soft soil solidification is generally carried out by modifying an excavator to solidify the soft soil in-situ. The bucket of the excavator is removed, and then a mixing head with a mixing function is replaced. The soft soil is mixed through the mixing head. During the mixing process, powdery or slurry-like solidifying agents are mixed into the soft soil. Under the action of the solidifying agent, the solidification speed of the soft soil is accelerated. When carrying out in-situ solidification, the most important thing is to ensure that the solidifying agent and the soft soil are evenly mixed. In the prior art, there are mainly two ways to put the solidifying agent. One is to first sprinkle the powdery or slurry-like solidifying agent on the surface of the soft soil, and then mix the solidifying agent and the soft soil through a mixing device; the other is to fix the slurry outlet pipe of the solidifying agent on the mixing head and mix the soft soil and the solidifying agent while mixing. For the above two construction methods, in order to ensure the mixing effect, a large amount of time is required to mix the soft soil, and the construction efficiency is low. Summary of the Invention

[0004] The present invention provides on-site soft soil solidification equipment, which has the beneficial effect of high construction efficiency, and solves the problem that a large amount of time is required to mix the soft soil and the solidifying agent to ensure the mixing effect of the solidifying agent mentioned in the above background art.

[0017] The present invention has the following beneficial effects:

[0018] 1. For the in-situ soft soil solidification equipment, by providing a plow frame with a connecting arm, the plow frame can be fixed on the construction equipment through the connecting arm and move under the traction of the construction equipment. A plow head is provided at the bottom of the plow frame, and the side of the plow frame is also edge-treated to facilitate the movement of the device in soft soil. A fixed groove is provided inside the plow frame. During the movement of the plow frame, the soft soil will pass through the fixed groove. A stirring mechanism is provided at the fixed groove. The stirring mechanism includes a stirring shaft, and stirring blades are provided on the stirring shaft. The soft soil can be stirred by the stirring shaft with stirring blades;

[0019] In this technical solution, the stirring shaft is of a hollow structure, and a first slurry outlet is also provided on the stirring shaft. While stirring, the stirring shaft can also spray the paste-like curing agent into the soft soil, having a better mixing effect. In actual use, unlike traditional solidification equipment, the device of the present invention does not need to repeatedly stir the soft soil.

[0020] 2. For the in-situ soft soil solidification equipment, by providing a liquid supplement mechanism between the stirring mechanisms, the liquid supplement mechanism includes a support seat, one end of the support seat is communicated with a sealing cover, and slurry outlet assemblies are provided on both sides of the support seat. Through the slurry outlet assemblies, the slurry can be sprayed towards the direction of the stirring shaft, which cooperates with and complements the first slurry outlet, and can effectively improve the mixing effect of the soft soil and the curing agent;

A fixing groove 201 is provided inside the plow frame 2. During the movement of the plow frame 2, part of the soft soil will pass through the fixing groove 201. A stirring mechanism is provided at the fixing groove 201. The stirring mechanism includes a stirring shaft 4, and stirring blades 401 are provided on the stirring shaft 4. The soft soil can be stirred by the stirring shaft 4 with the stirring blades 401. Moreover, the stirring shaft 4 is hollow, and a first slurry outlet 402 is also provided on the stirring shaft 4. While stirring, the stirring shaft 4 can also spray the slurry-shaped curing agent into the soft soil, having a better mixing effect. In actual use, this device does not need to repeatedly stir the soft soil like traditional curing equipment. During its movement, through the stirring equipment in the fixing groove 201, the feeding and mixing of the curing agent can be completed, and the construction efficiency is higher.

[0036] Specifically, one end of the connecting arm 1 is fixed on the boom of the floating excavator.

[0038] Embodiment 2

[0039] This embodiment is an explanatory description based on Embodiment 1. Specifically, please refer to Figures 1 to 6 , a liquid supplement mechanism is provided between the stirring mechanisms, and the liquid supplement mechanism includes a support seat 10. The support seat 10 is of a hollow structure, and one end of the support seat 10 is communicated with the sealing cover 5. Slurry outlet components are provided on both the upper and lower sides of the support seat 10.

[0040] In this device, two stirring mechanisms are provided. In order to further improve the mixing effect of the curing agent, this technical solution also provides a rehydration mechanism between the stirring mechanisms. The rehydration mechanism includes a support seat 10. One end of the support seat 10 is connected to the sealing cover 5. Slurry discharge components are provided on both sides of the support seat 10. The slurry can be sprayed toward the stirring shaft 4 through the slurry discharge component. It cooperates and complements with the first slurry discharge nozzle 402, which can effectively improve the mixing effect of the soft soil and the curing agent.

[0041] Example 3

[0042] This example is an explanation based on Example 1. For details, please refer to Figures 1 to 6 The pulp discharge assembly includes a sleeve 11 and a support plate 12. The sleeve 11 is located outside the support base 10, and one end of the sleeve 11 is fixedly connected to the support base 10. A plurality of first openings 1101 are provided on the sleeve 11.

[0043] The support plate 12 is located inside the support base 10 and is elastically connected to the support base 10 via a first spring 13. The support plate 12 is provided with a plurality of conduits 14. One end of the conduit 14 passes through the support plate 12 and is inserted into the sleeve 11. The conduit 14 is provided with a plurality of second openings 1401. One end of the conduit 14 is a closed structure, and the other end of the conduit 14 is provided with a slurry inlet.

[0044] A first transmission mechanism is provided in the sealing cover 5, and the first transmission mechanism includes a cam 15 and a movable block 16. The movable block 16 is elastically connected to the plow frame 2 through a second spring 17, and the upper end of the movable block 16 is provided with a slanted top. The cam 15 is fixed to the end of the stirring shaft 4, and the cam 15 is in conflict with the movable block 16.

[0045] A second transmission mechanism is provided at one end of the support base 10, and the second transmission mechanism includes a transmission rod 24, one end of which is provided with an inclined block 25. The transmission rod 24 is elastically connected to the support base 10 via a third spring 18, and the transmission rod 24 abuts against the movable block 16. A protrusion 1201 is provided on the side of the support plate 12 away from the pulp discharge assembly. The protrusion 1201 is triangular in shape and abuts against the transmission rod 24.

[0046] The fixed groove 201 is a relatively closed space. When the soft soil passes through the fixed groove 201, the plow frame 2 and the support seat 10 can form a certain constraint on the soft soil, so that when the soft soil and the curing agent are stirred and mixed by the stirring mechanism, a better mixing effect can be achieved. However, when the stirring mechanism is working, the soft soil will be squeezed and will move toward the direction of the fluid replenishment mechanism, which may easily cause blockage of the slurry discharge component. For this reason, the present technical solution improves the slurry discharge component, which includes a sleeve 11 and a support plate 12. A conduit 14 is provided on the support plate 12. One end of the conduit 14 is inserted into the sleeve 11. A first opening 1101 is provided on the sleeve 11, and a second opening 1401 is provided on the conduit 14. Under normal circumstances, the first opening 1101 and the second opening 1401 are staggered.

[0047] When the stirring shaft 4 rotates, the cam 15 will be driven to rotate. Under the push of the cam 15, the movable block 16 will move downward. The lower end of the movable block 16 will conflict with the inclined block 25. Under the push of the movable block 16, the inclined block 25 will move toward the support plate 12 with the transmission rod 24. A triangular protrusion 1201 is provided at the end of the support plate 12. Under the push of the transmission rod 24, the support plate 12 opens. Driven by the support plate 12, the conduit 14 moves toward the sleeve 11. At this time, the first opening 1101 is aligned with the second opening 1401, and the slurry in the support seat 10 can flow out through the first opening 1101 and the second opening 1401. When the cam 15 no longer applies pressure to the movable block 16, the movable block 16 will return to its original position under the push of the second spring 17, and the support plate 12 will also return to its original position with the conduit 14 under the push of the first spring 13. At this time, the first opening 1101 and the second opening 1401 are staggered again, and this reciprocating cycle is repeated.

[0048] The present technical solution is provided with a slurry discharge assembly consisting of a sleeve 11 and a support plate 12, a conduit 14 is provided on the support plate 12, one end of the conduit 14 is inserted into the sleeve 11, a first opening 1101 is provided on the sleeve 11, and a second opening 1401 is provided on the conduit 14. Under normal circumstances, the first opening 1101 and the second opening 1401 are staggered. When the stirring shaft 4 rotates, it will be linked with the support plate 12 through the first transmission mechanism and the second transmission mechanism, and finally the support plate 12 is prompted to move with the conduit 14 toward the sleeve 11. At this time, the first opening 1101 is aligned with the second opening 1401, and the slurry in the support seat 10 can flow out through the first opening 1101 and the second opening 1401.

[0049] In this technical solution, the slurry discharging direction of the slurry discharging component is inconsistent with the stirring direction of the stirring mechanism, and the slurry discharging component discharges slurry intermittently. When no slurry is discharged, the first opening 1101 and the second opening 1401 are staggered, so that the slurry in the support seat 10 cannot flow out through the first opening 1101 and the second opening 1401, and the external soft soil and slurry cannot enter the support seat through the first opening 1101 and the second opening 1401, effectively reducing the risk of blockage of the slurry discharging component.

[0050] Embodiment 4

[0051] This embodiment is an explanatory description based on Embodiment 1. Specifically, please refer to Figures 1 to 6 , a soil loosening and distributing mechanism is provided on the lower side of the plow blade 3, and the soil loosening and distributing mechanism includes a fixing seat 19. The fixing seat 19 is of a hollow structure, and a plurality of second slurry discharging nozzles 20 are provided on both sides of the fixing seat 19. A scraping plate 21 is provided on one side of the second slurry discharging nozzle 20, and the scraping plate 21 is fixedly connected to the fixing seat 19.

[0052] The plow blade 3 is of a hollow structure, and a second slurry inlet 22 is provided at the upper end of the plow blade 3. The second slurry inlet 22 is communicated with the fixing seat 19 through a pipeline 23.

[0053] In order to reduce the resistance of the device when walking in soft soil, a conical plow head 9 is provided at the lower end of the device. Since the plow head 9 is conical, the stirring mechanism cannot stir this part of the soft soil, and the curing agent at the stirring shaft 4 cannot reach this position. In order to improve the overall soft soil curing effect, this technical solution provides a soil loosening and distributing mechanism at the position of the plow blade 3 close to the plow head 9. Through the soil loosening and distributing mechanism, on the one hand, the lower soft soil can be loosened, and on the other hand, a second slurry discharging nozzle 20 is also provided on the soil loosening and distributing mechanism. Through the second slurry discharging nozzle 20, the soft soil curing agent can be injected into the lower soft soil to improve the overall soil layer curing effect, and the use effect is better.

[0054] Specific working principle: When in use, the second slurry inlet 22 is externally connected to a slurry pump, and the slurry-like curing agent is sent into the fixing seat 19 through the slurry pump. A scraping plate 21 is provided on the outer side of the fixing seat 19, and the scraping plate 21 can play a role in loosening the soil. A second slurry discharging nozzle 20 is provided on the back of the scraping plate 21, and the slurry-like curing agent is sprayed out through the second slurry discharging nozzle 20 and then enters the soil layer to improve the curing effect of the soft soil.

[0055] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0056] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
