Description

Technical Field

[0001] This invention relates to the field of soil and rock foundation treatment technology, and in particular to a soil cutting device, a seepage barrier construction equipment, and a seepage barrier construction method based on the TRD (Trench Cutting Re-mixing Deep Wall Method). Background Technology

[0002] A patent titled "A Chain Excavator" has been published in the Chinese Patent Database. The publication (announcement) number is CN102561437B, and the publication (announcement) date is May 14, 2014. This chain excavator discloses a split bucket and a method for unloading material by pushing the split buckets separately using hydraulic cylinders. When unloading soil, one bucket is first moved above ground level. Then, the chute is moved under the bucket, and the hydraulic cylinder is activated to open the right half of the bucket to unload soil. After unloading, the bucket is closed by the pull-back force of the hydraulic cylinder, and the bucket is moved out of the chute. The hydraulic motor is then activated to dig soil in the other bucket. When the other bucket emerges from the ground, the same method is used to unload soil, and this cycle is repeated.

[0003] As can be seen from the above, this chain excavator stops rotating after digging, then unloads the soil, and then the chain rotates to dig again after unloading. The digging and unloading processes are intermittent and cannot be continuous, which reduces the efficiency of the operation. Summary of the Invention

[0004] This application provides a soil cutting device, a seepage-proof curtain construction equipment, and a seepage-proof curtain construction method to achieve continuous cutting and excavation and soil unloading without the need for hydraulic cylinder-assisted soil unloading, and to simultaneously carry out grouting and slag removal operations.

[0005] The first aspect of this application provides a soil cutting device, comprising: The conveying mechanism includes: a guide frame and a track, the track being rotatably mounted on the guide frame and disposed in a trench, the track having a soil-shoveling side and a reset side; A soil-cutting mechanism, at least one of which is connected to the track, includes: a shovel head, a hook, a reset member, a limiting member, and a trigger. The shovel head and the hook are both hinged to the track. The front end of the hook is used to hook the shovel head. The reset member and the limiting member are both disposed between the track and the hook. The reset member and the shovel head both apply an external force to the hook in the direction of the limiting member. The limiting member is used to limit the rotation of the hook. The trigger is disposed on the soil-cutting side and connected to the guide frame. The trigger is disposed in the movement path of the tail of the hook. The trigger is used to drive the hook to rotate and disengage the hook from the shovel head. When the shovel head moves to the reset side, the shovel head rotates under its own weight and squeezes the hook. The hook rotates and re-engages the shovel head with the hook, limiting its position.

[0006] The beneficial effects of the above embodiments are as follows: 1. This anti-seepage curtain construction equipment can cut and unload soil, significantly improving construction efficiency; 2. The shovel head cuts the soil in the trench and transports the soil to the outside of the trench. During this process, the hook connects the external force of cutting the soil to the limiting component. The limiting component limits the shovel head to remain stable during the cutting process, thus ensuring the stability of the cutting process. 3. The triggering element forces the hook to move, unlocking the shovel head. The shovel head rotates rapidly and unloads the soil. When the shovel head moves to the reset side, it can rotate under its own weight and simultaneously hook back into place via the hook. This achieves automatic adjustment of the shovel head dumping the soil and re-entering the cutting state. In other words, the mechanical automatic hook structure eliminates the need for a hydraulic system, reducing equipment costs and failure rates, and improving the ease of use of the product.

[0007] Based on the above embodiments, the embodiments of this application can be further improved as follows: In one embodiment of this application, it further includes: a hanging rod, which is hinged to the track; the shovel head is connected to the hanging rod; and the hook-connector hooks onto the hanging rod. The beneficial effect of this step is that by configuring the hanging rod, the connection and separation functions of the shovel head and the hook-connector are realized.

[0008] A second aspect of this application provides a seepage-proof curtain construction device, which employs the aforementioned soil cutting device and further includes: A slag removal device is connected to the conveying mechanism and is used to remove slag and soil from the trench. The grouting device is located behind the slag removal device and is used to perform grouting operations in the trench.

[0009] The beneficial effects of the above embodiments are: to achieve continuous operation of cutting, unloading soil, cleaning debris and grouting, which significantly improves construction efficiency.

[0010] Based on the above embodiments, the embodiments of this application can be further improved as follows: In one embodiment of this application: the slag removal device includes: a slag discharge pipe and a pump body, the pump body being connected to the slag discharge pipe, and the slag discharge pipe being connected to the conveying mechanism. The beneficial effect of this step is that the pump body provides suction, allowing the slurry in the trench to be discharged through the slag discharge pipe.

[0011] In one embodiment of this application: the grouting device includes: an isolation component and a grouting pipe. The isolation component is connected to the conveying mechanism. The isolation component divides the trench into a grouting zone and a cutting zone. The grouting pipe is disposed in the grouting zone. The beneficial effect of this step is that by dividing the trench into zones using the isolation component, the stability of the grouting and cutting / discharging operation environment is improved, and interference between the two operation zones is avoided.

[0012] In one embodiment of this application: the isolation assembly includes: a column, a slide, and a seal. The column is connected to the conveying mechanism, the slide is connected to the lower end of the column and contacts the bottom of the groove, and the seal is connected to both sides of the column and the slide. The beneficial effects of this step are: the slide improves the smoothness of the isolation assembly's movement in the groove, and the seal improves the isolation effect of the isolation assembly.

[0013] The third aspect of this application provides a method for constructing a seepage-proof curtain, using the aforementioned seepage-proof curtain construction equipment, comprising the following steps: S1: The conveying mechanism drives the shovel head to move, and on the shovel side, the shovel head cuts the soil and transports it to the outside of the trench; S2: The trigger drives the hook to rotate, causing the shovel head to disengage from the hook, and the shovel head rotates to unload the material; S3: On the reset side, the shovel head rotates under its own weight and drives the hook to rotate, and the shovel head and the hook are re-hooked to form an integral structure; S4: The sludge removal device discharges the mud from the trench; S5: The grouting device injects filler into the trench.

[0017] In this application, unless otherwise expressly specified and limited, the terminology used should be interpreted broadly. For example, a connection can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of different terms in this invention according to the specific circumstances, and the scope of the specific meaning should be limited to achieving the functions of this application.

[0018] In the description of this application, it should be understood that the directional terms or positional relationships described are based on the orientation or positional relationships shown in the accompanying drawings, or based on the orientation or positional relationships in actual use, and are only for the purpose of facilitating the description of the contents of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0019] Example 1 like Figure 1-3As shown, a soil-cutting device includes: a conveying mechanism 1 and a soil-cutting mechanism 2. The conveying mechanism 1 includes: a guide frame 101 and a track 102. The track 102 is rotatably mounted on the guide frame 101 and is disposed in a trench 3. The track 102 has a shoveling side and a resetting side. The soil-cutting mechanism 2 has at least one component connected to the track 102. The soil-cutting mechanism 2 includes: a shovel head 201, a hook 202, a resetting component 203, a limiting component 204, and a triggering component 205. The shovel head 201 and the hook 202 are both hinged to the track 102. The front end of the hook 202 is used to hook the shovel head 201. The resetting component 203 and the limiting component 204 are both disposed on the track 102 and the hook 205. Between the connecting parts 202, the reset part 203 and the shovel head 201 both apply an external force to the hook connecting part 202 in the direction of the limiting part 204. The limiting part 204 is used to limit the rotation of the hook connecting part 202. The trigger part 205 is set on the shoveling side and connected to the guide frame 101. The trigger part 205 is set in the movement path of the tail of the hook connecting part 202. The trigger part 205 is used to drive the hook connecting part 202 to rotate and cause the hook connecting part 202 to disengage from the shovel head 201. When the shovel head 201 moves to the reset side, the shovel head 201 rotates under its own weight and squeezes the hook connecting part 202. The hook connecting part 202 rotates and re-engages the shovel head 201 with the hook connecting part 202 for limiting.

[0020] Specifically, such as Figure 1 As shown, the conveying mechanism 1 is a chain drive mechanism, which also includes: a driving wheel 103 and a driven wheel 104. The track 102 is a chain. The driving wheel 103 is rotatably mounted on the upper end of the guide frame 101, and the driven wheel 104 is rotatably mounted on the lower end of the guide frame 101. The chain is wound around the driving wheel 103 and the driven wheel 104. The driving wheel 103 is driven by a driving component, which is a motor. The rotation of the driving wheel 103 drives the chain to move, and the chain drives the driven wheel 104 to rotate. The side of the chain located on the soil to be cut is the shoveling side. The shoveling side performs shoveling operations through the shovel head 201 and transports the soil to the outside of the trench 3. The other side of the chain away from the shoveling side is the reset side. The reset side achieves the re-hooking and positioning of the shovel head 201 and the hook member 202 through the weight of the shovel head 201.

[0021] Specifically, such as Figure 1 As shown, multiple soil cutting mechanisms 2 are evenly distributed along the length of track 102, thereby improving soil cutting efficiency.

[0022] Specifically, such as Figure 2 As shown, the soil cutting device also includes: a hanging rod 206, which is hinged to the track 102; a shovel head 201 connected to the hanging rod 206; and a hook connector 202 hooking the hanging rod 206.

[0023] Specifically, such as Figure 2As shown, the hanging rod 206 is rotatably connected to the bracket via a rotating shaft, the bracket is connected to the track 102, the shovel head 201 is fixed to the hanging rod 206, and the hook connector 202 has a hook head. The inner side of the hook head is used to hook the hanging rod 206, and the outer side of the hook head has a guide surface 207. When it is in the reset position, the guide surface 207 is used to contact the end of the hanging rod 206. The hook connector 202 is driven to rotate by the pressure of the guide surface 207, and the hanging rod 206 re-enters the inner side of the hook head.

[0024] Specifically, such as Figure 2 As shown, the limiting member 204 is fixed to the inner side of the track 102, and the hook member 202 is rotatably connected to the middle of the limiting member 204. The other end of the hook member 202 relative to the hook head is the pressure section 208, which is located in the area between the tracks 102. The surface of the limiting member 204 facing the pressure section 208 is the limiting end 209. The limiting end 209 contacts and limits the pressure section 208, thereby preventing the pressure section 208 from rotating further toward the limiting member 204.

[0025] Specifically, such as Figure 2 As shown, the reset component 203 is a tension spring. One end of the tension spring is connected to the inner side of the track 102, and the other end is connected to the pressure section 208. The tension spring applies tension to the pressure section 208, so that the pressure section 208 fits against the limiting end 209.

[0026] Specifically, such as Figure 3 As shown, the trigger 205 is a protrusion structure. The trigger 205 is connected to the upper end of the guide frame 101. During the rotation of the track 102, the trigger 205 is located in the path of the pressure section 208. By pressing the pressure section 208 downward through the trigger 205, the inner side of the hook 202 rotates downward and the outer hook head rotates upward, thereby disengaging the hook head from the hanging rod 206.

[0027] The working principle of this soil cutting device is as follows: The shovel head 201 cuts the soil in the trench 3 and transports the soil to the outside of the trench 3. During this process, the hook 202 transmits the external force of cutting the soil to the limiting member 204. The limiting member 204 limits the shovel head 201 to remain stable during the soil cutting process, thus ensuring the stability of the soil cutting process. The trigger member 205 forces the hook 202 to move, unlocking the shovel head 201. The shovel head 201 rotates rapidly and unloads the soil. When the shovel head 201 moves to the reset side, it can rotate under its own weight and be hooked and limited again by the hook 202. This achieves automatic adjustment of the shovel head 201 dumping the soil and re-entering the cutting state. That is, through the mechanical automatic hook structure, the hydraulic system is eliminated, reducing equipment costs and failure rates, improving the ease of use of the product, and enabling continuous cutting and unloading operations, significantly improving construction efficiency.

[0028] Example 2 like Figure 1-4 As shown, a seepage-proof curtain construction device adopts the soil cutting device disclosed in Embodiment 1, and further includes: a slag cleaning device 4 and a grouting device 5. The slag cleaning device 4 is connected to the conveying mechanism 1 and is used to clean the slag in the trench 3; the grouting device 5 is located behind the slag cleaning device 4 and is used to perform grouting operations in the trench 3.

[0029] Specifically, the soil cutting device, the slag removal device 4, and the grouting device 5 are all mounted on the engineering vehicle via brackets, and the engineering vehicle provides power for the movement of the entire device.

[0030] Specifically, such as Figure 1 As shown, the slag removal device 4 includes: a slag discharge pipe 401 and a pump body 402. The pump body 402 is connected to the slag discharge pipe 401, and the slag discharge pipe 401 is connected to the conveying mechanism 1. The pump body 402 provides suction, and the slurry in the trench 3 is discharged through the slag discharge pipe 401.

[0031] Specifically, such as Figure 1 As shown, the slag discharge pipe 401 includes a slurry discharge pipe and a slurry suction pipe. The slag discharge pipe 401 is connected to the outlet end of the pump body 402, and the slurry suction pipe is connected to the inlet end of the pump body 402. The pump body 402 can be a submersible pump, a mud pump, or other equipment. The slurry suction pipe extends to the bottom of the trench 3, and the slurry discharge pipe extends to the outside of the trench 3. Power is provided by the pump body 402 to extract the mud from the trench 3.

[0032] Specifically, such as Figure 1 As shown, the grouting device 5 includes: an isolation component 501 and a grouting pipe 502. The isolation component 501 is connected to the conveying mechanism 1. The isolation component 501 divides the trench 3 into a grouting zone and a cutting zone. The grouting pipe 502 is located in the grouting zone. By dividing the trench 3 into zones through the isolation component 501, the stability of the grouting and cutting operation environment is improved, and interference between the two operation zones is avoided, ensuring the quality of the curtain wall.

[0033] Specifically, such as Figure 1 , 4 As shown, the isolation assembly 501 includes: a column 503, a slide 504, and a seal 505. The column 503 is connected to the conveying mechanism 1. The slide 504 is a block structure, which can be a nylon block, a metal block, a plastic block, etc. The slide 504 is connected to the lower end of the column 503 and contacts the bottom of the groove 3. The seal 505 is connected to both sides of the column 503 and the slide 504. The slide 504 improves the smoothness of the movement of the isolation assembly 501 in the groove 3, and the seal 505 improves the isolation effect of the isolation assembly 501.

[0034] Specifically, such as Figure 4As shown, column 503 is an I-beam placed vertically. One side of the web of the I-beam is connected to grouting pipe 502 via connecting rod 506, and the other side is fixed to grouting pipe 502. Grouting hopper 507 is provided at the upper end of grouting pipe 502, through which filler is injected. Sealing element 505 is a flexible sealing rubber plate. The flange of the I-beam located in the grouting area is connected to the slide ram 504 with a flexible sealing rubber plate. The flexible sealing rubber plates in the three directions are an integral structure to improve the sealing effect.

[0035] Driven by an engineering vehicle, the entire device gradually moves towards the side to be shoveled. The shovel head 201 cuts the soil on the shoveling side, and the soil falls into the shovel head 201 or the bottom of the trench 3. When the shovel head 201 moves to the outside of the trench 3, the pressure section 208 is squeezed by the trigger 205, the hook rod 206 disengages from the hook, the shovel head 201 flips downward and dumps the soil inside, and when the shovel head 201 moves to the reset side, the shovel head 201 rotates under the action of gravity, the hook rod 206 squeezes the guide surface 207, and the hook... The connector 202 rotates again, and the end of the hanging rod 206 enters the inside of the hook and locks again. Through the repeated cycle of the above process, continuous soil cutting is carried out and the soil is transported to the outside of the trench 3, achieving the purpose of non-stop operation. At the same time, the pump body 402 provides suction to pump the mud from the bottom of the trench 3 to the outside of the trench 3. Meanwhile, the filling material is injected into the grouting area through the grouting pipe 502, thereby realizing continuous operation of cutting, unloading soil, cleaning slag and grouting, thus significantly improving construction efficiency.

[0036] Example 3 A method for constructing a seepage barrier curtain, using the seepage barrier curtain construction equipment disclosed in Example 2, includes the following steps: S1: The conveying mechanism 1 drives the shovel head 201 to move. On the shovel side, the shovel head 201 cuts the soil and transports it to the outside of the trench 3. S2: The trigger 205 drives the hook 202 to rotate, causing the shovel head 201 to disengage from the hook 202, and the shovel head 201 rotates to unload the material; S3: On the reset side, the shovel head 201 rotates under its own weight and drives the hook 202 to rotate, and the shovel head 201 and the hook 202 re-hook together to form an integral structure. S4: The sludge removal device 4 discharges the mud from the trench 3; S5: Grouting device 5 injects filler into trench 3.

[0037] Specifically, steps S4 and S5 are performed simultaneously during the soil cutting process of the soil cutting device.
