Description

Technical Field

[0001] The invention relates to the technical field of guide wall groove excavation, in particular to an underground continuous wall guide wall groove excavation device. Background Art

[0002] TRD cement soil anti-seepage wall (construction method of pouring underground continuous wall reinforced with cement) uses chain saw cutters as the main machine. During the insertion into the foundation, the chain saw cutters are connected to the main machine. The revolving cutter chain saw can move vertically or horizontally to cut the underground soil, and cement is used as a hardener. The seamless cement soil wall of the TRD method has an excellent water-stopping effect and a retaining function. It replaces retaining structures such as ground-connected walls, cast-in-place piles, and three-axis mixing piles (SMW method). The cutter cuts the soil at the construction site according to the designed depth and the designed width of the retaining wall. At the same time, the cement slurry hardener is injected into the soil at the end of the cutter, and high-pressure air is injected to fully mix the cement slurry with the in-situ soil, stir and consolidate the in-situ soil, and thus form a continuous wall of equal thickness underground. During the specific construction, two corresponding grooves are first drilled out by a drilling rig, and then the soil in the two grooves is grabbed by a hydraulic bucket trencher to form a guide wall groove. Then, suitable materials such as reinforced concrete are poured in the guide wall groove to form an underground continuous wall with anti-seepage, soil retaining and load-bearing functions.

[0003] At present, when digging the soil inside the guide wall groove, a bucket is used for digging. After the digging is completed, the soil is lifted and poured into the dump truck, and then the bucket returns to the guide wall groove to dig the soil. The back and forth operation is repeated, which is time-consuming and labor-intensive, and reduces the overall work efficiency. At the same time, when it is necessary to dig the soil on the other side of the guide wall groove, it is necessary to change the position of the crane equipment to adjust the direction of the bucket. Such back and forth operation is very inconvenient. At the same time, when digging, it is not convenient to extract the underground seepage water well, which causes the excavated soil, mud and water to mix, increasing the difficulty of digging.

Belt pulleys 207 are respectively installed at one end of the machine 205 and the two shaft members 202, and the two belt pulleys 207 are connected by a driving belt 206. Since the digging teeth 204 on the two transmission members 203 are staggered, the two digging teeth 204 can cross each other without obstruction. Through the reverse synchronous operation of the two driving motors 205, the two transmission members 203 are synchronously rotated in the opposite direction with the cooperation of the driving belt 206 and the belt pulley 207.

The two gear plates 305 are meshed with each other. 01 The top is connected with a pull rope 302 through a pulley group. The installation of the fixed shaft 303 facilitates the rotation connection of the fixed seat 301. The installation of multiple pull ropes 302 facilitates the connection with an external crane to realize the suspension control of the casing 1, which is beneficial to the lifting and lowering of the casing 1 for digging.

The scrapers 403 are comb-mounted structures. One end of the scrapers 403 inside the two housings 1 respectively penetrates the guide grooves 402 and extends to the inner sides of the digging teeth 204. The digging teeth 204 and the scrapers 403 are staggered and slidably connected. Then, by installing the two cover shells 401, it is convenient to connect the two scrapers 403, and by opening the guide groove 402, the scraper 403 is convenient to extend into the inside of the casing 1. By rotating the transmission member 203, the plurality of digging teeth 204 pass through the scraper 403 in sequence, so that the scraper 403 can scrape the soil on the digging teeth 204. The scraped soil will be on the scraper 403. Since the scraper 403 has a certain slope, the soil can be introduced into the bottom inner side of the cover shell 401 through the scraper 403 and the guide groove 402 for storage.

[0029] Specifically, Figure 8 and Fig.10 As shown, the locking mechanism 6 includes a positioning groove 603, and positioning grooves 603 are provided at both ends of the top of the casing 1. One side of the top of the cover shell 401 is a "7"-shaped structure. One side of the top of the cover shell 401 is engaged with the inside of the cover shell 401. Through the opening of the positioning groove 603, after the cover shell 401 is engaged with the side wall of the casing 1, the top of the cover shell 401 is engaged with the inside of the positioning groove 603 to limit the position, so that the connection between the cover shell 401 and the casing 1 is more stable.

[0030] Specifically, Figure 1 , Figure 2 , Figure 8 , Fig. 9 and Fig.10 As shown, symmetrical bayonet pins 604 are respectively installed on the inner sides of both ends of the top of the casing 1, and the bayonet pins 604 are of "L"-shaped structure. The bayonet pins 604 are slidably connected to the inside of the casing 1 through a conflict spring 605. A lock groove 602 is provided at the center of one side of the top of the cover 401. One end of the bottom of the bayonet pin 604 extends to the outside of the casing 1 and conflicts with the inside of the lock groove 602. One end of the bottom of the bayonet pin 604 is of a trapezoidal structure. The top of the bayonet pin 604 extends to the outside of the top of the casing 1. A push block 601 is installed on the top of the bayonet pin 604. When the positioning groove 603 is engaged, the side wall of the cover shell 401 contacts and contracts the latch pin 604, making it convenient for the cover shell 401 to be engaged with the positioning groove 603. The latch pin 604 is inserted into the locking groove 602 under the action of the resistance spring 605, so as to limit the cover shell 401 and prevent it from sliding and disassembling. By pushing the push block 601, the push block 601 drives the latch pin 604 to slide away from the elastic force of the resistance spring 605, and the latch pin 604 is separated from the locking groove 602, making it convenient for the cover shell 401 to slide out, disassemble and maintain.

[0031] Specifically, Figure 1 , Figure 8 , Fig. 9 and Fig.13As shown, the conveying mechanism 5 includes a sleeve 501, and the centers of the two cover shells 401 are respectively fixedly connected with the sleeves 501, the top of the sleeve 501 extends to the outside of the top of the casing 1, and the bottom of the sleeve 501 extends to one side of the scraper 403. The sleeve 501 is rotatably connected with a screw rod 502. A control motor 504 is installed on the inner side of the bottom of the cover shell 401. The bottom of the screw rod 502 is connected to the output shaft of the control motor 504. A feed trough 503 is provided on one side of the bottom of the sleeve 501. The feed trough 503 is located on one side of the bottom of the scraper 403. The installation of the sleeve 501 facilitates the rotatable connection of the screw rod 502. Through the operation of the control motor 504, the control motor 504 drives the screw rod 502 to rotate inside the sleeve 501. Through the rotation of the screw rod 502, the soil at the bottom of the cover shell 401 is lifted and exported by the screw rod 502 through the feed trough 503, so as to facilitate subsequent recovery.

[0032] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 8 , Fig. 9 , Fig.11 and Fig.12 As shown, the pumping mechanism 7 includes a delivery pipe 701, and two delivery pipes 701 are respectively installed on the two side walls of the housing 401.

The installation of the connecting block 703 facilitates fixing the conduit 702 on the outside of the casing 1, and enables the bottom of the delivery pipe 701 and the top of the conduit 702 to be inserted and engaged. With the cooperation of the sealing ring 704, the connection between the delivery pipe 701 and the conduit 702 is stable and has good sealing performance, so that the internal seepage water can be pumped out when digging inside the guide wall groove. The installation of the filter screen 705 facilitates filtering sand and gravel.

[0033] When the present invention is in use, since the digging teeth 204 on the two transmission members 203 are staggered and distributed with each other, the two digging teeth 204 can cross each other without obstruction. Through the reverse synchronous operation of the two driving motors 205, the two transmission members 203 are synchronously rotated in the opposite directions with the cooperation of the driving belt 206 and the belt pulley 207. The digging teeth 204 on the two transmission members 203 will be gathered inside the excavation port 201 and will be lifted upward after being overlapped. Through the continuous descent of the casing 1, the soil inside the guide wall groove can be continuously grabbed and lifted, and the operation is more convenient and efficient. It is beneficial for the two digging teeth 204 to lift the soil after overlapping without falling, and the digging teeth 204 can better grab and crush the soil inside the guide wall groove, thereby reducing the wear on the digging teeth 204.

The installation of multiple pull ropes 302 is conducive to the connection with the external crane, so as to realize the suspension control of the casing 1, which is conducive to the lifting and digging of the casing 1. When the orientation of the entire casing 1 needs to be adjusted, the casing 1 is lifted to a certain height through the pull rope 302. Through the operation of the stepper motor 304, with the cooperation of the two gear plates 305, the fixed shaft 303 is rotated, which is conducive to adjusting the angle of the casing 1. It is convenient to adjust the angle according to the position of the guide wall groove, and then insert it into the groove for digging. The installation of the two cover shells 401 is conducive to the connection of the two scrapers 403. The opening of the guide groove 402 is conducive to the extension of the scraper 403 to the inside of the casing 1. Through the rotation of the transmission member 203, multiple digging teeth are 204 passes through the scraper 403 in turn, so that the scraper 403 scrapes the soil on the digging tooth 204. The scraped soil will be on the scraper 403. Since the scraper 403 has a certain slope, the soil is introduced into the bottom inner side of the cover shell 401 through the scraper 403 and the guide groove 402 for storage. The opening of the card slot 404 facilitates the detachable card connection between the cover shell 401 and the outer wall of the casing 1, thereby facilitating the subsequent replacement and maintenance of the interior of the cover shell 401. The opening of the positioning groove 603 facilitates the card connection between the cover shell 401 and the side wall of the casing 1. The top of the cover shell 401 is card-limited with the inside of the positioning groove 603, so that the connection between the cover shell 401 and the casing 1 is more stable. When the cover shell 401 is carded with the positioning groove 603, the side wall of the cover shell 401 resists the card pin 604. The cover 401 is retracted to facilitate the engagement of the cover shell 401 with the positioning groove 603. The bayonet 604 is inserted into the locking groove 602 under the action of the resistance spring 605, so that the cover shell 401 is limited and cannot be slid and disassembled. By pushing the push block 601, the push block 601 drives the bayonet 604 to get rid of the elastic force of the resistance spring 605 and slide. The bayonet 604 is separated from the locking groove 602, which is convenient for the cover shell 401 to slide out and be disassembled for maintenance. The installation of the pipe sleeve 501 is conducive to the rotation connection of the spiral rod 502. By controlling the work of the motor 504, the motor 504 is controlled to drive the spiral rod 502 to rotate inside the pipe sleeve 501. Through the rotation of the spiral rod 502, the soil at the bottom of the cover shell 401 is lifted and discharged by the spiral rod 502 through the feeding trough 503, so as to facilitate subsequent recycling.The installation of the delivery pipe 701 facilitates the connection with the external water pump. The installation of the connection block 703 facilitates the fixing of the conduit 702 on the outside of the housing 1, and the bottom of the delivery pipe 701 is inserted and engaged with the top of the conduit 702. With the cooperation of the sealing ring 704, the connection between the delivery pipe 701 and the conduit 702 is stable and has good sealing performance, so that the internal seepage water can be pumped away when digging inside the guide wall groove. The installation of the filter screen 705 facilitates the filtering of sand and gravel.
