Description

Technical Field

[0001] The invention relates to the technical field of foundation construction, in particular to a coastal soft soil vacuum preloading foundation treatment and protection structure. Background Art

[0002] Coastal soft soil is a special type of soil formed under the specific environment of coastal areas. When constructing on coastal soft soil, it is necessary to reinforce it first. Currently, vacuum preloading foundation is usually used to reinforce coastal soft soil.

[0003] The vacuum preloaded foundation will first dig a sealing ditch around the soft soil that needs to be reinforced, then lay a sand cushion layer on the surface of the soft soil foundation that needs to be reinforced, and then build vertical drainage channels such as plastic drainage boards or sand wells, and then lay a sealing membrane on the sand cushion layer. After that, the air under the sealing membrane is extracted through a vacuum pump to form a pressure difference inside and outside the sealing membrane. Under the action of the pressure difference, the pore water pressure in the soil gradually decreases and the effective stress gradually increases, thereby consolidating the soil and increasing its strength.

[0004] After the sealing film is unfolded and laid on the sand cushion layer, it is necessary to manually insert the four sides of the sealing film into the sealing groove, and then bury the edge of the sealing film tightly in the sealing groove by backfilling clay, so as to ensure the airtightness of the sealing film. However, the above method of manually burying the sealing film is difficult to ensure the consistent burying effect of the four sides of the sealing film, which is easy to cause the sealing film to leak, thereby affecting the reinforcement effect. In addition, since the sealing film needs to cover the construction position as a whole, the entire sealing film is often the same size as the construction area, so that workers need to go around the sealing film to bury the edge of the sealing film, thereby reducing the construction efficiency.

[0017] The beneficial effects of the present invention are:

[0018] 1. The present invention adopts a lifting frame to drive two U-shaped frames and the plugging wheel to synchronously descend to a fixed position inside the sealing groove, so that the film pulling assembly can pull the sealing film into the inside of the sealing groove, and at the same time, the plugging wheel can plug the sealing film into the groove opened by the cutting block on the inner wall of the sealing groove, so that the edge of the sealing film can be plugged into the same height of the sealing groove, thereby ensuring the consistency of burying the edge of the sealing film and ensuring the sealing effect of the sealing film.

[0019] 2. The present invention uses a transport vehicle to drive the film pulling assembly, the grooving block and the plugging wheel to move along the sealing groove, so that the plugging wheel can automatically plug the edge of the sealing film into the inner wall of the sealing groove, eliminating the manual operation of burying the sealing film, thereby increasing the construction efficiency, and through the grouting assembly, while plugging the sealing film, clay slurry can be poured into the interior of the sealing groove, thereby sealing the sealing film inside the sealing groove, thereby further increasing the construction efficiency by performing the film plugging and grouting simultaneously.

[0020] 3. The present invention adopts a tamping assembly to tamp the edge of the sealing film when the plugging wheel plugs the edge of the sealing film into the inner wall of the sealing groove, so that the sealing film and the edge of the sealing groove fit more closely. In addition, after the plugging wheel plugs the edge of the sealing film into the inner wall of the sealing groove, the sealing film on the inner wall of the sealing groove can be scraped by the anti-slip block to prevent the rotating plugging wheel from pulling the sealing film out of the inner wall of the sealing groove, thereby ensuring the tightness of the connection between the sealing film and the sealing groove.

DETAILED DESCRIPTION

[0033] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0034] See also Figure 1 A coastal soft soil vacuum preloading foundation treatment and protection structure comprises a transport vehicle 1, a slurry storage tank 2 is fixedly installed on the transport vehicle 1, a lifting frame 3 is provided on the front side of the transport vehicle 1 for sliding up and down through a guide column, a hydraulic telescopic rod 11 is fixedly installed on the transport vehicle 1, the telescopic section of the hydraulic telescopic rod 11 is fixedly connected to the lifting frame 3, a guide mechanism 4 for guiding a sealing film is provided on the right front part of the lifting frame 3, and a sealing mechanism 5 for sealing the sealing film is provided on the left front part of the lifting frame 3.

[0035] When the sealing film needs to be buried inside the sealing groove, the transport vehicle 1 is first moved to one side of the sealing groove, so that the transport vehicle 1 drives the lifting frame 3 to move to the top of the sealing groove, and then the telescopic section of the hydraulic telescopic rod 11 is retracted to drive the lifting frame 3 to move downward to the inside of the sealing groove. The lifting frame 3 drives the guide mechanism 4 and the sealing mechanism 5 to move to the inside of the sealing groove. Then the operator pulls the edge of the sealing film to the inside of the guide mechanism 4, and then starts the transport vehicle 1 to move along the trajectory of the sealing groove.

[0036] The transport vehicle 1 drives the guide mechanism 4 and the sealing mechanism 5 to move synchronously through the lifting frame 3, so that the guide mechanism 4 continuously pulls the sealing film into the inside of the sealing groove, and the sealing mechanism 5 inserts the sealing film pulled into the inside of the sealing groove into the inner wall of the sealing groove, and at the same time pours clay slurry into the inside of the sealing groove, so that the sealing film is tightly connected with the sealing groove.

[0037] See also Figure 1 , Figure 2 and Figure 3 The guide mechanism 4 includes a C-shaped frame 41 symmetrically arranged at the lower right side of the lifting frame 3, the vertical section of the front side of the C-shaped frame 41 is lower than the vertical section of the rear side, the vertical section of the rear side of the C-shaped frame 41 is fixedly connected to the lifting frame 3, a moving block 42 is slidably arranged on the vertical section of the rear side of the left C-shaped frame 41 along the vertical direction, a No. 1 threaded rod 411 is rotatably arranged on the vertical section of the rear side of the left C-shaped frame 41, the No. 1 threaded rod 411 is threadedly connected with the moving block 42, an upper pressure roller 43 is rotatably arranged at the front part of the moving block 42, a gap is left between the front end of the upper pressure roller 43 and the front vertical section of the left C-shaped frame 41, a lower abutting roller 44 is rotatably arranged on the inner lower side of the left C-shaped frame 41, spiral patterns are arranged on the outer sides of the upper pressure roller 43 and the lower abutting roller 44, and the spiral patterns on the upper pressure roller 43 and the lower abutting roller 44 rotate in opposite directions.

[0038] Continue reading Figure 1 , Figure 2 and Figure 3 The guide mechanism 4 also includes a film-pulling assembly 45 arranged on the right U-shaped frame 41. The film-pulling assembly 45 includes a conveying roller 451 that is symmetrically rotated on two vertical sections of the right U-shaped frame 41. A belt 452 is wound around the outer sides of the two conveying rollers 451. Anti-skid patterns are arranged at equal intervals on the outer sides of the belt 452 along its track. The anti-skid patterns rotated to the upper side of the belt 452 are gradually tilted backward from left to right. An execution motor 453 is fixedly installed on the right side of the right U-shaped frame 41, and the output shaft of the execution motor 453 is fixedly connected to the conveying roller 451 on the rear side.

[0039] Continue reading Figure 1 , Figure 2 and Figure 3The guide mechanism 4 also includes a detection component 46 arranged on the right side C-shaped frame 41. The detection component 46 includes a sliding block 461 slidably arranged on the rear vertical section of the right side C-shaped frame 41 along the vertical direction. A pushing spring is arranged between the sliding block 461 and the right side C-shaped frame 41. A pressing roller 462 is rotatably arranged at the front of the sliding block 461. A rangefinder 463 is fixedly installed on the right side of the rear vertical section of the right side C-shaped frame 41, and an electric push rod 464 is fixedly installed on the left side of the rear vertical section of the right side C-shaped frame 41.

[0040] When the lifting frame 3 is extended downward into the interior of the sealing groove, the lifting frame 3 drives the two U-shaped frames 41 to extend into the interior of the sealing groove synchronously, and then the operator manually pulls the edge of the sealing film between the belt 452 and the pressure roller 462, and at the same time makes the edge of the sealing film located between the upper pressure roller 43 and the lower pressure roller 44, so that the push spring pushes the sliding block 461 downward through its own elastic force, and the sliding block 461 drives the pressure roller 462 to push the sealing film against the belt 452.

[0041] Subsequently, the operator manually rotates the No. 1 threaded rod 411, so that the No. 1 threaded rod 411 drives the upper pressure roller 43 to move downward through the moving block 42, so that the upper pressure roller 43 pushes the sealing film to press against the lower pressure roller 44. When the transport vehicle 1 moves along the trajectory of the sealing groove, the execution motor 453 is started to drive the rear conveying roller 451 to rotate, and the conveying roller 451 drives the belt 452 to rotate, so that the belt 452 pulls the sealing film toward the sliding block 461 through the anti-slip grooves thereon, and then the edge of the sealing film is continuously pulled into the inside of the sealing groove.

[0042] It should be noted that the obliquely arranged anti-skid patterns can not only pull the sealing film, but also enable the sealing film to move in the left-right direction on the belt 452, thereby preventing the belt 452 from pulling the sealing film off-center.

[0043] When the transport vehicle 1 moves, it drives the upper pressure roller 43 and the lower pressure roller 44 to move synchronously, so that the upper pressure roller 43 and the lower pressure roller 44 move relative to the sealing film, so that the sealing film drives the upper pressure roller 43 and the lower pressure roller 44 to rotate synchronously in the opposite direction through friction. The rotating upper pressure roller 43 and the lower pressure roller 44 can pull the edge of the sealing film toward the moving block 42 through the spiral patterns thereon, thereby further increasing the pulling effect on the sealing film and preventing the sealing film from falling off the U-shaped frame 41.

[0044] A controller is fixedly installed on the right side of the U-shaped frame 41. The controller is not shown in the figure. The controller is connected to the distance meter 463 and the electric push rod 464 through wires. When the sliding block 461 drives the pressure roller 462 to press against the belt 452, the height of the sliding block 461 can be detected in real time through the distance meter 463. When the folded sealing film moves between the pressure roller 462 and the belt 452, the folded sealing film pushes the pressure roller 462 upward, and the pressure roller 462 drives the sliding block 461 to move upward synchronously, so that the thickness of the sealing film at the detection point of the distance meter 463 increases, so that the controller determines that the sealing film is in a folded state, and then the controller controls the telescopic section of the electric push rod 464 to extend, so that the electric push rod 464 drives the pressure roller 462 to press against the sealing film by pushing the sliding block 461, so that the pressure roller 462 can drive the sealing film to move synchronously with the transport vehicle 1, thereby unfolding the folded sealing film.

[0045] It should be noted that when the telescopic section of the electric push rod 464 extends downward, the folded position of the sealing film moves to between the two U-shaped frames 41 due to the movement of the transport vehicle 1, so that the pressing roller 462 pulls the sealing film to unfold the folded position of the sealing film.

[0046] See also Figure 1 , Figure 2 and Figure 4 The sealing mechanism 5 includes a fixed tube 51 fixedly installed in the middle of the lifting frame 3, a mounting frame 52 is fixedly installed together with the fixed tube 51 and the lower part of the lifting frame 3, a plugging wheel 58 is rotatably provided on the right side of the mounting frame 52, a cutting block 53 is fixedly installed on the front side of the left U-shaped frame 41, an anti-slip block 54 is fixedly installed on the front side of the middle of the mounting frame 52, the right side of the cutting block 53 is a three-sided cone structure, and a cutting edge is provided on the front side of the three-sided cone structure of the cutting block 53.

[0047] When the edge of the sealing film is pulled to the inside of the C-shaped frame 41, the sealing film is located in front of the plugging wheel 58 and the anti-slip block 54, and the sealing film is located at the rear side of the cutting block 53. When the transport vehicle 1 starts to move along the trajectory of the sealing groove, the transport vehicle 1 drives the front side of the C-shaped frame 41 to fit the inner wall of the sealing groove through the lifting frame 3, so that the C-shaped frame 41 on the left drives the cutting block 53 to extend into the inner wall of the sealing groove, so that the transport vehicle 1 cuts the inner wall of the sealing groove through the cutting block 53, and then the plugging wheel 58 pushes the sealing film into the groove cut on the sealing groove, and then presses and pulls the sealing film through the front side of the anti-slip block 54 to prevent the rotating plugging wheel 58 from pulling the sealing film out of the groove of the sealing groove.

[0048] See also Figure 1 , Figure 4 , Figure 5 and Figure 6The sealing mechanism 5 also includes a tamping assembly 55 arranged inside the plug edge wheel 58. The tamping assembly 55 includes tamping pieces 551 arranged on the plug edge wheel 58 at equal intervals along the circumference thereof. The tamping pieces 551 are slidably connected to the plug edge wheel 58 along the radial direction thereof. A coil spring is arranged between the tamping piece 551 and the plug edge wheel 58. A track disc plate 552 is rotatably arranged inside the plug edge wheel 58. The upper side of the track disc plate 552 is fixedly connected to the lifting frame 3 through a fixing rod. A track groove is opened on the track disc plate 552. The tamping piece 551 slides inside the track groove through a raised column fixedly installed on the side close to the axis of the plug edge wheel 58. The rear side of the track groove is circular, and the front side of the track groove is a right-angled triangular groove structure with the inclined surface facing the left side.

[0049] When the plug wheel 58 pushes the sealing film into the groove of the sealing groove, the friction force of the sealing film on the plug wheel 58 drives it to rotate, and the plug wheel 58 drives the tamping piece 551 thereon to rotate synchronously, and the tamping piece 551 drives the raised column thereon to move along the track groove of the track plate 552. When the raised column moves to the circular structure part of the track groove, the track groove pulls the tamping piece 551 through the raised column to a position close to the track plate 552, and compresses the coil spring at the same time. When the tamping piece 551 moves to the front, the tamping piece 551 drives the raised column thereon to move to the right-angled triangular groove structure of the track groove, so that the coil spring pushes the tamping piece 551 forward, and then the tamping piece 551 tamps the sealing film, so that the sealing film and the groove wall of the sealing groove fit more closely.

[0050] See also Figure 1 , Figure 2 , Figure 7 and Figure 8 The sealing mechanism 5 also includes a pushing assembly 56 arranged on the anti-slip block 54, and the pushing assembly 56 includes a rotating plate 561 which is symmetrically hinged on the right part of the anti-slip block 54, and a pushing plate 562 is hinged on the left end of the rotating plate 561. A connecting plate 563 is hinged between the left side of the pushing plate 562 and the anti-slip block 54, and the connecting plate 563 is parallel to the rotating plate 561 on the same pushing plate 562. The left side of the cutting block 53 is a rectangular block structure, and triangular blocks 531 are fixedly installed on the upper and lower side surfaces of the rectangular block structure of the cutting block 53. A cutting edge is opened on the right side of the triangular block 531, and a driving part 564 for driving the rotating plate 561 is arranged on the mounting frame 52.

[0051] See also Figure 7 and Figure 8The driving part 564 includes a transmission rod 5641 fixedly mounted on the rotating plate 561, the transmission rod 5641 is located at the coaxial position of the hinge between the rotating plate 561 and the anti-dropping block 54, the rear end of the transmission rod 5641 rotates and is inserted into the rear side of the mounting frame 52, a rotating gear 5642 is fixedly mounted on the rear end of the transmission rod 5641, a bidirectional rack 5643 is provided on the rear side of the mounting frame 52 for sliding along the left and right directions, the bidirectional rack 5643 is located between the two rotating gears 5642 and meshes with them at the same time, a No. 2 threaded rod 5644 is rotatably provided on the mounting frame 52, and the No. 2 threaded rod 5644 is threadedly connected to the bidirectional rack 5643.

[0052] When the groove cutting block 53 cuts the inner wall of the sealing groove, the groove cutting block 53 cuts a rectangular groove on the upper and lower side walls of the cut groove through the two triangular blocks 531 thereon. When the anti-dropping block 54 extends into the groove on the sealing groove, the operator manually rotates the second threaded rod 5644, so that the second threaded rod 5644 drives the two-way rack 5643 to move to the right, and the two-way rack 5643 drives the two transmission rods 5641 to rotate synchronously in the opposite direction through the two rotating gears 5642. The transmission rod 5641 drives The movable rotating plate 561 rotates synchronously. Since the rotating plate 561, the pushing plate 562, the connecting plate 563 and the anti-slip block 54 form a parallelogram structure, the rotating plate 561 drives the pushing plate 562 to maintain a horizontal state and move in a direction away from the anti-slip block 54, so that the pushing plate 562 extends into the interior of the groove cut by the triangular block 531, and then the pushing plate 562 pushes the sealing film into the interior of the groove cut by the triangular block 531, thereby increasing the contact area between the sealing film and the sealing groove, thereby increasing the airtightness of the sealing film.

[0053] See also Figure 1 The sealing mechanism 5 also includes a grouting assembly 57 arranged on the lifting frame 3. The grouting assembly 57 includes a No. 1 pipe 571 fixedly installed on the front left side of the mounting frame 52. The front side of the No. 1 pipe 571 is a three-way structure connected to the outside upward, downward and left.

The rear end of the No. 2 pipe 572 is connected to the slurry storage tank 2 through a hose.

[0054] When the anti-slip block 54 extends into the groove on the sealing groove, the lifting frame 3 drives the three-way structure of the No. 1 pipe 571 to extend into the groove on the sealing groove synchronously through the mounting frame 52, and at the same time, the upper and lower outlets of the three-way structure of the No. 1 pipe 571 are aligned with the position of the groove cut by the triangular block 531. Then, the slurry storage tank 2 pours the clay slurry into the interior of the No. 1 pipe 571 and the No. 2 pipe 572 respectively, so that the No. 1 pipe 571 directly pours the clay slurry into the interior of the groove on the sealing groove, thereby sealing the sealing film inside the groove of the sealing groove wall, and at the same time, the No. 2 pipe 572 directly pours the clay slurry into the interior of the sealing groove, so that the sealing film is sealed inside the sealing groove.

[0055] When burying the sealing film into the interior of the sealing groove, the present invention also includes the following steps: the first step is to move the transport vehicle 1 to one side of the sealing groove, so that the transport vehicle 1 drives the lifting frame 3 to move to the top of the sealing groove, and then retract the telescopic section of the hydraulic telescopic rod 11 to drive the lifting frame 3 to move downward to the interior of the sealing groove, and the lifting frame 3 drives the two U-shaped frames 41 to extend into the interior of the sealing groove synchronously.

[0056] In the second step, the operator manually pulls the edge of the sealing film between the belt 452 and the pressure roller 462, and at the same time makes the edge of the sealing film located between the upper pressure roller 43 and the lower pressure roller 44. The operator manually turns the No. 2 threaded rod 5644 to drive the push plate 562 to extend into the groove cut by the triangular block 531.

[0057] The third step is to move the transport vehicle 1 along the trajectory of the sealing groove, and start the execution motor 453 to drive the belt 452 to pull the sealing film, so that the edge of the sealing film is continuously pulled into the inside of the sealing groove, and the upper pressure roller 43 and the lower resistance roller 44 can prevent the sealing film from falling off the U-shaped frame 41 through the spiral patterns thereon.

[0058] In the fourth step, when the folded sealing film moves between the pressing roller 462 and the belt 452, the electric push rod 464 drives the pressing roller 462 to press the sealing film tightly by pushing the sliding block 461, so that the pressing roller 462 can drive the sealing film to move synchronously with the transport vehicle 1, thereby unfolding the folded sealing film.

[0059] In the fifth step, the transport vehicle 1 drives the grooving block 53 and the triangular block 531 to cut a groove on the inner wall of the sealing groove, and then the plugging wheel 58 pushes the sealing film into the groove cut on the sealing groove, and then presses and pulls the sealing film through the front side of the anti-slip block 54 to prevent the rotating plugging wheel 58 from pulling the sealing film out of the groove of the sealing groove.

[0060] In the sixth step, when the ramming piece 551 moves to the front, the coil spring pushes the ramming piece 551 forward, so that the ramming piece 551 rams the sealing film, making the sealing film and the groove wall of the sealing groove fit more closely, and the pushing plate 562 pushes the sealing film to the inside of the groove cut by the triangular block 531, thereby increasing the contact area between the sealing film and the sealing groove, thereby increasing the airtightness of the sealing film.

[0061] In the seventh step, the slurry storage tank 2 pours the clay slurry into the interior of the No. 1 pipe 571 and the No. 2 pipe 572 respectively, so that the No. 1 pipe 571 directly pours the clay slurry into the interior of the groove on the sealing groove, thereby sealing the sealing film inside the groove of the sealing groove wall, and at the same time, the No. 2 pipe 572 directly pours the clay slurry into the interior of the sealing groove, so that the sealing film is sealed inside the sealing groove.

[0062] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention and they are still covered by the protection scope of the present invention.
