Description

TECHNICAL FIELD

[0001] The present application relates to the field of underground continuous wall construction, in particular to an integrated channel type cutter and pile press assembly type ground wall construction equipment. BACKGROUND

[0002] The current underground continuous wall is widely used as a retaining wall and a water-stopping curtain. The TRD method is a current underground continuous wall construction technology, which uses a TRD method machine (i.e., a channel type cutter) to insert a cutting box with a cutting chain and a cutter head into the ground, while performing longitudinal cutting and horizontal pushing to form a groove, and injecting cement slurry into the foundation to achieve sufficient mixing and stirring with the original foundation to form an equal-thickness continuous wall underground.

[0003] Further, in order to improve the bearing capacity of the underground continuous wall, the assembly type ground wall (i.e., the assembly type underground continuous wall) is currently used, which includes underground continuous wall construction and pile pressing construction. The underground continuous wall is constructed using the TRD method machine, and the pile pressing construction is constructed using the pile press (the pile pressing construction refers to the use of the pile press to insert the precast pile into the underground continuous wall to form the assembly type underground continuous wall). Thus, the current assembly type underground continuous wall often needs to use the TRD method machine and the pile press simultaneously during construction. Since the TRD method machine and the pile press both need to use a large counterweight, the manufacturing cost is high; and the volume is large, which occupies a large area during construction, which makes the TRD method machine need to construct a long underground continuous wall during the construction of the assembly type underground continuous wall. After the TRD method machine travels a certain distance along the underground continuous wall, the pile press can enter the specified position for pile pressing construction, which leads to the fact that the pile pressing construction cannot be constructed in time, the construction steps are not compact, and the construction efficiency of the assembly type underground continuous wall is affected. SUMMARY

[0004] The purpose of the present application is to provide an integrated channel type cutter and pile press assembly type ground wall construction equipment, which integrates the pile press and the TRD method machine, simplifies the construction equipment of the assembly type ground wall, improves the structural compactness of the construction equipment, reduces the manufacturing cost of the construction equipment, and improves the compactness of the assembly type ground wall construction steps, thereby improving the construction efficiency of the assembly type underground continuous wall.

[0005] The technical solution of the present application is:

[0006] An integrated channel type cutter and pile press assembly type ground wall construction equipment, comprising a channel type cutter and a pile press, the channel type cutter comprising a cutter frame and a cutting box body transverse track arranged on the cutter frame, and the pile press comprising:

[0007] The pile press frame is fixed on the cutting machine frame, and a sheet pile transverse track parallel to the cutting box transverse track is arranged on the pile press frame.

[0008] The transverse support moves along the sheet pile transverse track, and a vertical track is arranged on the transverse support.

[0009] The lifting support moves along the vertical track.

[0010] The lifting support driving mechanism drives the lifting support to move along the vertical track.

[0011] The sheet pile clamping and fixing device is arranged on the lifting support and is used for clamping and fixing the sheet pile to be pressed.

[0012] As an optimization, the pile press further comprises an angle adjusting and driving device, and the sheet pile transverse track comprises:

[0013] The lower track is provided with a lower sliding seat.

[0014] The upper track is provided with an upper sliding seat, and the upper sliding seat is provided with an upwardly protruding jacking arc surface.

[0015] The lower part of the transverse support is rotationally connected to the lower sliding seat through a lower shaft, and the upper part of the transverse support is rotationally connected to the upper sliding seat through an upper shaft.

[0016] The angle adjusting and driving device comprises:

[0017] The lower oil cylinder drives the lower sliding seat to move along the lower track.

[0018] The upper oil cylinder is hingedly connected to the pile press frame at one end and is hingedly connected to the upper sliding seat at the other end.

[0019] Due to uneven construction ground, the plate pile to be pressed needs to be adjusted in angle; or some special construction conditions need to adjust the plate pile to be pressed to have a certain inclination angle; the scheme adds an angle adjustment and driving device, which integrates the "horizontal movement driving mechanism for driving the horizontal movement support to move along the plate pile horizontal movement track" and the "plate pile angle adjustment mechanism", so that the horizontal movement driving mechanism and the plate pile angle adjustment mechanism share the driving mechanism (share the lower oil cylinder and the upper oil cylinder), share the sliding mechanism (upper and lower tracks and upper and lower sliding seats), thereby realizing the original functions of the horizontal movement driving mechanism and the plate pile angle adjustment mechanism while effectively simplifying the horizontal movement driving mechanism and the plate pile angle adjustment mechanism. More importantly, the setting of the supporting arc surface on the upper sliding seat not only enables the plate pile angle adjustment of the integrated horizontal movement driving mechanism and plate pile angle adjustment mechanism to be smoothly realized, but also ensures that the horizontal movement support does not float upward during the pile pressing construction process of the pile press, ensuring the stable insertion of the prefabricated plate pile into the underground continuous wall.

[0020] As a preferred, the upper sliding seat is provided with an upper sliding groove with an upward opening, and the upper track is located in the upper sliding groove, and the supporting arc surface constitutes the inner bottom surface of the upper sliding groove. In this way, through the cooperation of the upper sliding groove and the upper track, the stable sliding of the upper sliding seat along the upper track is ensured; at the same time, the stable rolling of the supporting arc surface along the upper track is ensured.

[0021] As a preferred, the lower sliding seat is provided with a lower sliding groove with a downward opening, and the lower track is located in the lower sliding groove, and the inner top surface of the lower sliding groove is supported on the lower track. In this way, through the cooperation of the lower sliding groove and the lower track, the stable sliding of the lower sliding seat along the lower track is ensured.

[0022] As a preferred, the plate pile horizontal movement track and the cutting box body horizontal movement track are on the same straight line, and the horizontal movement support can be moved from the plate pile horizontal movement track to the cutting box body horizontal movement track. In this way, the horizontal movement support of the pile press can use the cutting box body horizontal movement track of the channel type cutting machine, thereby shortening the length of the plate pile horizontal movement track and reducing the volume of the pile press, which is conducive to further reducing the equipment volume.

[0023] As preferred, the pile press further comprises a sheet pile anti-settling clamping device for clamping the sheet pile, which is arranged on the transverse support and below the sheet pile clamping and fixing device. When the depth of the underground continuous wall is deep, the prefabricated sheet pile is generally composed of multiple segments spliced from bottom to top. During the pile pressing construction, when the next segment of the prefabricated sheet pile is pressed into place, the previous segment of the prefabricated sheet pile needs to be lifted above the next segment of the prefabricated sheet pile and connected to the next segment of the prefabricated sheet pile through a splicing structure, and then the previous segment of the prefabricated sheet pile is pressed downward by the pile press. However, in actual construction, since the prefabricated sheet pile is inserted into the underground continuous wall before it solidifies, the resistance on the prefabricated sheet pile is relatively small. When the next segment of the prefabricated sheet pile is pressed into place, the segment of the prefabricated sheet pile is prone to falling downward under the action of gravity and sinking into the underground cement soil continuous wall, which prevents the splicing of the previous segment of the prefabricated sheet pile and affects the construction quality of the underground cement soil continuous wall. In order to solve this problem, the sheet pile anti-settling clamping device is arranged. After a segment of the prefabricated sheet pile is pressed into place, the prefabricated sheet pile is clamped by the sheet pile anti-settling clamping device to splice the adjacent two segments of the prefabricated sheet pile, thereby preventing the prefabricated sheet pile from sinking downward under the action of gravity.

[0024] As preferred, the sheet pile anti-settling clamping device comprises:

[0025] The clamping support is fixed on the transverse support, and the clamping support has a sheet pile passing opening.

[0026] The anti-settling clamping mechanism comprises an anti-settling clamping oil cylinder arranged on the clamping support. In this way, without affecting the pressing construction of the prefabricated sheet pile, the prefabricated sheet pile can be clamped by the sheet pile anti-settling clamping device after a segment of the prefabricated sheet pile is pressed into place, thereby preventing the prefabricated sheet pile from sinking downward under the action of gravity.

[0027] As preferred, the sheet pile clamping and fixing device comprises:

[0028] The upper and lower clamping frames are arranged on the lifting support, and each of the upper and lower clamping frames is provided with a sheet pile accommodating opening.

[0029] The pressing clamping mechanism corresponds to the clamping frame one by one and is used for clamping and fixing the sheet pile on the clamping frame. In this way, the prefabricated sheet pile is fixed by the upper and lower clamping frames and the pressing mechanism, thereby ensuring the stable and reliable fixation of the prefabricated sheet pile.

[0030] As preferred, the pressing clamping mechanism comprises a front clamping oil cylinder and a rear clamping oil cylinder, which are located on the front and rear sides of the sheet pile accommodating opening. In this way, on the one hand, the prefabricated sheet pile can be clamped and fixed by the front clamping oil cylinder and the rear clamping oil cylinder, and on the other hand, the angle of the prefabricated sheet pile in the front-rear direction of the pile press can be adjusted by the front clamping oil cylinder and the rear clamping oil cylinder.

[0031] As preferred, the lifting support driving mechanism comprises a lifting oil cylinder, the upper end of which is connected with the top of the transverse support, and the lower end of which is connected with the lifting support.

[0032] The integrated channel type cutting machine and pile press of the assembly type diaphragm wall construction equipment integrates the pile press and the TRD method machine, which not only simplifies the construction equipment of the assembly type diaphragm wall, improves the structural compactness of the construction equipment, and reduces the manufacturing cost of the construction equipment, but also improves the compactness of the assembly type diaphragm wall construction steps, and further improves the construction efficiency of the assembly type diaphragm wall.

[0056] The present application will be further described in detail below in combination with the drawings and specific embodiments:

[0057] Specific embodiment one, as shown in Figure 1 , Figure 2 A fabricated ground wall construction equipment integrating a trench cutting machine and a pile presser includes a trench cutting machine 1 (i.e. a TRD method machine) and a pile presser 2. The trench cutting machine 1 includes a cutting machine frame 1.1 and a cutting box transverse track 1.2 arranged on the cutting machine frame. The cutting box of the trench cutting machine moves along the cutting box transverse track. The pile presser 2 includes a pile presser frame 3, a transverse support 5, a lifting support 6, a lifting support driving mechanism and a sheet pile clamping and fixing device. The pile presser frame is fixed on the cutting machine frame. In this embodiment, the pile presser frame is fixed on the cutting machine frame by bolts or welding. The pile presser frame is provided with a sheet pile transverse track 4 parallel to the cutting box transverse track. The transverse support moves along the sheet pile transverse track. The transverse support is provided with a vertical track. The lifting support lifts along the vertical track. The lifting support driving mechanism is arranged on the transverse support and drives the lifting support to lift along the vertical track. The sheet pile clamping and fixing device is arranged on the lifting support and is used to clamp and fix the sheet pile to be pressed and assembled.

[0058] In this embodiment, the pile presser is integrated into the trench cutting machine (i.e. a TRD method machine), so that the pile presser can share the walking equipment and counterweight equipment of the trench cutting machine, thereby simplifying the fabricated ground wall construction equipment, improving the compactness of the equipment structure and reducing the manufacturing cost of the construction equipment. More importantly, in the process of constructing the underground continuous wall by the trench cutting machine, the pile presser can timely perform pile pressing construction to insert the prefabricated sheet pile into the underground continuous wall to form a fabricated underground continuous wall, thereby improving the compactness of the fabricated ground wall construction steps and further improving the construction efficiency of the fabricated underground continuous wall.

[0059] Specifically, as shown in Figure 2 The lifting support driving mechanism includes lifting oil cylinders 7, the upper ends of which are connected with the top of the transverse support, and the lower ends of which are connected with the lifting support. In this embodiment, there are two lifting oil cylinders, which are distributed on the left and right sides of the lifting support.

[0060] As shown in Figure 2 , Figure 3 The sheet pile clamping and fixing device includes two clamping frames 8 and pressing clamping mechanisms 9. The two clamping frames are arranged on the lifting support, one of which is located at the upper part of the lifting support, and the other of which is located at the lower part of the lifting support. The two clamping frames are each provided with a sheet pile accommodating port 10. The pressing clamping mechanisms correspond to the clamping frames one by one, and are used to clamp and fix the sheet piles on the clamping frames. In this way, the prefabricated sheet piles are fixed by the two clamping frames and the pressing mechanisms, so as to ensure the stable and reliable fixation of the prefabricated sheet piles.

[0061] The pressing clamping mechanism includes front clamping oil cylinders 9.1 and rear clamping oil cylinders 9.2, which are distributed in the front-rear direction of the pressing machine. The front clamping oil cylinders and the rear clamping oil cylinders are located on the front and rear sides of the sheet pile accommodating port, i.e. the front clamping oil cylinders are located on the front side of the sheet pile accommodating port, and the rear clamping oil cylinders are located on the rear side of the sheet pile accommodating port. In this embodiment, there are two front clamping oil cylinders and two rear clamping oil cylinders in the same pressing clamping mechanism, and the two front clamping oil cylinders are located at the same height, and the two rear clamping oil cylinders are located at the same height. In this way, on the one hand, the prefabricated sheet piles can be clamped and fixed by the front clamping oil cylinders and the rear clamping oil cylinders, and on the other hand, the angle of the prefabricated sheet piles in the front-rear direction of the pressing machine can be adjusted by the front clamping oil cylinders and the rear clamping oil cylinders.

[0062] In actual construction, the prefabricated sheet piles (the sheet piles in the text are prefabricated sheet piles) are inserted into the sheet pile accommodating ports of the two clamping frames, and the prefabricated sheet piles are clamped and fixed by the pressing mechanisms on the two clamping frames. Then, the lifting support driving mechanism drives the lifting support and the prefabricated sheet piles clamped and fixed on the two clamping frames to descend along the vertical track, so as to insert the prefabricated sheet piles into the underground continuous wall.

[0063] Further, as shown in Figure 2 The clamping frame 8 is composed of a fixed half frame 8.1 and a movable half frame 8.2, the fixed half frame is fixed on the lifting support, and the movable half frame is hingedly connected with the fixed half frame. The sheet pile accommodating port is located between the fixed half frame and the movable half frame. In this way, in actual construction, the movable half frame can be opened by rotating around the hinge, and then the prefabricated sheet piles can be moved into the fixed half frame by the crane, and then the movable half frame can be closed by rotating around the hinge, so as to facilitate the hoisting of the prefabricated sheet piles into the vertical overpass of the concrete sheet piles of the two clamping frames in actual construction.

[0064] The movable half frame of the upper and lower clamping frames is connected by a vertical connecting rod. One of the clamping frames is further provided with a driving oil cylinder, one end of the driving oil cylinder is hingedly connected to the fixed half frame of the clamping frame, and the other end of the driving oil cylinder is hingedly connected to the movable half frame of the clamping frame. In this way, the movable half frames of the upper and lower clamping frames can be simultaneously controlled to rotate around the hinge to open or close by one driving oil cylinder. In the embodiment, the fixed half frame and the movable half frame on the same clamping frame are further provided with a locking mechanism, which is a manual locking mechanism or an automatic locking mechanism. When the movable half frame is driven by the driving oil cylinder to rotate around the hinge to close, the movable half frame is locked on the corresponding fixed half frame by the locking mechanism, so as to avoid the movable half frame from rotating around the hinge to open. When it is necessary to open the movable half frame, the locking mechanism is unlocked, so that the driving oil cylinder drives the movable half frame to rotate around the hinge to open. The locking mechanism is a prior art, and its specific structure is not the point of the present application. Therefore, the specific structure of the locking mechanism and other conventional technical means will not be described herein.

[0065] Further, as shown in Figure 2 、 Figure 3 、 Figure 4 The pile driver further comprises an angle adjusting and driving device. The sheet pile transverse moving track 4 comprises a lower track 4.2 and an upper track 4.1. The lower track is parallel to the upper track. The upper track is located above the lower track. The lower track is provided with a lower sliding seat 12. Specifically, the lower sliding seat is provided with a lower sliding groove with an opening facing downward, and the lower track is located in the lower sliding groove. The inner top surface of the lower sliding groove is a plane and supports the lower track. The upper track is provided with an upper sliding seat 11. The upper sliding seat is provided with a top supporting arc surface 18 protruding upward, which is located below the upper track and abuts against the upper track. Specifically, the upper sliding seat is provided with an upper sliding groove with an opening facing upward, and the upper track is located in the upper sliding groove. The top supporting arc surface constitutes the inner bottom surface of the upper sliding groove.

[0066] The lower part of the transverse moving support 8 is rotationally connected to the lower sliding seat through a lower shaft 17, and the upper part of the transverse moving support is rotationally connected to the upper sliding seat through an upper shaft 16. The lower shaft is parallel to the upper shaft. The lower shaft is perpendicular to the lower track. In the embodiment, the lower shaft is horizontally distributed. The axis of the top supporting arc surface 18 is parallel to the upper shaft, and the top supporting arc surface can roll along the upper track 4.1.

[0067] The angle adjusting and driving device comprises a lower oil cylinder 13 and an upper oil cylinder 14. The lower oil cylinder drives the lower sliding seat to move along the lower track. In the embodiment, one end of the lower oil cylinder is hingedly connected to the frame of the pile driver, and the other end of the lower oil cylinder is hingedly connected to the upper sliding seat. One end of the upper oil cylinder is hingedly connected to the frame of the pile driver, and the other end of the upper oil cylinder is hingedly connected to the upper sliding seat.

[0068] Due to uneven construction ground, the plate pile to be pressed is inclined, and the angle of the plate pile needs to be adjusted; or some special construction conditions, the plate pile to be pressed needs to be adjusted to have a certain inclination angle. The embodiment adds an angle adjustment and driving device, which integrates the "horizontal movement driving mechanism for driving the horizontal movement support to move along the plate pile horizontal movement track" and the "plate pile angle adjustment mechanism" into one, so that the horizontal movement driving mechanism and the plate pile angle adjustment mechanism share the driving mechanism (share the lower oil cylinder and the upper oil cylinder), share the sliding mechanism (upper and lower tracks and upper and lower sliding seats), thereby realizing the original functions of the horizontal movement driving mechanism and the plate pile angle adjustment mechanism while effectively simplifying the horizontal movement driving mechanism and the plate pile angle adjustment mechanism. More importantly, the setting of the top support arc surface on the upper sliding seat not only enables the plate pile angle adjustment of the integrated horizontal movement driving mechanism and plate pile angle adjustment mechanism to be smoothly realized, but also ensures that the horizontal movement support does not float upward during the pile pressing construction process of the pile press, ensuring the stable insertion of the prefabricated plate pile into the underground continuous wall.

[0069] The plate pile angle adjustment is as follows: the lower oil cylinder and the upper oil cylinder are moved asynchronously (i.e., at least one of the moving direction and the moving speed is different, such as the moving direction of the lower oil cylinder and the upper oil cylinder is different, or the moving speed of the lower oil cylinder and the upper oil cylinder is different, or neither the moving direction nor the moving speed is the same), to adjust the angle of the plate pile. For example, the lower oil cylinder is not working, and the piston rod of the upper oil cylinder is extended or retracted, then the plate pile will be adjusted as follows: due to the weight of the horizontal movement support, the lifting support, the plate pile clamping and fixing device and the plate pile supported on the lower track through the lower sliding seat, and due to the top support arc surface located below the upper track and resting on the upper track, the axis of the support arc surface is parallel to the upper shaft, and the top support arc surface can roll along the upper track; during this process, the upper sliding seat moves along the upper track, and the upper sliding seat also rolls along the upper track through the support arc surface, so that the upper sliding seat and the upper shaft rotate, to smoothly adjust the angle of the plate pile; and during the pile pressing construction process of the pile press, since the top support arc surface is located below the upper track and rests on the upper track, the horizontal movement support is prevented from floating upward, ensuring the stable insertion of the prefabricated plate pile into the underground continuous wall.

[0070] The horizontal movement of the horizontal movement support along the plate pile horizontal movement track is as follows: the lower oil cylinder and the upper oil cylinder move synchronously (i.e., the moving direction and the moving speed are the same), to realize the translation of the horizontal movement support along the plate pile horizontal movement track, to drive the horizontal movement of the horizontal movement support along the plate pile horizontal movement track. In actual construction, the angle of the plate pile is first adjusted, and then the horizontal movement support and the plate pile are moved to the position along the plate pile horizontal movement track; then the lifting support driving mechanism drives the lifting support and the prefabricated plate pile to descend along the vertical track together, to insert the prefabricated plate pile into the underground continuous wall.

[0071] Further, as Figure 1As shown, the sheet pile transverse moving track and the cutting box transverse moving track are in the same straight line, and the transverse moving support can be moved from the sheet pile transverse moving track to the cutting box transverse moving track. In this embodiment, the cutting box transverse moving track 1.2 includes two upper and lower guide rails 1.21, and the upper guide rail of the cutting box transverse moving track is in the same straight line with the upper rail, and the lower guide rail of the cutting box transverse moving track is in the same straight line with the lower rail. In this way, the transverse moving support of the pile press can use the cutting box transverse moving track of the channel type cutting machine, thereby shortening the length of the sheet pile transverse moving track and reducing the volume of the pile press, which is conducive to further reducing the volume of the equipment.

[0072] Further, as shown in Figure 2 , Figure 3 , the pile press further includes a sheet pile anti-settling clamping device 15. The sheet pile anti-settling clamping device is used to clamp the sheet pile. The sheet pile anti-settling clamping device is arranged on the transverse moving support and below the sheet pile clamping and fixing device. When the depth of the underground continuous wall is deep, the prefabricated sheet pile is generally composed of multiple segments spliced from bottom to top. During the pile pressing construction, when the next segment of the prefabricated sheet pile is pressed into place, the previous segment of the prefabricated sheet pile needs to be lifted above the next segment of the prefabricated sheet pile and connected to the next segment of the prefabricated sheet pile through a splicing structure, and then the previous segment of the prefabricated sheet pile is pressed downward by the pile press. However, in actual construction, since the prefabricated sheet pile is inserted into the underground continuous wall before it solidifies, the resistance experienced by the prefabricated sheet pile is relatively small. When the next segment of the prefabricated sheet pile is pressed into place, the segment of the prefabricated sheet pile is prone to falling downward and sinking into the underground cement soil continuous wall under the action of its own weight, which prevents the splicing of the previous segment of the prefabricated sheet pile and affects the construction quality of the underground cement soil continuous wall. To solve this problem, the present scheme provides a sheet pile anti-settling clamping device. After a certain segment of the prefabricated sheet pile is pressed into place, the sheet pile anti-settling clamping device clamps the prefabricated sheet pile to facilitate the splicing of the adjacent two segments of the prefabricated sheet pile, thereby preventing the prefabricated sheet pile from sinking downward under the action of its own weight.

[0073] As shown in Figure 2 , Figure 3 , the sheet pile anti-settling clamping device 15 includes a clamping support 15.1 and an anti-settling clamping mechanism. The clamping support is fixed on the transverse moving support and located at the bottom of the transverse moving support. The clamping support has a sheet pile passing opening 15.2. The sheet pile passing opening is located directly below the sheet pile receiving opening. The anti-settling clamping mechanism includes an anti-settling clamping oil cylinder 15.3 arranged on the clamping support. In this embodiment, there are four anti-settling clamping oil cylinders, two of which are distributed on the front side of the sheet pile passing opening, and the other two are distributed on the rear side of the sheet pile passing opening. In this way, without affecting the pressing construction of the prefabricated sheet pile, the sheet pile anti-settling clamping device can clamp the prefabricated sheet pile after a certain segment of the prefabricated sheet pile is pressed into place, thereby preventing the prefabricated sheet pile from sinking downward under the action of its own weight.

[0074] The above is only the preferred embodiment of the present application, and does not limit the present application, and any simple modification, change and equivalent transformation of the above embodiment according to the technical essence of the present application still belongs to the protection scope of the technical scheme of the present application.
