DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0021] Embodiment one, a continuous wall TRD method wall forming machine with equal thickness, including box body 11, such as Figures 1-2The assembly groove is arranged on both sides of the box body 11, which can provide a working space for the chain 2 and the cutter 3. The number of the box bodies 11 is several, and the adjacent two box bodies 11 are movably connected, that is, the box body 11 is designed in a segmented splicing mode, and the number thereof is determined according to actual requirements to adapt to different depth requirements. An inclinometer is arranged on the box body 11 to monitor the perpendicularity in real time, so as to ensure the wall forming precision. An embedding groove is arranged at the top end of the box body 11, and an embedding block is fixedly connected to the bottom end of the box body 11. The embedding block on the upper box body 11 is movably clamped in the embedding groove on the lower box body 11, and the embedding block and the embedding groove are connected through the connecting bolt 12. The connection design of the embedding block and the embedding groove effectively ensures the stability of the connection of the two box bodies 11, and the connecting bolt 12 can realize the assembly and disassembly of the two box bodies 11, which is simple to operate. The box body 11 and the connecting bolt 12 are components of the cutting box 1 to cut the stratum soil.

[0022] As Figure 1 , the chain 2 is movably arranged in the assembly groove of the box body 11, thereby providing power for the moving cutter 3. As Figures 2-5 , the chain 2 comprises a shaft sleeve 21, a chain plate 22 and a chain pin 23. The number of the shaft sleeves 21 is several, and the several shaft sleeves 21 are linearly arranged. The chain plates 22 are arranged on both sides of the shaft sleeve 21, and one chain plate 22 is correspondingly arranged with two shaft sleeves 21. The upper half of the chain plate 22 is connected with one shaft sleeve 21 through the chain pin 23, and the lower half of the chain plate 22 is connected with another shaft sleeve 21 through the chain pin 23. The several shaft sleeves 21, the chain plates 22 and the chain pins 23 together constitute a complete chain 2 with the first end connected with the second end, so as to be conveniently driven by a chain wheel and drive the cutter 3 to move synchronously.

[0023] As Figure 1 , Figures 3-4 , the number of the cutters 3 is several, and the several cutters 3 are linearly arranged on the chain 2, so that the stratum can be longitudinally cut when the chain 2 drives the cutter 3 to move in rotation. It should be noted that the side of the chain 2 moving upward faces the stirred area, and the side moving downward faces the area of the uncut soil body, thereby forming a “scraping-pushing” action, and cooperating with the horizontal advancement of the cutting box 1 to effectively improve the stirring uniformity and enhance the construction safety. The cutter 3 comprises a connecting seat 31, a connecting plate 32, a limiting assembly 4 and a fixing assembly 5. As Figures 6-15The connecting seat 31 is fixedly connected with the connecting plate 32, the rear wall of the connecting seat 31 is in contact with the inner wall of the box body 11, that is, the connecting seat 31 is in contact with the wall surface of the box body 11 located in the assembly groove, the rear wall of the connecting plate 32 is in contact with the outer wall of the box body 11, that is, the connecting plate 32 is in contact with the wall surface of the box body 11 located outside the assembly groove, the connecting seat 31 and the connecting plate 32 are T-shaped in composition, and the connecting seat 31 and the connecting plate 32 are movably clamped with the side wall of the box body 11, so that the connecting seat 31 and the connecting plate 32 are stably arranged on the box body 11, and when the connecting seat 31 and the connecting plate 32 move, the connecting seat 31 can effectively clean the impurities attached in the assembly groove, and the connecting plate 32 can effectively clean the impurities attached to the side wall of the box body 11, so that the stable movement of the chain 2 and the cutter 3 is not affected, and the rear half of the connecting seat 31 is movably clamped with the middle part of the chain 2, so that the connecting seat 31 is flexibly connected with the chain 2.

[0024] As Figures 6-15 , the box body 11 is provided with a limiting groove, and the two sides of the connecting seat 31 are fixedly provided with a limiting assembly 4, and the limiting assembly 4 is movably clamped with the limiting groove, specifically, two limiting assemblies 4 are arranged in one cutter 3, and the front half of the connecting seat 31 is fixedly connected with the limiting assembly 4, which can help to enhance the connection relationship between the cutter 3 and the box body 11, the limiting assembly 4 comprises a limiting plate 41 and a limiting bolt 42, as Figures 6-7 , two limiting plates 41 are arranged in one limiting assembly 4, and the two limiting plates 41 are symmetrically arranged, the limiting groove of the box body 11 is arranged in the assembly cavity, and the limiting groove is in position correspondence with the limiting plate 41, and the two limiting plates 41 are movably clamped in the limiting groove of the box body 11, so that when the cutter 3 is subjected to a lateral force, the connecting seat 31 is connected with the box body 11 through the limiting plate 41, so that not only the force from front to back acting on the connecting seat 31 can be dispersed to the box body 11, but also the connecting seat 31 can be limited and fixed, avoiding excessive shaking of the connecting seat 31 and affecting the chain 2, for one limiting assembly 4, one limiting plate 41 is connected with the top end of the connecting seat 31 through the limiting bolt 42, and the other limiting plate 41 is connected with the bottom end of the connecting seat 31 through the limiting bolt 42, effectively ensuring the stability of the limiting plate 41 arranged on the connecting seat 31.

[0025] As Figures 6-15 , the box body 11 is provided with a fixed groove, and the rear two ends of the connecting plate 32 are fixedly provided with a fixed assembly 5, and the fixed assembly 5 is movably clamped with the fixed groove, specifically, two fixed assemblies 5 are arranged in one cutter 3, and the rear half of the connecting plate 32 is fixedly connected with the fixed assembly 5, which can help to enhance the connection relationship between the cutter 3 and the box body 11, the fixed assembly 5 comprises a fixed block 51 and a fixed bolt 52, as Figures 8-9The rear side of the connecting plate 32 is provided with a side groove, and the front end of the fixing block 51 is movably clamped in the side groove of the connecting plate 32. The fixing groove of the box body 11 is arranged outside the assembly cavity and corresponds to the position of the fixing block 51. The rear end of the fixing block 51 is movably clamped in the fixing groove of the box body 11. Therefore, when the cutter 3 is subjected to a lateral force, the connecting plate 32 is connected to the box body 11 through the fixing block 51, so that not only the force from the left and right directions received by the connecting plate 32 can be dispersed to the box body 11, but also the connecting plate 32 can be fixed and limited to avoid excessive shaking of the connecting plate 32 and affect the chain 2. It should be noted that the opening directions of the fixing groove and the limiting groove are different, and the two are arranged perpendicularly at 90 degrees. The cutter 3 can be limited from different directions to improve the stability of the cutter 3 when subjected to a lateral force. The fixing block 51 is connected to the connecting plate 32 through the fixing bolt 52, which effectively ensures the stability of the fixing block 51 arranged on the connecting plate 32.

[0026] The connection relationship of the cutter 3 is changed, the cutter 3 is limited and arranged in the box body 11 and is supported by the box body 11, so that the lateral force borne by the cutter 3 is dispersed to the box body 11, and the chain 2 only provides pulling force to drive the cutter 3 to move, without bearing external force caused by cutting of the cutter 3. The connection of the chain 2 is prevented from being broken and other faults to affect the operation of the whole chain 2, so as to prolong the service life of the chain 2.

[0027] In the embodiment two, on the basis of the embodiment one, as Figures 6-15 The cutter 3 further comprises a movable assembly 6. The box body 11 is provided with a movable groove, and the connecting plate 32 is provided with the movable assembly 6 which is movably clamped in the movable groove, for cutting soil blocks to improve the wall forming efficiency and effect. The movable assembly 6 comprises a movable plate 61, a movable bolt 62 and a movable block 63, as Figures 10-12The movable plate 61 is movably arranged on the front side of the connecting plate 32 and is located outside the box body 11, and the movable plate 61 directly faces the stratum soil to enhance the impact, crushing and stirring effect on the soil in the stratum. The front wall of the connecting plate 32 is a curved surface, and the movable plate 61 can rotate along the front wall of the connecting plate 32 to provide conditions for the swing of the movable plate 61. The front half of the connecting plate 32 movably sleeves the movable bolt 62, and the rear side of the connecting plate 32 is provided with a side hole located on one side of the side groove. The movable block 63 penetrates through the side hole of the connecting plate 32 and movably sleeves the movable bolt 62, so that the movable block 63 can be stably fixed on the connecting plate 32 by the movable bolt 62. The movable groove is arranged on one side of the fixed groove and corresponds to the position of the movable block 63. The front end of the movable block 63 is fixedly connected with the movable plate 61, and the rear end of the movable block 63 is movably connected with the movable groove. Therefore, when the cutter 3 is subjected to a lateral force, the connecting plate 32 is connected with the box body 11 through the movable block 63, so that not only the force from left and right directions acting on the movable assembly 6 and the connecting plate 32 can be dispersed to the box body 11, but also the movable assembly 6 and the connecting plate 32 can be limited and fixed, avoiding excessive shaking of the movable assembly 6 and the connecting plate 32 to affect the chain 2. It should be noted that the fixed groove and the movable groove have the same opening direction, so that the movable assembly 6 can assist the fixed assembly 5 to limit the cutter 3 to improve the stability of the cutter 3 under lateral force. Two movable blocks 63 are arranged in one movable assembly 6, and one movable block 63 corresponds to one fixed block 51. A plurality of through holes are arranged on the box body 11 between the fixed groove and the movable groove. The movable block 63 and the fixed block 51 have opposite magnetism, that is, the movable block 63 and the fixed block 51 have magnetic force of mutual attraction. Therefore, when the cutter 3 moves to the position of the through hole, the movable block 63 is driven upward by the magnetic force of the fixed block 51. When the cutter 3 moves to the position without the through hole, the movable block 63 is not affected by the magnetic force of the fixed block 51, so that the movable plate 61 swings downward due to gravity. In this way, the movable assembly 6 can swing back and forth when moving along the box body 11, so as to improve the crushing effect on the soil and enhance the mixing effect of the solution and the soil.

[0028] In example three, on the basis of example two, as Figure 2 The cutting box 1 further comprises a liquid injection assembly 7. Two liquid injection assemblies 7 are arranged in the box body 11 to provide two independent channels for the injection of solidification liquid and cutting liquid, so as to spray the solidification liquid and cutting liquid to a specific direction, thereby meeting the needs of different construction stages. Specifically, in the excavation stage, the liquid injection assembly 7 close to the uncut soil area sprays cutting liquid to play a lubricating and carrying role, thereby optimizing the soil removal efficiency and realizing the loosening of the soil and the return of the crushed soil to the ground. In the wall forming stage, the liquid injection assembly 7 close to the mixed area sprays solidification liquid to realize the efficient mixing of the solidification liquid and the soil, thereby forming a wall with certain strength. The liquid injection assembly 7 comprises a main pipeline 71 and an auxiliary pipeline 72.Figures 13-15 The box 11 is provided with a main pipeline 71, the box 11 is provided with an auxiliary pipeline 72, one end of the auxiliary pipeline 72 is fixedly communicated with the inside of the main pipeline 71, the other end of the auxiliary pipeline 72 is fixedly communicated with the assembly groove, the number of the auxiliary pipeline 72 is several, and the several auxiliary pipelines 72 are linearly arranged along the main pipeline 71; in working, the solution is discharged to the assembly groove through the main pipeline 71 and the auxiliary pipeline 72, and finally is discharged to the outside of the box 11 to mix with the soil block; the thickness of the connecting seat 31 is larger than the diameter of the auxiliary pipeline 72, so that the connecting seat 31 can close the auxiliary pipeline 72 when moving to the auxiliary pipeline 72, so that when the solution is sprayed in the liquid injection assembly 7, the movement of the connecting seat 31 can intermittently close a part of the auxiliary pipeline 72, so as to instantaneously increase the outward impact force of the other part of the auxiliary pipeline 72 for spraying the solution, thereby effectively enhancing the cleaning effect on the cutter 3, and effectively enhancing the impact, crushing and stirring effect on the soil block.

[0029] The working principle of the use method of the present application is as follows: In construction, the cutting box 1 is assembled according to the construction depth and geological conditions, and is vertically inserted into the stratum, then the cutting box 1 is driven to move horizontally, at the same time, the chain 2 is driven to drive the cutter 3 to move longitudinally, in this process, the limiting assembly 4 is movably clamped with the limiting groove, the fixing assembly 5 is movably clamped with the fixing groove, and the movable assembly 6 is movably clamped with the movable groove, so that the cutter 3 is supported and limited by the box 11, when the cutter 3 cuts the soil block of the stratum, the lateral force borne by the cutter 3 is effectively dispersed to the box 11, and the chain 2 only provides pulling force to drive the cutter 3 to move, without bearing the external force brought by the cutting of the cutter 3, thereby effectively preventing the connection of the chain 2 from being broken and other faults to affect the operation of the whole chain 2, so as to prolong the service life of the chain 2.

[0030] In the process that the chain 2 drives the cutter 3 to move, the connecting seat 31 moves along the assembly groove to effectively clean the impurities attached to the assembly groove, and the connecting plate 32 moves along the outer wall of the box 11 to effectively clean the impurities attached to the outer wall of the box 11, thereby avoiding affecting the stable movement of the chain 2 and the cutter 3.

[0031] At the same time, the movement of the cutter 3 will make the fixing assembly 5 and the movable assembly 6 intermittently encounter the through hole, if the cutter 3 moves to the position of the through hole, the movable block 63 is driven by the magnetic force of the fixed block 51 to make the movable plate 61 rise, if the cutter 3 moves to the position of the non-through hole, the movable block 63 is not affected by the magnetic force of the fixed block 51, so that the movable plate 61 is lowered due to its own gravity, so as to reciprocate, effectively promoting the reciprocating swing of the movable assembly 6, so as to improve the crushing effect on the soil block, thereby enhancing the mixing effect of the soil block and the solution.

[0032] When the construction is carried out, the liquid injection assembly 7 can spray different kinds of solution at different stages, and the sprayed solution can further clean the impurities on the connecting seat 31, thereby further improving the moving stability of the chain 2 and the cutter 3. In addition, the movement of the connecting seat 31 can intermittently close a part of the auxiliary pipeline 72, so as to instantaneously increase the outward impact force of the solution sprayed by the other part of the auxiliary pipeline 72. This can not only effectively enhance the cleaning effect on the cutter 3 and the impurities thereon, but also effectively enhance the impact, crushing and stirring effect on the soil outside the box body 11.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application.
