Description

Technical Field

[0001] The invention relates to a novel drainage board vacuum preloading geotextile construction equipment and a construction method thereof. Background Art

[0002] In recent years, governments at all levels in my country have attached increasing importance to environmental protection. Dredging and filling projects in rivers, lakes and offshore areas of major cities and mud treatment on construction sites have continued to develop rapidly. At present, construction piling mud must be treated before it can be transported. Therefore, the project needs to quickly and effectively treat the mud to reduce its water content, increase the strength of the soil, and facilitate transportation. The installation of vertical drainage boards combined with vacuum / loading preloading and accelerated soil drainage and consolidation is an economical and effective method to improve the strength of soft clay. The use of PVD to treat natural deep soft foundations has been widely and maturely applied in my country. However, sometimes restricted by external conditions, dedicated storage yards are often shallow. If PVD treatment is used, the treatment depth is very shallow and the plate depth is short, which in disguise reduces the construction efficiency and increases the construction cost. At the same time, for high-water content mud, its consolidation compression deformation is very large, resulting in serious bending and deformation of the PVD. At the same time, there are many clogging phenomena of vertical drainage boards, and the vacuum degree is continuously lost as the soil layer deepens, resulting in unsatisfactory reinforcement effect of deep soil, affecting the treatment effect and construction period, which is not conducive to the high turnover utilization of the yard and even affects urban area planning.

[0003] In order to solve these problems, horizontal drainage boards laid in strips and layers were introduced into the project. In the project, the horizontal drainage boards were laid in layers, which can achieve consolidation and drainage while pumping mud, which is simple to construct and saves energy; it avoids sharp bending of the board, ensures effective vacuum transmission, ensures treatment effect, saves construction time, and improves the turnover utilization rate of the yard. In addition, the research results show that the use of horizontal drainage board method can effectively increase the total amount of mud treatment, reduce uneven settlement, and improve the quality of the project. Although the horizontal drainage board has many excellent properties, there are still some defects in actual application, as follows:

[0004] There is still clogging. As the project progresses, the single horizontal drainage board will gradually become clogged, and the drainage effect becomes worse and worse, affecting the progress of the project.

[0005] The current processing of vacuum pre-pressed materials is all done manually, which leads to high engineering labor costs. The initial preparation cycle is long, and the manually processed products are not fine enough.

[0006] The layout of the horizontal drainage board-geotextile fabric on site currently relies solely on manpower, which is too slow and difficult to lay. Summary of the invention

[0007] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a new type of drainage board vacuum preloading geotextile construction equipment and a construction method thereof. The purpose is to solve the problem of easy clogging of the drainage board by wrapping a layer of geotextile on the periphery of the horizontal drainage board, and the geotextile has excellent water permeability, which prevents clogging while ensuring the normal drainage function of the drainage board. The material is produced in an automated processing manner, which reduces the participation of manpower and increases the application of modern machinery, which can effectively reduce labor costs and increase the processing rate. Mechanical processing can improve product refinement, achieve high-precision guiding, positioning, and adjustment, and greatly improve labor productivity.

The first conveying device is provided with a first conveyor belt 221, and the first placement trough 22 is fixedly connected to the first conveying device 21. A plurality of first support frames 23 are built on the first conveying device 21, and the first support frames 23 are also provided with a first electric hoist 11. The first support frames 23 are arranged in an array along the length direction of the first conveying device 21. The first support frames 23 are provided with a first manipulator 24, and the first manipulator 24 can slide back and forth along the extension direction of the first support frame 23.

[0039] The second equipment 3 includes a second transport device 31 and a second placement slot 32 for placing an external hand-shaped joint, a drain pipe and a ring buckle. The second transport device 31 is provided with a second transport belt 321. The second placement slot 32 is fixedly connected to the second transport device 31. A plurality of second support frames 33 are built on the second transport device 31. The plurality of second supports 33 are arranged in a staggered manner in the horizontal and vertical directions. The second support frame 33 is provided with a second manipulator 34 and a third manipulator 35, an automatic screw machine 36 and a binding machine 37. The second manipulator 34 is used to clamp the hand-shaped joint. The third manipulator 35 is used to insert the drain pipe into the hand-shaped joint. The third manipulator frame then inserts the ring buckle into the connection between the hand-shaped joint and the drain pipe. The automatic screw machine 36 screws the screw into the ring buckle to connect the hand-shaped joint with the drain pipe. The binding machine 37 is used to bind the drainage board 13 and the geotextile 12.

[0040] The third equipment 4 includes a third conveying device 41 and a third placement trough 42 for placing the geotextile 12, the third conveying device is provided with a third conveyor belt 43, the third placement trough 42 is fixedly connected to the third conveying device 41, a plurality of third support frames 44 are built on the third conveying device 41, the third support frames 44 are arranged in an array along the length direction of the third conveying device 41, and a fourth manipulator 45 is provided on the third support frame 44, the fourth manipulator 45 can slide back and forth along the extension direction of the third support frame 44, and the fourth manipulator 45 is used to lay the geotextile 12 above the drainage board 13;

[0041] The fourth equipment 5 includes a fourth conveyor belt 51, a rack 52 and a sewing device 53. The sewing device 53 is arranged on the rack 52. When the geotextile 12 and the drainage board 13 are conveyed to the fourth conveyor belt 51, the sewing device 53 sews the two layers of geotextile 12 together.

[0042] The above specific improvement is to make the following preparations before the machine is operated: 1. Prepare the materials, put the geotextile 12 into the designated geotextile 12 slot, put the drainage board 13, and all the parts into the designated slots. Ensure that the materials are complete and the operation will not be interrupted when the machine is running; 2. Check the equipment again, run the data encoded on the computer after it is correct, observe whether the running track of each device is accurate, and whether the mechanical gripper can accurately pick up the material and transport it to the designated location; 3. After everything is ready, start the equipment;

[0043] The first device 2, the second device 3, the third device 4 and the fourth device 5 are connected to form the entire assembly line. In the process of the entire assembly line, most of the construction steps are completed by machines, which greatly improves the production efficiency and frees the hands of the construction workers. The function of the first device 2 is to place the drainage board 13 on the geotextile 12, place the geotextile 12 on the first placement groove 22, and then hang it on the first conveying device 21 through the electric hoist 11, and then use the first manipulator 24 to place the drainage board 13 on the top of the geotextile 12, and then transfer it to the second device 3;

[0044] The function of the second equipment 3 is to install the components on the drainage board 13. First, the hand-shaped joint is manually sleeved on the drainage board 13, the second manipulator 34 grabs the hand-shaped joint, and the third manipulator 35 grabs the drainage pipe and inserts it into the hand-shaped joint. Then the third manipulator 35 grabs the ring buckle and sleeves the ring buckle on the connection between the hand-shaped joint and the drainage pipe. Then the automatic screw machine 36 is used to screw the screw into the ring buckle, and finally the geotextile 12 and the drainage board 13 are bound together by the binding machine 37. This is superior to the existing technology, greatly reduces manual participation, and saves time. Compared with manual processing, a lot of costs are reduced. In the past, pure manual processing, the ring was not fine enough and the position might be distorted. The mechanical screwing is tighter, so that the pipe and the hand-shaped joint are connected more tightly and not easy to leak. Manual sewing of the drainage board 13 may have local sewing that is not fine and tight enough, which will cause mud to directly enter the drainage board 13 from the pores during the vacuuming process, causing the drainage board 13 to be blocked. The mechanical sewing is carried out according to the set program, which is fine and precise, ensuring the overall vacuuming effect.

[0045] As an improved specific implementation method, a first sensor 25 is provided on the first conveyor belt, and the first sensor 25 is a timing sensor; a second sensor 38 is provided at the rear end of the second support frame 33, and the second sensor 38 is an infrared sensor, and the second sensor 38 is coupled to the second conveyor belt; a third sensor 46 is provided on the third support frame 44, and the third sensor 46 is a timing sensor, and the third sensor 46 is coupled to the third conveyor belt 43; a fourth sensor 54 is provided at the front end of the frame rod 52, and the fourth sensor 54 is a timing sensor.

[0046] The above-mentioned specific improvement is that the first sensor 25 is arranged on the first device 2. The first sensor 25 is a timing sensor. Before operation, a time threshold is set on the computer. When the time threshold is reached, the first device 2 is operated, and the geotextile 12 enters the second device 3. Since the hand-shaped joint needs to be manually installed in the second device 3, the time cannot be accurately controlled. Therefore, the sensor in the second device 3 should adopt an infrared sensor. When the binding machine 37 binds the geotextile 12 and the drainage board 13, the infrared sensor senses the binding machine 37, and drives the geotextile 12 and the drainage board 13 to move to the third device 4; the third sensor 46 is the same as the first sensor 25. The fourth device 5 mainly plays a role in sewing the geotextile 12. Before the equipment is operated, the action trajectory can be pre-set on the computer.

[0047] As an improved specific implementation, the first electric hoist 11 is provided with a hook 111 and a stretching rope 112 , the hook 111 is connected to the stretching rope 112 , and the first electric hoist 11 is also provided with a winding disk 113 , and the stretching rope 112 is wound around the winding disk 113 .

[0048] The above-mentioned specific improvement is that the hook 111 provided on the electric hoist 11 mainly serves to hook and lift the geotextile 12 and place it on the first conveyor belt. The winding drum 113 is provided to effectively store the stretch rope 112.

[0049] As an improved specific implementation, it also includes two hanging frames 6 and a connecting frame 61 arranged between the two hanging frames 6, the hanging frames 6 and the connecting frame 61 form a "["-shaped structure, and at least two second electric hoists 7 are arranged on the connecting frame 61, and the second electric hoists 7 are used to lay the geotextile 12 in the mud pool.

[0050] The above-mentioned specific improvement is that after the geotextile 12 is sewn and transported to the site, a hanging frame 6 and a connecting frame 61 are first built on both sides of the mud pool, and then the second electric hoist 7 is hung on the connecting frame 61. The second electric hoist 7 is controlled by remote control wireless long-distance control, and the drainage board 13-geotextile is tied at both ends of one side of the mud pool, and then slowly moved to the center of the mud pool and dropped into the pool, and finally the geotextile rope was untied from the second electric hoist 7 and tied to the fixed steel pipe around the mud pool.

[0051] A novel construction method of a vacuum preloading geotextile for drainage board 13 comprises the following steps:

[0052] Step 1: manually place the geotextile 12 in the first placement groove 22, the first electric hoist 11 moves along the first support frame 23 to the top of the first placement groove 22, the first electric hoist 11 descends to clamp the geotextile 12, the first electric hoist 11 rises and moves along the first support frame 23 to the position above the first conveyor belt, the first electric hoist 11 descends to place the geotextile 12 on the first conveyor belt, and then the drainage board 13 is clamped above the geotextile 12 by the first manipulator 24, and the first conveyor belt 221 rolls to allow the geotextile 12 and the drainage board 13 to enter the second equipment 3;

[0054] Step 3: manually place the geotextile 12 in the third placement groove 42, move the first electric hoist 11 along the third support frame 44 to the top of the third placement groove 42, the first electric hoist 11 descends to clamp the geotextile 12, the first electric hoist 11 rises and moves along the third support frame 44 to the position above the third conveyor belt, the first electric hoist 11 descends to place the geotextile 12 on the third conveyor belt, and then the drainage board 13 is clamped above the geotextile 12 by the third manipulator 35, and the third conveyor belt 43 rolls to make the drainage board 13 and the geotextile 12 on the upper and lower sides of the drainage board 13 enter the fourth equipment 5;

[0055] Step 4: When the geotextile 12 and the drainage board 13 enter the fourth device 5, the sewing devices 53 at both ends of the rack 52 sew the geotextile 12;
