Description

Technical Field

[0001] This utility model relates to a boat with a plastic drainage board for water. Background Technology

[0002] The plastic sheet drainage method, used for soft soil foundation treatment, involves inserting strip-shaped plastic drainage sheets into the soft soil using a sheet-inserting machine, followed by surcharge preloading (or vacuum preloading). The pore water in the soft soil escapes through the channels in the plastic drainage sheets, thus consolidating the soft foundation and increasing its strength. A known sheet-inserting machine consists of a main trolley and a trolley. The trolley includes the inserter, vibratory hammer, main frame, and main winch. The main trolley is located on and can move along the rails, while the trolley is located on and can move along the main trolley. Originally designed for land use, this machine is used on water, placed on a simple pontoon for shipboard operations. During operation, the floating hull sways under the influence of waves, resulting in poor stability of the sheet-inserting machine. This not only leads to difficulty in positioning and inaccurate pile placement, resulting in low efficiency and difficulty in controlling project quality, but also poses significant safety hazards, with a high risk of capsizing accidents, especially in strong winds. To improve stability, the hull needs to be very large (over 2,000 tons), making the equipment investment for this project extremely expensive.

[0003] Additionally, current insertion machines are equipped with insertion tube a, the lower end of which is designed with a wedge shape. A tube shoe c is fastened to the tube wall with a metal chain d. A plastic drainage plate b passes through the lower end of insertion tube a from the upper end. The main function of the tube shoe c is to anchor the plastic drainage plate b to the lower end of insertion tube a, preventing sludge from entering the insertion tube a and sticking to the plastic drainage plate b, thus avoiding it being pulled out during tube removal (see...). Figure 1 In a traditional pipe shoe (c), the lower part of the plastic drainage board (b) is bent 180° and anchored to the outer diameter of the pipe shoe (c), with the surface of the plastic drainage board (b) protruding beyond the outer diameter of the pipe shoe (c). This structure has the following drawbacks: 1. The lower end of the insertion pipe (a) is not tightly sealed, making it easy for mud to enter; when pulling back the insertion pipe (a), the plastic drainage board (b) is easily pulled out; 2. When the insertion pipe (a) is inserted under the vibration force of the vibratory hammer, the force point at its lower end is the surface of the plastic drainage board (b) protruding beyond the outer diameter of the pipe shoe (c). If a hard block in the soil is encountered during the installation process, the plastic drainage board (b) is likely to break, causing the anchoring to fail. When pulling back the insertion pipe (a), the plastic drainage board (b) will be pulled back. Utility Model Content

[0004] The purpose of this invention is to overcome the defects of the prior art and provide a boat for inserting plastic drainage boards on water. It can meet the requirements of inserting plastic drainage boards to a depth of more than 40 meters and reduce the possibility of plastic drainage boards being pulled back.

[0005] The purpose of this utility model is achieved as follows: a floating plastic drainage board driving boat includes a hull, a pile frame moving track, a pile frame, a vibratory hammer, two insertion pipes, two pipe shoe openings, and two pipe shoes; wherein,

[0006] The hull includes a bow float, a stern float, and a pair of hull beams connecting the two sides of the bow float and the two sides of the stern float, so that the drainage plate opening is reserved in the middle of the hull;

[0007] The piling frame moving track includes longitudinal tracks fixed one-to-one on the top surface of a pair of side beams and a pair of transverse tracks, each installed at intervals on the pair of longitudinal tracks by bottom rollers.

[0008] The pile frame is fixed on a pile frame support plate, and a set of pile frame rollers are fixed on the bottom surface of the front end and the bottom surface of the rear end of the pile frame support plate, so that the pile frame is installed on a pair of transverse tracks through the two sets of pile frame rollers on the pile frame support plate;

[0009] The vibratory hammer is suspended from the front end face of the pile frame by pulleys mounted on top of the pile frame and winches mounted on the hull;

[0010] The top surfaces of the two insertion tubes are fixed to the bottom surface of the vibratory hammer by the insertion tube mounting plate; the insertion tube mounting plate has two rectangular drainage plate insertion holes that correspond one-to-one with the two insertion tubes, and each of the two insertion tubes has a drainage plate through hole that communicates one-to-one with the two drainage plate insertion holes and has the same shape as the drainage plate insertion holes.

[0011] Two boot openings are coaxially connected to the lower ends of two insertion tubes in a one-to-one correspondence; each boot opening is a rectangular tube with a cross-sectional length greater than its width and a width greater than the outer diameter of the insertion tube, and the inner hole of the boot opening is an inverted conical rectangular hole; a semi-circular boot groove is opened on the bottom surface of each boot opening, the central axis of the boot groove coincides with the center line of the length direction of the inner hole of the boot opening, and the radius of the boot groove is greater than half the width of the lower end of the inner hole of the boot opening;

[0012] Two tube shoes are installed one-to-one at the bottom of two tube shoe openings; each tube shoe includes a round steel bar, a hook, and a tube shoe chain; the radius of the round steel bar is adapted to the radius of the tube shoe groove on the bottom surface of the tube shoe opening, and the length of the round steel bar is greater than the cross-sectional length of the tube shoe opening; the hook is a horizontal U-shaped plate, which is fixed to the middle of the outer surface of the round steel bar; the tube shoe chain is connected between one end of the round steel bar and the lower outer surface of the tube.

[0013] First, insert the plastic drainage board through the inlet into the drainage board through hole and out through the lower end of the inner hole of the tube shoe opening. Then, roll the head of the plastic drainage board into a circle, insert the tube shoe hook into the head of the plastic drainage board, and then pull the plastic drainage board above the tube to make the tube shoe hook enter the inner hole of the tube shoe opening, and make the round steel embedded in the tube shoe groove on the bottom surface of the tube shoe opening, thus sealing the lower end of the inner hole of the tube shoe opening.

[0014] In the aforementioned floating plastic drainage board insertion boat, a pipe guide plate is fixed on the front end face of the pile frame support plate. Two guide holes are opened on the pipe guide plate so that two pipes are inserted into the two guide holes one-to-one.

[0015] The aforementioned floating plastic drainage board insertion boat further includes a water injection pipe connected to two water injection branch pipes, the other ends of which are connected to water injection holes opened on the upper part of the two insertion pipes in a corresponding manner.

[0016] The waterborne plastic drainage board of this utility model has the following characteristics:

[0017] 1. It can meet the requirements of driving plastic drainage boards to a depth of more than 40 meters, and the pile frame is relatively high, ensuring stability when installed and used on the hull;

[0018] 2. The insertion of the pipe is completed by using the excitation force of the vibratory hammer, which has the ability to penetrate the silt layer. The insertion speed is fast, and it only takes 3 minutes to insert a 40-meter-deep plastic drainage board.

[0019] 3. By installing a water injection pipe on the insertion pipe, the pressure at the pipe shoe opening can be increased, making it easier for the head of the plastic drainage board to remain in the silt, reducing the possibility of the plastic drainage board being pulled back, and also reducing the phenomenon of silt entering and clogging the pipe shoe opening.

[0020] 4. The pipe shoe is easier to install, has a more stable effect, and can be reused, reducing the cost of use. When the pipe is inserted into the silt, the pipe shoe opening is closed, and the head of the plastic drainage board is located inside the pipe shoe opening, which can prevent the head of the plastic drainage board from directly contacting the silt, thereby avoiding the plastic drainage board from being crushed. When the pipe is pulled out, the pipe shoe opening will automatically open, and the pipe shoe will be lifted along with the pipe through the pipe shoe chain, leaving the plastic drainage board in the silt.

[0028] The hull includes a bow float 11, a stern float 12, and a pair of beams 13 connecting the two sides of the bow float 11 and the two sides of the stern float 12, so that the hull has a pre-drainage plate opening in the middle.

[0029] The piling frame moving track includes longitudinal rails 21 fixed one-to-one on the top surface of a pair of side beams 13, and a pair of transverse rails 22 each mounted on the pair of longitudinal rails 21 at intervals via bottom rollers. The pair of transverse rails 22 move longitudinally along the pair of longitudinal rails 21 by means of a motor.

[0030] The pile frame 3 is a truss made of welded steel pipes and fixed on a pile frame support plate 30. The height of the pile frame 3 matches the insertion depth of the plastic drainage board. A set of pile frame rollers is fixed on the front and rear bottom surfaces of the pile frame support plate 30, so that the pile frame 3 is installed on a pair of transverse rails 22 through the two sets of pile frame rollers on the pile frame support plate 30. The pile frame support plate 30 moves longitudinally along the pair of transverse rails 22 by motor power. A pipe insertion guide plate 3A is fixed on the front surface of the pile frame support plate 30.

[0031] The vibratory hammer 4 is suspended on the front end face of the pile frame 3 by a pulley (not shown) mounted on the top of the pile frame 3 and a winch (not shown) mounted on the hull.

[0032] The outer surface of the insertion tube 5 is cylindrical. The top surfaces of the two insertion tubes 5 are fixed to the bottom surface of the vibratory hammer 4 through the insertion tube mounting plate (not shown in the figure). The two insertion tubes 5 are inserted into the two guide holes of the insertion tube guide plate 3A in a one-to-one correspondence. Two rectangular drainage plate insertion holes are opened on the insertion tube mounting plate, which correspond one-to-one with the two insertion tubes 5. A drainage plate through hole with the same shape as the drainage plate insertion holes is opened in each of the two insertion tubes 5.

[0033] Two boot openings 6 are coaxially connected to the lower ends of two insertion tubes 5 in a one-to-one correspondence; each boot opening 6 is a rectangular tube with a height of 70mm; the length of the cross-section of the boot opening 6 is greater than its width, and the width of the cross-section of the boot opening 6 is greater than the outer diameter of the insertion tube 5; the inner hole of the boot opening 6 is an inverted conical rectangular hole to increase the wall thickness at the lower end of the boot opening 6 and enhance the strength of the boot opening 6; a semi-circular boot groove is opened on the bottom surface of each boot opening 6, the central axis of the boot groove coincides with the center line of the length direction of the inner hole of the boot opening 6, and the radius of the boot groove is greater than half the width of the lower end of the inner hole of the boot opening 6;

[0034] Two water injection branch pipes are connected to the water injection pipe 7, and the other ends of the two water injection branch pipes are connected to the water injection holes opened on the upper part of the two insertion pipes 5 in a corresponding manner.

[0035] Two tube shoes are installed one-to-one at the bottom of two tube shoe openings 6; each tube shoe includes a round steel bar 81, a hook 82 and a tube shoe chain 80; the radius of the round steel bar 81 is adapted to the radius of the tube shoe groove on the bottom surface of the tube shoe opening 6, the length of the round steel bar 81 is greater than the cross-sectional length of the tube shoe opening 6, the hook 82 is a horizontal U-shaped plate, the thickness of the hook 82 is less than the diameter of the round steel bar 81, and the hook 82 is fixed to the middle of the outer surface of the round steel bar 81; the tube shoe chain 80 is connected between one end of the round steel bar 81 and the lower outer surface of the tube 5.

[0036] This utility model relates to a boat for inserting plastic drainage boards on water. When inserting the plastic drainage boards 9, the boat enters the construction area. First, two plastic drainage boards 9 are inserted one-to-one through the drainage board through holes in two insertion plates on the insertion pipe mounting plate into the drainage board through holes in two insertion pipes 5, and then one-to-one through the bottom surfaces of two pipe shoe openings 6. Next, the heads of the two plastic drainage boards 9 are rolled into loops, and the insertion hooks 82 of the two pipe shoes are inserted one-to-one into the heads of the two plastic drainage boards 9. Then, the two plastic drainage boards 9 are lifted from above the two insertion pipes 5, so that the insertion hooks 82 of the two pipe shoes enter the inner holes of the two pipe shoe openings 6, and the round steel 81 of the two pipe shoes is embedded one-to-one in the pipe shoe grooves on the bottom surfaces of the two pipe shoe openings 6, sealing the lower ends of the inner holes of the two pipe shoe openings 6. The winch is started to lower the vibratory hammer 4, and the excitation force of the vibratory hammer 4 simultaneously inserts the two insertion pipes 5 into the silt layer at a set depth. When the two insertion pipes 5 are pulled out, the vibratory hammer 4 and the two insertion pipes 5 are lifted by a winch. The two pipe shoes and the heads of the two plastic drainage boards 9 remain in the silt. After the two insertion pipes 5 are pulled out of the silt layer, the two pipe shoes are pulled by their corresponding pipe shoe chains 80 and disengage from the heads of the two plastic drainage boards 9 one by one. They are lifted together with the two insertion pipes 5, while the heads of the two plastic drainage boards 9 remain in place, thus completing the installation process of the two plastic drainage boards 9. During the process of pulling out the two insertion pipes 5, water is injected into the two insertion pipes 5 through the water injection pipe 7 to increase the pressure in the inner hole of the two pipe shoe openings 6, making it easier for the heads of the two plastic drainage boards 9 to remain in the silt, reducing the possibility of the two plastic drainage boards 9 being pulled back, and also reducing the phenomenon of mud entering and clogging the two pipe shoe openings 6. After the two plastic drainage boards 9 are installed, the next two plastic drainage boards 9 are installed by moving the pile frame support plate 30 laterally. After a row of horizontal plastic drainage boards is installed in a drainage board installation opening, the pair of horizontal rails 22 can be moved longitudinally to install the next row of horizontal plastic drainage boards.

Those skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and should be defined by the claims.
