Description

Technical Field

[0001] The present invention relates to a flat-bottomed boat and its construction method, specifically a flat-bottomed boat for laying a one-way grid geotextile mattress and its construction method. Background Art

[0002] Geotextile mattresses are widely used in fields such as waterway regulation, bank slope reinforcement, flood control and emergency rescue. Compared with traditional riprap reinforcement for protecting the toe of the bank, geotextile mattresses can significantly reduce the amount of stone used, enhance the riverbank's resistance to water flow scouring, and improve the structural stability of the bank protection project. Currently, geotextile mattresses are mainly based on geotextiles sewn with reinforcing belts, and ballast blocks are fixed on the reinforcing belts to form the structure of the geotextile mattress. Therefore, the reinforcing belt is the main load-bearing component of the geotextile mattress structure.

[0003] When constructing the sinking of the existing geotextile mattress structure, it is necessary to wind the geotextile sewn with reinforcing belts around the cloth cylinder in advance, and rely on the card row beam to stop the sliding of the geotextile mattress during the sinking construction. Therefore, the construction vessels for laying geotextile mattresses are often equipped with large-sized cloth cylinders and card row beams, with a high degree of ship specialization and high requirements for the entry of construction equipment. Summary of the Invention

[0004] Object of the Invention: In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a flat-bottomed boat for laying a one-way grid geotextile mattress that is simple and convenient and can realize functions such as towing, sinking, and stopping of the one-way grid geotextile mattress. The present invention also discloses a construction method for a flat-bottomed boat for laying a one-way grid geotextile mattress that has low requirements for the ship, occupies a small area, and reduces the construction cost of the geotextile mattress.

[0005] Technical Solution: A flat-bottomed boat for laying a one-way grid geotextile mattress according to the present invention includes a working platform and a controller. A row-pulling mechanism and a sinking flap are arranged on one side of the working platform close to the riverbank; a row-stopping insurance mechanism, a tying and row-stopping mechanism, and a geotextile storage bin are sequentially arranged on the surface of the working platform. A crane for lifting ballast blocks is arranged near the tying and row-stopping mechanism; an external grid storage cage for storing one-way grids is arranged on one side of the working platform close to the river channel; the controller is connected to the working platform and the crane.

[0006] Further, the row-stopping insurance mechanism includes a rotating shaft one with a lifting function and a row-stopping tooth one. The row-stopping teeth one are evenly spaced circumferentially along the rotating shaft one. The row-stopping teeth one are smooth claw-shaped steel teeth. The included angle between the row-stopping tooth one and its adjacent row-stopping tooth one does not exceed 10°, and the tooth tip spacing between adjacent row-stopping teeth one is 5-10 mm smaller than the transverse rib spacing of adjacent one-way grids.

[0007] Further, the tying and row-stopping mechanism includes a rotating shaft two with a lifting function and a row-stopping tooth two. The row-stopping teeth two are evenly spaced circumferentially along the rotating shaft two. The rotating shaft two is connected to the rotating shaft one through a synchronous belt and is linked through gear connection. The row-stopping teeth two are smooth claw-shaped steel teeth.

[0008] Furthermore, the sinking plate turning board is inclined with the working platform, and the included angle is adjustable. Sliding wheels are arranged at the bottom of the geotextile storage bin, which is beneficial for manually towing the geotextile to the knotting and stopping mechanism. The external hanging grid storage cage is a detachable hanging wire cage, and the external hanging grid storage cage is fixed on the side of the flat boat close to the river center through 3 hanging buckles. The widths of the geotextile storage bin and the external hanging grid storage cage along the river bank direction are equivalent to the width of the knotting and stopping mechanism.

[0009] Furthermore, the row pulling mechanism includes a towing support, a fixed pulley group, a steel wire cable and a row pulling beam. The fixed pulley group is arranged on the towing support, and the fixed pulley group is connected with the row pulling beam through the steel wire cable.

[0010] The construction method of the flat boat for laying the one-way grid flexible mattress includes the following steps:

[0011] Step 1, move the flat boat to the bank of the river where the flexible mattress is to be laid through the controller, and ensure that the position of the knotting and stopping mechanism along the river bank direction coincides with the position where the mattress is to be laid, and then fix the flat boat at this laying position;

[0012] Step 2, lower the sinking plate turning board to ensure that the sinking plate turning board is placed on the river bank;

[0013] Step 3, erect the towing support of the row pulling mechanism, loosen the steel wire cable through the controller, and tow the row pulling beam to the end of the side of the knotting and stopping mechanism close to the river bank;

[0014] Step 4, tow the end of the geotextile in the geotextile storage bin to the row pulling beam, tow the one-way grid in the external hanging grid storage cage to the row pulling beam, combine the geotextile and the one-way grid at the end, and fix each node at the end of the one-way grid to the row pulling beam through ropes;

[0015] Step 5, hoist the ballast blocks to the knotting and stopping mechanism through a crane, manually disperse the ballast blocks to the corresponding bin holes according to the designed ballast density, and fix the ballast blocks to the one-way grid and the geotextile at the grid nodes through binding bands to complete the assembly of the one-way grid flexible mattress;

[0016] Step 6, horizontally lower the towing support to the side of the river bank, tighten the steel wire cable for towing the row pulling beam through the motor, tow the row pulling beam and the head of the one-way grid flexible mattress to move towards the river bank until the head of the one-way grid flexible mattress is 2 - 3 m above the water line of the river bank;

[0017] Step 7, anchor the head of the one-way grid flexible mattress to the river bank through anchor rods and steel drills, separate the head of the one-way grid flexible mattress from the row pulling beam, erect the towing support and fix the row pulling beam;

[0018] Step 8: The controller controls the simultaneous lifting of the second rotating shaft in the binding and anti-dumping mechanism and the first rotating shaft in the anti-dumping insurance mechanism, locks the first rotating shaft and the second rotating shaft, and the first anti-dumping tooth and the second anti-dumping tooth synchronously suspend the transverse ribs of the one-way grille.

[0019] Step 9: After the controller translates the flat-bottomed boat 5 - 8 m along the vertical riverbank towards the center of the river, the flat-bottomed boat is fixed.

[0020] Step 10: Repeat Step 5. The controller simultaneously lowers the first rotating shaft and the second rotating shaft to release the suspension of the first anti-dumping tooth and the second anti-dumping tooth on the transverse ribs of the one-way grille, unlocks the first rotating shaft. Under the action of its own weight and the traction of the first anti-dumping tooth and the second anti-dumping tooth, the one-way grille soft mattress smoothly sinks through the sinking flap.

[0021] Step 11: When the one-way grille soft mattress moves to the end of the binding and anti-dumping mechanism near the riverbank, repeat Steps 8 - 10 to complete the laying of the one-way grille soft mattress.

[0022] Step 12: After laying to the designed length of the one-way grille soft mattress, cut the geotextile, stop binding the ballast blocks, and drive the one-way grille to smoothly slide down through the binding and anti-dumping mechanism and the anti-dumping insurance mechanism to complete the sinking of the tail of the one-way grille soft mattress.

[0023] Beneficial effects: Compared with the prior art, the present invention has the following significant features:

[0024] 1. The one-way grille soft mattress is assembled on the flat-bottomed boat. Compared with the existing mattress sinking process, it does not require construction workers to work in the water, improving the construction quality.

[0025] 2. The one-way grille soft mattress has high tensile strength and good integrity. The grille bears the load while the mattress does not. Compared with the existing concrete block soft mattress, it is not easy to tear the mattress, ensuring the quality of mattress sinking.

[0026] 3. The one-way grille soft mattress has high durability. Compared with the existing hinge mattress, it is not easy to rust, reducing the maintenance cost.

[0027] 4. The mattress sinking construction process is simple and highly automated. The assembled one-way grille soft mattress is towed to the riverbank for mattress sinking through the pulling beam. The pulling beam is towed by a motor. The binding and anti-dumping mechanism and the anti-dumping insurance mechanism are both semi-automatically controlled by the controller. Only one operator is required. In the whole construction process, only the assembly of the one-way grille soft mattress requires manual labor, and other processes are completed by machines. Compared with the existing mattress sinking process, it does not require large-scale machine equipment such as winding drums and the corresponding operators, saving material and human resources, with low cost and good economy.

[0028] 5. The tying and anti-slip mechanism and the anti-slip insurance mechanism are equipped with 3 sets of rotating shafts and anti-slip teeth in total, which can effectively fix the flexible mattress, prevent the one-way grid flexible mattress from sliding, ensure the quality of mattress sinking. Even if one set of rotating shaft - anti-slip teeth fails, the other two sets can still work normally without affecting the construction progress, being safe and reliable. When the flexible mattress sinks along the mattress turning board, it is pulled by one set of anti-slip teeth, which can ensure the flexible mattress sinks smoothly and slowly, further ensuring the quality of mattress sinking.

[0033] As Figure 1 , the flat-bottomed boat for laying the one-way grid flexible mattress 13 is a square boat. Figure 1 The middle and lower part is the bow, the upper part is the stern, the right part is the side close to the river bank, and the left part is the side close to the river center. There is a mattress pulling mechanism 3 on the side close to the river bank, including a traction support 301 that can rotate vertically, a fixed pulley set 302, and a mattress pulling beam 304. The fixed pulley set 302 is fixed on the traction support 301, and the wire rope 303 bypasses the pulley set and is connected to the mattress pulling beam 304. The mattress pulling beam 304 is hinged on the mattress turning board 4 and can move along the mattress turning board 4. The wire rope 303 can pull the mattress pulling beam 304 to move horizontally in the direction perpendicular to the river bank. The mattress pulling beam 304 is a 316L stainless steel beam with a length of 8 m. The mattress turning board 4 is a rectangular stainless steel plate with a length of 10 m and a width of 3 m, which can rotate around the horizontal axis at the edge of the working platform 1 of the flat-bottomed boat, and the included angle with the working platform 1 of the flat-bottomed boat ranges from 0° to 75° (downward). The geotextile storage bin 7 is an empty bin that is sunken downward on the flat-bottomed boat, with a depth of 1.0 - 1.5 m. The width of the geotextile storage bin 7 along the river bank direction is 8 m, which is equivalent to the width of the tying and anti-slip mechanism 6, and the width perpendicular to the river bank direction is 0.5 - 1.0 m. 8 groups of sliding wheels are arranged at equal intervals at the bottom of the geotextile storage bin 7, with an interval of 1 m. The geotextile storage bin 7 is used to store the geotextile 12.

[0034] The external grille storage cage 11 is a removable hanging steel wire cage, cylindrical, used to store the one-way grille 10. The diameter of the external grille storage cage 11 is 1.0~1.2 m, and the width along the river bank is 8 m, which is equivalent to the geotextile storage bin 7. The external grille storage cage 11 is fixed to the side of the flatbed ship near the center of the river channel through three hanging locks. The crane 9 is a swing-type ship crane 9 with a rated lifting weight of 5 tons, 1.5~2.0 m away from the center of the river channel of the flatbed ship. The arm length of the crane 9 is not less than 2.5 times the length of the tying and stopping mechanism 6, and the height of the crane 9 control room is more than 3.5 meters from the flatbed ship. The crane 9 is used to lift the ballast block 8 on the transport ship to the tying and stopping mechanism 6 of the flatbed ship.

[0035] The controller 2 is located at the bow, and is composed of a ship driving module, a ship positioning module, a one-way grid sinking control module, etc. The ship driving module controls the navigation direction and speed of the ship; the ship positioning module is connected to the GPS navigation system, and displays the position coordinates of the ship and the distance between the edge of the ship and the river bank in real time; the one-way grid sinking control module is connected to the tying stop mechanism 6 and the stop insurance mechanism 5, and is used to control the locking and unlocking of the rotating shaft 1 501 and the rotating shaft 2 601, and control the vertical movement of the rotating shaft 1 501 and the rotating shaft 2 601 driven by the electric push rod.

[0036] like Figure 2 The geotextile 12 and the one-way grid 10 are aligned at the ends, and the ballast blocks 8 are dispersed to the dependent warehouse holes according to the designed ballast density. The ballast blocks 8, the one-way grid 10 and the geotextile 12 are fixed at the grid nodes by binding belts to complete the assembly of the one-way grid soft row 13 of the head part.

[0037] like Figure 3 The row stop insurance mechanism 5 is composed of a set of rotating shaft 501 with lifting function and row stop teeth 502. The rotating shaft 501 and the matching row stop teeth 502 are evenly distributed along the river bank direction, with 1 set per meter, a total of 9 sets, and the 2 sets on the edge should be aligned with the two ends of the pull beam 304. The rotating shaft 501 is connected to the electric push rod in the vertical direction, and can move vertically and linearly under the drive of the electric push rod, with a movement rate of 10~20 mm / s and a stroke of 200~400 mm. The row stop teeth 502 are smooth claw-shaped steel teeth, made of 316L stainless steel. The tooth top spacing of two adjacent row stop teeth 502 is 5~10 mm smaller than the spacing of two adjacent transverse ribs of the one-way grille 10, and the angle between adjacent row stop teeth 502 does not exceed 10°. During the sinking construction, the row stop insurance mechanism 5 is used to control the suspension and release of the one-way grille soft row 13.

[0038] like Figure 4, it consists of a grid-shaped knotting and stopping mechanism 6 and two sets of rotating shafts II 601 with lifting functions and their supporting stopping teeth II. The width of a single storage hole of the knotting and stopping mechanism 6 is 15 - 20 mm, the length is 5 - 8 m, and the total width is 8 m, which is aligned with the stopping insurance mechanism 5 and the pulling beam 304 in the riverbank direction. The two sets of rotating shafts II 601 and the supporting stopping teeth II 602 in the knotting and stopping mechanism 6 are evenly distributed in the riverbank direction, with 1 set per meter, a total of 9 sets, and are aligned with the stopping insurance mechanism 5. The two sets of rotating shafts II 601 are spaced 2 - 3 m apart. The two sets of rotating shafts II 601 in the knotting and stopping mechanism 6 are the same as the rotating shaft I 501 in the stopping insurance mechanism 5 and are connected by gears to achieve linkage. The two sets of stopping teeth II 602 in the knotting and stopping mechanism 6 simultaneously grasp two adjacent transverse ribs of the one-way grid 10. During the mattress laying construction, the knotting and stopping mechanism 6 and the stopping insurance mechanism 5 jointly control the suspension and release of the one-way grid 10 mattress.

[0039] The construction method of the flat-bottomed boat for laying the one-way grid mattress 13 in this embodiment includes the following steps:

[0040] S1: Before the flat-bottomed boat enters the site, the steel wire rope 303 is wound around the fixed pulley block 302, one end is connected to the pulling beam 304, and the other end is connected to the winch. Reserve the required amount of geotextile 12 in the geotextile storage bin 7, and reserve a fixed quantity of one-way grid 10 in the externally hung grid storage cage 11.

[0041] S2: Under the control of the ship driving module of the controller 2, the flat-bottomed boat sails to the river section where the one-way grid mattress 13 is to be laid. Under the combined control of the ship positioning module and the driving module, the flat-bottomed boat is moved to a position 3 - 5 m away from the riverbank where the one-way grid mattress 13 is to be laid, and it is ensured that the position of the knotting and stopping mechanism 6 in the riverbank direction coincides with the position where the mattress is to be laid. Then, the ship is fixed at this mattress laying position through the anchoring system. At the same time, the transport ship loaded with ballast blocks 8 moves to the vicinity of the bow of the flat-bottomed boat.

[0042] S3: Lower the mattress turning plate 4 through the motor to ensure that the riverside side of the mattress turning plate 4 can be placed on the riverbank.

[0043] S4: Erect the traction support 301 through the motor, start the winch, and relax the steel wire rope 303 fixed to the pulling beam 304, and pull the pulling beam 304 to the end on the riverside side of the knotting and stopping mechanism 6.

[0044] S5: Then start the assembly of the head part of the one-way grid mattress 13.

Lower the traction support 301 horizontally towards the riverbank side, and tighten the wire rope 303 of the traction and mattress-pulling beam 304 through the winch. The leading part of the traction and mattress-pulling beam 304 and the unidirectional grid mattress 13 move towards the riverbank until the leading part of the unidirectional grid mattress 13 reaches 2 - 3 m above the waterline of the riverbank.

[0047] S8: Anchor the end of the unidirectional grid mattress 13 to the riverbank with anchor rods, steel drills, etc., separate the leading part of the unidirectional grid mattress 13 from the mattress-pulling beam 304, erect the traction support 301 and fix the mattress-pulling beam 304 to complete the laying of the leading part.

[0048] S9: Through the unidirectional grid mattress sinking control module in the controller 2, control the rotation shafts 501 of the mooring and stopping mechanism 6 and the stopping insurance mechanism 5 and the rotation shaft 601 to simultaneously lift under the drive of the electric push rods, lock the rotation shafts 501 and 601, and drive the stopping teeth 502 and the stopping teeth 602 to simultaneously suspend 3 transverse ribs of the unidirectional grid 10.

[0049] S10: Under the combined control of the driving module and the positioning module in the controller 2, translate the flatbed barge 5 - 8 m horizontally perpendicular to the riverbank. After the ship is translated to the set distance, fix the ship through the anchoring system.

[0050] S11: Then, assemble the second part of the unidirectional grid mattress 13. Lift the ballast blocks 8 to the mooring and stopping mechanism 6 and manually place and tie them for fixation. After completing the assembly of the second part of the unidirectional grid mattress 13, lay the second part of the mattress. Through the unidirectional grid mattress sinking control module in the controller 2, control the rotation shafts 501 of the mooring and stopping mechanism 6 and the stopping insurance mechanism 5 and the rotation shaft 601 to simultaneously lower, release the suspension of the stopping teeth 502 and the stopping teeth 602 on the transverse ribs of the unidirectional grid 10, unlock the rotation shafts 501 and 601, and the unidirectional grid mattress 13 smoothly sinks through the sinking flap 4 under the action of its own weight and the traction of the stopping teeth 502 and the stopping teeth 602 to complete the laying of the second part of the mattress.

[0051] S12: When the second part of the soft mattress is moved to the end on the riverside side of the binding and stopping mechanism 6, through the one-way grid mattress laying control module in the controller 2, control the rotation shafts 501 and 601 in the binding and stopping mechanism 6 and the stopping insurance mechanism 5 to rise simultaneously, and lock the rotation shafts 501 and 601, driving the first stopping teeth 502 and the second stopping teeth 602 to synchronously suspend the transverse ribs of the one-way grid 10.

[0052] S13: Under the coordinated control of the driving module and the positioning module in the controller 2, translate the flat-bottomed boat 5 - 8 m perpendicular to the riverbank towards the center of the river. After the boat is translated to the set distance, fix the boat through the anchoring system. Next, assemble the third part of the one-way grid soft mattress 13. After completing the assembly of the third part of the one-way grid soft mattress 13, lay the third part of the soft mattress. And so on, until the one-way grid soft mattress 13 is laid to the designed length, cut the geotextile 12, stop tying the ballast blocks 8, and drive the one-way grid 10 to smoothly slide down through the rotation shafts 501, 601, the first stopping teeth 502, and the second stopping teeth 602 unlocked by the binding and stopping mechanism 6 and the stopping insurance mechanism 5, completing the sinking of the tail of the one-way grid soft mattress 13.
