Description

Technical Field

[0001] The invention belongs to the field of water conservancy engineering, and in particular relates to a Binger stone cage laying device and a construction method for underwater engineering construction. Background Art

[0002] At present, in water conservancy construction such as embankment protection and river management, the placement of gabions filled with stones is mainly carried out by hanging and throwing. The hanging and throwing is mostly carried out on land, that is, the crane is transported to the embankment and at a certain distance from the placement point, the gabions filled with stones are piled on the embankment, and then the crane lifts the gabions one by one and drops them to the construction location, that is, the placement point.

[0003] For the above-mentioned hoisting method, since the Binger gabions are made of metal mesh and are mostly rectangular or cylindrical in structure, the stones in the Binger gabions are heavy, and the gabions are deformed during hoisting, making it difficult to ensure the initial state of the gabions. The state of the Binger gabions after being placed changes, and they cannot be neatly stacked, affecting the effect of water conservancy construction. In addition, since the Binger gabions are hoisted and placed by cranes, the position, state and direction of the Binger gabions must be repeatedly adjusted during the hoisting process to try to make the Binger gabions neatly stacked in the water after being placed, which affects the placement speed and the placement construction effect is not ideal. Summary of the invention

[0004] In view of this, the present invention aims to propose a Binge gabion laying device and method for underwater engineering construction, so as to improve the convenience of laying Binge gabions in water, and improve the construction effect of laying Binge gabions in water and reinforcing and protecting the underwater slope of the river slope.

[0005] In order to achieve the above-mentioned purpose, the technical scheme of the present invention includes a Binger gabion laying device and a construction method for underwater engineering construction. The technical scheme of the Binger gabion laying device for underwater engineering construction is first described as follows:

[0006] A Binger gabion laying device for underwater engineering construction includes a tugboat and a support plate. A jacking element is vertically arranged at the left and right ends of the tugboat and near the stern. The movable ends of the two jacking elements are connected by a support beam. The front end of the support plate is rotatably connected to the front end of the tugboat through an axis, and the middle and rear part of the support plate is placed on the support beam and supported by the support beam.

[0007] Furthermore, the lifting element is an oil cylinder, whose push rod is downward and connected and fixed to the tugboat, and whose cylinder body is a movable end and is connected and fixed to the support beam.

[0008] Furthermore, the front end of the support plate protrudes beyond the front edge of the tugboat deck.

[0009] Furthermore, baffles are respectively provided upwards at the left edge, the right edge and the rear edge of the support plate.

[0010] Furthermore, a gantry is provided at the front end of the tugboat, and the support plate passes through the gantry.

[0011] Furthermore, railings are respectively provided at the left end, the right end and the rear end of the tugboat deck.

[0012] The above content is a description of the technical solution of the Binger gabion laying device for underwater engineering construction. The following is a description of the Binger gabion laying method for underwater engineering construction:

[0013] A Binge gabion laying method comprises the following steps:

[0014] S10: Determine the placement position of the Binge gabion on the water surface;

[0015] Determine the placement of the Binger gabion on the water surface according to the location of the underwater slope that needs to be reinforced;

[0016] S20. Laying metal mesh for Binger gabions on tugboats:

[0017] First, the metal mesh used for making the Binger gabion is spread out and laid flat on the support plate of the tugboat. The metal mesh is the bottom mesh. Then, the side mesh is tied to the edge of the bottom mesh to form a mesh box with an open top.

[0018] S30: Fill the mesh box with stones evenly:

[0019] Ensure that the stone filling size meets the design requirements;

[0020] S40: Sealing the mesh box:

[0021] Tie and seal the top opening of the mesh box to make the gabion and the filled stones form a whole;

[0022] S50: Move the tugboat and position it:

[0023] The tugboat moves to the placement position of the gabion and positions the tugboat according to the placement position of the gabion on the water surface determined in step S10, at which time the tugboat is perpendicular to the river slope;

[0024] S60: Gabion cage placement:

[0025] The rear end of the support plate flips upward to a set angle, the support plate tilts, the gabion gabion slides down, and the gabion gabion is thrown to the gabion laying position on the underwater slope in the vertical direction of the river slope.

[0026] Further, in step S60, while the Binger gabion slides into the water, the tugboat sails away from the river bank in a direction perpendicular to the river bank.

[0027] Further, step S20 uses C-shaped nails or steel wires to tie the side net and the bottom net together;

[0028] In step S40, the top opening of the mesh box is tied and sealed using C-shaped nails or steel wires; this tying method ensures that the Binger gabion structure is stable and not loose, and can maintain its shape underwater and withstand the impact of water flow.

[0029] Furthermore, in step S50, an anchor rod is set on the river bank, and the tugboat and the anchor rod are fastened together with ropes to achieve positioning of the tugboat.

[0030] Furthermore, in step S50, the tugboat is positioned in such a manner that the front end position of the support plate on the tugboat corresponds to the water surface placement position.

[0031] Furthermore, in step S20, before the metal mesh is unfolded and laid on the support plate, a geotextile is first laid on the support plate, and then the metal mesh is laid on the geotextile to manufacture a mesh box.

[0032] Compared with the prior art, the Binger gabion laying device for underwater engineering construction described in the present invention has the following advantages:

[0033] (1) The present invention uses a tugboat to carry the gabion and tilt the support plate to slide the gabion into the water, thereby completing the underwater laying operation. This laying method can keep the gabion in its initial state, achieve neat stacking in the water, and ensure the reinforcement and protection construction effect of the underwater slope surface of the river slope.

[0034] (2) In the present invention, the position and orientation of the tugboat can be adjusted according to the delivery requirements, so that the orientation of the carried gabions meets the delivery requirements, thereby improving the accuracy and convenience of the delivery of the gabions.

[0035] (2) In the present invention, the lifting element adopts an oil cylinder, whose push rod faces downward and is connected and fixed to the deck of the tugboat, and whose cylinder body is connected and fixed to the support beam. This installation method saves space, makes the height position of the support plate lower and close to the deck of the tugboat, and facilitates the flipping of the support plate, so that the carried Binger gabion can be put into the water and laid.

[0041] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0042] Embodiment 1: A Binger stone cage laying device for underwater engineering construction, such as Figure 1 As shown, it includes a tugboat 1, a support plate 2, a support beam 8 and two lifting elements 4. The left end, right end and rear end (stern position) of the deck of the tugboat 1 are respectively provided with railings. The two lifting elements 4 are vertically arranged and symmetrically arranged on the left and right sides of the tugboat 1 at the middle and rear part of the tugboat 1. The lifting elements 4 and the tugboat 1 are connected and fixed, and the movable ends of the two lifting elements 4 are connected through the support beam 8. The support plate 2 is located above the tugboat 1, and the left edge, right edge and rear edge of the support plate 2 are respectively provided with baffles 21 upward. Its front end is rotatably connected to the front end of the tugboat 1 through a horizontal axis (not shown) perpendicular to the hull direction of the tugboat 1. The support plate 2 can be turned around the axis, and the middle and rear part of the support plate 2 is placed on the support beam 8 and supported by the support beam 8. In this structure, after the filling and binding of the gabion cage is completed on the support plate 2, the two lifting elements 4 drive the support beam 8 to move upward, thereby driving the support plate 2 to flip upward around the axis, and the support plate 2 tilts to unload the gabion cage filled with stones.

[0043] In the present invention, the lifting element 4 is preferably an oil cylinder and is installed on the deck of the tugboat 1. The specific arrangement and connection structure are as follows: the push rod of the lifting element 4 faces downward and is fixed to the fixed block 3 provided on the deck of the tugboat 1, that is, the lifting element is connected and fixed to the tugboat 1 through its push rod, and its cylinder body is the movable end, and the lower part of the cylinder body is connected and fixed to the support beam 8. This structure makes the height position of the support plate 2 on the tugboat 1 lower, that is, the support plate 2 is close to the deck of the tugboat 1 as a whole, which is convenient for personnel to tie up the gabion cage, and the front end of the support plate 2 is as close to the water surface as possible after the flipping, which is convenient for the placement of the gabion cage and improves the accuracy of the placement position of the gabion cage.

[0044] Preferably, the front end of the support plate 2 protrudes from the front edge of the deck of the tugboat 1. After the support plate 2 is turned upward, its front edge is located in front and below the front edge of the deck of the tugboat 1, and the front edge of the support plate 2 is closer to the water surface, so as to facilitate the positioning of the gabion stone cage placement point and improve the accuracy of the gabion stone cage placement position.

[0045] In the present invention, a gantry 5 is provided at the front end of the tugboat 1 , and the support plate 2 passes through the gantry 5 .

[0046] In the present invention, a tying pile 6 is provided at the left end and / or the right end of the cleat of the tugboat 1, and the tying pile 6 is used to install ropes to be connected with fixing members on the river slope, such as anchor rods, to position the tugboat.

[0047] The present invention realizes the placement and laying of gabion gabions in water by flipping the support plate 2, thereby improving the accuracy of the placement position. When placing the gabions, the gabions can maintain their initial state and be neatly stacked and laid, thereby ensuring the underwater construction effect. The problem of repeatedly adjusting the direction of the gabions to meet the placement requirements during conventional hoisting placement of gabions is solved. Therefore, the gabions placed by the device have a fast placement speed and an accurate placement position, and can be widely used in water conservancy construction fields such as water conservancy projects, coastal protection projects, and river management.

[0048] The above is a description of an embodiment of a Binge stone cage laying device. The following is a description of a Binge stone cage laying method using the device through embodiment 2:

[0049] A Binge stone cage laying method, the flow chart is as follows Figure 2 As shown, the following steps are included:

[0050] S10: Determine the placement position of the Binge gabion on the water surface;

[0051] Before construction, the location of the slope that needs to be protected or reinforced is determined through underwater measurement of the river slope in accordance with the design requirements. The placement position of the Bing gabions on the water surface is determined based on the underwater slope reinforcement position of the river slope, that is, the laying position of the Bing gabions. The Bing gabions are placed at the water surface placement position to reach the underwater slope of the river slope that needs to be protected or reinforced.

[0052] S20. Laying the metal mesh for Binger gabion on tugboat 1:

[0053] First, the metal mesh used for making the Binger gabion is spread out and laid flat on the support plate 2 of the tugboat 1. The metal mesh is called the bottom mesh. Then, the side mesh is tied to the edge of the bottom mesh using C-shaped nails or steel wires to finally form a mesh box with an opening on the top.

[0054] S30: Use engineering equipment such as excavators or cranes to evenly fill the mesh box with stones, distribute the stones evenly in the mesh box, and level the stones so that the stone filling size meets the design requirements.

[0055] S40: Sealing the mesh box:

[0056] Use C-shaped nails or steel wires to tie and seal the top opening of the mesh box, ensuring that all edges of the mesh box are tied and sealed to prevent stones from scattering out of the box, so that the Binger stone cage and the filled stones form a whole.

[0057] S50: Move the tugboat and locate the drop location:

[0058] The tugboat 1 is moved to the construction position of the gabion gabion laying, and the tugboat is oriented perpendicular to the river slope, and then the tugboat 1 is positioned so that the surface placement position of the gabion gabion meets the placement requirements and corresponds to the underwater placement position of the gabion gabion;

[0059] Preferably, the deck height of the tugboat 1 is slightly higher than the water surface, and the front end of the support plate 2 extends out of the front end of the tugboat deck. When the support plate is flipped upward around the axis, the front end of the support plate 2 basically contacts the water surface, and the Binger gabion is dropped from the front end of the support plate 2. Therefore, the front end position of the support plate 2 is positioned so that it is set corresponding to the water surface drop position, and the Binger gabion is dropped from this position.

[0060] For example, the positioning method of the tugboat is: an anchor rod is set on the river slope, and the rope set on the tie-down pile on the tugboat cleat is tied to the anchor rod, thereby fixing the position of the tugboat, so that the placement point of the Binger gabion on the water surface after the support plate 2 is turned over corresponds to the underwater laying position of the Binger gabion on the river slope;

[0061] S60: Gabion cage placement:

[0062] After the position of the tugboat 1 is fixed, the jacking element is lifted, and the support plate 2 is flipped upward to a set angle around the axis set at its front end and connected to the tugboat 1. At this time, the support plate is in an inclined state with the rear end facing upward and the front end facing downward. The gabion gabion on the support plate slides down and is thrown to the gabion laying position on the underwater slope in a direction perpendicular to the river slope.

[0063] In the present invention, in step S60, after the front end of the Binge gabion enters the water, the tugboat starts and drives away from the river slope in a direction perpendicular to the river slope. At this time, the Binge gabion is put into the water and the tugboat drives away from the river slope. During the operation, the inclination angle of the Binge gabion gradually decreases, that is, its inclination angle when entering the water gradually decreases, so that the Binge gabion can maintain its shape in the water, improve the accuracy of the placement position and the flatness of the Binge gabion after placement, and improve the neatness of the stacking of multiple gabions, thereby improving its slope protection effect.

[0064] In the present invention, in order to improve the smooth sliding of the Binger gabion, in step S20, before the metal mesh is unfolded and laid on the support plate 2, a geotextile is first laid on the support plate 2, and then the metal mesh is laid on the geotextile to manufacture a mesh box. When the Binger gabion is put into the water, it slides down together with the geotextile.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
