Description

Technical Field

[0001] The invention relates to the technical field of deep-sea riprap equipment, and in particular to a leveling frame device of a riprap leveling ship. Background Art

[0002] With the development of infrastructure technology, the construction of long-distance cross-sea channels now generally adopts a combination of bridges and tunnels. There are two common ways to build submarine channels. One is to use a shield machine to open a tunnel under the seabed to form a submarine channel, and the other is to lay multiple immersed tubes on the seabed and then connect multiple immersed tubes to form a submarine channel. Among them, immersed tube tunnels have lower foundation requirements and are particularly suitable for engineering sites with soft foundations, shallow riverbeds or seabeds that are easy to use water dredging facilities for foundation trench excavation. Due to its small burial depth, the total length of the tunnel line including the connecting section is significantly shorter than that of tunnels built by mining and shield methods. The cross-section shape of the immersed tube can be round or square, and the choice is flexible. The processes of foundation trench excavation, pipe segment prefabrication, floating sinking and internal paving can be carried out in parallel, with less interference with each other, and the quality of pipe segment prefabrication is easy to control, so it is increasingly valued.

[0003] The construction steps of the immersed tube tunnel include foundation trench excavation, foundation construction, immersed tube installation and joint treatment. The foundation trench excavation is to use bucket dredgers, suction dredgers or dredgers with mud cutting heads, cranes with claw buckets and other equipment to open up the foundation trench; the foundation construction includes laying coarse stones first and then fine stones; the immersed tube installation includes hoisting the immersed tube and backfilling gravel on both sides of the immersed tube.

[0004] The patent document with application number 201310009177.3 and publication date 2016.02.10 discloses a platform-type riprap and leveling boat and its construction method. The leveling boat includes: a hull, a first GPS positioning system and an operating room respectively arranged on the hull, a moon pool arranged in the center of the hull, a leveling guide mechanism across the moon pool, a riprap and leveling device installed on the leveling guide mechanism, and a stone conveying mechanism. The hull is stable, the construction efficiency and safety are high, and the flatness of the base bed after construction is high. The leveling boat is lifted off the sea / river surface by four pile legs and overloaded, so as to ensure the stability of the hull of the leveling boat during the construction process, and is less affected by natural conditions such as waves, currents, and wind during the riprap and leveling process. The second GPS positioning system on the top of the riprap pipe receives three-dimensional coordinate data and combines the length of the riprap pipe, the inclination angle of the riprap pipe, and the stroke of the bottom hydraulic cylinder to control the elevation of the crushed stone base bed, and the measurement accuracy is precisely controlled.

[0005] The stone throwing method of this scheme is achieved by moving the top of the riprap tube. Due to the long length and heavy weight of the riprap tube, when the stone is thrown by moving the top of the riprap tube, due to the inertia during movement and the impact of the water flow on the riprap tube, the bottom of the riprap tube will swing severely and deviate from the movement trajectory of the top of the riprap tube, and the thrown stones will therefore fall inaccurately and be irregularly arranged. Summary of the invention

[0006] In order to solve the problems existing in the prior art, the present invention provides a leveling frame device for a riprap leveling ship, which solves the problem that the riprap pipe in the prior art has long length and heavy weight, resulting in inaccurate landing points and irregular arrangement of stones.

[0007] To achieve the above-mentioned purpose, the technical scheme of the present invention is: a leveling frame device for a riprap leveling ship, comprising a U-shaped base frame, a leveling frame trolley spanning the U-shaped base frame is slidably provided along the transverse direction of the U-shaped base frame, a leveling frame trolley driving device for driving the leveling frame trolley to slide along the transverse direction of the U-shaped base frame is provided on the U-shaped bracket, a leveling frame trolley is slidably provided on the leveling frame trolley, a leveling frame trolley driving device for driving the leveling frame trolley to slide along the length direction of the leveling frame trolley is provided on the leveling frame trolley, and more than three pile leg devices are also provided on the U-shaped base frame; a hopper device is provided on the leveling frame trolley.

[0008] In the above structure, the pile leg device supports the U-shaped base frame on the seabed, and the hopper device for containing crushed stones moves along the transverse and longitudinal direction of the U-shaped base frame with the leveling frame trolley. In this way, the crushed stones to be thrown out have a stable movement trajectory and will not be affected by the inertia and water flow impact during movement.

[0010] The above arrangement requires that the transverse structure pipe group of the leveling frame trolley needs to make reciprocating motion, and in order to ensure the reliability of the motion, the deformation of the transverse structure pipe group must be strictly controlled. A buoyancy cavity is provided on the transverse structure pipe group, and the transverse structure pipe group is supported by the buoyancy, which is equivalent to adding support points to the transverse structure pipe group, which can effectively support the transverse structure pipe group and prevent the transverse structure pipe group from deformation.

With the above arrangement, the hollow tube is light in weight and is convenient for setting up the buoyancy chamber; the arrangement in which the center of the first buoyancy chamber coincides with the center of the first structural tube; and the center of the second buoyancy chamber coincides with the center of the second structural tube can keep the structure of the U-shaped base frame balanced and stable.

[0013] In the above structure, the double-beam structure of the leveling frame trolley and the leveling frame trolley are stable and not easy to deform. A trolley buoyancy chamber is provided on the trolley walking beam, and the buoyancy is used to support the trolley walking beam, which is equivalent to adding a support point on the trolley walking beam, which can effectively support the trolley walking beam and prevent the trolley walking beam from deforming; the center of the first trolley buoyancy chamber coincides with the center of the first structural beam; the setting that the center of the second trolley buoyancy chamber coincides with the center of the second structural beam can keep the structure of the trolley walking beam balanced and stable.
