Description

Solidified soil is anti-loss cover for hydraulic reclamation under water and supporting solidified soil conveyer pipe that uses

The technical field is as follows:

the utility model relates to a solidified soil is hydraulic reclamation with preventing that loss cover and supporting solidified soil conveyer pipe that uses under water.

Background art:

after the pile is sunk on the wind power single-pile foundation, the flow velocity of the seabed around the pile is improved by 0.5-1 time compared with the flow velocity without the pile, and the improvement of the flow velocity breaks the original erosion and deposition balance of the seabed: the sea current can form the horseshoe vortex around the stake, and the stake rear side forms alternate wake vortex line, and the stake side streamline tightens up, and the stake front side still can form the backward flow simultaneously, and the change of these flow fields makes near the stake silt volume of transporting increase, triggers to erode. With the development of the underflow undercutting effect, the erosion pit is gradually deepened, the stability of the offshore wind turbine is continuously reduced, the wind turbine can be seriously destabilized and collapsed, and great loss is caused, so necessary erosion prevention measures need to be taken, an effective protection area is constructed on the sea bed surface around the pile, and the stability of the pile foundation is ensured. High moisture content solidified soil is because cohesion index height, and the scour resistance is strong, and is good with pile foundation laminating nature, and solidification shaping back border can form the gentle slope, is difficult for producing to erode the start, and structural integrity is good, characteristics such as the convenient high efficiency of construction, have been used gradually to the submarine erode the protection.

The solidified soil adopts a slurry pump with a 75kw motor, the flow rate of 250 m/h and the flow rate of 2.2m/s can be realized through a DN200 pipeline, when the solidified soil is pumped into the sea, the solidified soil impacts the seabed and splashes upwards, and due to the influence of sea currents, the solidified soil is washed away by seawater before accumulation is not formed after being sprayed and scattered, so that a large amount of waste is caused.

The specific implementation mode is as follows:

the present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 to 4, the utility model discloses solidified soil is hydraulic reclamation is with preventing cover that runs off, including installation skeleton 1, prevent running off board 2 and flange pipe 3, installation skeleton 1 is the concatenation formula structure, including the skeleton seat 11 of bisymmetry, two skeleton seats 11 concatenations are fixed and form the installation skeleton 1 that has the bucket column structure of a top surface and four sides, and flange pipe 3 is fixed between two skeleton seats 11, for avoiding flange pipe 3 drunkenness from top to bottom, is equipped with two on flange pipe 3's outer wall surface and carries out axial spacing platform 31 to installation skeleton 1. Be equipped with the bolt hole on four sides of installation skeleton 1, prevent losing board 2 and pass through the side fixed connection of bolt and installation skeleton 1, be fixed with L shaped plate 4 between two adjacent prevent losing boards 2.

The water through holes 21 are formed in each anti-loss plate 2, when the anti-loss cover sinks to the seabed, the water through holes 21 facilitate the anti-loss cover to sink, and atmospheric pressure is prevented from being formed in an inner cavity of the anti-loss cover.

Through bolt fixed connection between two skeleton frame 11, all be equipped with fixed ear 13 on the upper and lower terminal surface of skeleton frame 11, wear to establish the bolt on fixed ear with two skeleton frame 11 fixed connection. In order to ensure the mounting and fastening effect of the two skeleton bases 11, fixing lugs 13 can also be arranged on the inner walls of the side edges of the skeleton bases 11.

Each framework seat 11 is provided with a lifting lug 12, and the lifting lug 12 is connected with a hook steel wire rope 5. When the anti-loss shield is used, the steel wire rope 5 is connected with a winch on a construction ship and used for preventing the anti-loss shield from sinking into the seabed.

As figure 4, for the use of the cover that runs off is prevented in the cooperation, the utility model provides a with prevent running off the supporting solidification soil conveyer pipe that uses of cover, this conveyer pipe includes concatenation hose 6 and buffer pipe 7, is equipped with ring flange 61 on concatenation hose 6, and a plurality of concatenation hoses 6 pass through ring flange 61 fixed connection, and wherein the upper and lower flange face fixed connection in two sections concatenation hoses 6 and the flange pipe 3, ring flange 61 fixed connection on the concatenation hose 6 of buffer pipe 7 and bottom, and buffer pipe 7 arranges in that four prevent inside the cavity that the board 2 that runs off encloses.

The utility model provides a buffer tube 7 adopts oxford to make, fixes the flange dish in the upper end of buffer tube 7, for the convenience end of sinking, has the counter weight circle 71 that metal material made at the bottom mounting of buffer tube 7. The height difference between the counterweight ring 71 and the bottom surface of the anti-loss plate 2 is 0.5-1m.

When pumping solidified soil into the scouring pit around the seabed pile, the conveying pipe sinks to the scouring pit along with the anti-loss cover, then solidified soil is pumped into the conveying pipe, the solidified soil is shielded through the anti-loss cover, the loss of the solidified soil can be effectively reduced, in the process of pumping the solidified soil, part of the solidified soil can slowly flow out through the water through holes 21, and the flowing little solidified soil is slowly self-leveled according to the sea current. After the solidified soil in each anti-loss cover is pumped into a required amount, the anti-loss cover is lifted by the overwater winch, and the solidified soil in the anti-loss cover slowly self-levels according to the ocean current, so that the solidified soil is solidified in the self-leveling process. Then the conveying pipe sinks to another pump inlet point in the flushing pit again along with the anti-loss cover to carry out repeated operation.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications can be made without departing from the principle of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
