Description
Technical Field
[0001] The utility model relates to the field of sea bridge pile foundation construction, in particular to a pulping ship. Background Art
[0002] Due to the scouring effect of water flow over the years, the seabed around the pile foundation of the cross-sea bridge is often over-scoured, and the resulting scour pits will threaten the long-term safety and stability of the bridge structure. In the existing technology, most of the traditional methods of throwing bagged gravel and laying soft rafts are used to solve this problem. However, engineering practice and related literature reports have shown that it is difficult to completely backfill the scour pits with traditional bagged gravel, and the bagged gravel protection structure cannot be effectively leveled, making it difficult to ensure a good protective effect; laying soft rafts can reduce the water flow speed around the pile foundation to a certain extent and delay the further development of the scour pits, but it cannot fundamentally solve the scour pit problem.
[0003] Since the mud-solidified soil backfill material has good fluidity, it can completely fill and level the scour pit and the gap between the pile foundation and the seabed, and the strength after solidification is as high as 700kPa. The protective structure has good integrity, a flat surface and can form a certain slope, and has very good anti-scour ability. Therefore, the protective effect of the mud-solidified soil pile foundation scour protection technology is significantly improved compared with the existing technology, and can solve the scour problem of the pile foundation of the cross-sea bridge. However, the existing offshore pulping vessels usually have pulping and slurry storage structures set together, which limits the slurry storage capacity of the slurry storage structure, and the single-time grouting volume of a single ship is small, which leads to a long construction period and high construction costs. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a pulping vessel to overcome the defects in the prior art that the pulping and pulping storage structures of offshore pulping vessels are usually arranged together, thereby limiting the pulping capacity of the pulping storage structure, and the single grouting volume of a single vessel is small, which in turn leads to a long construction period and high construction costs, and to provide a pulping vessel.
[0005] The utility model solves the above technical problems through the following technical solutions:
[0006] A pulping ship, comprising a mud pool and a stirring device, wherein the stirring device comprises a moving platform and a stirring part, and the moving platform is located outside the mud pool;
[0007] The stirring part is located inside the mud pool, and the stirring part can stir the slurry in the mud pool. The stirring part can move along with the movement of the mobile platform.
[0008] The technical solution provides a pulping ship, which includes a mud pool and a stirring device. The stirring device includes a mobile platform and a stirring part. The mobile platform is located outside the mud pool; the stirring part is located inside the mud pool. The stirring part can stir the slurry in the mud pool, and the stirring part can move with the movement of the mobile platform. In this solution, the stirring device and the mud pool are separated, and the mobile platform has a relatively free movement range outside the mud pool, thereby driving the stirring part to move in various places in the mud pool to fully stir the pulping raw materials in the mud pool to form mud for grouting construction. Since the stirring part has a large stirring range, the upper limit of the capacity of the mud pool is correspondingly high, and the single-time grouting volume of a single ship is large, which can shorten the construction period and reduce construction costs.

[0052] Two preferred embodiments are given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.
[0053] Example 1
[0054] like Figure 1-Figure 6 As shown, this embodiment provides a pulping vessel, which includes a mud pool 1 and a stirring device 2. The stirring device 2 includes a mobile platform 21 and a stirring portion 22. The mobile platform 21 is located outside the mud pool 1. The stirring portion 22 is located inside the mud pool 1. The stirring portion 22 can stir the slurry in the mud pool 1, and the stirring portion 22 can move with the movement of the mobile platform 21.
[0055] In this way, a pulping vessel is provided, which includes a mud pool 1 and a stirring device 2. The stirring device 2 includes a mobile platform 21 and a stirring part 22. The mobile platform 21 is located outside the mud pool 1; the stirring part 22 is located inside the mud pool 1. The stirring part 22 can stir the slurry in the mud pool 1, and the stirring part 22 can move with the movement of the mobile platform 21. In this scheme, the stirring device 2 and the mud pool 1 are separated, and the mobile platform 21 has a relatively free movement range outside the mud pool 1, thereby driving the stirring part 22 to move around in the mud pool 1, so as to fully stir the pulping raw materials in the mud pool 1 to form mud for grouting construction. Since the stirring part 22 has a large stirring range, the upper limit of the capacity of the mud pool 1 is correspondingly high, and the single-time grouting volume of a single ship is large, which can shorten the construction period and reduce the construction cost. In this embodiment, the capacity of a single pulping pool 1 on the pulping ship is about 400 cubic meters, and the total capacity of two identical pulping pools 1 is about 800 cubic meters. Considering that during pulping and stirring, in addition to the original pulping raw materials in the pulping pool 1, there is also construction water injected from the self-made pulping pool 1, the single-time grouting volume of a single ship can reach about 1,000 to 2,000 cubic meters. Therefore, the number of round trips between the dock and the construction site is small, which can well ensure the construction period. In other embodiments, the capacity of the pulping pool can also be adjusted accordingly according to the size of the pulping ship.
[0056] In this embodiment, the mud pool 1 is located on the surface of the deck 3 of the pulping ship. In this way, the on-site construction of the mud pool 1 can be facilitated, and a larger buildable space is provided for the mud pool 1.
[0057] In this embodiment, the two mud pools 1 are symmetrically distributed in the middle of the deck 3, which can increase the stability of the pulping ship, reduce the lateral overturning moment, and improve the safety performance of the pulping ship; the mobile platform 21 is located on the surface of the deck 3 between the two mud pools 1, which can facilitate the stirring part 22 driven by a single mobile platform 21 to stir the mud pools 1 on both sides, reduce the number of mobile platforms 21 required, and shorten the connection between the mobile platform 21 and the stirring part 22; and the movement area of the mobile platform 21 is close to the bow and tail center axis of the pulping ship, which further increases the stability of the pulping ship, reduces the lateral overturning moment, and improves the safety performance of the pulping ship. In this embodiment, a total of two mobile platforms 21 and stirring parts 22 are set; in other embodiments, the number of mobile platforms 21 and stirring parts 22 can also be set according to specific construction needs.
[0058] In this embodiment, the pulping ship further includes a solidified soil slurry pump 4, which can pump the mud in the mud pool 1 to the outside of the pulping ship, so that the mud can be pumped with a relatively simple structure.
[0059] In this embodiment, the stirring device 2 is an excavator, and the stirring part 22 is a bucket capable of spiral stirring. The bucket can hoist the solidified soil mud pump 4 into the mud pool 1. In this way, the technical effect of fully stirring the slurry raw materials in the mud pool 1 to form mud and pumping the mud in the mud pool 1 to the outside of the slurry ship can be achieved with a relatively simple structure.
[0060] In this embodiment, the pulping ship also includes a submersible pump 5, a lifting bracket 6, and a pumping pipe 7. The submersible pump 5 is connected to the mud pool 1 through the pumping pipe 7. The lifting bracket 6 can lift the submersible pump 5 into the seawater outside the pulping ship. In this way, the technical effect of pumping seawater into the mud pool 1 and mixing it with the pulping raw materials to form mud can be achieved with a relatively simple structure. There is no need to carry additional construction water on board, which further increases the grouting volume of a single ship at a time. In this embodiment, the lifting bracket 6 is located at the bow of the pulping ship. Please refer to the structure of the lifting bracket 6 for details. Figure 5 , which is a rotatable column cantilever crane. The rotatable column 61 is made of two large and small steel pipes. The large steel pipe is welded on the deck of the pulping ship, and the small steel pipe is inserted into the large steel pipe and has a built-in bearing to realize the rotation of the column; the cantilever structure 62 is welded by I-beams and forms a stable triangular structure with the column; the lifting bracket is equipped with a lifting device and a lifting device 63, which can lift pumps, offshore pipelines, pump heads, etc. Of course, in other embodiments, the lifting bracket can also adopt other structures.
[0061] In this embodiment, the pumping pipe 7 includes a plurality of pipe sections (not shown in the figure), and the plurality of pipe sections can be spliced together, which can improve the mobility of offshore construction. In this embodiment, the pipe sections are made of steel to avoid corrosion from seawater; the pipe sections are flange-connected, and the pumping pipe 7 is fixedly installed on one side of the mud pool 1, so as to achieve mobile construction with a relatively simple structure. Of course, in other embodiments, the pumping pipe 7 can also include other structures.
[0062] In this embodiment, the mud pool 1 is surrounded by steel plates 11. This can facilitate the on-site construction of the mud pool 1, and can reinforce the mud pool 1 to avoid structural damage to the mud pool 1.
[0063] In this embodiment, the steel sections 12 on the outside of the mud pool 1 are welded into a triangle, which can support the mud pool 1 and reduce the lateral deformation of the pool wall.
[0064] In this embodiment, the deck 3 is equipped with a generator set, a power distribution cabinet and a container house to ensure the power supply for offshore construction. Of course, in other embodiments, the deck 3 may also be equipped with other supporting parts.
[0065] Example 2
[0066] This embodiment provides a pulping boat, whose structure is roughly the same as that of embodiment 1, except that: Figure 7 As shown, the pulping vessel further comprises a gantry 8 , which is movable and can hoist the solidified soil slurry pump 4 into the slurry pool 1 .
[0067] In this way, the stirring part 22 and the solidified soil slurry pump 4 can be separated into two places with a relatively simple structure so that the solidified soil slurry pump 4 can move independently and the slurry in the slurry pool 1 can be pumped out of the slurry making ship.
[0068] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
