[0002] Since the gravity dock relies on its own weight to maintain stability, it has high requirements for the bearing capacity of the foundation. Most of the main bodies of gravity docks adopt caisson pier structures. After the installation of the caisson is completed, it is necessary to fill the inside of the caisson with stones or sand to ensure that the caisson has enough deadweight to maintain its own stability. At present, the sand filling of gravity dock caissons mainly adopts the process of filling sand with ship-borne loaders or excavators. The deck barge is docked and the loader fills the sand into the caisson. After loading, the deck barge is moved to one side of the gravity dock caisson, and the loader or excavator on the deck barge fills the sand on the ship into the gravity dock caisson. This process is greatly affected by sea conditions and requires multiple ships to operate in a continuous flow, which is expensive and costly. Utility Model Content

DETAILED DESCRIPTION

[0017] like Figure 1-3 As shown, the gravity-type wharf caisson sand filling device provided by the utility model comprises a sand filling pipe 1, a water inlet pipe 2 and a sand-water mixing pipe 3. The sand filling pipe 1 is a funnel-shaped structure. A sand filling inclined pipe 11 is arranged at the bottom of the sand filling pipe 1, and the lower end of the sand filling pipe 1 is arranged on a supporting frame 5; a water inlet pipe 2 is arranged on one side of the sand-water mixing pipe 3, and a sand outlet pipe 4 is arranged on the other side of the sand-water mixing pipe 3. The upper end of the sand-water mixing pipe 3 is connected to the sand filling pipe 1 through the sand filling inclined pipe 11.

[0018] like Figure 4As shown, when the utility model is used, first, the support frame 5 is placed on the shore close to the sand-filled gravity wharf caisson 6 and level with the ground, and the sand outlet pipe 4 is placed above the gravity wharf caisson. Then, the water inlet pipe 2 is connected to the water pump 7 through the flange and the water pump connecting pipe; then, the sand is filled into the sand filling pipe 1 by the loader, and the sand enters the sand-water mixing pipe 3 through the sand filling inclined pipe 11. The water flow of the water inlet pipe 2 provides horizontal impact force for the sand falling from the sand filling inclined pipe 11, so that the sand and water in the sand-water mixing pipe 3 are driven into the gravity wharf caisson 6 through the sand outlet pipe 4. The utility model does not need to use a ship-borne loader or excavator to fill sand, and replaces sea filling with sand on land, which can reduce the restrictions of sea conditions on caisson sand filling construction, reduce the use of ships, improve construction efficiency, and reduce construction costs.

[0019] The support frame 5 includes four support rods 51, the upper ends of the four support rods 51 are welded to the lower end of the sand filling pipe 1, the lower ends of the two left support rods 51 are welded to the water inlet pipe 2 through the fixing rods 52, and the lower ends of the two right support rods 51 are welded to the sand-water mixing pipe 3 through the fixing rods 52. The support frame 5 fixes the sand filling pipe 1, the water inlet pipe 2, the sand-water mixing pipe 3 and the sand outlet pipe 4 on the wall of the gravity wharf caisson 6, which is convenient for filling stones or sand inside the gravity wharf caisson 6 and improving construction efficiency.

[0020] The side of the sand filling pipe 1 is also provided with an auxiliary water inlet pipe 12. The water flow of the auxiliary water inlet pipe 12 provides horizontal impact force for the sand falling from the top of the sand filling pipe 1, prevents sand from piling up, and improves construction efficiency.

[0021] The sand-water mixing pipe 3 and the sand-discharging pipe 4 are provided with a stepped buffer pipe 31. The stepped buffer pipe 31 makes the movement of the sand pattern consistent with the water flow direction and does not produce accumulation at the bottom of the sand-water mixing pipe 3 and the sand-discharging pipe 4.

[0022] The rear end of the water inlet pipe 2 is provided with a narrow water inlet pipe 21, and the water inlet pipe 2 is connected to the sand-water mixing pipe 3 through the narrow water inlet pipe 21. The narrow water inlet pipe 21 can increase the water flow rate of the water inlet pipe 2, and facilitate the sand and water in the sand-water mixing pipe 3 to be driven into the gravity wharf caisson 6 through the sand outlet pipe 4, thereby improving construction efficiency and reducing construction costs.

[0023] The gravity-type wharf caisson sand filling device provided by the utility model has a sand filling pipe 1, a water inlet pipe 2, a sand-water mixing pipe 3 and a sand outlet pipe, which are tubular structures and can effectively complete the long-distance transportation of medium-coarse sand. Compared with the water sand-blasting method in hydraulic engineering that uses a ship-borne loader or excavator to fill sand in the past, the device is mainly composed of a steel cylinder structure such as a sand filling pipe 1, a water inlet pipe 2, a sand-water mixing pipe 3 and a sand outlet pipe 4. The sand filling pipe 1 is filled with medium-coarse sand, and the sand falls into the sand-water mixing pipe 3 at a certain angle through the sand filling inclined pipe 11; the water inlet pipe 2 is connected to a water pump 7, and the sand falling from the sand filling pipe 1 is sent to the side of the sand outlet pipe 4 by the impact force of the water pump 7, so as to achieve the purpose of filling sand into the gravity-type wharf caisson 6 on land, which can effectively improve the efficiency of sand filling of the gravity-type wharf caisson, reduce the use of ship machinery, and reduce construction costs. The device replaces sea sand filling with land sand filling, reduces the use of ships during construction, and effectively reduces construction costs. Moreover, compared with offshore sand filling, onshore sand filling is less affected by weather, which can greatly improve work efficiency and ensure construction safety.

[0024] The utility model provides a gravity-type wharf caisson sand filling device, the bottom of the sand filling pipe 1 is connected to the support frame 5 by welding, the support frame 5 is made of channel steel welding, and provides support for the sand filling pipe 1, the water inlet pipe 2, the sand-water mixing pipe 3 and the sand outlet pipe 4. The top sand inlet of the sand filling pipe 1 is a cylindrical structure with a diameter of 4m, and the side 2m away from the top of the sand filling pipe 1 is connected to the auxiliary water inlet pipe 12. The auxiliary water inlet pipe 12 is made of a steel pipe with a diameter of 0.8m. The water inlet of the water inlet pipe 2 is made of a steel pipe with a diameter of 2m. The sand outlet pipe 4 is made of a steel pipe with a diameter of 1.8m, and the sand outlet pipe 4 faces the top of the gravity-type wharf caisson 6, so that the sand can accurately fall into the cell bin of the gravity-type wharf caisson 6.

[0025] The working principle of the gravity dock caisson sand filling device provided by the utility model is as follows: the device is placed on the shore close to the sand-filled gravity dock caisson 6 and level with the ground, the sand outlet faces the gravity dock caisson 6 to be filled with sand, and the water inlet pipe 2 and the auxiliary water inlet pipe 12 are respectively connected to the water pump 7. The sand is filled into the sand filling pipe 1 by a loader, and the water pump 7 is started at the same time. After the sand falls into the sand-water mixing pipe 3 under the action of its own weight, it is affected by the horizontal impact force of the water inlet pipe 2 and ejected from the sand outlet pipe 4 to accurately fill the gravity dock caisson 6 to be filled with sand. The sand discharge distance is completed by adjusting the water pump power according to the actual distance between the device and the gravity dock caisson 6.

[0026] The installation, connection or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indicators of all its components are its own technology, as long as it can achieve its beneficial effects, it can be implemented. The water pump 7 used above is a common device on the market. When it is bought back for use, it only needs to be connected according to the instruction manual purchased together, so it will not be repeated here.

[0027] The technical solution of the present invention is not limited to the scope of the embodiments of the present invention, and the technical contents not described in detail in the present invention are all well-known technologies.
