Description

Technical Field

[0001] The utility model relates to the technical field of dock structure construction, in particular to a grouting device for installing underwater fender screws. Background Art

[0002] In recent years, my country's port and wharf construction has begun to develop towards deepwater and large-scale development. At the same time, small vessels still exist at this stage. The depth and draft of these existing ships are significantly different from those of large ships. Therefore, the design of docking facilities at many berths needs to consider the ship sizes of large and small ships simultaneously to meet their docking requirements. For high-pile structure docks, rubber fenders are installed on the docking components, and the size of the docking components can be adjusted to meet the docking requirements of large and small ships. For gravity docks, rubber fenders are often installed on the breastwork, which is a cast-in-place concrete structure. When considering the docking of small ships, due to the construction water level limit, the docking facilities (rubber fenders) need to be constructed underwater.

[0003] The traditional method for constructing underwater fender holes involves surveyors staking out the screw positioning plate locations and installing the positioning plates. A cross-shaped work frame is then fabricated from steel bars and securely hung on the dockside. A diver then operates a pneumatic rock drill from the frame while another diver holds the drill rod and drills the hole at the designated location. Once the designed depth is reached, the drill rod is removed and the hole is cleaned. Non-dispersible cement mortar is then injected into the hole to embed the underwater fender screws. Finally, the rubber fender is installed after the mortar reaches the required strength. This method is time-consuming and labor-intensive, and the quality of the underwater grouting cannot be guaranteed. Utility Model Content

[0028] Example

[0029] This embodiment provides a grouting device for installing underwater fender screws.

[0030] Figure 1 This is a side view of the grouting device for installing underwater fender screws of the present invention installed on the grouting chamber; Figure 2 This is a front view of the connecting plate installed on the perfusion chamber.

[0031] like Figures 1 to 2As shown in the figure, the grouting device for installing underwater fender screws described in this embodiment may include a grouting pipe 2 and a connecting plate 1. A feed port 11 is provided on the connecting plate 1, and the feed port 11 can pass through the connecting plate 1. A grouting cavity 5 is provided at the installation position of the fender screw 7 on the breast wall 6. The connecting plate 1 can be installed at the opening of the grouting cavity 5 to seal the opening of the grouting cavity 5; the outlet end of the grouting pipe 2 can be connected to the grouting cavity 5 through the feed port 11.

[0032] When using the grouting device of the present application, a grouting chamber 5 can be first opened at the installation position of the fender screw 7 on the underwater breast wall 6, the fender screw 7 can be installed in the grouting chamber 5, and then the connecting plate 1 can be installed at the opening of the grouting chamber 5 to seal the grouting chamber 5. The outlet end of the grouting pipe 2 can be extended underwater to communicate with the feed port 11 on the connecting plate 1, so that the grouting pipe 2 can be connected with the grouting chamber 5, and the inlet end of the grouting pipe 2 can be kept above the water surface. Non-dispersible cement mortar can be injected into the grouting pipe 2 on the shore, and the non-dispersible cement mortar can enter the grouting chamber 5 along the grouting pipe 2 through the feed port 11 to achieve pouring and complete the burial and fixation of the fender screw 7. Divers only need to be sent to install the connecting plate 1 and the grouting pipe 2 at low tide. There is no need to work underwater during the grouting process, which improves the efficiency of the grouting operation and ensures the quality of the grouting.

[0033] In this embodiment, an air vent 12 may also be provided on the connecting plate 1. When grouting is performed into the grouting cavity 5, the air or water remaining in the grouting cavity 5 can be discharged from the grouting cavity 5 through the air vent 12 on the connecting plate 1. When installing the connecting plate 1, the air vent 12 can be located above the feed port 11. During grouting, the non-dispersible cement mortar entering the grouting cavity 5 from the feed port 11 below can gradually fill the grouting cavity 5 from bottom to top. The air or water remaining in the grouting cavity 5 will be located above the non-dispersible cement mortar, and can be discharged from the air vent 12 located above the feed port 11 to the outside of the grouting cavity 5 as the non-dispersible cement mortar is gradually injected. In addition to reserving the air outlet 12 on the connecting plate 1, the length of the connecting plate 1 can also be prefabricated to be slightly smaller than the opening size of the perfusion chamber 5. When installing the connecting plate 1, a small gap can be left between the top of the connecting plate 1 and the top wall of the perfusion chamber 5 to serve as an exhaust port for the perfusion chamber 5, which can also achieve the purpose of exhaust. The present utility model does not specifically limit the exhaust structure.

[0034] In addition to being used to discharge air or water remaining in the grouting cavity 5, the air vent 12 can also be used to indicate that grouting is completed. When the non-dispersible cement mortar injected into the grouting cavity 5 gradually fills the grouting cavity 5 from bottom to top, it will eventually be discharged from the air vent 12. When non-dispersible cement mortar is observed to emerge from the air vent 12, it means that the non-dispersible cement mortar has completely filled the grouting cavity 5, indicating that the grouting operation is completed. At this time, the continued injection of the non-dispersible cement mortar can be stopped.

[0035] In this embodiment, a bolt embedded hole 13 is further opened on the connecting plate 1. The end of the fender screw 7 installed in the perfusion cavity 5 will extend from the opening of the perfusion cavity 5. Therefore, a bolt embedded hole 13 can be reserved at the corresponding position of the fender screw 7 on the connecting plate 1. When installing the connecting plate 1, the fender screw 7 can be passed through the bolt embedded hole 13, and there will be no interference between the connecting plate 1 and the fender screw 7. The fender screw 7 will not affect the installation of the connecting plate 1.

[0036] In this embodiment, a funnel 3 is provided at the inlet end of the grouting pipe 2, and the funnel 3 can be connected to the grouting pipe 2. When performing grouting operations, the pump pipe of the cement pump truck can be aligned with the funnel 3, and the non-dispersed cement mortar can be directly injected into the funnel 3, and then enter the grouting pipe 2 directly to the feed port 11, and finally enter the grouting cavity 5 to realize grouting; the funnel 3 can ensure to the greatest extent that the non-dispersed cement mortar flowing out of the pump pipe of the cement pump truck enters the grouting pipe 2, avoiding the loss and waste of non-dispersed cement mortar due to misalignment of the pump pipe and the grouting pipe 2.

[0037] Optionally, the outlet end of the funnel 3 is provided with a first external thread (not shown in the figure), and the inlet end of the grouting pipe 2 is provided with a first internal thread (not shown in the figure) that matches the first external thread, so that the funnel 3 can be screwed into the inlet end of the grouting pipe 2 and fixed. The funnel 3 can also be connected to the grouting pipe 2 through an interference fit, that is, the funnel 3 can be directly inserted into the grouting pipe 2 and fixed.

[0038] The present invention does not specifically limit the connection method between the funnel 3 and the grouting pipe 2.

[0039] Optionally, the connecting plate 1 may further be provided with a positioning hole 14. The positioning hole 14 is used to fasten the connecting plate 1 to the side wall (breast wall 6) of the perfusion cavity 5 when the connecting plate 1 is installed. For example, a fastener 4 may be passed through the positioning hole 14 for fixed connection, or glue may be injected into the positioning hole 14 to glue the connecting plate 1 to the side wall of the perfusion cavity 5.

[0040] Optionally, the grouting device for installing underwater fender screws described in this embodiment may further include a fastener 4, which can pass through the positioning hole 14 to connect the connecting plate 1 to the side wall of the grouting cavity 5. The fastener 4 can be specifically a fastening bolt, a screw, a threaded rod, etc., which is not specifically limited in the present invention.

[0041] Optionally, the caliber of the inlet end of the grouting pipe 2 is larger than the caliber of the outlet end of the grouting pipe 2. A slightly larger caliber of the inlet end of the grouting pipe 2 than that of the outlet end can be more convenient for connecting with the funnel 3, and is also more conducive to generating sufficient grouting pressure without dispersing the cement mortar settling in the grouting pipe 2.

[0042] Optionally, the outlet end of the grouting pipe 2 is provided with a movable screw sleeve (not shown in the figure), the movable screw sleeve is provided with a second external thread (not shown in the figure), and the feed port 11 is provided with a second internal thread (not shown in the figure) that cooperates with the second external thread. The movable screw sleeve can be screwed into the feed port 11 to fix the grouting pipe 2. The connection between the grouting pipe 2 and the feed port 11 can be threaded through a movable screw sleeve, or can be connected by an interference fit between the grouting pipe 2 and the feed port 11, that is, the grouting pipe 2 can be directly inserted into the feed port 11 and fixed. The present utility model does not specifically limit the connection method between the grouting pipe 2 and the feed port 11.

[0043] Optionally, the material of the grouting pipe 2 can be a flexible material or a rigid material; the present invention does not limit the specific material of the grouting pipe 2.

[0044] To sum up, by using the grouting device of the present application, a grouting chamber can be first opened at the installation position of the underwater fender screw, the fender screw can be installed in the grouting chamber, and then the connecting plate can be installed at the opening of the grouting chamber to seal the grouting chamber. The outlet end of the grouting pipe can be extended into the water to connect with the feed port on the connecting plate, so that the grouting pipe can be connected with the grouting chamber, and the inlet end of the grouting pipe can be kept above the water surface. Non-dispersible cement mortar can be injected into the grouting pipe on the shore, and the non-dispersible cement mortar can enter the grouting chamber through the feed port along the grouting pipe to achieve pouring and complete the burial and fixation of the fender screw. Divers only need to install the connecting plate and grouting pipe at low tide. There is no need to work underwater during the grouting process, which improves the efficiency of the grouting operation and ensures the quality of grouting.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
