Description

Technical Field

[0001] This utility model belongs to the field of underwater repair construction technology, specifically relating to a template device for underwater structure enlargement repair. Background Technology

[0002] Underwater repair construction is particularly important in industries such as port terminals, bridge engineering, and hydropower stations. For example, cast-in-place piles are a primary foundation structure in ports and wharves. Because they are constantly submerged, especially in the open sea, they face harsh conditions and are subject to erosion and damage from ocean currents, typhoons, and marine life year-round. Therefore, regular repairs are necessary for damaged sections. Similarly, bridge piers exposed to underwater erosion also require regular maintenance. Traditionally, underwater repair construction involves using custom-made steel formwork to enclose the structure to be repaired and then pouring underwater-grade concrete into the formwork. However, most existing custom-made steel formwork requires underwater welding, resulting in difficult and inefficient assembly. Therefore, researching an underwater formwork that is lightweight, easy to load and unload, and offers high construction efficiency is of great significance. Utility Model Content

[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0030] See Figures 1-5 This embodiment discloses a template device for underwater structure enlargement repair, which can be specifically applied to underwater pile foundation repair construction and bridge pier construction in dock engineering. Figures 1-5 This illustration demonstrates the application of the template device of this embodiment in pile foundation repair construction. The template device of this embodiment includes a water bladder 1 and multiple fall arresting ropes 7. The water bladder 1 serves as the main structure of the template device. The multiple fall arresting ropes 7 are arranged at intervals along the width of the water bladder 1. One end of each fall arresting rope 7 is fixed to the water bladder 1, and the other end extends upwards beyond the water bladder 1 and is used to fix it to the underwater structure to be repaired. The water bladder 1 has a filling port 2 and a pouring port 3. Both the filling port 2 and the pouring port 3 are equipped with switches for opening or closing the openings. These switches can be valves or other structures. The filling port 2 communicates with the inner cavity of the water bladder 1, allowing filling or discharging of a filling medium to inflate or compress the water bladder 1. The pouring port 3 passes through both the inner and outer sides of the water bladder 1, allowing the pouring of repair medium into the inner side of the water bladder 1.

[0031] Furthermore, this embodiment also includes a detachable locking structure for keeping the water bladder 1 surrounded by an annular closed structure around the underwater structure to be repaired; the detachable locking structure can be on the water bladder 1 or an external structure.

[0032] In this embodiment, a first water-stop strip 9 is provided on the bottom inner side of the water bladder 1. When the water bladder 1 surrounds the underwater structure to be repaired in a closed annular structure, the first water-stop strip 9 seals the gap between the bottom of the water bladder 1 and the underwater structure to be repaired. A second water-stop strip 10 is provided on the top inner side of the water bladder 1. The second water-stop strip 10 is shorter than the length of the water bladder 1. When the water bladder 1 surrounds the underwater structure to be repaired in a closed annular structure, the second water-stop strip 10 is located in a ring in the gap between the top inner side of the water bladder 1 and the underwater structure to be repaired, leaving a drain outlet 11. Specifically, the water bladder 1 in this embodiment is rectangular so that it can be bent and closed to form a ring structure surrounding the underwater structure to be repaired. The second water-stop strip 10 in this embodiment can be set to be 10cm shorter than the length of the water bladder 1, so that a drain outlet 11 can be formed when the water bladder 1 bends to form a ring structure. When pouring into the inside of the water bladder 1, the water in the cavity between the water bladder 1 and the underwater structure to be repaired can be discharged through the drain outlet 11.

[0033] Multiple magnetic attractors 8 are provided on both ends of the water bladder 1. When the water bladder 1 is bent to form a ring structure, the magnetic attractors 8 on both ends of the water bladder 1 attract each other to ensure that the two ends of the water bladder 1 are closed. In this embodiment, the multiple magnetic attractors 8 are arranged at intervals along the height direction of the water bladder 1. Furthermore, the magnetic attractors 8 in this embodiment can be magnetic adhesives, whose sheet-like structure allows the two ends of the water bladder 1 to attract each other better and close. The magnetic attractors 8 can refer to magnets in the prior art, and the magnetic attractors 8 on both sides can attract each other through magnetic force. In addition, the use of magnetic attraction also facilitates the closing and opening of the two ends of the water bladder 1, improving construction efficiency.

[0034] Furthermore, the water bladder 1 has multiple transverse ribs 6 on its outer side, which extend along the length of the water bladder 1. The two ends of the transverse ribs 6 are detachably connected by a detachable locking structure; when the water bladder 1 is bent to form a ring structure, the two ends of the transverse ribs 6 are connected to each other.

[0035] Furthermore, the transverse ribs 6 in this embodiment can adopt a strip structure so that they can bend or fold with the water bladder 1. Of course, the transverse ribs 6 in this embodiment can also be made of a material with a certain strength and deformation capacity to ensure the strength and rigidity of the water bladder 1. The detachable locking structure in this embodiment can be a snap-fit ​​structure, which can refer to the prior art. Generally, it can include a snap-fit ​​element and a slot, which are respectively set at both ends of the transverse ribs 6. The fixing effect is achieved by the snap-fit ​​element and the slot engaging and locking each other, while it can also be disassembled and released, which is convenient to operate. In the snap-fit ​​state, the water bladder 1 can be more stably kept in a ring shape to surround the underwater structure to be repaired, so as to carry out the pouring repair construction.

[0036] Of course, in this embodiment, in addition to the snap fasteners between the transverse ribs 6, other additional fixing methods can be used to fix the water bladder 1 in an annular state.

[0037] Furthermore, the water bladder 1 has multiple vertical reinforcing members 5 on its outer side. These vertical reinforcing members 5 extend along the height direction of the water bladder 1 and are arranged along its width direction. To facilitate the assembly, disassembly, and storage of the vertical reinforcing members 5 and the water bladder 1, multiple vertically extending mounting bags 4 are provided on the outer side of the water bladder 1, and each vertical reinforcing member 5 is inserted into a corresponding mounting bag 4. Specifically, the vertical reinforcing members 5 in this embodiment can be steel pipes, reinforcing bars, etc. When the water bladder 1 is filled with a filling medium and bent into a ring structure to surround the underwater structure to be repaired, the vertical reinforcing members 5 are inserted into the mounting bags 4, thereby further improving the rigidity of the water bladder 1 and preventing its deformation.

[0038] The method of using the template device for underwater structure enlargement and repair in this embodiment is as follows:

[0039] S1: Inflate water bladder 1 with water and pressurize it before dragging it underwater.

[0040] S2: Arrange the water bladder 1 in a ring along the underwater structure (such as a pile foundation) that needs to be repaired, so that the magnetic suction parts 8 on the left and right sides of the water bladder 1 attract each other to form a ring.

[0041] S3: The two ends of the transverse rib 6 of the water bladder 1 are connected by a detachable locking structure, so that the transverse rib 6 forms a ring to further fix the ring structure of the water bladder 1.

[0042] S4: Fix one end of the fall arrest rope 7 to the pile foundation and tighten it.

[0043] S5: Insert the steel pipe into the steel pipe strip.

[0044] S6: Inflate and pressurize the water bladder 1 again until the pressure inside the water bladder 1 reaches the design requirements.

[0045] S7: Connect the slurry outlet of the concrete pump hose to the pouring port 3 on the water bladder 1.

[0046] S8: Start the concrete pump to begin pouring concrete. Stop pouring when concrete slurry flows out from the drainage outlet 11 reserved on the second waterstop strip 10 at the top of the water bag 1.

[0047] S9: Concrete curing.

[0048] S10: Remove the formwork device.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
