Description

Technical Field

[0001] The utility model relates to the technical field of dock repair, and more specifically, to a rapid repair structure for a dock tidal zone without underwater operation. Background Art

[0002] Due to the natural erosion caused by periodic changes in water levels and the external forces of ship collisions, durability defects in the tidal zone of a dock are the most prominent and easily discovered problem among the many structures in the dock, and have always been a key difficulty in dock maintenance projects. Conventional methods for repairing tidal zones of docks include surface defect repair and demolition and reconstruction. Surface defect repair can only restore the appearance and slow down the rate of erosion in a short period of time, and is suitable for shallow defects. Demolition and reconstruction can fundamentally solve the problem and is suitable for docks with more serious defects, but it requires underwater operations, is costly, has a long cycle, and has an impact on dock operations. In dock maintenance projects, it is necessary to develop a rapid repair device to solve the problem of repairing defects in the tidal zone of the dock. Utility Model Content

[0003] An object of the present invention is to solve at least the above problems and to provide at least the advantages to be described below.

[0004] In order to achieve these purposes and other advantages according to the present invention, a rapid repair structure for a tidal zone of a dock without underwater operation is provided, comprising:

[0005] A plurality of embedded steel bars are evenly distributed on the pier breast wall, and a steel mesh is hung on the embedded steel bars;

[0006] A precast panel is parallel to the wharf breast wall and is arranged at a certain distance from the wharf breast wall; the precast panel comprises a plurality of precast blocks connected in sequence; concrete is poured between the precast panel and the wharf breast wall to form an integrated layer;

[0007] The embedded steel bars, the steel mesh, the prefabricated panels and the integrated layer are all arranged above the designed low water level of the wharf.

[0008] Preferably, the prefabricated block comprises a prefabricated block body, and the prefabricated block body extends from one side away from the wharf breast wall to both ends to form flange portions, and the flange portions of two adjacent prefabricated block bodies are affixed.

[0009] Preferably, a plurality of U-shaped connecting ribs are arranged at intervals on both sides of the prefabricated block body along its height direction, the connecting ribs on both sides of the prefabricated block body are staggered, and the open ends are inserted into the prefabricated block body; the connecting ribs extend out of the flange portion on the same side.

[0010] Preferably, the connecting rib extends 5 to 10 cm beyond the flange of the flange portion on the same side.

[0011] Preferably, when two adjacent prefabricated block bodies are butt-jointed, their flange portions are fitted together to form a casting space, and the connecting bars of the two prefabricated block bodies in the casting space are staggered in the height direction, and pin steel bars are vertically inserted, and the pin steel bars pass through the connecting bars in the casting space in sequence.

[0012] Preferably, the prefabricated block is provided with a plurality of cavities, and concrete is poured into the cavities simultaneously with pouring the integrated layer.

[0024] like Figure 1 As shown, the utility model provides a rapid repair structure for a tidal area of ​​a dock without underwater operation, comprising:

[0025] A plurality of embedded steel bars 1 are evenly distributed on the pier breast wall, and a steel mesh 2 is hung on the embedded steel bars 1;

[0026] A precast panel is parallel to the wharf breast wall and is arranged at a certain distance from the wharf breast wall; the precast panel comprises a plurality of precast blocks 3 connected in sequence; concrete is poured between the precast panel 3 and the wharf breast wall to form an integrated layer 4;

[0027] The embedded steel bars 1, the steel mesh 2, the prefabricated panels 3 and the integrated layer 4 are all arranged above the designed low water level of the wharf.

[0028] In this technical solution, the precast panels are hung above the designed low water level of the wharf, and the two are connected as one by the embedded steel bars 1, the steel mesh 2 and the integrated layer 4. During construction, the wharf breast wall is first surface treated or partially demolished, the steel bars are embedded and the steel mesh 2 is hung, and then the precast panels are hoisted and hung on the outside of the wharf breast wall, and the cast-in-place integrated layer 4 is constructed between the breast wall and the precast blocks 3. The steel mesh 2 is used to prevent the integrated layer 4 from cracking. The integrated layer 4 is constructed by cast-in-place concrete using a hanging formwork, avoiding underwater operations. The precast panels are connected by a plurality of the precast blocks 3, and a large amount of reinforced concrete engineering is completed on land, which improves speed and quality and reduces costs.

[0029] In another technical solution, Figure 2 and Figure 3 As shown, the prefabricated block 3 includes a prefabricated block body 31. The prefabricated block body 31 extends from one side of the prefabricated block body 31 away from the pier breast wall to form flanges 33 at both ends. The flanges 33 of two adjacent prefabricated block bodies 31 are affixed. The flanges 33 can serve as side forms when pouring the integrated layer 4.

[0030] Furthermore, multiple U-shaped connecting ribs 32 are spaced apart along the height of the prefabricated block body 31 on both sides. The connecting ribs 32 on both sides of the prefabricated block body 31 are staggered, with their open ends inserted into the prefabricated block body 31. The connecting ribs 32 extend beyond the flange on the same side. Preferably, the connecting ribs extend 5-10 cm beyond the edge of the flange on the same side.

[0031] When two adjacent prefabricated block bodies 31 are butt-jointed, their flange portions 33 are fitted together to form a casting space, in which the connecting bars of the two prefabricated block bodies in the casting space are staggered in the height direction, and latch steel bars 5 are vertically inserted, which pass through the connecting bars 32 in the casting space in sequence.

[0032] The connecting ribs 32 are staggered on both sides of the prefabricated block body 31 to avoid interference between the connecting ribs 32 on the butt joint side when the two prefabricated blocks 3 are spliced, and can be staggered to extend into the casting space of the adjacent prefabricated blocks 3. The height difference of the staggered connecting ribs 32 on both sides of the prefabricated block 3 is 10~20cm. The latch steel bars 5 are vertically inserted into the staggered connecting ribs 32 between the two adjacent prefabricated blocks 3, and after pouring concrete, the prefabricated blocks 3 are horizontally connected as a whole. Multiple latch steel bars 5 can be set between the two adjacent prefabricated blocks 3. When pouring the integrated layer 4, the pouring space is poured simultaneously to increase the integrity of the entire rapid repair structure of the wharf tidal area.

[0033] In another technical solution, the prefabricated block 3 is provided with a plurality of cavities 34, and concrete is poured into the cavities 34 simultaneously with pouring the integrated layer. The prefabricated block 3 is a hollow prefabricated block, which can reduce the weight of the hoisting. Figure 2 As shown, the cavity 34 is cylindrical.

[0034] In another technical solution, the distance between the prefabricated panel and the wharf breast wall is 10-20 cm, which is used for the later cast-in-situ of the integrated layer.

[0035] In another technical solution, the planted rebar 1, the steel mesh 2, the connecting rebar 32, and the pinning rebar 5 are all epoxy-coated steel bars. Alternatively, the planted rebar 1, the steel mesh 2, the connecting rebar 32, and the pinning rebar 5 are all coated with a galvanized layer. The internal reinforcement of the tidal zone rapid repair structure is galvanized or epoxy-coated to improve structural durability.

[0036] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
