Description

Technical Field

[0001] This utility model relates to an expansion joint structure suitable for frame-type dikes, applicable to the field of expansion joints for frame-type dikes in hydraulic engineering, port engineering, and marine engineering, and mainly used in the deformation design between frame-type dike structures in coastal water conservancy, port and shipping, and marine industries. Background Technology

[0002] In the design of frame-type concrete dikes and other structural designs, to avoid expansion and contraction deformation caused by changes in temperature and humidity, as well as displacement due to ground settlement and earthquakes, expansion joints are added to the frame-type dike structure to divide it into several independent units. For frame-type dike structures, because the lower part of the structure is hollow, positive and negative pressures are formed under wave action, and the structure is subjected to wave impact. Conventional expansion joint structures are easily damaged because they cannot protect the waterproofing material or reduce wave energy, leading to seawater erosion and damage to the dike structure. Summary of the Invention

[0003] In order to overcome the shortcomings of existing technologies, this utility model provides a deformation joint structure suitable for frame-type dikes, which has the advantages of pressure relief, energy dissipation and adaptability to structural deformation.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] An expansion joint structure suitable for frame-type dikes is provided. The expansion joint structure is set at the joint between a first rigid structure and a second rigid structure. The expansion joint structure includes three water-stopping components, which are arranged vertically along the joint and embedded in the rigid structures on both sides. The three water-stopping components are designated as the first, second, and third water-stopping components, and are arranged from top to bottom at the joint. The first water-stopping component is fully distributed along the joint direction. The second and third water-stopping components are staggered and spaced along the joint direction.

[0006] Preferably, the three water-stopping components are embedded in the rigid structures on both sides of the joint, perpendicular to the direction of the gap, and are in direct contact with the rigid structures.

[0007] Furthermore, the three water-stopping components are arranged vertically separately, with the second and third water-stopping components overlapping at their ends.

[0008] Furthermore, the three water-stopping components are made of water-stopping materials with certain strength and ductility.

[0009] Preferably, the three water-stopping components are copper sheet water-stops.

[0010] Furthermore, the first rigid structure and the second rigid structure are concrete or reinforced concrete structures. These rigid structures will expand and contract due to changes in factors such as temperature and humidity, and will also experience displacement due to ground subsidence and earthquakes.

[0011] The technical concept of this utility model is as follows: the first water-stopping component is used to adapt to structural deformation and prevent water from passing through the gap; the second and third water-stopping components are used to adapt to structural deformation and shorten the gap length to reduce the flow rate and impact force of waves, and play a role in relieving pressure and dissipating energy when subjected to high-pressure water flow impact or suction, thereby effectively protecting the first water-stopping component.

[0012] The main benefits of this invention are: effectively reducing the impact of water in the lower part of the frame-type dike on the deformation joint and extending the service life of the dike. Attached Figure Description
