Description

Technical Field

[0001] The invention belongs to the technical field of civil engineering, and in particular relates to an anti-seepage device for different forms of revetment interfaces and a use method thereof. Background Art

[0002] The revetment is a type of retaining wall, which is a retaining wall facing the water. It has three functions: 1. Supporting the soil behind the wall; 2. Protecting the slope from being eroded by the water; 3. The high and low twists and turns of the revetment make the water more varied and improve the artistry of the garden.

[0003] Retaining walls are structures that prevent soil slopes from collapsing and withstand lateral pressure. They are a common municipal engineering project in gardens. They are widely used in gardens for house foundations, embankments, road cutting slopes, bridge pedestals, waterside pavilions, rockery, basements and other construction projects. They are especially common in mountainous cities with large terrain changes. Retaining walls are often built with materials such as bricks, concrete, and reinforced concrete. The design of retaining walls must first consider determining the nature, size, direction and point of action of the lateral earth pressure acting on the back of the wall to meet functional requirements.

[0004] During the revetment construction, different construction sections use different materials for revetment according to the design and geological conditions. At the same time, for waterproofing, the revetment is generally composed of 4 layers, the innermost layer is the structure, and the modified asphalt membrane waterproof additional layer, modified asphalt membrane waterproof layer and mortar protective layer are arranged in order. When the inner structural layer at the junction of the revetment is made of different materials, the different thermal expansion coefficients of the two materials will cause cracks in the later use process, destroying the stability of the revetment waterproof layer, and sometimes causing serious leakage problems.

[0034] In the figure: DETAILED DESCRIPTION

[0035] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] This embodiment provides an anti-seepage device for different types of revetment interfaces, such as Figure 1-4 As shown, it is used to be set at the revetment interface 10, and the revetment interface 10 includes two structures of revetments, brick revetments 11 and concrete revetments 12; the anti-seepage device includes at least a base 20 and the width of the base 20 spans the revetment interface 10, and the base 20 includes a first side plate 21, a second side plate 22, a connecting plate 23 and a top plate 24, wherein the first side plate 21 and the second side plate 22 are close to both sides of the outer wall of the revetment interface 10, and play a role in preventing the waterproof layer from breaking along with the internal structural layer. The first side plate 21 and the second side plate 22 each include a fixed end and a free end, and the fixed ends of the first side plate 21 and the second side plate 22 are respectively vertically fixedly connected to the two opposite edges of the top plate 24, that is, the top plate 24 connects the first side plate 21 and the second side plate 22 to form a "J"-shaped structure with an opening at the lower end, or an integral steel plate can be bent to make a corresponding structure to form a "J"-shaped structure, and its top plate 24 mainly plays the role of connecting the first side plate 21 and the second side plate 22. The connecting plate 23 is placed between the first side plate 21 and the second side plate 22, preferably in the middle, and is vertically fixedly connected to the top plate 24, that is, the first side plate 21, the top plate 24 and the second side plate 22 are connected in sequence and placed on the outer wall surface of the revetment interface 10 and are arranged closely to the outer wall of the revetment interface 10; the connecting plate 23 is placed in a groove reserved in the wall of the brick revetment 11 in the revetment interface 10 and is arranged across the width of the revetment interface 10. The connecting plate 23 mainly connects the wall of the brick revetment 11 in the revetment interface 10 with the base 20, so that the cross section formed by the first side plate 21, the second side plate 22, the connecting plate 23 and the top plate 24 constitutes a stable anti-seepage protection structure in the shape of an inverted "mountain", that is, it constitutes an integral anti-seepage device body of the revetment interface 10.

[0037] In order to further make the base 20 fit the bottom foundation of the revetment interface 10, the bottom of the first side plate 21 and the second side plate 22 are processed with R50mm arc angle, and the inner corner of the wall of the brick revetment 11 is also processed with R50mm arc angle in a matching manner.

[0038] In addition, the first side panel 21 and the second side panel 22 can be set to different heights according to different terrains. When the heights of both sides of the revetment interface 10 are inconsistent, the first side panel 21 and the second side panel 22 can adopt inconsistent heights to match the two sides of the revetment interface 10; when the heights of both sides of the revetment interface 10 are consistent, the two side panels of the first side panel 21 and the second side panel 22 in the base 20 of the anti-seepage device adopt a height consistency, which can more effectively protect the waterproof layer and prevent penetration.

[0039] The height of the middle connecting plate 23 can be determined according to the actual construction conditions. Preferably, the height of the connecting plate 23 is consistent with the wall height of the brick revetment 11, and can be completely embedded in the wall of the brick revetment 11 to enhance stability. Of course, it can also be shorter than the wall height of the brick revetment 11, but it should not be less than 1 / 3 of the wall height.

[0040] In this embodiment, the first side plate 21, the second side plate 22, the top plate 24, and the connecting plate 23 are all made by welding galvanized steel plates with a thickness of 3 mm and a width of 300 mm.

[0041] In order to further ensure the stability of the installation of the base 20, the first side plate 21, the second side plate 22, and the end of the connecting plate 23 close to the bottom of the brick revetment 10 are welded together with a galvanized steel plate 25, and the thickness of the galvanized steel plate 25 is also 3 mm.
