Description

Technical Field

[0001] The utility model belongs to the technical field of suspension bridges, and in particular relates to an anchor surface waterproof structure layer. Background Art

[0002] In long-span suspension bridges, gravity anchors are usually used as the load-bearing structure of the main cable. Its characteristic is that the main cable is dispersed into several strands at the anchor by a cable-scattering device, and each strand is anchored in the anchor by a steel tie rod. In order to prevent water seepage in the anchor chamber from affecting the durability of the anchor and the main cable, waterproof concrete is generally used during anchor construction. However, due to the existence of construction joints and the uncertainty of construction quality, there is often local water seepage in the anchor during operation. Therefore, it is necessary to add a surface waterproof structure layer on the basis of the original structure. The waterproof structure layer in the existing technology has the problem of easy detachment and cannot achieve a good waterproof effect. Utility Model Content

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Example 1

[0027] A leveling layer 2 is laid on the surface of the anchor 1;

[0028] A waterproof layer 3 is laid on the surface of the leveling layer 2;

[0029] A protective layer 4 is laid on the surface of the waterproof layer 3;

[0030] The connection reinforcement layer 5 is arranged between the protection layer 4 and the waterproof layer 3 .

[0031] Further optimizing the solution, the connection reinforcement layer 5 includes:

[0032] There are multiple conical structures, the bottom surfaces of the conical structures are fixedly connected to the surface of the waterproof layer 3, and the multiple conical structures are distributed in an array.

[0033] According to a further optimization scheme, the cone diameter of the cone structure is 1 cm to 2 cm, the height of the cone structure is not more than 2 times the cone diameter, and the axial distance between two adjacent cone structures is not more than 5 cm.

[0037] Specifically, the leveling layer 2 is preferably a cement mortar layer, the ratio of water to cement is not greater than 1:1, and the thickness is not less than 1 cm;

[0038] The waterproof layer 3 is directly applied to the outer surface of the leveling layer 2, using existing waterproof coatings, with a thickness of not less than 2mm;

[0041] Construction method: Apply the leveling layer 2 directly on the surface of the anchor 1. After the leveling layer 2 reaches the set strength, the surface of the leveling layer 2 is roughened with a roughening depth of 2mm to 5mm. Then, the waterproof material is applied to the surface of the leveling layer 2 in layers for multiple times to form a waterproof layer 3. The number of layers of the waterproof layer 3 is not less than 3 times. The next layer can be applied only after each layer is applied and dried. The thickness of the waterproof layer 3 is not less than 2mm and matches the roughening depth of the leveling layer. Apply the material of the conical structure evenly on the roughening paddle, and pat the roughening paddle on the surface of the waterproof layer 3 with force. After the roughening paddle is removed, a multi-point conical structure will be formed on the surface of the waterproof layer 3. Paste a coarse mesh linen cloth with an aperture of 2mm×2mm at the positive and negative corners of the anchor 1. After the conical structure is dried and solidified, apply a protective layer 4 with a thickness of 2cm to 3cm.
