Example Embodiment

[0036] The manufacturing steps of the water deflector 12 in the first embodiment are as follows:

[0037] Step 1. Manufacture the baffle 13:

[0038] A1. At a distance of 45 mm from the outer wall of the foundation ring 1, an annular groove 17 with a width of 20 mm is opened. The depth of the annular groove 17 is determined according to the surface structure of the foundation cap 2. If there is no secondary plastering layer on the surface of the foundation cap 2, the annular groove 17 The depth is 20 mm; if there is a secondary plastering layer on the surface of the foundation cap 2, the depth of the annular groove 17 should reach 20 mm below the surface of the primary cast concrete. A water drill is required for grooving. Drilling with an electric hammer is strictly prohibited to avoid damage to nearby concrete.

[0039] A2. In the completed annular groove 17, drill a hole with a diameter of 20 mm with a water drill every 50 cm, and a depth of 100 mm, to clean the hole.

[0040] A3....

Example Embodiment

[0060] The construction steps of the second embodiment are as follows:

[0061] C1. The opening width of the upper surface of the foundation cap 2 is 75 mm, and the depth is 20 mm. The annular groove 29 is determined according to the surface structure of the foundation cap 2. If there is no secondary plastering layer on the surface of the foundation cap 2 , The depth of the annular groove 29 is 20 mm. If the surface of the foundation cap 2 has a secondary plastering layer, the depth of the annular groove 29 reaches 20 mm below the surface of the primary cast concrete. The bottom of the annular groove 29 should be flat to avoid damaging the nearby concrete when slotting.

[0062] C2. Drill a hole with a diameter of 12 mm in the annular groove 29 according to the position of the hole on the horizontal side 242 of the L-shaped rubber plate 24, and install a stainless steel expansion screw 25 in the hole.

[0063] C3. Apply 3 mm thick structural glue evenly on the bottom of the annular...

Abstract

The invention relates to a method for improving the basic waterproof performance of a wind generating set. A waterproof structure is arranged on the periphery of a base ring. A fastening device is arranged on the waterproof structure. The waterproof structure is compressed by the fastening device and is sealed and fixed to the outer circumferential surface of the base ring, so that the waterproofstructure is prevented from sliding downwards under the action of gravity and destroying the waterproof performance, and the waterproof performance between the waterproof structure and the base ring is ensured. Meanwhile, the waterproof structure is arranged in an annular groove in the surface of a base bearing platform, and the gap between the waterproof structure and the basic bearing platform is filled with a sealing material, so that rainwater intrusion into the gap between the base ring and the base bearing platform along the surface of the base bearing platform is further avoided, and the basic waterproof performance of the wind generating set can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of new energy power generation construction, and in particular relates to a method for improving the waterproof performance of the foundation of a wind power generating set. Background technique [0002] Wind power generation is an important part of the country's new energy construction, and onshore wind farms are one of the main forms of wind power generation. At present, the connection between the tower of high-power wind turbines and the foundation of the wind turbine is usually the way of the foundation ring, and the foundation ring is integrated with the reinforced concrete pouring. Since the tower is always in a state of vibration during the operation of the wind turbine, it is poured on the outer wall of the foundation ring. The sealant with the concrete is constantly torn and loses its waterproof function, causing rainwater to enter the stress area of ​​the concrete foundation, reducing the friction ...
