fig. 3 is an enlarged view of the region B in fig. 1.
Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below by combining the specific drawings.
Referring to fig. 1 to 3, the wind power foundation anchor bolt cage waterproof sealing structure provided by the invention comprises a grouting layer 100, a foundation upper flange 200, a tower bottom flange 300 and a plurality of anchor bolt rods 400.
A protective cap 410 is provided at the head of each anchor rod 400, and the protective cap 410 is detachably connected to the head of the anchor rod 400 by means of a screw thread for protecting the anchor rod 400.
The protective cap 410 is filled with weather-resistant silicone 411, so that the anchor rod 400 is prevented from being corroded by water even if the head of the anchor rod 400 is submerged in water.
In addition, an O-shaped gasket 412 is sleeved on the lower portion of the protective cap 410, and the O-shaped gasket 412 is fixedly connected with the tower bottom flange 300 through a sealant 413, so that the sealing performance of the mounted protective cap 410 can be improved, and water and silt can be prevented from entering the protective cap 410.
On the basis, the upper surface of flange 200 is equipped with inside and outside two rings of fluting 210, inside and outside ring fluting is located the outside of two rows of anchor bolt holes of upper flange respectively, be equipped with rubber seal 211 in every cell body 210, cell body 210 width is 10mm, the degree of depth is 6mm, rubber seal 211's width is 8.5mm, highly be 8mm, when flange 200 contacts on tower section of thick bamboo bottom flange 300 and the basis, can compress tightly rubber seal 211, thereby can ensure inside the unable tower section of thick bamboo that gets into of fan operation in-process normal water, further improve waterproof performance.
This application still can include a sealed barrel 500, sealed barrel 500 sets up on grout blanket 100, and sealed barrel 500's outer wall and grout blanket 100 parallel and level, sealed barrel 500's inner wall respectively with the outer surface sealing connection of flange 200 and tower section of thick bamboo bottom flange 300 on the basis, like this through setting up sealed barrel 500, can be on the basis flange 200 and tower section of thick bamboo bottom flange 300 outer formation sealing wall, can ensure inside the unable tower section of thick bamboo that gets into of fan operation in-process normal water, further improve the leakproofness.
The sealing cylinder 500 specifically includes a circumferentially enclosed fence 510, the fence 510 is flush with the grouting layer 100, a sealant 520 is filled in the fence, and the outer surfaces of the foundation upper flange 200 and the tower bottom flange 300 are respectively in close contact with the sealant 520.
