Abstract
The utility model relates to a force-transferring waterproof pad layer for a hydropower station, which solves the hidden danger of instable performance caused as the existing force-transferring pad layer among the pressure water-guiding steel pipe, the steel volute and the wrapped reinforced concrete of the hydropower station adsorbs percolation water. The force-transferring waterproof pad layer comprises a force-transferring pad layer and a waterproof layer, the force-transferring pad layer is formed by splicing a plurality of polyurethane cork pad layers, and the waterproof layer is the waterproof material coated on the surfaces of the polyurethane cork pad layers. The force-transferring waterproof pad layer has the advantages of force transferring, water proofing, simple structure and convenient construction.
Description
Technical field
The utility model relates to the power station with penstock and steel spiral case outsourcing bed course.
Background technology
In the power station, high-velocity flow flows to hydrogenerator from eminence downwards through the pressure diversion steel pipe, and strong current impacts steel pipe and hydrogenerator steel spiral case.The outsourcing bed course plays a part quantitative adjusting steel pipe, steel spiral case and encased steel reinforced concrete and shares the internal water pressure ratio.The physical mechanics property stabilizability direct relation of its course the size that steel pipe, steel spiral case and encased steel reinforced concrete are shared the internal water pressure ratio.For preventing that course from absorbing the water that oozes out in the concrete and influencing its stable mechanical property, must take measures to solve the water proof problem of hydropower station pressure diversion steel pipe and steel spiral case usefulness power transmission bed course.
The utility model content
The utility model purpose provides a kind of power station power transmission water proof bed course, and it has solved the unstable properties hidden danger that the power transmission bed course causes because of absorption percolating water between existing hydropower station pressure diversion steel pipe, steel spiral case and the encased steel reinforced concrete.
Technical solution of the present utility model is:
A kind of power station power transmission water proof bed course, its special character is: comprise power transmission bed course and water barrier; Described power transmission bed course is put together by many flexible polyurethane headblock layers, and described water barrier is the waterproofing materials that is coated in flexible polyurethane headblock laminar surface.
Above-mentioned waterproofing materials for the time of refer to doing be not more than 50 seconds can be under pressure and its tensile strength greater than the elastic body of power transmission bed course tensile strength.
Above-mentioned elastic body is a polyurethane.
Above-mentioned elastic body is a polyureas.
Above-mentioned elastic body is a polyurethane-urea.
The thickness of above-mentioned power transmission bed course is 5～50mm, and the thickness of described water barrier is 0.1～1.5mm.
Above-mentioned flexible polyurethane headblock layer is a rectangle, and its length is 500～5000mm, and its width is 500～1300mm.
Above-mentioned flexible polyurethane headblock layer is a rectangle, and its length is 950mm, and its width is 640mm.
Technique effect of the present utility model is:
1, power transmission.The power transmission bed course is a flexible polyurethane headblock layer, can produce to be similar to linear deformation under the effect of external force, can obtain the power transmission effect.
2, water proof.The water barrier of material has certain impermeable role.
3, simple in structure, easy construction.The utility model only needs in advance waterproofing materials to be coated on flexible polyurethane headblock layer and the surface that concrete contacts, goes on-the-spot sticking construction to get final product then.

Fig. 1 is the utility model sectional drawing.
The 1-current, 2-steel pipe, 3-water barrier, 4-power transmission bed course, 41-flexible polyurethane headblock layer, 5-steel concrete.
The specific embodiment
The utility model power station comprises the power transmission bed course with power transmission water proof bed course and is coated on the water barrier of power transmission bed course lateral surface.The power transmission bed course is put together by many rectangle polyurethane corks, and its length is 500～5000mm, and width is 500～1300mm, and thickness is 5～50mm.Water barrier is the waterproofing materials that is coated in the cork pad laminar surface, waterproofing materials for the time of refer to doing be not more than 50 seconds can be under pressure and its tensile strength greater than the elastic body of power transmission layer tensile strength.This waterproofing materials optimization polyurethane elastic body, polyurea elastomer and polyurethane-urea elastomer, polyurethane-urea claims polyurethane (urea) or heterozygosis polyureas again.Waterproofing materials thickness is 0.1～1.5mm.
The mode that the utility model adopts power transmission bed course, water barrier to combine reaches the purpose of power transmission water proof.It is for anti-sealing enters flexible polyurethane headblock layer inside the mechanical property and the physicochemical property of flexible polyurethane headblock layer to be changed that water barrier is set.In addition, if it is more to enter the water of flexible polyurethane headblock layer, the hydraulic pressure that can make the cork bed course transmit from inside to outside obviously increases, and can destroy the power transmission effect of power transmission bed course like this.Have, water barrier can reduce the frictional force between flexible polyurethane headblock layer and the concrete again.
