In the engineerings such as road construction, irrigation, municipal drainage, it is often necessary to build different types of water culvert excessively, commonly use
Water culvert of crossing be mostly masonry, concrete structure, difficulty of construction is high, and speed of application is slow.In recent years, with corrugated steel pipe technology
Develop, gradually adopt corrugated steel pipe to build culvert in engineering, construction is fast, and cost is low, and use range is wide, due to steel corrugated culvert pipe
Inner surface is waves structure, and current, sandstone wash away for a long time to ttom of pipe in drainage procedure, causes pipe surface at water to corrode
Seriously, the anticorrosive coat of corrugated steel pipe is destroyed, and influences culvert whole service life.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of protection against erosion steel plate knot of Performance Test of Corrugated Steel Culvert bottom surface
Structure, this protection against erosion steel plate structure can prevent Performance Test of Corrugated Steel Culvert bottom surface from being washed away by current, sandstone, avoid corrugated steel pipe
Tube wall is sustained damage, destroyed, and ensures the service life of Performance Test of Corrugated Steel Culvert.
Solve above-mentioned technical problem technical scheme be：
A kind of protection against erosion steel plate structure of Performance Test of Corrugated Steel Culvert bottom surface, it includes lining steel plate, self-tapping screw, shaped steel pressure
Plate, connecting bolt, lining steel plate for bending plane steel plate, the bending of the crooked radian of lining steel plate and the body of corrugated steel pipe
Radian matches, and lining steel plate is covered on the bottom surface of corrugated steel pipe, and lining steel plate is by self-tapping screw and corrugated steel pipe bottom surface phase
Connection, section steel pressure plate are placed on the both ends upper surface of lining steel plate, and connecting bolt passes through section steel pressure plate, lining steel plate and steel ripple
Tube wall is fixedly connected.
The protection against erosion steel plate structure of above-mentioned Performance Test of Corrugated Steel Culvert bottom surface, the lining steel plate is wide shared by corrugated steel pipe bottom
Spend for the 1/3-1/2 of corrugated steel pipe circumferential length, the thickness of lining steel plate is 2-5mm.
The protection against erosion steel plate structure of above-mentioned Performance Test of Corrugated Steel Culvert bottom surface, what the corrugated steel pipe bottom surface was covered by lining steel plate
Anti-corrosion material is filled with ripple inner chamber.
The beneficial effects of the utility model are：
After the utility model is laid on Performance Test of Corrugated Steel Culvert bottom, lining steel plate can make the ttom of pipe of corrugated steel pipe be changed into light
Sliding surface, current, sandstone can smoothly be flowed through in drainage procedure, and Steel Corrugated Pipes for Making tube wall will not be caused to wash away in itself, it is therefore prevented that
The anticorrosive coat of corrugated steel pipe is destroyed, and adds Performance Test of Corrugated Steel Culvert whole service life；Tapping screw, section steel pressure plate and connection
Bolt can make lining steel plate be connected firmly with corrugated steel pipe；Anti-corrosion filler in corrugated steel pipe ripple can prevent steel ripple
Plate face between pipe and lining steel plate is corroded by water, increases the service life.The utility model is simple in construction, laying is convenient,
Performance Test of Corrugated Steel Culvert bottom can be effectively protected, prevents corrugated steel pipe tube wall from sustaining damage, destroying, ensures Performance Test of Corrugated Steel Culvert
Service life.
