Abstract
The invention discloses a kind of armored concrete prefabricated rectangle pressure pipe; it is the combination by two special flange formula connecting plates and reinforcing mattress board concrete; form rectangular tube; special flange formula connects main steel plate and steel plate for sealing water and protection steel plate, the heat-insulated steel plate of secondary welding, is all full weld; level weld seam requirement is air tight; steel grid and special flange formula connecting plate will also weld, so as to reach, the pipeline of anti-leak and allowable stress.
Description
Technical field
Armored concrete prefabricated rectangle pressure pipe of the present invention, be using be welded to connect connected with flange can, can be with
Install elbow, valve, sluice gate and shockproof joint etc. additional, unrestricted extend extends unrestricted, construction is simple, usage time with multi-direction
Often, good maintenance, anti-leak, but also environmental protection.
Technical background
Water is source for the survival of mankind, but is leaked due to urban sewage sewer and directly arranged in river, causes ground
The serious pollution at lower water source, also rural area are ploughed conveyance canal, typically repair conveyance canal with about ten years just dying, the present invention
Armored concrete prefabricated rectangle pressure pipe, is just solved, and a series of problems such as leakage pollution and usage time are short, can also be held
By certain pressure.
The content of the invention
The present invention mainly employs the knot of two special flange formula connecting plates and armored concrete prefabricated rectangle pressure pipe
Closing, the special flange-type structure in two is the same, is made up of five parts, 1, seal plate, 2, protection board, 3, reinforcement, 4,
Secondary welding protection board, 5, main adpting flange formula plate, armored concrete prefabricated rectangle pressure pipe main body be double steel bar grid and
Individual layer steel grid, determined according to the size of pipe and pressure, then casting concrete can, handle during rectangular pressure pipe construction
The alignment welding of tube head flange form connecting plate, the increasing punching of special flange formula connecting plate periphery can also be tightened up a screw and also may be used
With.
Brief description of the drawings
Fig. 1 is the formula connecting plate front elevation of jus singular half of the present invention.
Fig. 2 is special flange formula connecting plate exploded cross-sectional schematic diagram.2 be steel plate for sealing water in wherein Fig. 2, and 3 be reinforcement,
4 be protection steel plate, and 5 be secondary welding thermal insulation protection steel plate, and 6 be main connecting plate.
Fig. 3 is armored concrete prefabricated rectangle pressure pipe main body figure of the present invention, and 7 in wherein Fig. 3 are steels grid.
Embodiment
As shown in figure 3, two special flange formula connecting plates are placed on two, centre plus steel grid, then transverse slat is installed poured
Upper concrete, flange form connecting plate and seal plate, protection board, secondary welding thermal insulation protection plate want full weld, and level weld seam requirement is not
Gas leakage, steel grid and main connecting plate will also weld, and ensure the bulk strength of pipeline.
Claims (3)
1. special flange formula connecting plate gives invention protection.
2. armored concrete prefabricated rectangle pressure pipe, and the concrete prefabricated pipe such as circle, polygon give invention protection.
3. armored concrete prefabricated rectangle pressure pipe can also make elbow bend, multi-angle bend, and three can or elbow and more
It is all that direction connector belongs to the present invention.
