Abstract
A kind of roof drainage system engineering method of testing, actual test is carried out with the roof rainwater drainage ability to Practical Project, is easy to construction engineering test.Comprise the following steps：Closure open valley, measures open valley size, and pipe laying plug on the pipe of family is gone out in siphon drainge system；Horizontally disposed trigonometric scale at roof drain 2m is close in open valley, for measuring liquid level；Siphon drainge system water filling, is persistently added water using live water source to gutter aqua storage tank, until water is full of in the open valley of siphon drainge system, after after stable level, it is ensured that water level is in roof drain top 200mm and highly locates；Static water removal, quickly opens out the pipe stopper on the pipe of family, and starts timing with stopwatch, and liquid level often reduces liquid level and time in 20mm record gutters, observes and record drainage speed and effect, calculates actual drainability.
Description
Technical field
The present invention relates to building roof technical field of drainage, more particularly to a kind of roof drainage system engineering
Method of testing.
Background technology
Displacement is big, standpipe quantity is few, pipe diameter is small because it has for siphon rainwater drainage system
And it is good with building adaptability the advantages of, be widely used in large-sized workshop, terminal, station and wait
The spans such as the Room, gymnasium are big, baroque roofing.But in Practical Project, to roofing siphon
The drainability of formula system only rests on Water drainage system design aspect, to the actual rainwater of siphonic rainwater drainage system
Drainability lacks understanding, and roof drainage system has drainability deficiency, roofing leakage in Engineering Projects
The phenomenon of rain, to the interior space, user brings inconvenience.It is therefore desirable to hydrocone type roofing rain
Water drainage system carries out actual test.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of roof drainage system engineering test side
Method, actual test is carried out with the roof rainwater drainage ability to Practical Project, is easy to construction engineering test.
The technical scheme that present invention solution above-mentioned technical problem is used is as follows：
A kind of roof drainage system engineering method of testing of the invention, comprises the following steps：Closure room
Face gutter, measures open valley size, and pipe laying plug on the pipe of family is gone out in siphon drainge system；
Horizontally disposed trigonometric scale at roof drain roof drain 2m is close in open valley, for measuring liquid
Position height；Siphon drainge system water filling, is persistently added water using live water source to gutter aqua storage tank, until
Water is full of in the open valley of siphon drainge system, after after stable level, it is ensured that water level is in roof drain
Top 200mm highly locates；Static water removal, quickly opens out the pipe stopper on the pipe of family, and use the second
Table starts timing, and liquid level often reduces liquid level and time in 20mm record gutters, observes and remember
Record drainage speed and effect, calculate actual drainability.
Roof drainage system testing is static test, is carried out first against roof drainage system before test
Water filling test, can carry out roof drainage System drainage on the premise of drainage pipeline no seepage and no leakage is ensured
Aptitude tests, specific testing procedure is as follows：
The beneficial effects of the invention are as follows will appreciate that the drainage performance of roof drainage system, measurement are real
The maximum drainability of border roof drainage system, for checking roof drainage system engineering quality, its survey
Design, construction and the acceptance of work of the test result to building roof drainage system are respectively provided with directive function.
Brief description of the drawings
This specification includes such as next width accompanying drawing.
Fig. 1 is a kind of schematic diagram of roof drainage system engineering method of testing of the invention.
Position, component names and corresponding mark are shown in figure：Open valley 1, roof drain 2,
Connecting tube 3, column pipe 4, standpipe 5, go out family pipe 6, pipe stopper 7, trigonometric scale 8.
Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples.
Roof drainage system testing is static test, is carried out first against roof drainage system before test
Water filling test, can carry out roof drainage System drainage on the premise of drainage pipeline no seepage and no leakage is ensured
Aptitude tests, specific testing procedure is as follows：
1. open valley 1 is blocked, the size of open valley 1 is measured, family pipe is gone out in siphon drainge system
Pipe laying plug 7 on 6；
2. horizontally disposed trigonometric scale 8 at roof drain 22m is close in open valley 1, is used
In measurement liquid level；
3. siphon drainge system water filling, is persistently added water using live water source to gutter aqua storage tank, until
Water is full of in the open valley 1 of siphon drainge system, after after stable level, it is ensured that water level is in rainwater
The 2 top 200mm that struggle against highly locate；
4. static water removal, quickly opens out the pipe stopper 7 on family pipe 6, and starts timing with stopwatch,
Liquid level often reduce 20mm record gutter in liquid level and time, observe and record drainage speed and
Effect, calculates actual drainability.
The step 1. in, closure open valley 1 be according to choose measurement roof drainage subregion,
The termination of open valley 1 is blocked with baffle plate high, and is sealed with sealant tape, open valley 1 is formed envelope
The aqua storage tank for closing.Measurement open valley 1 size includes using tape measure gutter long, day furrow width and rain
Bucket is highly.
Roof drainage system engineering method of testing of the invention will appreciate that the draining of roof drainage system
Performance, the maximum drainability for measuring actual roof drainage system, for checking roof drainage system work
Cheng Zhiliang, design, construction and the acceptance of work of its test result to building roof drainage system is respectively provided with
Directive function.
