Abstract
A kind of efficient emergency drainage device, it, which is characterized by it, includes power water injection pipe, water pipe, power water injection pipe is fixed on the water inlet side of water pipe, it is in angle a with water pipe water inlet side, angle a is selected in 0 ° 30 °, the delivery port of water pipe is connected to scupper hose, and the delivery port of scupper hose is less than the water inlet of water pipe.The utility model is simple in construction, is skillfully constructed, and after the water at one is drained, whole facility directly is moved into another point by 12 people and continues to draw water, using manually less, labor intensity is low.
Description
Technical field
The drainage arrangement that the utility model belongs in construction, the heavy construction that is particularly suitable for use in grinding concrete construction are made
The efficient emergency drainage device of grinding concrete construction used when handling operation area large area ponding during industry.
Background technology
The grinding concrete dam technology in China proceeded by comprehensive exploratory development and Construction Practice from 1981, application
Scope expands day by day.Concrete is a kind of binder materials, is configured and formed by a certain percentage by aggregate and water, therefore in rainwater weather
More places carries out concrete construction, in time, fast and effectively excludes construction Cang Mianjishui, is to ensure concrete construction quality
Key request.
The main method that existing grinding coagulation soil excludes Cang Mianjishui in work progress has：1st, artificial drainage method：Worker
Utilize water container draining or the small ditch draining of excavated by manual work.This method needs are a large amount of artificial, and labor intensity is high, efficiency is low
Under.2nd, pumping drainage method：Manually water is gathered at hypsography low-lying, water pump energization is then placed and draws water.When arranging method using pump, water
Pump connect electricity the rainy day onsite application potential safety hazard it is big, water pump is also required to often move, and the influence to working face is big.
The content of the invention
The utility model aims to overcome that the shortcomings that existing grinding concrete construction operation area drainage pattern is present, there is provided
One kind is using manually less, labor intensity is low, can in time, rapidly discharge Cang Mianjishui efficient emergency drainage device.
Technical scheme is a kind of efficient emergency drainage device used by the utility model, and it, which is characterized by it, includes power
Water injection pipe, water pipe, power water injection pipe are fixed on the water inlet side of water pipe, are in angle a with water pipe water inlet side, and angle a is selected
Select in 0 ° -30 °, the delivery port of water pipe is connected to scupper hose, and the delivery port of scupper hose is less than the water inlet of water pipe.
Due to the out-of-flatness of grinding concrete construction operation area, low-lying district ponding is caused, the utility model utilizes siphon original
Reason, increase by one section of power water injection pipe on water pipe, and it is at an acute angle with water pipe water inlet side, it is high when being injected in power water injection pipe
During fast current, the guide design of acute angle flows the delivery port of current direction water pipe, and high-velocity flow breaks through whole drainage channel
Peak, siphonage is formed, and produce suction to the water of import when flowing of the high-velocity flow to outlet, ponding is in a steady stream not
It is disconnected to be noted from the import of water pipe to delivery port.Now power water injection pipe can stop water filling.Obtained through field measurement, the water of onsite application
Pipe diameter is 100mm, and power water injection pipe caliber is 22mm, when live flow rate of water flow 10m/s, can form siphonage, pump drainage
Amount reaches 14 cubic metres per hour, completely can be compared with 2.2kw water pumps.
The utility model is simple in construction, is skillfully constructed, and after the water at one is drained, is directly moved whole facility by 1-2 people
Move another point to continue to draw water, using manually less, labor intensity is low.
Brief description of the drawings
The structural representation of Fig. 1 the utility model embodiments 1
The structural representation of Fig. 2 the utility model embodiments 2
Wherein：The scupper hose of 1 power water injection pipe, 2 water pipe, 21 delivery port, 22 water inlet 3.
Embodiment
The utility model is described in detail with reference to view, cited embodiment can make this professional skill
Art personnel more understand the utility model, but do not limit the utility model in any form
Embodiment 1, as shown in figure 1, a kind of efficient emergency drainage device, it, which is characterized by it, includes power water injection pipe 1, water
Pipe 2, power water injection pipe 1 are fixed on the side of water inlet 22 of water pipe 2, are in angle a with the side of water pipe water inlet 22, and angle a is selected
In 0 ° -30 °, the delivery port 21 of water pipe 2 is connected to scupper hose 3, and the delivery port of scupper hose 3 is less than the water inlet 22 of water pipe 2.
It can be pushed down during use with sand hill, ensure lowest part of the device in ponding.Water pipe a diameter of 100mm, the overall length 0.6m of onsite application,
Power water injection pipe caliber is 22mm, and the distance of center and water pipe water inlet is 0.25m, can when the flow velocity 10m/s of high-velocity flow
Siphonage is formed, pump drainage amount reaches 14 cubic metres per hour, completely can be compared with 2.2kw water pumps.
Embodiment 2, as shown in Fig. 2 power water injection pipe 1 and the angle of the side of water pipe water inlet 22 are 0, can be directly in pipe
The inside of the big water pipe in footpath connects a high speed water tube head by iron wire, and high speed head switch is directly opened during use, its
Required water velocity is greater than embodiment 1.Remaining not described part is same as Example 1.
