Description
Technical field
The present invention relates to field of civil engineering more particularly to a kind of rubber concrete pipes.
Background technology
Pipe of concrete is the pipe made of concrete or armored concrete, for conveying the fluids such as water, oil, gas, by pipe
Ability to bear difference, low-voltage tube and pressure pipe can be divided into.The general pipe of concrete coefficient of roughness is high, and water velocity is low, peace
Joint is more, and intolerant to corrosion in water；On the other hand, pipe of concrete needs pre-production to transport the place of installation again,
Because the problems such as road bump can lead to the generation of the situations such as damaged, fracture in transportational process, and due to durability it is not high so that
It is higher to change pipe frequency, the economic loss so as to caused by is also on the increase.
Invention content
The present invention seeks to solve the above problems, a kind of durability degree height of experimental study and rubber concrete not easy to break
Pipe.
To achieve these goals, the technical scheme is that：
A kind of rubber concrete pipe, the rubber concrete pipe are made of rubber concrete, and rubber concrete includes water, water
Contain rubber in mud, fine aggregate, coarse aggregate, wherein fine aggregate, the volume ratio in fine aggregate shared by rubber is 3%.
Further, water in the rubber concrete, cement, fine aggregate, coarse aggregate mass ratio be water：Cement：Thin bone
Material：Coarse aggregate is equal to 185：411：678：1106.
Further, the rubber is rubber grain and/or rubber powder.
Further, the radius of the rubber grain is 0.05mm.
Further, the rubber concrete pipe is divided into low-voltage tube and pressure pipe, and the optimum pressure ratio of low-voltage tube is 0.5,
The optimum pressure ratio of pressure pipe is 1.
Compared with prior art, the invention has the advantages and positive effects that：
The present invention obtains load-deformation curve by using to the research of rubber concrete test specimen, avoids remaking rubber
Economic waste caused by glue pipe of concrete, and the manufacturing process of rubber concrete pipe is complicated compared with test specimen, and influence factor is numerous,
Various influence factors are avoided by ansys simulation calculating, error is caused to experimental data, so as to ensure that the standard of experimental data
True property；On the other hand, rubber concrete pipe can improve the toughness and durability of pipeline, be not easy to run because of road surface in transportational process
The factors such as winnow with a dustpan damage pipeline, avoid and bring economic loss, and rubber concrete pipe has that connector is few, from
The advantages that heavy and light, toughness is high, reduces the difficulty of installation, increases prospect of the application.

Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
Concrete is 0.45 by the ratio of mud, and mass ratio is water：Cement：Fine aggregate：Coarse aggregate=185：411：678：1106,
Fine aggregate, coarse aggregate are the use material of concrete in the prior art, and thin bone is substituted in equal volume using rubber grain and powder
Material manufactures 144 test specimens, and makes two kinds of strength tests (7d, 28d) respectively to two kinds of grain sizes (2mm, 0.2mm), passes through experiment
Load-deformation curve is obtained, as shown in Figure 1, Figure 2, Figure 3 and Figure 4, this is the premise that ansys is calculated to load-deformation curve.
The finite element model of random rubber grain enhancing pipeline is established on ansys platforms, by changing rubber grain
The parameters such as size, volume and pressure ratio (medium pressure and soil pressure ratio), the stress intensity of more each model；Rubber concrete pipe
Model pipeline internal diameter 400mm, thick 100mm, pipe range 1500mm, volume ratio is respectively 0%, 3%, 5%, 8%, 10%, is scaled
The volume substitution rate that rubber grain substitutes fine aggregate is 0%, 0.86%, 1.42%, 2.28%, 2.84%.Soil pressure is 2MPa, is situated between
Matter pressure is 0,0.4,0.6,0.8,1.0,2,3 megapascal, and medium pressure is 0,0.2,0.3,0.4,0.5,1,1.5 with soil pressure ratio.
Experimental data is for example following shown
Table 1 be pipeline pressure than the maximum stress of the rubber concrete pipe stress intensity of different rubber volumes under being 0.3 and
Minimum stress (MPa)
Table 2 be under rubber volume is 5% different pipeline pressures than rubber concrete pipe stress intensity maximum stress and
Minimum stress (MPa)
Table 3 be pipeline pressure than different rubber volumes under being 0.3 rubber concrete pipe von mises stress most
Big value and minimum value (GPa)
Table 4 be under rubber volume is 5% different pipeline pressures than rubber concrete pipe von mises stress
Maximum value and minimum value (GPa)
By comparing the stress intensity in above-mentioned experimental data, so that it is determined that rubber optimal mixing amount is 3%, rubber
Grain optimum radius is 0.05, and pressure ratio is 1, and what it is actually due to transport is the substance that compares low pressure, pressure than often below 1,
Optimum pressure is more best than 0.5 at this time.
