Description
Technical field
The present invention relates to a kind of concrete pumping performance testing device, belong to concrete test research field.
Background technology
At present, with the development of concrete pumping mode, concrete pumping performance study is one, concrete research field
More important subject under discussion, because laboratory place and equipment are limited, laboratory can not simulation concrete convey in the duct, cause
Concrete pumping performance study is very difficult.
The content of the invention
It is an object of the invention to：A kind of concrete pumping system safety testing device and method of testing are provided, to solve existing side
The problem of method is difficult to test concrete pumping performance.
To solve the above problems, intend using such a concrete pumping system safety testing device, including upper end open, bottom envelope
The test barrel closed, support is provided with above test barrel, reference test bar is vertically arranged at the surface of test barrel, and reference test bar can
Separate type is fixed on support.
In foregoing test device, the lower end of the support is fixedly installed on the outer wall of test barrel, positioned at test on support
The surface of cylinder is fixedly installed guide cylinder, and guide cylinder is vertically set, and the side of guide cylinder is provided with screwed hole, regulating bolt
One end screw and be arranged in screwed hole and hold out against to reference test bar；
In foregoing test device, the support includes vertical adjustment bar, lateral adjustments bar and connecting portion, the lower end of vertical adjustment bar
It is fixedly installed on the outer wall of test barrel, one end of lateral adjustments bar is fixedly installed on vertical adjustment bar by connecting portion, and
Connecting portion is position adjustable structure on vertical adjustment bar, and the guide cylinder is fixedly installed on the other end of lateral adjustments bar；
In foregoing test device, the lower end of the reference test bar is sophisticated formula structure.
The method that concrete pumping test is carried out using said apparatus, is specifically included：
Load concrete to be tested in test barrel to specified altitude assignment, adjust the distance between reference test bar and concrete, then,
Reference test bar is set to be separated with support, reference test bar is fallen into concrete, and record reference test bar, which drops to, is absorbed in the time static in concrete,
And the depth that reference test bar is absorbed in concrete, to carry out concrete pumping analysis.
Because the pumpability test of concrete is exactly actually the mobile performance of testing concrete in static duct, its with it is mixed
Coagulate native mobility and frictional force between pipeline be relevant, and this method of testing reflect during reference test bar is fallen it is mixed
The above-mentioned performance of soil is coagulated, so as to for testing the pumping of concrete.
Compared with prior art, the present invention provides a kind of simple and effective testing tool for concrete pumping performance study
And method of testing, originally fall into depth and fall time/speed progress concrete pumpable in concrete using reference test bar
Property test, solve the problems, such as that existing concrete pumping is difficult to test, meanwhile, the test device cost is cheap, make it is simple,
Method of testing is also very easy.
