Background technology
Pervious concrete is the concrete with continuous pore texture, and it has higher water permeability than traditional normal concrete, and aspect obtains pilot application on the walkway of town road, community road, gardens, garden, public square etc. in recent years.Pervious concrete is because of its good rain penetration performance, when raining, road rain water can penetrate into concrete faster, and then supplement the underground water under road, be conducive to get rid of excess surface water, facilitate pedestrian and vehicle pass-through, belong to green building save land with outdoor environment in one of the preferred project of road engineering.The effect of pervious concrete and its water permeability are closely related, but there is at present the technical bottleneck problem of application in practice about the test of the permeable amount of pervious concrete and coefficient of permeability, relevant pervious concrete, particularly adopt standard cube body test specimen to test the permeable amount of pervious concrete and the mensuration of coefficient of permeability, be seen in the little of practice and technology application, in engineering, need in a hurry supporting standard cube body test specimen coefficient of permeability testing apparatus.
Summary of the invention
The utility model provides a kind of pervious concrete standard cube body test specimen coefficient of permeability proving installation, for permeable amount and the coefficient of permeability test of pervious concrete and undisguised pervious concrete, be specially adapted to adopt in the road of residential quarters the water permeability test of pervious concrete.
The technical solution of the utility model is: a kind of pervious concrete standard cube body test specimen coefficient of permeability proving installation, it comprise for hold water and can by bottom surface downwards permeable fixing water level case, be positioned at below fixing water level case for place tested standard cube body test specimen water permeable device, be positioned at the bracing or strutting arrangement and the permeable measurement electricity testing device that support water permeable device below water permeable device; Between described fixing water level case and water permeable device, link together by packoff; Described bracing or strutting arrangement comprises firm banking and is sitting in the permeable support on firm banking, there is proboscis apopore at the foot of permeable support, described permeable measurement electricity testing device is placed on below proboscis apopore, and permeable amount enters in permeable measurement electricity testing device by proboscis apopore.Described water permeable device is shelved in permeable support.
Specific implementation method: standard cube body test specimen making → mounting seat → permeable bearing → permeable test specimen is installed install and seal → add water → test water discharge and water discharge time → calculating coefficient of permeability.
Coefficient of permeability K adopts following formula to calculate:
In above-mentioned formula, K-coefficient of permeability ml/ (m
2s);
The water volume (ml) of infiltration in V-T time;
The height (m) of L-permeable test specimen;
The time (s) that T-water sees through;
A-constant water level height (m);
Area of section (the m of H-permeable test specimen
2).
The beneficial effects of the utility model are, this system architecture compactness, and volume is little, simple to operate, and water consumption is little, and it is efficient, convenient and reliable to test.
