New breakthroughs in urban comprehensive pipe gallery construction technology
The permeable paving permeable device is a device for inspecting the permeable coefficient of permeable bricks. It is produced according to GBT 25993-2010 permeable paving slab and permeable pavement panel. The utility model has the advantages of simple structure, low cost, easy operation and low detection cost. It is used in the field of building materials technology, especially the permeability coefficient detector for building materials permeable bricks. It uses non-gas water for recycling and improves the detection accuracy.
GBT25993-C1 permeable pavement permeable device I. Permeable pavement permeable device introduction: Permeable pavement permeable device is a device for testing the permeable coefficient of permeable bricks. It is produced according to GBT 25993-2010 permeable paving slab and permeable pavement panel. Low cost, easy to operate, low cost detection equipment. It is used in the field of building materials technology, especially the permeability coefficient detector for building materials permeable bricks. It uses non-gas water for recycling and improves the detection accuracy. Second, the permeable pavement permeable device structure: permeable brick permeability coefficient measuring instrument, is composed of water storage cylinder, sample connection seals, overflow sink, measuring cylinder and so on. An overflow pipe is installed on a side of the overflow water tank and the water storage cylinder at a certain height, and a sample connection sealing member that is easy to disassemble is installed at the bottom of the water storage cylinder. Easy to disassemble the sample. Third, the specific parameters of the permeable paving permeable device: 1, the inner diameter of the water storage tube: 75mm; 2, the height of the water storage tube: 220mm; 3, the size of the applicable test piece: diameter 75 × product thickness; Fourth, the permeable pavement permeable device instructions : The operation must be carried out in strict accordance with the "JCT 945-2005 permeable bricks" and "GBT 25993-2010 permeable pavers and permeable pavement panels". Apply the sealing material or butter to the metal sleeve in the test piece (note: the upper and lower surfaces of the test piece should not touch the sealing material), and wait for the sealing material to solidify and put it into the vacuum device. After a certain period of time, put it into the overflow. The water tank maintains a certain water level when the water storage tank is filled with airless water until the overflow overflow of the overflow water tank. After being stabilized, the flow of water for five minutes is recorded. V. Inspection instructions for permeable paving permeable device: 1. Factory inspection: Refers to the certificate issued by the manufacturer, including the dimensional deviation, appearance, quality and strength level of the project. 2. Type inspection: It means that all technical indicators of the product are inspected by the manufacturer every time or for a certain period of time. If the manufacturer unconditionally entrusts a qualified unit to carry out inspection. 3. Entry inspection and retest items: dimensional deviation, appearance quality, strength grade, current construction unit entrusted
