Description

Impervious experimental shedder of concrete for woodland bank protection

Technical Field

The utility model belongs to the technical field of the impervious test block drawing of patterns equipment of concrete and specifically relates to a forestry bank protection is with impervious experimental shedder of concrete.

Background

Mountain forest trees belong to important components in ecological resources in the nature, trees on two sides of a road are often damaged by rain water in mountain areas with developed forestry resources, an effective protection mode is to carry out engineering protection on concrete on slopes on two sides of the road, and due to the special protection operation, concrete with higher performance needs to be selected for engineering operation, and the concrete takes durability as a primary design index. One of the indexes for measuring the durability of the concrete is the impermeability of the concrete, and an important link in the impermeability test process of the concrete is sealing the concrete test piece. The existing inspection method for the impermeability of concrete in China is executed according to the impermeability test in the literature, but GBJ82-85 has been executed for 20 years and a manuscript of new standards has been introduced. The concrete test piece is prepared by the following specific steps: 1. firstly, manufacturing a cylinder or a round table according to the model of the impermeability instrument, forming 6 blocks in each group, removing a mold after 24 hours of forming, brushing cement paste films at two ends by a steel wire brush, and performing standard curing for 28 days; 2. taking out the test block one day before the test, and airing the surface (if the test block is not aired, the sealing material cannot be adhered); 3. coating a layer of sealing material (generally paraffin, asphalt and too dirty) on the side surface of the test block; 4. pressing the test block into a die sleeve (preferably a press machine) preheated by an oven (30-40 ℃), cooling, releasing pressure, and mounting on an impermeability instrument for testing; 5. the test water pressure starts from 0.1Mpa, the water pressure is increased by 0.1Mpa every 8 hours later, and the water seepage condition of the end face of the test piece needs to be observed at any time; 6. when 3 test pieces in the 6 test pieces have water seepage, the test can be stopped, and the water pressure at that time is recorded. 7. The impervious grade of concrete is calculated by the maximum water pressure when 4 test pieces in each group of 6 test pieces are not seeped, and the calculation formula is as follows: s = 10H-1 formula wherein: s-concrete impermeability grade, water pressure (Mpa) when 3 test blocks among H-6 test blocks are subjected to water seepage. In the above steps, sometimes the test piece needs to be broken, and before the test piece is broken, the formwork of the outer surface layer of the test piece needs to be removed.
