Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
The invention comprises the following materials in percentage by mass:
soap: adopts old soap (the invention is a reunion brand) with the mass of 100 parts
Water: the mass is 40-50 parts (added according to the condition)
Mineral powder: specification type is S95, and the mass is 5 parts
Silica fume: the mass is 1 part
The method for preparing the sealing material by adopting the materials comprises the following steps:
1. cutting soap into small pieces, and placing into a prepared iron barrel.
2. Adding water with the required proportion and mass into an iron bucket, then putting the iron bucket into an oven to be heated until the water is melted, and taking care to stir during the heating process, otherwise, the water is easy to overflow.
3. After melting, adding mineral powder and silica fume in required proportion and mass, stirring uniformly, and cooling to room temperature.
4. After cooling to room temperature, the user feels whether the required state can be achieved by hand, if the required state cannot be achieved, a proper amount of water is added to continue heating until the required state is melted, and then the mixture is cooled to room temperature. The cooled state is solid, but softer. The old soap contains grease, a waterproof effect can be achieved during a test, and the cohesiveness of the old soap can be enhanced after mineral powder and silica fume are added, so that the old soap is easier to recover.
The testing steps are as follows:
1. on the road surface of the test road section, a test position is selected according to a random sampling method, 5 test points are measured on each test road section, and test marks are marked by using the strokes of chalk.
2. Before the test, the surface is cleaned by a broom, and sundries on the surface of the road are brushed away by a brush. The presence of impurities can affect the water infiltration on one hand and the sealing effect of the water permeameter and the road surface or the test piece on the other hand.
(2) The test steps are as follows:
1. the plastic ring is placed at the center of the test piece or at a measuring point on the surface of the road surface, the plastic ring is drawn along the inner side and the outer side of the plastic ring respectively by chalk, and the part between the outer ring and the inner ring is the area needing to be sealed by the sealing material.
2. The annular seal region is subjected to a sealing treatment with a sealing material, taking care not to let the sealing material enter the inner ring. If the sealing material inadvertently enters the inner ring, it must be scraped off with a scraper. Then, the strip-shaped sealing material which is twisted into the thickness of the thumb is stacked in the center of the annular sealing area and is stacked into a circle. The sealing material is twisted into strips and piled into a circle, so that the sealing material can be spread more uniformly without gaps when the water seepage meter is placed in the annular sealing area.
3. The water seepage instrument is placed on a test piece or a measuring point on the surface of the road surface, the center of the water seepage instrument is coincided with the center of the circular ring as much as possible, then the water seepage instrument is pressed on the surface of the strip-shaped sealing material slightly with strength, and then the counter weight is added to prevent pressure water from flowing out from a space between the base and the road surface.
4. And closing the switch, filling water into the vector cylinder, and then opening the switch to discharge the underwater flow in the vector cylinder out of the symptom gas at the bottom of the water seepage instrument, and discharging all the bubbles at the bottom of the water seepage instrument by lightly pressing the water seepage instrument with two hands when the water surface descending speed in the equivalent cylinder is slowed. The switch is closed and the vector letter is filled with water again.
5. When the switch is turned on, the stopwatch is started immediately to start timing when the water level descends to the I00mL scale, and the scales of the meter tubes are read once every 60s till the water level descends to 500 mL. During the test, if water seeps out from the base and the sealing material, the base and the road surface are not sealed well, and the base and the road surface are moved to a nearby dry road surface for operation again. If the water surface descending speed is slow, the water seepage amount of 3min can be measured, and the water surface can be stopped, if the water surface descending speed is fast, the water surface reaches the 500mL scale mark within the time of less than 3min, the time when the water surface reaches the 500mL scale mark is recorded, if the water surface descends to a certain degree, the water surface basically keeps still, and the water is basically impermeable or not permeable at all, and the report indicates that the water is basically impermeable or not permeable at all.
6. And selecting 5 measuring points on the same detection road section according to the steps to measure the water seepage coefficient, and taking the average value of the water seepage coefficients as a detection result.
The novel sealing material main body adopts the raw materials of old soap and water, overcomes the defects of difficult cleaning and high cost in the prior art, and has great popularization value in the field of water seepage test sealing materials.
