Step 1.
Get rid of the weeds on the original dam! Clearing weeds from the inside out is a better way to combine new soil with old dams and to prevent termites from breeding.
Step 2.
Dig the foundation! Don't think that only building a house will be able to dig a foundation. The general old dam is done long ago. There was no engineering machinery at the time of the countryside, so the soil pressure was not true. At that time, the earth of the embankment was picked up by the shoulder, and the compacted tool was the homemade big stone roller! In addition, cement is not poured into the slope, so it will leak normally.
Before excavating the foundation, we should calculate the proportion of the slope, the height of the dam, the width of the top, and get the bottom width, so that the silt can be removed on the spot. The silt is placed on the foundation to be filled first. Next I will explain how to deal with the sludge.
Step 3.
Buried culvert pipe! Take the old dike all two half, dig the width according to the size of the excavator, at least let the excavator rotate 180 degrees inside and do not wipe the butt, so that the next excavated soil can be dumped out!
Step 4.
Stop the leak! Dig a groove about 3 meters wide, but also to dig until the field, and then the digger throw dry soil above, the loader is in the lower layer of rolling!
Step 5.
Fill it up! Clean up the loading area first and then load the car. The soil is also exquisite, take the internal supplement! That is to say, if you install a cubic soil, the storage capacity of the reservoir will be increased by one cubic meter.
Step 6.
Brush the slope! The most interesting part of the big guy is the test of machine skills. This I will explain the key to everyone!
First calculate the proportion of good slope, and calculate the lime line according to 1 to 1.8 meters.
The excavator must follow the lime line straight, the cab and the track must be 90 degrees, take a shovel and walk, the excavated soil is not placed in the position of the excavator, because the next step is to take a real slope!
See if a slope is punctual! Want to bevel, long distance to see, in fact, brush slope and leveling the same, their virtual three-point line of natural brush smooth!
After brushing the slope, the next step in accordance with the method of brushing the slope in turn to take a solid picture of the slope, must hold the weight, the slope will be neat!
The way to brush the interior slope is the same!
The growth of the dam is piled up layer by layer. The thickness of the fill layer is about 1 meter. Don't fill it too thick. Otherwise, it will collapse easily if the pressure is not tight. When you add a layer, you must shovel a metre or so on the old dyke. It's like a zipper to pull the newly filled soil and the old dam.
Step 7.
Cover the top! For example, the height required by a dam is 10 meters, then the soil we fill is about 9.5 meters high, and the soil leveling on both sides of the slope is just 10 meters high. The embankment Water Conservancy Bureau requires a 4.5 meter wide cover, so the width of our discharge line will be thrown to 5 meters wide. The height and width of the collected soil after the leveling is natural. Not much difference between!
The loader cooperates with the road repair! It is a success or failure to make some details of the residual mud on the slope.
The reservoir should be slightly modified according to the original topography, making elliptical type as far as possible, and the bottom of the reservoir will be turned into a pot bottom.
