5 Breguet uses a bulldozer to open, and Yeouido excavates fish ponds or large-scale small pits for building foundation pits in low-lying areas. Bulldozers have the advantages of strong adaptability and high operating efficiency. In the operation of excavation of fish ponds, the use of bulldozers has the following characteristics and requires early excavation. It is advisable to adopt a push-pull machine with two or one pushers and push the bulldozers in parallel or in a push-pull method. The ponds and ponds are usually rectangular. When the excavation is carried out, the soil should be evenly distributed from the middle to the edge of the pond. The average surface area of ​​the pond should be kept low to prevent the water in the soil from infiltrating into the low-lying areas. The soil can be transported on all sides with the shortest distance to improve the area. Operating efficiency. When the excavation to a predetermined depth of 23, or found that the water layer of the earth increased significantly, should concentrate on pushing the side of the head easy to drain outwards, in a short time to push the site to the excavation scheduled Depth or slightly deeper, and trim the pond bottom and slope. Here, the water absorbed by the reservoir is absorbed, and the drainage device is installed here. Trim the bottom of the pond. The bottom of the pond requires that the raft be flattened or slightly inclined toward the drain to prevent the bottom of the pond from bulging or uneven, otherwise it is easy to slip the fish when fishing. As soon as Chengtang is completed, the water at the bottom of the pond is rapidly seepage. Therefore, it should be done quickly. The shutdown should be prohibited in the soft and sandy area where water is contained, so as to avoid silting. = The trimming of the pond is usually done with gears and avoids turning. Note: For example, the soil of the pond embankment must be padded with a compacted layer. One blade cannot be stacked high and then compacted. Otherwise, the voids between the dead bodies of the dead body are difficult to compact and tight, causing leakage of water and dikes in the future. The formation of the slope should be naturally formed during the excavation process, usually the slope is not more than 25. It is forbidden to send the soil on the steep slope, stop the operation on the cross slope 1, and forbid to brake or read on the slope rapidly. When the slope of the embankment is slippery and the soil in the bottom of the pond reaches 4 pm, the dry soil on the embankment can be pushed back in order to increase the friction coefficient of the slope. When working with an excavator, the soil or slime can be pushed onto the slope by the excavator. Once there is a trap, in the absence of rescue tools and rescue machinery, 7 do not throttle heavily to try to save themselves. It is best to use wetland bulldozers to excavate fish ponds.
