Intentionally want information, please contact Ms. Yang :0318-5,229,383 / 15,343,186,906 QQ: 1,786,282,084 Corrugated metal pipe culvert fill material requirements and filling process a filling material requirements Corrugated Pipe Culvert, arch pipe and arched corrugated structure after the completion of the assembly laying, backfilling, does not require special filling material, generally soil can be. Gravel soil, sandy soil is the ideal backfill material. Difficult to find this type of soil can also use crushed stone or gravel, pebbles and fine-grained mixture. When the fine grained soil composed of cohesive soil or silt stone size, the incorporation should be more than 2/3 of total volume. Within 30 cm from the corrugated tube mouth filling, may not have a big edge size over eight centimeters stones or concrete blocks, frozen, high plasticity clay blocks or other harmful substances. In permafrost areas, culvert less than 2 meters containing soil is not more than 5% gravel filling. b. filling process Tube top fill, should maintain the principle of symmetry and balanced on both sides of the tube. Filling mode, must be layered paving, compaction layer, each layer compacted thickness of not more than 15cm to 25cm the degree of compaction of the fill required to achieve more than 95% of the heavy compaction standards, but there subgrade compaction the same degree. Not yet built the middle of the entrance side walls of masonry arch structure, filling the starting point should be selected in the culvert length direction, and then again at both ends of propulsion; if built at both ends of the end walls of masonry, filling from the beginning advancing to the other side. In the filling process, especially the large arched structure, be observed and the deformation of the corrugated shell exceeds the allowable value, in order to change the filling way. The corrugated pipe culvert adjacent filling vertical minimum fill thickness of the pipe top, both sides, including the filling of the height range of 3/4 times the diameter of the tube side, special attention should be ram (pressure) real. Tube side filling due to a small area, you can not use the roller, you can use the small vibratory compactor compacted. The top of the pipe filling in accordance with the subgrade compaction using the same roller with. Note: minimum fill thickness of the corrugated metal culvert pipe top does not reach the minimum, they should ban all motor vehicle traffic. When the tube top fill foot minimum, but still allow the vibratory roller or heavy hammer on the job, in order to avoid damage to the corrugated metal culvert pipe and the surrounding fill. |
