Novel construction technology of cemented sand-gravel dams
The invention belongs to the technical field of construction of cemented sand-gravel dams, in particular to a novel construction technology of cemented sand-gravel dams. Cemented sand-gravel materialsare directly spread on the dam, and then the cemented sand-gravel materials are sprayed. After mixing the cemented sand-gravel materials, the final rolling construction is carried out. Through the cooperation of special machine, a mixing and shotcreting machine and a continuous mixing machine, natural sand-gravel materials can be fully utilized, the maximum particle size limit of the aggregate isappropriately relaxed, and the use of large-scale mechanical mixing is reduced during the construction process. The technology reduces the project cost, and can accurately control the amount of cementitious materials. Due to the further relaxation of the maximum aggregate particle size limit, the waste can be reduced, the construction cost can be reduced, and the construction speed can be improved. The technology shortens the construction period and further reduces the project cost.
本发明属于胶凝砂砾石坝施工技术领域，具体涉及一种胶凝砂砾石坝新型施工工艺，将砂砾石材料直接上坝摊铺，再进行胶凝材料的喷浆，对胶凝砂砾石材料的翻拌，最后进行碾压施工，通过专用设备搅浆喷浆机和连续翻拌机的相互配合，能够充分利用天然砂砾石料，适当的放宽骨料最大粒径限制，在施工过程中降低了大型机械拌合的使用，降低了工程造价，并且能够精准的控制胶凝材料的用量，并且由于进一步的放宽了骨料最大粒径限制，弃料便会减少，降低了施工成本，并且加快了施工速度，使工期缩短，进一步的降低了工程造价。
