Rolling rock-fill dam construction technology
The invention relates to a rolling rock-fill dam construction technology. The rolling rock-fill dam construction technology comprises the following construction steps that stones are transported intoa site and then discharged; a plurality of parallel lines are marked on the flattened stone; the stone is pre-ground; before grinding, a scraping plate is arranged in front of a grinding roller of a vibration grinder, a through groove is formed in the side, close to the vibration grinder, of the scraping plate, then in the grinding process, the scraping plate shovels the high portion of a rock-fill body, the through groove is aligned with the low portion when meeting the low portion, stone shoveled to the scraping plate falls out of the through groove, and grinding is repeated for 3-5 times until the scraping plate does not have the state of shoveling a large amount of stone any more; and the rock-fill body is formed after grinding is finished, and the rock-fill body is enabled to automatically settle for 5-7 days. The rolling rock-fill dam construction technology has the effects that the surface height of the rock-fill body can be conveniently controlled in the stone rolling process,and the construction efficiency is improved.
本申请涉及一种碾压堆石坝施工工艺，其施工步骤如下：将石料运输至场地中后卸料；在摊平的石料上划出多条平行的线；预碾压石料；在碾压之前，在振动碾的碾压辊前方设置刮板，并在刮板靠近振动碾的一侧开设通槽，然后碾压的过程中，刮板将堆石体较高的部分铲除，遇到高度较低的部分，将通槽对准此处，使铲到刮板上的石料从通槽落出，重复碾压3‑5次，直至刮板不再出现铲出大量石料的状态；碾压完成后形成堆石体，并使堆石体自行沉降5‑7天。本申请具有便于在碾压石料的过程中控制堆石体的表面高度、加快施工效率的效果。
