Waste slurry recycling mixing cement-soil press-grouting pile construction process
The invention discloses a waste slurry recycling mixing cement-soil press-grouting pile construction process and belongs to the technical field of mixing piles. The process comprises the following steps: (1) drilling and taking soil; (2) transporting soil and waste slurry; (3) mixing on the ground; and (4) grouting and forming piles. Compared with in-situ mixing, cement and soil can be mixed moreuniformly; the pile formation quality of mixing piles is ensured; the strength is ensured; the usage amount of the cement can be better controlled; the consumption of the cement resource is reduced; the cost is reduced; part of the waste slurry generated by other processes can be treated; the slurry discharging cost can be reduced; the pollution of the waste slurry to the environment is reduced; the current situation that the slurry returning amount is large and the waste of the cement is caused in the construction process of part of in-situ mixing piles in the prior art can be changed, the resource consumption is reduced, and the cost is reduced; a long helical drilling machine is used for drilling downwards to lift grouting; hole forming protection walls do not need to be arranged in pile holes of the mixing piles; the process is simplified; and the cost is reduced.
本发明公开了一种废泥浆再利用搅拌水泥土压灌桩施工工艺，属于搅拌桩技术领域。它包括以下步骤：(1)钻孔取土；(2)土与废泥浆运输；(3)地面搅拌；(4)灌浆成桩。相对于原位搅拌，水泥土搅拌更加均匀，保证搅拌桩成桩质量，保证强度；能够更好地控制水泥用量，减少水泥资源消耗，降低成本；能够处理部分由其他工艺产生的废泥浆，减少排浆成本，降低废泥浆对环境的污染；改变现有的部分原位搅拌桩施工过程中返浆量大，水泥浪费等现状，减少资源消耗，降低成本；利用长螺旋钻孔机向下钻孔、提升灌浆，不需要在搅拌桩桩孔内设置成孔护壁，简化工艺，降低成本。
