Description

一种双向整体搅拌设备及采用其加固浅层软弱地基的方法 技术领域
本发明涉及浅层软弱地基加固技术，具体涉及一种双向整体搅拌设备及采用其加固浅层软弱地基的方法。
背景技术
近年来，随着我国公路工程的快速发展，各种复杂问题凸显出来，其中，软弱地基问题的存在给公路桥梁建设施工带来了一定的考验。软弱地基包括淤泥、淤泥质土、泥炭、泥炭质土等，这类土的天然含水量高、孔隙比大、压缩性高、抗剪强度低，若处理不当，极易引起路面沉降或下埋管道的断裂等问题。工程中常见的处理方法有换填法，抛石挤淤法，垫层法以及强夯等方法，然而这些方法都存在一些局限性，尤其是在城市道路施工中，环保问题、工期问题以及场地限制等问题，均给传统的处理方法带来了很大挑战。而目前普遍使用的水泥土搅拌桩法，如专利一种双向水泥土搅拌桩(公开号CN205242387U)，其公开了一种具有内钻和外钻反向并进行双向搅拌的水泥土搅拌桩，但是此种装置仍然存在水泥土搅拌不均，成桩质量不佳的问题；此外，在处理工期紧迫的道路建设中的浅层软弱地基时，其深层处理的优势显得“大材小用”，再者，其“桩机定位→搅拌下沉→搅拌提升→成桩→桩机移位”的施工工艺进程较慢，且桩与桩之间会残余少许软土，难以达到对软弱地基整体加固的效果。
发明内容
发明目的：本发明的目的在于解决现有的双向水泥土搅拌机无法应对各种不同环境下软土的搅拌，仍然存在水泥土搅拌不均，成桩质量不佳的问题，以及采用现有的双向水泥土搅拌机进行软土搅拌固化无法灵活移动，施工工艺进程慢，且桩与桩之间会残余少许软土，难以达到对软弱地基整体加固的问题。技术方案：为解决上述问题，本发明采用以下技术方案：

进一步地，所述内钻装置包括内钻芯杆、在内钻芯杆上并沿水平方向设置的内钻刀片和设置于内钻芯杆端部的钻头，所述外钻装置包括外钻套管和连接在外钻套管下方的外钻搅拌器，外钻搅拌器包括构成外钻搅拌器外框架的外刀片和设置于外刀片构成的外钻搅拌器外框架内的内刀片；所述内钻刀片包括设在外钻搅拌器外框架内的上刀片和外钻搅拌器外框架下方的下刀片。
进一步地，所述内刀片、上刀片和下刀片均设至少1排。
进一步地，所述外钻装置和内钻装置的沿水平方向设置的刀片呈等角度交错分布。
进一步地，所述外钻搅拌器外框架包括水平方向设置的水平刀片以及能够与外刀片接合拼接成不同形状的框架刀片。
进一步地，所述机身为挖掘机机身，动力传动系统由挖掘机的动力系统驱动。

1)对双向整体搅拌设备所需施工的场地周边进行清理；
2)采用抽水机将软土地基上部的积水抽净；
3)通过挖掘机机身自身的动力，将挖掘机机身开动至所需施工的场地，并将搅拌装置正对所需施工的场地；

进一步地，所述步骤5)中，双向整体搅拌设备通过机身的移动、 动力传动系统控制外钻装置和内钻装置的升降以及机械手的操控来实现所需施工范围内的灵活移动。
本发明与现有技术相比，具有以下有益效果：
(1)对浅层软弱地基进行整体加固，施工方便、灵活，加固效果明显，避免了残留软土问题；
(2)外钻装置和内钻装置的双向搅拌能够形成一定的加固范围，不同布置形式的刀片保证了加固范围内固化剂与软土的混合均匀性，两者的结合作用确保了固化体的质量，且提高了施工功效；
