Abstract

本发明公开了一种用于建筑领域基坑支护的联体砂浆桩墙的施工方法，该方法沿着联体桩墙中心线，用高频液压振动锤桩机在第一个桩位把钢套管沉到设计标高，取出钢套管内的土，成孔合格后，用钢套管内取出的砂土配以水、水泥或石灰投入搅拌机搅拌均匀，拌好的砂浆倒入钢套管内，高频振动拨出钢套管，形成第一根砂浆桩，再在与第一个桩位相咬合的第二个桩位上沉管至设计位置，重复成桩施工步骤，形成联体砂浆桩墙。该施工方法能适用于除岩层外任何地质情况的防渗止水和挡土桩墙的施工，在桩机拨钢套管时高频振动形成密实的砂浆体桩，采取就地取材不仅减少弃土和进场施工材料的运费，还可在确保防渗止水效果前提下降低工程造价。

Description

联体砂浆桩墙的施工方法
一、技术领域
本发明涉及工业与民用建筑领域中的基坑支护施工方法。
二、背景技术
随着土地价格的快速上涨，地下空间的利用受到人们的充分重视，为满足不同深度、不同地质基坑支护的需要，基坑支护技术也向多元化发展。目前，常见的基坑支护止水方法有搅拌水泥土桩法、旋喷注浆法和素混凝土(钢筋混凝土)桩止水帷幕，其中素混凝土桩或钢筋混凝土桩按施工方法有人工挖孔、冲(钻)成孔、搓管成孔、联体筒桩法等几种形式。
以上基坑支护止水方法从适用范围看，水泥土搅拌桩法、旋喷注浆法、联体筒桩法仅仅适用于砂土或软土地质，应用范围受到限制；其中水泥土搅拌桩法、旋喷注浆法还由于桩径较小，且垂直度难以控制，造成桩体上、下部咬合不均匀，常出现下部咬合差甚至相邻两桩未咬合搭接情况，影响防渗效果；素混凝土(钢筋混凝土)桩咬合法中的人工挖孔法因安全没有保证，国家限制使用；冲(钻)成孔法易出现缩颈、夹泥等桩身缺陷，止水效果不理想；搓管成孔法采用全套管方式，成桩质量有保证，但它仅适用于砂性土，其它土质，侧摩阻力大，搓管效率低；联体筒桩虽是目前一种较先进的基坑支护方法，但它需大型昂贵的施工设备，且当软土中夹有硬土层时没法施工。
以上几种基坑支护止水方法可根据需要单独使用或组合使用，但总体上均不能用于硬质土层，使用范围受局限，且普遍都需消耗较多水泥，成本较高，还因凝结时间早，早期强度高，当出现机械故障、停水、停电等情况后，无法按计划咬合成桩施工，往往需另外补桩，增加施工成本。
三、发明内容
本发明的目的是提供一种能适用于除岩石层外任何地质情况、节省施工用水泥、且无过早凝固问题而不需另外补桩、施工成本低、防渗止水效果好的联体砂浆桩墙的施工方法。
为实现以上目的，本发明联体砂浆桩墙的施工方法采用的技术方案是：沿着联体桩墙中心线，用高频液压振动锤桩机在第一个桩位把钢套管沉到设计标高，以机械或人工方式取出钢套管内的土，成孔验收合格后，用套管内取出的砂土与水和胶结材料按施工配合比用量放入搅拌机搅拌均匀，然后把砂浆倒入钢套管内，振动拔出钢套管，形成第一根砂浆桩，再把高频液压振动锤桩机的钢套管在下一个桩位上沉到设计位置，前后桩位相互咬合，重复成桩施工操作步骤，即形成联体砂浆桩墙。
所述胶结材料可根据具体情况采用水泥或石灰。
本公司已获授权的发明专利全套管大直径振动取土灌注桩的施工方法(专利号ZL200610070306.X)具有成桩质量好、环保、效率高等优点，但这种方法施工的是单桩，在基坑支护中不具备防渗止水和挡土的功能，本发明联体砂浆桩墙的施工方法属于该专利技术基础上的进一步技术开发，使单桩联成整体桩墙，不仅实现了防渗止水和挡土的功能，而且能适用于除岩石层外任何地质情况的防渗止水和挡土桩墙的施工，彻底改变了现有防渗止水和挡土桩墙施工方法适用范围窄的缺陷。
本发明联体砂浆桩墙的施工方法采用就地取材，用套管里就地取出的砂或土作为填充料，用很少的水泥或石灰作为胶结材料搅拌成混合砂浆代替较贵的钢筋混凝土材料，在桩机拨钢套管时的高频振动下，形成密实的砂浆体，不仅减少弃土和进场施工材料的运费，还可在确保防渗止水效果前提下降低了工程造价。此外，在无需掺缓凝剂情况下砂浆的凝固时间较长，早期强度低，用高频振动桩机结合全套管，对土体的切割能力强，即使遇到停水、停电、桩机故障等特殊情况停工，重新开工仍可顺利地通过切割前一砂浆桩达到与后一砂浆桩咬合，不需桩外补桩。
四、附图说明
图1是本发明联体砂浆桩墙的施工方法的施工示意图。
五、具体实施方式
下面结合附图和具体实施例对本发明联体砂浆桩墙的施工方法作进一步详细说明。
图1所示安装在振动取土灌注桩桩机振动锤头1上的钢管夹持器2夹住钢套管3在第一个桩位上沉到设计标高，人工或机械方式取土，终孔验收合格后，即可把砂土、水和水泥按施工配合比用量放入搅拌机搅拌均匀形成混合砂浆，然后把砂浆倒入钢套管3内，振动拔出钢套管3，形成第一根砂浆桩4，接着移动桩机到第二个桩位上，第二个桩位与第一个桩位咬合，将钢套管3沉到设计位置，重复成桩施工步骤，循序进行，即形成联体砂浆桩墙。
根据具体地质情况也可采用石灰替代水泥，其他操作步骤不变。
通过桩机拨出钢套管时的高频振动，达到砂浆自身的密实并使桩体咬合界面处的材料相互渗透，提高了联体砂浆桩墙防渗效果。
