Three-step construction method for TRD cement mixing wall test pile
The invention provides a TRD cement mixing wall test pile three-step construction method which comprises the following steps: step 1, construction preparation, step 2, surveying and setting out, step 3, guide groove excavation, step 4, pre-buried box hoisting and placing, step 5, pile machine in-place, step 6, connection of a cutting box and a host machine, step 7, inclinometer installation, step 8, three-procedure wall forming, step 9, cutting box retreating, and step 9, construction of a TRD cement mixing wall test pile. According to the method, the construction capacity of construction equipment under the stratum condition is verified through a wall forming test, the wall forming quality, the cement stirring uniformity, the strength and the waterproof performance are determined, the construction parameters and the construction procedures of the TRD construction method are determined, the excavation wall forming advancing speed and the wall forming effect of the TRD cement stirring wall adopting three procedures (namely first excavation, withdrawing excavation and wall forming stirring) are determined, and the construction efficiency of the TRD cement stirring wall is improved. The guiding perpendicularity of the TRD cement mixing wall cutting box and the perpendicularity of the formed cement mixing wall are determined, a foundation is laid for later construction through overall pile testing, and the later construction quality is improved.
本发明提出一种TRD水泥搅拌墙试桩三步施工方法，包括以下步骤：步骤一，施工准备，步骤二，测量放线，步骤三，开挖导槽，步骤四，吊放预埋箱，步骤五，桩机就位，步骤六，切割箱与主机连接，步骤七，安装测斜仪，步骤八：三工序成墙，步骤九，退出切割箱，本发通过成墙试验验证施工设备在该地层条件下的施工能力，确定成墙质量、水泥搅拌均匀性、强度及隔水性能，确定TRD工法的施工参数和施工工序，确定TRD水泥搅拌墙采用三工序(即先行挖掘、回撤挖掘、成墙搅拌)的挖掘成墙推进速度、成墙功效，确定TRD水泥搅拌墙切割箱导向垂直度、水泥搅拌墙成墙的垂直度，整体试桩为以后的施工打下了基础，提高了后期的施工质量。
