Slurry retaining wall construction method
The invention provides a slurry retaining wall construction method. The slurry retaining wall construction method comprises the following steps that firstly, a pile casing is embedded in the pile position of a constructed rotary excavating pile; a drill bit of a drilling machine is placed in the pile casing, and the drill bit corresponds to the pile position center point; according to the pre-calculated initial dosage of the chemical slurry powder, the solution is injected into the pile casing, the initial dosage of the chemical slurry powder is added, and wall protection slurry is formed after rotating and stirring are conducted through the drill bit, the drill bit is adopted to drill downwards to the designed hole depth to obtain a drill hole, in the process that the drill bit drills downwards and reaches the preset designed depth, the average amount of the chemical slurry powder is added into the wall protection slurry according to the average amount, obtained through pre-calculation, of the chemical slurry powder every time the drill bit descends by 1 meter, the preset designed depth is smaller than the designed hole depth, after the preset standing time, the drill bit is adopted for fishing sediment at the bottom of the hole, and the wall protection slurry in the drill hole is left to stand after sediment removal is completed. According to the slurry retaining wall construction method, the construction efficiency is high, the cost is low, and a mud pit does not need to be built.
本发明提供了一种泥浆护壁施工方法，包括以下步骤：先对所施工旋挖桩的桩位上埋设护筒；将钻机的钻头放置在护筒内，使钻头与桩位中心点相互对应；根据预先计算得出的化学泥浆粉的初始用量，往护筒内注入溶液和加入初始用量的化学泥浆粉，并通过钻头旋转搅拌后形成护壁泥浆；采用钻头向下钻进至设计孔深后获得钻孔，其中，在钻头向下钻进并到达预设设计深度的过程中，钻头每下降1米，根据预先计算得出的化学泥浆粉的平均用量，往护壁泥浆内加入平均用量的化学泥浆粉，预设设计深度小于设计孔深；在预设静置时间后，采用钻头打捞孔底沉渣，清渣完成后静置钻孔内的护壁泥浆。本发明施工效率高，成本低，无需建造泥浆池。
