Method for cleaning holes of mountainous area inland river ramp wharf cast-in-place piles through cooperation of air compressor and guide pipe
The invention relates to the technical field of pile hole construction, in particular to a mountainous area inland river slope ramp wharf cast-in-place pile hole cleaning method through cooperation of an air compressor and a guide pipe, which comprises the following steps: S1, preliminary hole cleaning: applying pressure to slurry, inputting the slurry into a pile hole, synchronously pumping out and filtering the slurry mixed with muck at the bottom of the pile hole, transferring the muck, and transferring the muck into the pile hole; the filtered slurry is input into the pile hole again; s2, secondary hole cleaning is conducted, specifically, after the reinforcement cage is installed in place, a guide pipe is arranged on the inner side of a slurry pipe, an outlet of the guide pipe extends into the bottom of the pile hole and then is lifted by 20 cm, then slurry is pumped out through the slurry pipe, muck is screened through a slurry separator, and then the slurry flows back into the pile hole from the outer side of the slurry pipe; synchronously inputting air of the air compressor into the bottom of the slurry pipe through a guide pipe and enabling the interior of the slurry pipe to be in a negative pressure state; and S3, the step S2 is repeated till the content of the muck in the mud in the pile hole is reduced to the construction requirement. According to the device and the method, pollution to rivers is reduced, and meanwhile, relatively heavy sediments are relatively fully removed.
本申请涉及桩孔施工技术的领域，涉及一种山区内河斜坡道码头灌注桩利用空压机配合导管清孔的方法，其包括以下步骤：S1、初步清孔：对泥浆施加压力并输入桩孔内，并同步将桩孔底部混有渣土的泥浆抽出过滤后，将渣土转运，过滤后的泥浆重新输入桩孔；S2、二次清孔：在钢筋笼安装到位后，采用导管设置于泥浆管内侧，将导管的出口伸入至桩孔底部后再提升20cm，此后通过泥浆管将泥浆抽出并经过泥浆分离器筛分渣土后自泥浆管的外侧回流至桩孔内，同步通过导管将空压机的空气输入值泥浆管底部并使得泥浆管内部呈负压状态；S3、重复步骤S2，直至桩孔内泥浆中渣土的含量降低至施工要求。本申请减小对河流污染的同时，相对充分的将相对较重的沉渣清除。
