Construction method for fishing slurry at bottom of cast-in-place pile hole
The invention relates to the technical field of hole bottom slurry fishing, and discloses a cast-in-place pile hole bottom slurry fishing construction method which comprises the following steps: putting a reinforcement cage and a cast-in-place guide pipe into a cast-in-place pile hole, and carrying out secondary hole cleaning on the cast-in-place pile hole; measuring the sediment thickness at the bottom of the cast-in-place pile hole, and determining that the sediment thickness is within a set thickness range; a fishing device is provided and comprises a barrel, a barrel cavity with an opening in the top is formed in the barrel, a slurry inlet is formed in the middle of a barrel cover of the barrel, a movable shaft penetrates through the slurry inlet, the lower portion of the movable shaft penetrates through the slurry inlet and is provided with a bottom cover plate, and the fishing device is put into the cast-in-place pile hole till the bottom of the barrel abuts against the bottom of the cast-in-place pile hole. Continuously lowering to enable the movable shaft to move downwards relative to the cylinder body, and opening the slurry inlet by the bottom cover plate; after slurry in a cast-in-place pile hole enters the cylinder cavity through the slurry inlet, the slurry is lifted to the bottom cover plate to seal the slurry inlet; and the fishing device is lifted out of the cast-in-place pile hole, the slurry in the barrel is poured out, the slurry is detected, and detection data are obtained.
本发明涉及孔底泥浆捞取的技术领域，公开了灌注桩孔底泥浆捞取施工方法，在灌注桩孔中下入钢筋笼以及灌注导管，并对灌注桩孔进行二次清孔；测量灌注桩孔底部的沉渣厚度，确定沉渣厚度处于设定厚度范围之内；提供捞取器，捞取器包括筒体，筒体中具有顶部开口的筒腔，筒体的筒盖中部设有进浆口，进浆口穿设有活动轴，活动轴的下部穿过进浆口，并设有底盖板，将捞取器下入在灌注桩孔中，直至筒体的底部抵接到灌注桩孔的底部后，继续下放使活动轴相对于筒体朝下移动，底盖板打开进浆口；灌注桩孔中的泥浆通过进浆口进入筒腔中后，上提至底盖板将进浆口封闭；捞取器提出灌注桩孔，将筒体中的泥浆倒出，并对泥浆进行检测，获得检测数据。
