The invention relates to the technical field of hole-forming construction by drilling anti-pulling piles, and discloses a method for cleaning and brushing the hole wall of the anti-pulling pile into the rock section. Design the elevation of the bottom of the pile, and use a slag fishing bucket to clear the slag at the bottom of the hole; S30, lower the wall brushing bit to the bottom of the hole, and the wall brushing bit has a wall brushing device at the bottom, and the wall brushing device has a plurality of through holes. The brush handle opened and retracted by rotating in the opposite direction, the end of the brush handle has bristles; S40, rotating in the positive direction to open a plurality of the brush handles; S50, rotating the brush wall drill bit in the positive direction again, Clean and brush the mud skin on the hole wall of the rock formation section until it reaches the elevation position of the rock formation section; S60, rotate and shrink a plurality of the brush handles in the opposite direction, and take out the brush wall drill bit. The method for cleaning the hole wall of the anti-pulling pile into the rock section provided by the technical solution of the present invention has a better effect on the wall brushing of the rock formation section.
Description
technical field [0001] The patent of the present invention relates to the technical field of drilling construction of anti-uplift piles, in particular, it relates to a method for cleaning the hole wall of the rock-entry section of anti-uplift piles. Background technique [0002] When the load of the upper structure of the building cannot balance the buoyancy of the groundwater, the whole or part of the structure will be affected by the upward buoyancy, such as the basement structure of the building, the large underground pool, the underground biochemical pool of the sewage treatment plant, etc., in order to ensure that the construction (structure) To ensure the safe use of buildings, uplift piles must be installed. The uplift pile relies on the friction between the pile body and the soil layer or rock layer to resist the vertical pullout force. When the pile end is embedded in the rock layer, the friction force is mainly provided by the rock layer section. [0003] At prese...
