The invention relates to the technical field of uplift pile drilling and pore-forming construction, and discloses a method for cleaning and brushing a hole wall of a rock-entering section of an uplift pile. The method comprises the following steps that S10, rotary drilling and pore-forming are carried out to a designed pile bottom elevation by using a rotary drilling rig, and hole bottom slag removal is carried out by using a slag fishing drilling bucket; S30, a wall brushing drill bit is lowered to the bottom of the hole, a wall brushing device is arranged at the bottom of the wall brushing drill bit, the wall brushing device is provided with a plurality of brush handles which are rotationally opened in the forward direction and rotationally contracted in the reverse direction, and bristles are arranged on the end parts of the brush handles; S40, the multiple brush handles are rotated and opened in the forward direction; S50, the wall brushing drill bit is rotated in the forward direction again, and mud cakes on the hole wall of the rock stratum section are brushed till the mud cakes are brushed to the elevation position of the rock stratum section; and S60, the multiple brush handles are rotated and contracted in the reverse direction, and the wall brushing drill bit is taken out. According to the technical scheme of the method for cleaning and brushing the hole wall of the rock-entering section of the uplift pile, the wall brushing effect on the rock stratum section is better.
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...
