Background

With the continuous development of urban construction, the urban construction uses less and less land. To build more building space in a limited area, more and more multi-story basements, high-rise and super high-rise buildings are emerging. The construction of urban building groups (such as long triangular areas and bead triangular areas) in the urban edge areas which are considered to be unsuitable as construction sites in the early days brings many new technical problems for the construction technology, for example, the experience data on the successful application of the pile forming of the overlong and large-diameter punched cast-in-place piles is relatively rare, and particularly, the continuous exploration and improvement stage is still kept in the technical field of large-diameter pile foundation rock-socketing construction.

For the ultra-large and ultra-deep pile foundation engineering, because the rock mass at the bottom of the pile foundation has high strength and the depth of the pile foundation entering a rock stratum is required to be deep, the common hammer head has light weight and low capacity of crushing the rock mass in the shape of the hammer head, and the ultra-large and ultra-deep pile foundation rock-socketing can not be realized.

Working principle embodiment:

firstly, a down-the-hole hammer rock drilling machine is used for drilling, hole leading and breaking the internal structure of hard rock at the bottom of a pile foundation to form a honeycomb-shaped hole, so that a subsequent pile punching machine can continuously break and punch the stone, the rock entering difficulty can be reduced for subsequent punching operation, after the drilling of the drilling machine is finished, a circle which is 200mm larger than the pile diameter is drawn by taking the central point of a lofting positioning pile as the center, a vibration hammer is used for driving a pile casing into a soil layer, the soft soil is considered to be easy to generate hole collapse, the length of the pile casing is preferably more than 10m, and the opening of the pile casing needs to be 200mm higher than the ground; after the pile casing is buried, the pile driver is put in place, the matching condition of the center of the hammer head and the pile position is corrected by adopting a cross method, and the error is ensured to be less than or equal to 20 mm; after the hammer heads are centered, a small-stroke hollow hammer is adopted to impact the soil layer, water is added while flushing, after the slurry in the holes reaches a certain concentration, a water pump is started, the concentrated slurry is ejected and controlled in a positive circulation mode, the slurry is circulated to a water pool after the soil is removed through a slurry filter press, and repeated circulation impact pore-forming is carried out. When the hole depth reaches a harder stratum, the heavy punch is impacted; when the hole depth reaches 60m, the overweight hammer head of the utility model is adopted for impacting; the pile driver is matched with the weighting hammer head of the utility model, and the rock mass is crushed by the tooth with large self weight and layered distribution of the hammer head, thereby greatly improving the rock entering efficiency and the rock embedding depth; and (4) adopting intermittent reverse circulation in a slurry discharging and slag removing mode until the final hole is formed.
