Vertical pile underpinning and pile hole sealing method of thick plate basic structure of building

Abstract

The invention relates to a vertical pile underpinning and pile hole sealing method of a thick plate basic structure of a building, comprising the following steps of: (1) drilling a vertical pile hole on the thick plate base by using a machine tool and installing a pile below the vertical pile hole; (2) respectively clearing gaps under the thick plate base and on both sides of the pile top; (3) downwards placing a pile top transverse anti-punching steel bar net in the vertical pile hole, respectively placing both ends of the pile top transverse anti-punching steel bar net in the gaps cleared on both sides of the pile top in advance; and (4) sealing pile heads. The steps (3) further comprises the steps of: firstly, holding the knob of a steel bar to place the pile top transverse anti-punching steel bar net into the vertical pile hole, wherein one end of the net droops, and the other end tilts; then, placing the drooped end of the net into the gap of one side; dragging the knob of the steel bar, placing the other end of the net in the gap of the other gas, and horizontally arranging the net on a steel base plate prefabricated on the pile top. By adopting the invention, the hard work of manual inclined cone hole drilling can be relieved.

Description

technical field [0001] The invention relates to a hole sealing and filling method used when drilling vertical pile holes (press-in piles or pile holes) on thick slab foundations (box foundations, raft base slabs) of buildings. The thick slab foundation works together as a whole, and there will be no serious consequences such as punching damage, invalid hole sealing, and pile foundation floating, so as to avoid the heavy physical work of traditional manual drilling of cone-shaped pile holes. Background technique [0002] At present, in construction projects, due to various complex factors, excessive sinking or even tilting of buildings (structures) is often caused, resulting in cracks and damages of buildings (structures), and in severe cases, the entire building (structure) may be demolished and rebuilt. , causing huge economic losses. In addition, there are some buildings that need to strengthen the foundation due to the addition of floors and renovations. [0003] In ord...
