Embodiment Construction
[0029] In this embodiment, the basement support is provided with two slopes. The first slope and the second slope are laid with concrete slabs 2 on the top. The thickness of the concrete slab 2 is 12mm. The grading height is 1.8m, and the water-stop curtain 1 is installed at the outer end of the first grading. The water-stop curtain 1 adopts double rows of deep mixing piles. The amount is 15%. The channel steel retaining weir 4 is set at the slope angle of the first slope, and the channel steel retaining weir 4 is completely buried in the soil at the slope angle. The thickness of the channel steel retaining weir 4 is 12mm, and the height of the channel steel retaining weir 4 is the height of the first slope. 1.25 times of 1.25 times that of channel steel retaining weir 4, a concrete cylinder 3 is set on the outside of the channel steel retaining weir 4, and the inner diameter of the concrete cylinder 3 is 450mm. A steel wire mesh is set at the bottom of the pipe 6, and the ge...

The invention discloses a basement supporting structure in a soft soil area. The basement supporting structure is characterized by being provided with two side slopes; concrete slabs are laid at the top of the first side slope and the top of the second side slope, a water stop curtain is arranged at the end of the outer side of the first side slope, a U-steel weir is arranged at the corner of the first side slope, a concrete tube is arranged on the outer side of the U-steel weir, a drainage pipe is arranged in the middle of the concrete tube, the gap between the drainage pipe and the concrete tube is filled with pebbles, a negative pressure well is arranged in the middle of the horizontal segment of the second side slope, a coping beam is arranged at the top of a slope protection pile, a first anchor rod is fixed to the coping beam through an anchor device, an embedded steel plate is buried in the coping beam, an upper inclined strut is welded to the embedded steel plate and fixed to angle steel after being tensioned by a jack, the angle steel is welded to a steel plate embedded in a concrete buttress, a second anchor rod is fixed to an intermediate beam through an anchor device, and a passive soil reinforcement area is arranged on the inner side of the slope protection pile. The basement supporting structure is low in construction cost and short in construction period.
Description
technical field [0001] The invention relates to a support structure, in particular to a basement support structure in soft soil areas. Background technique [0002] With the rapid advancement of urbanization in China, the field of basement engineering has undergone tremendous development. Factors such as the increasing depth and scale of the foundation pit, the complex surrounding environment, and the increasingly tight construction period have brought opportunities for the update of basement support technology, and at the same time brought engineering safety issues. Especially in soft soil areas, special geological conditions make these engineering safety problems more complicated. How to ensure the safety of basement construction and reduce the cost is a subject that engineers and technicians have to face. Contents of the invention [0003] The invention provides a support structure for a basement in a soft soil area, which solves the problems in the prior art. [000...
