A poor foundation reinforcement system and a reinforcement method based on underground concealed arch structures are provided. The system and the method belong to the technical field of poor foundation treatment. The reinforcement system includes multiple columns of pile foundations arranged along a bridge direction. Multiple arch sheets are set in parallel between each two adjacent columns of pile foundations. Each arch sheet includes multiple high-pressure rotary jet piles arranged along the bridge. Each two adjacent arch sheets of the multiple arch sheets are connected by a micro-bending slab disposed on the two adjacent arch sheets, the multiple arch sheets are connected by the micro-bending slabs to together form an arch ring, and a construction joint is disposed between each two adjacent micro-bending slabs of the micro-bending slabs.

A foundation structure is made up of a screw that is vertically adjustable into a pile to a desired height, a ball joint connected to the screw, and load bearing components that can be adjusted on the ball joint in 3-dimensional space with respect to the position of the pile. The load bearing components include one or more plates that define one or more hollow slots into which one or more bolts can be held in place vertically while still having allowance for lateral motion. A load bearing plate at the top of the structure can be laterally translated based on movement of the bolt. The load bearing plate is removably coupled to the floor of a building. The structure allows for vertical, lateral, and angular adjustment, providing tolerance for foundation misalignments due to inconsistencies inherent to topography and/or offset between an intended and an actual point of installation.

A vertical escape structure comprises an escape housing disposed in a vertical orientation and mounted to a ground to maintain structural integrity in the vertical orientation against external flooding. The escape housing includes an interior which is sealed against water entry from exterior flooding and at least one of a staircase, a ladder, an elevator, or a lift disposed in the interior of the escape housing. The vertical escape structure further comprises a connecting walkway to connect the escape housing to a building. The escape housing has a smaller horizontal footprint than the building. The walkway is severable from the building by force without damaging the escape housing to cause water entry from the exterior flooding.

A pile system for support structures includes at least two piles each having a first end, a second end, and a cylindrical elongate body. Each cylindrical elongate body has an inner surface and an outer surface, extends from the first end toward the second end, and defines an internal cavity with a longitudinal axis. Each pile further includes a transition region between the elongate body and the second end, the transition region including an annular seating shoulder disposed on the inner surface of the cylindrical elongate body that defines a step increase from a primary inner diameter to a secondary inner diameter. The first end of a first pile of the at least two piles is configured to be inserted into the second end of a second pile until a first distal edge thereof contacts the seating shoulder of the second pile.
