An in-situ reconstruction and extension structure of an embankment and a construction method thereof are provided. The structure includes a stepped slope excavated on an existing side slope. A gradient of the stepped slope is the same as that of an extension side slope, the stepped slope is individually intersected with top and bottom planes of existing side slope; a toe of existing side slope is taken as a toe of the extension side slope, and gradient of the extension side slope is determined according to positions of the toe and an expanded width. An outer side of stepped slope is filled with a geogrid reinforcement layer in a layered manner, a slope protection structure is arranged on an outer side of the geogrid reinforcement layer to form extension equivalent side slope; a drainage system is arranged at a bottom of the extension side slope.

Provided are a computer program product, system, and method for controlling moveable robot blocks to dynamically form a barrier. A barrier plan is generated indicating a placement of moveable robot blocks at locations in a coordinate system to form a barrier in a geographical area, wherein the coordinates system indicates locations for the moveable robot blocks to form the barrier. Commands are transmitted to the moveable robot blocks deployed in the geographical area where the barrier is to be formed to cause the moveable robot blocks to move to the locations in the coordinate system in the barrier plan to form the barrier.

An edge protection safety bund system (10) for use in connection with a rock bund made of rock fill. The edge protection safety bund system (10) comprises a bund module (12) having a barrier wall (14) and a base plate (16). The bund module (12) is preferably one of a plurality of bund modules (12) arranged side by side to form an extended barrier wall (14). The barrier wall (14) of each module (12) extends substantially perpendicularly upwards from the base plate (16), and a support web (18) extends at an angle from a rear face of the barrier wall (14) to an upper surface of the base plate (16). In use, when rock fill is dumped onto the rear of the bund modules (12), and allowed to flow back to its natural angle of repose behind the barrier walls (14), it creates a rock bund (20) with a front face formed by the extended barrier wall (14).

An earth retention levee system is disclosed which is constructed from spaced apart facing parallel walls of interlocking sheet piles (1, 2) said sheet piles having outside faces (5) and inside faces (4) formed with gridspines (10) along a longitudinal extent thereof, said gridspines (10) being connected to adjacent edges of geogrids (20) which link said parallel walls and stabilise fill (21) disposed therebetween.
摘要:
A reinforced wall system comprising fill material, a plurality of facing baskets, a plurality of reinforcing members at least partially disposed within the fill material, and an impermeable membrane at least partially encapsulating at least a portion of the fill material and one or more of the reinforcing members. Each of the plurality of reinforcing members is associated with a corresponding facing basket. An outer end of each reinforcing member is above a substantially horizontal portion of the corresponding facing basket. The facing baskets and the reinforcing members are positioned in a plurality of layers, with each layer comprising one facing basket and one corresponding reinforcing member. The impermeable membrane is positioned to span two or more layers of the plurality of layers. At one or more layers of the plurality of layers, a portion of the impermeable membrane is positioned around an outer end of the corresponding reinforcing member.

Embodiments of the invention comprise a system for strengthening a sloped structure such as a berm, basin, levee, or embankment. The comprises first and second opposing sides, the second side being adjacent the sloped structure; a bottom side adjoining bottom edges of the first and second sides, thereby forming a cavity within the first, second, and bottom sides; fill material disposed within the cavity; an impermeable membrane encapsulating at least a portion of the fill material; and a plurality of reinforcing members disposed within the fill material.
摘要:
A method for constructing a mechanically stabilized earthen embankment has the steps of constructing a wall facing element, and determining a plane of maximum force and a zone of maximum force in the earthen embankment to be formed. A plurality of elongate soil reinforcement elements are bent to form semi-extensible bent segments, but such that proximal and distal portions remain substantially straight and inextensible. The elongate soil reinforcement elements are positioned such that the semi-extensible region is within the zone of maximum force, and the proximal ends are connected to the wall facing element. Fill soil is added to build the earthen embankment, and the process is repeated until the earthen embankment is formed.
摘要:
A facing element (10) for reinforced soil structures comprising: a first facing sub-element (12) comprising at least one connecting member (16) configured to connect at least one reinforcement member to said first facing sub-element (12), a second facing sub-element (14), a linking device (22), wherein said first (14) and second (16) facing sub-elements are separated by a gap (20) and are linked together by the linking device (22) such that the first and second facing sub-elements have constant relative position.
摘要:
A system and method are provided for increasing the width of an existing roadway. The system incorporates a reverse-oriented retaining wall and soil nail supports. The retaining wall is formed by a first set of soil nails, wire mesh material, and one or more geotextile material layers. An alternate embodiment forms the retaining wall with a plurality of concrete blocks stacked and spaced to form a block wall. The blocks are mounted over the first set of nails and can be filled with mortar. Backfill material fills a gap between the existing sloping surface and the retaining wall. A second set of soil nails can be provided for additional subsurface support. An upper surface of the backfill material can be paved to form the extended roadway width. The cantilevered configuration of the reverse-oriented retaining wall provides a solution for a less costly retaining wall structure. This reverse-oriented retaining wall is also easier to install than traditional vertical retaining walls that may have to be installed at greater vertical and lateral distances from the existing roadway.
