摘要:
An earthen formation is reinforced against slippage by embedding welded wire grid work mats within the formation and securing the mats to precast elongate panels disposed at the face of the formation. The mats serve as anchors for the panels, as well as reinforcing means for the formation. Plural connections secure the mats along the length of at least certain of the panels.
摘要:
An earthen formation is retained by welded wire trays embedded in the formation to effect its reinforcement. A concrete face panel is cast in place at the face of the formation and reinforced by upturned ends on the trays.
摘要:
A retaining structure for an earthen formation wherein spaced anchor members in the form of rock anchors or gridwork mats are embedded in the formation and wire retainers are secured between the anchor members. The retainers comprise primary retention rods secured to the anchors and secondary retention members secured to the rods to span the space between adjacent anchor members. In certain embodiments the anchors are provided with extensions to support form panels in spaced relationship to the secondary retention members and a concrete wall is formed in place between said panels and the secondary retention members.

A method for constructing a mechanically stabilized earthen embankment has the steps of first constructing a wall facing element. A plurality of elongate soil reinforcement elements are attached to the wall facing element. A middle portion of each of the elongate soil reinforcement elements has a plurality of semi-extensible bent segments. Fill soil is added to build the earthen embankment over the reinforcement elements. Movement of the fill soil may create sufficient force to straighten some of the plurality of semi-extensible bent segments, allowing the earthen embankment to move to an active condition thereby reducing the stress on the soil reinforcement elements.

A panel connector has a connection body for connecting with a soil reinforcement rod, and an anchor for connecting the connection body to a concrete face panel. The connection body defines a socket shaped to receive and engage the head of the soil reinforcement rod. The socket includes an insertion aperture having an aperture diameter greater than a head diameter of the head of the soil reinforcement rod, a base having an exit aperture with an exit diameter smaller than the head diameter, and a side slot extending from the insertion aperture to the exit aperture.

A mechanically stabilized embankment system has a connection element adapted for engaging a wall facing element. An elongate soil reinforcement element is adapted to be attached to the connection element and positioned in earthen embankment. A plurality of semi-extensible bent segments are integrally formed by and spaced on a middle portion of the elongate soil reinforcement element such that each semi-extensible bent segment extends laterally from an axis of the elongate soil reinforcement element, but can be pulled straight upon the application of excessive force that might otherwise break the elongate soil reinforcement element.
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 soil reinforced retaining wall includes a soil reinforcing mat connected to a face panel. The face panel is vertically disposed with a back facing the earthen formation and is preformed to include an anchor embedded in the face panel and extending from the back in at least one predetermined location. The soil reinforcing mats are horizontally disposed within the earthen formation in general correspondence with the predetermined location. The mats have an end adjacent the face panel folded to form substantially a right angle portion of the mat including a vertical face and a horizontal face. A right angle member having a vertical face and a horizontal face is disposed in contact with the corresponding vertical face and horizontal face of the right angle portion of the mat. The right angle member is then secured to the anchor such that the right angle portion of the mat is rigidly held therebetween.
摘要:
Connectors are provided for securing soil reinforcing elements to the face panels of a retaining wall for an earthen formation. The connectors comprise rigid eyes fixed to the panels and extensions formed on the elements for extension through the eyes. The eyes and extensions are selectively locked together and serve to orient the reinforcing elements in a horizontal disposition within the soil embankment being reinforced.
摘要:
Low-cost and very effective retaining walls are constructed with stacked, generally rectangular, trays of steel wire fabric sheets, each with one end bent up to form a portion of the wall face. In constructing a wall, a first course of trays is set in place and filled, with filtering rocks and/or mats being placed toward the front and against the bent-up face section and fill soil being placed to the rear of the tray. A second course of trays is then placed on top of the first course and the corner of the face bend of the second course is securely fastened to the top of the lower course. Thus, the top of each face is supported and each course is anchored by the next course, thereby resulting in a strong monolithic and permeable wall that will readily conform to irregularities and settling of the foundation surface.
