[Title of the Invention]
Anti-surface erosion block mats, the mat-laying process and the mat-laying equipment
[Claims]
1. Anti-erosion block mat, comprising multiple blocks (1) with their reverse side covered with
flexible sheet (2) that is strong enough to hold up against the weight of the said mats when
lifted by it, and with enough excess on at least 2 sides to hold the blocks down when laid
on the ground with the edges buried. (See Figure 1)
2. Construction plan based on the process of filling a section designed to accept a multiple
number of independent blocks (1) with concrete or mortar while before the latter hardens,
lift the blocks by means of the extra portion at one or both ends of the flexible sheet (2),
and anchor the blocks by means of the flexible sheet (2) ends while leaving a small gap
between the sectioning and the blocks.
3. Anti-erosion block mat laying equipment having a long beam (3) on which a movable block
(4) travels along the long axis and a pinch-pickup (5) attached to the movable block. The
pinch-pickup (5) in turn consists of the structural support (6), which is hinged to the beam
(3), the link lever (7) attached to the upper frame (6a) of the structural support (6) and the
lower frame (6b) attached to the upper portion of the said lever (7) working in consort with
one another and a push-pressure device (8) to pinch-lift the extended portions of the
flexible sheet (2) to lift the block mat. When the push-pressure device (8) exerts the
pressure on the said lower frame (6b), the hinge (9) of the said link lever (7) and the
push-pressure device (8) passes the line drawn vertically from the hinge of the link lever
and the upper frame (6b), the said link lever is locked.
[Excerpt from Detail Description of the Invention and Drawings]
This invention concerns the mechanically laid anti-erosion block mats used on surface of
banks, on levies, railroad and road elevations, the easy process of laying the mats and the
block mat laying equipment. More specifically, the anti-erosion block mats of this invention
include strengthening the adhesion of the block mats to the flexible backup sheet, and enabled
the mechanical laying by means of extensions left to the sides of the block mats. The
block-laying equipment of this invention, furthermore, has built into it a pinch-pickup device
designed for the flexible backup sheet.
