Analysis of the problems encountered in the construction process of the gabion mesh factory
In the practical
application of gabion mesh construction often meets some questions. So Hebei
Yishen Wire Mesh Products Co., Ltd will introduce a correction and prevention
measures for grid instability and collapse of the gabion mesh in the
application. It is important to the contact between the questions in the gabion
mesh structure and foundation, especially when the structure is in the flooded,
the water will cause the loss of the soil around the stone cage, this scene is
mainly because the stone space of pipeline flow in these open spaces in the
onset of local acceleration resulting in soil loss, a few cases of stone cage
structure will eventually stabilize, but the most quiet conditions under the
stone cage structure will lose balance, after all the stone cage structure
collapse. Under the circumstances, use the following 2 ways to avoid this
phenomenon occurrence.
(1) Placement of a permeable
cushion between the stone cage and the natural soil layer
(2) Cut down the gabion structure
of water flow and flow velocity.
Between the stone cage and natural soil in
the permeable cloth cushion, such as fabric, they are very useful for the
majority of gabion material for construction. But if the water in the stone
cage structure is very large, it is necessary to carry out the construction of
the thin local rated maintenance. In fact, in the long run, the flow of water
will damage any cushion, so the maintenance is particularly important. In
general, gabion mesh stone cage structure to maintain the local rated a total
of 4, (1) two mesh gabion structure and filling the contact surface between the
straight - (2) weir at the foot of the cofferdam. (3) On both sides of the side
wall of the spillway gabion mesh gabion structure (stilling pool, 4> River
downstream cofferdam of stilling bucket. In these local to set up the semi permeable or impervious
curtain to reduce or stop water flow, semi permeable anti-seepage curtain
available geotextiles production, and impervious curtain is available through
the processing of the guest stone cage net structure. Its production method and the usual gabion
material is constructed of the same, is only in the process of stone filling in
stone area was filled with concrete. Sometimes, even if we take preventive
measures, will also attack the damage scene, at this time, it is necessary to
fill the new stone or gabion material has been replaced by the new damage to
the stone cage, and the surrounding foundation are modified.
Then talk
about the construction elements:
(1)Gabion mesh backfill choice, should satisfies the quality
requirements of the back should not contain humus; fill in and steel wire mesh
of corrosive chemical and electrochemical components and other impurities; bony
material maximum diameter is less than 15cm, and the total content of bone
material beyond the 5rm size shall not be greater than 15%. The maximum dry
density, optimum water content and other parameters of the soil are obtained by
compaction soil experiment.
(2)All adjacent green reinforced gabion mesh component wall
edges are stranded connection, stranding method are all according to the
interval 10~15cm single ring double loop locking interval to stranding, wall
forms a series of the whole face.
(3)No traffic vehicles, transport machinery, paving machinery
and compaction machinery on the road and work on the surface of the exposed
steel bars are prohibited on the surface of the filler. The packing is
necessary to lay the paving, compaction. Each layer of loose paving thickness
should be 30cm, paving the last degree should be uniform; the surface should be
flat after compaction. Paving should be from the surface to the rear of the
wall to the appropriate sequence. Paving and compaction should not be carried
out in rainy days.
(4)The interval wall in the range of 1m, appropriate uses
artificial ramming or light mechanical compaction, compaction machinery shall
not work in the interval wall in the range of 1m, to avoid damage to the
formation of gabion wall kneading.
(5)Green reinforced gabion mesh wall after construction should
be timely across the wall into the spraying or cuttings and on time according
to the request of landscaping maintenance.
