Description
Technical field
The invention belongs to dam body seepage wall building technology fields in hydraulic engineering, and in particular to dam body seepage wall trolley and
Its walling mechanism and the dam body seepage wall construction method for using the trolley.
Background technique
Existing cut-pff wall is that one kind is built in the ground diaphragm wall for playing antiseepage in loose pervious bed or earth and rockfill dam (weir),
Antiseepage wall construction is reliable, good seepage-proof property, adapts to the advantages that all kinds of formation conditions, easy construction and low cost, China's water conservancy
Water power coating and earth rock cofferdam etc. have the generally preferred cut-pff wall of the Anti-seeping technology of anti-consolidation pressure.In addition, existing trolley is general
Including running gear, running gear generally includes moving trolley and drives the motor that walking rotation is dynamic on moving trolley, at the construction field (site)
Often it is equipped with the track with moving trolley cooperation.
Cut-pff wall is divided into dam foundation impervious wall and dam body seepage wall two parts, and leading wall or more in dam foundation impervious wall, to pour dam body anti-
Wall is seeped, dam body seepage wall is continuous structure, generally requires and pours mode by jumping storehouse and build, utilizes property in concrete 5-10 days
Can it is not yet stable and without solidify before be easy release internal stress characteristic, according to " partition programming, spacer block construction, placement layer by layer,
It is integrally formed " principle construction, pour one section every one section.
But the mode that wall form is poured again is cumbersome, and the duration is longer for traditional first constructing, and leads to adjacent two sections of intervals
Time is longer, is easy to generate crack between adjacent two section concretes wall, and the cracking resistance of dam body seepage wall reduces.
