Description
Technical field
The present invention relates to Earth Dam Construction technical field, specially a kind of earth dam widens construction technology.
Background technology
Earth dam is the dam built up using local earth material and sand, gravel, ovum gravel, ballast, building stones etc..It is a kind of ancient and arrived
The water retaining structure that the present also continues to develop and is used widely, sometimes referred to as earth and rockfill dam.Some particular condition in use are often needed
Original earth dam is widened, but widen width it is wide in the case of frequently can lead to caving in for earth dam widened section,
Cause the accident generation, and these are the problem of we need to solve.
The content of the invention
Widen construction technology it is an object of the invention to provide a kind of earth dam, the earth dam widens construction technology specific steps such as
Under：
S1：Cleaning to earth dam matrix slope top layer, the impurity on earth dam matrix slope top layer is removed, by the weeds on top layer and filling
Wood is purged, and trees is implanted with, it is necessary to which trees are removed if being planted on earth dam matrix slope, while needing trees ' root by soil
In dig；
S2：The construction of first rammed earth step layer, earth filling tamping is carried out to earth dam matrix slope top layer, and rammed earth layer needs to be fabricated to platform
Scalariform, the width of the horizontal direction of step needs to be maintained at 20-30 centimetres；
S3：First widens the construction of matrix, needs progress first to widen applying for matrix after the construction of the first rammed earth step layer is finished
Work, to mound outside the first rammed earth step layer, while first widens in matrix and need press-in cement concrete stake, base is widened to first
Body is compacted, while a diameter of 7-10 centimetres of the cement concrete stake of press-in, first widens the mound horizontal width of matrix
For 50-100 centimetres；
S4：The construction of second rammed earth step layer, the second rammed earth layer is identical with the first rammed earth step layer form of construction work, is carried out after mound
Tamp to be step-like, the width of step horizontal direction is 20-30 centimetres；
S5：Second widens the construction of matrix, needs to carry out the second construction for widening matrix after constructing to the second rammed earth step layer, the
Two widen in matrix need press-in cement concrete stake, cement concrete stake a diameter of 7-10 centimetres, second widens base layer
When widening matrix for outermost layer, the second width for widening base layer horizontal direction is 40-70 centimetres；
S6：The maintenance on earth dam top layer, second, which widens matrix, widens after the completion of matrix construction as outermost layer, it is necessary to be carried out to slope
Slope protection plate is built, and Slope protection plate needs to plant shrub to the hollow part of Slope protection plate after building, and strengthens bank protection ability.
It is preferred that, the first rammed earth step layer and the second rammed earth step layer use yellow soil and sandstone grain in proportion for
2:The material of 1 mixing.
It is preferred that, described first, which widens matrix and second, widens matrix and is needed in work progress using watering so that soil
Lower floor so that first finally constructed widens matrix and second and widen matrix more consolidation, and irrigation amount is often stood according to 50-70 kilograms
The mode of square rice soil is carried out, while widening the construction at least needing interval to carry out subsequent processing for 2 days after matrix construction.
It is preferred that, described first widen matrix and second widen in matrix cement concrete stake between need to wind Buddhist nun
Imperial mesh sheet, more helping prevents that widening matrix collapses.
It is preferred that, described first widen matrix and second widen be pressed into matrix cement concrete stake length control exist
0.5-4 meters, cement concrete pilespacing must not be less than 30 centimetres from the vertical distance of topsoil.
Compared with prior art, the beneficial effects of the invention are as follows：Rammed earth step layer of the present invention and the side for widening matrix interval
Formula widens earth dam, and the setting of rammed earth step layer can make it that widening matrix is preferably attached on dam body, it is to avoid widen matrix
Landslide, prevents from widening matrix level and widens that width is excessive, cause the generation of landslide, can improve the solidness of earth dam, lead to simultaneously
Cross rammed earth step layer and widen the setting at matrix interval, the degree that earth dam is widened can be improved to the full extent.
