Description
Technical field
The present invention relates to cubic metre of earth and stone stemming operation technical fields, high more particularly to native face after a kind of cubic meter of backfill
Degree control measurement method.
Background technique
The cubic metre of earth and stone, is the general name of the earthwork and the cubic meter of stone, is Tu Heshi, and measurement unit is to be generally cubic meter.Common soil
Stonework has: levelling of the land, foundation pit (slot) and pipe canal digging, road excavation, civil air defense constructions and installations excavation, terrace banket, and roadbed is filled out
It builds and foundation pit backfills.Reasonable arrangement construction plan is wanted, tries not to be arranged in rainy season, while applying to reduce earth and rock works
Expenses of labour is used, and is implemented and is not accounted for or account for less farmland and arable land and be conducive to the principle built up fields with changing, to make the reasonable tune of the cubic metre of earth and stone
With scheme, overall arrangement.Earth and rock works are an engineering projects wide, amount is big, labour is heavy, in the construction process,
The condition of construction is also extremely complex.
In cubic metre of earth and stone stemming operation, the foundation pits such as pond, hollow are filled generally by way of back-filling in layers, often
It backfills one layer to need to measure backfill height (i.e. flatness), the native face height of this layer after filling cannot be excessive or crosses and be less than
This layer of absolute altitude, measurement result in error range after, just can be carried out next layer and fill, be all at present random for its elevation carrection
Several points are selected on the native face of this layer, are measured by level meter in each reconnaissance, when the levelness that all the points are measured is certain
It in error range, just carries out next layer and fills, otherwise continue to roll until meet the requirements, the mode of this random measurement not section
It learns, the data measured are inaccurate, and have randomness, measure if being to try to choose more point, operation is again pretty troublesome, surveys
Amount efficiency is low.
Therefore above-mentioned technical problem how is solved, there is very much realistic meaning to those skilled in the art.
Summary of the invention
It is an object of the invention to: in order to solve after every one layer of the backfill of the existing cubic metre of earth and stone, to measure the layer height be by random
The method for selecting several points to measure on the native face of this layer has randomness, the data inaccuracy measured, if be to try to choose compared with
More points measure, and pretty troublesome, the low technical problem of measurement efficiency, the present invention provide soil after a kind of cubic meter of backfill again for operation
Face height controls measurement method.
The present invention specifically uses following technical scheme to achieve the goals above:
Native face height controls measurement method after a kind of cubic meter of backfill, comprising the following steps: one layer of soil is backfilled in foundation pit
After the cubic meter of stone, middle section chooses a central point N on the native face of this layer, takes n root to both pass through the benchmark of central point N in foundation pit earth face
Line, n >=3, the angle per adjacent two foundation directrix is equal and is δ, δ=180 °/n, two ends of all reference lines and foundation pit
Edge all has an intersection point, respectively takes a midpoint as measurement point, central point on central point N to the line section between all intersection points
N is also measurement point.
Further, reference line radical n=3, δ=60 °, two ends of reference line and the intersection point of margin of foundation pit be respectively A,
B, C, D, E, F, respectively take its midpoint A1, B1, C1, D1, E1, F1 on line segment NA, NB, NC, ND, NE, NF respectively, midpoint A1, B1,
C1, D1, E1, F1 and central point N are measurement point.
Further, be marked after having chosen central point N in the point, then draw graticule pass through central point N until
Graticule both ends and margin of foundation pit have intersection point A, B, are fixed graticule with timber in two intersection point A, B location, repeat above-mentioned behaviour
Make to pass through central point N with two graticules again, angle is 60 ° between adjacent two graticule, and the intersection point of two graticules and margin of foundation pit
Respectively C, D, E, F are fixed corresponding graticule with timber in the position intersection point C, D, E, F, then measured on three graticules NA,
Midpoint A1, B1, C1, D1, E1, F1 of NB, NC, ND, NE, NF, and marked in midpoint A1, B1, C1, D1, E1, F1.
Further, after having chosen measurement point, the reading of each measurement point is measured by air-bubble level, and is done easy to remember
Record.
Further, the sensitivity for selecting air-bubble level is 0.3mm/m or 0.4mm/m.
Beneficial effects of the present invention are as follows:
1, when choosing measurement point, the native face central area first after filling optionally takes a central point N as datum mark,
Central point N is also one of measurement point simultaneously, then takes n root to both pass through the reference line of central point N in foundation pit earth face, obtains for guarantee
Multiple groups correlation data, reference line are at least arranged three, and two ends of reference line and margin of foundation pit obtain an intersection point, central point N
It respectively takes a midpoint as measurement point on to the line section between all intersection points, to obtain all measurement points, is obtained according to this method
The measurement point distribution arrived is uniform, has broken randomness, measurement is more scientific, to guarantee the accuracy of measurement result.
