Computation of cubic meter of earth notes a drop unexpectedly so much, pardonable be opposite every

Answer fill

? Concept and computation are regular

01- field backfill: The backfill in pointing to level field is average ply exceeds 0.3m

02- indoor backfill: It is to point to above of level ground of the ground outdoor to fill up the backfill between the layer to indoor ground normally, also call room heart backfill earth

03- foundation backfill: Cent is element earth backfill and grey earth backfill.

Grey earth backfill: Element earth adds lime, it is grey earth, according to how many minutes of 2:8 of limeGrey earth, 3:7Grey earth. Grey earth has higher intensity and water-resisting property, grey earth gradually sclerotic, increased the adherent strength between edaphic grain, can raise the packing of backfill earth at the same time, the action of grey earth backfill is to prevent groundwater external of the wall erode. The certain limits that stands by retaining wall commonly (specific by blueprint or project feature is described) the earth that use ash, element land is used beyond, following plan institute show:

Element earth backfill: What do not add lime is element earth.

? Wide couplet amounts to fact of software calculating an amount to hold

Backfill of 01- room heart

The ply that decorates a practice according to ground of first each room and room inside and outside differ high quite, the ply of earth of room heart backfill that computation gives each rooms, ordinal definition (ply of the input in room name, property is being taken in naming) , stipple (the attention uses empty wall space)

If plan institute shows the ply of floor tile ground to be 135mm, tall difference of level ground of indoor other place is 450mm, so the room of floor tile ground is at ease the ply of backfill is 450-135=315mm

02- foundation backfill

1, element earth backfill: There should be grey earth backfill in the project, when having element earth backfill only, when the interface that fill up a layer creates cubic meter of earth, need not tick off those who choose grey earth backfill, the graph that also does not have backfill of alone element earth yuan;

The project amount need of element earth backfill pursues in cubic meter of earth yuan in examine, pursue as follows:

2, grey earth backfill

If grey earth backfill is perpendicular,direction has a kind of land only, can mix the middle-level in attribute of grey earth backfill the ply of a layer is defeated 0, the total ply that inputs backfill in ground floor only can, the deepness of the ply of general backfill and excavation is consistent.

Want to tick off those who chose grey earth backfill only, the meeting is automatic while software creates cubic meter of earth automatically the component part that makes grey earth backfill pursues yuan, namely the project amount of grey earth backfill is in backfill of big excavate grey earth or base backfill of groovy grey earth, base the extraction in backfill of hole grey earth;

Right now element earth backfill is bulk it is to deduct with bulk of grey earth backfill

Note a drop: Working face of grey earth backfill is wide

It is to give out on blueprint certain ply uses the wall outside basement 3: Backfill of 7 grey earth is statified tamp, and there is working face only when generating grey earth backfill, the ply requirement of the grey earth backfill in noticing not to want a blueprint fills in directly the position in working bizygomatic breadth, the graph below the basis can understand both distinction.

Summary: The working bizygomatic breadth of grey earth backfill also calculates since the edge that fill up a layer, the wall outside basement of and rather than, it is certain that the wall outside be apart from gives out in blueprint so ply, whether does balsa board foundation have in the working surface basis that backfill of will grey earth needs when actual software is operated outside extend, fill up an edge of the layer to wait to calculate instead.

? Backfill earth covers a note (12 budgetary norm of Beijing)

Undertaking covering when, backfill earth wants the material of divisional earth to pledge, also need to consider cubic meter of earth to answer carry at the same time

[12 budgetary norm of Beijing]

1, backfill earth answers carry to carry out the 4th cubic meter of earth to answer less than of 1km of carry haul distance and every to add 5km norm specific item.

2, the fare that land buys outside including in specific item of norm of backfill of cubic meter of earth, when happening, calculate separately.

More than discard

? Concept and computation are regular

? Wide couplet amounts to fact of software calculating an amount to hold

Wide couplet amounts to GCL2013 to calculate quantity software, the carry outside Yu Tu need not scale, in forms for reporting statistics, the project raises an amount directly in integrated index watch, but those who need an attention is, carry Yu Tu is to did not deduct room heart backfill, if have room heart backfill, need measures room heart backfill the hand to move with earth deduct.

GTJ2018 considers quantity software medium to do not have relevant forms for reporting statistics at present, need authority so manual uses the formula above,

Bulk of excavation of Yu Tu = - backfill earth - room heart backfill

? More than discard covers a note (12 norm of Beijing)

Undertaking covering when, more than discard needs to consider Yu Tu outside carry distance, the actual haul distance that carries outside cubic meter of earth is inputted directly in standard conversion can. Notice Beijing proposes a standard [2017] the need after 27 article is covered according to newest norm, carry outside field of cubic meter of earth included carry and accept of disappear of cubic meter of earth.

? Wide couplet amounts to software calculating an amount to operate common problem and processing train of thought

Problem 1: Between type of different folk recipe deduct a relation, when creating cubic meter of earth automatically, intersect via often having between can different folk recipe, after all whose first step is bigger?

Wide couplet amounts to the first step of component of the cubic meter of earth in software to be: Big excavate ＞ base hole ＞ base groove;

Base bulk of hole cubic meter of earth deducts big excavate cubic meter of earth; Base bulk of groovy cubic meter of earth deducts big excavate, base hole cubic meter of earth.

Problem 2: Big excavate and base the difference that tunnel project measures?

Circumstance of the coefficient that put slope falls, big excavate and base tunnel project amount is indiscriminate, but build component part apart as far as possible, collect project amount in order to go to the lavatory;

As a result of base hole and cubic meter of earth (big excavate) ply of the convert that put slope (pursue as follows) abhorrent, calculating according to convert ply so when cubic meter of earth, project of cubic meter of earth of Fang Heji hole measures big excavate land is discriminating.

Attention: Inclined balsa board (the position such as ramp) only ability of big excavate cubic meter of earth forms underside to pursue for inclined cubic meter of earth yuan, base hole cubic meter of earth cannot generate underside to pursue for inclined cubic meter of earth yuan, if this position is judged,so is base hole cubic meter of earth, also want big excavate cubic meter of earth to replace, hand of the need when later period raises an amount is moved divisional.

Problem 3: When creating cubic meter of earth, it is certain to can have between cubic meter of earth intersect, so intersect what kind of is deducting a relation?

Between cubic meter of earth intersect cent is two kinds of circumstances, put slope to the part overlaps and be not the part that put slope to also intersect only.

Problem 4: Alone base or when look is closer, it is big excavate still is dug base hole or base groove

Occasionally form foundation or independent base also can do big excavate folk recipe, ponder over spot construction case more.

Software processing: Need not create cubic meter of earth automatically, build component part of big excavate cubic meter of earth alone, had compiled property information, direct scale gives the appearance of big excavate cubic meter of earth, if the working face of each edges perhaps puts slope coefficient to have a difference, the function that can use setting working face and setting edge slope undertakes modification alone to a certain edge.

Problem 5: GCL2013 calculates what catchment pit brings in measuring software to feel when generate those who generate is incorrect, some range that exceed big excavate, need not to need to handle?

To balsa board the foundation has base this kind of circumstance of puddle, meet first in actual project commonly integral excavate, of part of the again local on the foundation of big excavate water hole that dig collect base hole cubic meter of earth;

GCL2013 considers quantity software medium, general on the offensive moves those who generate big excavate second birth to become catchment hole base hole cubic meter of earth, but make catchment hole base when hole cubic meter of earth, all cubic meter of earth can create the level of level ground of the ground outdoor automatically;

If the cubic meter of earth of catchment hole and big excavate intersect, can deduct automatically, need not do processing right now.

If the cubic meter of earth of catchment hole exceeded the range of big excavate (the cubic meter of earth that is like position of right small part) , it is much that cubic meter of earth of hole of this time base calculates an amount, so need adjusts the cubic meter of earth of here catchment hole, the cubic meter of earth of the collect pool that pitch on builds revises his to carry elevation on the head, it is the ground level of big excavate commonly. The collect water hole that puts slope quadrilateral namely inclined catchment hole, working surface is defeated commonly 0.

GTJ2018 calculates the software in measuring software to generate cubic meter of earth to make level ground of the ground outdoor no longer, but also need everybody to check top elevation and working face.

Problem 6: The processing of backfill of cubic meter of earth that has basement notes a drop

Have the project of basement, a lot of friends handle train of thought two kinds from time to tome in processing, following

Need decorates basement room did, build a room to decorate namely can, the project of the computational foundation backfill with software accurate ability is measured, also can calculate inside basement room limits otherwise for backfill of cubic meter of earth

Do not need special processing, software can deduct the interior space of basement automatically

Enlightenment: As far as possible basement and fundamental layer departure are built, do not build in one

Of course to cubic meter of earth the processing of relevant component everybody the method may be different, I just nodded my train of thought and attention to everybody to share below, if have inappropriate place reception,everybody criticizes point out mistakes so that they can be corrected.
