Below provide some specific embodiments as aid illustration.
Embodiment 1:
Be positioned at Yunfu City transformer station, 180 millimeters thick enclosure walls and 59 equipment of 292 meters of length are arranged in the power station.Wherein the weight of equipment is 0.7 ton and does not wait to 1.0 tons; Make footing beam under the brick enclosure wall of 180 millimeters thick, per 5 meters pillars, totally 60.Because the face of land is not waited for 1 to 3 meter and is backfill, it is infeasible directly to do the direct foundation, need do the ground processing.And, one side the power station close on a fish pond, a stake machine can not get into.In this case, it is lower that we have expected that the job site requires, and job practices is octagonal pile more flexibly.
We have also contrasted two kinds of foundation treatment modes quality economically simultaneously:
1. 250x250 precast concrete square pile: only make friction pile and consider, 1 of the following needs of every enclosing wall column, but the requirement of consideration bending resistance square, the result wants two; Do one under every Equipment Foundations, by every 870 yuan of calculations, meter stake machine admission fee 60000 yuan (place is remote) adds up to 215730 yuan of investments in addition.
2. octagonal pile: only make friction pile and consider that cloth is two under every enclosing wall column, does two under every Equipment Foundations, long 5 meters of root, 1 meter of pile follower by every 50 yuan of calculations, adds up to 11900 yuan of investments.
Be because the restriction of job site is the consideration from economic factor on the one hand, and we confirm to select for use octagonal pile at last on the one hand, this power station enclosure wall, Equipment Foundations are accomplished has had nearly six months so far, and mode of occupation is good.
Embodiment 2:
An interim agitator that is positioned at moral famous scenic spot, Shuande district requires to do ground and handles, and this area's geological condition is relatively poor, and the top layer weak soil covers thicker.In application for developing, we make following assessment:
Handle if do the castinplace pile that dusts, by every square metre of distribution, need 100, every long 6 meters, considers by the cost of 50 yuan every meter of the stakes of dusting, and needs 30000 yuan of investments; As use octagonal pile instead, according to every square metre of 4 distributions, stake is long to be similarly 6 meters, considers by every 55 yuan costs, needs 22000 yuan of investments.It is thus clear that it is under the situation that effectiveness equates, select octagonal pile to reduce investment outlay relatively, and reliable.In the piling process, know the effect that ground is handled immediately, can on-the-spot quantity and the length that increases or reduce stake, also needn't as other, do detection.
Embodiment 3:
Be positioned at one small electrical room, Shuande, need make ground and handle, compare two feasible programs below:
As select for use the direct foundation to press down timber, and need 60 of 5 meters long φ 120 pine stakes, by every 70 yuan of calculating of 5 meters timbers, purchasing stake needs 4200 yuan; As use octagonal pile instead, by every 50 yuan of calculating of 5 meters long octagonal piles, purchasing stake needs 3000 yuan.It is thus clear that only the investment aspect stake has just economized 29%.Moreover this area termite is serious to the erosion of timber, and timber can not be ignored by other factor corrosion phenomenons; By contrast; The pile quality of octagonal pile uses much more stable than timber, and intensity is much bigger, and the use of saving timber also is the environmental protection of advocating now.
The above is merely preferential embodiment of the present invention, as long as realize that with basic identical means the technical scheme of the object of the invention all belongs within protection scope of the present invention.
