Abstract
The invention relates to a construction method for building foundations, and particularly relates to a construction method for an earthquake-proof foundation. The inventor thinks that rocks under the building are not a whole body, gaps exist among large rocks and small rocks, the small rocks fall downward from the gaps during earthquake, and then the original flat foundation becomes uneven, forces acting on all parts of the building are not even, the structure of the building is broken, and the building is cracked and collapses. The technical scheme of the invention has the characters: the range of construction is 30-50% greater than the building in the length direction and the width direction; a ground pit is dug; hole drilling is performed on the ground pit bottom soil at an interval of 0.5-3 meters in the length direction and the width direction; and a permeation material is injected into the holes, and the permeation material is added in the gaps under the bottom soil. In this way, the gaps are filled with the permeation material, the large rocks and the small rocks are stable during earthquake, the foundation keeps even, and then the safety of the building can be ensured.
Description
Technical field
The present invention relates to a kind of structure foundation construction method, particularly relate to the construction party of constructure shakeproof ground
Method.
Background technology
The problem that the shockproof process of building is always architectural engineering circle special concern.It is generally acknowledged that building is tied
Structure is reasonable, and uniform force, building is the most firm on hard rock simultaneously.So architectural engineering
Shockproof technology is focused in the structure of building self and the combination of building basis and rock by boundary.But
Studying violent earthquake in recent years and find, some building buildings on solid rock still there occurs and collapse,
Structure has carried out the building of shockproof process and has also occurred in that situation about collapsing.Present inventors believe that large and small rock
There is gap between stone, thus rough situation is that building collapses to cause ground to occur when earthquake
Reason place.
Summary of the invention
For solving above-mentioned technical problem, solving ground and occur rough situation when earthquake, the present invention adopts
Use following technical scheme: the construction method of a kind of constructure shakeproof ground, construct according to following program:
(1) scope many 30-50%s more each than the length and width direction of building on length and width direction of construction are chosen；
(2) excavation of foundation pit is carried out within the above range；
(3) dig to foundation ditch subsoil；
(4) foundation ditch subsoil is respectively holed with 0.5-3 rice for interval on length and width direction；
(5) penetration material is poured in hole, with the gap under penetration material filling subsoil.
The present inventor is to collapse in 5.12,4.20 violent earthquakes building and ground thereof, and periphery geological condition
Carry out on-the-spot investigation and conscientious analysis and research, found that earthquake field has following three kinds of phenomenons:
1, according to the narration of survivor, during earthquake, in start to rock ten seconds, do not have massif to collapse and build
The situation that thing collapses, but the sound that when having similar massif to collapse, rock mutually clashes into, this sound is from room
Under toft plinth.Inventors believe that these sound just, illustrate to have between rock gap.Shaking disorder of internal organs,
Mutually collision is occurred to produce the sound of shock between rock.
2, after earthquake, ground occurs in that rough phenomenon, some places rock have exceeded ground, some ground
Square then recessed go down.Inventors believe that earthquake is rocked the bigger place of rear rock and exceeded ground, and rock
Less place is recessed goes down.
Subsoil water is had to emerge when 3, rocking.Inventors believe that, less rock is fallen by gap at rolling disorder of internal organs
To deeper inside, thus occupying the space of subsoil water, subsoil water is had to upwards gush out.
In sum, inventors believe that the rock under these buildings is not an entirety, in big rock week
While be mingled with rocklet, between large and small rock, have gap, through deposition for many years, the biggest rocklet it
Between keep relative stability, building is built thereon, and safety can ensure that, even meeting small earthquake by chance.
But when running into larger earthquake, due to the existence in gap, rocking through earthquake, rocklet can by gap to
Under drop so that rough phenomenon occurs in the most smooth ground, cause building stress everywhere not
All, structure is destroyed, and cracking collapses, and this is only the basic reason of damage of building in earthquake.This existing
As in our daily life also often it can be seen that.Such as, family life pours salt or sugar into bottle,
If our shake bottle again after filling, we can find that the salt in this bottle or sugar have gone down again some,
Bottle again can fill some salt or sugar again more, and this explanation is to have gap between these salt grains or sugar grain before shake
's.For another example, we pour numerous less stones into a basin, place into several bigger stone, so
After repave last layer finger stone, be allowed to can't see from the teeth outwards the stone of bulk, but when we shake basin or
After person rocks basin, we can find that the stone of bulk can be emerging in surface, and this explanation through shake or is rocked,
Gap between stone eliminates or partially removes, and finger stone goes down, thus exposes ratchel, or
Ratchel has been encircleed out in dither process by finger stone.
Based on above-mentioned principle, inventors believe that it is the elimination in gap between large and small rock, little rock in earthquake
Dropping of stone, result in the injustice of ground so that building force structure is unbalance, and stress concentrates on building
Certain point, first result in this dot structure and be destroyed, thus cause chain reaction, last building collapses.
To this end, present inventors have proposed above-mentioned engineering techniques, to solve the shockproof problem of building.
By above-mentioned engineering techniques, can fill under foundation ditch subsoil between large and small rock with penetration material
Gap, on the ground so processed, carry out building the most again.Through such process, big,
Gap between rocklet is saturated material and tamps.When earthquake is rocked, between large and small rock, keep the most steady
Fixed, it is ensured that structure foundation does not haves rough situation, it is ensured that building stress everywhere
Equilibrium, structure will not be destroyed, thus ensures the safety of building.
The present inventor also above engineering techniques has been carried out easy simulation contrast experiment:
Experiment 1: put into some finger stones in basin, then the stone that three bigger is embedded in centre, rocks
Basin about ten seconds, three bigger stones, expose surface.
Experiment 2: with the same method filling stone of experiment 1, be subsequently poured into sand, with water, sand poured seam
Among gap, after water is dry, rock basin by same method, it can be seen that three bigger stones do not have
Exposing surface.
Based on above-mentioned experiment, it can be seen that the engineering techniques of the present invention is effective.
Further technical scheme: described penetration material is sand or connects sandstone or cement mortar or concrete.
