Abstract
The invention discloses a construction process for a foundation. The construction process comprises the following steps of: injecting instant coagulability mortar or turbid mortar serving as a primary injecting material to fill a coarse part of the foundation; and injecting mortar serving as a secondary injecting material and prepared by mixing water glass, sodium phosphate, slaked lime, sand and water. The mortar can form an elastic layer, the elastic layer can be firmly adhered with a rigid concrete layer to form a compact structure having elongation, elasticity and toughness, and the formed foundation platform has certain bounce capacity, can consume impact energy of seismic waves to isolate the destructive power of the seismic waves on buildings on the ground, and has a good application prospect.
Description
Technical field
The present invention relates to the realm of building construction, be specially a kind of foundation construction technology that strengthens the Antiseismic building performance.
Background technology
Earthquake is the general name of internal force geologic process and the external force geologic process crustal shock phenomenon that can cause, it is a kind of natural phenomena of crustal movement when taking place sharply to change in some stage.The size of one earthquake depends on the energy of release, representes with earthquake magnitude, and earthquake intensity then is the suffered damaged condition of reaction surface structures.
China is the multiple country of an earthquake, and only the sixties in last century rely on, and the earthquake wine more than 7 grades has taken place repeatedly; Xingtai earthquake particularly, Tangshan earthquake, nearest Wenchuan earthquake and cajaput earthquake; All occur in the densely populated area, caused serious loss to the people's lives and property.How carrying out shockproof, antidetonation is the eternal difficult problem of pendulum in face of the people of the world, particularly modern metropolis, and high buildings and large mansions stand in great numbers, in case run into earthquake disaster, these high buildings and large mansions will become piles and piles of rubble in seconds.The disaster of being brought in order to reduce earthquake as far as possible, people constantly improve on fabric structure, further improve its shock resistance, especially to the processing in different bases.Ripe at present method for processing foundation is a lot; Like consolidation, grouting and reinforcing method, displacement method and compacting method etc.; These methods all have the pluses and minuses and the scope of application separately, and the foothold of these methods all is how to improve the bearing capacity of ground and the bulk strength of building, but facts have proved; Their drawback is because the concrete of being poured into a mould in the construction processing process is rigid concrete; The ground based platform lacking toughness, no springback capacity, the rupture strength that make to constitute are low, can't absorb seismic wave, in case when running into earthquake; Seismic wave reaches ground building along underground ground based platform with seismic wave, and ground building can't be resisted and collapse.
Summary of the invention
The concrete that the present invention pours into a mould for the method for processing foundation that solves existing building is a rigid concrete; Make that the ground based platform lacking toughness, no springback capacity, the rupture strength that constitute are low; Can't resist the problem of earthquake disaster, a kind of structure foundation construction technology that can eliminate earthquake disaster is provided.
The present invention adopts following technical scheme to realize: 1. foundation construction technology; Its step comprises in ground injects flash set property mortar or outstanding turbid type mortar as an injection material; After filling the coarse part of ground; As the secondary injection material, inject the mortar that mixes by water glass, sodium phosphate, hydrated lime, sand and water.Method for processing foundation according to the invention can be used with existing ripe method for processing foundation, and flash set property mortar that is adopted or outstanding turbid type mortar also are that those of ordinary skill in the art knows.
In a preferred implementation of the present invention, contain water glass 40-60kg, sodium phosphate 5-15kg, lime 60-150kg in the mortar per ton, sand 300-600kg, wherein the average grain diameter of sand is 1-3mm.
In a preferred implementation of the present invention, it is characterized in that containing in the mortar per ton water glass 50kg, sodium phosphate 10kg, lime 100kg, sand 400kg, wherein the average grain diameter of sand is 2mm.
In a preferred implementation of the present invention, it is characterized in that the Na of described water glass
2O and SiO
2Mol ratio is between 4-5, is preferably between the 4.5-4.8, further is preferably 4.7.
The present invention also relates to above-mentioned mortar and this mortar in addition on the one hand in the application that improves in the earthquake intensity of ground antidetonation.
The thickness of said elastic concrete layer is 0.3-0.6m, in this thickness range, and both rheobase requirements contentedly, the impact force that can resist seismic wave again.
The specific embodiment
Embodiment 1:
A kind of structure foundation construction technology that can eliminate earthquake disaster; Its step comprises in ground injects flash set property mortar or outstanding turbid type mortar as an injection material, behind the coarse part of filling ground, as the secondary injection material; The plaster material that the ground of cast below injecting is used is by Na
2O and SiO
2Mol ratio is the mortar that 4.7 water glass, sodium phosphate, hydrated lime, sand and water mix; Contain water glass 50kg, sodium phosphate 10kg, lime 100kg in the mortar per ton; Sand 400kg, wherein the average grain diameter of sand is 2mm, mortar thickness is 0.4m.Treat to detect aqueousization degree and the antidetonation earthquake intensity of ground after the mortar setting 2 days, through detecting liquidity index more than or equal to 0.75, anti-earthquake intensity is spent greater than 8, meets seismic design provision in building code GB5011-2010.Compared with prior art, mortar of the present invention can form elastic layer, firm the boning with the rigid concrete layer of this elastic layer ability; The formation structure is closely knit; Have elongation per unit length, elasticity and toughness, and compressive strength can reach the concrete structure that 60Mpa, rupture strength bring up to four times of compressive strength, make the ground platform that forms have certain springback capacity; Can be with the impact energy consumption of seismic wave; Guaranteeing isolator seismic wave,, has good application prospects for the structure foundation construction has solved the great difficult problem that is difficult to overcome always to the destructive power of building on the ground.
When being understood that, the above-mentioned specific embodiment only is an illustrative, concerning those of ordinary skills, can improve or conversion according to above-mentioned explanation, and all these improvement and conversion all should belong to the protection domain of accompanying claims of the present invention.
