Abstract
The invention relates to the field of building construction, in particular to a foundation treatment method of buildings, which can eliminate earthquake disasters and solve the problems that the existing building foundation poured by rigid concrete has poor toughness, no modulus of resilience and low bending strength and can not resist the earthquake disasters. The foundation treatment method comprises the following steps of: leveling the rigid concrete layer, and then pouring a layer of elastic concrete which is prepared by Portland cement, sand, cobbles, a concrete complexing agent, bromine, rubber particles and an elastic additive. The elastic layer can be bonded with the rigid concrete layer firmly, forms a concrete structure which is compact, has elongation rate, elasticity, toughness, pressure strength of 60MPa, improves bending strength by four times than the pressure strength, leads the foundation platform to have modulus of resilience and can consume the impact energy of earthquake waves so as to guarantee to isolate destructive force of the earthquake waves to the buildings on the ground and solve a big problem which is difficult to overcome for the construction of the foundation of the building.
Description
Technical field
The present invention relates to the realm of building construction, be specially a kind of foundation treatment method of buildings that can eliminate earthquake disaster.
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 some stage generation sharply changes, how carrying out shockproof, antidetonation is the eternal difficult problem of pendulum in face of the people of the world, particularly modern metropolis, 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, as consolidation, the 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 common drawback is because the concrete of being poured into a mould in the construction processing process is rigid concrete, the feasible ground based platform lacking toughness that constitutes, no springback capacity, rupture strength is 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 foundation treatment method of buildings that can eliminate earthquake disaster is provided.
The present invention adopts following technical scheme to realize: the foundation treatment method of buildings that can eliminate earthquake disaster, its step is included in cast rigid concrete layer on the foundation soil behind the excavation, after the levelling of rigid concrete layer, pour into a mould one deck elastic concrete more thereon, described elastic concrete is to be made by the raw material of following parts by weight: portland cement 400-480kg, sand 635-655kg, stone 1050-1350kg, composite concrete agent 60-72kg, bromine 12-14.4kg, rubber grain 28-33.6kg, elastomeric additive A group powder 20-57.6kg, B group liquids 12-24kg.The consumption of above-mentioned each component can enlarge according to the amount equal proportion of required concrete batching or dwindle.Method for processing foundation of the present invention can be used with existing ripe method for processing foundation, and this is that those of ordinary skill in the art is known.
In the above-mentioned prescription, described Portland cement can be the cement of labels such as commercially available P.O425, P.O325, P.O525, preferred No. 525 Portland cements of conch board; Sand can be the river sand of Xuzhou product at least; Granite stones that stone can be shown no increases in output for the Shanxi Province is former at least or limestone rock ballast, particle diameter are 1-5cm; Described composite concrete agent is this application people in the patent No. is disclosed prescription in 200610102246.5 the application documents, be specially silica 48-55%, fluorite 27.5-45%, cetyl benzene sulfonic acid sodium salt 2.5-8%, hydroxycarboxylic acid 4-9%, aliphatic hydroxyl sulphonate high efficiency water reducing agent 0.5-1%, can improve the particle bonding bond stress of elastic concrete aggregate, improve slump, improve concrete compressive strength and rupture strength, make the compressive strength of this elastic concrete reach 60Mpa; Described bromine can be the bromine that Qingdao produces at least, utilizes the flame-retarding characteristic of bromine itself, makes elastic concrete of the present invention become the anti-flaming product of fire prevention, eliminates disaster hidden-trouble; Described rubber grain can increase concrete elasticity and pliability, increases the springback capacity of elastic concrete layer, and this rubber grain can obtain by pulverizing scrap rubber or waste rubber product; Described elastomeric additive is this application people in the patent No. is disclosed prescription in 200510012490.8 the application documents, it comprises A group powder and B group liquids, A group powder prescription is as follows: silica 65-75%, hydroxycarboxylate 2-10%, agstone 10-20%, dispersing agent 0.1-0.8%, water reducing agent 0.05-0.2%, rubber powder 3-6%; B group liquids prescription is as follows: the polyacrylamide of 20-300 gram adds in 100 premium on currency and stirs, make polyacrylamide solution, the polyethers of 10-200 gram adds in 100 premium on currency and stirs, make polyethers solution, polyethers solution and polyacrylamide solution are with 1: 2-4 mixes and stirring obtains B group liquids, this additive joins in the concrete of the present invention, disclosed consistent in its mechanism of action and the above-mentioned patent document, other component in this elastomeric additive and the concrete formulation of the present invention cooperatively interacts, make concrete rupture strength bring up to four times of compressive strength, further improved concrete durability.
The thickness of described 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 particle diameter of described rubber grain is 1-3mm; The soil that contains in the described sand is measured less than 3%, otherwise can influence concrete particle adhesion stress.
Compared with prior art, the elastic concrete that cast is filled a prescription as described herein on the rigid concrete that the present invention pours into a mould in the ground foundation ditch, firm the boning of this elastic layer energy with the rigid concrete layer, the formation structure is closely knit, has elongation per unit length, elasticity and toughness, and compressive strength can reach 60Mpa, rupture strength is brought up to the concrete structure of 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, to guarantee that seismic wave is to the destructive power of building on the ground isolator, for the structure foundation construction has solved a great difficult problem that is difficult to overcome always, has good application prospects.
