Description
Technical field
The present invention relates to a kind of building lot, specifically a kind of building waste ground-slag concrete stake and method for processing foundation thereof belong to the building lot field.
Background technology
Along with the raising and the industrialized development of national economy, existing building all has a lot of buildings need remove reconstruction because of reaching the problem of rationally utilizing aspects such as soil data at function, the time limit every year, and the building waste of generation will get more and more.The quantity of China's building waste has accounted for about 40% of municipal refuse at present, and the pollution that building waste produces is equivalent to the twice of motor vehicle emission tail gas.The harm that building waste brings has obtained the abundant attention of all circles.Yet the building waste that building produced is because of the difference of various types of composition and content, thereby need distinguish utilization according to its performance.Urban architecture is at present removed rubbish and generally mostly is brick mix structure, brickbat and the mortar of the rubbish that is produced nearly 80% for building a wall and forming, nearly 10% concrete block.
At present, it mainly is to use concrete wherein to make regeneration aggregate that building waste utilizes again, produce the concrete brick and be used for the not high positions of compressive strength such as roadbed, foundation pad and non-structural part, thereby consumption is little, and the scope of application is narrow.The regeneration aggregate of producing is to process after crushing and screening cleans with the concrete in the building waste basically; But a large amount of concrete pieces and mortar do not obtain utilizing yet; Mainly be because the intensity of brick body is low; The regeneration concrete aggregate of making is difficult to meet the requirements of design strength, so very most building waste can not be utilized.
Low-intensity rammed concrete pile foundation treatment technology is widely used in the construction works such as railway, highway and house, uses that structure foundation bearing capacity after this technical finesse is high, distortion is little, and it is low to handle cost, thereby is widely used.Low-strength cement soil stake is in Ground Treatment, because the acting in conjunction of stake and soil, its pile body is stressed little, so low to the compressive strength of the cement-soil of pile body requirement.The compressive strength of cement-soil is generally at 1-5MPa, and consumption is big, and in order to reduce the distortion on road, all full hall arranges that the stake diameter is in 500 millimeter like speedway, railway etc., and consumption is big, requirement of strength is low.
Summary of the invention
In order to address the above problem, the present invention has designed a kind of building waste ground-slag concrete stake and method for processing foundation thereof, and this method is through pulverizing, sieve building rubbish; Process rubbish ground-slag concrete stake then, carry out long auger at last and ram and to fill into stake, adopt the structure foundation bearing capacity after this method identical with the effect of the former raw material of use; Be out of shape for a short time, and it is low to handle cost, provides cost savings; Improve the effective rate of utilization of refuse, realized economic benefit.
Technical scheme of the present invention is:
A kind of building waste ground-slag concrete stake comprises cement and building waste ground-slag, and described building waste ground-slag is a particle diameter less than 2 millimeters building waste ground-slag particle; The mass ratio of described cement and building waste ground-slag is 1 ︰ 6～8, and said building waste ground-slag concrete stake compressive strength is 1-5MPa.
A kind of method for processing foundation of building waste ground-slag concrete stake may further comprise the steps:
(1) with the building rubbish of removing comprise brick, watt, the piece material of stone, concrete pulverizes, sieves; Obtain particle diameter at 5～40 millimeters building waste coarse aggregate and particle diameter building waste fines, and remaining particle diameter is less than 2 millimeters building waste ground-slag particle at 2～5 millimeters; Particle diameter is used to prepare the plain concrete stake of building refuse regeneration aggregate at 5～40 millimeters building waste coarse aggregate and particle diameter at 2～5 millimeters building waste fines;
(2) particle diameter that above-mentioned steps (1) is obtained is less than 2 millimeters building waste ground-slag particle and the cement mixed according to mass ratio 1 ︰ 6～8;
(3) boring is rammed and is filled into stake, comprising:
3.1 boring:, hole through a kind of mode in immersed tube, impact, luoyang spade, the auger according to the requirement of architectural design;
Be drilled to the hole 3.2 carry: carry brill after the degree of depth that reaches the architectural design requirement of holing, carry the drilling speed degree and want evenly slowly, speed controlling obtains a hole at 1.2-1.5m/min;
Fill out 3.3 ram in the hole: compacting before the filler of stake hole, the rammer on stake top are filled out aspect ratio design stake heights of roofs and are exceeded the 200-300 millimeter, stake end face level; The rubbish ground-slag concrete stake material that above-mentioned steps (2) is obtained is filled in the hole, mechanical then segmentation compacting pile hole, and coefficient of consolidation is greater than 0.95; Stake hole centre deviation is no more than 1/4 of stake footpath design load, and the vertical degree of the peg hole deviation is less than 1.5%, and the stake bore dia is greater than design stake footpath, and the stake hole depth is dark greater than projected depth, obtains the rubbish ground-slag concrete stake of compressive strength at 1-5MPa.
The brick-and-concrete buildings rubbish green strength of removing is generally more than 7.5 MPa; Through broken and screening back according to different particle diameters, particle diameter is used as the concrete of regenerating at 5～40 millimeters building waste coarse aggregate and particle diameter at 2～5 millimeters building waste fines coarse aggregate and fines; Obtain particle diameter after the screening less than 2 millimeters building waste ground-slag particle; Add cement and make compacting concrete stake material; Be used for requirement after treatment low building of bearing capacity also can satisfy designing requirement, calcium oxide combines to react with silicon property material in the cement, and the pile strength of cement can be provided; The excellent cement of pile quality is practiced thrift cement simultaneously with the cooperation of soil.
The invention has the advantages that: solved the problem that most of building waste can not be fully utilized; Building waste ground-slag particle is applied to building lot, building waste is fully used, developed a new way that makes full use of building waste; Can be widely used in the construction works such as railway, highway and house; Structure foundation bearing capacity after employing the inventive method can reach the requirement of architectural design fully, and it is low to handle cost, provides cost savings; Improve the effective rate of utilization of refuse, realized economic benefit.
