Abstract
The utility model relates to a double-column lining structure for a double-circular shield tunnel. The lining structure adopts two pipelines shaped like circular rings and is made up of two columns, four single-wing block with identical specifications, as well as more than two standardized blocks, wherein two columns are erected between the two circular rings, the two single-wing blocks are positioned at the top parts of the two columns after combination, and the other two single-wing blocks are positioned at the bottom parts of the two columns after combination. The single-wing blocks and thestandardized blocks are assembled in sequence to form closed double rings; pre-buried ductile cast iron hand holes and nuts among the standardized blocks as well as among the standardized blocks andthe single-wing blocks are fixedly connected by using single-head short and straight bolts; the straight bolts among the single-wing blocks are fixedly connected by using nuts in a manner of respectively passing through the prepared trapezoid hand holes of the two blocks and the straight bolt holes; and a rubber water bar capable of expanding after meeting water is adopted for seam water prevention. The utility model has the advantages that the integral seismic performance of the double-column lining structure is superior to that of the single-column lining structure, an effective pathway is formed between the double columns so as to enable people to disperse successfully after occurrences of safe accidents; and the pathway between the double columns can be used for storing daily maintenance equipment, thereby facilitating tunnel maintenance.
Description
Technical field
The utility model relates to the construction of tunnel technical field, specifically is the upright post lining structure of double in a kind of double-O-tube shield method tunnel.
Background technology
The shield tunnel technology since have little to surrounding environment influence, adapt to advantages such as various stratum and different buried depth, mechanization of building operation degree height, speed are fast, safety height, in the urban compact district with pass through under water and obtained in the construction of building construction of tunnel widely using, it is regional very widely particularly to distribute at weak soils such as Shanghai, Guangzhou, has more the unique technique advantage.Along with shield structure technology is perfect day by day, earth pressure balanced shield, EPBS, mud balance shield have been widely used in the shield-tunneling construction city underground in China.Japan's construction of tunnel circle proposed the imagination of double-O-tube shield tunnel in 1981.Double-O-tube shield is in shape just as two conjuncted single targe structures, and it just can finish two tunnels by once advancing.Double-O-tube shield tunnel has that the underground space of taking is little, efficiency of construction is high, the native amount of digging less, advantage such as section effective rate of utilization height, engineering cost be low.The construction technology of two circular tunnels was studied by Japan in 1987, and had carried out the construction of first the double-O-tube shield in the world at Hiroshima,Japan in 1989.Through the development of more than ten years, the design of double-O-tube shield, manufacturing technology are perfect day by day, have successively built 11 double-O-tube shields in Japan, have built up 6 two circular tunnel rail lines.The yellow emerging green floor site of Shanghai rail transit M8 line to way station of Xiang Yin Dynasty running tunnel is the tunnel of Chinese first strip adoption double-O-tube shield machine tunneling construction.This running tunnel formally tunneled since on August 8th, 2003, was open to traffic on December 31st, 2003.China becomes second country that uses the double-O-tube shield machine to finish tunnel piercing in the world thus.
Find through literature search prior art, Chinese patent application number: 03115651.7, denomination of invention: the liner structure in double-O-tube shield method tunnel, publication number: CN1470742, this patent readme is: " shape of this liner structure is two crossing circular pipelines; mainly by big flying bird piece; little flying bird piece; column piece and the calibrated bolck more than two constitute; wherein big flying bird piece is positioned at the bottom of column; little flying bird piece is positioned at the top of column, greatly, the both sides of little flying bird piece respectively by be circular-arc calibrated bolck successively assembly unit connect into closed circular, fixedly connected between piece and the piece.Its advantage is, can save the underground space, reduces construction investment, speed up the work, improves construction quality, can improve the economic benefit of city underground, roads and tunnels investment greatly ..." middle standing pillar of this patent is monolithic, exists big not enoughly aspect anti-seismic performance, and anti-seismic performance is to estimate the important indicator of underground structure.
The utility model content
The purpose of this utility model is the weak point at existing liner structure, and the upright post lining structure of double in a kind of double-O-tube shield method tunnel is provided, about two ring intersections support with two column pieces, improve its anti-seismic performance.
The utility model purpose is realized by following technical scheme:
The upright post lining structure of double in a kind of double-O-tube shield method tunnel is characterized in that the two circular liner structure in tunnel is made of two column pieces, four identical single wing piece and calibrated bolcks more than two of specification.Wherein, erect described two columns between two annulus, two described single wing piece combinations are placed on the top of described two columns, and two single wing pieces make up the bottom that is placed on described two columns in addition.Described single wing piece and described calibrated bolck assembly unit successively form the two annulus of sealing.Be that pre-buried ductile iron hand hole machine nut is connected with the short straight bolt of single head between adjacent two calibrated bolcks and between calibrated bolck and the single wing piece; Between adjacent two single wing pieces straight bolt is fixedlyed connected with nut with straight bolt hole by the trapezoidal hand hole that two pieces are reserved respectively.All seam waterproofs adopt water-swelling rubber water bar.
Two circular pipelines in the utility model intersect the location and depend on its diameter, and common two circle ring center are apart from being R～2R, and R is the annulus outer radius in two annulus tunnels.
Two column spacings in the utility model are R/5～R/6, and R is the annulus outer radius in two annulus tunnels.
The utility model has the advantages that the anti-seismic performance of upright post lining structure of double integral body is better than single upright post type liner structure.Form effective passage in the middle of two columns, personnel can be evacuated after security incident takes place smoothly.Two column center-aisles can be deposited regular maintenance equipment, are convenient to tunnel maintenance.
